ABSTRACT

<p><b>OBJECTIVE</b>To assess the diagnostic value of double balloon endoscopy (DBE) for obscure gastrointestinal bleeding (OGIB) METHODS: The data of 103 OGIB patients who underwent DBE from January 2007 to September 2010 in the First Affiliated Hospital, Zhejiang University School of Medicine were retrospectively analyzed.</p><p><b>RESULTS</b>DBE was successfully performed in all 103 patients without complications. Of 103 patients, 66(64.1 %) had positive DBE findings and 28 had surgery procedures(27.2 %). Ninety-four patients finally acquired positive diagnosis, including small intestine tumor(31.1 %), angiodysplasia(22.3 %), exulceratio simplex(9.7 %), Crohn's disease(6.8 %), diverticulum(4.9 %), abdominal purpure(4.9 %), etc. Lesions occurred more frequently in proximal small intestine than in distal small intestine (56.3 % Compared with 30.1 %, P<0.001).</p><p><b>CONCLUSION</b>DBE is a safe, effective and reliable procedure for the diagnosis of OGIB.</p>

ABSTRACT

<p><b>OBJECTIVE</b>The diagnoses of patients with duodenal protruding lesions are difficult when using conventional examinations such as computed tomography (CT) and conventional endoscope etc. Thus, we investigated the clinical value of endoscopic ultrasonography (EUS) with miniature ultrasonic probes on the diagnosis and treatment of duodenal protruding lesions.</p><p><b>METHODS</b>Patients with duodenal protruding lesions who were indicated for EUS were examined by EUS with 12 approximately 15 MHz miniature ultrasonic probes and double-cavity electronic endoscope. According to diagnosis of EUS, those patients were indicated for biopsy and treatment received biopsy, endoscopic resection or surgical excision. The postoperative histological results were compared with the preoperative diagnosis of EUS. Those patients without endoscopic resection or surgical excision were periodically followed up with EUS.</p><p><b>RESULTS</b>A total of 169 patients with duodenal protruding lesions were examined by EUS, of which 40 were diagnosed with cysts, 36 with inflammatory protruding or polyp, 25 with Brunner's gland adenoma, 19 with ectopic pancreas, 17 with gastrointestinal stromal tumor, 12 with extrinsic compression, 12 with minor papilla, 6 with lipoma, 1 with adenocarcinoma and 1 with lymphoma. After EUS examinations, 75 patients received biopsy, endoscopic resection or surgical excision respectively. The postoperative histological results of 70 patients were completely consistent with the preoperative diagnosis of EUS, with 93.33% diagnostic accuracy. The results of follow-up with EUS indicated that duodenal cyst, Brunner's gland adenoma, ectopic pancreas, gastrointestinal stromal tumor and lipoma remained unchanged within 1 approximately 3 years. No related complications occurred among all patients that received EUS examinations.</p><p><b>CONCLUSION</b>EUS is an effective and reliable diagnostic method for duodenal protruding lesions.</p>
