Robotic Single-Site Tubal Reanastomosis: The Robotic Factor

Abstract Study Objective To investigate the advantages of using robotic assistance in tubal reanastomosis surgery. Design A narrated instructional video. Setting University Hospital, Baylor College of Medicine, Houston, Texas (Canadian Task Force Classification III). Patient A 33-year-old woman, G2P2003, who regretted her prior tubal ligation; she continued to request for a tubal reversal with a desire to conceive in the near future. A single-site approach was decided on when she expressed concern for the cosmetic aftermath of multiport surgery. Interventions Robotic single-site tubal reanastomosis. Measurements and Main Results We performed robotic single-site tubal reanastomosis on the patient. We used the energy instruments of the monopolar hook and the bipolar slotted grasper. Entry was performed in the umbilicus, after which an abdominal survey was conducted to determine and locate the blocked fallopian tubes. A cold scissor, to avoid additional damage to the tubes, was used to resect the portion of the right blocked tube, and a neonatal feeding tube was inserted though both sections of the tube to ensure proper alignment during the repair. Additionally, a figure of eight suture was placed in the mesosalpinx to reduce the amount of tension during the tubal reanastomosis. We used 4 interrupted 5-0 PDS sutures, with 2 wristed needle drivers, to establish and precisely align the 2 sections of tube, first in the mucosal layer and then in the serosal layer, to achieve proper retention. Upon successful chromopertubation with methylene blue dye, the process was repeated on the left side. A successful tubal reanastomosis was completed and chromopertubation clearly demonstrated that the tubes were patent. Total operation time was approximately 100 minutes, resulting in a successful surgery. Estimated blood loss was only 20mL. At 2 months after surgery a fluoroscopic hysterosalpingogram was conducted to verify the patency of the tubes. We concluded that both tubes were patent. Conclusions The single-site robotic approach provides a potent and valuable method for tubal reanastomosis, rendering difficult surgical techniques more accessible.
