迷走神经切断术后腹泻现已少见,因消化性溃疡多采用高选择性迷走神经切断术取代迷走神经干切断加引流。因无标准定义,迷走神经切断术后腹泻发病率的估计差别较大。当腹泻产生并发症(Visick Ⅲ-Ⅳ)或水泻(每天三次以上)伴有急迫或大便失禁而影响病人正常生活和社交活动时,方可诊断为严重腹泻。据报道严重腹泻的发病率为0.5～8%,平均4%。病因:迷走神经切断术后腹泻常合并倾倒综合征,并合并液体饮食快速排空,因而两者可能由同一种病理生理机制所致。主要的异常可能是十二指肠对胃排
Vagus nerve dissection after diarrhea is now rare, due to peptic ulcer and more use of highly selective vagotomy instead of vagotomy and drainage. Because there is no standard definition, the estimated incidence of diarrhea after vagotomy is quite different. Severe diarrhea can be diagnosed only when diarrhea complication (Visick III-IV) or watery diarrhea (more than three times per day) with urgency or fecal incontinence affects normal life and social activities of the patient. The incidence of severe diarrhea is reported to be 0.5 to 8% with an average of 4%. Etiology: Diarrhea after vagotomy is often associated with dumping syndrome, and the liquid diet combined with rapid emptying, so both may be caused by the same pathophysiological mechanism. The main anomaly may be the duodenum to the stomach
