Motility of the Roux-en-Y hepaticojejunostomy in asymptomatic patients

Abstract

In asymptomatic patients, interdigestive motility is present in the hepaticojejunostomy Roux-en-Y limb, but it is abnormal because of slow migration of phase IIIs. The second abnormality observed in the limb is a response to meals that is both short and of low amplitude.

Utility of hepatobiliary scintigraphy for recurrent reflux cholangitis following choledochojejunostomy: A case report

“…Another mechanism is that the once the jejunum is transected, as is commonly performed, its motility and electrical activity are greatly affected. This can cause reverse peristalsis [7] , and as a result, the intestinal contents can become stagnant, thus favoring bacterial colonization and leading to postoperative cholangitis and abnormal liver function [8] . Finally, a motility disorder might arise in the mobilized Roux-en-Y loop, allowing the intestinal contents to reflux [9] .…”

Hepatic ductoplasty for iatrogenic Bismuth type 2 bile duct stricture: A case report

“…The etiology of reflux cholangitis is considered to be biliary stasis with bacterial infection due to stenosis or dysfunction of the reconstructed jejunal loop, including denervation, kinking, and/or disuse atrophy [[10], [11], [12]]. This condition eventually leads to formation of biliary stones.…”

Case-control study of the efficacy of retrogastric Roux-en-Y choledochojejunostomy

“…In Roux-en-Y biliary-enteric anastomosis the jejunum is usually transected, and its motility and electrical activity are greatly impacted. This can cause reverse peristalsis [ 29 ], and as a result, the intestinal contents can become stagnant, thus favoring bacterial colonization and leading to postoperative cholangitis and abnormal liver function [ 30 ]. Due to the weight of the transverse colon and the gastric antrum, the pylorus and duodenum can be compressed in choledochojejunostomies performed using the antegastric route.…”
