- Abstract
Objective: To determine if video grading using Objective Structured Assessment of Technical Skills (OSATS) could estimate the risk of postoperative bile leak (BL) after robotic pancreatoduodenectomy (RPD) and to identify a learning curve effect., Summary Background Data: The hepaticojejunostomy (HJ) bile leak rate after RPD is rather high with 10% and may be improved by structured training and skills. Robotic HJ therefore requires confirmation of adequate performance. Grading of surgical performance during HJ could be used in competency-based surgical training., Methods: Post-hoc analysis of patients included the Dutch LAELAPS-3 RPD training program in 6 centers. Technical performance during robotic HJ was graded by two blinded graders using OSATS (attainable scores 6-30). Primary outcome was grade B/C bile leak according to the ISGLS. Logistic regression determined the performance cut-off and CUSUM analysis identified the learning curve., Results: Videos from robotic HJ in 259 patients were included with a 6.9% rate of grade B/C bile leak (n=18/259). The median OSATS for the HJ was 25.0 [22-27], with an OSATS score>21 associated with a reduced risk of BL. The rate of BL was 5.1% in patients for OSATS>21 and 12.5% for OSATS ≤21, amounting to a relative reduction of 59.2% and an absolute reduction of 7.4% (8/64 vs. 10/195, OR 0.378, P =0.013). These findings remained similar when only including grade C BL: OR 0.076, P =0.004. On multivariable analysis for grade B/C BL, the only significant predictive factor was OSATS>21: OR 0.273, P =0.025. Stabilization of the CUSUM learning curve for grade B/C BL was reached at 19 RPD procedures, and after 44 procedures the learning curve showed a continuous downward trend. The rate of grade B/C BL was significantly lower beyond 19 RPD: 5.6% versus 8.6% (8/143 vs. 10/116, OR 0.710, P =0.040)., Conclusions: The risk of postoperative BL after RPD is strongly associated with surgical performance during robotic HJ as objectified using OSATS. This approach can be used for rapid assessment of the learning curve and competency-based surgical training, aiming for a safe implementation RPD., Competing Interests: The authors report no conflicts of interest., (Copyright © 2025 The Author(s).
