Brief summary

A prospective, single-center, open-label, randomized controlled study to compare the effectiveness and safety of underwater endoscopic mucosal resection (UEMR) and hot snare polypectomy (HSP) in treating Pedunculated colorectal polyps less than 10mm in size.

Detailed description

1. Patients are undergone screening, surveillance, or therapeutic colonoscopy at the Endoscopy department of Gastrointestinal endoscopy center of Huadong hospital affiliated to Fudan University. 2. Randomize patients with pedunculated colorectal polyps less than 10mm 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: Hot snare polypectomy (HSP). 3. Collecting variables which consist of primary and secodary outcomes.

Design outcomes

Primary

MeasureTime frameDescription
Post-polypectomy Bleeding2 weeks after the procedurePresence of Clinically Significant Immediate Post-polypectomy Bleeding(CSIPB) or Clinically Significant Delayed Post-polypectomy Bleeding (CSDPB). CSIPB was defined as any bleeding not responding to water jet irrigation or STSC and therefore requiring either coagu lation forceps or mechanical clips to achieve hemostasis. CSDPB was defined as any bleeding after completion of the procedure requiring emergency room presentation, hospital isation or re-intervention (endoscopy, angiography, surgery).

Secondary

MeasureTime frameDescription
postoperative electrocoagulation syndrome2 weeks after the procedurePostoperative electrocoagulation syndrome (PEECS)defined as localized abdominal tenderness plus at least one of the following: (1) body temperature \> 37.6 °C; (2) white-blood-cell count \> 10 × 10⁹ /L; or (3) C-reactive protein \> 0.5 mg/dL, after ruling out delayed postoperative perforation).
