Abstract: Objective To compare the postoperative recovery of patients receiving robotic laparoscopic insulinoma enucleation before and after implementing enhanced recovery after surgery (ERAS) protocol. Methods Anesthetic data of patients who received robotic laparoscopic insulinoma enucleation from January 2013 to March 2016 in Peking Union Medical College Hospital were collected and analyzed. All patients were be divided into routine group and ERAS group. Results The study enrolled 68 patients, whose obesity rate was 69.1%. The intraoperative fluid volume of ERAS group was lower than that of the routine group (P＜0.05), while the difference of urine output was not significant. The maximum peak airway pressure of ERAS group was also lower than that in the routine group(P＜0.05). The postoperative hospital stay length of ERAS group was shorter (P＜0.05). The postoperative complications were uncommon in the ERAS group. Conclusions ERAS protocol can shorten the hospital stay length of patients receiving robotic laparoscopic insulinoma enuleation and postoperative complications are likely to be reduced.
