Surgical repair of inguinal hernia: tension free technique with prosthetic materials (Gore-Tex Mycro Mesh expanded polytetrafluoroethylene)

The purpose of this study is to report the results of a tension-free repair technique using expanded polytetrafluoroethylene Gore-Tex Mycro Mesh in patients with inguinal hernias. Over 3 years, 104 patients have undergone the aforementioned procedure for 118 hernias (85 indirect and 33 direct) in our clinic. Ninety-three of the patients were operated for the first time, whereas the remainder of them were operated for hernia recurrence. Fourteen patients had bilateral hernias, and six had incarcerated ones. The median patient's age was 53 years. Eighty-three patients were operated under general and 21 under local or epidural anesthesia. One hundred and two patients were offered a one-day surgery procedure, but three were readmitted with wound infection. Two of these patients were conservatively cured, and the third was submitted to mesh removal. Two patients developed hematoma in the scrotum and were discharged a week later after the absorption of the hematoma. All of the patients except the one who was submitted to mesh removal returned to normal life within a week after the operation. During the follow-up period, none of our patients experienced hernia recurrence. Our results are in accordance with those of the world literature. We perform the tension-free hernia repair by using the expanded polytetrafluoroethylene mesh in our patients because we believe it is a safe procedure without significant postoperative morbidity and with no hernia recurrences.     

Incisional hernioplasty with extraperitoneal onlay polyester mesh

Recurrent incisional hernia remains a major problem for the general surgeon. The high recurrence rate of incisional hernias after primary closure by tissue approximation led to the development of tension-free procedures using prosthetic materials. The goal of this study is to present the results of an extraperitoneal tension-free technique using a polyester mesh (Mersilene). A total of 43 patients with incisional hernias were surgically treated during a 9-year period in our department. Twenty-four patients (56%) had recurrent incisional hernias, 21 had primary repair by tissue approximation, and 3 had prolene mesh tension-free repair with wound infection. Patients' mean age was 68.2 years, and the mean postoperative follow-up was 54.4 months. Immediate postoperative complications were noticed in 9 patients (21%) subcutaneous seroma in 6 (14%) and wound infection in 3 (7%). Recurrence was noticed in 4 patients (9%) during the first 9 postoperative months. Late minor complications such as restriction of abdominal wall motility and chronic pain was noticed in 3 (7%) patients. In conclusion, the extraperitoneal onlay tension-free incisional hernia repair using polyester mesh is an easy and safe procedure with no major morbidity or recurrence rate.     

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 Incisional Hernia Repair in Liver Transplant and Other Immunosuppressed Patients

We report the early results of laparoscopic incisional hernia repair in a small group of immunosuppressed patients and compare these results with a cohort of patients with open repair. We describe a modification used to secure the cephalad portion of the Gore-Tex mesh in high epigastric incisional hernias often encountered after liver transplantation. Data were gathered retrospectively for all incisional hernia repairs by our group from March 1996 to January 2001. Twelve of 13 attempted patients had successful completion of their laparoscopic hernia repairs with no reported recurrences to date. Two of these procedures were performed for recurrent hernias. We completed nine of nine attempted laparoscopic hernia repairs in liver transplant patients with epigastric incisional hernias. We repaired two of three attempted lower midline incisional hernias in renal disease patients. One of these patients was soon able to reuse his peritoneal dialysis catheter. A total of 15 patients, 12 with liver transplants, underwent open repair of their incisional hernias. These patients had seven recurrences and/or serious mesh infections with five patients electing repeated operations. In our initial series, laparoscopic mesh repair of incisional hernias is practical and safe in the abdominal organ transplant population with a low incidence of early recurrence and serious infections.     

