The Approach of Biliary Drainage in Hepatolithiasis Patients With Sphincter of Oddi Laxity

Study Overview
=================
Brief Summary
-----------------
Residual and recurrent stones remain one of the most important challenges of hepatolithiasis which is reported in 20% to 50% of patients treated with these therapies. Up to now the most two common surgical procedures performed were choledochojejunostomy and T tube drainage as biliary drainage in hepatolithiasis. The goal of the present study was to evaluate the therapeutic safety, and perioperative and long-term outcomes of choledochojejunostomy versus T tube drainage for hepatolithiasis with sphincter of Oddi laxity.

Detailed Description
-----------------
Background: SOL results in reflux of duodenal fluid and enteric bacteria infection, which lead to the formation of stones in the biliary tract. Roux-en-Y hepaticojejunostomy (HJ) shows considerable advantage for prevention of reflux of intestinal content into the bile duct. As a result, A randomized controlled trial (RCT) evaluate the therapeutic safety, and perioperative and long-term outcomes of HJ versus T tube drainage for hepatolithiasis with SOL. Intervention: In total, 210 patients who met the following eligibly criteria were included and were randomized to choledochojejunostomy arm or T tube drainage in a 1:1 ratio. Clinical data include: the incidence of biliary complications (stone recurrence; biliary stricture; cholangitis); sphincter of oddi function; biliary leakage; mortality; hepatic injury; quality of life.

Interventional Model Description: Patients were randomized to choledochojejunostomy arm or T tube drainage arm
Masking: Double


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: T-tube drainage<br>The T-tube was placed for biliary drainage | Procedure: T-tube drainage<br>* The T-tube was placed for biliary drainage and the common bile duct was intermittently sutured with 4-0 vicryl sutures.<br>|
| Experimental: Roux-en-Y Hepaticojejunostomy<br>biliary-enteric anastomosis was performed | Procedure: Roux-en-Y Hepaticojejunostomy<br>* The common hepatic duct was cut and the duodenal side is closed by suture. The small intestine was cut off 15 cm below the ligament of Treitz. The distal end was lifted, and a 1-2 cm incision was made at the jejunal wall 4-5 cm from the jejunal stump. The anastomosis is used a 5-0 PSD Ⅱ suture, with double needles, inside-out in the jejunum and outside-in in the hepatic duct. One side of needles was used to continuely penetrate and suture the whole layer of the posterior-lateral wall of the jejunum, the posterior-lateral wall of the biliary duct, and the other side of needles was used to continuely stuere the anterior part of the anastomosis. Mucosa-to-mucosa contact should be ensured with every stitch.The anastomotic stomas were then checked for leakage. Enteric-enteric anastomosis was performed 60 cm below the site of the hepatojejunal anastomosis.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| stone recurrence rate | A recurrence stone was defined as a stone detected more than 3 months after surgery by any diagnostic method. (%) | 3 years | 
| biliary stricturer rate | Biliary stricture defined as clinically evident stenosis and subclinical stenosis proved by endoscopic examination or reoperation (%) | 3 years | 
| Cholangitis rate | The diagnosis of cholangitis is based on clinically evident (abdominal discomfort/pain, jaundice or fever associated with hepatolithiasis (%) | 3 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| sphincter of oddi function | Grading criteria for the SO function were as follows: Normal; Laxity and Loss of function | an expected average of 120 minutes | 
| Mortality | Operative mortality was defined as any death resulting from a complication during surgery | 90 days | 
| Biliary leakage | Biliary leakage was documented in line with the International Study Group of Liver Surgery (ISGLS) definitions and grading systems | 90 days | 
| total bilirubin | serum total bilirubin on 3 postoperative day (umol/L) | 90 days | 
| quality of life grading | Quality of life will be assessed by Visick score (Ⅰ～Ⅳ). | 3 years |
