Relaparotomy: a five-year review of indications and outcome

Abstract

Complications from abdominal surgery may necessitate reoperation and can be associated with significant morbidity and mortality. This review aims to analyse the incidence and outcome of relaparotomy for various indications. In a retrospective review of case notes of patients who had undergone one or more relaparotomies during the same hospitalisation between 1996 and 2000, 55 patients required relaparotomy. Indications included bleeding, infection, anastomotic leakage, wound dehiscence, necrotising pancreatitis, bowel necrosis, bowel obstruction and miscellaneous indications. Relaparotomy for dehiscence and obstruction carried minimal risk; for bleeding and infection entailed moderate risks; and for anastomotic leak had the highest mortality rate. The mortality rate increased in older age groups, multiple system and organ failure and multiple relaparotomies. The overall mortality rate was 38%. Twenty-nine per cent of patients had MRSA infection contributing to sepsis and multiple system and organ failure. Reintervention had brought to evidence technical errors, which could be corrected, and resulted in patient salvage in some cases. The mortality rate of relaparotomy has remained unchanged compared with data published previously, despite improvements in surgical techniques and critical care. Timely relaparotomy is valuable in the identification and treatment of complications following abdominal surgery.
