An intestinal occlusion device for prevention of small bowel distention during transgastric natural orifice transluminal endoscopic surgery

Research output: Contribution to journalArticle

Abstract

Background and Objectives: Bowel distention from luminal gas insufflation reduces the peritoneal operative domain during natural orifice transluminal endoscopic surgery (NOTES) procedures, increases the risk for iatrogenic injury, and leads to postoperative patient discomfort. Methods: A prototype duodenal occlusion device was placed in the duodenum before NOTES in 28 female pigs. The occlusion balloon was inflated and left in place during the procedure, and small bowel distension was subjectively graded. One animal had no balloon occlusion, and 4 animals had a noncompliant balloon placed. Results: The balloon maintained its position and duodenal occlusion in 22 animals (79%) in which the bowel distention was rated as none (15), minor (4), moderate (3), or severe (0). The intestinal occlusion catheter failed in 6 animals (21%) because of balloon leak (5) or back-migration into the stomach (1), with distention rated as severe in 5 of these 6 cases. Conclusion: The intestinal occlusion catheter that maintains duodenal occlusion significantly improves the intraabdominal working domain with enhanced visualization of the viscera during the NOTES procedure while requiring minimal time and expense.
