Biliary leakage is a challenging complication when managing the bile duct strictures. The etiology of benign strictures of the biliary tree may have different etiologies but iatrogenic is the most common, with relevant increase after introduction of laparoscopic procedures. Interventional radiologist plays a key role, both in diagnosis and treatment of biliary strictures and leakage. We report on a case of a 39-year-old woman affected by abdominal pain and jaundice after laparoscopic cholecystectomy; jaundice was caused by surgical clipping of the common bile duct...

Background and study aims:  Biliary strictures are frequently a challenging clinical scenario and the anatomopathological diagnosis is essential in the therapeutic management, whether for curative or palliative purposes. The acquisition of specimens is necessary since many benign diseases mimic biliopancreatic neoplasms. Endscopic retrograde cholangiopancreatography (ERCP) is the traditionally used method despite the low sensitivity of biliary brush cytology and forceps biopsy. On the other hand, several studies reported good accuracy rates using endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA)...

Background: Obstructive jaundice is one of the most common symptoms which can be caused by both malignant and benign hepato-biliary-pancreatic diseases. The differences and the differential diagnostic roles of the serum CA19-9, total bilirubin (TBIL) and especially, the ratio of CA19-9 to TBIL in these patients have not been well elucidated. This study compared the differences and the differential diagnostic roles of the increase-folds of the serum CA19-9, TBIL and the ratio of increase-folds of CA19-9 to increase-folds of TBIL in 508 cases of malignant (MOJ) and benign (BOJ) obstructive jaundice patients...

This brief report presents the results of 20 adult and pediatric patients treated with the use of biodegradable SX-Ella biliary stents placed by means of a transhepatic approach for the treatment of benign biliary strictures after liver transplantation. Stent insertions were always feasible (100%), and only 1 case of acute pancreatitis was observed (5%). The overall clinical success rate of the procedure, including anastomotic and nonanastomotic strictures, was 75%, and was higher in the anastomotic stricture group (81...

Biodegradable self-expanding stents are an emerging alternative to standard biliary stents as the development of endoscopic insertion devices advances. The aim was to systematically review the existing literature on biodegradable biliary stents. In-vivo studies on the use of biodegradable stents in the biliary duct were systematically reviewed from 1990 to 2017. Despite extensive research on the biocompatibility of stents, the experience so far on their clinical use is limited. A few favorable reports have recently been presented on endoscopically and percutaneously inserted self-expanding biodegradable polydioxanone stents in benign biliary strictures...

BACKGROUND: Benign biliary stricture (BBS) is highly refractory. Currently, there is no effective strategy for prevention of BBS recurrence. The aim of this study is to establish a novel BBS rabbit model and to investigate the efficacy of biliary infusion with anti-proliferative medications for treating BBS. METHOD: A BBS model was established via surgical injury and biliary infection. The biliary infusion tube was inserted into the common bile duct via the stump of cystic duct after cholecystectomy...

Increasing evidence has demonstrated that serum soluble B7-H4 (sB7-H4) is a useful tumour marker for cancer diagnosis and prognosis evaluation. Whether sB7-H4 is expressed in the bile of cholangiocarcinoma (CC) and is related to the progression of CC need to be explored. Bile sB7-H4 was obtained through endoscopic retrograde cholangiopancreatography (ERCP) from 213 patients with biliary strictures and detected was detected by a B7-H4 ELISA kit. Diagnostic value was compared among bile sB7-H4, CA19-9, CA12-5, CEA and ERCP-based cytological/tissue examination...

BACKGROUND & AIMS: EUS-guided hepaticoenterostomy (EUS-HE) is usually reserved for palliation of malignant biliary obstruction after failed endoscopic retrograde cholangiography (ERC) or inaccessible biliary tree in surgically altered anatomy (SAA). We describe outcome of EUS-HE and antegrade therapy for benign biliary disease in patients with SAA. METHODS: Retrospective review of 20 consecutive patients with surgically altered anatomy and benign biliary obstruction who underwent EUS-HE performed by one endoscopist at a tertiary center over a three-year period...

Purpose Stricture formation at the biliary enteric anastomotic site is a common complication due to fibrotic healing. Few therapeutic options are available for biliary-enteric anastomotic site stricture (BES) including new surgical reconstruction or percutaneous transhepatic biliary drainage followed by balloon dilation of BES or stent placement. The purpose of this study is to assess the technical success, complications and reintervention rate of percutaneous transhepatic balloon dilatation (PTBD) of BES after iatrogenic bile duct injuries (BDI)...

BACKGROUND: Pancreatoduodenectomy sometimes causes late benign biliary complications, such as biliary stricture and/or hepaticolithiasis, which require intervention. The risk factors and timing of late biliary complications remain unclear. The purpose of this study was to clarify the incidence, timing of occurrence, and risk factors for late biliary complications after pancreatoduodenectomy. METHODS: A total of 732 patients who underwent pancreatoduodenectomy between 2002 and 2016 were included in this retrospective study...

Background: Paclitaxel (PTX) could inhibit the growth of fibroblasts, which occurs in proliferative cholangitis and leads to biliary stricture. However, its use has been limited due to poor bioavailability and local administration for short time. This study designed and synthesized a new PTX-conjugated chitosan film (N-succinyl-hydroxyethyl chitosan containing PTX [PTX-SHEC]) and evaluated its safety and efficiency using in vivo and in vitro experiments. Methods: The SHEC conjugated with PTX was confirmed by nuclear magnetic resonance (NMR) and Fourier-transform infrared spectroscopy (FT-IR) measurements...

Benign biliary strictures have a broad spectrum of etiologies. There have been no reported cases, however, of a biliary stricture secondary to a migrated suture after laparoscopic distal gastrectomy (LDG). Here, we report one such case. The patient was a 60-year-old man who underwent LDG with Roux-en-Y reconstruction for early gastric cancer. Pathology revealed early cancer (T1N0M0) with a curative resection. Two years after LDG, the patient was found to have elevated hepatobiliary enzymes. After further workup, the new diagnosis was invasive cholangiocarcinoma (T2N0M0), and the patient underwent pancreaticoduodenectomy...