Laparoscopic ventral hernia repair: an initial institutional experience

BACKGROUND: Ventral and incisional hernias remain a problem for surgeons with reported recurrence rates of 25-50% for open repairs. Laparoscopic approaches offer several theoretical advantages over open repairs. MATERIALS AND METHODS: All patients undergoing a laparoscopic ventral hernia repair from April to December 2000 were prospectively entered in a database. Patients underwent repair with expanded polytetrafluoroethylene dual mesh. Full-thickness abdominal wall nonabsorbable sutures and 5-mm tacks were placed circumferentially. RESULTS: Of 32 patients, 15 underwent incisional repair, 13 had repair of a recurrent incisional hernia, and 4 had repair of a primary abdominal wall defect. Two procedures [2/32; 6.3%] were converted to open, one for loss of abdominal domain and one for neovascularization due to cirrhosis. There were two early recurrences [2/30; 6.7%]. Both of these failures occurred in patients with hernia defects extending to the inguinal ligament, preventing placement of full-thickness abdominal wall sutures inferiorly. Average operating time was 128 +/- 42 min (range 37-225 min). Average length of stay was 1.8 days [range 0-7 days]. There were no transfusion requirements or wound infections. One patient underwent a small bowel resection after completion of repair. One patient required drainage of a seroma 4 weeks after the procedure. CONCLUSIONS: Laparoscopic ventral hernia repair can be safely performed with an acceptable early recurrence rate, operative time, length of stay, and morbidity. Securing the mesh with full-thickness abdominal wall sutures in at least four quadrants remains a key factor in preventing early recurrence.     

Laparoscopic approach to recurrent incisional hernia repair: a 3-year experience

BACKGROUND: Incisional hernias are one of the most frequent complications of open abdominal surgery. The incidence of relapses after a conventional repair procedure is higher in recurrent than in primary cases (30%-50% vs. 11%-20%). The laparoscopic approach can prevent the complications associated with the conventional approach when dealing with recurrent incisional hernias. The aim of this study was to evaluate the efficacy of laparoscopic treatment in such cases. MATERIALS AND METHODS: We prospectively analyzed data from 41 consecutive patients with recurrent incisional hernias, who submitted to a laparoscopic repair procedure with an expanded polytetrafluoroethylene Dual Mesh (Gore-Tex Dual Mesh Plus Biomaterial; W.L. Gore 8 Associates) from December 2001 to December 2004. All of the patients underwent clinical follow-up at 1, 6, and 12 months and then yearly. An ultrasound scan of the abdominal wall was performed at 6 and 12 months after the procedure. The parameters considered for the analysis were: mesh size, operating time, hospital stay, postoperative complications, and recurrences. RESULTS: The defects were usually localized along midline laparotomies. The mean mesh size was 400 cm2, the mean operating time was 68 minutes, and the mean length of hospital stay was 2.7 days. Complications were encountered in 17% of patients. The mean follow-up was 38 months (range, 18-54). Recurrence was reported in 1 case only (2.4%), which occurred within the first 6 months after the operation. CONCLUSIONS: The laparoscopic repair of recurrent incisional hernia seems to be an effective alternative to the conventional approach, as it can give lower recurrence and complication rates.     

Five-year experience with the "four-before" laparoscopic ventral hernia repair

Between 1993 and 1998, we performed a linear study of laparoscopic ventral hernia repair performed in a standard fashion using expanded polytetrafluoroethylene on 49 patients. Eighteen patients had recurrent hernias and 30 patients were morbidly obese with a body mass index >30. Conversion to open procedure was required in two patients. Patients were observed a mean of 27 months. Three patients died of unrelated causes during the observation period. Three patients developed recurrent hernias. By a follow-up survey, we found that 90 per cent of patients were "satisfied" with their operation and results. Because of decreased complications, postoperative pain, hospital stay, and hernia recurrence, the "four-before" laparoscopic repair is our preference for ventral hernias. It has been particularly useful for obese patients and patients with recurrent ventral hernias.

Laparoscopic ventral hernia repair using a two (5-mm) port technique.

