BackgroundIn Edinburgh a group of surgeons agreed to convert to a lightweight, composite mesh (Ultrapro-Ethicon) for totally extraperitoneal (TEP) inguinal hernia surgery. The aim of this study was to compare the outcome following the use of a new lightweight vs a standard heavyweight mesh during TEP hernia repair.MethodsPatients undergoing TEP using lightweight (LWM) or heavyweight meshes (HWM) between March 2004 and March 2006 were identified from the Lothian Surgical Audit database. The patients who re-presented with recurrence of hernia were studied in greater detail. Date of re-attendance at a clinic with recurrence was used as a surrogate for date of recurrence.ResultsTwo hundred and fifty one patients had 371 hernia repairs with LWM. A total of 16 (4.3%) recurred with a median follow-up of 14.5 months. A concurrent group of 326 patients had 425 repairs with standard mesh and have had 12 (2.82%) recurrences with a median follow-up of 22.4 months. A group of patients operated immediately prior to the introduction of LWM consisted of 328 patients who had 436 repairs using HWM, of whom 13 (2.98%) have recurred with a median follow-up of 43 months. Whilst there are no statistically significant differences in recurrence rates between these groups, we are concerned that the LWM group has the highest recurrence rate despite the shortest follow-up.ConclusionIn view of increased patient comfort, we continue to recommend LWM for laparoscopic inguinal hernia surgery but would recommend that, in larger hernias and possibly for all, the surgeon should improve mesh adhesion.
