| Objective To explore the high-risk factors of postoperative small intestinal intussusception in adults. Methods A total of 9 825 patients with gastric diseases (including malignant tumors, ulcers, and perforations) who underwent gastric surgery from January 2010 to December 2018 in the First Affiliated Hospital of Anhui Medical University were selected. Postoperative patients with small intestinal intussusception were enrolled in test group, and no intussusception patients were enrolled in control group matched by gender and age at the rate of 1:4 with case group. Data were analyzed to explore the relationship between postoperative intussuscepion and gender, BMI, surgical methods etc. Results The median BMI of case group was 21.67 (19.81, 23.09) kg/m2, which was lower than that of control group with statistically significant difference(P<0.05). In case group, 3 cases (33.33%) had intussusception on the stapler, which was higher than 2 cases (5.56%) in control group, and the difference was statistically significant (P<0.05). Logistic regression analysis showed that intraoperative intussusception and low BMI were risk factors of postoperative intussusception. Conclusion Patients with high preoperative BMI have lower risk of postoperative intussusceptions, while those with intraoperative intussusceptions are more likely to have postoperative intussusception. |
