Early-stage small-bowel adenocarcinoma: a review of local endoscopic therapy.

Early adenocarcinomas in the small intestine are a rare entity. Most adenocarcinomas in the small intestine are diagnosed at a more advanced stage. After surgical resection, only 3 - 10 % are found in stage T1 and 0 - 3 % in stage Tis (high-grade intraepithelial neoplasia), resulting in an overall 3 - 13 % rate of early-stage small-intestinal adenocarcinomas. The diagnosis of early small-intestinal carcinoma by endoscopy is still very rare, although it will probably improve with the development of new endoscopic techniques. At present there have been only two studies and a few case reports on the treatment of early duodenal carcinoma by endoscopic resection. No major complications such as m…

Extraction of Entrapped Capsules from the Small Bowel by Means of Push-and-Pull Enteroscopy with the Double-Balloon Technique

The new technique of push-and-pull enteroscopy using the double-balloon technique (double-balloon enteroscopy) makes it possible to remove swallowed foreign bodies causing intestinal obstruction deep in the small bowel without the need for surgical laparotomy. This report describes two cases of enteroscopic removal of entrapped capsules. In one patient with acute recurrent intestinal bleeding and recurrent abdominal pain, Crohn's disease had been suspected on capsule endoscopy. The second patient, with known Crohn's disease, was suffering from abdominal pain and underwent capsule endoscopy for investigation of the small bowel. Prior enteroclysis had not revealed stenoses in either patient. …

Push-and-pull enteroscopy using a single-balloon technique for difficult colonoscopy.

Background and study aims Several factors predict difficult or incomplete colonoscopy with a standard colonoscope, including female gender, low body mass index, extensive diverticulosis, and prior pelvic surgery. Patients and methods A push-and-pull enteroscopy device and a single-balloon technique was used in 14 patients (six men, eight women; mean age 62 +/- 15 years) after failure of ileocolonoscopy or endoscopic therapy using either a standard or a pediatric colonoscope. The original ileocolonoscopy had been performed to investigate colon polyps (n = 6), an obscure inflammatory process in the ileocecal region (n = 6), or iron deficiency anemia with a positive fecal occult stool test (n …
