In the past, the presence of gallbladder stones and common bile duct stones at the same time usually required open surgery (cholecystectomy + choledochotomy) to remove the gallbladder, explore the common bile duct, remove the stones and leave a “T” tube in place; with the advancement of medical technology, many hospitals can now perform laparoscopic cholecystectomy and choledochotomy to remove the stones. In some patients, the incision of the common bile duct can be directly sutured to avoid leaving a “T” tube, which shortens the treatment time; in addition, the combination of laparoscopy and duodenoscopy can be used to treat gallbladder stones and common bile duct stones, that is, laparoscopic cholecystectomy and ERCP to remove common bile duct stones. Although there are various methods, clinicians will choose a most suitable method for the relevant treatment according to the conditions of the hospital, the specific conditions of the patient, such as age, size, number and distribution of stones.
