Laparoscopic versus open ventral hernia mesh repair: a prospective study

Background An incisional hernia develops in 3% to 13% of laparotomy incisions, with primary suture repair of ventral hernias yielding unsatisfactory results. The introduction of a prosthetic mesh to ensure abdominal wall strength without tension has decreased the recurrence rate, but open repair requires significant soft tissue dissection in tissues that are already of poor quality as well as flap creation, increasing complication rates and affecting the recurrence rate. A minimally invasive approach was applied to the repair pf ventral hernias, with the expectation of earlier recovery, fewer postoperative complications, and decreased recurrence rates. This prospective study was performed to objectively analyze and compare the outcomes after open and laparoscopic ventral hernia repair. Methods The outcomes for 50 unselected patients who underwent laparoscopic ventral hernia repair were compared with those for 50 consecutive unselected patients who underwent open repair. The open surgical operations were performed by the Rives and Stoppa technique using prosthetic mesh, whereas the laparoscopic repairs were performed using the intraperitoneal onlay mesh (IPOM) repair technique in all cases. Results The study group consisted of 100 patients (82 women and 18 men) with a mean age of 55.25 years (range, 30–83 years). The patients in the two groups were comparable at baseline in terms of sex, presenting complaints, and comorbid conditions. The patients in laparoscopic group had larger defects (93.96 vs 55.88 cm²; p = 0.0023). The mean follow-up time was 20.8 months (95% confidence interval [CI], 18.5640–23.0227 months). The mean surgery durations were 90.6 min for the laparoscopic repair and 93.3 min for the open repair (p = 0.769, nonsignificant difference). The mean postoperative stay was shorter for the laparoscopic group than for the open hernia group (2.7 vs 4.7 days; p = 0.044). The pain scores were similar in the two groups at 24 and 48 h, but significantly less at 72 h in the laparoscopic group (mean visual analog scale score, 2.9412 vs 4.1702; p = 0.001). There were fewer complications (24%) and recurrences (2%) among the patients who underwent laparoscopic repair than among those who had open repair (30% and 10%, respectively). Conclusions The findings demonstrate that laparoscopic ventral hernia repair in our experience was safe and resulted in shorter operative time, fewer complications, shorter hospital stays, and less recurrence. Hence, it should be considered as the procedure of choice for ventral hernia repair.     

Comparison between modern mesh and conventional non-mesh methods of inguinal hernia repair

BACKGROUND: The objectives of the study were to compare the tension-free mesh repair with non-meash conventional repair of groin hernia. METHODS: In the past two years in 299 consecutive unselected patients 339 inguinal hernia repairs were carried out. They randomly allocated to undergo either a non-meash modified Bassini's repair (n=164) or a tension-free mesh repair (n=175). The latter group consisted of laparoscopic TAPP repair (n=46) and open onlay patch repair (n=64) or plug and patch repair (n=65). Operation time, postoperative pain and complications, hospital stay, return to work and recurrence were assessed. Statistical analysis was made using the "t"-Student test. RESULTS: The characteristics of the patients in each group and the operation time did not differ significantly. The planned procedure was completed in all and no death occurred. The analgesic requirements (none 2.5 vs 56.4%, opiods 77 vs 23.6%), complication rate (9.4 vs 4.3%), hospital stay (4.2 vs 1.8 days), return to work (17.2 vs 7.3 days) and recurrence rate (5.5 vs 1.2%) in non-mesh group were more than in the mesh group. All differences were statistically significant (p<0.05). Among the three subgroups of mesh group no statistically significant differences (p>0.05) were found. CONCLUSIONS: The tension-free mesh repair either open or laparoscopic provides excellent results with better short-term outcome and lower recurrence rate than non-mesh modified Bassini's repair.

