Endoscopic mucosal resection (EMR) has been widely used as a diagnostic and treatment techniques of gastrointestinal small lesions. Postoperative rebleeding is one of the common complication following EMR. Several endoscopic hemostasis methods are currently in use. EndoClot® absorbable polysaccharide hemostat (PAPH) as a new hemostasis material was previously used for surgical hemostasis, but the therapeutic effect and safety in endoscopic application remains unknown. This study has been designed to observe the effect of rebleeding prevention after EMR.

Further study details as provided by Xijing Hospital of Digestive Diseases:

Primary Outcome Measures:
  • Rebleeding rate after EMR procedure [ Time Frame: up to 1 week ] [ Designated as safety issue: No ]
    Rebleeding rate up to 1 week was obtained by clinical manifestations such as melana; decreased hemoglobin > 20g/L; hemodynamic instability or active bleeding from mucosal defect under endoscope.

Secondary Outcome Measures:
  • Mucosal healing after EMR [ Time Frame: up to 1 month ] [ Designated as safety issue: No ]
    Colonoscopy will be repeated 1 month after EMR procedure to observe if application of Endoclot will delay the musosal healing.

  • gastrointestinal tract obstruction [ Time Frame: up to 1 month ] [ Designated as safety issue: No ]
    Gastrointestinal tract obstruction has been previously reported as a possible adverse effect of hemostats, therefore it was observed in the current study.
