No-scalpel vasectomy: What is the learning curve?

Area of Science:

• Urology
• Minimally Invasive Surgery
• Surgical Education

Background:

• No-scalpel vasectomy (NSV) is a WHO-recommended minimally invasive technique underutilized in France.
• Understanding the learning curve is crucial for wider adoption and training.

Purpose of the Study:

• To evaluate the learning curve of no-scalpel vasectomy (NSV).
• To compare NSV with the traditional vasectomy technique regarding operative time, complications, and patient satisfaction.

Main Methods:

• Prospective analysis of 398 patients undergoing vasectomy (199 traditional, 199 NSV).
• CUSUM method used to analyze operative time for the first 50 NSVs versus last 50 traditional vasectomies.
• Patient satisfaction assessed using a 5-point Likert scale.

Main Results:

• NSV operative time was shorter (14.6 min) than traditional vasectomy (21.5 min), decreasing to 9.4 min after the 38th procedure.
• The learning curve peak occurred between the 10th and 21st procedures.
• Patient satisfaction was significantly higher with NSV (p=0.002), with similar efficacy (98.4%) and a trend towards fewer complications.

Conclusions:

• NSV offers reduced operative time and high patient satisfaction compared to traditional vasectomy.
• The technique is rapidly learned, with good outcomes even during the learning phase.
• NSV is an efficient method to meet the demand for vasectomies and optimize surgical procedures.
