A learning curve for laparoscopic splenectomy at an academic institution

Area of Science:

• Minimally invasive surgery
• Surgical training
• Gastrointestinal surgery

Background:

• Laparoscopic splenectomy is becoming the standard for benign splenic disorders.
• Surgeon training for laparoscopic splenectomy presents challenges due to infrequent indications.
• This study details experience with 50 laparoscopic splenic procedures, focusing on the learning curve.

Purpose of the Study:

• To evaluate the learning curve and outcomes of laparoscopic splenectomy at an academic institution.
• To assess the feasibility of training surgical residents in laparoscopic splenectomy.
• To analyze the impact of experience on procedure safety and efficiency.

Main Methods:

• Prospective data collection on 50 laparoscopic splenectomies and 5 open splenectomies (April 1993-April 1998).
• Outcomes analyzed include conversion rates, operative time, tolerance of diet, and length of hospital stay.
• Outcomes were correlated with the number of attempted laparoscopic splenectomy cases.

Main Results:

• Laparoscopic splenectomy evolved from requiring two senior surgeons to being performed by supervised residents.
• Success rates improved from 60% to over 95%.
• Operative time decreased from 195 to 97 minutes, and length of stay reduced from 2.5 to 1.5 days, particularly in the latter half of the study.

Conclusions:

• Laparoscopic splenectomy is a safe and effective procedure with reduced hospital stays.
• The procedure can achieve operative times comparable to open splenectomy.
• Laparoscopic splenectomy can be successfully taught to residents after mastering basic and advanced laparoscopic skills.
