Just a decade ago, peroral endoscopic myotomy (POEM) was performed for the first time to treat esophageal achalasia by Inoue and colleagues, most of who are committee members for the development of the Clinical Practice Guidelines for POEM. Three guidelines have been published for esophageal achalasia, including the international Society for Diseases of the Esophagus Guidelines proposed and endorsed the Achalasia Guidelines (I-GOAL).

The clip-and-thread method has been used to assist colorectal ESD. A laterally spreading tumor (LST) with a large polyp was localized in the splenic flexure of colon (Fig. 1 A, B). A method of ESD with the aid of a snare and endoclips (ESD-SE) was used to resect the LST. This article is protected by copyright. All rights reserved.

Endoscopic submucosal dissection (ESD) is widely accepted for early gastric cancer However, technical difficulties still remain in lesions affected by the direction of gravity, which causes pooling of water, blood, and tiny resection fragments. The complications, such as bleeding and perforation, are often caused by low visibility in those lesions. In present study, we described first application of ESD under D-sorbitol solution, which is used as nonelectrolyte irrigation fluid for monopolar transurethral resection, in beagle model...

BACKGROUND: Current imaging modalities are limited in their ability to distinguish pancreatic cancer (PC) from non-neoplastic pancreatic lesions. The diagnostic use of contrast-enhanced endoscopic ultrasonography (CE-EUS) has increased, and its utility has been reported. Recently, contrast-enhanced harmonic EUS (CH-EUS) was reported to facilitate imaging of parenchymal perfusion and microvessels in pancreatobiliary diseases, leading to a high diagnostic accuracy for PC. This meta-analysis aims to investigate the usefulness of CH-EUS with enhancement pattern for PC diagnosis...

Patients with esophageal squamous cell carcinoma (ESCC) require careful endoscopic inspection of the pharynx to ensure the early detection of pharyngeal cancer. However, the visibility of the hypopharynx is poor because of closure of the lumen, and cancers in this area are often detected at an advanced stage. The Valsalva maneuver has been reported as a useful technique for opening the hypopharyngeal space, and thus, we have started to include the procedure using a dedicated mouthpiece (Valsamouth, MD-49700; Sumitomo Bakelite, Tokyo, Japan) as part of the pretreatment endoscopic examination in ESCC patients (Fig...

Japan Endoscopy Database (JED) was launched to collect the actual data of endoscopic practice throughout Japan. A total of 13,783 patients diagnosed as having gastric cancer (GC) endoscopically (mean age; 69.8±10.7, male/female; 10,060/ 3,723) were registered in the JED project at eight Japanese endoscopic centers between January 2015 and March 2017. The data were collected offline by integrating from two endoscopic filing systems. Table 1 shows the Helicobacter pylori (HP) infection status in 10,433 data-available patients, excluding 3,350 missing-data patients...

Endoscopic ultrasonography guided pancreatic duct drainage (EUS-PD) has been reported as an alternative to surgery in cases where trans-papillary access to the main pancreatic duct (MPD) is not feasible. However, this technique has been reported as a challenging procedure in clinical practice. (1-5). A 64-year-old man presented with repeat pancreatitis caused by a post endoscopic sphincterotomy scar and was admitted to our hospital for pancreatic duct drainage.

Zenker's diverticulum (ZD) is a relatively uncommon esophageal pathology with significant morbidity typically presenting in the elderly population. Symptoms often include dysphagia, halitosis, regurgitation, and food retention [1]. Current treatment options include open surgical cricopharyngeal myotomy/diverticulectomy and rigid or flexible endoscopic techniques. Previous reports have shown decreased rates of complications, as well as shorter procedure and hospitalization times with flexible endoscopic repair...

