Hybrid endoscopic submucosal dissection for anal canal fibroma
An 83-year-old bedridden woman was referred for a suspected rectal polyp that frequently protruded from the anus when passing stools. Although the mass would reduce spontaneously, she experienced extreme discomfort, tenesmus, and occasional rectal bleeding. Ambulatory proctoscopy at the surgery department suggested a tumor in the lower rectum or anal canal.Combination of rubber band traction and partial injection for effective under-gel endoscopic mucosal resection of an ileocecal valve lesion
Neoplasms on the ileocecal valve (ICV) extending into the terminal ileum complicate EMR and endoscopic submucosal dissection (ESD), resulting in lower complete-resection rates; this leads to tumor recurrence.1,2 ESD for ICV neoplasms, although feasible and effective, is time-consuming and not yet established as a standard procedure.2Endoscopic unroofing and mucosal resection for a large colonic lipoma with intussusception: an effective hybrid technique
Lipomas account for 4% of benign subepithelial tumors of the GI tract and are found mainly in the colon (65%-75%).1 Colonic lipomas are often found incidentally during colonoscopy and are often asymptomatic and <20 mm in size and therefore do not require routine colonoscopy or treatment.2 However, in rare cases, colonic lipoma may grow to the point of being symptomatic.Effectiveness of endoscopic Doppler probe ultrasonography for identifying the source of colonic diverticular bleeding
Colonic diverticular bleeding (CDB) is the most common cause of acute lower GI bleeding. The diagnosis of CDB is made through detection of the stigmata of recent hemorrhage (SRH).1,2 To increase the rate of SRH identification, bowel preparation, water-jet endoscope, and transparent hood have been recommended.3 Despite the use of these methods, the rate of SRH identification is only 15% to 40%.1 Even if blood or blood clots are present in the diverticulum, these areas are not always the source of bleeding; in some cases, blood from the bleeding diverticulum flows into other areas.
