The individual surgeon's training, experience and flexibility are decisive factors in the successful recovery of patients after surgery for acute bleeding peptic ulcer. With planned management, careful preparation for surgery should be considered as of equal importance to surgical skill. Early diagnosis and exact resuscitation are the two most important aspects of a plan of treatment which anticipates the need for early surgery. In the past, patients were often referred late for surgery after significant blood loss and transfusion. Surgeons have endeavoured to define the cases that are likely to rebleed and prepare them promptly for surgery. Probably the best indications for early surgery are severe haemorrhage, reflected by shock on admission, an age of over 50 and active bleeding from the ulcer seen at diagnostic endoscopy. Prospective studies have shown a reduction in mortality from bleeding ulcer where policy requires early endoscopic diagnosis, exact resuscitation in the intensive care unit and early surgery in high risk cases.
