title: Primary colorectal anastomosis with the intracolonic bypass tube.
abstract: BACKGROUND
  Intracolonic bypass with primary colocolonic or colorectal anastomosis may be an effective option in the operative management of complicated colonic disease when adequate bowel preparation is not possible. A pliable latex tube is anchored to mucosa and submucosa 3 centimeters proximal to a site of colocolonic anastomosis and later spontaneously evacuated by way of the rectum.
  
  
  METHODS
  Twenty-nine consecutive patents who required urgent colorectal operations in the presence of unprepared bowel underwent left colon resection with intracolonic bypass and primary anastomosis. These patients would have otherwise undergone multistage procedures for the management of the colorectal disorders. Demographic data, APACHE II scores, and type and frequency of complications were recorded.
  
  
  RESULTS
  Between July 1, 1990, and June 30, 1991, 31 patients were eligible for entry in the study. Two patients ultimately had contraindications for the use of intracolonic bypass. The causes encountered included complicated diverticular disease, colonic carcinoma, sigmoid volvulus, and iatrogenic colorectal injury. Complications included wound infection (7), myocardial infarction (2), prolonged ileus (1), deep vein thrombosis (2), and anastomotic leak (2). Postoperative myocardial infarction and subsequent multiorgan system failure were responsible for the only death in this study.
  
  
  CONCLUSIONS
  Intracolonic bypass permits a safe primary anastomosis where multistage procedures would otherwise be required. Avoidance of colostomy and the attendant socioeconomic benefits warrants further study of this method.
