The goal of this observational study is to study the emergency surgical treatment of diverticular disease in Sweden outside clinical trials. The main questions it aims to answer are: * Which is the preferred surgical method of acute diverticular disease in Sweden? * Which are the short and long-term outcomes of the different surgical methods? Researchers will compare the different methods to see if there is a surgical operation that is superior for the treatment of acute diverticulitis.
A retrospective study of patients who were admitted to a Swedish hospital between 1st July 2014 and 31st December 2020 with an ICD-10 code for diverticular disease of the large intestine (K57.2- K57.9) will be included. Patients who underwent procedures relevant to diverticulitis will be identified and therefore will be included. Procedures will be grouped into two categories: Laparoscopic peritoneal lavage (Group I), and sigmoid resection with or without stoma (Group II). The cohort will be studied from 1st January 1997 until the index date aiming to assess comorbidities, previous abdominal surgeries, and admissions for diverticular disease. A Charlson Comorbidity Index (CCI) system adjusted for Swedish ICD-10 version will be used to calculate a composite score to reflect comorbidity.
