Lymphocele in the left pelvic iliac fossa after ovarian cancer surgery

Ovarian cancer radical surgery may lead to the formation of a left pelvic iliac lymphatic cyst, possibly due to obstructed lymphatic return, peritoneal injury, or peritoneal infection. Targeted treatments are required, with specific analysis as follows:

1. Obstructed Lymphatic Return

Radical surgery for ovarian cancer involves pelvic lymph node dissection. After removal of the lymph nodes, lymphatic drainage can be blocked, leading to local lymphatic vessel dilation and subsequent cyst formation. In severe cases, lower limb edema may occur. Symptoms can be improved by applying warm compresses using a heated towel.

2. Peritoneal Injury

During radical surgery for ovarian cancer, if the peritoneum is injured, inflammation may develop, resulting in pelvic adhesions. This may compromise hemostasis, leading to postoperative pelvic hematoma and cyst formation, thus causing this condition. Treatment may include medications such as levofloxacin capsules or cefixime capsules under a physician's guidance.

3. Peritoneal Infection

During radical surgery for ovarian cancer, patients with low immunity may develop peritoneal infection, which reduces the peritoneum’s absorptive capacity. As a result, fluid secreted by the ovaries may become encapsulated by surrounding peritoneum, forming an encapsulated pelvic cyst and leading to this phenomenon. Anti-infective therapy with medications such as valacyclovir hydrochloride dispersible tablets or ribavirin tablets may be administered under medical supervision.

In addition to the above, intra-abdominal infection can also cause left pelvic iliac lymphatic cysts after radical surgery for ovarian cancer. When this occurs, prompt and active treatment is essential.
