Objective:
To evaluate the feasibility of robotic microsurgical tubal anastomosis and compare the results and cost effectiveness with the same procedure performed by laparotomy.
Design:
Prospective cohort study.
Setting:
University hospital.
Patient(S):
Patients with a history of bilateral tubal ligation who desired reversal for future fertility.
Intervention(S):
Tubal anastomoses through either a robotic approach or through a laparotomy.
Main Outcome Measure(S):
Operative times, hospitalization, complications, postoperative patency, clinical outcomes, and the cost per live birth.
Result(S):
The mean operative time for robotic anastomoses was statistically significantly greater than open anastomoses (ROBOT 201 minutes; OPEN 155.3 minutes), although hospitalization times were statistically significantly shorter (ROBOT 4 hours; OPEN 34.7 hours). The return to instrumental activities of daily living was accelerated in the patients who had undergone a robotic anastomosis (ROBOT 11.1 days; OPEN 28.1 days). Although this was a small series, the pregnancy rates were comparable between groups (ROBOT 62.5%; OPEN 50%), yet the rate of abnormal pregnancy was higher in the robotic group (ectopic: ROBOT 4, OPEN 1; spontaneous pregnancy loss: ROBOT 2, OPEN 1). The cost per delivery was similar between the groups (ROBOT $92,488.00, OPEN $92,205.90).
Conclusion(S):
Robotically assisted laparoscopic microsurgical tubal anastomosis is feasible and cost effective with results that are comparable with the traditional open approach.
