Laparoscopic tension-free repair of anterior abdominal wall incisional and ventral hernias with an intraperitoneal Gore-Tex mesh: prospective study and review of the literature

BACKGROUND: Recurrence rates after repair of incisional and ventral hernias range from 18% to 52%. Prosthetic open repair has decreased this rate, but the wide fascial dissection it requires increases the complication rate. Laparoscopic repair is a safe and effective alternative. PATIENTS AND METHODS: A prospective study was performed including 86 patients (63 women and 23 men) with a mean age of 54 years (range 29-79 years) having incisional or ventral hernias who underwent laparoscopic repair in our institution between July 1994 and October 2001. The majority of the patients were obese with a mean body mass index of 31.7 kg/m2. The abdominal wall defect size ranged from 2 X 1 cm to 20 X 13 cm. In all cases, a Gore-Tex mesh (Dual Mesh, W.L. Gore & Associates, Flagstaff, AZ, USA) was used in sizes ranging from 10 X 15 cm to 20 X 30 cm. RESULTS: Nineteen repairs were performed for recurrent hernias (12 incisional and 7 ventral). The mean operative time was 110.3 minutes (range 50-240 minutes). There was one open conversion (1.2%), one intraoperative complication (1.2%), and no deaths. There were no wound or mesh infections. Immediate postoperative complications occurred in 9 patients (10.6%) and late complications occurred in 16 patients (18.8%). The average hospital stay was 4.8 days (range 2-19 days). During a mean follow-up of 37 months (range 6-73 months), there were 6 hernia recurrences (7%). CONCLUSION: Laparoscopic repair of incisional hernia and ventral hernia appears to be safe, especially with the use of Gore-Tex mesh, and is proving to be effective as it decreases pain, complications, hospital stay, and recurrences.     

Laparoscopic sutured closure with mesh reinforcement of incisional hernias

Background This study reports medium-term outcomes of laparoscopic incisional hernia repair. Study Design Laparoscopic repair was performed on 721 patients with ventral hernia. After adhesiolysis the defect was closed with no. 1 polyamide suture or loop. This was followed by reinforcement with intraperitoneal onlay repair with a bilayered mesh. Results Laproscopic repair of ventral hernia was performed on 613 females and 108 males. Of these, 185 (25.7%) were recurrent incisional hernias of which 93 had undergone previous open hernioplasty. The remaining 92 patients had previously undergone sutured repair. The average operating time was 95 min (range 60–115 min). Conversion rate was 1%. The average hospital stay was 2 days (range 1–6 days). The commonest complication was seroma formation at the incisional hernia site. Full-thickness bowel injury occurred in two patients. The mean follow-up period was 4.2 years (range 3 months to 10 years). Recurrence was noted in four (0.55%) patients. Conclusion Laparoscopic repair is well-tolerated and can be accomplished with minimum morbidity in ventral hernias.     

Laparoscopic ventral hernia repair

Introduction: Effective surgical therapy for ventral and incisional hernias is problematic. Recurrence rates following primary repair range as high as 25–49%, and breakdown following conventional treatment of recurrent hernias can exceed 50%. As an alternative, laparoscopic techniques offer the potential benefits of decreased pain and a shorter hospital stay. This study evaluates the efficacy of the laparoscopic approach for ventral herniorrhaphy. Methods: A retrospective review was performed for 100 consecutive patients with ventral hernias who underwent laparoscopic repair at our institutions between November 1995 and May 1998. All patients who presented during this period and were candidates for a mesh hernia repair were treated via an endoscopic approach. Results: One hundred patients underwent a laparoscopic ventral hernia repair. There were 48 men and 52 women. The patients were typically obese, with a mean body mass index (BMI) of 31 kg/m². Each had undergone an average of 2.5 (range; 0–8) previous laparotomies. Forty-nine repairs were performed for recurrent hernias. An average of two patients (range; 1–7) had previously failed open herniorhaphies; in 20 cases, intraabdominal polypropylene mesh was present. There were no conversions to open operation. The mean size of the defects was large at 87 cm² (range; 1–480). In all cases, the mesh (average, 287 cm²) was secured with transabdominal sutures and metal tacks or staples. Operative time and estimated blood loss averaged 88 min (range; 18–270) and 30 cc (range; 10–150). Length of stay averaged 1.6 days (range; 0–4). There were 12 minor and (two) major complications: cellulitis of the trocar site (two), seroma lasting >4 weeks (three), postoperative ileus (two), suture site pain > 2 weeks (two), urinary retention (one), respiratory distress (one), serosal bowel injury (one), and skin breakdown (one) and bowel injury (one). Both of the latter complications required mesh removal. With an average follow-up of 22.5 months (range; 7–37), there have been (three) recurrences. Conclusion: The laparoscopic approach to the repair of both primary and recurrent ventral henias offers a low conversion rate, a short hospital stay, and few complications. At 23 months of follow-up, the recurrence rate has been 3%. Laparoscopic repair should be considered a viable option for any ventral hernia.

