Micro-laparoscopic cholecystectomy (micro-LC) with smaller incisions reduced early postoperative pain. However, a high conversion rate to standard laparoscopic cholecystectomy (LC) indicates a need for instrument development.

Area of Science:

  • Minimally Invasive Surgery
  • Surgical Oncology
  • Gastrointestinal Surgery

Background:

  • Laparoscopic cholecystectomy (LC) traditionally uses 10-mm and 5-mm trocars.
  • The impact of smaller port incisions on postoperative pain remains understudied.

Purpose of the Study:

  • To evaluate the effect of smaller port incisions on pain after laparoscopic cholecystectomy.
  • To compare micro-laparoscopic cholecystectomy (micro-LC) with standard LC regarding postoperative pain.

Main Methods:

  • A double-blind, controlled study randomized patients to LC or micro-LC (three 2-mm, one 10-mm trocar).
  • All patients received multimodal analgesia, including local anesthetics, NSAIDs, and paracetamol.
  • Pain was assessed preoperatively, during the first 3 hours postoperatively, and daily for a week.

Main Results:

  • The study was halted due to a 38% conversion rate from micro-LC to LC.
  • In the first 3 hours postoperatively, pain increased significantly in the LC group (n=13) compared to preoperative levels (p<0.01).
  • No significant pain increase was observed in the micro-LC group (n=8) during the same period.

Conclusions:

  • Micro-LC, combined with multimodal analgesia, effectively reduced early postoperative pain.
  • The high conversion rate necessitates further technical development of micro-LC instruments for routine use.
