Anatomical Description of Anterior Parametrium: AProbable Answer to Pelvic Recurrence Following Radical Hysterectomy.

Abstract

A prospective analysis of a retrospective data of patients with cervix carcinoma treated by minimal invasive surgery at high-volume gynecology oncology center analyzing that minimal access surgery is an acceptable treatment modality in cervix carcinoma. The study included 423 patients who underwent laparoscopic/robotic radical hysterectomy after pre-operative evaluation after taking their consent and obtaining ethical approval from the IRB. Post-operatively, patients were followed up at regular intervals for clinical examination and ultrasonography for a median range of 36months. A PET scan was done only if there was any suspicious finding on clinical examination or ultrasonography. Patients with parametrial involvement, positive vaginal margins, and nodal involvement were treated with chemotherapy/radiotherapy. Four hundred twenty-three patients of cervix carcinoma were treated with minimal access surgery. Average duration of surgeries was 92min. Median range of duration of post-operative follow-up was 36months. None of the patients had positive resection margins indicating adequate parametrectomy with complete oncological clearance. On post-operative follow-up, only 2 patients had vaginal recurrence which is comparable to that observed in open surgery and no pelvic recurrence. With the understanding of the anatomical landmarks of the anterior parametrium and development of skills for adequate oncological clearance, minimal access surgery should be the preferred surgical modality in carcinoma of the cervix.