Laparoscopic repair of large incisional hernias

Incisional hernias after abdominal operations are a significant cause of long-term morbidity and have been reported to occur in 3 to 20 per cent of laparotomy incisions. Traditional primary suture closure repair is plagued with up to a 50 per cent recurrence rate. With the introduction of prosthetic mesh repair recurrence decreased, but complications with mesh placement emerged ushering in the development of laparoscopic incisional herniorrhaphy. The records of patients who underwent laparoscopic incisional hernia repair between June 1, 1995 and September 1, 2001 were reviewed. Patient demographics, hernia defect size, recurrence, operative time, and procedure-related complications were evaluated. Fifty patients (22 male and 28 female, mean age 57 years with range of 24-83) were scheduled for laparoscopic incisional hernia repair between June 1, 1995 and September 1, 2001. The average patient was obese with a mean body mass index of 35.8 kg/m2 (range 16-57 kg/m2). Two patients (4%) had primary ventral hernias. Forty-eight patients (96%) had incisional hernias with 22 (46%) of these previously repaired with prosthetic mesh. Mean defect size was 206.1 cm2 (range 48-594 cm2). The average mesh size was 510.2 cm2 (range 224-1050 cm2). Gore-Tex DualMesh and Bard Composite Mesh were used in 84 and 16 per cent of the repairs, respectively. Mean operating time was 97 minutes. There were no deaths. Complications were seen in 12 per cent patients (six occurrences) and included two small bowel enterotomies, a symptomatic seroma requiring aspirate, a mesh reaction requiring a short course of intravenous antibiotics, and trocar site pain (two patients). There were no recurrences during a mean follow-up of 41 months (range 3-74 months). We conclude that laparoscopic incisional herniorrhaphy offers a safe and effective repair for large primary and recurrent ventral hernia with low morbidity.     

Laparoscopic repair of ventral hernias: nine years' experience with 850 consecutive hernias

OBJECTIVE: To evaluate the efficacy and safety of laparoscopic repair of ventral hernias. SUMMARY BACKGROUND DATA: The recurrence rate after standard repair of ventral hernias may be as high as 12-52%, and the wide surgical dissection required often results in wound complications. Use of a laparoscopic approach may decrease rates of complications and recurrence after ventral hernia repair. METHODS: Data on all patients who underwent laparoscopic ventral hernia repair (LVHR) performed by 4 surgeons using a standardized procedure between November 1993 and October 2002 were collected prospectively (85% of patients) or retrospectively. RESULTS: LVHR was completed in 819 of the 850 patients (422 men; 428 women) in whom it was attempted. Thirty-four percent of completed LVHRs were for recurrent hernias. The patient mean body mass index was 32; the mean defect size was 118 cm2. Mesh, averaging 344 cm2, was used in all cases. Mean operating time was 120 min, mean estimated blood loss was 49 mL, and hospital stay averaged 2.3 days. There were 128 complications in 112 patients (13.2%). One patient died of a myocardial infarction. The most common complications were ileus (3%) and prolonged seroma (2.6%). During a mean follow-up time of 20.2 months (range, 1-94 months), the hernia recurrence rate was 4.7%. Recurrence was associated with large defects, obesity, previous open repairs, and perioperative complications. CONCLUSION: In this large series, LVHR had a low rate of conversion to open surgery, a short hospital stay, a moderate complication rate, and a low risk of recurrence.     

