Abstract

Background: Small cohort studies have shown rapid pleurodesis protocol's (RPP) effectiveness and capacity to expedite pleurodesis for malignant pleural effusion (MPE). This study intends to evaluate the effectiveness of the RPP in inducing pleurodesis in patients with pleural effusions from either malignant or benign etiologies.

Methods: In this single-center, retrospective cohort study spanning 2 decades, we assessed patients with recurrent symptomatic chronic noninfectious pleural effusion, both benign and malignant. Post-RPP, chest tubes were removed when fluid output dropped below 150 mL/d, and patients were discharged with daily indwelling pleural catheter (IPC) drainage. Exclusion criteria included nonexpandable lung and active pleural infection. Treatment success was defined as IPC removal on reduced output (<50 mL) on 3 consecutive drainages and radiologic effusion resolution. Recurrence was defined as the occurrence of pleural effusion requiring additional pleural procedures postsuccess. Duration outcome was expressed as median with IPC placement as time zero.

Results: Of the 210 patients studied, 72% had MPE, and 28% had benign effusions. The median hospital stay was 4 days post-RPP. Treatment was successful in 177 (84%) patients within a median of 12 days, with no significant differences between MPE and benign cases. Nine patients (5%) experienced recurrence within a median of 152 days. Complications included hemothorax in 4 (1.9%) and empyema in 2 (1%). The thirty-day mortality rate was 9%, with a median survival time of 245 days postprocedure.

Conclusion: The RPP combines the benefit of chemical pleurodesis and IPC and appears to be a reasonable option for patients with recurrent and symptomatic pleural effusion.
