CANCER, TUMOR, PERIAMPULLARY CARCINOMA
There are several limitations in this study. Firstly, the inflammatory indicators we examined were relatively single, and there may be differences in other immune cells and cytokines. Furthermore, long-term indicators are important for cancer prognosis, and we only collect short-term outcome indicators and pay more attention to the immune-related situation, did not follow up after discharge from the hospital. Secondly, patients undergoing LPD include different types of periampullary carcinomas, and the bias caused by cancer type cannot be completely ruled out, although the distribution of tumor types in two groups was similar. Thirdly, we only collected and measured samples every 24 h after surgery. For the lack of detection within 24 h after surgery, the dynamic changes of inflammatory factors and immune cells may not be observed in time.
