Background: The best palliation for double obstruction (duodenal obstruction with biliary obstruction) remains unclear. We aimed to compare outcomes of duodenal stenting (DuS) with gastrojejunostomy (GJ) and identify factors associated with survival time and time to recurrent biliary obstruction (TRBO).
Methods: Patients who underwent DuS or GJ combined with biliary stenting for double obstruction due to unresectable malignancy were retrospectively enrolled.
Although previously reported as relatively rare, esophageal hematoma can likely develop in patients on anticoagulants or those with underlying hemorrhagic disorders. From April 2018 to December 2018, among 36 patients who received transcatheter mitral valve edge-to-edge repair (TMVr) at our hospital, seven (19.4%), who were suspected of having digestive tract hemorrhage evidenced by blood stains on a probe extracted after transesophageal echocardiography, underwent esophagogastroduodenoscopy.

Few studies have examined the usefulness of Charlson Comorbidity index (CCI) in this disease, which evaluates the patient's general condition by scoring the patient's underlying disease. There have been no studies investigating the efficacy of CCI compared to other risk scores in the management of UGIB requiring endoscopic hemostasis.

Materials And Methods: A total of 19 patients with unresectable pancreatic cancer who underwent endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA) were enrolled and treated with GEM alone.
Postoperative biliary strictures are usually complications of cholecystectomy. Endoscopic plastic stent prosthesis is generally undertaken for treating benign biliary strictures. Recently, fully covered metal stents have been shown to be effective for treating benign distal biliary strictures.

- IgG4-related disease (IgG4-RD) is a newly identified condition that is not fully understood yet.
- A 68-year-old man presented with itchy skin and pneumonia, leading to a CT scan that showed thickening of his gastric wall.
- After surgery, tests revealed high levels of IgG4-positive cells, confirming a diagnosis of IgG4-RD and highlighting the need for more case studies to better understand the disease.
Aim: To elucidate the role of contrast-enhanced endoscopic ultrasonography (CE-EUS) in the diagnosis of branch duct intraductal papillary mucinous neoplasm (BD-IPMN).
Methods: A total of 50 patients diagnosed with BD-IPMN by computed tomography (CT) and endoscopic ultrasonography (EUS) at our institute were included in this study. CE-EUS was performed when mural lesions were detected by EUS.
