The patient was a 73-year-old man who had previously received partial gastrectomy with Roux-en-Y reconstruction due to gastric cancer. He presented with a high fever and abdominal pain and was in a shock state due to biliary pancreatitis and acute severe cholangitis (Figure 1). Emergent balloon enteroscopy was considered difficult because the patient's general condition was relatively poor and a lengthy time was required to complete the intervention.

We performed an EUS-TTNB (endoscopic ultrasound through-the-needle biopsy) in a 48-year-old man with an asymptomatic 4 cm pancreatic neck hypodense lesion, with inhomogeneous slight contrast enhancement. On T2-weighted magnetic resonance imaging (MRI), the lesion appeared as a complex cystic lesion with internal septa, with positive contrast enhancement. Endoscopic ultrasound (EUS) showed a septate PCL (pancreatic cystic lesion) with granular internal aspect, lobulated contours, and no visible cystic walls or mural nodules...

In endoscopic submucosal dissection (ESD) of large colorectal lesions, the retrieval of specimens though the anal canal is sometimes challenging. We introduced a simple technique to solve this problem using a forefinger-compression method (FCM). A superficial tumor 80 mm in size showed nearly circumferential infiltration in the rectum (Fig. 1A). This article is protected by copyright. All rights reserved.

BACKGROUND AND AIMS: EUS-guided drainage (EUS-D) has become the standard treatment for peripancreatic fluid collections. Its use in other intrabdominal abscesses has been reported, although there is limited evidence. PATIENTS AND METHODS: We performed a single center retrospective cohort study comparing percutaneous drainage (PCD) and EUS-D of upper abdominal abscesses between January 2012 and June 2017. Pancreatic fluid collections and liver transplant recipients were excluded...

We report the case of a 61-year-old female with a submucosal tumor (SMT) located in the proximal transverse colon, incidentally diagnosed on screening colonoscopy. Contrast-enhanced abdominopelvic computed tomography showed a well-circumscribed hyperenhancing mass with 20 mm, compatible with a gastrointestinal stromal tumor. On repeat colonoscopy (Olympus® ), after submucosal injection of indigo carmine and saline, a semi-circumferential incision was performed using the HookKnife™ (Olympus® ).

OBJECTIVE: Application of artificial intelligence in medicine is now attracting substantial attention. In the field of gastrointestinal endoscopy, computer-aided diagnosis for colonoscopy is the most investigated area, although it is still in the pre-clinical phase. Because colonoscopy is performed by humans, it is inherently an imperfect procedure. Computer-aided diagnosis assistance is expected to improve its quality regarding automated polyp detection and characterization (i.e., predicting the polyp's pathology)...

A man in his eighties underwent surveillance esophagogastroduodenoscopy after curative endoscopic submucosal dissection for early gastric cancer in the lesser curvature of gastric angle. Endoscopy showed atrophic gastritis (the serum antibody of H. pylori was positive) and an 8 mm, whitish slightly depressed lesion at the posterior wall of the gastric antrum (Fig. 1). This lesion, which was identified six years earlier during an endoscopic submucosal dissection, had not changed in size and morphology during this period...

Mesenteric phlebosclerosis (MP) is a rare disease characterized by ischemia of the colon caused by calcification of the peripheral mesenteric veins and thickening of the colonic wall, and is strongly associated with use of Chinese herbal medicine. To our knowledge, there are no reports of polypoid lesions as an endoscopic finding of MP. A 68-year-old man was referred to us because of a positive fecal occult blood test. He had used 15 types of herbal medicine for the previous 5 years. This article is protected by copyright...

Hideyuki Shiomi, Atsuhiro Masuda, Yuzo Kodama
Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is associated with less technical success and more adverse events than other kinds of EUS-guided biliary drainage (EUS-BD) [1,2]. Therefore, EUS-HGS is challenging specially for less experienced operators. The major reasons for technical failure are loss of the endoscopic position, migration of guidewire and failure of needle tract dilatation. This article is protected by copyright.

Reflux esophagitis, corrosive esophagitis, and esophageal ulcers may cause esophageal stricture after healing. The standard treatment is endoscopic balloon dilation (EBD). Radial incision and cutting (RIC) of scar tissue at the narrowed segment is an effective treatment for strictures refractory to EBD [1][2]. This article is protected by copyright.

