Extended Mesenteric Excision in Ileocolic Resections for Crohn's Disease.

Study Purpose

The study is looking at the role of the mesentery in disease recurrence for ileocolic Crohn's disease. It is a prospective study that has been designed to perform extended mesenteric excision on patients undergoing their first ileocolic resection for Crohn's disease. Endoscopic recurrence will be monitored with the hypothesis that patients receiving extended mesenteric ileocolic resection will have reduced endoscopic recurrence at 6 months after resection.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years and Over

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

The current standard of care for ileocolic Crohn's disease (CD) is a limited mesenteric resection. There is growing, but still limited, evidence that extended mesenteric excision during ileocolic resection is beneficial in decreasing disease recurrence. We propose a prospective multicenter cohort study to better understand the role of extended mesenteric excision in ileocolic CD and how it affects disease recurrence. The primary outcome of this study will be the rate of endoscopic recurrence at 6 months in patients undergoing first-time resection for ileocolic CD. Secondary outcomes will include endoscopic recurrence at 18 months and rates of recurrence requiring surgery by 2 years. These outcomes will be compared to historical controls (limited mesenteric resection). Our hypothesis is that patients receiving extended mesenteric ileocolic resection will have reduced endoscopic recurrence at 6 months after resection. As seen in previous studies, advanced mesenteric and mucosal disease predicts increased surgical recurrence.

Arms & Interventions


Experimental: Intervention Arm

Prospective study arm involving an extended mesenteric ileocolic excision.

No Intervention: Control Arm

Historical controls from a retrospective chart review of patients who had a limited ileocolic resection.


Procedure: - Extended mesenteric resection.

Patients will undergo an ileocolic resection involving high ligation of the ileocolic pedicle, complete mobilization of the mesentery off of the retroperitoneum, and resection of the entire mesentery related to the specimen.
