Application and Prognostic Analysis of Vacuum Sealing Drainage in the Incision Infection in Patients With Stage II-III Colorectal Cancer.

Introduction: This study aims to explore the application value of vacuum sealing drainage (VSD) technology in the treatment of incision infection dehiscence after surgery in patients with stage II-III colorectal cancer and analyze its impact on prognosis.

Methods: This retrospective study included patients who experienced incision infection dehiscence after surgery for colorectal cancer between February 2014 and August 2019. Clinical and pathological data, short-term outcomes, and long-term outcomes were compared between the traditional group and the VSD group.

Results: A total of 97 patients were included in this study. There was no significant difference in clinical and pathological data between the traditional group and the VSD group (P > 0.05). The VSD group had fewer dressing changes, lower pain scores during dressing changes, and better granulation tissue growth grading than the traditional group, with statistical significance (P < 0.05). The VSD group started adjuvant chemotherapy earlier and had a higher proportion of ≥4 cycles of chemotherapy. The three-year overall survival rate in the VSD group was better than the traditional group, but the difference was not statistically significant (P > 0.05).

Conclusion: The application of VSD technology can promote granulation tissue growth, accelerate incision healing, and facilitate patients to complete subsequent adjuvant chemotherapy. However, further verification of its long-term impact on prognosis requires longer-term follow-up results.
