Postgraduate year does not influence operating time in laparoscopic cholecystectomy.

Area of Science:

• Surgical Education
• Minimally Invasive Surgery
• General Surgery

Background:

• Surgical resident education may increase operating times and costs at teaching hospitals.
• Junior residents' inexperience might prolong laparoscopic cholecystectomy duration.
• This study investigates resident surgical training efficiency.

Purpose of the Study:

• To test the hypothesis that general surgery residents can safely and efficiently perform laparoscopic cholecystectomy.
• To determine if resident training level impacts operative time for this procedure.
• To analyze the influence of gallbladder pathology on surgical outcomes.

Main Methods:

• Retrospective analysis of 71 laparoscopic cholecystectomies over two years.
• Operating times were recorded and compared among junior residents, senior residents, and staff surgeons.
• Cases were stratified by pathologic acuity of gallbladder findings.

Main Results:

• No significant difference in mean operating times was found between resident groups (P=0.2).
• Pathologic acuity was similarly distributed across all surgeon groups (P=0.8).
• Operating time varied significantly based on the pathologic acuity of the gallbladder (P=0.002).

Conclusions:

• Resident training level does not influence laparoscopic cholecystectomy operating time.
• Pathologic acuity, not resident experience, is a key factor in operative duration.
• Laparoscopic cholecystectomy is a safe and efficient procedure in teaching institutions.
