# Low-Dose Radiation Therapy (LDRT) for Lymphatic Obliteration in Persistent Chylous Ascites: A Case Report

## TL;DR

A patient with persistent chylous ascites after cancer surgery was successfully treated with low-dose radiation therapy, offering a new treatment option.

## Contribution

This case report introduces low-dose radiotherapy as a novel treatment for refractory lymphatic fistulas.

## Key findings

- Low-dose radiation therapy resolved persistent lymphatic leakage in a patient with chylous ascites.
- The treatment showed no recurrence after two years of follow-up.
- Radiotherapy may be an effective option for managing refractory lymphatic fistulas.

## Abstract

Chylous ascites is a rare postoperative complication, typically associated with extensive abdominal procedures and caused by inadvertent injury to the retroperitoneal lymphatic vessels. Its management represents a therapeutic challenge, particularly in cases refractory to conventional strategies. We present the case of a patient with persistent lymphatic leakage following retroperitoneal lymphadenectomy for recurrent testicular cancer, who failed multiple standard interventions. Given the refractory nature of the condition, low-dose external beam radiotherapy was administered, resulting in complete resolution with no recurrence at two-year follow-up. This case highlights radiotherapy as a potentially effective therapeutic option for the management of lymphatic fistulas.
