You are watching: Surgical repair of a bile duct medical term

StatPearls . Treasure Island (FL): StatPearls Publishing; 2021 Jan-.


Continuing education and learning Activity

Injuries come the bile duct are almost universally iatrogenic and occasionally are as result of trauma. The most usual procedure leading to bile duct injury is the laparoscopic cholecystectomy. Before the advent of laparoscopic cholecystectomy, open cholecystectomy was used and was associated with a 0.1 come 0.2 percent danger of bile duct injury. Through the development of laparoscopic cholecystectomy, the incidence has increased come 0.4 to 0.6 percent. This task illustrates the evaluation and also management of bile duct injuries and the species of repair accessible and highlights the duty of the interprofessional team in managing patients who undergo bile duct repair.

Injuries come the bile duct are nearly universally iatrogenic and might infrequently be due to trauma.<1> The most common procedure causing a bile duct injury is laparoscopic cholecystectomy. In history the incidence that bile duct injury while performing an open up cholecystectomy was together low together 0.1% to 0.2%, however with the advent of laparoscopic cholecystectomy, the incidence has actually increased come 0.4% come 0.6% the patients.<2> Laparoscopic cholecystectomy performed because that acute cholecystitis and more so because that gall bladder empyema or gangrenous cholecystitis, has a higher chance that bile duct injury.<3><4> Any significant bile duct injury might result in significant morbidity, enhanced mortality, and also financial burden on the patient.<5> this injuries should be prevented with meticulous an approach and selective use of intraoperative cholangiography. The most common an approach to repair significant bile duct injuries is the Roux-en-Y hepaticojejunostomy (RYHJ).

Anatomy and also Physiology

Biliary anatomy and its vascular supply can be variable, i m sorry may lead to inadvertent injury or confusion throughout reconstruction.

Normal Biliary Anatomy

Extra-hepatic right and left hepatic bile ducts join at the hilar plate anterior come the best portal vein to kind the usual hepatic duct (CHD) i m sorry is 1 come 4 cm long and also approximately 4 mm in diameter. It i do not care the usual bile duct (7 to 11 centimeter long and 5 come 10 mm in diameter) after providing off the cystic duct come the gallbladder. The common bile duct enters the second portion of the duodenum v the sphincter of Oddi, a muscular framework that controls the flow that bile right into the duodenum.

The common bile duct most generally joins the main pancreatic duct external the duodenal wall and traverses it together a solitary duct.

Cystic Duct Anatomy

Variations take place in as plenty of as 40% that patients, and it is crucial to identify these together they might predispose come a bile duct injury during surgery. Important variations incorporate the cystic duct circling anterior or posterior come the common hepatic duct before its insertion (occurs in 5% the patients), cystic duct draining into a ideal posterior hepatic duct (occurs in 0.6% come 2.3% that patients), and accessory ducts that Luschka (occurs in 15 to 30% that patients).

Right Hepatic Ductal System

Normal anatomy is existing in 57% the patients. The appropriate hepatic duct is a union that the appropriate anterior and posterior sectoral ducts in typical patients. Typical variations include drainage the the best posterior sectoral duct into the left hepatic duct (occurs in 20% that patients); drainage of the best anterior sectoral duct into the left hepatic duct (occurs in 6% of patients); and low insertion of the best hepatic or appropriate sectoral duct into the common hepatic or cystic duct (known to increase iatrogenic hazard of common bile duct injury during laparoscopic cholecystectomy).

Left Hepatic Ductal System

Normal anatomy is existing in 67% of the populace and is described as the junction of the left lateral and also medial sectoral ducts to kind the left hepatic duct.

Biliary Blood Supply

The blood supply to the common bile duct and the usual hepatic duct is provided by 2 small arteries that travel along the lateral borders of the ducts at the 9 and also 3 o"clock positions. These space branches of the appropriate hepatic and cystic arteries superiorly and also the posterior superior pancreaticoduodenal and gastroduodenal arteries inferiorly. The 2 arteries hold together and kind a plexus on the surface of the bile ducts. The supra-duodenal usual bile duct is the many prone to ischemia as result of the relatively poor blood supply when contrasted to the distal typical bile duct. Arterial variants are common, and also consist of a replaced right hepatic artery from the superior mesenteric artery and a replaced left hepatic artery native the left gastric artery.


The indications for bile duct repair space dependent top top the mechanism, temporal recognition, and classification that the bile duct injury. The type of injury and its time of acknowledgment will identify if and when an procedure is required.

The other occasions when these methods come in handy room while performing elective surgeries for gall bladder cancer (requiring resection the hepatic ducts), hepatic resections, or hepatic transplants.<6>

Bismuth-Strasberg Classification 

This is the most typical system used (Type A to E; E1 to E5)<7>

Timing of Recognition (determines management)

Intraoperative acknowledgment should frequently prompt immediate surgical repair together this confers the ideal outcomes; however, much less than 40% of bile duct injuries are recognized at the index operation. Stewart and also Law reviewed bile duct repair done by specialists and general surgeons and also found that only 17% of patients repaired through the basic surgeon had a favorable outcome.<8> Bile duct injuries have to not be underestimated. If the surgeon is inexperienced, an intraabdominal drainpipe should it is in placed, and also the patient have to be immediately transferred to a hepatobiliary specialist.

Early postoperative biliary injury acknowledgment (typically in ~ 24 come 48 hours) in a steady patient without signs of sepsis might be repaired immediately.

Accessory duct injury: If the hurt duct is less than 3 mm, the duct can be ligated; if better than 4 mm, it calls for operative repair. Bigger ducts typically tend to it is in sectoral ducts and require repair.
Lateral injuries to a significant duct without thermal injury (Type D): main suture repair over a T-tube
CHD transections greater than 2 cm away native bifurcation and the hurt segment is less than 1 cm long (Type E1): Can think about end to finish anastomosis v a T-tube at a various site
