    A novel bipolar electrocoagulator effectively stops upper gastrointestinal bleeding in most patients. This endoscopic tool provides immediate hemostasis, proving safe and a promising alternative to surgery for bleeding management.

    Area of Science:

    • Gastroenterology
    • Endoscopic Surgery

    Background:

    • Upper gastrointestinal bleeding is a significant clinical challenge.
    • Current endoscopic hemostatic methods have limitations.

    Purpose of the Study:

    • To evaluate the efficacy and safety of a new endoscopically deliverable bipolar electrocoagulator.
    • To assess its potential as an alternative to surgical intervention for gastrointestinal hemorrhage.

    Main Methods:

    • A new bipolar electrocoagulator device was developed for endoscopic use.
    • The device was clinically applied to 53 patients with upper gastrointestinal bleeding on 61 occasions.
    • Direct electrode application to bleeding vessels was performed for hemostasis.

    Main Results:

    Related Experiment Videos

  • Immediate hemostasis was achieved in 52 of 53 bleeding vessels (98%).
  • Permanent hemostasis was achieved in 44 patients (83%), averting emergency surgery in most.
  • Rebleeding occurred in 8 patients (15%), primarily those with acute mucosal lesions and serious comorbidities. No procedure-related complications were observed.

    • Conclusions:

    • The developed bipolar electrocoagulator is a safe and easily applicable endoscopic hemostatic technique.
    • It shows promise as an effective addition to existing methods for managing upper gastrointestinal bleeding.
    • The device successfully achieved hemostasis and reduced the need for emergency operations.
