Objective: From the viewpoint of surgery, this study examined the effects of colorectal endoscopic submucosal dissection (ESD) on treatment for Tis carcinoma over the past 10 years since the technique was adopted. Materials and methods: Among the 3,826 colorectal cancer patients treated at Juntendo University within the 20-year period between 1996 and 2015. The total number of colorectal ESD pe...

Although polypectomy by high frequency electric surgery through the use of endoscopy has been widely applied to polypoid lesions in digestive canals, there have been very few reports of the treatment of bronchial lesions with this procedure. Recently, we have been successful in performing polypectomy without any complications using high-frequency electric surgery through a flexible bronchoscope...

Cold snare polypectomy (CSP) should be performed for benign lesions, though an accurate diagnosis is sometimes difficult with only white light observation. Irregular findings by narrow-band imaging (NBI) are useful for differentiating malignant lesions from benign lesions, and cases with this finding are not expected for CSP. We present a diminutive T1 cancer resected by CSP as a reflection cas...

BACKGROUND AND AIMS Submucosal injection is standard practice in endoscopic mucosal resection of gastrointestinal lesions. Several solutions are used. Our aim was to systematically review their efficacy and safety. PATIENTS AND METHODS We performed a systematic review and meta-analysis using a random effects model of randomized controlled trials (RCTs) from MEDLINE. Studies in animal models w...

Background: Colorectal cancer (CRC) is strongly associated with colorectal polyps, which has become the third most common cancer in China. In the present study, we revealed the susceptible population and risk factors of colorectal polyps, and analyzed the expression of Ki-67, p53 and K-ras in the intestinal mucosa of patients with colorectal polyps in order to explore their significance in the ...

Imaging International Colorectal Endoscopic criteria. Also discussed are study data on endoscopic treatment options, including snare polypectomy, endoscopic mucosal resection, and endoscopic submucosal dissection. Our third feature article explores the use of endoscopic ultrasound (EUS). Over the past 20 years, EUS has gone from being considered solely a supplementary diagnostic tool to being a...
