Controlled trial of liquid monopolar electrocoagulation in bleeding peptic ulcers.

Abstract

The aim of this study was to evaluate the efficacy and the safety of liquid monopolar electrocoagulation in the endoscopic control of major haemorrhage from peptic ulcers. During the 24-month period of the trial, emergency endoscopy was performed on 480 patients consecutively admitted with acute upper gastrointestinal tract hemorrhage. Ulcers were seen in 168 cases (35%). Seventy-eight of these were included in the trial. Active bleeding was present in 21 cases and stigmata of recent bleeding were observed in 57. Immediate hemostasis was achieved in nine of 11 patients with active bleeding ulcers. However, active bleeding can stop spontaneously (as in four of 10 control patients), which reemphasizes the importance of randomized studies. There was a trend toward hemostatic benefit for the electrocoagulation-treated patients with actively bleeding ulcers. In the group of 31 patients with visible vessels, the electrocoagulation treatment reduced significantly both the rate of rebleeding and the emergency surgery. In the group of 26 patients with other stigmata of recent bleeding (fresh or altered clot, or black spots), only in two cases allocated to placebo treatment occurred rebleeding. These patients are at minimal risk of further bleeding. The results offer support to the contention that liquid monopolar electrocoagulation is a safe and effective method of reducing the incidence of further bleeding and emergency surgery. This new technique has the advantages of low cost, easy maintenance, durability, and portability.
