We evaluated preoperative predictors of intestinal ischemia in patients with an incarcerated groin hernia (IGH). Data of a total of 39 patients who underwent an emergency operation for IGH at our hospital from January 2008 through March 2018 were analyzed. The patients were divided into two groups: one group that had undergone resection of the small intestine (n＝22), and another that had not (n＝17). Local pain and skin redness at the first visit were found more frequently in the resected group (resected group: non–resected group＝12：3). The pre–contrast CT value of the incarcerated hernia contents was higher in the resected group than in the non–resected group. We performed a ROC curve analysis and found that the optimum cut–off value was 15 HU. These results indicate that the pre–contrast CT values of incarcerated hernia contents are higher (＞15 HU) and that necrosis of the intestine is associated with remarkable local findings.
