Resection (tumor debulking) of recurrent ovarian, tubal, primary peritoneal, uterine malignancy (intra-abdominal, retroperitoneal tumors), with omentectomy, if performed, with pelvic lymphadenectomy and limited para-aortic lymphadenectomy

Resection or tumor debulking of intra-abdominal or retroperitoneal tumors is a surgical procedure performed on patients with recurrent malignancies originating from the ovaries, fallopian tubes, primary peritoneum, or uterus. The primary goal of this procedure is to surgically remove as much of the tumor as possible, which is particularly important in cases where complete removal of the tumor is not feasible. This approach, known as tumor debulking, aims to reduce the tumor burden, potentially improving the effectiveness of subsequent treatments such as chemotherapy and immunotherapy. The procedure is typically conducted through an abdominal incision, allowing the surgeon to gain direct access to the tumor site, which may involve the uterus, the uterine adnexa (including the ovaries and fallopian tubes), or the peritoneal cavity. During the debulking process, the surgeon may also perform an omentectomy, which involves the removal of the omentum—a fold of peritoneum that extends from the stomach to other abdominal organs. This structure can harbor cancerous cells, making its removal an important part of the procedure. Additionally, pelvic lymphadenectomy is performed, which entails the excision of lymph nodes located within the pelvis, as well as a limited para-aortic lymphadenectomy, where lymph nodes surrounding the lower aorta are also removed. These steps are crucial for staging the cancer and assessing the extent of disease spread, thereby informing further treatment options. Overall, this procedure is a critical component in the management of recurrent gynecological malignancies, aiming to alleviate symptoms and enhance the patient's overall treatment plan.
