Abstract

Objective: To evaluate the treatment outcomes of sessile colorectal polyps larger than 20mm using piecemeal endoscopic mucosal resection. Subjects and methods: A descriptive study of a cluster of cases involving 32 patients with colorectal polyps larger than 20mm, treated using the PEMR method at the Gastroenterology and Hepatology Center of bach Mai Hospital from June 2023 to June 2024. Results: Polyps in the sigmoid area accounted for the highest rate of 34,4%. The average size of polyps was 25,78mm (the smallest was 20 mm, the largest was 100 mm). The average time to successfully complete the procedure was 24,72 minutes. Among the 32 cases, there were 3 cases of intra-procedural bleeding, but all cases episodes were managed endoscopically without the need for surgery, and 1 case of bleeding within 24 hours after PEMR. There were no cases of perforation. The majority of patients had a hospital stay of 1 day (46,9%) and 2 days for 21,9%. Follow-up examinations after treatment revealed 3 cases of recurrence (11,1%). All 3 cases were neoplastic polyps, with 2 cases being precancerous lesions (66,7%) and 1 case being carcinoma (33,3%). Conclusion: The PEMR technique for colorectal polyp removal is safe and effective, but caution is needed when applied to neoplastic polyps.