Ventral Hernia Repair in Bariatric Surgery

Background: Obesity is an important risk factor for perioperative complications including the development of ventral hernias. Methods: This retrospective study comprises patients who underwent abdominal hernia repair simultaneously with or following implantation of a Swedish Adjustable Gastric Band? (SAGB). Results: 9 out of 415 patients (2.2%) who received a SAGB between January 1996 and June 2001 underwent ventral hernia repair. In 6 patients, hernias preexisted from previous abdominal surgery at the time of the bariatric procedure, and another 3 hernias occurred at the median and left upper abdominal trocar position following SAGB placement. Median BMI at time of SAGB implantation was 44 (range 35-52), and at time of hernia repair was 36 (range 25-46). 2 hernias were repaired during SAGB placement, 3 during redo surgery, and 2 during abdominoplasty. In 2 patients, significant weight loss with loss of soft tissue support of the hernia sac led to recurrent episodes of small bowel obstruction necessitating emergency repair. Repair included direct defect closure in 7 patients and sublay polypropylene net implantation in 2 patients. Recoveries have been uneventful without wound infections or recurrence in all patients after a median follow-up of 34 months (range 13-69). Conclusion: In morbidly obese patients, the optimal management and timing of incisional hernia repair should weigh the risk of recurrence and perioperative complications against the risk of hernia-associated complications.     

Laparoscopic ventral and incisional hernia repair: An 11-year experience

Incisional hernias develop in 2%–20% of laparotomy incisions, necessitating approximately 90,000 ventral hernia repairs per year. Although a common general surgical problem, a "best" method for repair has yet to be identified, as evidenced by documented recurrence rates of 25%–52% with primary open repair. The aim of this study was to evaluate the efficacy and safety of laparoscopic ventral and incisional herniorrhaphy. From February 1991 through November 2002, a total of 384 patients were treated by laparoscopic technique for primary and recurrent umbilical hernias, ventral incisional hernias, and spigelian hernias. The technique was essentially the same for each procedure and involved lysis of adhesions, reduction of hernia contents, closure of the defect, and 3–5 cm circumferential mesh coverage of all hernias. Of the 384 patients in our study group, there were 212 females and 172 males with a mean age of 58.3 years (range 27–100 years). Ninety-six percent of the hernia repairs were completed laparoscopically. Mean operating time was 68 min (range 14–405 min), and estimated average blood loss was 25 mL (range 10–200 mL). The mean postoperative hospital stay was 2.9 days and ranged from same-day discharge to 36 days. The overall postoperative complication rate was 10.1%. There have been 11 recurrences (2.9%) during a mean follow-up time of 47.1 months (range 1–141 months). Laparoscopic ventral and incisional hernia repair, based on the Rives-Stoppa technique, is a safe, feasible, and effective alternative to open techniques. More long-term follow-up is still required to further evaluate the true effectiveness of this operation.     

Laparoscopic repair of incisional and ventral hernia

The application of laparoscopic principles to ventral or incisional hernia repair has recently been shown to be a safe and effective alternative to open procedures. In this study we analyzed our recent experience with laparoscopic incisional-ventral hernia repair. The outcomes of 75 consecutive patients (January 2002 to July 2006) who underwent laparoscopic repair for incisional-ventral hernia were reviewed. Patient's demographics, hernia parameters, and intraoperative and postoperative data were collected. Of the 75 patients, 44 were females and 31 males. Mean age was 59.1 yrs (range 29-80 yrs). Mean BMI was 25.9 (range 19.4-36.7). Twenty-one patients had primary ventral hernias while 54 patients had an incisional hernia. Fifty-three patients had a single defect and 22 patients multiple defects. In 45 cases the incisional hernia was a primary hernia; in 4 cases it was a first recurrence; in 2 cases a 2nd recurrence; and in 3 cases a 3rd recurrence. The mean defect size was 52,7 cm2 (range 4-432). Laparoscopic hernia repair was successfully performed in 71 cases (94.7%). The mean mesh size was 211 cm2 (range 63-694). Mean operating time was 101 min (range 50-220 min). The mean hospital stay was 4.7 days. The postoperative morbidity rate was 14%. After a mean follow-up of 24.6 months (range 7-56) the recurrence rate was 7% (5/71). Laparoscopic repair of incisional-ventral hernias seems to be safe and effective. Medium-term outcomes were promising with a relatively low rate of conversion to open surgery, a low complication rate and a low risk of recurrence.     

