Introduction: Laparoscopic pancreaticoduodenectomy (LPD) is a challenging procedure. We investigated the learning curve (LC) for LPD with a multidimensional analysis. Methods: Data of patients undergoing LPD between 2017 and 2021, operated by a single surgeon, were considered. A multidimensional assessment of the LC was performed through Cumulative Sum (CUSUM) and Risk-Adjusted (RA)-CUSUM analysis. Results: 113 patients were selected. Rates of conversion, overall postoperative complication, severe complication and mortality were 4%, 53%, 29% and 4%, respectively. RA-CUSUM analysis showed a LC with three phases: competency (procedures 1–51), proficiency (procedures 52–94), and mastery (after procedure 94). Operative time was lower in both phase two (588.17 vs 541.13 min, p = 0.001) and three (534.72 vs 541.13 min, p = 0.004) with respect to phase one. Severe complication rate was lower in mastery as compared to competency phase (42% vs 6%, p = 0.005). During mastery phase a greater number of lymph nodes was harvested in comparison to proficiency phase. Conclusions: According to our LC analysis, 52 procedures were required to achieve technical competency in LPD. Mastery, which corresponded to a reduction in operative time and surgical failures, was acquired after 94 procedures.
