Colonoscopists sometimes encounter diverticular inflammation in patients without clinical evidence of acute diverticulitis.
In this study, researchers from Indiana, USA, described the spectrum and prevalence of such endoscopic findings in patients undergoing colonoscopy.

A single endoscopist evaluated 2566 consecutive outpatients undergoing elective colonoscopy. Of these, 21 patients were identified with endoscopic evidence of diverticular inflammation.
Findings included erythema and edema of a diverticular opening (n = 8), pus from a diverticular orifice (n = 8), and a polypoid mass of granulation tissue in a diverticular orifice (n = 15).
The research team obtained follow-up in 17 patients a mean of 11.9 months after colonoscopy.
They found that only 1 patient had symptoms of diverticulitis at the time of colonoscopy. This patient improved with antibiotic therapy.
In addition, 6 patients had experienced symptoms of abdominal pain or fever, but only 1 had a diagnosed episode of acute diverticulitis before colonoscopy.
None of the patients had acute diverticulitis during the follow-up interval.
Dr Sujoy Ghorai's team concluded, "Endoscopic findings of diverticular inflammation were identified in about 0.8% of patients undergoing colonoscopy without clinical evidence of diverticulitis".
"Most patients are asymptomatic at the time of colonoscopy, and antibiotic therapy is generally unnecessary".