Review of the management of recurrent inguinal hernia

Background: There is little available evidence on the optimal management of recurrent inguinal hernia, particularly if the original procedure involved the use of mesh. This study was a review of recurrent hernia repair in a district hospital, involving both laparoscopic and open procedures. Methods: The case notes of all patients who had a repair of a recurrent hernia between 1991 and 2000, inclusive, were examined; 171 procedures were included. Where known, the original repair was a nylon darn in 31%, mesh repair in 18%, and laparoscopic repair in 8%. Results: The recurrent hernia was repaired using a Lichtenstein open mesh technique in 63% and by the totally extraperitoneal (TEP) method in 22%. Complication rates were highest after emergency surgery (all had open surgery), where 71% had complications and one patient died. For elective repairs, complication rates were similar after open (13%) and TEP (8%) repairs. The duration of hospital stay was also similar (1.2 vs 1.3 days, respectively), and a single recurrence was seen in each group. Patients with recurrence after primary mesh repair were also managed by both techniques with similar results. Open re-operation for mesh failure was technically straightforward. Conclusions: Most recurrent hernias are still repaired by open techniques. There was no convincing evidence of different outcomes for open and TEP repairs in this review. Even when the original hernia repair involved the use of mesh, further open repair by an experienced surgeon is justified.

A prospective study comparing the complication rates between laparoscopic and open ventral hernia repairs

Background: Although ventral hernia repair is increasingly performed laparoscopically, complication rates with this procedure are not well characterized. For this reason, we performed a prospective study comparing early outcomes after laparoscopic and open ventral hernia repairs. Methods: We identified all the patients undergoing ventral (including incisional) hernia repair at a single tertiary care center between September 1, 1999 and July 1, 2001 (overall n = 257). To increase the homogeneity of the sample, we excluded umbilical hernia repairs, parastomal hernia repairs, nonelective procedures, procedures not involving mesh, and repairs performed concurrently with another surgical procedure. Postoperative complications (in-hospital or within 30-days) were assessed prospectively according to standardized definitions by trained nurse clinicians. Results: Of the 136 ventral hernia repairs that met the study criteria, 65 (48%) were laparoscopic repairs (including 3 conversions to open surgery) and 71 (52%) were open repairs. The patients in the laparoscopic group were more likely to have undergone a prior (failed) ventral hernia repair (40% vs 27%; p = 0.14), but other patient characteristics were similar between the two groups. Overall, fewer complications were experienced by patients undergoing laparoscopic repair (8% vs 21%; p = 0.03). The higher complication rate in the open ventral hernia repair group came from wound infections (8%) and postoperative ileus (4%), neither of which was observed in the patients who underwent laparoscopic repair. The laparoscopic group had longer operating room times (2.2 vs 1.7 h; p = 0.001), and there was a nonsignificant trend toward shorter hospital stays with laparoscopic repair (1.1 vs 1.5 days; p = 0.10). Conclusions: The patients undergoing laparoscopic repair had fewer postoperative complications than those receiving open repair. Wound infections and postoperative ileus accounted for the higher complication rates in the open ventral hernia repair group. Otherwise, these groups were very similar. Long-term studies assessing hernia recurrence rates will be required to help determine the optimal approach to ventral hernia repair. Drs.

Does resident post graduate year influence the outcomes of inguinal hernia repair?

INTRODUCTION: We evaluated the effect of the postgraduate medical education level (PGY) of surgery residents on recurrence of inguinal hernia, complications, and operative time. METHODS: Post hoc analysis was performed on prospectively collected data from a multicenter Veterans Affairs (VA) cooperative study. Men were randomly assigned to open or laparoscopic inguinal hernia repairs with mesh. Surgery residents performed repairs with designated attending surgeons present throughout all procedures. PGY level of the resident was recorded for each procedure. All patients were followed for 2 years for hernia recurrence and complications. PGY levels were grouped as follows: group I = PGY 1 and 2; group II = PGY 3; group III = PGY >/= 4; rates of recurrence, complications and mean operative time were compared. RESULTS: A total of 1983 patients underwent hernia repair. group III residents had significantly lower recurrence rates for open repairs when compared with group I (adjusted odds ratio = 0.24, 95% confidence interval [CI], 0.06, 0.997). The recurrence rate was similar among the groups for laparoscopic repair (P > 0.05) Complication rates were not different for either repair (P > 0.05). Mean operative time was significantly shorter for group III compared with group I for both open (-6.6 minutes; 95% CI, -11.7, -1.5) and laparoscopic repairs (-12.9 minutes; 95% CI, -19.8, -6.0) and between group II and group I for laparoscopic repair (-15.0; 95% CI, -24.3, -5.7). CONCLUSIONS: Despite the presence of an attending surgeon, open hernia repairs performed by junior residents were associated with higher recurrence rates than those repaired by senior residents. Lower resident level was associated with increased operative time for both open and laparoscopic repair.     

