Polyglactine/polypropylene mesh vs. propylene mesh: is there a need for newer prosthesis in inguinal hernia?

BACKGROUND/AIM: To compare outcomes of light and heavy weight mesh for repair of inguinal hernia.

MATERIALS AND METHODS

This study was conducted at the Department of Surgery; Lady Reading Hospital, Peshawar from January 1, 2007 to December 31, 2008. Patients were divided into two groups based on the type of mesh implanted for inguinal hernia repair. Group 1 included patients in whom light weight composite (VyproII ) mesh is implanted: Group 2 included patients in whom polypropylene (Prolene R ) mesh is implanted. Data concerning the complications and post operative pain in the perioperative and postoperative period were collected and analyzed. Categorical data were presented as percentages with 95% confidence intervals and compared using a chi2 test and P 0.05 were considered significant.

RESULTS

Following allocation and exclusion of violating cases, 111 patients in group 1 and 138 patients in group 2 were analyzed. The mean age in group 1 was 38.20 +/- 13.34 years and in group 2 was 39.55 +/- 13.70 (P = 0.434). In group 1, hematoma formation was observed in four cases (3.6%), while it was observed in six cases (4.2%) in group 2 (P = 0.766). During the entire study, ten patients in all developed urinary retention, three of which required transient catheterization. One year post operation, there was a recurrence in only five cases overall, while only two patients complained of pain (P = 0.826).

CONCLUSION

The frequency of postoperative pain and complications in patients was similar in both groups.
