This study demonstrates a minimally invasive laparoscopic cholecystectomy using novel 2.5 mm graspers and a 3 mm laparoscope. The technique proved effective in five patients, offering comparable operation times to conventional methods.

Area of Science:

  • Minimally Invasive Surgery
  • Gastrointestinal Surgery
  • Surgical Instrumentation

Background:

  • Conventional laparoscopic cholecystectomy involves standard-sized instruments.
  • There is a continuous need for less invasive surgical techniques.
  • Smaller instruments may reduce surgical trauma and improve patient recovery.

Purpose of the Study:

  • To evaluate the feasibility and outcomes of laparoscopic cholecystectomy using mini-sized surgical instruments.
  • To compare the invasiveness of this new technique with conventional laparoscopic cholecystectomy.

Main Methods:

  • Laparoscopic cholecystectomy was performed on five patients.
  • Utilized a 2.5 mm grasper and retractor set.
  • Employed a new 3 mm mini-laparoscope.

Related Experiment Videos

  • A 10/12 mm trocar was used for initial access and specimen retrieval.
  • Procedures were primarily conducted through a 5 mm working port.

    • Main Results:

    • Successful completion of laparoscopic cholecystectomy in all five patients.
    • Operation times were comparable to conventional laparoscopic cholecystectomy.
    • The procedure appeared to be more minimally invasive than standard techniques.

    Conclusions:

    • Mini-sized instruments (2.5 mm graspers, 3 mm laparoscope) are feasible for laparoscopic cholecystectomy.
    • This approach offers a potentially more minimally invasive alternative.
    • Further research is warranted to confirm long-term benefits.
