Use of pleural Tenckhoff catheter to palliate malignant pleural effusion

Malignant pleural effusion and its treatment both cause substantial morbidity in patients with advanced neoplastic disease. We hypothesized that this morbidity might be ameliorated by placement of an indwelling Tenckhoff catheter into the involved pleural space. Catheters were placed in 9 patients under local anesthesia. Three patients underwent bilateral catheter placement, for a total of 12 catheters placed. Four of the 9 patients had undergone previous unsuccessful pleurodesis (using tetracycline or bleomycin). Whenever it became symptomatic, the malignant pleural effusion was simply drained into a calibrated container and the volume recorded. Patients were followed on a weekly basis until their death (mean, 16 weeks). The mean drainage was 477 mL per 24 hours (range, 200 to 1,100 mL). No pleural space infections occurred, although local cellulitis developed in 3 patients around the catheter exit site; all patients responded to oral antibiotics. There were no significant changes in either the serum albumin or total protein levels. No catheters malfunctioned and no patients required further treatment or hospitalization for symptoms of malignant pleural effusion. We conclude that this technique may reduce the morbidity stemming from malignant pleural effusion and its treatment by allowing patients to conveniently and painlessly drain the effusion at home when it becomes symptomatic. This technique may provide superior palliation in patients with malignant pleural effusion.
