Identifying the incidence of respiratory complications following diaphragmatic cytoreduction and hyperthermic intraoperative intraperitoneal chemotherapy.

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.
