TY - JOUR T1 - EXcessive t-tube drainage following cholecystectomy AU - Freeark RJ Y1 - 1969/07/14 N1 - 10.1001/jama.1969.03160150055024 JO - JAMA SP - 269 EP - 269 VL - 209 IS - 2 N2 - To the Editor:—  I would like to comment on the question and answer to the letter regarding excessive t-tube drainage following cholecystectomy (208:541, 1969).The most common cause of t-tube drainage in excess of 1,000 cc/24 hr is reflux of pancreatic or duodenal secretions into the common duct. I have seen this commonly in patients with a "short" arm t-tube that does not enter the duodenum. Obviously, one may have a "tight" sphincter of Oddi with a common channel of bile and pancreatic juice or patulous sphincter with duodenal contents refluxing up the common duct.The diagnosis is easily confirmed by testing the "bile" for the presence of amylase.
