[Sigmoid diverticulitis. Emergency intervention in abscess, hemorrhage and stenosis].

Interventional techniques in treatment of complicated diverticulitis gain more and more importance. In particular abscesses and bleeding are treated successfully. In case of diverticular abscess (Hinchey classification stage I and II) percutaneous drainages are placed sonographically or CT guided. Interventional drainage offers the possibility of elective one-stage surgical treatment of diverticulitis with significant reduce of mortality and morbidity rates. Diverticular bleeding is usually diagnosed and treated endoscopically. Only if endoscopy is not able to manage bleeding, angiography or nuclear scan is demanded. In case of stenosis endoscopic treatment has not jet gained clinical relevance.