Improved outcomes with the Prolene Hernia System mesh compared with the time-honored Lichtenstein onlay mesh repair for inguinal hernia repair

BACKGROUND: Inguinal hernia repairs are commonly performed operations. Recently, Neumayer et al examined the gold standard Lichtenstein onlay mesh repair (LMR) against laparoscopic inguinal hernia repair and showed that the recurrence rates are higher for laparoscopic mesh repairs when compared with the open onlay mesh repair (laparoscopic = 10.1% versus open = 4.9%). In 1998, the Prolene Hernia System (PHS) mesh, consisting of an onlay and an underlay patch attached with a connector, was introduced as an option for tension-free open repair of inguinal hernias combining the benefits of a posterior and anterior repair from an open approach. Our objective was to evaluate the PHS mesh repair versus the LMR for inguinal hernias. We hypothesized that the recurrence rate of PHS mesh would be lower compared with the LMR with overall similar complication rates. METHODS: PHS mesh hernia repairs performed from January 2003 to July 2005 and LMR repairs from January 2000 to July 2002 were included. Demographic data such as age, race, and gender as well as comorbid conditions such as chronic obstructive pulmonary disease, congestive heart failure, previous myocardial infarction, diabetes, hypertension, prostatism, and chronic cough were collected. Complications such as cord injury, seroma, hematoma, urinary retention, urinary tract infection, orchitis, and wound infection were recorded. Recurrences in each group were also recorded. A student t test and chi-square analysis were used for statistical analysis. RESULTS: Six hundred twenty-two charts were reviewed during the 2 time periods (PHS mesh = 321, LMR = 302). The median follow-up for the study was 17 months. There was no significant difference with regards to age, race, gender, or comorbidities between the 2 groups. Overall, there was a trend toward decreased complications in the PHS mesh group compared with the LMR group (PHS mesh = 17%, LMR = 23%, P = .07), with a significant difference in the hematoma/seroma rates (PHS mesh = 6.9%, LMR = 12.6%, P = .015). Finally, there was a significant decrease in the recurrence rate for the PHS mesh group when compared with the LMR group (PHS mesh = 0.6%, LMR = 2.7%, P = .04). CONCLUSION: Our study shows, during a median follow-up of 17 months, improved outcomes by using the PHS mesh compared with the gold standard Lichtenstein onlay mesh for inguinal hernias with significantly lower recurrence rates. Additionally, in the PHS mesh group, there was a trend toward decreased overall complication rates with significantly less seroma/hematoma rates. Therefore, the PHS mesh repair may represent a superior alternative for the repair of inguinal hernias.     

