Hemorrhoids are the most common anorectal complaint, and approximately 10 to 20 percent of patients with symptomatic hemorrhoids require surgery. Symptoms of hemorrhoids, such as painless rectal bleeding, tissue protrusion and mucous discharge, vary. The traditional therapeutic strategies of medicine include surgical, as well as non-surgical, treatment. To alleviate symptoms caused by hemorrhoi...

133 While the safety of endoscopic banding liga-tion is largely undisputed, there is one major risk of this technique: esophageal perforation during insertion of the overtube. Perforation of the esophagus often occurs as a result of inability to relax the pharyngeal muscle by the patient and forceful insertion of the tube by the endoscopist. The development of multiple banding ligators (Speedba...

A 20-year-old woman was admitted with iron deficiency anemia and history of melena. Upper endoscopy demonstrated normal esophagus, stomach and proximal duodenum. At colonoscopy, two bluish pedunculated angiectatic polypoid lesions (1 to 2 cm in diameter) were noted due to blue rubber bleb nevus syndrome (BRBNS). The small intestine was screened for further lesions with the use of capsule endosc...

UNLABELLED THE AIM OF THE STUDY was to evaluate the results of the treatment of internal hemorrhoids and anal mucosal prolapse using elastic band ligation and to compare this method to chosen surgical procedures. MATERIAL AND METHODS The study included 648 patients (363 males and 285 females). 474 patients were treated using an elastic band ligature and 174 patients underwent surgical hemorrh...

In a 45-year-old woman with epigastric discomfort for 1 year, upper gastrointestinal endoscopy and endoscopic ultrasonography (EUS) showed a hypoechoic solid mass originating from the muscularis propria of the posterior wall of the gastric fundus (●" Fig.1). EUS revealed that this 0.8×0.6cm mass was probably a gastrointestinal stromal tumor (GIST) because of its morphological characteristics; t...

This paper presents three selection techniques (called Rubber-lingsweep, Line-string and Coupling-with-pressure) to enhance multi-target acquisition in GUIs and to overcome the drawback of the standard rubber-band box technique, i.e., the limitation of not being able to select an irregular layout of targets. Rubber-line-sweep utilizes a rubber-band line to select targets by “sweeping” them. Lin...

tumor, which is occasionally found during screening colonoscopy. Tumors less than 1 cm in diameter and limited in depth to the submucosal layer can be managed by endoscopic treatment, several types of which have been reported for rectal carcinoid tumor [1,2]. Because carcinoid tumor extends to the submucosal layer, simple endoscopic mucosal resection (EMR) will often leave tumor involvement in ...
