Timing of robotic hysterectomy after cervical excisional procedure

Abstract

IntroductionWhile traditional teaching has been to wait 6 weeks between cervical excisional procedure and hysterectomy, studies have produced conflicting evidence, with data supporting a delay of anywhere between 48 hours to 6 weeks depending on surgical approach. Our study sought to evaluate if the time between cervical excisional procedure and robotic hysterectomy impacts peri-operative complication rates.MethodsA retrospective cohort of patients who underwent robotic hysterectomy from August 2006 to December 2013 for cervical dysplasia or International Federation of Gynecology and Obstetrics (FIGO) 2009 stage IA1–B1 cervical cancer at a single tertiary care center was performed. Patients were categorized into three groups: early surgical intervention (<6 weeks from excisional procedure), delayed surgical intervention (≥6 weeks from excisional procedure), and no excisional procedure. Secondary analysis was performed by hysterectomy type (simple vs radical). Peri-operative outcomes and complications were compared. Statistical analysis included Chi-square, Fisher’s exact test, and Wilcoxon rank sum test.ResultsA total of 160 patients were identified. Of these, 32 (20.0%) had early surgical intervention, 52 (32.5%) had delayed surgical intervention, and 76 (47.5%) had no excisional procedure. There was no difference between groups in complication rates, including average estimated blood loss (82 vs 55 vs 71 mL; p=0.07), urologic injury (0% in all groups; p=1.0), anemia (3% vs 0% vs 1%; p=0.47), infection (0% vs 2% vs 3%; p=1.0), vaginal cuff separation (0% in all groups; p=1.0), or venous thromboembolism (0% vs 0% vs 1%; p=1.0). Additionally, there were no differences in length of stay (p=0.18) or 30-day readmission rates (p=1.0). Finally, there were no significant differences in peri-operative outcomes when stratified by radical versus simple hysterectomy.DiscussionWaiting 6 weeks between cervical excisional procedure and robotic hysterectomy does not impact peri-operative complication rates. This suggests that the time from excisional procedure should not factor into surgical planning for those who undergo robotic hysterectomy.
