Efficacy and safety of a novel polytetrafluoroethylene‐coated self‐expandable metal stent for distal malignant biliary obstruction

DEN Open, Volume 5, Issue 1, April 2025.
Abstract Background Stent migration and sludge formation remain significant problems associated with covered self‐expandable metal stents (CSEMSs). The EGIS biliary stent fully covered flare type (EGIS biliary stent), a new type of polytetrafluoroethylene‐coated self‐expandable metal stent with low axial force and an anti‐migration system, was ...

A two-phase two-layer model for transdermal drug delivery and percutaneous absorption [PDF]

Mathematical Biosciences, 257, pp. 96-103, 2014, 2014
One of the promising frontiers of bioengineering is the controlled release of a therapeuticdrug from a vehicle across the skin (transdermal drug delivery). In order to study the complete process, a two-phase mathematical model describing the dynamics of a substance between two coupled media of different properties and dimensions is presented.

Recurrence rate of cholecystitis after initial gallbladder stenting versus secondary gallbladder stenting: A propensity score matching study

DEN Open, Volume 5, Issue 1, April 2025.
Abstract Objective Limitations are sometimes encountered in the application of laparoscopic cholecystectomy to the treatment of acute cholecystitis. Endoscopic gallbladder stenting (EGBS) has emerged as an additional option. However, the long‐term stent patency remains an issue.

Successful treatment of isolated bile leakage after hepatectomy combination therapy with percutaneous transhepatic portal embolization and bile duct ablation with ethanol: a case report

Surgical Case Reports, 2018
Background Bile leakage after hepatectomy still causes relatively serious problems, and some types of bile leakage are intractable. Case presentation We report a case of postoperative isolated bile duct leakage managed successfully by combination therapy

Feasibility of endoscopic ultrasound‐guided hepaticogastrostomy using a novel long balloon catheter

DEN Open, Volume 5, Issue 1, April 2025.
Abstract Objectives Recently, a novel long balloon catheter for tract dilation in endoscopic ultrasound‐guided hepaticogastrostomy (EUS‐HGS) was developed. The balloon measures 6 cm in length, which enables one‐step tract dilation of the gastric wall, liver parenchyma, and bile duct wall, contributing to shorter procedure times and reduced bile leakage.

Recurrent biliary dissemination of colon cancer liver metastasis: a case report

Journal of Medical Case Reports, 2018
Background Most colorectal cancer liver metastases form nodules within the hepatic parenchyma, and hepatectomy is the only radical treatment for synchronous metastases. There is concern about intrabiliary tumor growth which may affect the surgical margin,
