A 68-year-old Japanese woman presented with a solitary pedunculated polyp in the duodenum. Endoscopic ultrasonography showed multiple cystic structures in the polyp. The polyp was successfully resected by endoscopic snare polypectomy and pathologically diagnosed as Brunner's gland hamartoma. Because hamartomatous components were not identified in the stalk of the polyp, we speculate that the st...

Trichobezoars are rare, composed of hair and more common in female pediatric patients with psychiatric disorders. Open surgical extraction is the most common removal method. Only two endoscopic removals after fragmentation have been reported in the English literature. We report herein a third case of a trichobezoar that was successfully retrieved after endoscopic fragmentation with snare polype...

Duodenal lipomas are extremely rare benign tumors. 90% arise from the submucosa and is usually localized in the second portion. They are usually asymptomatic and are detected incidentally during endoscopy or surgery. Appearance of symptoms are related to lesion size, those greater than four centimeters frequently may cause intussusception, obstruction or bleeding. A 59- year-old woman presented...

Colorectal cancer is a major cause of morbidity and mortality worldwide. Their prevention based on screening the average risk population (age 50-75, asymptomatic without personal family history) identification high-risk groups. The vast majority arise from premalignant polyps (adenomas, serrated lesions). Endoscopic polypectomy effective in reducing colorectal incidence mortality. adenoma detec...

BACKGROUND Recently, early detection and early treatment of the colorectal cancer have been enabled by the improvement of endoscopic diagnosis and introduction of new techniques. In Japan, although Japan Polyp Study is running, there is no standard strategy concerning the post-polypectomy colonoscopic surveillance yet. Post-polypectomy colonoscopic surveillance is so far entrusted to each insti...

BACKGROUND AND AIMS Capsule endoscopy (CE) can be prevented by difficulties in swallowing the device and/or its gastric retention. In such cases, endoscopic delivery of the capsule to duodenum is very useful. We describe the indications and outcomes of cases in which traditional endoscopic techniques allowed placement of the capsule in duodenum. PATIENTS AND METHODS This is a retrospective, d...

A boy with generalised infantile polyposis syndrome is reported to highlight the difficulties in management. Despite attempts to reduce polyp mass by regular endoscopic polypectomy, daily transfusions of blood products, and a trial of the non-steroidal anti-inflammatory agent sulindac, his condition gradually deteriorated and he died of septicaemia.

BACKGROUND Randomized controlled trials have demonstrated significant reductions in colorectal cancer incidence and mortality associated with polypectomy. However, little is known about whether polypectomy is effective at reducing colorectal cancer risk in routine clinical practice. The aim of this investigation was to quantify colorectal cancer risk following polypectomy in a large prospective...

A 53 year old woman with respiratory failure and stridor caused by a tracheal plasmacytoma was treated by endoscopic loop polypectomy and neodymium YAG laser therapy, followed by local irradiation. Two years later there was no evidence of recurrence of disease.