Full laparoscopic incisional hernia repair using a 2-port route technique

BACKGROUND AND AIMS: The incidence of incisional hernia repair is increasing each year throughout the world. We created a full laparoscopic herniorrhaphy by means of an easy, reliable, and minimally invasive (two trocars) intraperitoneal onlay technique, using different sizes of a DualMesh (W. L. Gore & Associates; Flagstaff, AZ) with the soft side against the adherence material. METHODS: A group of patients with an incisional hernia and other ventral hernias underwent a laparoscopic herniorrhaphy using this technique. By combining simple extra- and endocorporeal manipulation, a mesh, prior to being inserted into peritoneal cavity through a trocar port was completed with four sutures between the corner of the mesh and the abdominal wall, so that when pulling the strands outside the abdomen, the furled intraperitoneal mesh being unfurled flat, was lifted from and overlapped the hernial defect at the top of the abdomen spontaneously and exactly. The mesh was anchored by nonabsorbable surtures and endo-Helical Fasteners. The sutures were either tied and the knots buried subcutaneously, or were eventually removed. RESULTS: It is by employing only two trocars applying this technique to a complete full laparoscopic intraperitoneal onlay of different sizes of a DualMesh incisional and ventral hernia repair. The mesh overlapped all hernial margins nicely and was anchored firmly. Postoperative courses were uneventful, without any complications. During the longest follow-up period of 2 years and 1 month, there was no recurrent evidence of the hernia in this group. CONCLUSIONS: This technique, which applies to almost every laparoscopic ventral hernia repair procedure for use against an adherence mesh, can help to carry out an ideal, easy, and quick orientation and intraperitoneal anchoring of the mesh.     

Retromuscular sutured incisional hernia repair: a randomized controlled trial to compare open and laparoscopic approach

To compare the early and intermediate results of the open and laparoscopic tension-free repair of incisional hernia, 24 patients were randomized prospectively to undergo laparoscopic or open repair of incisional hernia with retromuscular placement of the prosthesis using transabdominal sutures for mesh fixation. All the procedures were completed as planned. The mean duration of surgery was not significantly different between the 2 groups (P=0.15). Time to oral solid food intake was longer in the open group (P=0.002). The analgesic requirement was lower in the laparoscopic group (P=0.05). One patient after open surgery and 2 in the laparoscopic group suffered postoperative complications (P=0.71). Postoperative stay was shorter in the laparoscopic group (P=0.006). No readmission or recurrence was registered within 6 months from surgery in either group. Laparoscopic incisional hernia repair, based on the Rives-Stoppa technique, is a safe, feasible alternative to open techniques. However, larger studies and long-term follow-up are required to further evaluate the true effectiveness of this operation.     

Mesh repair of incisional hernia: comparison of laparoscopic and open repair.

OBJECTIVE: To compare our results of open and laparoscopic mesh repair of incisional hernias. DESIGN: Retrospective cohort study. SETTING: Teaching hospitals, The Netherlands. SUBJECTS: All patients who had had a laparoscopic (n = 25) or an open (n = 76) mesh repair of incisional hernia between January 1996 and January 2000. INTERVENTIONS: Physical examination at the time of the study. MAIN OUTCOME MEASURES: Morbidity and recurrence. RESULTS: The groups were comparable. 11 patients (14%) developed postoperative infections after open repair and 1 (4%) after laparoscopic repair (p = 0.29). Median hospital stay was 5 days (range 1-19) in the open group and 4 (range 1-11) in the laparoscopic group (p = 0.28). The 2-year cumulative incidence of recurrence was 18% after open repair (median follow-up of 17 months (range 1-46) and 15% after laparoscopic repair (median follow-up of 15 months, range 1-44). Recurrences in the laparoscopic group were all among the first 7 cases in which the mesh was fixed with staples alone. CONCLUSION: There were fewer infections and hospital stay was shorter in the laparoscopic group, but not significantly so. Recurrence rates were comparable.     

