ABSTRACT

PURPOSE:

To present an option technique during the accomplishment of a "Roux-en-Y" hepaticojejunostomy that, allows future transgastric endoscopic access to the biloenteric anastomosis.

METHODS:

The side-to-side "Roux-en-Y" hepaticojejunostomy is carried through transmesocolic, retrogastric short tunnel. A distal jejunal loop of approximately 10,0 to 15,0 cm must be kept far from the anastomosis that allows its setting, without tension, in the anterior gastric wall bellow the small bending, between body and of the stomach antrum. Once the jejunal segment is fixed on the anterior gastric wall, this will allow future endoscopic access to the bilioenteric anastomosis, carried through transgastric punction guided by endoscopic-ultrasound (EUS).

CONCLUSION:

The modified "Roux en Y" hepaticojejunostomy is a simple and new technique to permit an alternative transgastric endoscopic access to bilioenteric anastomosis.

Key words: Biliary anastomosis; surgical technique; endoscopy

Introduction

There are several indications for performing "Roux-en-Y" hepaticojejunostomy such as, bile duct injury, malignant strictures, benign strictures, multiple gallstones and liver transplantation1. Once performed, it can develop complications such as postoperative bile duct strictures, intra hepatic gallstones and chronic cholestasis. The outcome of patients if not treated will be acute cholangitis, hepatic fibrosis, and in more advanced cases secondary biliary cirrhosis and liver failure2 , 3.

Therapeutic options involve reoperation of the biliary tract, endoscopic procedures or interventional radiology, often difficult due to intrahepatic multiple surgical anastomoses4. To facilitate access to the biliary tract in cases of recurrence of stenosis the strap to the hepaticojejunostomy can be attached in the abdominal wall to permit further endoscopic approach to the biliary-enteric anastomosis. Also described is the double balloon endoscopy or, an alternative endoscopic approach such as, video-assisted laparoscopy4 , 5. Another option is an interventional radiology with trans-hepatic access to the biliary tract6 , 7.

Many of these procedures depend on the logistics of advanced radiology, generate discomfort to the patient in cases of ostomy or rely on more invasive and repeated biliary surgical procedures4 , 5 , 6 , 7.

The objective of this work is to, describe an optional technique during the accomplishment of a "Roux-en-Y" hepaticojejunostomy that, allows future transgastric endoscopic access to the biliary-enteric anastomosis.

Methods

Surgical technique

The side-to-side "Roux-en-Y" hepaticojejunostomy is carried through transmesocolic, retrogastric short tunnel. A distal jejunal loop of approximately 10,0 to 15,0 cm must be kept far from the anastomosis that allows its setting, without tension, in the anterior gastric wall bellow the small bending, between body and the stomach antrum (Figure 1).

Once the jejunal segment is fixed on the anterior gastric wall, this will allow future endoscopic access to the bilioenteric anastomosis, carried through transgastric punction guided by endoscopic-ultrasound (EUS) which facilitates identification of the strap attached to the gastric body (Figure 2).

Discussion

Patients who develop complications of hepaticojejunostomies such as anastomotic stenosis are difficult to treat. The recurrent bouts of cholangitis due to chronic cholestasis and intrahepatic stones are the main cause of progressive loss of liver function. In these cases the performance of a new biliary-enteric anastomosis is the most widely used therapeutic option. However, the high anastomosis in hilar and intrahepatic board, have high morbidity and mortality, with complication rates of up to 43%2. Recurrence of stenosis is common in about 25% of cases and will require further intervention. Two-thirds of recurrences occur within two years and 90% within five years8 , 9.

Less invasive treatment options that can be performed repeatedly are of great value in the complications of "Roux-en-Y" hepatojejunostomies. Currently among these options have interventional radiology and endoscopic therapies have been used more frequently. Through these you can unclog and wash the bile, dilate stenosis and pass transanastomotic stents to treat and prevent cholestasis and further hepatic dysfunction10 , 11.

While through the trans-hepatic approach there are complications related to puncture and permanence of external catheters, in patients with "Roux-en-Y", the endoscopic access to the anastomosis is hampered by the distance traveled by the jejunal loop until reaching the angle of the enteral anastomosis5 , 6 , 7.To overcome such problems, innovative endoscopic techniques such as double balloon endoscopy, fixing the jejunal loop of the hepaticojenunostomy in the abdominal wall, invasive laparoscopic video-assisted endoscopic procedures are described. The best approach is selected on a case by case basis2 , 8 , 9.

In this context we propose an alternative approach for accessing the "Roux-en-Y" hepaticojejunostomies that can be performed by ultrasound endoscopy. This simple technique has the advantages related to the absence of ostomies and external catheters, permit repeated endoscopic procedures to access the anastomotic problems with shortened distances through the jejunal loop.

Conclusion

The modified "Roux en Y" hepatojejunostomy is a simple and new technique to permit an alternative transgastric endoscopic access to biliary-enteric anastomosis.
