Abstract
Objectives: This study aims to investigate the factors that may be associated with surgical site infection and mortality in pelvic resection surgeries. Patients and methods: A t otal o f 6 8 p atients ( 40 m ales, 28 females; mean age: 43±16.2 years; range, 11 to 70 years) who underwent internal or external hemipelvectomy between January 2010 and January 2020 were retrospectively analyzed. We reviewed data concerning histopathological diagnosis, surgical technique, pelvic resection type, tumor size, postoperative infection, duration of follow-up, and mortality. Results: The mean follow-up was 45.5±42.2 months. Among 68 patients, 29 (42.6%) cases underwent external hemipelvectomy and 39 (57.4%) cases underwent internal hemipelvectomy. Reconstruction was performed in 14 (20.6%) patients who underwent internal hemipelvectomy. Of all patients, 61 had primary malignant pelvic tumors and two had metastatic pelvic tumors. Of the other five patients, two had a giant cell tumor, two had a pelvic hydatid cyst, and one had an aneurysmal bone cyst. The three most common pelvic tumors were chondrosarcoma (n=25, 36.7%), osteosarcoma (n=13, 19.1%), and Ewing sarcoma (n=8, 11.8%). Surgical site infections were observed in 34 (50.0%) patients. Of 34 patients, 15 (22.1%) had superficial infections and 19 (27.9%) had deep surgical infections. The superficial and deep infection rates were higher in the external hemipelvectomy group compared to internal hemipelvectomy (p=0.02). Patients with postoperative infection had a mean survival period of 36.0 months compared to 79.8 months in patients without infection (p=0.037). The patients treated with internal hemipelvectomy had a mean survival of 97.0 months compared to 25.7 months in patients treated with external hemipelvectomy (p
