The NCCN Guidelines for Hepatobiliary Cancers focus on the screening, diagnosis, staging, treatment, and management of hepatocellular carcinoma (HCC), gallbladder cancer, cancer bile ducts (intrahepatic extrahepatic cholangiocarcinoma). Due to multiple modalities that can be used treat disease complications arise from comorbid liver dysfunction, a multidisciplinary evaluation is essential determining an optimal treatment strategy. A team should include hepatologists, diagnostic radiologists,...
In 2023, the NCCN Guidelines for Hepatobiliary Cancers were divided into 2 separate guidelines: Hepatocellular Carcinoma and Biliary Tract Cancers. The provide recommendations evaluation comprehensive care of patients with gallbladder cancer, intrahepatic cholangiocarcinoma, extrahepatic cholangiocarcinoma. multidisciplinary panel experts meets at least on an annual basis to review requests from internal external entities as well evaluate new data current emerging therapies. These Insights...
Experience with minimal access, transoral/transmural endoscopic drainage/debridement of walled-off pancreatic necrosis (WOPN) after necrotizing pancreatitis is limited. We sought to determine outcome using this technique.Retrospective analysis.From 1998 2006, 53 patients underwent sterile (27, 51%) and infected (26, 49%) WOPN. Intervention was performed a median 49 days (range, 20-300 days) onset acute pancreatitis. A 3 procedures/patient 1-12) were performed. Twenty-one (40%) required...
Background and study aims: Endoscopic retrograde cholangiopancreatography (ERCP) is an established modality for evaluation treatment of pancreaticobiliary disorders. However, it technically more challenging in patients with post-surgical anatomy. The success rate ERCP prior pancreaticoduodenectomy (Whipple resection) unknown. We assessed the technical safety this patient population. Patients methods: Post who had undergone between January 2002 May 2005 were identified through a computerized...
Endoscopic ultrasound-directed transgastric endoscopic retrograde cholangiopancreatography (ERCP; EDGE) is an alternative to enteroscopy- and laparoscopy-assisted ERCP in patients with Roux-en-Y gastric bypass anatomy. Although short-term results are promising, the long-term outcomes not known. The aims of this study were: (1) determine rates adverse events after EDGE, a focus on persistent gastrogastric or jejunogastric fistula; (2) identify predictors (3) assess closure when fistula...
Abstract Backgrounds Endoscopic ultrasound (EUS)-guided placement of lumen-apposing metal stents (LAMSs) has gained popularity for the treatment pancreatic walled-off necrosis (WON). We compared 20-mm and 15-mm LAMSs symptomatic WON in terms clinical success adverse events. Methods conducted a retrospective, case-matched study 306 adults at 22 tertiary centers from 04/2014 to 10/2018. A total 102 patients with who underwent drainage LAMS (cases) 204 (controls) were matched by age, sex,...
Abstract EUS-guided gallbladder drainage (EUS-GBD) using lumen apposing metal stents (LAMS) has excellent technical and short-term clinical success for acute cholecystitis (AC). The goals of this study were to determine the long-term outcomes adverse events (AEs) EUS-GBD with LAMS. A multicenter, retrospective was conducted at 18 US tertiary care institutions. Inclusion criteria: any AC patient attempted LAMS minimum 30-day post-procedure follow-up. Long-term defined as absence recurrent...
Introduction EUS-guided gall bladder drainage (EUS-GBD) for management of symptomatic gallbladder disease has been shown to be safe and effective in high surgical risk patients with data lacking cirrhosis. We sought study the safety effectiveness EUS-GBD cirrhotic compared non-cirrhotic patients. Methods Retrospective review who underwent at four (3 US 1 Spain) international tertiary care centers. collected baseline variables outcomes being procedural technical success, clinical success...
Same-day performance of esophagogastroduodenoscopy (EGD) and colonoscopy is called bidirectional endoscopy (BDE). BDE commonly performed, but the optimal sequence for which procedure to do first not well established. This study in US investigate BDE. We performed a cohort patients with same-day (2003–2018) at our institution. The two groups were (1) EGD followed by (UL) (2) Colonoscopy (LU). Endpoints included duration, extent reached, sedation, diagnostic yield. 22,905 underwent BDE,...
Endoscopic retrograde cholangiography (ERC) is a well-established modality for diagnostic and therapeutic maneuvers in pancreaticobiliary disorders. However, it technically more challenging patients with postsurgical anatomy like Roux-en-Y anastomoses. Its effectiveness post–orthotopic liver transplantation (OLT) biliary reconstruction has not been reported. We sought to assess the efficacy safety of ERC this patient population. A total 132 OLTs were performed at our institution from June...
When carrying out endoscopic submucosal dissection (ESD), procedural safety increases with greater tissue elevation and efficiency longer-lasting cushion. Fluids specifically developed for ESD in Asia are not commercially available the West, leaving endoscopists to use a variety of injectable fluids off-label. To determine optimal fluid we compared commonly used Western ESD.All phases were carried an ex vivo porcine stomach model. Phase 1 duration cushions produced by various standard...
INTRODUCTION: Differentiating mucinous neoplastic pancreatic cysts (MNPC) from without malignant potential can be challenging. Guidelines recommend using fluid carcinoembryonic antigen (CEA) to differentiate MNPC; however, its sensitivity and specificity vary widely. Intracystic glucose concentration has shown promise in differentiating MNPC, but data are limited frozen specimens cohorts of patients histologic diagnoses. This study aimed compare CEA concentrations MNPC fresh obtained with...
Objective: To evaluate the safety and efficacy of endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) using a lumen-apposing metal stent (LAMS). Background: For patients with acute cholecystitis who are poor surgical candidates, EUS-GBD LAMS is an important treatment alternative to percutaneous drainage. Methods: We conducted regulatory-compliant, prospective multicenter trial at 7 tertiary referral centers in United States America Belgium. Thirty consecutive mild or moderate were...
The prognostic and pathophysiologic significance of the biliary microbiota in pancreaticobiliary malignancies is little understood. Our goal was to find malignancy-related microbiomic fingerprints bile samples taken from patients with benign malignant diseases.Bile specimens were collected consenting during routine endoscopic retrograde cholangiopancreatography. We used PowerViral RNA/DNA Isolation kit extract DNA specimens. Illumina 16S Metagenomic Sequencing Library Preparation guide...
