BACKGROUND: While minimally invasive surgery is the current surgical standard of care for excision of deep endometriosis of the bowel, there is little literature evaluating patient-reported outcome measures following a multidisciplinary, robotic approach. OBJECTIVE: This study aimed to assess the functional outcomes of robotic surgery for patients undergoing resection of deep endometriosis involving the bowel. DESIGN: Retrospective cohort review. SETTINGS: A single academic tertiary institution. PATIENTS: Patients with endometriosis of the bowel undergoing multidisciplinary resection between January 1, 2018, and October 1, 2023. MAIN OUTCOME MEASURES: A survey assessing functional outcomes on a Numeric Rating Scale preoperatively and at multiple points postoperatively. RESULTS: Of 92 eligible patients, 41 completed a preoperative survey and at least one postoperative survey. Among these 41 patients, overall pain improved postoperatively from 5.3 ± 2.7 (Numeric Rating Scale) to a nadir of 1.6 ± 1.9 at 6 months and 2.3 ± 3.0 at 12 months ( p < 0.001). Preoperative pain at ovulation (mean 4.2 Numeric Rating Scale ± 3.7), pre-period pain (4.9 ± 3.5), period pain (5.7 ± 3.6) and post-period pain (3.3 ± 3.3) all decreased to a mean of 1 at 12 months postoperatively ( p < 0.001). The proportion of patients reporting pain impacting work decreased from 88% preoperatively to <40% postoperatively ( p < 0.001). The proportion of patients happy with their bowel function increased from 39% preoperatively to 63.2% at 1 month, 80.0% at 6 months, and 69.2% at 12 months postoperatively ( p = 0.014). LIMITATIONS: Only 31.7% of patients responded to their 12-month survey, tertiary care center, low diversity in patient demographics, retrospective design. CONCLUSION: In this cohort of patients undergoing multi-disciplinary robotic excision for advanced endometriosis involving the bowel, patients reported significantly improved pain and quality of life measures.

Intraureteral indocyanine green augments ureteral identification and avoidance during complex robotic‐assisted colorectal surgery
Abstract Aim Up to 10% of patients who undergo nonurological abdominopelvic operations suffer a ureteral injury. While preoperative ureteral stenting to facilitate identification of the ureter is common, it does not reduce the incidence of intraoperative ureteral injury and is not without risk. As we continue to broaden the application of minimally invasive surgical techniques, a new form of ureteral identification and avoidance that does not rely on tactile feedback is needed. We report our initial experience with intraureteral indocyanine green (ICG) for ureteral identification and avoidance during complex robotic‐assisted colorectal surgery. Method Patients undergoing adjunctive ureteral identification during robotic‐assisted colorectal surgery were prospectively identified. Each patient underwent intraureteral ICG administration using rigid cystoscopy (22 Fr). A 5‐Fr open‐ended ureteral catheter was inserted up to 20 cm and used to inject 5 ml of 2.5 mg/ml ICG as the catheter was withdrawn to the ureteral orifice. Intraureteral ICG was then detected using near‐infrared laser fluorescence technology (Firefly®). Results Successful ICG‐enhanced ureteral identification and avoidance was performed in 15 of 16 (94%) patients undergoing robotic‐assisted colorectal surgery. The median ICG instillation time was 11.5 min (range 4–21 min) and the median operative time with ICG visualization was 489 min (8 h 9 min) [range 268–738 min (4 h 28 min–12 h 18 min)]. No patient experienced intraoperative ureteral injury and there were no adverse sequelae or complications associated with intraureteral ICG administration. Conclusion Intraureteral ICG is a safe and effective method of intraoperative ureteral identification and avoidance during complex robotic‐assisted colorectal surgery. Precise and prolonged ureteral visualization was achieved, allowing for long operative times compatible with complex robotic‐assisted operations.
