Stepwise endoscopic management of diospyrobezoar-induced small bowel obstruction using long-cap-assisted suction and balloon catheter

Small bowel obstruction caused by diospyrobezoars is often difficult to manage endoscopically, and surgical intervention is therefore frequently selected [ 1 ] [ 2 ] [ 3 ]. We present a case of small bowel obstruction due to ileal diospyrobezoars that was successfully treated using a stepwise endoscopic strategy combining long-cap-assisted suction and an endoscopic retrograde cholangiopancreatography (ERCP) balloon catheter ([ Fig. 1 ]). Fig. 1 Short versus long transparent cap. Short transparent cap (left) and long transparent cap (right). The long cap protrudes 12 mm beyond the endoscope tip and has a larger diameter and inner lumen, facilitating suction and retrieval. To prevent further migration of gastric bezoars into the small bowel, the endoscopic removal of the gastric bezoars was attempted first. Multiple large gastric bezoars were identified in the stomach and fragmented using a guidewire fashioned into a snare and a conventional snare ([ Fig. 2 ] a, b , [ Video 1 ]). When grasping was ineffective, the bezoar was pressed against the rim of the long cap to facilitate fragmentation [ 4 ] ([ Video 1 ]). Retrieval with a net was difficult because of physiological esophageal narrowing at the esophageal hiatus and tracheal bifurcation; however, long-cap–assisted suction enabled effective removal, with no clinically significant residual gastric bezoars [ 5 ] ([ Fig. 2 ] c, d , [ Video 1 ]).

Fluoroscopy revealed two bezoars in the ileum ([ Fig. 3 ] a ). Because direct endoscopic access was difficult, the more distal bezoar was mobilized to the ileal flexure using an ERCP balloon catheter ([ Fig. 3 ] b , [ Video 1 ]). Owing to sharp ileal angulation and the large size of the bezoar, advancement into the colon was not feasible; therefore, it was repositioned, fragmented within the ileum, and retrieved using long-capassisted suction ([ Fig. 3 ] c, d , [ Video 1 ]). The second, smaller ileal bezoar was similarly mobilized, grasped with a snare, and retrieved to the level of the ileocecal valve ([ Fig. 3 ] e , [ Video 1 ]). The final fluoroscopic and endoscopic evaluation confirmed that no clinically significant residual ileal bezoars remained, with resolution of the small bowel obstruction ([ Fig. 3 ] f , [ Video 1 ]).

This stepwise endoscopic approach represents a practical and minimally invasive option for managing diospyrobezoar-induced small bowel obstruction and may help avoid surgical intervention.
