Brief Summary:

Background & Aims:

Abnormal colonic pressure profiles have been associated with an increased risk of colonic diverticulosis. A surgical history is a known risk factor for abdominal adhesions, and these may lead to increased intraluminal colonic pressure. We assessed whether previous abdominal surgery is associated with colonic diverticulosis or diverticulitis.


The investigators analyzed data from a prospective study of patients undergoing colonoscopy for different indications from 2020 through 2021. Patients completed a structured questionnaire concerning previous abdominal surgeries, dietary and lifestyle exposures including smoking and alcohol use, and co-morbidities.

    abdominal surgery as a risk factor for diverticulosis

Primary Outcome Measures :
  1. correlation between prior abdominal surgery and the development of diverticulosis [ Time Frame: in the end of the study (estimated in 1 year) ]
    the investigators are willing to see if prior abdominal surgery raise the patient's risk of developing future diverticulosis. The investigators use questionere to collect data from patients. The final measurements will be calculatrd with spss software
