Sac ligation in XXXX : A meta-analysis of randomized controlled trials.

@entity1 @entity260 @entity158 @entity547 @entity169 @entity282
BACKGROUND: Traditionally, @entity547 during @entity169 is considered mandatory to prevent postoperative development of @entity547 . However, ligation may induce @entity282 . The aim of this study was to evaluate the outcomes of @entity547 after @entity169 . METHODS: We conducted a systematic review and meta-analysis of randomized controlled trials to investigate the outcomes of @entity547 for open or laparoscopic @entity169 . Incidence of @entity547 was assessed following the surgery. The secondary outcomes included @entity282 . RESULTS: Five trials were selected and their results were summarized. These 5 trials were published between 1984 and 2014, and the sample sizes ranged from 50 to 467 @entity1 . Four trials had recruited @entity1 with @entity169 who underwent open repair, and one study enrolled @entity1 who underwent laparoscopic procedures. We observed no difference in the incidence of @entity547 and @entity260 between the sac ligation and nonligation groups. Postoperatively, the intensity of @entity158 was significantly higher in the ligation group than in the nonligation group at Day 7 (Weight mean difference 1.46; 95% confident interval: 0.98-1.95). CONCLUSION: Hernia sac ligation was associated with higher @entity282 , and did not show any benefit over sac nonligation regarding the incidence of recurrence and @entity260 in @entity1 undergoing open tension-free mesh repair or laparoscopic procedures.
