Abstract: To evaluate the safety and satisfaction of the pre-punched intradermal suture technique in abdominal incision closure of patients with Crohn’s disease. Methods    The clinical data of 194 patients with Crohn’s disease at the Inflammatory Bowel Disease Treatment Center of Jinling Hospital from January 2021 to June 2022 were retrospectively analyzed. According to the suture method, patients were divided into the interrupted suture group (n=129) and the pre-punched intradermal suture group (with a 3 mm hole reserved in the incision during intradermal suturing) (n=65). Baseline data, the incidence of incision-related complications, and patients’ satisfaction with incision between the two groups were compared. Results    The baseline characteristics and the incidence of incision-related complications between the two groups showed no statistically significant differences (P>0.05). Compared to interrupted sutures, patients in the pre-punched intradermal suture group reported higher satisfaction with wound cosmesis, and the difference was statistically significant ［10 (8, 10) vs. 6 (5, 8), P<0.001］. Multivariable logistic regression analysis showed that wound infection was an independent risk factor associated with poor wound cosmesis (OR=4.762, 95% CI 1.099-20.833, P=0.037), while pre-punched intradermal suture was an independent protective factor associated with improved wound cosmesis (OR=0.056, 95% CI 0.026-0.121, P<0.001). Conclusion    Pre-punched intradermal suture can be safely applied to abdominal incision closure in patients with Crohn’s disease, offering higher satisfaction with wound cosmesis and demonstrating clinical applicability.
