Following acute diverticulitis, colonoscopy is advised to rule out malignancy.
Commonly, the colonoscopy is postponed to avoid the potential risk of perforation.
In a previous pilot, noncontrolled study, it was shown that early colonoscopy is feasible in patients with acute diverticulitis.
Dr Lahat and colleagues from Israel conducted a randomized controlled trial to compare early and late colonoscopy in hospitalized patients with acute diverticulitis.
|Early colonoscopy in acute diverticulitis has greater compliance|
The team evaluated 154 patients with acute diverticulitis were hospitalized between 2004 and 2006.
Of these, 35 patients were excluded because of either free perforation or pericolic air on computed tomography (CT).
The team excluded another 18 patients because they had undergone colonoscopy in the previous year.
The research team offered the remaining 101 patients the possibility of participating in the study.
Randomization was refused by 15 patients, and 86 were included in the study.
The researchers randomly allocated 45 patients to early in-hospital colonoscopy or 41 to late colonoscopy, 6 weeks later.
There were 3 patients that did not present for the examination in the early group.
The team reported that 10 patients did not present for the examination, in the late group.
The team noted that the cecum could not be reached in 8 and 3 patients from the early and late groups, respectively.
The colonoscopy revealed polyps in 5 patients, of which 2 were in the early group and 3 in the late group.
No malignancy was detected.
The researchers observed no complications in either group.Dr Lahat's team concluded, "Early colonoscopy in acute diverticulitis is feasible and safe in the absence of pericolic air on CT, and has greater compliance."
"However, no added value is apparent compared with the CT scan currently used."
