Main findings

• Postoperative lower limb cellulitis and infected pelvic cavity lymphocysts did not significantly induce lower limb lymphoedema (LLL).
• A higher BMI was associated with the development of LLL. As the amount of adipose tissue increases in the lower extremity, lymphatic vessels may become dysfunctional, thereby reducing proximal lymphatic flow.
• Patients who underwent pelvic lymphadenectomy (PLA) + para-aortic lymphadenectomy (PALA) have a higher risk of LLL.
• Recent studies revealed the dissection of circumflex iliac lymph nodes (CILs) to be an important risk factor.
• Significant positive correlation between postoperative radiation therapy and LLL.
• Positive correlation between lymphocyst formation and the development of LLL.
