An interventional study of colon capsule endoscopy in Diverticulitis, Colonic, sponsored by Odense University Hospital. Status unknown at 1 site in Denmark. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2023-09-11.
Sponsored by Odense University Hospital · Not applicable, Interventional, and Diagnostic
Introduction: Follow-up after colonic diverticulitis is a common indication for colonoscopy, even though studies have shown a low risk of positive findings in this population. The objective is to investigate colon capsule endoscopy (CCE) as a follow-up examination in patients with colonic diverticulitis compared to colonoscopy, on patient satisfaction and clinical performance.
Methods and Analysis: The investigators will conduct a single centre prospective randomized controlled trial. Patients seen at Odense University Hospital with acute diverticulitis confirmed by CT will be included and randomized to either follow-up by colonoscopy or CCE. Detection of suspected cancer, more than two polyps or any number of polyps larger than 9mm in CCE will generate an invitation to a diagnostic colonoscopy for biopsies or polyp removal. The investigators will compare colonoscopy and CCE regarding patient satisfaction and tolerance, the number of complete examinations, the number of patients referred to a subsequent colonoscopy after CCE and the prevalence of diverticula, polyps, cancers and other abnormal findings.
Colon diverticulosis (CD) is extremely common and the prevalence seems to increase globally. The prevalence of CD increases with age and two-thirds of the adult population eventually develop CD. In the US the prevalence of CD was 32.6 % in patients aged 50-59 years and 71.4% in patients > 80 years of age. CD is often detected incidentally during optical colonoscopy (OC) or by computer tomography (CT). In approximately 25 % of patients with CD symptomatic colon diverticular disease develop typically comprising bloating, abdominal pain and change in bowel habits. Progression to diverticulitis is estimated to appear in approximately 1%. Most patients present with uncomplicated diverticulitis and are managed by general practitioners (GP) with the use of painkillers and oral antibiotics. Complicated diverticulitis due to perforation can be classified according to Hinchey et al. as a guidance to surgeon as to how conservative they can be. Hinchey level 1-2 can be managed conservatively. In the case of Hinchey level 3 and 4 it requires a laparoscopy with peritoneal lavage or laparotomy with colon resection and stoma formation, respectively. In patients presenting at the GP with intractable pain or signs of sepsis admission to hospital services is mandatory. Upon hospitalization, CT is the preferred diagnostic imaging modality in patients presenting with abdominal pain and suspected diverticulitis. If colonic diverticulitis is described as the symptoms-eliciting pathology without complications comprising abscess or bowel perforation patients are typically discharged from hospital with painkillers and offered an OC within 4-6 weeks, when the inflammation has resolved, to confirm the diverticulitis diagnosis. Routine OC after an episode of diverticulitis is recommended by the majority of international guidelines including Danish guidelines on handling of patients with diverticulitis. Due to a very low risk of malignancy in patients with diverticulitis the relevance of routine OC has been questioned in a recent review. The research in Colon Capsule Endoscopy (CCE) has evolved substantially since the introduction in 2006. More studies have reported a diagnostic yield equal to OC also in regard to larger polyps > 9 mm. In contrast to OC, CCE does not offer the possibility of biopsy or removal polyp. Hence, the ideal population for CCE needs to have low risk of findings with the need of endoscopic intervention. CCE is without pain and the risk of complications is extremely low compared to colonoscopy for which the estimated risk of major bleeding or perforation is 12 per 10,000 patients.
The investigators aimed to evaluate the effect of introducing CCE on patient satisfaction and discomfort compared to colonoscopy as a follow-up examination in patients with diverticulitis and the impact of introducing CCE on the need for subsequent colonoscopy.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Patients randomized to colon capsule endoscopy
Diagnostic Test: colon capsule endoscopy
Patients randomized to colonoscopy
Patient allocated for the intervention arm will have a CCE using the PillCam Colon 2 (Medtronic, Minneapolis, Minnesota, USA). Upon inclusion and allocation to the intervention arm patients are contacted by a dedicated CCE nurse. The course of the CCE procedure and preparations are explained thoroughly. In case of additional questions patients can contact the nurses by telephone during office hours (Monday-Friday, 8am-3pm). Before the CCE participants will have to undergo a bowel preparation procedure. The bowel preparation kit will be distributed by mail and is to be completed at home, beginning 72 hours before the CCE. The kit contains polyethylene glycol (PEG) sachets (Movicol, Norgine Danmark A/S, Herlev, Denmark), PEG solutions (MoviPrep, Norgine Danmark A/S, Herlev Denmark) and instructions on how to properly perform the preparation procedures.
