Biliary diversion. A new method to prevent enterogastric reflux and reverse the Roux stasis syndrome.

OBJECTIVE: To design an operation to prevent enterogastric reflux of bile that will not interfere with gastric or proximal intestinal motility and that will be applicable in patients with primary alkaline reflux gastritis, various prior ulcer operations, and previous corrective operations for enterogastric reflux.

DESIGN: A nonrandomized, prospective review of 27 patients with enterogastric reflux operated on between 1991 and 1995.

SETTING: A midwestern medical school and 400-bed tertiary referral center, adult hospital.

PATIENTS: Twenty-seven patients with symptoms compatible with enterogastric reflux, primary or secondary to ulcer operations, or with Roux-en-Y limb stasis following attempts to correct alkaline reflux gastritis.

INTERVENTIONS: An operation designed to reestablish gastroduodenal continuity by converting previous procedures such as Billroth II gastrectomy and Roux-en-Y gastrojejunostomy to a Billroth I gastroduodenostomy, and by diverting bile away from the stomach by end-to-side choledochojejunostomy by means of a Roux-en-Y limb of 35 to 40 cm.

MAIN OUTCOME MEASURES: Resolution of the preoperative symptoms of pain, nausea, and bilious vomiting in patients with enterogastric reflux, and elimination of the Roux stasis syndrome as well as prevention of future enterogastric reflux in patients undergoing conversion from Roux-en-Y to Billroth I. Serial evaluation of gastric emptying after conversion to a Billroth I configuration to determine whether dysmotility is improved or eliminated.

RESULTS: Symptoms were completely resolved in 22 of the 26 surviving patients, with follow-up of 6 months to 4 years. None of the 26 patients have had any bilious vomiting postoperatively. Roux-en-Y stasis has been corrected when due to a mechanical problem (eg, strictures, marginal ulcers), although thus far normal gastric emptying has not been observed in all of these multiply surgically treated patients.

CONCLUSIONS: Enterogastric reflux is common following most ulcer operations. Attempted correction of this problem may result in other difficulties, including delayed emptying due to Roux-en-Y stasis. The fact that most patients with enterogastric reflux are female suggests that this condition is related to disordered motility; therefore, vagal interruption and major gastric resections should be carefully considered to avoid future disabling problems.