Umbilical hernia in adults

Background: There is no consensus on the best technique for the repair of umbilical hernia in adults. The role of laparoscopic hernioplasty of umbilical hernia remains controversial. This study was undertaken to compare the outcomes of open and laparoscopic onlay patch repair of umbilical hernia in adults. Methods: From January 1996 to December 2002, 102 patients underwent elective repair of umbilical hernia. Operative techniques included Mayo repair (n = 43), laparoscopic onlay Gore-Tex patch hernioplasty (n = 26), suture herniorrhaphy (n = 24), and mesh hernioplasty (n = 9). Results: Demographic features and risk factors were similar among the four groups. The operative time of laparoscopic hernioplasty (median, 66 min) was significantly longer than those for patients who underwent Mayo repair (60 min) or sutured herniorrhaphy (50 min) (p < 0.05). None of the patients who underwent laparoscopic patch repairs required conversion to open repair. The median pain score at rest on postoperative day 1 was significantly lower in patients who underwent laparoscopic repair compared to those who had Mayo repair. A significantly shorter hospital stay and a lower wound morbidity rate were also observed in patients who underwent laparoscopic repair. With a mean follow-up of 2 years, suture herniorrhaphy had a relatively high recurrence rate (8.7%), whereas no recurrence was documented for the other techniques. Conclusions: Laparoscopic onlay patch hernioplasty is a safe and efficacious technique for the repair of umbilical hernia. Compared to Mayo repair, the laparoscopic approach confers the advantages of reduced postoperative pain, shorter hospital stay, and a diminished morbidity rate.     

Parastomale Hernienversorgung mit prothetischer Netzplastik

After stoma formation, parastomal hernia develops in 30–50% of patients, with one-third of these require operative correction. Recurrence rates are very high after suture repair of parastomal hernias or relocation of the stoma. Open or laparoscopic mesh repairs have resulted in much lower recurrence rates. Long-term follow-up of the various techniques for parastomal hernia repair is lacking, as are randomized trials. A prophylactic prosthetic mesh placed in a sublay position at the index operation has reduced the rate of parastomal hernia in randomized trials. A prophylactic mesh in an onlay position, a sublay position, and an intraperitoneal onlay position has also been associated with low herniation rates in non-randomized studies. Although several questions within this field still have to be answered, it seems obvious that use of a mesh represents a suitable measure for the prevention of parastomal hernia as well as parastomal hernia repair.     

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.     

Simultaneous extraperitoneal laparoscopic radical prostatectomy and intraperitoneal inguinal hernia repair with mesh.

OBJECTIVE: This report depicts the feasibility of the concomitant repair of a large direct inguinal hernia with mesh by using the intraperitoneal onlay approach after extraperitoneal laparoscopic radical prostatectomy. METHODS: A 66-year-old man with localized adenocarcinoma of the prostate was referred for laparoscopic radical prostatectomy. The patient also had a 4-cm right, direct inguinal hernia, found on physical examination. To minimize the risk of infection of the mesh, an extraperitoneal laparoscopic prostatectomy was performed in the standard fashion after which transperitoneal access was obtained for the hernia repair. The hernia repair was completed by reduction of the hernia sac, followed by prosthetic mesh onlay. In this fashion, the peritoneum separated the prostatectomy space from the mesh. A single preoperative and postoperative dose of cefazolin was administered. RESULTS: The procedure was completed with no difficulty. Total operative time was 4.5 hours with an estimated blood loss of 450 mL. The final pathology revealed pT2cN0M0 prostate cancer with negative margins. No infectious or bowel complications occurred. At 10-month follow-up, no evidence existed of recurrence of prostate cancer or the hernia. CONCLUSION: Concomitant intraperitoneal laparoscopic mesh hernia repair and extraperitoneal laparoscopic prostatectomy are feasible. This can decrease the risk of potential infectious complications by separating the mesh from the space of Retzius where the prostatectomy is performed and the lower urinary tract is opened.

Short-term outcomes of laparoscopic and open ventral hernia repair: a meta-analysis

