Résumé
Carcinoid tumors of the duodenum are infrequent, represent 2.0-3.0% of all gastrointestinal carcinoid tumors in western countries and 14.8% of those in Japan. Small carcinoid tumors of the duodenum are often asymptomatic, discovered endoscopically, Duodenal carcinoid tumors have been treated by surgical resection or endoscopic resection with strip biopsy or polypectomy. We experience a case of carcinoid tumor of duodenum in 49 years woman. Endoscopic examination, 0.7 cm sized polypoid mass with central depression was noted on duodenal bulb area. We present a case of a small duodenal carcinoid treated with strip biopsy technique.

The incidence of colorectal cancer has been increased gradually and it was about 6.9% of all malignancies in Korea. Early diagnosis was recognized as the most important factor influencing the prognosis of colorectal cancer and the incidence of early colorectal cancer was increasing. Thus great change was observed in the treatment of early colorectal cancer, endoscopic therapy as well as curative surgical resection is being accepted. We report a case of effective and safe endoscopic therapy for early rectal cancer in 5S-year-old male patient. He presented with rectal prolapse and bleeding of a year's duration. A large polypoid mass with fine nodular surface and thick, short stalk was seen in the rectum at 4cm above the anal verge during flexible sigmoidoscopy. After the histologic examination of specimen obtained by bite biopsy, CT scan of pelvic cavity and ultrasonogram of abdomen, the tumor was removed safe and completely by 2 sessions of piecemeal polypectomies and strip biopsy. He has been well without symptoms and signs of recurrence of rectal cancer for 20 months.

We evaluated the role of endoscopic laser therapy and strip biopsy in the treatment of gastric flat adenoma. Over a period of three years, l6 adenomas in 13 patients were ablated with laser irradiation, while 10 adenomas in 7 patients were removed with strip biopsy. The size of adenomas, which ranged from 0.5 cm to 3.5 cm in diameter(mean 1.7 cm) showed no significant difference between the two treatment groups. All of the adenomas were successfully treated with either method and no complications occurred such as bleeding or perforation. The overall one-year recurrence rate was 6.2%. The recurrent adenoma was retreated successfully. We conclude that both endoscopic laser therapy and strip biopsy are safe and effective modalities in the treatment of gastric flat adenoma, but strip biopay may be preferred over laser therapy because the former enables us to examine the resected specimen.

Gastric lipomas are rare benign submucosal tumors which can present the diagnostic and therapeutic problems. The preferred treattment is observation or local excision. Since preoperative diagnosis and differentation from malignant tumors can be difficult by use of the conventional diagnostic modalities such as X-ray or endoscopic examination, patients are sometimes subjected to more extensive surgical procedures than warranted. As to the diagnosis of submucosal tumors of the upper digestive tract, a newly developed diagnostic modality of endoscopic ultrasonography(EUS) allows us to visuialize the structures underlying the gastrointestinal wall in a noninvasive maneuver, and can contribute to make differential diagnosis and decision of management. Strip biopsy is an endascopic tissue resection technique which permits resection of both mucosal and submucosal tissue regardless of the morphological type of the lesion, because the submucosal saline injections during the procedures make the flat or depressed lesions to be elevated. Now, we report a 56-yr-old female which had a Yamada type I polypoid gastric submucosal lipoma in the antrum, which could be performed the different diagnosis and successful endoscopic removal by endoscopic ultrasonography and strip biopsy.
