RESUMO
Objective:To explore the curative effects of individualized surgical method for treating pyriform sinus fistula (PSF) in children.Methods:A total of 43 PSF children treated in the Department of Pediatric Surgery of Henan Provincial People′s Hospital from June 2015 to November 2019 were selected, with 41 cases on the left side and 2 cases on the right side.There were 27 cases in the quiescent inflammatory infection stage and 16 cases in the acute inflammatory infection stage.According to patients′ condition, low-temperature plasma radiofrequency ablation, fistulectomy, abscess incision and drainage or combined operation were conducted.The postoperative complications and recurrence were observed.Results:Among 43 cases, there were 19 cases treated with low-temperature plasma radiofrequency ablation, 11 cases treated with low-temperature plasma radiofrequency ablation combined with abscess incision and drainage, 5 cases treated with low-temperature plasma radiofrequency ablation combined with fistulectomy, and 8 cases treated with fistulectomy.Four cases had postoperative hoarseness and recovered within 1-5 months.One case occurred pseudo healing after abscess incision and drainage, and healed after incision and debridement.Totally, 4 cases recurred, and the follow-up time was from 3 months to 57 months.Conclusions:Low-temperature plasma radiofrequency ablation has the advantages of minimally invasive, safe and effective, which provides a new treatment for PSF in children.Based on the condition of children, the choice of individualized treatment can significantly improve the curative effects.
RESUMO
Objective To study the effect and postoperative reaction of nasal endoscopic low temperature plasma radiofrequency ablation on children with snoring. Methods 104 cases with snoring received surgical treatment from May 2013 to May 2015 were divided into experimental group and control group. The experimental group patients re-ceived nasal endoscopic low temperature plasma radiofrequency ablation, the control group received adenoidectomy curettage combined with tonsillectomy. Then the surgery condition, postoperative pain, stress response and ventila-tion function were compared between the two groups. Results Operation indicator: the experimental group operation time, postoperative pain time, symptoms remission time, intraoperative blood loss were significantly lower than the control group ( < 0.05); Pain degree: 6 h, 24 h, 48 h, 72 h after surgery, the experimental group VAS score were significantly lower than that in control group ( < 0.05); Stress reaction: 24 h after surgery, the experimental group patients serum MDA, 8-isoPG, 3-NT content were significantly lower than that in control group, SOD, GSH content were significantly higher than that in control group ( < 0.05); Ventilation function: 6 months after surgery, the ex-perimental group AHI, ODI, SLT90%, LAT were significantly lower than that in control group, LSaO2 were signifi-cantly higher than that in control group ( <0.05). Conclusion Nasal endoscopic low temperature plasma radiofre-quency ablation can reduce surgical trauma and relieve postoperative pain and stress reaction, improve ventilation function, it's an ideal operative method for the treatment of children with snoring.
