Gastric outlet obstruction.
Acquired gastric outlet obstruction is more commonly owing to malignancy than ulcer disease. Endoscopy is the preferred method for diagnosis. Surgical palliation for malignant disease has poor results and high rates of morbidity and mortality. Initial experiences with endoscopic palliation with expandable metallic endoprostheses appear promising. Peptic ulcer-induced gastric outlet obstruction can be treated safely with endoscopic balloon dilation. About 65% of patients have sustained symptom relief, but many require more than one dilation session. Outcomes may be improved with effective ulcer therapy with acid reduction and eradication of H. pylori. Surgery is associated with significant morbidity and mortality and should be reserved for endoscopic treatment failures.
