Primary bile reflux gastritis: which treatment is better, Roux-en-Y or biliary diversion?

Primary bile reflux gastritis is an unusual and elusive problem. Postgastrectomy bile reflux has been long recognized and treated variously with Roux-en-Y gastrojejunostomy, Braun enteroenterostomy, and Henley jejunal interposition. All of these procedures have been fraught with postoperative side effects, the worst of which is stasis. A new procedure utilizing biliary diversion has been proposed to divert bile from the gastric lumen without vagotomy or gastric resection. This procedure was used for 16 patients with diagnosed bile reflux, and results were compared with those of a previous group of 21 patients who had been treated with Roux-en-Y gastrojejunostomy. The patient groups were similar in age, sex, weight, symptoms, and results of investigative studies. The earlier group all had vagotomy, antrectomy, and gastrojejunal anastomosis to a 45-cm Roux limb. The later group all had an end-to-side choledochojejunostomy to a 45-cm Roux limb, taken 45 cm from the ligament of Treitz. The patients in the bile diversion group had fewer complications and shorter hospital stays. In addition, they had few postoperative complaints, no further operations for either bile reflux or upper gastrointestinal stasis, and no long-term deaths due to gastrointestinal problems or malnutrition. Their eventual postoperative gastric emptying improved significantly when compared with the Roux-en-Y patients, suggesting that the dysmotility observed preoperatively may well have been a result of the bile injury to the stomach, rather than an underlying gastric dysmotility.
