Abstract
Re-bleeding following endoscopic therapy for gastrointestinal bleeding remains common probably because injection and thermal methods for treating bleeding are of limited efficacy, especially in the presence of a large bleeding artery. This chapter reviews mechanical methods of endoscopic haemostasis. The design of clips, which can be delivered through flexible endoscopes, is reviewed with experimental and clinical data of their efficacy. The need for improvements in clip design is stressed. Experimental studies and preliminary clinical data where available on a variety of other mechanical methods of haemostasis are presented, including band ligation, endoloops, sewing machines, stapling machines, ulcer clamps, corkscrews, balloon tamponade and ferromagnetic tamponade. New, less invasive, surgical methods which might have a place in ulcer haemostasis, including transgastric endoluminal surgery and flexible endoscopic ulcer excision with wound closure, are discussed. Mechanical methods offer the best prospect for improvements in security of endoscopic haemostasis for bleeding peptic ulcer. More development is required if the results are to improve.
