Multiple laparotomies for severe intra-abdominal infection

Abstract

Background: Mortality rates for patients with severe peritoneal infection are high. The present study was undertaken in order to examine mortality rates in patients with severe peritoneal infection who were managed by planned re-laparotomy.

Methods: Retrospective analysis of patients presenting at the King Faisal Specialist Hospital and Research Centre between 1992 and 1994 with severe peritoneal infection was undertaken.

Results: A total of 52 patients underwent either single (n = 30) or multiple (n = 22) peritoneal lavage, and Acute Physiology and Chronic Health Evaluation (APACHE II) scores and predicted mortality rates were calculated for these patients. The predicted mortality rate for patients undergoing a single washout was 42.4%, actual mortality: 23%. The predicted mortality for patients undergoing multiple washouts was 55.6%, actual mortality: 36.3%. No patient with a predicted mortality of < 30% who underwent multiple washouts died. Of nine patients with a predicted mortality between 31 and 60%, one died (11.1%). For a predicted mortality of 61-80%, five of six patients died (83.3%), and for patients with a predicted mortality of > 80%, two of three died (66.7%).

Conclusions: The utilization of planned re-look laparotomy and peritoneal lavage in patients with severe peritonitis may result in a significant decrease in mortality as predicted by APACHE II scoring.
