Retrospective observational study on the incidence of XXXX after reversal of a temporary diverting ileostomy following rectal carcinoma resection with follow-up CT scans.

BACKGROUND: Wounds resulting from the closure of temporary stomas have a high risk of developing an @entity547 ( @entity547 ) with incidences around 30  % in studies designed to investigate this outcome. A @entity346 ( @entity346 ) is often used in @entity1 after low anterior resection (LAR) for @entity5 . METHODS: The @entity6497 study is a retrospective cohort study of @entity5 @entity1 who had a LAR with a reversed @entity346 and at least one CT scan during follow-up. Two radiologists independently evaluated all abdominal CT scans to diagnose @entity547 at the ileostomy wound and additionally, @entity547 at the laparotomy site. RESULTS: From the oncological database of @entity5 @entity1 treated from 2003 till 2012 (n  =  317) a cohort of 153 @entity1 that fulfilled the inclusion criteria was identified. @entity5 resection was performed by laparoscopy in 53 @entity1 (34.6  %) and by laparotomy in 100 @entity1 (65.4  %). A total of 17 @entity547 (11.1  %) was diagnosed at the former stoma site after a mean follow-up of 2.6  years. Of these, 8 @entity547 were in @entity1 who had a laparoscopic LAR (15.1  %) and 9 @entity547 in @entity1 who had an open LAR (9.0  %) (Fisher's exact test; p  =  0.28). @entity547 on the other abdominal wall incisions was reported in 69 @entity1 (45.1  %). Of these, 10 @entity1 underwent laparoscopic rectal surgery (18.9  %) and in 59 @entity1 had open rectal surgery (59.0  %) (Fisher's exact test; p  <  0.0001). CONCLUSION: We found a lower number of @entity547 (11.1  %) after reversal of ileostomies than expected from the literature. In contrast to the findings at the ileostomy site, a very high frequency of @entity547 (59.0  %) after LAR by laparotomy was found, which was significantly higher than after laparoscopic LAR.
