Patient: 4 days after minimally invasive surgery for gallstones, the drainage fluid is not decreasing now, what is the reason? Doctor: Hello, your description is too simple to answer, need to add: gallbladder stones or bile duct stones, drainage fluid is bile (golden yellow) or abdominal exudate (yellowish), is it an attack when the surgery, how much drainage flow. Patient: The details are as follows: on May 8, minimally invasive gallstone removal, on May 9, the drainage fluid was seen to be 200 ml, and drugs were used to inhibit glandular secretion, on May 10, it was 250 ml, and on May 20, the amount reached 350 ml, until now it is more than 300 ml, which should be bile. I would like to ask: Is there any way to solve the problem of bile leakage, and is minimally invasive surgery effective? Thank you. Doctor: Hello, according to your description, consider the bile leakage after laparoscopic cholecystectomy, not the drainage fluid of T-tube after bile duct stone. There are two reasons for this: 1, consider the gallbladder bed small bile duct leakage, also known as vagal bile duct leakage; 2, bile duct leakage, the best way is nasobiliary drainage that is through the endoscope to insert the catheter into the bile duct both to clarify the site of leakage, but also through drainage to achieve the purpose of treating bile leakage. Most cases can be cured.