Anastomotic stricture can occasionally cause repeated acute pancreatitis after partial resection of the pancreas such as pancreaticoduodenectomy or duodenum-preserving pancreatic head resection (DPPHR). Endoscopic ultrasonography-guided pancreatic duct drainage with an oblique-viewing echoendoscope has revealed feasibility and availability [1, 2], while that with a forward-viewing echoendoscope (FV-ES) has extremely been limited [3-5]. We herein describe the first case with pancreaticogastrostomy obstruction treated by direct recanalization with FV-ES...

The implementation of population-based organized screening programs for Colorectal Cancer (CRC) screening generated a heavy strain on the limited capacity of endoscopy resources. In several European countries, such programs are based on a biannual invitation of the target population with Immunochemical Faecal Test (FIT), resulting in a 5-7% rate of test positivity at each round. This burden of post-FIT colonoscopy quickly saturated the availability of colonoscopy capacity that were mainly planned over 30 years earlier for clinical - i...

Endoscopic submucosal dissection (ESD) has been widely accepted as an efficient treatment for early gastrointestinal neoplasms. Several devices, including injection needle, endo-knife, and hemostatic forceps, have been used during ESD procedures. An operator requires help from at least one assistant during ESD procedures such as for device manipulation. Therefore, ESD seems to be a costly procedure. Endosaber (Sumitomo Bakelite, Tokyo, Japan) has been recently invented as an endo-knife for ESD, which does not require to be manipulated by an assistant and can inject solution by itself using water-jet function without an injection needle...

OBJECTIVES: Fine needle aspiration (FNA) cytology has been the preferred technique for procuring tissue at endoscopic ultrasound (EUS) procedures for the past 25 years. To overcome some of the limitations of FNA cytology, fine needle biopsy (FNB) has been recently developed to yield histological tissue. Main objective was to compare the diagnostic yield of FNB compared to FNA for both onsite and offsite specimen assessment. METHODS: A retrospective study was conducted at a single tertiary referral center to evaluate the outcomes of FNA and FNB over a 4-year period...

Endoscopic resection (ER) for non-ampullary superficial duodenal tumors is a technically challenging procedure because of patient-specific anatomical differences. Recently, the performance of ER for non-ampullary superficial duodenal tumors has become widely accepted owing to improvements in the ER technique. However, ER performed for duodenal lesions causes more frequent severe complications, such as delayed perforation and bleeding, when compared to ER performed for other digestive-tract pathologies.

A 74-year-old man was referred to our hospital for treatment of a 20 mm-sized esophageal squamous cell carcinoma (SCC). Upper endoscopy revealed that most of the lesion extended into a diverticulum (Fig. 1a, b). Intrapapillary capillary loops (IPCL) pattern implied that the carcinoma did not invade deep submucosa (Fig. 1c)1 . Endoscopic ultrasonography (EUS) depicted the fourth layer of the esophagus wall inside the diverticulum, suggesting a true diverticulum and that endoscopic submucosal dissection (ESD) was technically feasible (Fig...

OBJECTIVES: Colonic spasm can interfere with colonoscopy, but antispasmodic agents can cause complications. This study aimed to assess the inhibitory effect of topical lidocaine compared with a placebo control. METHODS: In five tertiary-care hospitals in Japan, 128 patients requiring endoscopic resection of a colorectal lesion were enrolled and randomly and double-blindly allocated to colonoscopy with topical administration of 2% lidocaine solution 20mL (LID, n = 64) or normal saline 20mL (control, n = 64)...

BACKGROUND AND AIM: Immunohistological evaluations are essential for diagnosing subepithelial tumors (SET). However, endoscopic ultrasound-guided sampling using fine-needle aspiration (FNA) needles is limited in its ability to procure core tissue for immunostaining. Fine-needle biopsy (FNB) needles may mitigate this limitation. The present study aimed to examine the efficacy of FNB needles for procuring samples that enable the diagnosis of SET. METHODS: One hundred sixty patients were included in the study and separated into those whose samples were obtained using FNB needles (FNB group) and those whose samples were procured using FNA needles (FNA group)...