Pancreas divisum (PD) is a common anatomical variant of the pancreatic duct system. PD causes recurrent acute pancreatitis (RAP). Endoscopic therapy has been shown to be highly effective in reducing pancreatitis due to PD. Therefore, endoscopic therapy is essential in patients with symptomatic PD. However, endoscopic therapy is challenging because the minor papilla has almost no elevation or apparent orifice and the movement or placement of endoscope is unstable.

Endoscopic biliary stenting is a well-established procedure for malignant distal biliary obstruction. A plastic stent (PS) is frequently used because of its low cost and ease of deployment; however, it may occasionally get dislocated. We herein report a case with unique dislocation of PS and describe the deployment of a new PS via the fistula. This article is protected by copyright. All rights reserved.

OBJECTIVES: With the aging population, an increasing number of individuals on antithrombotic agents are diagnosed with large bile duct stones. Studies have shown the effectiveness of endoscopic papillary large balloon dilation (EPLBD) for removal of large bile duct stones. EPLBD without endoscopic sphincterotomy (EST) may reduce the risk of procedure-related bleeding, but the safety of this procedure for users of antithrombotic agents remains unclear. METHODS: In this multicenter retrospective study, we included patients who underwent EPLBD without EST for bile duct stones between March 2008 and December 2017...

Tissue acquisition under endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is important in obtaining a pathological diagnosis in certain malignant and benign diseases. These include well-differentiated adenocarcinomas, autoimmune pancreatitis, and sarcoidosis. Tissue specimens also allow for additional immunohistological evaluation, which is essential in the diagnosis of diseases such as lymphoma, neuroendocrine neoplasms, and gastrointestinal stromal tumors. More recently, tissue specimens have been of great importance in decision-making pertaining to the administration of specific medicines, such as molecular target agents, as well as the use of molecular biological diagnostic approaches...

BACKGROUND AND AIMS: IgG4-related sclerosing cholangitis (IgG4-SC) presents as isolated proximal-type sclerosing cholangitis (i-SC). This study sought to clarify the imaging differences between i-SC and Klatskin tumor. The differences between i-SC and IgG4-SC associated with autoimmune pancreatitis (AIP-SC) were also studied. METHODS: Differentiating factors between i-SC and Klatskin tumor were studied. The serum IgG4 level, CA19-9 level, CT findings, cholangiography findings (symmetrical smooth long stricture extending into upper bile duct [SSLS]), endosonographic features (continuous symmetric mucosal lesion to the hilar part [CSML]), endoscopic biopsy results, treatment, relapse, and survival were also compared between patients with i-SC and those with AIP-SC...

BACKGROUND AND AIMS: The treatment efficiency of walled-off necrosis (WON) using endoscopic ultrasound-guided drainage (EUS-D) with a double pigtail stent (DPS) is limited. Endoscopic necrosectomy is often performed if EUS-D fails. However, endoscopic necrosectomy is associated with significant morbidity and mortality. Thus, we developed transmural naso-cyst continuous irrigation (TNCCI) as an alternative therapeutic option for WON. This study aimed to evaluate the usefulness of TNCCI therapy for WON...

Gastrointestinal defect closure supports earlier healing of artificial ulcers, and may reduce postoperative adverse events, especially delayed bleeding due to recent increasing proportion of antithrombotic drug uptake. While a colonic artificial defect can easily be closed using endoscopic hemoclips, complete gastric closure is more difficult because of the thick walls. Several closure techniques using the endoloop1,2 and the clip-and-line3 have recently been reported. However, in our experience, these procedures seem to induce muscle damage, as the hemoclips face toward the defect during the approximation of the edges of a defect...

Endoscopic submucosal dissection (ESD) is technically challenging due to lack of depth perception. This report investigated effect of 3D endoscope for ESD and translate the technique from bench to clinical. In preclinical porcine experiment, the performance of ESD using 3D endoscope was compared between experienced and novice endoscopist. All ESD were completed without perforation. The median operative time per surface area was significantly lower for experienced endoscopist than that of novice (197.9s/cm2 vs 434...
