Endoscopic injection sclerosis in bleeding gastric varices

Area of Science:

• Gastroenterology
• Hepatology
• Endoscopy

Background:

• Bleeding gastric varices represent a significant challenge in managing portal hypertension.
• Esophageal varices are more commonly studied, with gastric varices often considered a distinct clinical entity.

Purpose of the Study:

• To evaluate the efficacy and safety of endoscopic injection sclerotherapy in controlling bleeding gastric varices.
• To compare outcomes of gastric variceal bleeding treated with sclerotherapy to those of esophageal variceal bleeding.

Main Methods:

• Prospective study of 92 patients with bleeding varices undergoing sclerotherapy.
• Identification and analysis of a subset of 9 patients with gastric variceal bleeding.
• Comparison of blood transfusions, hospital days, costs, and outcomes between gastric and esophageal variceal groups.

Main Results:

• Gastric variceal bleeding occurred in 10% of patients, requiring 34 bleeding sessions.
• Higher rebleeding rates, mortality, and complications were observed in the gastric variceal group.
• Gastric ulcerations at sclerotherapy sites caused rebleeding in 37% of patients, with lower survival rates.

Conclusions:

• Endoscopic injection sclerotherapy offers only temporary control for bleeding gastric varices.
• High incidence of early rebleeding and complications necessitates alternative management or modified sclerotherapy techniques.