Laparoscopic repair of recurrent inguinal hernia

Background: Laparoscopic repair is becoming a popular treatment for recurrent inguinal hernia. The true long-term recurrence of this method is unknown. Methods: Patients who underwent laparoscopic recurrent inguinal hernia repair at our institution were followed up. Patients were interviewed by phone at least 6 months following surgery and examined by the same surgeon. Results: Between April 1995 and November 2000, 150 laparoscopic repairs of recurrent inguinal hernia were performed in 130 patients. The average operative times were 56 and 68 min for unilateral and bilateral repairs, respectively. There was one conversion to an open procedure. Three patients had intraoperative complications, all identified and repaired laparoscopically. Minor postoperative complications occurred in 24 patients (18.5%), seroma being the most common. There were no injuries to the bowel or major vessels. The average postoperative stay was 1.3 days (range, 0.5–13). Average follow-up was 37 months (range, 7–75). In all, 123 patients (94.6%) were available for interview. Regular activity was resumed by 10.7 days (range, 1–90) and strenuous activity at 24.5 days (range, 1–90). A total of 106 patients with 122 hernias (81.3%) were examined. There were seven recurrent hernias (5.7%). Conclusions: Laparoscopic repair of recurrent inguinal hernia is effective and has superior long-term results as compared to historical series. If the cost could be reduced, it should probably become the method of choice for the repair of recurrent inguinal hernia.     

Laparoscopic repair of recurrent hernias

BACKGROUND: Recurrence after primary conventional inguinal herniorrhaphy occurs in approximately 10% of patients depending on the type of repair and expertise of the surgeon. The repair of the resulting recurrent hernia is a daunting task because of already weakened tissues and obscured and distorted anatomy. The failure rate of these repairs using an open anterior approach may reach as high as 36%. Because of such a high failure rate, a number of investigators have focused on repairing these difficult recurrent hernias laparoscopically using a tension-free approach. Some of the earlier reports suggested a low recurrence rate of 0.5% to 5% when a laparoscopic approach was used to repair these hernias. The purpose of this study was to evaluate the efficacy of laparoscopic treatment for recurrent hernias in our institutions. METHODS: Between February 1991 and February 1995, 96 recurrent hernias were repaired in 85 patients (78 men and 7 women). There were 48 right, 26 left, and 11 bilateral hernias. The mean age of the patients was 59 years (range, 18-86 years); the mean height was 69 in. (range, 54-77 in.); and the mean weight was 176 pounds (range, 109-280 pounds). A total of 68 herniorrhaphies were performed using the transabdominal preperitoneal (TAPP) method: 19 using intraperitoneal on-lay mesh (IPOM) repair and 8 using the total extraperitoneal (TEP) method. The method of repair in one patient was not recorded. The mean operating time was 76 min (range, 47-172 min). Thirteen patients underwent additional procedures. RESULTS: Long-term follow-up was performed by questionnaire, examination, or both in 76 patients (85 hernias). Median follow-up time was 27 months (range, 2-56 months). There were four recurrences (2 in IPOM and 2 in TAPP). Three of these were repaired laparoscopically and one conventionally. There were 20 minor and 14 major complications and no mortality. One conversion occurred in the TAPP group. Mean postoperative stay was 1.4 days (range, 0-4 days). It was felt by 92% of the patients that their symptoms were completely relieved, whereas 4% of the patients continued to exhibit symptoms for which their hernia was repaired, and 3.6% failed to answer. As reported, 86% of the patients preferred their laparoscopic repair; 1% preferred the conventional repair; and 13% failed to reply. Afterward, 77% of the patients returned to normal activity, and 35% returned to vigorous activity within 4 weeks of surgery. Satisfaction with laparoscopic repair was expressed by 92% of the patients, whereas 8% either were dissatisfied or did not answer. In the end, 95% of the patients stated that they would recommend laparoscopic hernia surgery to their family and friends. CONCLUSIONS: These preliminary data show that laparoscopic repair of recurrent inguinal hernia is a safe alternative procedure with acceptable rates of recurrence and complications.     

