One-stage resection without colonic lavage in emergency surgery of the left colon.

Intra-operative colonic lavage is a widespread procedure introduced to decompress and clean the colon of its faecal load during emergency surgery of the left colon in order to perform a safe anastomosis. This type of lavage is never performed at our institution. The aim of this study was to evaluate the safety and acceptability of emergency left-sided colectomy without colonic lavage in a consecutive series of patients admitted at our department for perforation and obstruction of the left colon.All 44 patients (29 with obstruction and 15 with perforation) on whom a one-stage left-sided colon resection was performed without colonic lavage between January 1998 and June 2004 were evaluated in a retrospective review. During this period all patients with acute disease of the left colon underwent a one stage resection without colonic lavage. The only exclusion criteria for anastomosis were: haemodynamic instability, ASA > 3, unresectable tumour. Death, anastomotic leakage and wound infection were main outcome measures.The leak rate was 4.5% and mortality 2.3% due to one case of postoperative myocardial infarction. A 16% morbidity rate was recorded due to 4 wound infections and 3 minor complications.The procedure is safe. The low morbidity and mortality of one stage resection without colonic lavage can justify future prospective studies enrolling a large number of patients to compare its results with those obtained by one stage resection with colonic lavage.
