Objective To observe the application effect of double balloon enteroscopy (DBE) in polypectomy.

Methods Clinical materials of 34 patients with DBE assisted polypectomy for small intestinal polyps were retrospectively analyzed, and the experience in using various accessories during DBE assisted polypectomy as well as various preventive measures for complications such as perforation, bleeding, abdominal distension and pain were summarized.

Results Among the 34 patients, except for one patient who was converted to surgical operation due to excessive polyps blocking the intestinal lumen, the other 33 patients successfully completed the DBE assisted polypectomy for small intestinal polyps; one patient suffered from delayed hemorrhage and successfully stopped bleedingunder endoscopy, with a complication rate of 3.0%. All the patients were discharged smoothly after careful nursing, with an average hospital stay of (2.21±0.47) days.

Conclusion The polypectomy under DBE is safe and reliable in the resection of intestinal polyps. Sufficient preoperative preparation, good intraoperative cooperation between doctors and nurses, skilled operation, and strict postoperative observation are important guarantees for the success of intestinal polyp resection under DBE, which can reduce the incidence rate of complications and promote the recovery of patients.
