Treatment of Polidocanol Sclerotherapy in Persistent Lymphatic Drainage After Radical Surgery for Endometrial cancer: A Case Report and Literature Review

Persistent lymphatic drainage and the subsequent formation of lymphatic retention cysts are common complications following radical surgery for gynaecological malignancies. Clinically asymptomatic lymphocysts do not necessitate treatment, whereas symptomatic lymphocysts should be managed through interventional or surgical approaches. However, there is currently no definitive therapeutic method for symptomatic lymphocysts, presenting a persistent challenge in clinical management. Polidocanol sclerotherapy has been utilized in the treatment of various conditions, yet there is a paucity of literature regarding its application in cases of persistent lymphatic drainage. In this study, we present a case involving lymphatic drainage persisting for one month following radical surgery of endometrial cancer. Initially, ultrasound-guided percutaneous tube drainage was employed, but the volume of drainage fluid remained substantial. For the first time, we attempted injection of polidocanol into the cavity of the lymphatic retention cyst. Fortunately, the cyst exhibited significant reduction in size and did not recur subsequently. Our findings suggest a novel therapeutic strategy for the management of symptomatic lymphocysts, and it appears to be a safe and effective approach.
