Biliary-intestinal anastomosis is a routine surgery in general surgery, which belongs to the category of tertiary surgery, the recovery time needs to be analyzed according to the severity of the disease, their own ability to recover, etc. In most cases, the recovery period of biliary-intestinal anastomosis ranges from 2-3 weeks or more than 1 month. Biliary-intestinal anastomosis is to anastomose the common bile duct with the jejunum, so that bile flows into the intestine to avoid jaundice, and it is mostly used for biliary obstruction, with pancreaticoduodenal surgical operation, and malignant tumors in the lower end of the common bile duct, and so on. If the patient is young and in good health, and there is no serious infection and obstruction after the operation, the recovery period is usually about 2~3 weeks after the operation. If the patient is older and has poorer recovery ability, coupled with a large area of surgical trauma, and if abdominal infection occurs at this time, the recovery period will generally take more than one month. During the recovery period of bile-intestinal anastomosis, it is necessary to pay attention to a light diet, avoid strenuous exercise, pay attention to rest, and go to the hospital for regular review.
