Iterative evaluation of novel access techniques for small bowel obstruction: combining image guided, percutaneous, and endoscopic methods.

To avoid the need for extensive adhesiolysis in patients with small bowel obstruction (SBO). We evaluated the feasibility of using advanced imaging, percutaneous access, and endoscopy as alternative therapies for SBO. Retrospective case series (IDEAL [Idea, Development, Exploration, Assessment, and Long-term Study Collaborative] stages 1 and 2a). Single tertiary referral center. Twelve adults with chronic SBO resulting from inflammatory bowel disease, disseminated cancer, radiation, and/or adhesive disease. Participants were included if they underwent one of three novel access procedures. There were no exclusion criteria. The median age of participants was 67.5 years (range 42-81); two-thirds were women; and median American Society of Anesthesiology class was 3. All participants underwent one of three novel access methods, followed by wire-guided balloon dilation of a narrowed area of small bowel. These methods combined endoscopic, fluoroscopic, and surgical techniques. The techniques were (1) a purely endoscopic approach aided by an over-the-scope double-balloon device, (2) a combined endoscopic and percutaneous approach, and (3) a cut-down approach. Procedural success (defined as successful access to the small bowel and successful balloon dilation of the stenotic area). Secondary outcomes included major complications, recurrence, length of stay, and procedure time. Procedural success was achieved in 10 of 12 patients (83%). At the time of median follow-up of 10 months, recurrence of SBO was observed in two patients. In only one patient, the novel method did not change the treatment plan. No major complications occurred. Conventional operative intervention was avoided in all patients who achieved technical success with one of the novel approaches. The median postprocedure length of hospital stay was 4 days. Median procedure time was 135 min. Novel minimally invasive approaches to SBO represent feasible alternatives to surgical procedures in select patients. Further study should compare these approaches to standard ones as new methods are refined.
