Abstract
The ACM 2.3 mm Bicap probe was found to be very safe in canine stomach and stopped bleeding from experimental canine ulcers. It was less successful in arresting haemorrhage from mesenteric arteries when the external diameter exceeded 1 mm. Twenty-five patients who presented with upper gastro-intestinal bleeding have been treated with this device, and it was possible to stop active bleeding in 5 of 7 cases. Of the remaining patients, 17 had peptic ulcers with a visible vessel, only 4 of these rebled following electrocoagulation (only 1 massively). The ACM Bicap probe is a safe and effective instrument for stopping bleeding from arteries of 1 mm in diameter or less, but is unlikely to be useful if a larger vessel is responsible for the haemorrhage.