OBJECTIVE: High recurrence rates have been documented after primary repair of incisional hernias. Laparoscopic ventral and incisional hernia repairs have been performed with very low rates of recurrence. We have modified the standard technique of laparoscopic repair in patients with small incisional and ventral hernias. The purpose of this study was to document the technique utilizing only two 5-mm ports and demonstrate that it is safe, effective, and feasible. METHODS: Three patients with small incisional or ventral hernias were examined. The standard laparoscopic ventral hernia repair technique was modified as follows: two 5-mm ports were inserted on opposite sides of the defect. The defects ranged from 2.5 cm to 4 cm in size. Expanded polytetrafluoroethylene mesh (DualMesh, WL Gore, Flagstaff, AZ) was used to cover the hernia defect, overlapping the defect margins circumferentially by 3 cm. The mesh diameter ranged from 8.5 cm to 10 cm. The mesh was inserted through a 5-mm skin incision site and affixed into position with transfascial sutures and spiral tacks. RESULTS: The operative time ranged from 53 minutes to 57 minutes. All patients were discharged home the day of surgery and reported minimal postoperative pain. Follow-up ranged from 6 months to 1 year; all patients were doing well without recurrence. CONCLUSION: Laparoscopic repair of ventral or incisional hernias can be performed using only two 5-mm ports. This technique can be done on an outpatient basis in a safe, timely fashion.     

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.     

Medium-term follow-up confirms the safety and durability of laparoscopic ventral hernia repair with PTFE

BACKGROUND: Ventral abdominal wall hernias are common lesions and may be associated with life-threatening complications. The application of laparoscopic principles to the treatment of ventral hernias has reduced recurrence rates from a range of 25% to 52% to a range of 3.4% to 9%. In this study, we review our experience and assess the clinical outcome of patients who have undergone laparoscopic repair of ventral hernias. METHODS: We reviewed the outcome of 79 patients with more than 1 year of follow-up who underwent laparoscopic ventral hernia repair between March 1996 and December 2001. Patient demographics, hernia characteristics, operative parameters, and clinical outcomes were evaluated. RESULTS: Of the 79 patients, 37 were males. Mean age was 55.8 years (range 28-81). Sixty-eight patients had incisional hernias, including 17 with recurrent hernias. Eleven patients had primary ventral hernias. The mean defect size was 103 cm(2) (range 4-510); incarceration was present in 22 patients (27.8%), and multiple (Swiss-cheese) defects in 20 (25.3%). Laparoscopic expanded polytetrafluoroethylene mesh repair by the modified Rives-Stoppa technique was completed in 78 (98.7%). One conversion occurred because of bowel injury. The mean operating time was 110 minutes (range 45-210) and mean hospital stay was 1.7 days (range 0-20), with 46 patients (58.2%) being discharged within 24 hours of surgery. Complications included seroma formation (3), chronic pain (3), prolonged ileus (1), hematoma formation (1), and missed bowel injury (1) for a complication rate of (11.4%). There were no deaths. After a follow-up of up to 6 years (a mean of 34 months), there were 4 recurrences (5%). CONCLUSION: The laparoscopic repair of ventral hernias is safe, effective, and durable with minimal morbidity. It is particularly successful in patients with recurrent lesions. The laparoscopic approach to ventral hernia repair should be considered the standard of care.     

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.

Modified Rives-Stoppa technique for repair of complex incisional hernias in 59 patients

Incisional hernias develop in 2% to 11% of patients who undergo laparotomy. Prosthetic mesh repair provides more strength, tension-free closure, and decreased recurrence rates as compared to primary tissue repairs. Complications-fistula formation, adhesions, skin erosion, and seroma/abscess formation-however, include increased rates of infection, sometimes requiring complete mesh removal. The Rives-Stoppa repair for complex incisional hernias confers the benefits of prosthetic repair and lower recurrence rates, but decreases certain complications by preventing direct mesh contact with the bowel. A total of 89 consecutive patients (mean age, 58.1) underwent a modified Rives-Stoppa repair for purposes of this review, all the patients who lost to follow-up before 6 months postoperatively were excluded from the study. Of the remaining 59 patients, 32.2% (n = 19) had expanded polytetrafluoroethylene mesh, and 67.8% (n = 40) had polypropylene mesh. Average range of follow-up was 40.0 months. Hernia recurred in 1 patient (1.7%). Infection requiring explantation of the prosthesis occurred in 3 patients (5.1%). The Rives-Stoppa repair is reportedly the best open technique for complex incisional hernias with comparatively lower recurrence rates. Additionally, patients with inflammatory bowel disease (64.4% of our series), who often require later reoperation for their primary disease, may benefit from this technique of herniorrhaphy where no interface exists between intrabdominal contents and the prosthesis. This lack of interface decreases intrabdominal adhesions and facilitates re-entry if future surgery is needed for inflammatory bowel disease.     

