Endoscopic ultrasound-guided transgastric biliary drainage after partial gastrectomy

Table of Contents

We report a case of endoscopic ultrasound (EUS)-guided transgastric left intrahepatic bile stent drainage after partial gastrectomy for treating cholangiocarcinoma.

A 56-year-old Chinese woman had a 8-month history of abdominal pain and jaundice. She had a distal gastrectomy because of cholangiocarcinoma a year ago. Both endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic biliary drainage (PTBD) were unsuccessful, so we decided to place a stent under EUS guidance from the remaining stomach to the left intrahepatic bile duct. A left intrahepatic bile duct puncture was made with a 19 G needle. A 0.035-inch yellow, zebra guide wire was introduced through the EUS needle and advanced in an antegrade fashion ([Fig. 1]).

Afterward, 7 Fr, tapered, biliary, and dilator catheters were inserted over the guide wire and removed, in that order, to dilate the tract. The needle was withdrawn, and an 8.5 F, plastic, single pigtail stent was placed. White bile juice flowed out from the stent ([Fig. 2]).

The procedure was successful and no complications were observed. After a week, the total bilirubin decreased by nearly half. A computed tomography (CT) scan showed that the stent was not displaced ([Fig. 3]).

In 1996, Wiersema [1] performed EUS-guided cholangiography in seven patients. EUS-guided puncture of the left hepatic ducts via the stomach has been done for cholangiography or in the rendezvous technique. In the present patient we used an 8.5 Fr, plastic, single pigtail stent for 6 months. It was proposed that the plastic stent could be replaced by a covered metallic stent if there was recurrence of the jaundice. Similarly to Vila et al. [2], the main difficulty we found during the exploration was to dilate the gastric wall orifice. This might be due to fibrotic changes in the gastric remnant. In this situation, we found it relatively easy to use hot wire probe hybrid current to expand the puncture point before enlarging the fistula. In our opinion, this technique is a good alternative when ERCP and PTBD are unsuccessful. The limitation is the right hepatic ductal system cannot be fully drained.
