and continues as the common bile duct. Extrahepatic bile ducts, common hepatic duct and common bile duct, receive their blood supply from below from the gastroduodenal artery or the proper hepatic artery [2] via two longitudinal arteries which run along the length of the bile duct at 3 and 9’0 clock positions and from above from the caudate artery and the medial subsegmental artery of segment IV via an arterial network present in the hilum of the liver [3]. In the case of a bile duct injury, the blood supply from below has been interrupted and the only blood supply to the bile ducts is from the hilum. For this reason, even in a Bismuth Type I or II BBS, the common hepatic duct stump though present has poor blood supply and is not suitable for anastomosis.


Discussion
The biliary-enteric anastomosis for benign biliary stricture is thus different from other biliary-enteric anastomosis as follows: i. Choledocho-duodenostomy (Figure 1) for stone disease where the infra-cystic supra-duodenal part of the common bile duct is anastomosed to the first part of the duodenum.
ii. Hepatico-jejunostomy (Figure 2) in pancreatoduodenectomy or after excision of a choledochal cyst where the common hepatic duct above the cystic duct but below the hilum is anastomosed to a Roux-en-Y loop of jejunum.
iii.Porto-enterostomy (Figure 3) for extra-hepatic biliary atresia where the liver capsule around the porta hepatis containing openings of multiple intrahepatic bile ducts is anastomosed to a Roux-en-Y loop of jejunum.
iv. Cholangio-jejunostomy (Figure 4) for high biliary block e.g.hilar cholangiocarcinoma [4] or gall bladder cancer [5] where an intra-hepatic bile duct, most commonly of segment III, is anastomosed to a Roux-en-Y loop of jejunum.
v. Longmire procedure, again for the high biliary block where a part of the left lateral segment of the liver is resected

Background
Gall stone disease is common all over the world; cholecystectomy is one of the commonest operations performed by a general surgeon.Bile duct injury is a not uncommon complication of cholecystectomy and the risk of bile duct injury is at least 2-3 times more during laparoscopic than during open cholecystectomy, the incidence being around 0.5%.
Bile duct injury during cholecystectomy may result in an iatrogenic benign biliary stricture.Benign biliary strictures are classified from Bismuth Type I to Type V depending upon the length of the common hepatic duct stump and patency of the biliary ductal confluence as follows The gold standard of management of benign biliary stricture is surgical repair in the form of a biliary enteric anastomosis.Biliary enteric anastomosis for benign biliary stricture, irrespective of its Bismuth Type, should be at the hilum of the liver.The hilar plate needs to be lowered in order to expose the extra-hepatic horizontal part of the left hepatic duct at the base of the quadrate lobe (segment IV).The ductotomy should extend across the hilum (biliary ductal confluence) into the left hepatic duct-the Hepp Couinaud approach [1].
We want to suggest a new name for the biliary-enteric anastomosis performed for benign biliary stricture.

Surgical anatomy
Right and left hepatic ducts unite at the hilum of the liver to form the common hepatic duct which is joined by the cystic duct

What's in a name? Hilo-Jejunostomy, not Hepatico-Jejunostomy, for Post Cholecystectomy Iatrogenic Benign Biliary Stricture
Copyright: © 2016 Kapoor hilar cholangiocarcinoma.Following the same nomenclature, we propose that the biliary-enteric anastomosis for postcholecystectomy benign biliary stricture which should be performed at the hilum (confluence of right and left hepatic ducts and extending into the left hepatic duct) should be called 'hilojejunostomy' (Figure 5) to differentiate it from other biliaryenteric anastomoses including hepaticojejunostomy.      so that the intrahepatic ducts of segments II and III are exposed; the cut surface of the liver is then anastomosed to a Roux-en-Y loop of jejunum.In a modification, the exposed intrahepatic ducts are anastomosed to the Rouxen-Y loop of jejunum [6].

Proposal
Cholangiocarcinoma arising from the bile ducts at the hilum (confluence of right and left hepatic ducts) is called Type I Common hepatic duct stump >2 cm Type II Common hepatic duct stump <2 cm Type III No common hepatic duct stump but biliary ductal confluence patent Type IV Biliary ductal confluence not patent (right and left hepatic ducts separated) Type V Stricture involving an aberrant duct
