Patients presenting in hospital with symptoms of acute diverticulitis. Acute inflammation of the left-sided colon is confirmed with CT scan or ultrasound in experienced centers and diagnosis is defined according to the "Classification of Diverticular Disease (CDD)". CDD Type 2a, 2b and 3b will be included and then randomized in two groups. Group A will get an early left hemicolectomy 7 to 10 days after admission and initial antibiotic therapy and/or drainage of the abscess. Group B is designated for an elective resection 6 to 8 weeks after dismissal at the earliest and initial conservative treatment and/or after drainage of the abscess. Six weeks after the operation patients of Group A will be asked for their present quality of life with a standardized scoring system (Gastrointestinal Quality of Life Index = GIQLI; Short-form 36 Score = SF-36 Score; Low anterior resection syndrome = LARS Score). Group B (elective resection) will be asked at their readmission prior to elective surgery is done. This survey package will be repeated again 6 to 8 weeks later in both groups. Primary endpoints will be the two GIQLI at the said examination times. Secondary endpoints will be SF-36 score, LARS-score, GIQLI-Domains, anastomosis insufficiency and other complications, mortality and length of hospital stay. Comparisons between the groups are made at the said examination times but also 6-8 weeks after the operation.

Patients with diverticulitis experience a prolonged course of the disease and report a variety of physical, psychological and social symptoms, which highly impacts in their quality of life. Although antibiotic therapy has been the preferred treatment option for acute diverticulitis, it does not control the disease in 40 percent of the patients with complicated diverticulitis and 13 to 23 percent of the patients with non-complicated diverticulitis, which results in chronic and recurrent episodes of diverticulitis. As the episodes repeat, the outpatient conservative treatment has worse success rates and the incidence of complicated diverticulitis with abscess increases up to five times. Therefore, it is of great importance to establish new treatments in order to avoid the recurrences of the disease. As of today, there is not enough evidence of the efficacy of current treatment options to prevent recurrences in patients with diverticulitis, but recent approaches suggest the modification of intestinal microbiota as a preventive strategy. Microbial imbalance (dysbiosis) has been proposed as a mechanism involved in the transition from diverticulosis to diverticulitis, inflammation and some of the symptoms of the disease. In this way, fecal microbiota transplantation (FMT) could have an important role in the prevention of new episodes, as it can modify the composition of the intestinal microbiota in a less invasive and more physiological way. Until now the efficacy of FMT in patients with recurrent diverticulitis has not been assessed; however, its benefits and safety have been demonstrated in studies for inflammatory bowel disease (IBD), a pathology with similarities to diverticulitis in its symptoms and underlying inflammation. The objective of the present clinical trial is to assess the efficacy of MBK-01 (heterologous lyophilized intestinal microbiota oral capsules) in reducing the frequency of episodes in recurrent diverticulitis, its safety and tolerability and to determine the optimal dosing regimen.
NCT03994978
The decision to perform a surgical intervention or not after recovery from repeated uncomplicated episodes of acute diverticulitis remains controversial and the literature shows different conflicting approaches based on low-quality evidence.The goal of this trial is to achieve a better understanding of the impact of surgery on bowel function and QoL in patients with recurrent uncomplicated sigmoid diverticulitis in order to develop treatment guidelines.
NCT04311385
The severity of diverticulitis is usually graded with the use of modified Hinchey Criteria. However, there is a condition often seen in the CT scan that is not included in this classification itself; 1-2 pericolic bubbles but no free air or fluid into the abdomen or above the liver. Outcome in these patients remains unknown. We aim to analyse the treatment that these patients and their evolution over the first year after the diagnosis in order to predict the disease related outcome. The study is set up as a retrospective multicentre observational study. Inclusion criteria are Patients over 18 years old, Diagnosed of acute diverticulitis with a CT scan reported as 1-2 pericolic bubbles with or without free fluid. Exclusion criteria: 1) CT scan showing free distant bubbles in the abdomen. 2) CT scan showing abscess. Accepting an alpha risk of 0.05 and a beta risk of 0.2 in a two-sided test, 137 subjects are necessary in the observed group to recognize a difference in morbidity greater than or equal to 10%. A proportion in the reference group has been estimated to be 20%. It has been anticipated a drop-out rate of 0%. Primary outcome is 30-day morbidity and mortality. Secondary outcomes include malignancy and 1 year morbidity including recurrences and ongoing disease. Data will be collected in an online repository. The CT scans will be reviewed by 2 experienced independent radiologists. The management of these patients at the moment of the diagnosis will be recorded, as well as their evolution over the first year during the outpatient clinics. Figure 1 represents the study flow chart. Data will be collected in an online secure and protected repository (Castor edc). The planned study period is 2 years (01/06/2020 - 31/12/2021). CT scans will be reviewed by 2 experienced radiologists. Every other CT scan performed during the follow-up will be reviewed by the same radiologists. The management of these patients at the moment of the diagnosis will be recorded, as well as their evolution over the first year during the outpatient clinics. This study protocol is a new approach to an unknown entity in diverticulitis. We are convince that the outcomes are clinically relevant to patients and interesting for all physicians treating diverticulitis.
