title: Diverticulitis of the caecum and ascending colon: an unavoidable diagnostic pitfall?
abstract: OBJECTIVE
  The infrequency of right-sided colonic diverticulitis prompted this presentation of our experiences, with emphasis on the diagnostic aspects.
  
  
  METHODS
  Charts and documentation regarding 20 patients who underwent surgery for diverticulitis of the caecum and/or ascending colon over 22 years were reviewed.
  
  
  RESULTS
  Eleven patients underwent pre-operative instrumental examinations: right-sided diverticulitis was recognized in five patients (two by barium enema, two by both ultrasonography and computerized tomography, one by all three examinations) and was suspected in another four. All diagnoses on merely clinical grounds--acute appendicitis in 10 patients and perforated peptic ulcer in one--were erroneous. Surgery consisted of 13 right standard or limited hemicolectomies, six conservative procedures and one Mickulicz' operation and subsequent right hemicolectomy. No operative deaths or long-term failures were reported.
  
  
  CONCLUSIONS
  In the presence of clinical features atypical of acute appendicitis, right-sided colonic diverticulitis should be taken into account; pre-operative instrumental examinations might increase diagnostic accuracy, thereby leading to a more correct therapeutic approach.
