BACKGROUND: Difficulties in endoscopic operations and therapeutic procedures seem to occur due to the complexity of operating the endoscope dial as well as difficulty in performing synchronized movements with both hands. We developed a prototype robotic-assisted flexible endoscope that can be controlled with a single hand in order to simplify the operation of the endoscope. The aim of this study was to confirm the operability of the robotic-assisted flexible endoscope (RAFE) by performing endoscopic submucosal dissection (ESD)...

BACKGROUND AND AIMS: During endoscopic submucosal dissection (ESD), a clear view is essential for precise dissection of the appropriate submucosal layer. Some advantages have been reported for underwater techniques of endoscopic resection in comparison with the gas insufflation method. We have developed a new ESD method with the creation of a local water-pocket that provides a clear view in the dissection field. Therefore, we aimed to investigate the feasibility and safety of water-pocket ESD (WP-ESD) for superficial gastric neoplasms...

INTRODUCTION: Esophagectomy combined with lymphadenectomy is currently recommended for patients with high-risk early-stage esophageal cancer after endoscopic treatment (i.e. submucosal tumor invasion [sm2-3], presence of lymphovascular invasion and/or poor tumor differentiation) given the high risk of lymph node metastases. Unfortunately, some patients do not have the physiologic capability to endure surgery. For these patients chemoradiotherapy (CRT) following endoscopic treatment could be an alternative...

BACKGROUND AND AIM: A retrospective study was conducted to compare two resection methods, namely, endoscopic resection (ER) procedures (endoscopic submucosal dissection [ESD], endoscopic muscularis dissection [EMD], and endoscopic full-thickness resection [EFTR]) and laparoscopic resections (LR) (laparoscopic endoscopic cooperative surgery [LECS] and laparoscopic wedge resection). METHODS: Seventy-three patients who underwent ER (N = 33: ESD, N = 4; EMD, N = 15; EFTR, N = 14) or LR (N = 39: LECS, N = 16; wedge resection, N = 23) for gastric submucosal tumor (G-SMT) smaller than 50 mm were included in this study...

Various techniques including cold snare polypectomy and endoscopic mucosal resection are used for the removal of small colorectal polyps. Specimens of resected polyps are prepared in pathology laboratories and analyzed to make a pathological diagnosis. However, reports on how different resection methods influence the pathological diagnosis are limited. This article discusses the problems associated with the failure of polyp retrieval and fragmentation of small specimens during collection and the effects of certain parameters on the pathological diagnosis, particularly with regard to surgical margins...

Endoscopic full-thickness resection (EFTR) is a "changing-concept" endoscopic resection technique, which safely allows resecting deep submucosal tumors (SMTs) in the gastrointestinal (GI) wall. It's a highly promising endoscopic procedure that allows full-thickness excision of a small piece of the complete GI wall by using only a flexible endoscope. EFTR is a meeting point between surgery and endoscopy and probably the onset of many prospective combined minimally invasive therapeutic techniques that science will explore...

The NICE classification is widely used around the world as a universal NBI endoscopic classification that is available without magnifying endoscopy. On the other hand, as histopathological criteria of curative endoscopic resection for early colorectal cancers is getting clear in Japan, endoscopists are required to diagnose their invasion depth accurately with magnifying endoscopy and obtain deeper histopathological materials by endoscopic mucosal resection (EMR)/endoscopic submucosal dissection (ESD). Therefore, we need a new classification which provides accurate qualitative and quantitative diagnosis linking to the appropriate treatment strategy including polypectomy, EMR/ESD, and surgery...

A 74-year-old man was referred to our hospital for further investigation of a cystic lesion in the pancreatic body, which had been detected by ultrasonography at a local hospital. He was diagnosed as intraductal papillary mucinous neoplasm(IPMN) and further preoperative examinations were conducted. Upper gastrointestinal endoscopy demonstrated a type 0-II c tumor of the greater curvature in the upper third of the stomach. Endoscopic ultrasonography showed no sign of submucosal invasion. Endoscopic submucosal dissection(ESD)was carried out and pathological examination of a specimen revealed well differentiated adenocarcinoma with submucosal invasion, which fulfilled the indication for additional gastrectomy with lymph node dissection...

When injected, indocyanine green (ICG) immediately combines with lipoproteins to fluoresce. Here, we studied whether ICG fluorescence is effective for endoscopic marking in gastric cancer surgery using a photodynamic eye (PDE) camera and fluorescent endoscope. An ICG solution was endoscopically injected into the submucosal layer of the gastric tumor 3 days before surgery. We observed the lesions using both a PDE camera and a fluorescent endoscope during laparotomy and laparoscopy, respectively;we also observed the fluorescent luminance and fluorescent size of the resected lesions...

Submucosal diathermy of the inferior turbinate (SMDIT) is a generally safe procedure to control inferior turbinate hypertrophy. We present a case of a cerebrospinal fluid (CSF) leak at the craniocervical junction after SMDIT done in another institution. A 27-year-old man presented 3 weeks after undergoing SMDIT with signs and symptoms of meningitis and postnasal rhinorrhea. Nasal endoscopy and imaging revealed a nasopharyngeal CSF fistula at the craniocervical junction. Transnasal endoscopic repair and reconstruction was performed with no recurrence on repeat imaging and clinical follow up...
