title: Planned relaparotomy vs relaparotomy on demand in the treatment of intra-abdominal infections. The Peritonitis Study Group of the Surgical Infection Society-Europe.
abstract: OBJECTIVE
  To define the role of planned relaparotomy (PR) in the treatment of intraperitoneal infection, compared with that of relaparotomy on demand (RD).
  
  
  METHODS
  Case-control study on the basis of a prospective multicenter cohort analytic study. Statistical evaluation was done by the McNemar test for qualitative data and the Wilcoxon matched-pairs signed rank test for qualitative data.
  
  
  METHODS
  Eighteen hospitals of different care levels in Austria, Germany, and Switzerland.
  
  
  METHODS
  Thirty-eight of 42 patients with intra-abdominal infections who underwent PR were matched for APACHE II (Acute Physiology and Chronic Health Evaluation II) score, age, cause of infection, site of origin of peritonitis, and the ability of the surgeon to securely eliminate the source of infection with 38 patients taken from a cohort of 278 undergoing RD.
  
  
  METHODS
  Planned relaparotomy was defined as at least one relaparotomy decided on at the time of the first surgical intervention; RD, relaparotomy indicated by clinical findings.
  
  
  METHODS
  Mortality and incidence of postoperative multiple organ failure and infectious complications.
  
  
  RESULTS
  There was no significant difference in mortality between patients treated with PR (21%) or RD (13%). Postoperative multiple organ failure as defined by a Goris score of more than 5 was more frequent in the group of patients undergoing PR (50%), compared with the group undergoing RD (24%) (P = .01), as were infectious complications (68% vs 39% [P = .01]). Infectious complications were due to more frequent suture leaks (16% vs 0% [P = .05]), recurrent intra-abdominal sepsis (16% vs 0% [P = .05]), and septecemia (45% vs 18% [P = .05]) in the PR vs the RD groups. The incidence of other complications was not different in the two groups.
  
  
  CONCLUSIONS
  Until larger prospective studies are available, the indication for PR should be evaluated with caution.
