Roux-en-Y enteric diversion is useful for correction of alkaline reflux gastritis consequent to loop gastro-enterostomy, in the treatment of spontaneous enterogastric reflux and esophagitis, and in the configuration of primary peptic ulcer surgery. Construction of the Roux-en-Y, however, may be technically difficult or hazardous and is time consuming. Conversion of a loop gastroenterostomy into Roux-en-Y topology by umbilical tape ligation of the afferent limb and jejunojejunostomy was reported by A. Hamblin Letton in 1978. With the availability of stapling devices, the Letton procedure acquires new significance as an attractive alternative to the classic Roux-en-Y.
Roux-en-Y肠转流术可用于纠正因袢式胃-肠吻合术导致的碱性反流性胃炎，治疗自发性肠胃反流和食管炎，以及用于原发性消化性溃疡手术的构建。然而，Roux-en-Y的构建在技术上可能困难或具有危险性，且耗时较长。1978年，A. 哈姆布林·莱顿报道了通过用脐带来结扎输入袢并进行空肠-空肠吻合术，将袢式胃-肠吻合术转变为Roux-en-Y术式。随着吻合器的出现，莱顿手术作为经典Roux-en-Y术式有吸引力的替代方法，获得了新的意义。
