title: Atypical diverticular disease: surgical results.
abstract: OBJECTIVE
  Patients with diverticular disease may present with chronic symptoms but never develop diverticulitis. The purpose of this research was to review the outcome of surgical intervention in this subgroup of patients with atypical "smoldering" diverticular disease.
  
  
  METHODS
  Records of 930 patients who underwent sigmoid resection for diverticular disease during a ten-year period at the Mayo Clinic in Rochester, Minnesota, were reviewed. Forty-seven patients (5 percent) fit our inclusion criteria for smoldering diverticular disease and underwent sigmoid colectomy with primary anastomosis. A minimum of 12 months of follow-up was completed in 68 percent of these patients.
  
  
  RESULTS
  Evidence of acute or chronic inflammatory changes was present in 76 percent of resected specimens. Complete resolution of symptoms occurred in 76.5 percent, with 88 percent being pain free.
  
  
  CONCLUSIONS
  We conclude that the diagnosis and presentation of atypical smoldering diverticular disease is an uncommon and poorly defined entity. However, sigmoid resection in this subgroup of patients is safe and is associated with resolution of symptoms in the majority of cases.
