Endoscopic thermal ablation effectively treats upper-GI vascular ectasias, reducing bleeding and transfusion needs. Gastric antral vascular ectasia requires more sessions than angiodysplasia for successful outcomes.

Area of Science:

  • Gastroenterology
  • Endoscopy
  • Vascular Medicine

Background:

  • Upper-GI vascular ectasias, such as angiodysplasia and gastric antral vascular ectasia (GAVE), are common causes of gastrointestinal bleeding.
  • Endoscopic thermal therapies are established treatments for acute bleeding and reducing transfusion dependency.

Purpose of the Study:

  • To evaluate the efficacy of endoscopic thermal ablation in managing upper-GI vascular ectasias.
  • To compare treatment outcomes and session requirements for angiodysplasia and GAVE.

Main Methods:

  • A 6-year retrospective review of 32 patients with upper-GI vascular ectasias requiring transfusions.
  • Patients were treated with Nd:YAG laser, multipolar electrocoagulation, or argon plasma coagulation (APC).
  • Treatment response assessed by changes in hemoglobin and transfusion requirements.

Main Results:

  • Endoscopic therapy improved mean hemoglobin levels in both GAVE and angiodysplasia patients.
  • Transfusion requirements were reduced or eliminated in 93% of GAVE and 76% of angiodysplasia patients.
  • GAVE patients required a mean of 6 sessions, while angiodysplasia patients needed 1-2 sessions.

Conclusions:

  • Endoscopic thermal ablation is effective for controlling bleeding and reducing transfusions in upper-GI vascular ectasias.
  • Gastric antral vascular ectasia necessitates significantly more treatment sessions compared to angiodysplasia.
