The postoperative application value of the vacuum sealing drainage technique in patients with giant malignant thyroid

ObjectiveTo explore the application effects of vacuum sealing drainage (VSD) technique on wound healing of cervical giant thyroid carcinoma after operation.

MethodsEighty-nine cervical giant thyroid carcinoma patients treated with radical surgery were randomly divided into the control group(n=44) and observation group(n=45).The control group was treated with radical tissue flap, and the observation group was treated with radical tissue flap combined with VSD covering wound.After operation, the observation group was continously drainaged under the pressure of 6.65 to 7.98 mmHg for 72 h, then intermittently drainaged.After 1 to 2 weeks of operation, the VSD was stopped according to the postoperative wound recovery, and the wound was treated with skin graft according to the growth of granulation tissue.The wound repair between two groups was compared.

ResultsThe VSD in 39 cases of observation group was stopped after 2 weeks of operation, the wound granulation tissue survival was good, completely covered the important organization and blood vessels of neck, and no pus secretion was found.The wound was timely grafted with skin, and the skin healing was good.The granulation tissue growth in 6 cases was poor in observation group after 2 weeks of operation, the wound was treated with debridement for 1 for 2 times and VSD, the skin graft surgery was successfully implemented after granulation tissue growth was good.Thirteen cases with wound infection in control group were found, the wound healed after repeated dressing wounds, and the obvious scars were identified.The skin flap necrosis in 7 cases were identified in control group, and the debridement and flap transplantation should be performed again.The difference of the infection rate of wound between two groups was statistically significant(P < 0.01).The average healing time of skin in observation group(3.57±1.83) weeks was significantly lower than that in control group(6.75±2.42) weeks (t=7.00, P < 0.01).

ConclusionsThe application of VSD technique after resection of giant thyroid carcinoma can reduce the probability of infection, promote the wound healing, and improve the tolerance of patients.It is a simple, safe and effective method for repairing postoperative tissue defect of giant thyroid carcinoma.
