We developed the self-propelling capsule endoscope (SPCE), a modified capsule endoscope that can be controlled from outside the patient's body and enables real-time observation. We tested retrograde colon capsule endoscopy with the SPCE in a human volunteer. We used the New MiniMermaid System reported previously.(1) The SPCE was created by connecting a dedicated fin made of silicon resin (19 mm long) with a micro-magnet to the PillCam SB2 video capsule (Covidien, Dublin, Ireland).

The advent of electrical medical records brought image filing systems to many hospitals, as well as electrical endoscopic medical records. However, data integration among multiple different venders has not yet been accomplished. We start the Japan Endoscopic Database (JED) Project endorsed by Japan Gastroenterological Endoscopy Society (JGES) from January 2015. The purposes of this project are as follows: 1) developing the world's largest endoscopic database generated from daily use of the reporting system 2) capturing the actual performance of endoscopic practice in Japan; and 3) standardizing the terminology and fundamental items for the registry of clinical studies...

EUS-guided antegrade (EUS-AG) treatment is a treatment option for bile duct stones (BDS) in surgically altered anatomy patients[1, 2] but can be technically demanding due to the limitation of stone extraction devices[3, 4]. Herein, we presented a case of a difficult BDS successfully removed by two-step EUS-AG treatment after enterobiliary fistula maturation.A 73 year-old male with a history of gastrectomy and Roux-en-Y reconstruction for gastric cancer presented with 12-mm BDS on CT scan (Figure1).

Symptomatic epiphrenic diverticula are mostly treated surgically with laparoscopic diverticulectomy, myotomy and anterior fundoplication. However, in case the patient does not agree with surgical therapy or is contraindicated there are limited ways of alternative treatment. We present a case report of a 72-year-old female patient with severe dysphagia, regurgitation, paroxysmal cough, weight loss and malnutrition who was diagnosed with achalasia and large epiphrenic diverticulum. She did not give consent with surgical treatment that was proposed...

REVIEW
Michael X Ma, Michael J Bourke
Endoscopic submucosal dissection (ESD) was first conceptually described almost 30 years ago in Japan and is now widely practiced throughout East Asia. ESD expands the boundaries of endoscopic resection (ER) by allowing en bloc resection of large early neoplastic lesions within the gastrointestinal tract (GIT). This offers advantages over other ER techniques by facilitating definitive histological staging and curative treatment of early cancer in selected cases. Indeed the experience of ESD in Eastern countries is significant, and excellent outcomes from high volume centres are reported...

OBJECTIVES: Symptomatic cervical heterotopic gastric mucosa also addressed as cervical inlet patch (CIP) may present in varying shapes and causes symptoms of laryngopharyngeal reflux (LPR) like globus sensations, hoarseness and chronic cough. Unfortunately, argon plasma coagulation, standard treatment of small symptomatic CIP, is limited in large CIP mainly due to concerns of stricture formation. Therefore, we aimed to investigate radiofrequency ablation (RFA), a novel minimal-invasive ablation method, in the treatment of CIP focusing on large symptomatic patches...

BACKGROUND: Zenker diverticulum is characterized by dysphagia, weight loss and bronchoaspiration [1]. Open surgery has been the cornerstone of treatment, with good response but recurrence up to 35%.[2]. Rigid endoscopic diverticulotomy has similar results, but with conversion to open surgery up to 30%[3]. Flexible endoscopic diverticulotomy is safe, effective and can be performed in an endoscopic setting, but multiple sessions are needed because of uncomplete cut of the septum[4,5]. Z-POEM is a new procedure in which a total septum myotomy throughout a submucosal tunnel can be performed...

OBJECTIVES: One of the challenges during per-oral endoscopic myotomy (POEM) is ensuring the appropriate length of myotomy on the gastric side. To determine the appropriate distal end of the gastric myotomy, we focused on the two penetrating vessels (TPVs) found in the gastric cardia during POEM. In this study, we evaluated whether the TPVs could serve as an accurate indicator of the appropriate distal end of the gastric myotomy. METHODS: All patients who underwent POEM between March and August 2016 were included for this study...

