title: The management of colorectal perforation and peritonitis.
abstract: BACKGROUND
  Surgical outcomes in patients presenting with colonic perforation or peritonitis tend to be poor. This study was undertaken to determine outcomes in such patients at a time before multiple re-laparotomies were performed.
  
  
  METHODS
  Retrospective analysis of computer records of all patients presenting acutely to the University Surgical Unit (Wellington School of Medicine) with colonic perforation or peritonitis over a 15-year period.
  
  
  RESULTS
  Seventy-three patients, 33 males and 40 females were admitted with either perforation or localized peritonitis of colorectal origin. Of these, 78% were managed as emergencies, but six were admitted electively and found incidentally. Consultant surgeons performed surgery slightly more frequently than registrars. Two patients were managed non-operatively. Forty-one per cent received peri-operative blood transfusion and 22% peri-operative total parenteral nutrition. The majority of patients presented with either peritonitis or free perforation in association with diverticular disease. The site of perforation was either ileocolic or sigmoid colonic in the majority of patients. Hartmann's operation was the most commonly performed resection. Respiratory, urinary and wound infections were the most commonly observed postoperative complications. Two patients developed anastomotic leaks (6.3%). The overall persistent intra-abdominal infection rate was 5.5%. Seven patients died following surgery.
  
  
  CONCLUSIONS
  Resection of the perforated bowel is mandatory and this should be followed by anastomoses in the case of right-sided lesions and a Hartmann's operation or resection, colostomy and mucous fistula in distally situated lesions.
