Advanced Training of Gynecologic Surgeons and Incidence of Intraoperative Complications after Total Laparoscopic Hysterectomy: A Retrospective Study of More Than 2000 Cases at a Single Institution

Abstract

Study ObjectiveTo investigate whether surgeon factors including level of training undertaken in laparoscopic surgery, time in specialist practice, and case volume were associated with surgical morbidity for total laparoscopic hysterectomy (TLH). DesignA retrospective cohort study (Canadian Task Force classification II-2). SettingA tertiary care setting in Western Australia. PatientsTwo thousand thirteen patients who underwent TLH for benign or malignant indications. InterventionsWomen undergoing TLH were allocated to 1 of 3 groups of surgeons: general gynecologists, gynecologic endoscopists, and subspecialists. Measurements and Main ResultsAll patients undergoing elective TLH at St John of God Subiaco Hospital, Subiaco, Perth, Western Australia, between January 1, 2011, and December 31, 2016, were included for analysis. Variables recorded included cystotomy, ureteric injury, enterotomy/colostomy, bowel serosa injury, vascular injury, conversion to laparotomy, return to the operating room, hemorrhage, blood transfusion, operating time, length of stay, and postoperative complications to 42 days. The primary outcome was any major intraoperative complication. The incidence of any major intraoperative complication was 1.8% (36/2013 cases). Forty-five patients (2.2%) had a postoperative complication, and 74 (3.7%) patients were readmitted to the hospital after discharge. The incidence of any major intraoperative complication was significantly higher among general gynecologists compared with subspecialists (3.3% vs 1.1%, p = .002). No association was found between time in specialist practice and the incidence of major intraoperative complications (p = .629). A significant association for major intraoperative complications was observed for surgeons who had performed <100 laparoscopic hysterectomies during the study period (p = .032). ConclusionIn this study, despite a higher level of surgical acuity and the performance of additional and more complex procedures, surgical morbidity was lower in patients undergoing TLH by gynecologic surgeons with a higher level of subspecialist training.
