Objective To present of laparoscopic resection of bulky para-aortic lymph node metastasis discovered during laparoscopic restaging surgery for unexpected ovarian malignancy

Patients A 45-year-old woman with prior laparoscopic bilateral salpingo-oophorecetomy, presented to our department with unexpected ovarian malignancy which was resulted from the high grade serous carcinoma. Preoperative PET CT scan shows enlarged lymph node in aorto-caval area and no abnormal finding in peritoneal cavity and previous operative site.

Interventions We planned to perform laparoscopic restaging surgery to obtain knowledge about the stage. Laparoscopic restaging surgery included peritoneal washing cytology, LAVH, pelvic lymphadenectomy, para-aortic lymphadenectomy, omentectomy, appendectomy, and multiple peritoneal biopsies. We encountered about 6 cm sized Isolated huge para-aortic lymph node metastasis just before the para-aortic lymphadenectomy. Peritoneal incision was made from right common iliac artery to the duodenum. The bulky nodes were encased and severely densely adhered to important aorta and inferior vena cava. We detached peri-nodal tissue from the vessels meticulously not to rupture of metastatic nodal capsule. Resected nodal specimen carried in the endo pouch was extracted though the opened vaginal vault. The final histopathological results showed lymph node metastases of 4 out of 44 para-aortic lymph nodes and the other of resected tissues were tumor-free. The final diagnosis was FIGO stage IIIC of ovarian serous carcinoma. She is receiving chemotherapy at this time and healthy since then.

Conclusions Our experience indicate that laparoscopy is a feasible and safe approach to resection of bulky para-aortic lymph node metastasis during laparoscopic debulking surgery for gynecologic malignancies.