Bile duct stenting remains the clinical mainstay for establishing biliary drainage in malignant or benign strictures with successful and stable deep guidewire passage as the sine qua non. Duodenal loop formation of an effectively inserted guidewire may occur occasionally and threatens the procedural success in day-to-day ERC practice, which may even be more troublesome after cumbersome guidewire passage in the first place. Attempts to rescue wire positioning often fail, since the wire is typically in a dead angle with a tendency to completely slip out of postion no matter how the scope or cannula is navigated...

BACKGROUND: Surveillance colonoscopy has been performed for patients with long-standing ulcerative colitis, who have an increased risk for colorectal cancer. The aim of this study was to determine the incidence of and the risk factors for neoplasia. METHODS: We evaluated 289 ulcerative colitis patients who underwent surveillance colonoscopy between January1979 and December 2014. The cumulative incidence of neoplasia and its risk factors were investigated. The clinical stage and overall survival were compared between the surveillance and non-surveillance groups...

Since 2001, small bowel capsule endoscopy (SBCE) has been widely implemented into clinical practice as a minimal-invasive diagnostic approach for diagnosing small bowel diseases. Currently, SBCE is moreover recognized as the first-line procedure for the diagnostic work-up of obscure gastrointestinal bleeding (OGIB) and for a variety of SB disorders including Crohn's disease, inherited polyposis syndromes, suspected small bowel tumors or refractory celiac disease [1,2]. In addition, capsule endoscopy is used to guide the decision whether device assisted enteroscopy (i...

An 80-year-old male with obstructive jaundice and prior conventional Billroth II gastrectomy was referred for ERCP. The procedure was performed with side-viewing duodenoscope (Olympus TjF-145) and standard sphincterotome. The afferent limb was intubated and papilla approached from below which located both the direction of cannulation and duodenal stump to appear toward 6 o'clock position.

The incidence of Barrett's esophagus (BE) related neoplasia in Western countries has increased in the past several decades, and even in Eastern countries, it appears to be increasing. Endoscopic therapies are the first-line treatment for BE-related neoplasia, however there is still no standardized treatment strategy. Most of the data have been published from Western countries where the ultimate goal of treatment is complete eradication of BE mucosa removing subtle synchronous lesions and preventing metachronous neoplasia...

Many cases of head and neck cancer are detected on the basis of symptoms and therefore are advanced at the time of diagnosis. Such cancers have been treated by invasive surgery and chemoradiotherapy. Recently, innovative technological developments have been made in gastrointestinal endoscopy in Japan, such as image-enhanced magnifying endoscopy, allowing superficial head and neck cancer to be detected.(1,2) Because superficial head and neck cancer previously could not be detected, diagnostic and treatment strategies have not yet been established and have become a new field of diagnosis and therapy...

Laparoscopic and endoscopic cooperative surgery for duodenal tumor is the precise oncologic resection procedure and the closure of the defect (1). Non-exposed Endoscopic Wall-inversion Surgery (NEWS) is a novel minimally invasive technique for gastric submucosal mass (SMT) and early gastric cancer having advantageous precision to determine the resection line with no risk of peritoneal contamination (2-5). We describe the NEWS technique that we applied and performed for a small duodenal SMT. This article is protected by copyright...

Sessile serrated adenomas/polyps (SSA/Ps) have attracted increasing attention since their risk of developing into cancer was clarified [1]. Difficulty in determining their margins causes incomplete resection [2]. Although narrow-band imaging (NBI) and other advanced imaging systems are reportedly useful in evaluating these polyps [3, 4].

A 64-year-old woman underwent colonoscopy for abdominal discomfort and a protruded lesion measuring approximately 10 mm was detected in the descending colon. The tumor was entirely covered by normal-appearing mucosa and was regarded as a submucosal tumor (SMT). A small adenomatous polyp was present beside the SMT (Figure 1). For precise histological assessment of the SMT and therapeutic purpose of the coexisted polyp, we performed complete resection of the lesions by endoscopic submucosal dissection.

BACKGROUND AND AIM: Esophageal endoscopic submucosal dissection (ESD) to resect widespread lesions has increased the incidence of strictures, and some patients develop strictures despite receiving prophylactic locoregional triamcinolone injections. This study evaluated the predictive factors for esophageal stricture formation in patients administered prophylactic triamcinolone injections after ESD. METHODS: This was a retrospective observational study. Of 552 consecutive patients who underwent ESD, those who received prophylactic triamcinolone injections immediately after ESD were enrolled...
