Application of methylene blue guidance combined with closed negative pressure drainage in the treatment of inguinal hernia mesh infection
Abstract
Purpose: To explore the application and effect of methylene blue guidance combined with closed negative pressure drainage in the treatment of inguinal hernia mesh infection.
Method: The clinical data of 38 patients with mesh infection after inguinal hernia repair who were admitted to the Department of Vascular Thyroid Hernia and Abdominal Wall Surgery of Guangdong General Hospital from January 2015 to June 2019 were retrospectively analyzed. Among them, 38 patients were treated with methylene blue guidance combined with negative pressure drainage and debridement. We evaluated the clinical characteristics and wound healing degree of all patients after primary suture of postoperative wounds, and their average operation time, average hospital stays and postoperative complications were recorded to evaluate the therapeutic effect.
Result: Methylene blue injection into sinus was adopted for all patients, followed by removal of all methylene blue stained sinus and tissue, postoperative primary suture, and negative pressure closed drainage. After treatment, all 38 patients finished the surgery successfully, with an average operation time of 55 min (35-70 min) and an average hospital stay of 24 h to 72 h. All patients recovered well after surgery, without occurrence of postoperative complications like hydrops under incision, wound reinfection, intestinal fistula, postoperative pain, recurrence, and death, indicating well postoperative recovery. The followup period continued for 3 to 36 months.
Conclusion: Methylene blue guidance combined with closed negative pressure drainage and debridement to completely remove the mesh is the key to the treatment of mesh infection. Its satisfactory therapeutic effect and convenience prove its worth to be popularized in hospitals at all levels.
