- Endoscopic retrograde cholangiopancreatography (ERCP) is the primary treatment modality for bile duct obstruction. When ERCP is unsuccessful, percutaneous transhepatic biliary drainage can be an alternative method. Endoscopic ultrasound-guided biliary drainage (EUS-BD) has emerged as a treatment option for biliary obstruction, especially after ERCP failure. EUS-BD offers transluminal intrahepatic and extrahepatic drainage through a transgastric and transduodenal approach. EUS-guided hepaticogastrostomy (EUS-HGS) is an excellent choice for patients with hilar strictures or those with a surgically altered anatomy. The optimal steps in EUS-HGS are case selection, bile duct visualization, puncture-site selection, wire insertion and manipulation, tract dilation, and stent placement. Caution should be taken at each step to prevent complications. Dedicated devices for EUS-HGS have been developed to improve the technical success rate and reduce complications. This technical review focuses on the essential practical points at each step of EUS-HGS.

Abstract

- Portoenteric fistula is a rare cause of massive upper gastrointestinal bleeding. Most cases can be treated with radiointervention or surgery, but portoenteric fistula is associated with a high mortality. We reported a case of intermittent massive upper gastrointestinal bleeding in a 33-year-old man with cholangiocarcinoma who underwent surgical resection followed by chemoradiation. A portoduodenal fistula due to chronic duodenal ulceration was identified. The bleeding was successfully controlled by endoscopic ultrasound-guided coil placement through the duodenal bulb using the anchoring technique. Follow-up endoscopy and computed tomography scan showed multiple coil placements between a part of the portal vein and the duodenal bulb without any evidence of portal vein thrombosis. There were no complications, and bleeding did not recur during the 8-month follow-up period.

- Tracheoesophageal fistulas (TEFs) have traditionally been managed surgically, but the endoscopic approach is widely performed as a less invasive alternative. Different closure techniques have been proposed with inconsistent results. An over-the-scope clip (OTSC) appears to be a reasonable option, but long-term results have not been well defined. We report the long-term outcomes of a complex case of successful closure of a benign refractory TEF using an OTSC after failed surgical management and esophageal stent placement.

 - Background
/Aims: The mechanical properties of biodegradable stent when fabricated using different number of pins per row of fabrication has been limited. We compared the radial compressive force of polydioxanone (PDO) stent that was fabricated in hook and cross manner, using 13, 17 and 19 pins per row and measure the radial compressive force and ex vivo deployment.
Methods
The PDO stents fabricated by the in-house aluminum mandrel were tested for radial force using plate compression until the stent achieved 50% strain. The relationship between compression force and %strain was calculated. Ex vivo testing of stent expansion against short segment stricture was performed in a pig small intestine compared between PDO hook cross PDO stent and braided metallic stent.
Results
The stent shortening of 16.40%, 31.20% and 19.24% was observed in 13-, 17- and 19-pin-per-row, respectively. The maximum force to achieve 50% strain were 0.503, 1.168 and 1.008 N for 13, 17 and 19 pins per row, respectively. The stent fabricated using hook and cross pattern demonstrated higher conformability to anatomical stricture when compared with braided stent.
Conclusions
PDO stent fabricated using 17 pins per row demonstrated highest radial force when compared with 13 and 19 pins per row.