BACKGROUND: Although laparoscopic repair of ventral hernia has become increasingly popular, its outcomes relative to open repair have not been well characterized. For this reason, we performed a meta-analysis of studies comparing open and laparoscopic ventral (including incisional) hernia repair. HYPOTHESIS: Laparoscopic ventral hernia repair results in better short-term outcomes than open ventral hernia repair. DATA SOURCES: Structured MEDLINE search for published studies. One unpublished study was also identified. STUDY SELECTION: Studies were selected on the basis of study design (comparison of laparoscopic and open ventral hernia repair). The 3 main outcome measures were perioperative complications, operative time, and length of hospital stay. Of 83 potential studies identified by abstract review, 8 (10%) met the inclusion criteria. DATA EXTRACTION: Two reviewers assessed each article to determine eligibility for inclusion and, where appropriate, abstracted information on patient characteristics and main outcome measures. DATA SYNTHESIS: Across 8 studies, 390 patients underwent open repair and 322 underwent laparoscopic repair. Perioperative complications were less than half as likely to occur in patients undergoing laparoscopic repair (14% vs 27%; P =.03; odds ratio, 0.42; 95% confidence interval, 0.29-0.68). Average length of stay was shorter in the laparoscopic group (2.0 vs 4.0 days; P =.02). No statistically significant difference in operative times was noted between laparoscopic and open repair (99 vs 96 minutes; P =.38). CONCLUSIONS: Laparoscopic ventral hernia repair offers lower complication rates and shorter length of stay than open repair. However, randomized controlled trials and studies with long-term follow-up are needed to confirm these findings and to assess long-term rates of hernia recurrence.     

Laparoscopic mesh repair of incisional hernia: an alternative to the conventional open repair?

Background Tension-free incisional hernia repair using alloplastic material increasingly replaces conventional repair techniques. This change resulted in a decreased recurrence rate (50% vs. 10%, respectively). Recently, laparoscopic approaches for the intraperitoneal tension-free mesh application have been introduced. The decreased trauma at the incision site and the reduction in wound infections appear to be the main advantages. The aim of the present study was to evaluate the early and long-term complications as well as patients’ contentment. Methods Laparoscopic hernia repair with intraperitoneal polytetrafluroethylene (PTFE) mesh implantation was performed on 62 patients at the Klinikum Grosshadern between 2000 and 2005 (29 males, 33 females age 60.7). Intra- and postoperative complications were registered prospectively and retrospectively analyzed. In addition, 57 patients were evaluated for recurrence, postoperative pain and patient contentment (median follow-up 409 days). Results A low complication rate was observed in our patient collective. One trocar bleeding occurred. Three patients presented with wound hematoma. The recurrence rate was 8% (2/25). Sixty-two percent of the patients were free of complaints postoperatively. Eighty-five percent would once again choose the laparoscopic approach for incisional hernia repair. Conclusion The laparoscopic technique was associated with a low recurrence rate, a small rate of wound infections and high patient comfort. Thus, the laparoscopic approach for mesh implantation appears to be a safe and effective method for the treatment of incisional hernias. The efficiency for laparoscopic intraperitoneal mesh implantation, however, should be further evaluated within a prospectively randomized multicenter trial. M. Stickel and M. Rentsch contributed equally.     

Repair of giant incisional abdominal wall hernias using open intraperitoneal mesh

Background Very large and complex incisional hernias, especially those involving loss of abdominal wall, present a particular challenge to the surgeon. Aims The open intraperitoneal technique was used prospectively for the repair of incisional hernias in a selected group of patients with large defects, often those with major loss of abdominal wall, overweight patients, and previous failures of incisional repair. Materials and methods Between 1 January 1999 and 31 December 2005, out of 275 patients operated on for incisional hernia repair, 61 of them, most of whom were obese with multiorificial recurrent or giant hernias and contraindicated for laparoscopy, were treated using an open intraperitoneal mesh technique. There were 50 females and 11 males, with a mean age of 61. The median ASA score of the group was 2.3, with a mean BMI of 34 kg/m² and a mean hernia surface of 182 cm². Sixty-four percent of the patients had undergone one or more previous incisional hernia repairs. Results Mean operating time was 130 min, with an average hospital stay of 13 days. None of the patients died. Postoperative complications occurred in 21% of the patients; most of which were minor, but two cases (3.3%) developed deep abscesses requiring surgery and removal of the mesh. A recurrence rate of 5% was found after a mean follow-up of 35 months (8–88). Conclusion Open intraperitoneal mesh repair appears to be a good option for the treatment of complex incisional hernia (at least 10 cm in diameter or multiorificial) in obese patients contraindicated for laparoscopy.
