Hydrostatic balloon dilatation has been used successfully to treat several patients with stomal stenosis occurring as a late complication of gastroplasty. The technique of hydrostatic balloon dilatation practiced in this institution is reviewed in detail. This technique appears to offer several advantages over previous techniques: 1) the procedure can be accomplished with intravenous sedation eliminating the need for general anesthesia; 2) trauma to the gastric channel is minimized because no attempt is made to manipulate the endoscope through the stoma into the distal stomach; 3) radiopaque markers on the polyethylene balloon catheter permit easy and accurate positioning of the balloon within the gastric channel; 4) the low compliance characteristics of the polyethylene balloon used permit inflation to a predetermined outer diameter with minimum risk of balloon deformity or overdistention and rupture; and 5) the procedure is easily standardized and can therefore be expected to yield reproducible results. Late stomal stenosis after gastric partitioning may respond to conservative therapy including nutritional support and dietary counselling. Hydrostatic balloon dilatation should be considered as the preferred method of stomal dilatation in patients refractory to alternative forms of management.
水压球囊扩张术已成功用于治疗数例胃成形术后迟发性并发症——吻合口狭窄的患者。本文详细回顾了本机构所采用的水压球囊扩张技术。该技术相较于以往技术似乎具有诸多优势：1）该操作可在静脉镇静下完成，无需全身麻醉；2）对胃通道的创伤降至最低，因为无需尝试通过吻合口将内镜插入远端胃；3）聚乙烯球囊导管上的不透射线标记便于在胃通道内轻松、准确地定位球囊；4）所用聚乙烯球囊的低顺应性特性允许将其充气至预定外径，球囊变形、过度扩张及破裂的风险最小；5）该操作易于标准化，因此有望产生可重复的结果。胃分隔术后的晚期吻合口狭窄可能对包括营养支持和饮食咨询在内的保守治疗有反应。对于对其他治疗方式无效的患者，水压球囊扩张术应被视为吻合口扩张的首选方法。
