To explore the safety and feasibility of modified minimally invasive surgery for cholecystolithiasis and choledocholithiasis in elderly patients.

We conducted a retrospective analysis of 100 patients more than 70 years old with cholecystolithiasis and choledocholithiasis performed by modified endoscopic retrograde cholangio-pancreatography (endoscopic sphincterotomy small incision + endoscopic papillary balloon dilation) combined with laparoscopic cholecystectomy from January 2012 to December 2017 in the Traditional Chinese Medicine Hospital of KunShan.

In this group, there was 1 case of papillary bleeding, which was stopped by 1: 10000 adrenalin submucosal injection, and there were 3 cases of pancreatitis, 2 cases of cholangitis, all of which were improved after conservative treatment of internal medicine.No patient was transferred for open surgery and no death occurred. Postoperative hospital stays were 4-10 days, with an average of (5.3±2.8) days.The mean follow-up time was 2-24 months, mean (7.5±5.1) months.No abdominal pain, jaundice or fever occurred. No recurrence of bile duct stones was observed under ultrasonography.

modified ERCP+ EST combined with LC is an effective, safe and reliable minimally invasive treatment for elderly patients with cholecystolithiasis and choledocholithiasis.
