Study Objective To study operative time and cost of robotic assisted laparoscopic tubal anastomosis beyond the learning curve. Secondary objective was to assess pregnancy rate. Design Retrospective Cohort Study. Setting University-affiliated hospital. Patients or Participants All patients who underwent robotic assisted laparoscopic tubal anastomosis from April 2013 to December 2018, performed by a single surgeon at a university-affiliated hospital. Interventions Robotic assisted laparoscopic tubal anastomosis surgery. Measurements and Main Results 109 patients were identified who underwent robotic tubal reversal. Retrospective analysis of EMR was performed. Phone survey was conducted. Operative times were evaluated for 106 cases. Age ranged from 27 to 46 (median 36 ± 4.7), BMI ranged from 18 to 47 (median 29 ± 5.8). Previous ligations included excisional (63%), cautery (13%), and mechanical obstruction (24%). 60% of patients had previous laparotomy. Mean operative time decreased with experience. In 2013, the average operative time was 140.7 ± 27.0 minutes. Average operative time in 2018 was 60.0 ± 9.1 minutes. Downward trend in operative time was highly significant (p The average cost of the surgery was $7,153.46 ± $1,484.41. Direct cost was $4798.25. Follow up information regarding pregnancy outcome was available in 59 patients. Mean follow up time was 37.5 months. 36 patients conceived spontaneously and 23 had not conceived (61%). 75% of patients under 37 became pregnant (n=24), whereas the pregnancy rate was 44% and 45% in the age groups 37-39 (n=7) and >40 years (n=5) respectively. Conclusion There is significant improvement in operative time for robotic assisted tubal anastomosis over time. The operative time of robotic assisted tubal anastomosis beyond the learning curve compares favorably, and may even surpass that of the laparoscopic approach, in our experience. Additionally, this is a cost-effective procedure in our institution when compared to laparoscopic approach. |
