Abstract

This study aimed to investigate problems and learning curves experienced by a single surgeon performing robotic-assisted rectal surgery （RRS） for the first time. Among 62 consecutive patients who underwent RRS between May 2021 and December 2022, 30 with high anterior resection （HAR） performed by a single surgeon qualified according to the endoscopic surgical skill qualification system were retrospectively reviewed. Operative feasibility and surgical outcomes were evaluated. The cumulative sum （CUSUM） was used to visualize the learning curve of the operation time. No cases were converted to open surgery. The operative time （median, range） was 313 （163-645） min, the amount of blood loss was 5 （5-550） ml, and postoperative complications occurred in 10 （16.1％） of all 62 patients. Among 30 patients with HAR, the surgeon console time for the 10 patients in the early period was 160 （78-271） min, and that in the later period was 118 （86-234） min for 20 （P＝0.03）. The differences in the duration of lymph node dissection and mesorectal transection were significant between the early and later periods （P＜0.01）. No difference in the frequency of postoperative complications was found. RRS is a minimally invasive and safe technique even for an inexperienced surgeon according to the rectal endoscopic educational system. To shorten the learning curve, mastery of the surgical procedure of lymph node dissection and mesorectal dissection is necessary.
