Background and study aims Biliary stenting of unresectable malignant bile duct obstruction is generally accepted as the standard of care but it can be hampered by tumor ingrowth and stent dysfunction. We aimed to test the feasibility, safety, and biliary patency rate of a new endoscopically applied intraductal radiofrequency ablation (RFA) device. Patients and methods Eighteen patients with inoperable malignant biliary obstruction underwent endoscopic retrograde cholangiopancreatography (ERCP)-directed RFA and stenting...

OPINION STATEMENT: PURPOSE OF REVIEW: To review the recently published literature on biliary and pancreatic stents. RECENT FINDINGS: Covered self-expanding metal stents (SEMS) are increasingly being used in the endoscopic management of benign biliary strictures. Given the costs associated with SEMS, plastic stents are still the most commonly used stents. In this setting, SEMS are preferred over plastic stents for palliation of malignant biliary strictures due to superior patency and have a role in preoperative management of malignant biliary strictures...

BACKGROUND: Chronic obstruction of the biliary system may cause hepatic fibrosis and liver failure. The purpose of this study was to define the incidence of unrecognized liver fibrosis in patients undergoing pancreaticoduodenectomy (PD). METHODS: Retrospective data were collected on patients undergoing PD during a 21-month period. Each patient had a core needle biopsy at the time of surgery by a hepatobiliary surgeon. RESULTS: This study identified 36 consecutive patients who were referred to a tertiary center and underwent pancreatoduodenectomy during a period of 21 months...

PURPOSE: Although pancreatic cancer is a common malignancy, signet ring cell carcinoma of the pancreas is a very rare histologic type with only 6 cases reported so far. We present a patient with primary signet ring cell carcinoma of the pancreas and a good response to neoadjuvant chemotherapy. CASE REPORT: A 67-year-old woman presented at a regional hospital with a 2-week history of painless progressive jaundice. Abdominal computed tomography showed a tumor in the head of the pancreas, 4...

Preoperative biliary drainage (PBD) prior to pancreatoduodenectomy (PD) has gained popularity as bridge management to resolve jaundice, but its role is being challenged as it is thought to increase morbidity. To clarify the current recommendations for PBD prior to PD, we reviewed the literature, including all relevant articles published in English up until December, 2015. There is increasing evidence that PBD causes bile infection, which is related to the morbidity of infectious complications. Results of transhepatic drainage are poorer than those of endoscopic stenting, especially in an oncologic setting, although it is still unclear whether metallic stents are superior to nasobiliary drainage...

Importance: Surgical site infection (SSI) rates are increasingly used as a quality metric. However, risk factors for SSI in pancreatic surgery remain undefined. Objective: To stratify superficial and organ-space SSIs after pancreatectomy and investigate their modifiable risk factors. Design, Setting, and Participants: This retrospective analysis included 201 patients undergoing pancreatic surgery at a university-based tertiary referral center from July 1, 2013, through June 30, 2015, and 10 371 patients from National Surgical Quality Improvement Program-Hepatopancreaticobiliary (NSQIP-HPB) Collaborative sites from January 1, 2014, through December 31, 2015...

BACKGROUND AND STUDY AIMS : Stent insertion at endoscopic retrograde cholangiopancreatography (ERCP) is an established therapy for managing malignant biliary obstruction. Conventional plastic stents with a tubular design are most commonly used despite limited patency. Plastic stents with a winged design may theoretically increase the duration of stent patency. The aim of this study was to compare stent patency of the winged versus conventional plastic stents in patients with malignant biliary obstruction...

PURPOSE: Internal stents used during pancreaticoduodenectomy (PD) are generally spontaneously passed through the rectum by defecation. However, we encountered six patients with internal stents that migrated into the bile duct after PD. We herein report the outcomes of these six patients and the usefulness of double-balloon enteroscopy (DBE) for removal of such stents from the bile duct. METHODS: An internal stent was placed across pancreaticojejunostomy in 416 (68...

