Abstract Background and Aim: Colonic perforation is the serious accidental complication. The aim of this study to analyze clinical presentation management recent iatrogenic perforations during therapeutic colonoscopy. Methods: Consecutive patients referred four academic cancer centers in Japan were retrospectively reviewed using each center's endoscopy database medical records. Data was obtained by means an extensive data collection sheet. Since we evaluated including newly developed...
Although magnifying chromoendoscopy had been a reliable diagnostic tool, narrow-band imaging (NBI) has developed in Japan since 1999 and now replaced the major role of because its convenience simplicity. In this paper, we principally describe efficacy colonoscopy with NBI for detection, histological prediction, estimation depth early colorectal cancer, future prospects. some meta-analyses have concluded that is not superior to white light detection adenomatous polyps screening colonoscopy,...
<b>Background and study aims:</b> The real-time optical diagnosis of colorectal polyps with high confidence predictions can achieve levels accuracy. Increasing the rates improve clinical application in routine practice. primary aim this prospective was to evaluate whether magnifying endoscopy improves narrow-band imaging (NBI) – based for differentiating between neoplastic non-neoplastic lesions according NBI international endoscopic (NICE) classification. <b>Patients methods:</b>...
AIM:To assess the risk of failing to detect diminutive and small colorectal cancers with "resect discard" policy. METHODS:Patients who received colonoscopy polypectomy were recruited in retrospective study.Probable histology polyps was predicted by six colonoscopists use NICE classification.The incidence their endoscopic features assessed. RESULTS:In total, we found 681 cases (1-5 mm) lesions 402 patients 197 (6-9 151 patients.Based on pathology polyps, 105 18 non-neoplastic 557 154...
<b>Background and study aims:</b> Sessile serrated adenoma/polyps (SSA/Ps) are considered precursors of colorectal cancers with microsatellite instability. However, it is still difficult to differentiate SSA/Ps from hyperplastic polyps endoscopically; therefore, the prevalence remains uncertain in clinical practice. This aimed clarify proportion endoscopically diagnosed features (E-HPs). <b>Patients methods:</b> Patients aged ≥ 40 years undergoing colonoscopy for standard indications at our...
Abstract Background and Aim Although sessile serrated adenoma/polyps (SSA/Ps) are considered to be premalignant lesions rapidly progress carcinomas after they develop cytological dysplasia (CD), a treatment strategy for SSA/Ps in Asian countries is still being debated has not yet been established. The present study aimed propose SSA/Ps. Methods Histopathological data of patients, who underwent colonoscopy at our center between January 2011 December 2016, were reviewed. Data patients with ≥ 1...
Sessile serrated lesions (SSLs) have malignant potential for colorectal cancer in the pathway. Selective endoscopic resection of SSLs would reduce medical costs and procedure-related accidents, but accurate differentiation from hyperplastic polyps (HPs) is challenging. To explore differential diagnostic performance magnifying colonoscopy distinguishing HPs, we conducted a multicenter prospective validation study clinical practice.Considering rarity diminutive SSLs, all ≥6 mm that were...
Control of bleeding is crucial in improving the safety endoscopic mucosal resection (EMR), and intragastric acidity has a great impact on hemostasis blood coagulation. Proton pump inhibitors (PPI) are potent suppressors gastric acid; however, PPI need to be continuously administered orally for several days, thus initial effects may insufficient if only immediately after EMR. The aim this study was determine whether preoperative administration prior EMR can elevate acidity, facilitate better...
Abstract Background Endoscopic resection is widely accepted as a local treatment for rectal neuroendocrine tumors sized ≤ 10 mm. However, there no consensus on the best method endoscopic of tumors. As simplified procedure, submucosal with ligation device (ESMR-L) indicates histologically complete rate comparable to that dissection (ESD). We hypothesized ESMR-L than ESD would be preferred Hence, this trial aimed verify whether non-inferior in terms rate. Methods This prospective, open-label,...
Abstract Perivascular epithelioid cell tumor (PEComa) is a rare mesenchymal tumor. Some papers have reported that colonoscopy could be used to treat PEComa with predominantly pedunculated polyp, whereas surgical intervention often required for cases submucosal‐type tumors. These findings suggest the morphology of changes dramatically disease progression. Because rapid progression PEComa, endoscopic treatment remains challenging, and early‐stage not well understood. A 64‐year‐old man...
AIMTo clarify the diagnostic performance of endocytoscopy for differentiation between neoplastic and nonneoplastic colorectal diminutive polyps. METHODS Patients who underwent betweenOctober December 2016 at Sano Hospital were prospectively recruited.When polyps (≤ 5 mm) detected, lesions evaluated by after being stained with 0.05% crystal violet 1% methylene blue.The
To investigate the post-colonoscopy colorectal cancer (PCCRC) rate for high-definition (HD) colonoscopy compared with that standard-definition reported previously.Using medical records at Sano Hospital (SH) and Dokkyo Medical University Koshigaya (DMUKH), we retrospectively obtained data on consecutive patients diagnosed as having CRC between January 2010 December 2015. The definition of PCCRC was diagnosis 7 36 mo after initial had detected no cancer, were divided into a group non-PCCRC...
Objectives Three subcategories of high‐risk flat and depressed lesions (FDLs), laterally spreading tumors non‐granular type (LST‐NG), lesions, large sessile serrated (SSLs), are highly attributable to post‐colonoscopy colorectal cancer (CRC). Efficient organized educational programs on detecting FDLs lacking. We aimed explore whether a web‐based intervention with training FIND clues (fold deformation, intensive stool/mucus attachment, no vessel visibility, demarcated reddish area) may...
The endocytoscope with ultra-high magnification (x 520) allows us to observe the cellular structure of colon epithelium during colonoscopy, known as virtual histopathology. We hypothesized that could directly colorectal histopathological specimens and store them endocyto-pathological images by endoscopists without a microscope, potentially saving burden on histopathologists.To assess feasibility taken an endoscopist adequate materials for diagnosis.Three gastrointestinal pathologists were...