Laparoscopic repair of ventral incisional hernia

Background : Laparoscopic repair of ventral incisional hernias was first reported in 1993. Since then, there have been sporadic case reports and small series published about this procedure, but it has not been widely adopted. Newer types of composite prosthetic mesh may reduce the potential problem of bowel adhesion. Methods : Thirty cases of laparoscopic ventral incisional hernia repairs (carried out by two surgeons or their senior registrars) have been retrospectively reviewed and reported in this article. The data were obtained from patient records and subsequent phone surveys. Results : Thirty patients between 29 and 82 years (mean: 58 years) underwent this procedure. There were 14 men and 16 women. The average weight of the patients was 81 kg. The hernias were up to 6 or 7 cm in diameter. Mesh was used in 28 cases (polypropylene in 25 cases, expanded polytetrafluoroethylene in two cases and composite mesh in one case). Most meshes were laid intraperitoneally and fixed into position with laparoscopic spiral tacks. Twenty‐nine cases were completed laparoscopically. One operation (3.3%) was converted to an open procedure because of severe bowel adherence to the hernia sac. The mean operating time was 52 min for laparoscopic ventral incisional hernia repairs only. All but two patients tolerated an oral diet within 24 h. The postoperative hospital stay ranged from 0 to 11 days, with 17 patients (57%) staying overnight and eight patients (27%) staying another day. Over 80% of the patients returned to house duties within a week. There was no mortality, and minor complications occurred in four patients (14%). One patient had a small bowel obstruction treated successfully by repeat laparoscopy with division of fibrinous adhesions to polypropylene mesh on day four. Follow up ranged from 1 to 69 months (mean: 12 months). One patient did not attend follow‐up appointments. There were three cases of hernia recurrence (10%). Conclusion : The results suggest that laparoscopic repair of ventral incisional hernias is a safe, effective and technically feasible operation for small‐ to medium‐sized hernias allowing shorter hospital stay, early recovery and resumption of normal activities. However, recurrence rates are comparable to open mesh hernioplasty especially for larger hernias.     

Laparoscopic inguinal hernia repair on a general surgery ward: 5 years' experience

BACKGROUND: Laparoscopic hernia repair has been gaining acceptance as an alternative to open repair. The aim of this study was to present the experience of a general surgery ward with laparoscopic inguinal hernia repair. MATERIALS AND METHODS: A retrospective search of all laparoscopic inguinal hernia repairs between January 1999 and December 2003 was obtained. Data, including perioperative course, postoperative complication, and long-term follow-up, was documented. RESULTS: A total of 423 hernias were repaired in 220 patients. Long-term follow-up was performed by questionnaire, clinic visit, or both in 182 of the 220 patients (82.7%). Median follow-up time was 27.5 (range, 4-61) months. Two hundred and three (92.3%) hernias were bilateral. Fifty-seven patients (25.9%) had recurrent hernias. There was no conversion to an open hernia repair. There were 10 recurrences (2.3%). Minor complications (e.g., abdominal wall hematoma, epigastric vessels injury, and urinary retention requiring catheterization) occurred in 17 (7.7%) patients. A bladder injury occurred in 1 patient (0.45%). There was no mortality. Mean postoperative stay was 1.1 days (range, 1-10). Satisfaction with the laparoscopic repair was expressed by using a scoring system of 1 to 5, with 85.2% being very satisfied (score of 4-5) and 8.2% being dissatisfied (score of 1-2). CONCLUSIONS: The laparoscopic herniorrhaphy offers a safe and effective repair with acceptable complication and recurrence rates. Good results with the total extraperitoneal technique can be achieved by general laparoscopists and not only in highly specialized hernia centers. It is especially suited for bilateral repair and for recurrent hernias.     

Perioperative outcomes and complications of laparoscopic ventral hernia repair

BACKGROUND: Laparoscopic techniques are being used increasingly in the repair of ventral hernias and offer the potential benefits of a shorter hospital stay, decreased wound complications, and possibly a lower recurrence rate. Despite good results from high-volume centers, significant complications may occur with this approach and the morbidity of incisional hernia repair may be underestimated. The purpose of this study was to review our experience with laparoscopic ventral hernia repair (LVHR) since its inception at our institution. METHODS: Medical records of all patients who underwent LVHR at a single institution from May 2000 through December 2003 were reviewed. Preoperative and postoperative variables including complications were analyzed. Follow-up evaluation was by office visit and phone survey with assessment of patient satisfaction scores. Data are expressed as mean +/- SD. RESULTS: A total of 121 LVHR were performed in 116 patients (52 men, 64 women; mean age, 57 +/- 13 y; mean body mass index, 35 +/- 8). Hernias were recurrent in 35 cases (28.9%), with a mean of 1.4 prior repairs (range, 1-7). The mean defect size was 109 +/- 126 cm2 and the average mesh size used was 256 +/- 192 cm2. Operating time was 147 +/- 45 minutes, and the hospital stay averaged 1.7 +/- 1 days. Twelve cases (9.9%) were converted to open operation, most commonly because of extensive adhesions. Extensive laparoscopic adhesiolysis was necessary in 29 cases (26.6%). Overall, perioperative complications occurred in 33 cases (27.3%), 13 of which (39.3%) were persistent seromas. Major complications were seen in 9 cases (7.4%). There were 4 enterotomies (3.3%): 3 occurred as a result of adhesiolysis and 1 resulted from a trocar injury; 2 were detected intraoperatively and were converted to open operation and 2 presented postoperatively. One of these patients developed sepsis and died. Follow-up evaluation was available for 83.6% of cases at a mean interval of 22 +/- 16 months after repair. The hernia recurrence rate was 9.3% (9 cases) and was detected at a median of 6 months postoperatively. The overall patient satisfaction score was high at 4.3 +/- 1.1 (scale, 1-5). CONCLUSIONS: Laparoscopic repair is effective for the vast majority of patients with primary or recurrent ventral hernias and results in hernia recurrence rates of less than 10%, with high patient satisfaction scores. Although seroma is the most common complication, major morbidity occurred in 7.4% of the patients in our series. Enterotomy is the most common serious complication and may result in sepsis and death.     

