The purpose of this study is to determine whether Roux-en-Y choledochojejunostomy is a more effective treatment for the hepatolithiasis patients accompanied with Sphincter of Oddi Loose.

Condition Intervention
Hepatolithiasis Sphincter of Oddi Laxity Procedure: Roux-en-Y choledochojejunostomy

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Randomized Controlled Trial of Treating Hepatolithiasis(Accompanied With Sphincter of Oddi Laxity) With Roux-en-Y Choledochojejunostomy

Further study details as provided by TingBo Liang, Zhejiang University:

Primary Outcome Measures:
  • recurrence rate of hepatolithiasis [ Time Frame: within five years after the operation ]

Estimated Enrollment: 100
Study Start Date: October 2011
Estimated Study Completion Date: November 2020
Estimated Primary Completion Date: November 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Control Group
Just clear the stone without choledochojejunostomy
Experimental: Experimental Group
Clear the stone combined with Roux-en-y choledochojejunostomy
Procedure: Roux-en-Y choledochojejunostomy
Roux-en-Y choledochojejunostomy must be operated

Detailed Description:
Hepatolithiasis (HL) is prevalent in East Asia, especially in China. While this condition results from multiple etiological factors, obstructive cholangitis is usually the main cause. In our clinical experience, the investigators have found few cases with obstruction of the common bile duct or sphincter of Oddi; to the contrary, almost half of our clinical cases showed sphincter of Oddi laxity (SOL). SOL results in reflux of duodenal fluid and Escherichia coli (E. coli) infection, which lead to the formation of stones in the biliary tract. Thus, HL tends to recur in SOL patients. For these patients, Roux-en-Y choledochojejunostomy(choledochojejunostomy with an anti-reflux ansa intestinalis) may be the most promising therapy.

Ages Eligible for Study:   14 Years to 80 Years   (Child, Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • diagnosed as hepatolithiasis
  • sphincter of oddi laxity is diagnosed during operation
  • sign the informed consent form voluntary
  • can cooperate well with the followup
  • anticipated to be tolerant of Roux-en-Y choledochojejunostomy

Exclusion Criteria:

  • already underwent choledochojejunostomy at past, which make the function of Sphincter of Oddi unable to be evaluated
  • a lot of stones remain in biliary tract after operation, which make the recurrence or progression of hepatolithiasis unable to be evaluated
