Summary

Objective: Evaluate the role of Roux-en-Y hepaticojejunostomy (RYHJ) in hepatolithiasis patients with sphincter of Oddi laxity (SOL). Summary Background Data: Hepatolithiasis poses high risks of residual, recurrence, and re-intervention. SOL significantly impacts this condition. RYHJ has been recommended for hepatolithiasis concomitant SOL but without prospective evidence. Methods: This is an open-label randomized controlled trial recruiting patients with hepatolithiasis concurrent SOL. Patients were randomly assigned (1:1) to undergo RYHJ or not. The primary endpoint was stone occurrence, including residual and recurrence, within a three-year postoperative period. Secondary endpoints incorporated perioperative and long-term outcomes, like episodes of cholangitis and invasive re-interventions for stones and related complications. The analyses followed the intention-to-treat principle.

Conditions

• Hepatolithiasis
• Sphincter of Oddi Dysfunction

Interventions

Type	Name	Description
PROCEDURE	Roux-en-Y hepaticojejunostomy	All participants received routine perioperative care and followed the same surgical principles: removing affected liver segments, clearing stones, correcting strictures, and then restoring bile drainage. The primary indications for hepatectomy were unilobar or segmental diseases and the presence of the following lesions in the affected liver segment or lobe: 1) multiple stones with biliary strictures that cannot be cured via choledochoscopy, 2) atrophy, fibrosis, and multiple abscesses, and 3) suspicious neoplasia. Biliary exploration was routinely conducted to facilitate stone removal, rectify strictures, and assess the functionality of the Oddi sphincter. Following this, patients would be evaluated for eligibility and assigned accordingly. The sole distinction between the two arms was performing RYHJ or maintaining the common bile duct for bile drainage.
