Introduction: Hepatic arterial infusion (HAI) chemotherapy is associated with improved survival in stage IV colon cancer with liver metastases. Whether simultaneous colon resection and HAI pump (HAIP) placement is associated with increased morbidity has not been specifically studied. The purpose of this study was to compare perioperative outcomes of simultaneous colon resection and HAIP placement versus HAIP placement alone. Methods: This was a retrospective study of consecutive patients with colon cancer and synchronous liver metastases who underwent HAIP placement between 2007 and 2018. Clinicopathologic characteristics, operative data, complications, and time to first cycle of HAIP chemotherapy were compared between patients who underwent colon resection simultaneously with HAIP placement and those who underwent HAIP placement alone. Results: A total of 258 patients underwent simultaneous colectomy and HAIP placement, and 116 patients underwent HAIP placement alone. Grade 1–2 complications were more common in patients who underwent simultaneous colectomy and HAIP placement (36.8% vs. 19.0%, P < 0.001), but grade 3–4 complications were not observed more frequently (14.3% vs. 12.9%, P = 0.872). The median interval between HAIP placement and start of HAIP chemotherapy did not differ between groups (simultaneous colectomy, 27 days [interquartile range (IQR) 17–34]; HAIP placement alone, 30 days [IQR 21–34]; P = 0.924). Infection of the pump causing either delay of initiation of chemotherapy or explantation of the pump occurred in five patients with simultaneous colectomy and in one patient with HAIP placement alone (P = 0.671). Conclusions: Simultaneous HAIP implantation and colectomy is safe in patients with liver metastases of colon carcinoma.
