Intrinsic or extrinsic obstruction of the pyloric channel or duodenum either by benign or malignant diseases leads to gastric outlet obstruction. With improvement in science and technology, the spectrum of gastric outlet obstruction has changed from peptic ulcer disease to corrosives and malignant diseases. Newer investigations like computerized tomography and endoscopy have supplemented the previous clinical tests like saline load test and barium series. Improvised treatment modalities like endoscopic balloon dilatation and endoscopic incision have circumvented the use of surgery which was the gold standard for management of gastric outlet obstruction. Newer modalities like biodegradable stents have an upcoming role in the management.
幽门管或十二指肠的内在性或外在性梗阻，无论是由良性还是恶性疾病引起，均可导致胃出口梗阻。随着科学技术的进步，胃出口梗阻的范围已从消化性溃疡疾病转变为腐蚀性疾病和恶性疾病。计算机断层扫描和内镜检查等新的检查方法补充了以往的盐水负荷试验和钡餐造影等临床检查。内镜球囊扩张和内镜切开等改进的治疗方式避免了使用曾作为胃出口梗阻治疗金标准的手术。可生物降解支架等新的治疗方式在治疗中即将发挥作用。
