Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A prospective, randomized, controlled study to compare the efficacy and safety of underwater endoscopic mucosal resection and conventional endoscopic mucosal resection in removal of non-pedunculated colorectal polyps

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

* Patients are undergone colonoscopy at the Endoscopy department of Ho Chi Minh City University Medical Center.
* Randomize patients with non-pedunculated polyp of 10mm or larger in size into 2 interventional groups based on Random function of Statistical Package for the Social Sciences (SPSS) 20.0, including (1) Group 1: Underwater endoscopic mucosal resection (UEMR) and (2) Group 2: Conventional endoscopic mucosal resection (CEMR).
* The time of local recurrence assessment depends on the histopathology of polyps. Polyps with low grade dysplasia are followed up at 6 months, while polyps with high grade dysplasia are followed at 3 months.
* Collecting variables which consist of primary and secodary outcomes.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Underwater endoscopic mucosal resection

Intervention: Non-pedunculated polyps will be removed by underwater endoscopic mucosal resection. The UEMR procedure included the following: (1) complete deflation of the colorectal lumen; (2) total immersion of the lesion in normal saline using a mechanical water pump; (3) snaring the lesion and the surrounding mucosa; and (4) resection using electrocautery.

Group Type EXPERIMENTAL

Endoscopic resection

Intervention Type PROCEDURE

Group 1: Polyps are resected by UEMR Group 2: Polyps are resected by CEMR

Conventional endoscopic mucosal resection

Intervention: Non-pedunculated polyps will be removed by conventional endoscopic mucosal resection. The CEMR procedure included the following: (1) needle injection of normal saline into the submucosa; (2) entrapment of the mucosal protrusion with a snare; and (3) resection applying the same electrocautery setting as was used for UEMR.