BACKGROUND AND OBJECTIVES: Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) represents an option to treat obstructive jaundice when endoscopic retrograde cholangiopancreatography (ERCP) fails. The success rate of this procedure has been shown to be very high. Up to now, plastic and self-expandable metallic stents (SEMSs) have been employed, each of them presenting some limitations. The aims of this study were to evaluate the technical and functional success rates of EUS-HGS using a dedicated biliary SEMS with a half-covered part (Giobor® stent)...

OBJECTIVES: Endoscopic stenting for combined malignant biliary and duodenal obstruction is technically demanding. However, this procedure can be facilitated when there is guidance from previously inserted stent or PTBD tube. This study aimed to evaluate the feasibility and clinical success rate of endoscopic placement of biliary self-expandable metal stent (SEMS) through duodenal SEMS in patients with combined biliary and duodenal obstruction due to inoperable or metastatic periampullary malignancy...

Adequate biliary drainage with endoscopic or percutaneous placement of self-expandable metal stents represents the goal of palliation in patients with inoperable malignant obstruction of the biliary tree. As an adjunct to stenting, various tissue ablation treatments have been proposed with conflicting results. The aim of this study was to test the effect on biliary tissue of a new ablation technique based on Nd:YAG laser light delivery. The study was conducted on ex vivo specimens of 18 healthy farm pigs, using cystic ducts that are the simplest biliary structures to isolate and cannulate ex vivo...

We appreciate the comments of Dr. Koksal and co-workers on our recent article. In brief, we reported on two first patients with benign biliary strictures treated with self-expanding poly-dioxanone biodegradable biliary stents (BDBS) inserted in endoscopic retrograde cholangiography (ERC). The authors underline that BDBS may cause epithelial hyperplasia in the bile duct similarly to oesophageal use. This article is protected by copyright. All rights reserved.

BACKGROUND AND OBJECTIVES: Endoscopic ultrasound-guided biliary drainage (EUS-BD), first reported as an alternative to percutaneous transhepatic BD in failed endoscopic retrograde cholangiography, is sometimes performed as reintervention for transpapillary stent dysfunction such as in patients with new onset gastric outlet obstruction, but direct conversion to EUS-BD can potentially have a risk of leakage of infected bile. The aim of this study is to evaluate the safety and efficacy of conversion to EUS-BD using a temporary endoscopic nasobiliary drainage (ENBD) tube placement as a reintervention for prior BD...

OBJECTIVE: Plastic biliary stents are commonly placed during endoscopic retrograde cholangiopancreatography (ERCP) and should be removed or replaced within 3 months to reduce the risk of stent obstruction. The aim of the study was to identify predictors and outcomes of patients who had delayed plastic biliary stent removal following ERCP. MATERIALS AND METHODS: Consecutive patients who received ERCP with plastic biliary stent placement at Loma Linda University Medical Center (10/2004-6/2013) were identified...

REVIEW
Kosuke Minaga, Masayuki Kitano
Endoscopic ultrasound-guided biliary drainage (EUS-BD) is increasingly used as an alternative in patients with biliary obstruction who fail standard endoscopic retrograde cholangiopancreatography (ERCP). The two major endoscopic approach routes for EUS-BD are the transgastric intrahepatic and transduodenal extrahepatic approaches. Biliary drainage can be achieved by three different methods, transluminal biliary stenting, transpapillary rendezvous technique, and antegrade biliary stenting. The choice of approach route and drainage method depends on individual anatomy, underlying disease, and location of the biliary stricture...

PURPOSE: The goal of this study was to analyze the outcomes of percutaneous transhepatic management of benign biliary disorders in pediatric patients. MATERIALS AND METHODS: This study included 11 pediatric patients who underwent percutaneous transhepatic biliary interventional procedures between September 2007 and December 2016. There were 3 males and 8 females with a mean age of 9.6±5.4 (SD)years (range: 2-17years). Technical details, complications and outcome of the procedures were evaluated...
