ABSTRACT
INTRODUCTION: In patients with peritoneal carcinomatosis (PC), the incidence of respiratory complications following cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is not well established. We aimed to describe the center-specific incidence and patient characteristics associated with respiratory complications following CRS and HIPEC in patients receiving treatment for PC. MATERIALS AND METHODS: We used the University Hospital of Arrixaca study database to identify patients who underwent CRS and HIPEC for PC. Patients who experienced a post-operative respiratory complication were categorized according to the National Cancer Institute-Common Terminology Criteria for Adverse Events. Multivariable regression methods were used to identify independent risk factors for developing a respiratory complication following CRS and HIPEC. RESULTS: Between 2008 and 2017, we identified 247 patients who underwent CRS and HIPEC for PC. A total of eight patients (3.2%) were categorized as having a post-operative respiratory complication. A diaphragmatic peritonectomy and a PC index of > 14 were identified as independent risk factors for developing a respiratory complication. Radiographic evidence of a pleural effusion was identified in 72 patients who had CRS of the diaphragmatic peritoneum; however, only 6 (8.3%) of these patients required pleural drainage. CONCLUSIONS: Only 3.2% of patients developed a symptomatic respiratory complication following CRS and HIPEC. A pleural effusion was identified in almost all patients requiring a diaphragmatic peritonectomy as part of their CRS; however, less than one in ten of these patients required pleural drainage. Prophylactic insertion of a pleural drainage tube is, therefore, not indicated following CRS and HIPEC.
