摘要

Non-occlusive mesenteric ischemia was a serious disease. Studies have examined the treatment and diagnosis of this disease. However, few reports exist on whether the grade of necrosis of the resected intestine affects the postoperative period. The aim of this study to compare postoperative outcome both the transmural infarction and non-transmural infarction group. We conducted a case series analysis of data from 37 patients with suspected non-occlusive mesenteric ischemia who underwent surgery between January 2015 and April 2023. Based on pathological findings, patients were divided into the transmural infarction and non-transmural infarction groups. Patient characteristics and postoperative outcomes were analyzed. The transmural infarction and non-transmural infarction groups had 19 and 18 patients, respectively. The patient characteristics were not significantly different between the two groups. The transmural infarction group had a greater anastomosis leakage rate than the non-transmural infarction group. The mortality and 1-year survival rates were not associated with the necrosis grade. Transmural necrosis was associated with an increased risk of anastomotic leakage, but it did not affect short-term or 1-year mortality. Further research with larger cohorts is warranted to confirm these findings.
