Five and seven dogs underwent C\u2010TDL and EB\u2010TDL, respectively, and 11 dogs were evaluated by preoperative and 7\u2010 to 10\u2010days\u2010postoperative computed tomography\u2010lymphography (CTLG). No clinical symptoms with absent or minimal pleural effusion was defined as clinical improvement. Long\u2010term remission (LTR) was defined as rapid resolution of pleural effusion and no recurrence for more than 1\u2009year.

The LTR rate was significantly higher with EB\u2010TDL (6\/7 [85.7%]) than with C\u2010TDL (1\/5 [20%]). Anesthesia time, operation time, and time until pleural effusion resolution were significantly better with EB\u2010TDL than with C\u2010TDL.
