Urgent Redo-Laparotomies: Patterns and Outcome-A Single Centre Experience.

A proportion of the operations performed in a surgical gastroenterology department are unplanned repeat laparotomies for complications of the original procedure. We examined why, in our department, these 'redo' laparotomies were performed and what was their outcome. We retrospectively analyzed 6530 patients operated between September 1996 - December 2010, of these 257 redo laparotomies were performed in 193(2.5 %) patients. There were 138 males and 55 females who had a mean age of 42 years (range 7-68 years). Eighty one (42 %) of the index surgeries were elective and 112 (58 %) performed in the emergency situation. Pancreas was the commonest organ for the index operation {50 (25.9 %)}, followed by the colon and rectum {45 (23.3 %)} and the small bowel {36 (18.7 %)}. Postoperative bleeding was the most common cause for re-exploration 66 (34.2 %) followed by an abscess or fluid collection that required surgical drainage 57 (29.6 %). The mortality rate after redo laparotomies was 33.2 % with sepsis and multi-organ failure being the commonest cause of death. Urgent redo-laparotomies that are performed following complicated abdominal operations have a high mortality rate. Postoperative bleeding, intrabdominal abscess and peritonitis are the commonest cause for redo-laparotomy. Multiple redolaparotomies and associated co-morbid conditions are significant predictors of mortality.
