Study 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.

Methods:

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.

What researchers measure

Primary outcomes

  1. correlation between prior abdominal surgery and the development of diverticulosis

    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

    Time frame: in the end of the study (estimated in 1 year)

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 26, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
