Redo-laparotomies: reasons, morbidity and outcome

A large number of patients undergo various operative procedures every day and laparotomy forms a large proportion. At times, laparotomies have to be redone due to complications like biliary peritonitis, faecal fistula, burst abdomen or anastomotic leak. Our objectives were to determine the causes of Redo-laparotomy evaluate morbidity associated with it and analyze its outcome. A prospective study of patients in BP Koirala Institute of Health Sciences (BPKIHS) from 1. 1. 2009 to 31. 12. 2009 was done. Institutional ethical clearance was taken. The Statistical analyses were done using SPSS version 11.5. Redo-laparotomy was performed in 40(1.99%) cases. The mean age was 31.99 +/- 21.49 years with a M: F ratio of 4:3. The indications of Redo-laparotomy were: burst abdomen (n = 9; 22.5%), followed by intra-abdominal collection and abscess (n = 7; 17.5%), fecal (n = 6; 15%), and biliary peritonitis (n = 5; 12.5%). The mean duration between first laparotomy and Redo was 9.42 +/- 7.56 days and the mean duration of hospitalization was 26.98 +/- 12.50 days. Lower gastrointestinal surgeries usually lead to a Redo. The mortality in our study was 30% and 21/40 patients had to be managed in the intensive care unit. Clinical acumen formed the basis (87.5%) to decide for Redo-laparotomy in the majority. Redo-laparotomies that are performed following complicated abdominal surgeries have high morbidity and mortality rates. Multiple factors may lead to a Redo-laparotomy which is beyond the hands of a clinician yet a vigilant and vigorous management could help reduce the rate of Redo-laparotomies.
