Robotic type II B posterior exenteration for recurrent vaginal cancer.

OBJECTIVE

To demonstrate a surgical video, wherein a robotic-assisted posterior exenteration was performed for management of recurrent vaginal cancer.

METHODS

We present a case of a 55 year-old female with a history of stage II squamous cell vaginal carcinoma. Patient recurred two years after completion of her primary chemoradiation at the posterior upper vagina. Pelvic MRI showed an approximately 4 cm tumoral nodule, without invasion into rectum or to bilateral parametria. PET-CT ruled out any metastatic disease. She was explained of the palliative systemic treatment versus potentially curative pelvic exenteration, as her options. After extensive counseling, she opted for the surgical option. Given her extensive comorbidities, including poorly controlled diabetes, COPD, obesity and heavy smoking, decision was made to attempt the procedure with a robotic approach (Behbehani et al.; Kammar et al. [1,2]). The technical steps of posterior Type IIB exenteration have been detailed in the video with an emphasis on anatomic landmarks by utilizing visual illustrations (Cibula [3]). The surgical margins were deemed to be negative with frozen section evaluation. Intravenous indocyanine green injection confirmed adequate blood supply to the end colostomy site. Patency of bilateral ureters was confirmed at the end of the procedure.

RESULTS

Robotic-assisted Type IIB posterior pelvic exenteration was successfully completed without any intra-operative complications. Patient was discharged home on post-operative day 8. She has been dispositioned to surveillance.

CONCLUSIONS

Robotic approach to highly morbid pelvic exenteration procedures should be considered in selected patients with recurrent gynecologic malignancies, who present without evidence of distant metastatic disease.
