Background:
Inflammatory bowel diseases (IBD) are listed as a contraindication for bariatric surgery in various guidelines due to a theoretical higher complication risk. Therefore, little is known about safety and efficacy of bariatric surgery in IBD patients.
Aim:
We assessed the safety and efficacy of bariatric surgery and postoperative quality of life (QoL) in IBD patients.
Setting:
The study was conducted in a large peripheral hospital in the Netherlands.
Methods:
All IBD patients who underwent bariatric surgery in our facility were included. Complications, mortality, reoperations, and micronutrient deficiencies were analyzed. Weight loss was assessed 6, 12, and 24 months after surgery. Postoperative QoL was assessed using a disease-specific Inflammatory Bowel Disease Questionnaire (IBDQ).
Results:
Forty-five patients were included in this study, all diagnosed with IBD (16 ulcerative colitis (UC) and 29 Crohn's disease (CD)) prior to bariatric surgery. Bariatric procedures included Roux-en-Y gastric bypass, sleeve gastrectomy, gastric banding, and revisional surgery. There was no mortality in the entire follow-up period and there were no major perioperative complications. Two major complications in two CD patients occurred during follow-up, gastro-enterostomy bleeding and pyelonephritis with secondary pancreatitis. Mean percentage (± SD) of overall excess weight loss (%EWL) and total body weight loss (%TBWL), 12 months after surgery, were 62.9 ± 27.1 and 26.2 ± 10.6%, respectively. Twenty-four months postoperatively, mean overall %EWL and %TBWL were similar for both UC and CD patients and were 62.9 ± 31.0 and 26.6 ± 12.2, respectively. Mean Bariatric Analysis and Reporting Outcome System (BAROS) score was 3.34 ± 2.42. Median total IBDQ score was 170.8 (min. 77; max. 218). Both scores did not differ significantly between UC and CD patients.
Conclusion:
As bariatric procedures appear safe and effective in this CU and CD population, one could question why bariatric surgery is contraindicated in the patients. Nevertheless, close lifelong monitoring to assure safety and a favorable outcome remains essential.

01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