Technique and outcomes of abdominal incisional hernia repair using a synthetic composite mesh: a report of 455 cases

BACKGROUND: Abdominal wall hernias are a frequent and formidable challenge for general surgeons. Several different surgical techniques and types of mesh prosthetics are available for repair. We evaluated outcomes of an open ventral hernia repair using a synthetic composite mesh. STUDY DESIGN: We prospectively collected data on consecutive patients undergoing open ventral hernia repair using a synthetic composite mesh from January 1, 2000 to December 31, 2005 at four large medical centers. Four surgeons used a standardized surgical procedure for all patients. RESULTS: The study consisted of 455 patients with an average age of 56 years; 54% were men. Sixty-nine percent of the patients underwent repairs for recurrent hernias. Mean defect size was 44 cm(2), and mean mesh size was 213 cm(2). Average length of hospital stay was 1.1 days. Thirty-one patients had 33 early complications (7%), and 3 patients (0.7%) required reoperation (one each for seroma, bowel injury, and wound breakdown). Early infection occurred in four patients (0.9%), and one patient required reoperation and graft removal. Late complications occurred in nine patients (2%), with two patients requiring reoperation. Late infections occurred in two patients (0.4%); both required antibiotic treatment. Recurrent hernias were observed in 6 patients (1%; 6 of 450 because of 5 patients with unknown recurrence) at a mean followup of 29.3 months. CONCLUSIONS: In this large multicenter series, open ventral hernia repair using a composite mesh resulted in a short hospital stay, moderate complication rate, low infection rate, and low recurrence rate.     

Polyester-based mesh for ventral hernia repair: is it safe?

Introduction

The ideal prosthetic material for ventral hernia repair has yet to be described. Each prosthetic material has unique advantages and disadvantages in terms of tissue ingrowth, adhesion formation, and shrinkage profiles. Polyester-based mesh has shown minimal shrinkage and excellent tissue ingrowth in animal models. However, the macroporous, braided nature of this material has raised several concerns regarding the incidence of infections, fistulas, and bowel obstructions. We have reviewed our experience with polyester-based mesh for the repair of ventral hernias.

Methods

All patients undergoing ventral hernia repair at the Case Comprehensive Hernia Center at University Hospitals of Cleveland from December 2005 to April 2008 were included. Laparoscopic cases underwent intraperitoneal placement of a polyester-based mesh with a collagen hydrogel anti-adhesive barrier. The mesh was sized for at least 4 cm of fascial overlap, and transfascial fixation sutures and titanium spiral tacks were used routinely to secure the mesh to the abdominal wall. Those cases deemed inappropriate for laparoscopic ventral hernia repair underwent open repair. Open ventral hernia repairs were performed using a retrorectus repair, placing the mesh in an extraperitoneal position. Unprotected polyester mesh was used in these cases. Pertinent data included patient demographics, surgical details, postoperative outcomes, and long-term follow-up evaluation.

