简要总结
In our previous study, a nomogram model was established to predict intra-abdominal infectious complications after gastrointestinal surgery. This model was based on the clinical data and the drainage fluid cytokine levels, and it received an AUC >0.9. In this study, validation of this nomogram is planned to be conducted in this prospective cohort study.
详细描述
Intra-abdominal infectious complications such as anastomotic leakage are the most feared but common complications after gastrointestinal surgery. In our previous study, a nomogram model was established to predict intra-abdominal complications after gastrointestinal surgery. This model was based on the clinical data and the drainage fluid cytokine levels, and it received an AUC >0.9. A predicting score (i.e. APPEAL-GC score) was created based on the model. In this study, validation of this score in predicting intra-abdominal complications is planned to be conducted in this prospective cohort study.
In this study, all patients undergoing gastric or colorectal cancer surgery with a primary anastomosis will be included. The clinical data and complication data will be prospectively collected; the discarded drainage fluid will be collected and analyzed afterward. No additional intervention will be applied.
The cytokine levels in the drainage fluid will be evaluated, and together with the clinical data, an APPEAL-GC score will be created for each patient. We will investigate whether the above-mentioned score is able to predict the intraabdominal complications after surgery. The predictive value (clinical usefulness) of the score will be validated in this study.

结局指标
主要结局
Predictive value of the nomogram prediction model (APPEAL-GC score)
时间窗: From surgery until discharge, up to 90 days.
The positive predictive value of the APPEAL-GC score in predicting the intra-abdominal infectious complications. Intra-Abdominal infectious complications include anastomotic leakage and other abdominal infectious complications. The complication definitions are in accordance with the Chinese consensus of gastrointestinal complication diagnosis and registration. The APPEAL-GC score was derived from our recently finished study (unpublished). It includes evaluation of the surgical type (open or laparoscopic), resection range, age, and cytokine levels on the postoperative day 3. A score of each patient can be determined, and a pre-set cut-off value (unpublished data) was determined in our previous study based on the AUC analysis. In this study, each patient will be scored accordingly. The positive predictive value and negative predictive value of the cut-off value will be evaluated.
次要结局
