Biliary pancreatitis

BACKGROUNDS/AIMS: We evaluated long-term pancreatic functional outcomes, including pancreatic volumetry after pancreaticoduodenectomy (PD) for peri-ampullary neoplasm. METHODS: We retrospectively reviewed 353 patients with a 12-month follow-up who underwent elective pancreaticoduodenectomies for peri-ampullary neoplasms at a single university hospital between January 2011 and December 2020. Perioperative and postoperative outcomes, long-term pancreatic endocrine functions, and pancreatic volume changes 12 month postoperatively were evaluated...

Exocrine pancreatic carcinomas are uncommon in dogs and cats, and diagnosis with diagnostic imaging can be challenging. This retrospective, multi-institutional, descriptive study was performed to evaluate the CT features of exocrine pancreatic carcinomas. The CT examinations of 18 dogs and 12 cats with exocrine pancreatic carcinomas diagnosed by cytology or histopathology were reviewed. The CT features of exocrine pancreatic carcinomas included a well-defined mass in 28/30 (93%) with contrast enhancement in 27/30 (90%), commonly heterogeneous 22/30 (73%); often with a nonenhancing fluid to soft tissue attenuating center 12/30 (40%)...

BACKGROUND AND AIMS: Increasing evidence support endoscopic ultrasound-guided biliary drainage (EUS-BD) as a potential alternative to endoscopic retrograde cholangiopancreatography-guided biliary drainage (ERCP-BD) in the primary treatment of malignant biliary obstruction (MBO). This systematic review and meta-analysis aimed to compare the efficacy and safety of both techniques as the initial approach for MBO. METHODS: We searched MEDLINE, Embase, and Cochrane databases for randomized controlled trials (RCTs) comparing both techniques and reporting at least one of the outcomes of interest...

BACKGROUND: Social conditions and dietary behaviors have been implicated in the rising burden of gastrointestinal cancers (GIC). The "food environment" reflects influences on a community level relative to food availability, nutritional assistance, and social determinants of health. Using the US Department of Agriculture-Food Environment Atlas (FEA), we sought to characterize the association of food environment on GIC presenting stage and long-term survival. METHODS: Patients diagnosed with GIC between 2013 and 2017 were identified using the SEER database...

BACKGROUND: This study investigated the clinical application of the indocyanine green (ICG) fluorescence navigation technique in bile duct identification during laparoscopic common bile duct exploration (LCBDE) for complex hepatolithiasis. METHODS: Eighty patients with complex hepatolithiasis were admitted to our department between January 2022 and June 2023 and randomly divided into control and observation groups. The control group underwent conventional LCBDE, while the observation group underwent LCBDE guided by ICG fluorescence...

BACKGROUND: Gallstone pancreatitis (GSP) is common in elderly patients and carries worse outcomes. Laparoscopic cholecystectomy (LC) is recommended for prevention of recurrent GSP. In frail populations, an endoscopic retrograde cholangiopancreatography with sphincterotomy (ERCP-s) is an alternative. Management guidelines of GSP in the elderly are lacking. This study aimed to investigate and compare management strategies for GSP in the elderly. MATERIALS AND METHODS: A retrospective comparison of outcome of patients aged ≥65 years with first presentation of GSP treated either with (1) LC only, (2) ERCP-s, (3) ERCP-S followed by LC, or (4) no intervention...

BACKGROUND AND AIM: Rapidly aging societies have become a major issue worldwide including Japan. This study aimed to elucidate relative changes in the characteristics of inpatients in Japan related to this issue. METHODS: A total of 23 835 Japanese inpatients treated from 2010 to 2021 were enrolled (2010-2013, period I; 2014-2017, period II; 2018-2021, period III). Changes in clinical features were retrospectively analyzed based on ICD-10 diagnosis data. RESULTS: The percentage of patients aged over 75 years increased over time (period I, 38...

INTRODUCTION: Experience with endoscopic retrograde cholangiopancreatography (ERCP) in the pediatric population is limited. Few medical centers have experts specifically trained in pediatric therapeutic endoscopy. As a result, patients are generally referred to adult endoscopists with high experience in the procedure. The aim of this study was to characterize the experience of an adult endoscopy unit with ERCP on pediatric patients, with a special focus on very young patients. METHODS: We retrospectively analyzed indications, technical success rate, final clinical diagnosis, and complications of ERCPs in children <18 years at our tertiary referral hospital center between January 1994 and June 2022...

BACKGROUND: For liver volumetry, manual tracing on computed tomography (CT) images is time-consuming and operator dependent. To overcome these disadvantages, several three-dimensional simulation software programs have been developed; however, their efficacy has not fully been evaluated. METHODS: Three physicians performed liver volumetry on preoperative CT images on 30 patients who underwent formal right hepatectomy, using manual tracing volumetry and two simulation software programs, SYNAPSE and syngo...

BACKGROUND: The advances of minimally invasive endoscopy-guided procedures that usually yield limited diagnostic material changed pancreaticobiliary cytopathology into one of the most challenging areas of Cytopathology given the abundance of differential diagnoses to be considered when dealing with limited specimens. SUMMARY: We describes a few challenging, examples of potential pitfalls in pancreatobiliary cytopathology evaluation collected from a busy academic hospital (tertiary) center...

Due to the widespread use of cancer genetic testing in gastrointestinal cancer, the BRCA1/2 genetic mutation has been identified in biliary tract cancer as well as pancreatic cancer. Niraparib is a poly(ADP-ribose) polymerase (PARP) inhibitor, and PARP inhibitors exert their cytotoxicity against cancer cells in the context of homologous recombination deficiency, such as BRCA mutations, via the mechanism of synthetic lethality. The aim of this phase II NIR-B trial is to evaluate the efficacy and safety of niraparib for patients with unresectable advanced or recurrent biliary tract cancer, pancreatic cancer or other gastrointestinal cancers with germline or somatic BRCA1/2 mutations revealed by genetic testing...

The purpose of preoperative biliary drainage (PBD) is to reduce complications during the perioperative period. The extrahepatic bile duct comprises distal and hilar bile ducts and assessing the need for PBD must be considered separately for each duct, as surgical procedures and morbidities vary. The representative disease-causing distal bile duct obstruction is pancreatic cancer. A randomized controlled trial has revealed that PBD carries the risk of recurrent cholangitis and pancreatitis before surgery, thus eliminating the need for PBD when early surgery is feasible...

Hepatectomy is still the major curative treatment for patients with liver malignancies. However, it is still a big challenge to remove the tumors in the central posterior area, especially if their location involves the retrohepatic inferior vena cava and hepatic veins. Ex vivo liver resection and auto-transplantation (ELRA), a hybrid technique of the traditional liver resection and transplantation, has brought new hope to these patients and therefore becomes a valid alternative to liver transplantation. Due to its technical difficulty, ELRA is still concentrated in a few hepatobiliary centers that have experienced surgeons in both liver resection and liver transplantation...

BACKGROUND: Visceral pain induced by pancreatic cancer seriously affects patients' quality of life, and there is no effective treatment, because the mechanism of its neural circuit is unknown. Therefore, the aim of this study is to explore the main neural circuit mechanism regulating visceral pain induced by pancreatic cancer in mice. METHODS: The mouse model of pancreatic cancer visceral pain was established on C57BL/6N mice by pancreatic injection of mPAKPC-luc cells...