Results

During the study period 109 patients underwent ventral hernia repair with polyester mesh. Seventy-nine patients had a laparoscopic repair, and 30 patients had an open repair. The mean age was 57 years, with a mean body mass index of 33 kg/m², and American Society of Anesthesia score of 2.6. The patients had undergone 2.1 prior abdominal surgical procedures, and 42 patients had recurrent hernias. Surgical details for the laparoscopic repair and open repair were as follows: mean defect size, 116 versus 403 cm²; mesh size, 367 versus 1,055 cm²; and surgical times, 132 versus 170 minutes, respectively. The average hospital stay was 4.2 days for the laparoscopic repair and 5.8 days for the open repair groups. With a mean follow-up period of 14 months (range, 2-28 mo) in the laparoscopic repair group, 1 patient (1.4%) developed a mesh infection (with a history of a prior methicillin-resistant Staphylococcus aureus mesh infection), 1 patient (1.4%) developed a small-bowel obstruction remote to the mesh on re-exploration, and there were no fistulas. With a mean follow-up period of 11 months (range, 2-21 mo) in the open repair group, 3 wound infections (13%) occurred, 2 involved the mesh, which was salvaged with local wound care in 1, and required partial mesh resection in the other, and there were no bowel obstructions or fistulas during the follow-up evaluation.

Conclusions

This study shows that in this complex group of patients, polyester mesh placed during ventral hernia repair results in acceptable infection rates, and no direct bowel complications or fistulas. Given the macroporous nature of the mesh, each case of infection was treated successfully with local wound measures or partial mesh resection. Polyester-based meshes with an anti-adhesive barrier appear safe for intraperitoneal placement.     

The feasibility of adopting laparoscopic incisional hernia repair in general surgery practice: early outcomes in an unselected series of patients

A laparoscopic approach to incisional hernia repair has been shown to be safe and effective in selected patients. We report our early outcomes following laparoscopic ventral/incisional hernia repair (LVHR) in an unselected series of patients encountered in general surgery practice. All patients referred with incisional hernia were offered a laparoscopic repair using prosthetic mesh. Patients were not excluded from laparoscopic approach on the basis of age, previous surgery, defect size, intraperitoneal mesh, body mass index (BMI), comorbidities, or abdominal wall stomas. We followed 28 consecutive patients who underwent LVHR (17 primary, 11 recurrent hernias). Laparoscopic repair was completed in 27 patients with a mean operative time of 141.6 +/- 11.9 minutes. There were no intraoperative complications. The mean size of the abdominal wall defects was 153.4 +/- 27.5 cm and the mean mesh size was 349.2 +/- 59.1 cm. The mean hospital stay was 3.7 +/- 0.3 days. Nine patients developed large wound seromas; all spontaneously resolved. Our experience suggests that LVHR is feasible as a primary approach to most incisional hernias encountered in general surgery practice.     

Closure versus non-closure of hernia defect during laparoscopic ventral hernia repair with mesh

Purpose

Laparoscopic ventral hernia repair with mesh versus laparoscopic ventral hernia defect closure with mesh reinforcement. The primary end-point was recurrence.

Methods

Retrospective review of patients who underwent laparoscopic ventral hernia repair for small- and medium-sized hernias between July 2000 and September 2011. These patients were divided: (1) repair with mesh alone (non-closure group) and (2) those with hernia defect closure and mesh reinforcement (closure group). The closure group was further divided by technique: percutaneous versus intracorporeal closure of the defect.

Results

128 patients were studied: 93 patients (72.66 %) in the non-closure group and 35 patients (27.34 %) in the closure group. Follow-up was available in 105 patients (82.03 %) at a mean of 797.2 days (range 7–3,286 days). In the non-closure group there were 14 patients (15.05 %) with postoperative complications and 8 patients (22.86 %) in the closure group, four of which were seromas. Fourteen patients (19.18 %) developed recurrent hernias in the non-closure group with an average time to presentation of 23.17 months (range 5.3–75.3). Two patients (6.25 %) developed recurrent hernias in the percutaneous group with an average time to presentation of 12.95 months (range 9.57–16.33). There have been no recurrences in patients whose defect was closed intracorporeally.

Conclusion

Although our study demonstrated a difference in recurrence rates of 19.18 % in the non-closure group versus 6.25 % in the closure group, the difference did not reach statistical significance. A larger series with longer follow-up may demonstrate clinical significance.     

