Pleural empyema as a complication of pyogenic liver abscess: Can the minimum achieve the optimal? a comparison of 3 approaches

Abstract

Case series Patients: Male, 29-year-old • Male, 42-year-old • Male, 26-year-old Final Diagnosis: Empyema Symptoms: Abdominal pain • dyspnea Medication: — Clinical Procedure: — Specialty: Surgery Objective: Rare coexistence of disease or pathology Background: Pyogenic liver abscess is an uncommon entity that is potentially lethal. Pleural empyema and mediastinal collection are 2 rare complications of hepatic abscess that negatively impact the prognosis. Case Reports: Herein, we report 3 cases of pyogenic liver abscesses complicated by pleural empyema, each approached differ-ently, along with a succinct review of the literature. Case 1: A 29-year-old man diagnosed with Crohn’s disease presented with Crohn’s disease-associated hepatic abscess complicated by pleural empyema and concurrent mediastinal collection. The patient demonstrated significant improvement after administration of intrapleu-ral fibrinolytic therapy. Case 2: A 42-year-old man with unremarkable past medical history presented with abdominal pain and dyspnea. Upon investigation, he was found to have massive pleural empyema secondary to liver abscess. In contrast to case 1, case 2 required pleural debridement via video-assisted thoracoscopic surgery followed by formal decortication through a posterolateral thoracotomy. Thereafter, a dramatic clinical improvement was observed. Case 3: A 26-year-old man with history of brucellosis 6 months before was trans-ferred to our facility as a case of pleural empyema secondary to transdiaphragmatic extension of liver abscess. Unlike case 1 and 2, this patient was managed by drainage of hepatic and pleural collections under radiological guidance only, without the need for intrapleural fibrinolytic therapy or surgical intervention. Conclusions: The current paper sheds light on one of the uncommon complications of hepatic abscess and contributes to this scant literature by summarizing pertinent publications. Adequate drainage remains the cornerstone of any pus collection management despite the complexity of some encountered cases.
