Complications of implanted subcutaneous port for intraperitoneal chemotherapy in gastric cancer patients with peritoneal metastasis and analysis of risk factors of complications

Objective To analyze the port complications and risk factors associated with the port complications in gastric cancer patients with peritoneal metastasis. Methods The medical records of 323 patients with subcutaneous ports implantation for intraperitoneal chemotherapy were retrospectively analyzed and 261 gastric cancer patients with peritoneal metastasis were included. Port complications and risk factors associated with complications were analyzed. Results There were 59 (22.6%) cases with port complications associated with intraperitoneal chemotherapy in all included 261 cases. Subcutaneous effusion (25 cases, 42.4%) and port infection (16 cases, 27.1%) were the main complications, followed by port rotation (9 cases, 15.3%), partial port wound dehiscence (7 cases, 11.9%), catheter obstruction (1 case, 1.7%) and subcutaneous metastasis (1 case, 1.7%). The median period between port implantation and occurrence of complications was 3.0 months. Eastern Cooperative Oncology Group (ECOG) score, serum albumin, implantation management optimization and implantation specialized group were independent risk factors for port complications (P
