Low pressure pneumoperitoneum (LPP) during laparoscopic cholecystectomy does not improve tissue trauma, pain, or recovery. This study found no significant benefits of using 8 mm Hg versus 15 mm Hg insufflation pressure.

Area of Science:

  • Minimally Invasive Surgery
  • Surgical Physiology

Background:

  • Carbon dioxide insufflation in laparoscopy can negatively impact cardiovascular and respiratory functions.
  • Low pressure pneumoperitoneum (LPP) is known to mitigate adverse hemodynamic effects, but its impact on tissue trauma and postoperative recovery is debated.

Purpose of the Study:

  • To compare tissue trauma, postoperative pain, and recovery between laparoscopic cholecystectomy performed at 8 mm Hg (LC8) versus 15 mm Hg (LC15) insufflation pressures.

Main Methods:

  • Forty patients were randomized into two groups: LC8 (n=20) and LC15 (n=20).
  • Patient characteristics were similar between groups.
  • Key outcomes measured included postoperative pain scores, analgesic use, nausea, vomiting, shoulder pain, C-reactive protein, white blood cell count, and duration of surgery.

Main Results:

  • No significant differences were observed in postoperative pain, analgesic consumption, or incidence of nausea, vomiting, and shoulder pain between LC8 and LC15 groups.
  • Postoperative inflammatory markers (C-reactive protein and white blood cell count) showed similar increases in both groups.
  • Surgical duration was comparable, with a median of 23 minutes for LC8 and 25 minutes for LC15.

Conclusions:

  • The study found no advantages in terms of tissue damage, postoperative pain, or recovery when using low pressure pneumoperitoneum (8 mm Hg) compared to standard pressure (15 mm Hg) in laparoscopic cholecystectomy.
  • The findings suggest that LPP does not offer superior outcomes for these specific parameters in this surgical context.
