description | STUDY OBJECTIVE: To report the application of the double bipolar technique in a patient with 1b1 cervical cancer who wished to preserve her fertility potential. DESIGN: After experiencing 105 cases of laparoscopic and robotic radical trachelectomy with a 5 year survival rate of 98% and the birth of 29 babies from 51 of these patients who attempted pregnancy, we introduced the double bipolar method to overcome technical difficulties of the procedure due to the necessity for precise dissection and reconstruction in the deep pelvis. We will show our operative techniques, such as nerve sparing radical trachelectomy and retroperitoneal lymphadenectomy for early invasive cervical cancer in a bloodless operative field. SETTING: Urban general hospital. PATIENTS OR PARTICIPANTS: Robotic radical trachelectomy using the double bipolar method was performed in three patients with 1b1 cervical cancer. INTERVENTIONS: After Robotic radical trachelectomy using monopolar scissors in 30 cases of stage Ib1 cervical cancer, we considered techniques for a more bloodless operative field. The double bipolar method (DBM) was originated by a robotic gastrointestinal surgeon, Prof Ichiro Uyama. Using robotic Maryland forceps as a cutting device allows for pinpoint accuracy that cannot be found in other instruments. It is important for bladder and ureteral dissection and exposure of vessels. Cuts are made at a very limited point by a lightning strike mechanism, meaning there is minimal thermal spread to adjacent organs. MEASUREMENTS AND MAIN RESULTS: Blood loss was 250ml in the cases presented. In surgeries not using the DBM(n=34), the blood loss ranged from 350ml(100-1200ml). While there is no supporting data, the dissection of the ureter was very smooth. CONCLUSION: A bloodless operative field allows for accurate dissection and can prevent intraoperative injuries. The double bipolar method is able to provide precision cutting and limit thermal spread to adjacent tissue, reducing injury and allowing for a clear operative field. |
