Configuration of anastomotic doughnuts of stapled anastomoses in upper gastrointestinal surgery is associated with anastomotic leakage.

OBJECTIVE: The aim of this study was to evaluate whether the configuration of anastomotic doughnuts from upper gastrointestinal surgeries was associated with anastomotic leakage (AL). BACKGROUND: AL is a severe postoperative complication after upper gastrointestinal cancer surgeries. AL is associated with an increase in overall and cancer-related morbidity and mortality in patients with esophageal and gastric cancer. New intraoperative biomarkers are needed to predict the risk of AL to implement early preventive measures. MATERIALS AND METHODS: Anastomotic doughnuts from 102 patients undergoing surgery for esophageal or gastric cancer using circular staplers were examined. The minimal and maximal height and width of the anastomotic doughnuts were measured and correlated with the postoperative AL rate. RESULTS: The AL rate in our study collective was 15,7 %. The minimal width (Wmin) of the oral and aboral anastomotic doughnuts was significantly lower in patients with AL compared to patients without AL (p = 0.002 and p = 0.041 respectively). The Wmin of the esophageal anastomotic doughnut was an independent risk factor for AL in the multivariable analysis (p = 0.034). Negative predictive values for the measurements of anastomotic doughnuts (Wmin) with regard to the risk of AL were higher than for the commonly used postoperative biomarker C-reactive protein. CONCLUSION: Minimal anastomotic doughnut width was statistically significantly associated with AL. Thus, not only the evaluation of the completeness of the anastomotic doughnuts but also intraoperative measurements could be used to predict the risk of AL to initiate early preventive measures to prevent the development of AL and/or reduce AL-associated morbidity.      «
