ABSTRACT
BACKGROUND AND AIM: We aimed to prospectively determine patient burden and patient preference for magnetic resonance enteroclysis, capsule endoscopy and balloon-assisted enteroscopy in patients with suspected or known Crohn's disease (CD) or occult gastrointestinal bleeding (OGIB). METHODS: Consecutive consenting patients with CD or OGIB underwent magnetic resonance enteroclysis, capsule endoscopy and balloon-assisted enteroscopy. Capsule endoscopy was only performed if magnetic resonance enteroclysis showed no high-grade small bowel stenosis. Patient preference and burden was evaluated by means of standardized questionnaires at five moments in time. RESULTS: From January 2007 until March 2009, 76 patients were included (M/F 31/45; mean age 46.9 years; range 20.0-78.4 years): 38 patients with OGIB and 38 with suspected or known CD. Seventeen patients did not undergo capsule endoscopy because of high-grade stenosis. Ninety-five percent (344/363) of the questionnaires were suitable for evaluation. Capsule endoscopy was significantly favored over magnetic resonance enteroclysis and balloon-assisted enteroscopy with respect to bowel preparation, swallowing of the capsule (compared to insertion of the tube/scope), burden of the entire examination, duration and accordance with the pre-study information. Capsule endoscopy and magnetic resonance enteroclysis were significantly preferred over balloon-assisted enteroscopy for clarity of explanation of the examination, and magnetic resonance enteroclysis was significantly preferred over balloon-assisted enteroscopy for bowel preparation, painfulness and burden of the entire examination. Balloon-assisted enteroscopy was significantly favored over magnetic resonance enteroclysis for insertion of the scope and procedure duration. Pre- and post-study the order of preference was capsule endoscopy, magnetic resonance enteroclysis and balloon-assisted enteroscopy. CONCLUSION: Capsule endoscopy was preferred to magnetic resonance enteroclysis and balloon-assisted enteroscopy; it also had the lowest burden. Magnetic resonance enteroclysis was preferred over balloon-assisted enteroscopy for clarity of explanation of the examination, bowel preparation, painfulness and burden of the entire examination, and balloon-assisted enteroscopy over magnetic resonance enteroclysis for scope insertion and study duration.

BACKGROUND: Gastrojejunal strictures following laparoscopic Roux-en-Y gastric bypass (LRYGBP) present with dysphagia, nausea, and vomiting. Diagnosis is made by endoscopy and/or radiographic studies. Therapeutic options include endoscopic dilation and surgical revision. METHODS: Of 369 LRYGBP performed, 19 patients developed anastomotic stricture (5.1%). One additional patient was referred from another facility. Pneumatic balloons were used for initial dilation in all patients. Savary-Gilliard bougies were used for some of the subsequent dilations. RESULTS: Flexible endoscopy was diagnostic in all 20 patients allowing dilation in 18 (90%). Two patients did not undergo endoscopic dilation because of anastomotic obstruction and ulcer. The median time to stricture development was 32 days (range: 17-85). Most patients (78%) required more than two dilations. The complication rate was 1.6% (one case of microperforation). At a mean follow-up of 21 months, all patients were symptom-free. CONCLUSIONS: Gastrojejunostomy stricture following LRYGBP is associated with substantial morbidity and patient dissatisfaction. Based on our experience, we propose a clinical grading system and present our strategy for managing gastrojejunal strictures.
