Surgical treatment of localised pelvic lymphocyst infection after radiotherapy for endometrial cancer

Endometrial cancer is mainly treated clinically by surgery, supplemented by postoperative radiotherapy. Pelvic and abdominal lymph node dissection is usually an important part of surgery, and one of the most common postoperative complications is lymph node cysts. Infection of cysts is very rare in clinical practice and can be cured mainly by anti-infection and puncture drainage. However, in this case, the patient was found to have a pelvic abscess due to radiating pain in the left lower limb, and the infection of the local lymphocyst was found to have formed a pelvic abscess, and laparoscopic open drainage was performed after puncture drainage with no improvement in symptoms. The patient recovered after surgery.
