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: Little is known regarding the risk of tumor dissemination when percutaneous biliary drainage is used before surgical resection of perihilar cholangiocarcinoma (PHC). We aimed to compare the incidence of tumor dissemination after preoperative endoscopic nasobiliary drainage (ENBD) with that after percutaneous transhepatic biliary drainage (PTBD) for PHC. METHODS: Data from 208 consecutive patients who underwent PHC resection between 2000 and 2013 were retrospectively analyzed...

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...

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)...

BACKGROUND: Hepatic resection is the only potentially curative treatment for primary liver tumors and hepatic metastases. The most frightening postoperative complication of extensive hepatectomies is liver failure due to insufficient future liver remnant (FLR). The ALPPS technique (Associating Liver Partition and Portal vein Ligation for Staged hepatectomy) effectively increased the resectability of otherwise inoperable liver tumors (primary or secondary malignant liver tumor) by achieving a rapid and an effective hypertrophy of the FLR, which lowers postoperative liver failure risk...

Ever since the first liver transplant in the Republic of Moldova in 2013 we have performed 30 liver transplantations, the first having been performed in collaboration with the surgical team from Romania, led by Professor Irinel Popescu. The serious deficit of available cadaveric organs has forced us to begin with right hemi-liver transplantation from a living donor. In one third of liver transplantations we used right hemi-liver graft from a living donor, and in 2/3 of cases whole liver graft was harvested from brain-dead donors...

Biliary infections are a common cause of emergency department visit, usually of benign evolution but that can sometimes progress rapidly to a life-threatening emergency.The mainstay of treatment of acute cholecystitis is urgent laparoscopic cholecystectomy, performed in 72 hours.Antibiotic treatment is often sufficient for the initial treatment of mild cholangitis. A percutaneous or endoscopic biliary drainage must be done urgently in case of severe presentations or if the patient doesn't respond to conservative treatment...

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...

Liver transplantation is the only effective treatment for end-stage liver disease, but absolute donor shortage remains a limiting factor. Recent advances in tissue engineering focus on generation of native extracellular matrix (ECM) by decellularized complete livers in animal models. Though proof of concept has been reported for human livers, the current study aims to perform whole liver decellularization in a clinically relevant series using controlled machine perfusion. Here we describe a mild non-destructive decellularization protocol, effective in 11 discarded human whole liver grafts to generate constructs that reliably maintain hepatic architecture and ECM components using machine perfusion, while completely removing cellular DNA and RNA...

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...

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...

Mirizzi syndrome, known as extrinsic bile compression syndrome, is a rare complication of cholecystitis and chronic cholelithiasis, secondary to the obliteration of the infundibulum of the gallbladder or cystic duct caused by the impact of one or more calculations in these anatomical structures, which leads to compression of the adjacent bile duct, resulting in partial or complete obstruction of the common hepatic duct, triggering liver dysfunction. Our aim is to identify and describe the current epidemiology, diagnostic methods, and treatment of Mirizzi syndrome...

Surgical resection is the only potentially curative option in the treatment of pancreatic ductal adenocarcinoma. Preoperative radiological imaging allows to rule out the presence of metastases. Three resectability categories are established based on the radiological findings depending on the degree of contact between the tumor and the blood vessels. Histological confirmation of malignancy is only required in cases of borderline or non-resectable tumors, prior to neoadjuvant treatment initiation. Diagnostic laparoscopy is recommended in the presence of large tumors of the body or tail and in borderline tumors to explore the possibility of resection and to apply treatment with curative intent, as well as in those cases with high level of biomarkers to rule out peritoneal involvement...

OBJECTIVE: To assess the influence of biliary drainage to cholangitis on modified Glasgow Prognostic Score (mGPS) in patients with pancreatic cancer. METHODS: mGPS was calculated before and after biliary drainage in 47 consecutive patients with inoperable pancreatic cancer who were receiving chemotherapy. Biliary drainage was indicated for malignant obstructive jaundice that prevented the administration of chemotherapy. To elucidate mGPS values, serum levels of CRP and albumin were measured at the time of diagnosis (before biliary drainage)...

Cholecystectomy is the treatment of choice for acute cholecystitis but the management of high-risk surgical patients is a difficult dilemma. Percutaneous cholecystostomy (PC) could represent a safer and less invasive option. The aim of the study was to assess the outcomes of PC in high-risk patients. This is a retrospective single-center study; data were collected from our hospital electronic record system. From February 2009 to March 2014, there were 753 patients admitted with acute cholecystitis. Of these 39 were considered high risk for surgery and underwent PC during their hospital stay...
