Thin barium meal examination of papilla function after endoscopic sphincterotomy / 中华消化内镜杂志

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.
