The repair of large and/or recurrent ventral hernias is associated with significant complications and a recurrence rate that can be more than 50 per cent. Laparoscopic ventral herniorrhaphy, a recent development, has been shown to be safe and effective in the repair of ventral hernias. This study retrospectively reviews all ventral hernia repairs over a 3-year period, November 1995 through December 1998, at a community-based teaching hospital. The purpose of the study was to compare open and laparoscopic repairs. A total of 253 ventral hernia repairs were performed during this time, 174 open and 79 laparoscopic. The age, weight, and sex distribution was similar for each group. The hernias in the open group averaged 34.1 cm2 in size, and mesh used averaged 47.3 cm2. In the laparoscopic group, the hernia defect averaged 73.0 cm2, and the mesh size averaged 287.4 cm2. Operative time was longer in the open group, 82.0 versus 58.0 minutes. In the open group, there were 38 (21.8%) minor and 8 (4.6%) major complications, compared with 13 (16.5%) minor and 2 (2.5%) major complications in the laparoscopic group. Hospital stay was shorter for the laparoscopic group, 1.7 versus 2.8 days. At an average follow-up of 21 months (range, 2-40 months), there have been 36 recurrences in the open group (20.7%) compared with 2 recurrences in the laparoscopic group (2.5%). In this series, laparoscopic ventral herniorrhaphy compares favorably to open ventral herniorrhaphy with respect to wound complications, hospital stay, operative time, and recurrence rate.
"The laparoscopic approach is now fast becoming an established technique in the repair of most types of hernia. This present meta-analysis has shown that there is significant benefit with laparoscopic repair with regard to recurrence rates, operative time and reduced post-operative wound complication compared to the open repair of hernias. "
[Show abstract][Hide abstract] ABSTRACT: The purpose of this study is to compare the difference of incidence of post-operative complications, operative time, length of stay and recurrence of patients undergoing laparoscopic or open repair of their ventral/incisional hernia a meta-analytic technique for observational studies.
A literature search was performed using Medline, PubMed, Embase and Cochrane databases for studies reported between 1998 and 2009 comparing laparoscopic and open surgery for the treatment of ventral (incisional) hernia. This meta-analysis of all the observational studies compared the post-operative complications recurrence rate and length of stay. The random effects model was used. Sensitivity and heterogeneity were analysed.
Analysis of 15 observational studies comprising 2452 patients qualified for meta-analysis according to the study's inclusion criteria. Laparoscopic surgery was attempted in 1067 out of 2452. The results showed that the length of stay (odds ratio [OR], - 1.00; 95% confidence interval [CI], - 1.09 to - 0.91; P < 0.00001) and operative time (OR, 59.33; 95% CI, 58.55 to 60.11; P < 0.00001) was significantly lower in the laparoscopic group. The results also showed that there was a significant reduction in the formation of abscesses (OR, 0.38; 95% CI, 0.16 to 0.92; P = 0.03) and wound infections (OR, 0.49; 95% CI, 0.29 to 0.82; P = 0.007) post-operatively. There is a trend which indicates that the recurrence of the hernia using laparoscopic repair versus open repair was overall lower with the laparoscopic repair (OR, 0.48; 95% CI, 0.22 to 1.04; P = 0.06), however, this was not significant.
Laparoscopic incisional hernia repair was associated with a reduced length of stay, operative time and lower incidence of abscess and wound infection post-operatively. This study also highlights the benefit of using observational studies as a form of research and its value as a tool in answering questions where large sample sizes of patient groups would be impossible to accumulate in a reasonable length of time.

"The technique offers several advantages over conventional open techniques performed with or without mesh. It allows broad exposure of the hernia and definition of the hernia margins, has a reduced risk of infection due to its less invasive character and surgical intervention can be performed immediately because the incisional portals are away from the defect and surrounding oedematous tissue (Park et al. 1996, 1998; Ramshaw et al. 1999; Berger et al. 2002). Conversion to an open technique is always optional, for example in those cases where reduction with atraumatic bowel grasping forceps is difficult due to the length of herniated intestine. "
"The extremely low rate of wound infection and recurrence are among the most important advantages of the laparoscopic approach. Because the prosthetic mesh is placed intraabdominally, many surgeons use expanded polytetrafluoroethylene (ePTFE) grafts because of the low adhesive potential.2–4,6,7 High cost, inferior handling characteristics, and poor incorporation into the tissues are among the drawbacks of ePTFE mesh. "
[Show abstract][Hide abstract] ABSTRACT: Laparoscopic repair of ventral incisional hernias is feasible and safe. Polypropylene mesh is often preferred because of its ease of handling and lower cost. Complications like adhesion and fistula formation can occur. The goal of this study was to determine whether bowel adhesions and their attendant complications could be prevented by interposition of omentum.
Thirty patients underwent laparoscopic ventral incisional hernias repair with polypropylene mesh. Omentum was always positioned over the loops of bowel for protection. At a mean follow-up of 14 months, 20 patients underwent ultrasonic examination using the previously described visceral slide technique to detect adhesions.
The mean size of the hernias in the study was 50.3 cm2, and the mean size of the mesh applied was 275 cm2. Thirteen patents (65%) had no sonographically detectable adhesions. Five patients demonstrated adhesions between the mesh and omentum, 1 patient developed adhesions between the left lobe of the liver and the mesh, and only 1 case of bowel adhesion to the edge of the mesh was found.
Laparoscopic ventral incisional hernias repair with polypropylene mesh and omental interposition is not associated with visceral adhesions in the majority of patients. Polypropylene mesh can be used safely when adequate omental coverage is available.
