Single-incision plus one-port (S+1) laparoscopic choledocholithotomy offers a safe and effective minimally invasive treatment for choledocholithiasis. This approach reduces operative time and hospital stay compared to traditional methods.

Area of Science:

  • Minimally Invasive Surgery
  • Gastrointestinal Surgery
  • Hepatobiliary Surgery

Background:

  • Choledocholithiasis, the presence of gallstones in the common bile duct, requires effective treatment to prevent complications.
  • Traditional multi-port laparoscopic choledocholithotomy with T-tube drainage is a standard procedure but can be associated with T-tube-related complications and longer recovery times.

Purpose of the Study:

  • To evaluate the safety, feasibility, and efficacy of a novel single-incision plus one-port (S+1) laparoscopic choledocholithotomy with primary suture technique.
  • To compare the S+1 approach against traditional multi-port laparoscopic choledocholithotomy with T-tube drainage in terms of perioperative outcomes and patient recovery.

Main Methods:

  • A prospective study comparing patients undergoing S+1 laparoscopic choledocholithotomy with a control group receiving traditional multi-port laparoscopic choledocholithotomy.

  • The S+1 technique involved a transumbilical multi-channel trocar and a subxiphoid auxiliary port, with primary suture closure of the common bile duct (CBD).
  • Perioperative indicators including operative time, blood loss, hospital stay, and complication rates were analyzed.

    • Main Results:

    • No significant differences in intraoperative blood loss or overall complication rates were observed between the S+1 and traditional groups.
    • The S+1 group demonstrated significantly shorter operative times, reduced time to postoperative flatus, and shorter hospital stays.
    • All complications, such as biliary leakage and residual stones, were managed successfully with minimally invasive interventions, avoiding reoperation.

    Conclusions:

    • Single-incision plus one-port (S+1) laparoscopic choledocholithotomy with primary suture is a safe, feasible, and effective minimally invasive treatment for choledocholithiasis.
    • This technique offers advantages over traditional methods, including reduced invasiveness, cosmetic benefits, and accelerated patient recovery, making it a viable option for selected patients.
