A case of situs inversus totalis with hemosuccus pancreaticus due to intrapancreatic pseudocyst perforation of the common hepatic artery treated with a vascular stent graft.

Hemosuccus pancreaticus (HP) is characterized by gastrointestinal bleeding from the papilla of Vater via the pancreatic duct. In this report, we describe a case of HP due to arterial perforation in a pancreatic pseudocyst and discuss the computed tomography (CT) findings and efficacy of stent graft placement. A 64-year-old man with a history of heavy alcohol use, situs inversus totalis, and total gastrectomy was hospitalized with hematochezia.

Technical review of endoscopic ultrasound-guided drainage/anastomosis and trans-endosonographically created route procedures for the treatment of pancreatic diseases.

Endoscopic ultrasound (EUS)-guided pancreatic duct drainage includes two procedures: EUS-guided drainage/anastomosis (EUS-D/A) and trans-papillary drainage with EUS-assisted pancreatic rendezvous. EUS-guided pancreatogastrostomy is the most common EUS-D/A procedure and is recommended as a salvage procedure in cases in which endoscopic retrograde cholangiopancreatography fails or is difficult. However, initial EUS-D/A is performed in patients with surgically altered anatomy at our institution.

Dedicated Echoendoscope for Interventional Endoscopic Ultrasound: Comparison with a Conventional Echoendoscope.

: Interventional endoscopic ultrasound (I-EUS) is technically difficult and has risks of severe adverse events due to the scarcity of dedicated endoscopes and tools. A new EUS scope was developed for I-EUS and was modified to increase the puncture range, reduce the blind area, and overcome guidewire difficulties. We evaluated the usefulness and safety of a new EUS scope compared to a conventional EUS scope.

Current Situation and Problems in Diagnosis of Early Chronic Pancreatitis.

Objectives: The Japan Pancreas Society introduced the concept of early chronic pancreatitis (ECP) in 2009, but its epidemiology remains unclear. This study investigated challenges in ECP diagnosis.

Methods: Early chronic pancreatitis was diagnosed in 4 cohorts between April 2019 and November 2021 using the Clinical Diagnostic Criteria for Chronic Pancreatitis 2019.

A pilot study of Spring Stopper Stents: Novel partially covered self-expandable metallic stents with anti-migration properties for EUS-guided hepaticogastrostomy.

Background And Objectives: EUS-guided hepaticogastrostomy (EUS-HGS) is an effective salvage procedure when conventional endoscopic transpapillary biliary drainage is difficult or fails. However, the risk of stent migration into the abdominal cavity has not been resolved completely. In this study, we evaluated a newly developed partially covered self-expandable metallic stent (PC-SEMS) that has a spring-like anchoring function on the gastric side.

Pancreatic Adenocarcinoma With Strong Expression of Interleukin-13 Receptor α2 Shows a Poor Response to Gemcitabine-Based Chemotherapy.

Objectives: Pancreatic ductal adenocarcinoma with strong expression of interleukin-13 receptor α2 (IL-13Rα2) was associated with poor prognosis and gemcitabine resistance in an orthotopic mouse model. We evaluated the influence of IL-13Rα2 expression in the endoscopic ultrasound-fine needle aspiration (EUS-FNA) specimen.

Methods: We included patients with pancreatic ductal adenocarcinoma, as diagnosed by EUS-FNA, who received gemcitabine-based chemotherapy (G-CTX).

A case of groove pancreatitis with duodenal stenosis successfully treated by endoscopic ultrasonography-guided pancreaticogastrostomy.

One of the reasons for groove pancreatitis is caused by the leakage of pancreatic juice into the space between the pancreatic head, descending duodenum, and common bile duct. Endoscopic drainage of Santorini's duct (SD) via the minor papilla is reportedly efficacious but can be difficult due to duodenal stenosis. We report Santorini's duct drainage using endoscopic ultrasonography-guided pancreaticogastrostomy (EUS-PGS) for a case of groove pancreatitis with gastric outlet obstruction.

Measurement of the anchoring force of covered self-expandable and lumen-apposing metal stents for interventional endoscopic ultrasonography.

Objectives: Interventional endoscopic ultrasonography is performed for various situations that require drainage, after which stent migration is the most severe adverse event. Several lumen-apposing metal stents (LAMS) and covered self-expandable metal stents (CSEMS) provide antimigration systems; however, their anchoring ability has not been studied well. Therefore, we measured and compared the anchoring force (ACF) of commercially available LAMS and CSEMS.

Recent Advances in Pancreato-Biliary Endoscopic Intervention: How to Resolve Unmet Needs in Pancreato-Biliary Diseases Endoscopically.

Various procedures are available for pancreato-biliary (PB) endoscopic interventions [...

A case of endoscopic minor duodenal papillectomy after pancreatic stent placement using an endoscopic ultrasonography-guided rendezvous method.

Video 1The duct was cannulated with a modified MTW catheter using the hitch-and-ride method. A duodenal flap of the 5F, 7-cm pancreatic plastic stent was cut with a surgical scalpel and tied to the duodenal edge of the stent with a 0.3-mm silk suture.

Efficacy and Safety of Peroral Pancreatoscopy Through the Fistula Created by Endoscopic Ultrasound-Guided Pancreaticogastrostomy.

Objectives: Endoscopic ultrasound/endosonography-guided pancreaticogastrostomy (EUS-PGS) is a useful alternative when endoscopic retrograde pancreatography is difficult. Recently, many procedures, including peroral pancreatoscopy (POPS), have been performed through the mature fistula (MF) created by EUS-PGS. We evaluate the efficacy and safety of POPS to diagnose and treat pancreatic ductal stricture/pancreato-jejunal anastomotic stricture (PDS/PJAS) through the MF.

Endoscopic Ultrasound-guided Hepaticogastrostomy in a Seven-year-old Girl.

Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is an effective biliary drainage procedure in adult cases with difficult biliary access. However, there have been no reports on this procedure being used in pediatric cases. We successfully performed EUS-HGS in a pediatric case with a surgically altered anatomy.

Relief Effect of Carbon Dioxide Insufflation in Transnasal Endoscopy for Health Checks-A Prospective, Double-Blind, Case-Control Trial.

CO2 insufflation has proven effective in reducing patients’ pain after colonoscopies but has not been examined in esophagogastroduodenoscopies. Therefore, we examined the effect of CO2 insufflation in examinees who underwent transnasal endoscopies without sedation. This study is a single-center, prospective, double-blind, case-control trial conducted between March 2017 and August 2018.
