Background:Video-assisted minilaparotomy surgery (VAMS) is a hybrid of open and laparoscopic surgical techniques, so has advantages of both approaches. Here we examined the learning curve for this procedure.
Methods: We retrospectively evaluated 50 consecutive patients who underwent VAMS donor nephrectomy performed by a single surgeon (Y.E.Y.) between March 2015 and March 2016. The learning curve was evaluated using the cumulative sum (CUSUM) method.
Results: The mean patient age, body mass index, and body surface area were 43.5 years, 23.8 kg/m2, and 1.7 m2, respectively. The mean operation time and warm ischemic time were 160.0 min and 124.4 s. The learning curve of total operation time was best modeled as a second-order polynomial with equation CUSUMOT (min) = -0.3802 [times] case number2 + 20.315 [times] case number – 41.333 (R2=0.7707). The curve included three unique phases: phase 1 (the initial 17 cases), which is the initial learning curve; phase 2 (the middle 23 cases), expert competence, and phase 3 (the subsequent cases), mastery.
Conclusions: The VAMS donor nephrectomy learning curve is shorter than for laparoscopic or robotic hand-assisted donor nephrectomy. Surgeons can become familiar with the procedure and perform it without complications after approximately 17 operations.
