Abstrakt: Open esophagectomy is considered to be the main surgical procedure in the world for esophageal cancer treatment. Implementing a new surgical technique is associated with learning curve morbidity. The objective of this study is to determine the learning curve based on anastomotic leakage (AL) after implementing minimally invasive Ivor Lewis esophagectomy (MI-ILE) in January 2015. All 257 patients who underwent MI-ILE in a single high-volume center between January 2015 and December 2020 were retrospectively included in this study. The learning curve was evaluated using the standard CUSUM analysis with an expected AL rate of 11%. Secondary outcome parameters were postoperative complications, textbook outcome, and lymph node yield divided by the year of operation. Hierarchical binary logistic regression analysis was used to check for potential confounding variables. The CUSUM analysis showed a learning curve of 179 cases. The mean AL rate decreased from 33.3% in 2015 to 9.5% in 2020 (P = 0.007). There was an increase in the mean lymph node yield from 21 in 2018 to 28 in 2019 (P < 0.001) and textbook outcome from 37.3% in 2015 to 66.7% in 2020 (P = 0.005). A newly implemented MI-ILE has a learning curve of 179 patients based on a reference AL rate of 11% using the CUSUM method. Whether future generation surgeons will show similar learning curve numbers, implicating continuous development of different introduction programs of new techniques, will have to be the focus of future research.
