title: Critical appraisal on the role and outcome of emergency colectomy for uncomplicated right-sided colonic diverticulitis.
abstract: BACKGROUND
  Emergency colectomy is well accepted for treating complicated right-sided colonic diverticulitis. However, the role of colectomy for uncomplicated diverticulitis is not well defined. The aim of this study was to evaluate the short-term and long-term surgical outcome of uncomplicated right-sided diverticulitis in our locality.
  
  
  METHODS
  Retrospective chart review of patients operated for right-sided diverticulitis over a 20-year period was conducted. Recurrent attacks of right-sided diverticulitis, re-operation rate and re-hospitalisation rate were the long-term parameters of interest. An updated telephone interview was carried out for all surviving patients.
  
  
  RESULTS
  Seventy-four patients (35 males and 39 females), median age 35.5 (range 16-70) years, were operated for uncomplicated diverticulitis. Thirty patients underwent colectomy, whereas the others underwent appendectomy with diverticulectomy (n = 8) or appendectomy alone (n = 36). All short-term parameters were less favourable for the colectomy group, including higher complication rate, slower return of gastrointestinal function, higher requirement of parenteral analgesic and longer hospital stay. Without colectomy, only 2 patients developed recurrent diverticulitis necessitating hospitalisation, both of whom resolved on conservative treatment. On the other hand, 1 patient required re-operation after colectomy because of intestinal obstruction. The overall re-hospitalisation rate was comparable between the colectomy and the non-colectomy group (16.7% vs. 13.6%).
  
  
  CONCLUSIONS
  Emergency colectomy can eradicate suspicious lesions and eliminate risk of recurrent diverticulitis but at the expense of higher morbidity rates. As the natural course of uncomplicated right-sided colonic diverticulitis is usually benign, conservative treatment with minimal surgery may be a better therapeutic option.
