Reduced postoperative morbidity after elective laparoscopic cholecystectomy: stratified matched case-control study

Area of Science:

• Surgical innovation
• Minimally invasive surgery
• Gastrointestinal surgery

Background:

• Open cholecystectomy (OC) has been the standard treatment for symptomatic cholelithiasis.
• Laparoscopic cholecystectomy (LC) emerged as a less invasive alternative.
• Concerns existed regarding the safety and learning curve associated with LC.

Purpose of the Study:

• To compare the safety of LC versus OC regarding postoperative complications.
• To assess the impact of the learning curve on LC complication rates.
• To establish LC as the current gold standard for cholelithiasis treatment.

Main Methods:

• A matched case-control study design was employed.
• 200 patients undergoing LC (Group A) were matched with two groups of 200 LC patients from different learning curve stages (Groups B and C).
• Complication rates were compared between LC groups and 200 retrospectively matched OC patients.

Main Results:

• The overall complication rate for OC was 16.0%, significantly higher than the 5.5% for LC (p < 0.003).
• LC demonstrated significantly lower rates of Grade I complications, particularly in female patients, those under 70, with low ASA risk, and without surgical difficulties.
• Complication rates in LC significantly decreased with increasing surgeon experience (P < 0.01).

Conclusions:

• Laparoscopic cholecystectomy (LC) is the preferred treatment for symptomatic cholelithiasis.
• LC offers superior safety compared to open cholecystectomy (OC).
• LC is replacing OC as the benchmark for evaluating new surgical therapies.
