Study ObjectivePatients with symptomatic malignant pleural effusion are usually treated with large-bore chest tube placement and pleurodesis requiring > or = 3 days of hospitalization. We sought to demonstrate the feasibility of ambulatory drainage and sclerosis using a small-bore pigtail catheter in patients with malignant pleural effusions. We reasoned that this approach would improve symptoms and quality of life at a reduced cost.MethodsA 14F pigtail catheter was percutaneously inserted into the pleural space and connected to a closed gravity-drainage bag system. The patients were instructed in the use of the drainage system and discharged to return for sclerosis with 4 g of talc after the drainage was < 100 mL/24 h. Patients were graded for dyspnea and performances status using the Eastern Cooperative Oncology Group score (ECOG) and baseline and transitional dyspnea index score (BDI-TDI) before tube placement and again at 30 days. Radiographic response was graded as total response, partial response, or failure. Telephone follow-up was initiated when the patient could not return for evaluation.ResultsTen ambulatory women, ages 41 to 79 years, were enrolled. The chest tube was left in place from 1 to 10 days, draining a mean of 2,956 mL (1,685 to 6,050 mL). Only two patients were unable to undergo sclerosis owing to catheter dislodgment and minimal drainage. Six reported symptomatic improvement at 30 days confirmed by TDI and ECOG scores in four of six. One with a prior history of a lobectomy was found to have a chylous pleural effusion and experienced a hydropneumothorax, for which sclerosis was unsuccessful. One died in hospital on day 26 after sclerosis despite radiographic resolution. Of the four patients who had improved dyspnea and functional status by TDI and EGOG scores, radiographic response was complete in three and partial in one. Two of the six were not able to return for follow-up because of weakness but reported improvement by telephone inquiry.ConclusionAmbulatory sclerosis of malignant effusion using a small-bore catheter is a feasible alternative to inpatient sclerosis with a large-bore chest tube, especially in patients with strong preferences for outpatient care.
