ABSTRACT
Objective To assess short term results of papilla functional status after endoscopic sphincterotomy (EST) with thin-barium meal examination.Methods From August, 2001 to December, 2003, eighty-nine patients were included for endoscopic sphincterotomy. Size of EST was (0.5～1.5) cm. Patients were prospectively followed on the short term-period (7 days, 6 months and 1 year) by clinical and thin-barium(100/100 V/W) meal examination which would be observed biliary gas and barium reflux from duodenal papilla.Results The patient number of gas reflux shows: 19 of 89 cases(21.3%) in one week, 5 of 36 cases(13.9%) in six months, 13 of 23 cases (13.0%)in one year; barium reflux with thin-barium meal examination shows: 11 of 89 cases(12.4%) in one week, 3 of 36 cases(8.3%) in six months, 2 of 23 cases(8.7%) in one year. In the size of EST more than 1.1 cm, these were nine patients (47.4%) with gas reflux, and seven patients (36.8%) with barium reflux, and five patients with gas-barium mix reflux. 6 month and 1 year after sphincterotomy, includes EST size 1.2 cm,2 cases and 1.5 cm,3 cases.Conclusion Thin-barium meal examination of papilla function after endoscopic sphincterotomy is an efficient procedure. Incidence rate of gas reflux and thin barium reflux were closely related to the size of EST.
ABSTRACT
Objective To explore the value of barium meal examination in cartilagionous tracheobronchial ectopia of the esophageal wall.Methods 5 cases of cartilaginous tracheobronchial ectopia in the esophageal wall were found by barium meal examination,all 5 cases were confirmed operatively and pathologically.Results All the 5 cases showed stenosis in the lower part of the esophagus,the “pendulum-like” sign below the stenosis was seen in 4 ases . Conclusion The radiologic manifestations of cartilaginous tracheobronchial ectopia in the esophageal wall are characteristic,and the correct diagnosis may be established preoperatively.
ABSTRACT
Objective To analyze the imaging features of gastrointestinal stromal tumor(GIST).Methods Imaging features and differential diagnosis of GIST proved surgically and pathologically in 21 cases were studied retrospectively.Results The lesions occurred in esophagus in 1,stomach in 15,small intestine in 3 and colon in 2.The findings of barium meal examination included flattened or shifed mucosal folds(6/21),filling defect(8/21) and extralumially oppressed sign(2/21).CT showed extralumial or intraluminal mass with homogeneous density in 12 cases,liquid-dense necrosis in 6 cases and calcification within tumor in 2 cases.Remarkable enhancement was noted in all tumors,heterogeneous and homogeneous enhancement were showed in 17 and 3 cases respectively.Conclusion GIST is one of the most common gastrointestinal mesenchymal tumors.CT is an effective and useful modality in the diagnosis of GIST.
