PurposeParastomal hernia is a common late complication after stoma creation. The management options are many; unfortunately, most literature suggests unsatisfactory results. There are few studies comparing the outcomes after repair of parastomal hernias especially in recurrent cases, and the results are controversial. The aim of this study was to compare outcomes after repair of recurrent parastomal hernias between direct repair (DR) and relocation (RL).MethodWe performed a retrospective chart review of patients who underwent direct repair or RL for recurrent parastomal hernia during the period between 1990 and 2005. Perioperative data and re-recurrence rates were obtained and analysed with appropriate statistical methods.ResultsWith mean follow-up time of 2 years, 50 operations were available for evaluation; 27 (54%) DR and 23 (46%) RL [five same-side RL (SSRL) and 18 opposite-side RL (OSRL)]. There were no deaths and there were similar complication rates between groups. Four of five (80%) SSRL had a re-recurrent parastomal hernia. Considering only DR with OSRL, although OSRL had longer operative time and hospital stay than DR, the re-recurrence rate was lower (38%vs 74%; P = 0.02). However, with Kaplan–Meier calculated and longer predicted follow-up time, re-recurrence rates were similar (Log rank P = 0.09).ConclusionRecurrent parastomal hernia repair is associated with high re-recurrence rates.OSRL seems to have promising short-term outcomes; however, whether these results hold up long-term remains unclear. Therefore, larger cohorts of patients with longer follow-up or prospective randomized trials are needed.
