Summary
Low pressure pneumoperitoneum in laparoscopic cholecystectomy significantly reduces postoperative pain, analgesic needs, and hospital stay. While dissection may be more challenging, it offers considerable benefits for patients undergoing gallbladder surgery.
Area of Science:
- Minimally invasive surgery
- Surgical oncology
- Abdominal surgery
Background:
- Elevated intra-abdominal pressure during laparoscopy impacts organ systems and causes postoperative pain.
- The degree of intra-abdominal pressure correlates with functional changes and pain levels.
- Laparoscopic cholecystectomy can be performed using low-pressure pneumoperitoneum, though it may limit surgical space.
Purpose of the Study:
- To compare the effects of low-pressure (8 mm Hg) versus high-pressure (12 mm Hg) pneumoperitoneum during laparoscopic cholecystectomy.
- To evaluate the impact of different intra-abdominal pressures on patient outcomes, including pain, pulmonary function, and hospital stay.
Main Methods:
- A prospective, randomized, double-blind study involving 26 patients undergoing elective laparoscopic cholecystectomy.
- Patients were assigned to either low-pressure or high-pressure pneumoperitoneum groups.
- Preoperative and postoperative assessments included echocardiography, pulmonary function tests, lower limb Doppler, and arterial blood gas analysis. Pain was assessed using a visual analog scale.
Main Results:
- Low-pressure pneumoperitoneum was associated with significantly lower intraoperative pO2 levels, reduced postoperative pain, decreased analgesic requirements, better pulmonary function, and shorter hospital stays.
- No significant differences were observed in surgery duration or complication rates between the groups.
- Surgeons reported increased technical difficulties with low-pressure pneumoperitoneum, although this was not statistically significant.
Conclusions:
- Low-pressure laparoscopic cholecystectomy is a safe and effective option for uncomplicated gallstone disease in experienced hands.
- Despite potential dissection challenges, low-pressure pneumoperitoneum offers significant advantages in postoperative pain management, analgesic use, pulmonary function preservation, and reduced hospital stay.
