Routine single-incision laparoscopic common bile duct exploration with concomitant cholecystectomy for elderly patients: a 6-year retrospective comparative study

Background While single-incision laparoscopic cholecystectomy (SILC) has gained more popularity in recent years, its application to elderly patients needs further evaluation. Few SILC studies regarded this rapidly growing vulnerable population, and single-incision laparoscopic common bile duct exploration (SILCBDE) was never mentioned. We conducted an observational study of 146 routine SILCBDE to address this issue. Methods One hundred forty-six consecutive patients underwent SILCBDE with concomitant cholecystectomies during a period of 6 years (July 2012–June 2016 and July 2018–July 2020). Forty patients with an age of 65 years or older were the study target. Characteristics and operative outcomes were compared with the remaining 106 younger patients by retrospective chart review. The primary outcomes include complications and mortality, while the secondary outcomes contain intraoperative blood loss, operative time, procedural conversions, postoperative length of hospital stay, and bile duct stone recurrence. Results There was no mortality. The bile duct stone clearance rate was 98.6%. The elderly group had higher American Society of Anesthesiologists (ASA) scores, higher comorbidity rate, higher acute cholangitis rate, lower completion intraoperative cholangiography (IOC) rate, longer operative time, more blood loss, longer postoperative hospital stay ( p
