Informasjon til deltakere i Scandiv studien

SCANDIV II is and exploratory, prospective, longitudinal, non-interventional, multicentre study for the evaluation of treatment of patients with acute complicated diverticulitis. We have chosen the Hinchey Classification system (table 1) for description. The treatment of complicated diverticulitis is controversial. Whereas Scandinavian surgeons usually adhere to a watch and wait strategy after a conservatively treated episode of complicated diverticulitis, several international guidelines recommend an elective operation for the majority of these patients.

The aim of this study is to explore the current treatment strategies in patients with acute complicated diverticulitis according to the Hinchey classification in Swedish and Norwegian hospitals and to assess failure rates during a one-year period. Secondly to evaluate the course of the disease for patients with complicated diverticulitis managed without resection surgery. We will also study the quality of life for all patients with complicated diverticulitis.

I: Pericolic abscess

II: Distant/pelvic abscess

III: Generalized purulent peritonitis

IV: Faecal peritonitis
