The Patient and Observer Scar Assessment Scale to Evaluate the Cosmetic Outcomes of the Robotic Single-Site Hysterectomy in Endometrial Cancer.

OBJECTIVE: The objective of this study was to evaluate the cosmetic outcome of robotic single-site hysterectomy (RSSH) in early-stage endometrial cancer. METHODS: We prospectively collected patient demographics, operative times, complications, pathologic results, and length of stay on all patients who underwent RSSH for early-stage endometrial cancer. The Patient and Observer Scar Assessment Scale (POSAS) was used for the evaluation of the cosmetic outcome. RESULTS: Forty-five patients were included in our study from January 2012 to October 2015. The median age of patients was 63 years (range, 35-84 years), and the median body mass index was 26.5 kg/m (range, 18-39 kg/m). No laparoscopic/laparotomic conversion was registered. The median docking time, console time, and total operative time were 7 minutes (range, 4-14 minutes), 46 minutes (range, 20-100 minutes), and 90 minutes (range, 45-150 minutes), respectively. The median blood loss was 50 mL (range, 10-150 mL). Nine patients underwent pelvic lymphadenectomy, and the median number of pelvic lymph nodes was 13 (range, 10-32). The median time to discharge was 3 days (range, 2-6 days). No intraoperative complications occurred, whereas we did observe 1 early postoperative complication. The oncological outcome was directly comparable to the literature. Patients reported low pain scores and high satisfaction in terms of postoperative scarring. The POSAS scores confirmed excellent cosmetic outcome of RSSH. CONCLUSION: Robotic single-site hysterectomy provided an efficient option for gynecologic oncologic surgery. The POSAS revealed high objective and patient-evaluated outcome, and patients were highly satisfied with the overall outcome of the appearance of their scars.

Robotic single site versus robotic multiport hysterectomy in early endometrial cancer: a case control study.

OBJECTIVE: To compare surgical outcomes and cost of robotic single-site hysterectomy (RSSH) versus robotic multiport hysterectomy (RMPH) in early stage endometrial cancer. METHODS: This is a retrospective case-control study, comparing perioperative outcomes and costs of RSSH and RMPH in early stage endometrial cancer patients. RSSH were matched 1:2 according to age, body mass index, comorbidity, the International Federation of Gynecology and Obstetric (FIGO) stage, type of radical surgery, histologic type, and grading. Mean hospital cost per discharge was calculated summarizing the cost of daily hospital room charges, operating room, cost of supplies and length of hospital stay. RESULTS: A total of 23 women who underwent RSSH were matched with 46 historic controls treated by RMPH in the same institute, with the same surgical team. No significant differences were found in terms of age, histologic type, stage, and grading. Operative time was similar: 102.5 minutes in RMPH and 110 in RSSH (p=0.889). Blood loss was lower in RSSH than in RMPH (respectively, 50 mL vs. 100 mL, p=0.001). Hospital stay was 3 days in RMPH and 2 days in RSSH (p=0.001). No intraoperative complications occurred in both groups. Early postoperative complications were 2.2% in RMPH and 4.3% in RSSH. Overall cost was higher in RMPH than in RSSH (respectively, $7,772.15 vs. $5,181.06). CONCLUSION: Our retrospective study suggests the safety and feasibility of RSSH for staging early endometrial cancer without major differences from the RMPH in terms of surgical outcomes, but with lower hospital costs. Certainly, further studies are eagerly warranted to confirm our findings.
