To demonstrate the use of surgical intelligence to routinely and automatically assess the proportion of time spent outside of the patient's body (out-of-body—OOB) in laparoscopic gynecological procedures, as a potential basis for clinical and efficiency-related insights. A retrospective analysis of videos of laparoscopic gynecological procedures. Two operating rooms at the Gynecology Department of a tertiary medical center. All patients who underwent laparoscopic gynecological procedures between January 1, 2021 and December 31, 2022 in those two rooms. A surgical intelligence platform installed in the two rooms routinely captured and analyzed surgical video, using AI to identify and document procedure duration and the amount and percentage of time that the laparoscope was withdrawn from the patient's body per procedure. A total of 634 surgical videos were included in the final dataset. The cumulative time for all procedures was 639 hours, of which 48 hours (7.5%) were OOB segments. Average OOB percentage was 8.7% (SD = 8.7%) for all the procedures and differed significantly between procedure types (p <.001), with unilateral and bilateral salpingo-oophorectomies showing the highest percentages at 15.6% (SD = 13.3%) and 13.3% (SD = 11.3%), respectively. Hysterectomy and myomectomy, which do not require the endoscope to be removed for specimen extraction, showed a lower percentage (mean = 4.2%, SD = 5.2%) than the other procedures (mean = 11.1%, SD = 9.3%; p <.001). Percentages were lower when the operating team included a senior surgeon (mean = 8.4%, standard deviation = 9.2%) than when it did not (mean = 10.1%, standard deviation = 6.9%; p <.001). Surgical intelligence revealed a substantial percentage of OOB segments in laparoscopic gynecological procedures, alongside associations with surgeon seniority and procedure type. Further research is needed to evaluate how laparoscope removal affects postoperative outcomes and operational efficiency in surgery. [ABSTRACT FROM AUTHOR]

Study Objective: To assess the effect of carbon dioxide (CO2) pneumoperitoneum and steep Trendelenburg position on patients' cardiac function and hemodynamics during minimally invasive staging surgery for endometrial cancer.Design: Single-center prospective longitudinal study.Setting: University-affiliated tertiary hospital.Patients: Patients with endometrial cancer undergoing minimally invasive surgery.Interventions: After consent, the patients' hemodynamic parameters were assessed by the Non-Invasive Cardiac System (NI Medical, Petah Tikva, Israel) at 5 time points: before general anesthesia, after induction of general anesthesia, after CO2 insufflation of the peritoneum, after steep Trendelenburg position, and at the end of surgery.Measurements and Main Results: Twenty-three women were recruited. The median age of the patients was 68 years (interquartile range [IQR] 62-75), with a median body mass index of 34.9 kg/m2 (IQR 31.2-39.5) and an American Society of Anesthesiologists score ≥2. The initial median mean arterial pressure was 108 mmHg (IQR 101-113), and the baseline median cardiac output was 7.2 L/min (IQR 5.6-8.7). The median mean arterial pressure significantly decreased by 18% after insufflation (p = .001), again after Trendelenburg position (p = .003), and did not fully recover at the end of surgery in comparison with the preanesthesia baseline (p = .001). The median stroke volume significantly decreased by 17% after insufflation compared with the baseline (p = .01) and then gradually recovered to the baseline levels by the end of surgery. The median cardiac power significantly decreased by 35% after insufflation (0.009), remained low during Trendelenburg position (p = .009), and recovered by the end of surgery to 18% below the baseline levels (p = .035).Conclusion: Significant hemodynamic changes occur during minimally invasive staging surgery for endometrial cancer. CO2 insufflation is accompanied by the most dramatic hemodynamic deterioration during surgery, and this does not get affected much with Trendelenburg. Knowledge of the hemodynamic values of women classified as high risk when using a noninvasive technique during surgery is obtainable and may assist both surgeon and anesthesiologist to ensure a safer procedure.
