Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Roux-en-Y hepaticojejunostomy is the standard procedure used by most hepatobiliary surgeons for biliary reconstruction following iatrogenic bile duct injury, benign and malignant CBD strictures, choledochal cysts and biliary tract tumors management. The incidence of anastomotic stricture following hepaticojejunostomy in experienced centers ranges between 5%-22%. Hepaticojejunostomy stricture is a serious complication of biliary surgery, if untreated, can lead to repeated cholangitis, intrahepatic stones formation, biliary cirrhosis, hepatic failure and eventually death.

Revision of hepaticojejunostomy is a complex procedure, the surgical procedure being made difficult by the sequelae of long-standing unrelieved biliary obstruction like portal hypertension due to secondary biliary cirrhosis, atrophy of liver lobes and presence of cholangiolytic liver abscess.

Endoscopic management is not only the least invasive but also very effective via either balloon dilatation or stenting of the stricture. In patients with "Roux-en-Y" hepaticojejunostomy, the endoscopic access to the anastomosis is hampered by the distance traveled by the jejunal loop until reaching the angle of the enteral anastomosis.

Many modifications of hepaticojejunostomy to provide permanent endoscopic access have been described in the literature including duodenal, gastric and subcutaneous access loops.

Gastric access loop was first described by Sitaram et al. Ten patients had undergone gastric access loop. Access loop was entered easily with the gastroscope in five patients in whom it was attempted. In a series with 16 cases, Hamad MA and El-Amin H assessed different construction of gastric access loop in the form of bilioenterogastrostomy the overall success rate of endoscopic access to the HJ through the three types of BEG was 87.5%, while it was 100% for BEG type III, which is a construction similar to the previous series (BEG) type.

Subcutaneous loop access was described by Chen et al. and by Huston et al. In Hutson's series of 7 patients, recurrent strictures were treated with repeated balloon dilations. The stone extractions were all successful. In most series, the subcutaneous loop was used for management os HJ stricture and intrahepatic stones by radiologic intervention. Recently the subcutaneous loop can be used as an endoscopic biliary access.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is a prospective randomized controlled study; which will include all patients who will undergo Roux-en-Y hepaticojejunostomy reconstruction during the period from 9-2017 to 12-2019.

\* Methodology:

Patients will be randomized into three groups according to the surgical procedure performed as follows:

* Group A: Patients undergoing modified hepaticojejunostomy with gastric access loop
* Group B: Patients undergoing modified hepaticojejunostomy with subcutaneous access loop
* Group C: Patients undergoing standard hepaticojejunostomy with no endoscopic access loop

* Pre-operative preparation:

For all patients, full medical history, clinical examination, laboratory investigations in the form of complete blood count (CBC), prothrombin time and concentration (PTT), liver function tests (LFT) and kidney function tests (KFT) will be performed.

Imaging studies will also be carried out in the form of abdominal ultrasonography (US), computerized tomography scan (CT) of the abdomen and magnetic resonance cholangiography (MRC) if indicated.

ERCP will be performed, whenever applicable, whether for diagnosis or therapeutic trial.

\* Surgical Technique:

For gastric access loop:

* Surgical technique: under general intubation anesthesia, a generous right subcostal incision is performed and could be extended on demand upward to the xiphoid process and/or to the left subcostal area. Thorough dissection and adhesiolysis is performed to reach the CBD and prepare the unaffected proximal part for anastomosis. The Roux jejunal loop is prepared and passed retrocolic to reach the porta hepatis.
* Then, the hepaticojejunostomy is done via end to side anastomosis using interrupted sutures of polyglactin of 3-0 or 4-0 size. The anastomosis is done 10-15 cm away from the free distal end of the Roux jejunum loop to allow anastomosis without tension to the stomach. A biliary stent may be optionally placed according to operative circumstances and is brought out through the anterior abdominal wall.
* The end of the Roux jejunal loop taken up for hepaticojejunostomy is not closed but is anastomosed to the anterior wall of the gastric antrum near the pyloric orifice.
* All the enterogastrostomies and enteroenterostomies were in the form of single-layer continuous sutures of polyglactin of 3-0 size. An intraperitoneal drain was left in the hepatorenal pouch before closing the incision.

For subcutaneous access loop:

In the subcutaneous access loop, the same steps are done for performing roux-en-Y hepaticojejunostomy.

The closed free end of roux loop is passed through the anterior abdominal wall in the right subcostal area and then fixed to the wall in a subcutaneous position using 3/0 polyglactin sutures. The limb between the hepaticojejunal anastomosis and the subcutaneous fixation should be short and straight.

Four Ligaclips are used to mark the jejunal loop by clipping the sutures holding the access loop in place.