Incisional hernia—comparison of mesh repair with Cardiff repair: an university hospital experience

Background: Incisional hernia is a frequent complication of abdominal surgery. Various types of repair are recommended for incisional hernia. Suture and mesh repair are compared in the present study. Method: One hundred seventy one patients with incisional hernia underwent Cardiff repair (far and near sutures with reinforcement sutures) which was used as an open suture repair while onlay polypropylene mesh was used in the mesh repair technique. Result: Cardiff repair was performed in 116 patients with no mortality with recurrence in two patients with mean follow up of 7.1 years. Both these patients with recurrence had a defect measuring more than 10 cm in width. Mesh repair was carried out in 55 patients with no recurrence in mean follow up of 37 months. Seroma formation was noted in 7 (12.72%) with mesh repair as compared to 4 (3.44%) patients with Cardiff repair. Conclusion: We recommend Cardiff repair for primary and small to medium size incisional hernias. Onlay polypropylene mesh is ideal for tension-free hernia repair, recurrent incisional hernia and hernia defects wider than 10 cm.     

Use of a new type of PTFE mesh in laparoscopic incisional hernia repair: the continuing evolution of technique and surgical expertise

We present the results of our first 44 laparoscopic incisional hernia repairs. This study examines the effectiveness of this technique in patients presenting with a first-time or recurrent incisional hernia. From October 2001 to November 2002, a total of 45 consecutive patients underwent laparoscopic incisional hernia repair with a new form of expanded polytetrafluoroethylene (ePTFE) mesh. Patient data, preoperative, intraoperative, and postoperative records, were recorded and analyzed. Mean defect size was 84 cm2, mean mesh size was 311 cm2, mean surgical time was 65 minutes, and mean hospital stay was 2.25 days. Postoperative complications occurred in four patients (9.1%). The laparoscopic approach is a safe, effective, and relatively complication-free option in the management of first-time and recurrent incisional hernias. The use of modified ePTFE mesh with a dual surface in incisional hernia repair enables early tissue attachment, reduces adhesions, and could reduce the incidence of recurrences.     

Incisional hernia treatment with progressive pneumoperitoneum and retromuscular prosthetic hernioplasty

BACKGROUND AND AIM: Major incisional hernias of the abdominal wall often pose a serious surgical problem. The choice between simple suture repair and mesh repair remains uncertain. METHODS: Seventy-seven patients underwent surgery to repair large abdominal incisional hernias, i.e., with parietal defects of 10 cm or more, by retromuscular prosthetic hernioplasty between 1996 and 1999. All patients were treated preoperatively by progressive pneumoperitoneum and were followed up for 2-5 years (mean 38.3 months). RESULTS: Almost all patients tolerated the pneumoperitoneum; no postoperative death occurred. Six patients developed a subcutaneous infection but none of them required removal of the mesh. Two patients (2.6%) had recurrent incisional hernia. CONCLUSIONS: This study shows that pneumoperitoneum is useful in preparing patients for incisional hernioplasty. Retromuscular mesh repair represents an appropriate surgical procedure, particularly in view of its low rate of recurrence.     

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.     

“Suture hernia”: identification of a new type of hernia presenting as a recurrence after laparoscopic ventral hernia repair

After laparoscopic repair of ventral or incisional hernias, the recurrence rates reported are around 4%. Different mechanisms for the recurrences have been identified. We report two cases in which the patients were operated on laparoscopically for recurrence after laparoscopic ventral hernia repair. In both cases, the site of the recurrent hernia was situated at the transfascial fixation sutures. Patients were treated by laparoscopy with a larger intraperitoneal mesh covering the new hernia and the old mesh.
