Colonoscopy-Induced Acute Diverticulitis

ABSTRACT

Even though colonoscopy is a common and widely performed procedure, it can cause many complications. If any sign of inflammation is observed, a perforation or postpolypectomy coagulation syndrome should be considered. Diverticulitis, a very rare complication with an incidence of 0.04% to 0.08%, also can occur after the diagnostic and therapeutic procedure. We report a case of acute diverticulitis after colonoscopy, diagnosed with typical computed tomography findings after excluding other complications. The patient was treated in the same manner as for complicated diverticulitis, with bowel rest, hydration, and broad-spectrum antibiotics. Acute diverticulitis as a rare complication can occur following prolonged colonoscopy or colonoscopic polypectomy, especially in those with additional risk factors such as obesity and smoking.