Laparoscopic repair of incarcerated ventral abdominal wall hernias

Background  The role of laparoscopy in the management of incarcerated (irreducible) ventral hernia remains to be elucidated. We present our experience of the laparoscopic repair of incarcerated primary ventral and incisional hernias over an 8-year period. Methods  A retrospective review of the records of 112 patients undergoing laparoscopic repair for incarcerated primary ventral and incisional hernias from January 1998 to February 2006 was performed. The patient demographics, perioperative data, and postoperative complications were assessed. Results  The procedure was completed entirely laparoscopically in 103 patients (91.9%) with the placement of intraperitoneal mesh. A sutured tissue repair (without mesh) was performed in seven patients and hernia repair was abandoned after laparoscopy in two patients. Five patients required limited conversion by a targeted skin incision for the resection of nonviable bowel (three patients) and to complete adhesiolysis within multiloculated hernial sacs (two patients). The contents of the hernial sacs were incarcerated omentum (42 patients), small bowel (28 patients), large bowel (six patients), and omentum and small bowel (34 patients). Of these, seven patients presented with signs of acute small-bowel obstruction. The mean size of the largest defect through which incarceration occurred was 3.5 ± 1.6 cm (range 1.5–7.5 cm) and the mean size of the mesh used was 379 ± 210 cm² (range 225–780 cm²). The mean operative time was 96 ± 40.8 min (range 50–170 min). Inadvertent enterotomy occurred in four patients during bowel reduction and adhesiolysis. In two patients, the enterotomy was repaired by total laparoscopy followed by mesh placement, and two patients required conversion to formal laparotomy due to long-segment tears and peritoneal contamination. The average postoperative hospital stay was 2.8 ± 1.5 days (range 1–6.5 days). Postoperative complications occurred in 20.5% patients. There was no mortality. Hernia recurred in three patients at a mean follow-up of 48 ± 28.3 months (range 1–84 months). Conclusion  Laparoscopic ventral abdominal wall hernia repair can be safely performed with a low complication rate, even in incarcerated hernias. Careful bowel reduction with adhesiolysis and mesh repair in an uncontaminated abdomen with a 5-cm mesh overlap remain key factors for a successful outcome.     

Totally extraperitoneal laparoscopic inguinal hernia repair is a safe option in patients with previous lower abdominal surgery

BACKGROUND: History of inguinal hernia repair changed over the decades from repair by tissue approximation to the insertion of synthetic mesh and the introduction of laparoscopic repair. Despite accounting for 15-20% of hernia operations worldwide, many surgeons considered previous lower abdominal surgery as a contraindication to performing totally extraperitoneal (TEP) repair. AIM: The aim of this study was to assess the feasibility of TEP in primary and recurrent inguinal hernias in patients with previous lower abdominal surgery. PATIENTS AND METHODS: This study was a retrospective review of patients who underwent TEP inguinal hernia repair from January 2001 to July 2005. Variables studied included patient demographics, type of hernia, type of previous surgery, conversion to open repair, postoperative complications, and overnight admission. RESULTS: One hundred eight patients (107 males, 1 female), with a median age of 55 years (range 87-24), underwent TEP repair. Ninety-four patients had primary inguinal hernias, and 13 patients had recurrent inguinal hernias. Seventeen patients had a previous lower abdominal surgery (13 primary and 4 recurrent inguinal hernias). There was 1 conversion to open repair and 1 case of postoperative bleeding that required an exploration-both in the group with no previous surgery. Postoperative complications were minimal. All cases were performed as day cases; however, patients with recurrent hernia stayed longer in the hospital than those with primary hernia (P = 0.006). CONCLUSION: TEP repair is feasible in patients with previous lower abdominal surgery. TEP was planned as a day-case procedure; however, patients with recurrent hernias needed a planned admission, as an overnight stay was required.     

Laparoscopic ePTFE mesh repair of incisional and ventral hernias

Incisional hernia is a relatively frequent complication of abdominal surgery. The use of mesh to repair incisional and ventral hernias results in lower recurrence rates compared with primary suture techniques. The laparoscopic approach may be associated with lower postoperative morbidity compared with open procedures. Long-term recurrence rates after laparoscopic ventral and incisional hernias are not well defined. A prospective study of the initial experience of a standardized technique of laparoscopic incisional and ventral hernia repair carried out in a tertiary referral hospital was undertaken between January 2003 and February 2007. Laparoscopic hernia repair was attempted in 71 patients and was successful in 68 (conversion rate 4%). The mean age of the patients identified was 63.1 years (39 men and 31 women). Multiple hernial defects were identified in 38 patients (56%), and the mean overall size of the fascial defects was 166 cm(2). The mean mesh size used was 403 cm(2). The mean operative time was 121 minutes. There were six (9%) major complications in this series, but there were no deaths. Hernia recurrence was noted in four patients (6%) at a mean follow up of 20 months. Our preliminary experience indicates that laparoscopic incisional and ventral hernia repair is technically feasible and has acceptable postoperative morbidity and low early recurrence rates.
