Efficacy of surgical resection and ultra-reduced tension suture combined with superficial radiation in keloid treatment

BACKGROUND There are many available treatment options for keloid;however,single treatments are usually less effective.Therefore,more scientifically rational and effective com-bined treatment methods should be sought to solve the pain associated with keloids.AIM To explore the efficacy and safety of surgical resection and ultra-reduced tension suture combined with superficial radiation as keloid treatment.METHODS Fifteen keloid patients admitted to Qingdao Eighth People's Hospital from June 2020 to January 2022 were enrolled in this retrospective analysis.All patients underwent a comprehensive treatment approach comprising surgical resection,ultra-reduced tension suture incision,and superficial radiation therapy within 24 h postoperatively.The modified Vancouver Scar Scale(mVSS)and Patient and Observer Scar Assessment Scale(POSAS)were used to evaluate the treatment effect,whereas the efficacy,adverse effects,and recurrence rate were observed according to the 12-mo follow-up after treatment.RESULTS The mVSS and POSAS scores at 1 and 6 mo after combination treatment decreased compared to before treatment(P<0.001),and the overall response rate was 93.3%.Only one case recurred,yielding a 6.7%recurrence rate.The incidence of local chromour sedimentation rate in 1–3 mo after radiotherapy was 33.3%(5 patients),all subsiding after 6–9 mo,without complications,such as delayed wound healing or dermatitis.CONCLUSION Surgical resection,super subtraction sutures,and superficial radiotherapy are treatment methods with short courses,low recurrence rates,and good safety profiles.

Clinical study of polydloxanone suture tension band fixation for treatment of patellar fractures

To explore biomechanic characteristics and clinical outcome of absorbable polydloxanone (PDS) treating patellar fractures.Methods The tensile strength test of PDS 0-0 or PDS 1-0 sutures were made in WDW305 electro-universal tester.A total of 60 cases were classified randomly and equally into two groups:treatment group (treated with the absorbable PDS tension hand) and Kirschner wire metals tension band control group (control group).Anatomy reduction was performed with towel clip fixation during operation.Treatment group was managed with diameter 1.5 mm Kirschner wires drilling two pores on the near or distal segment of patellar fracture end are penetrating through two strands of absorbable PDS 0-0 or PDS 1-0 sutures for a satisfactory fracture fixation.Control group was treated with Kirschner wires (2.0 mm in diameter) and steel wire (1.0 mm in diameter) of type “8” tension band fixation.Results Tensile strength testing showed that the biggest tensile of a strand PDS 0-0 sutures was 71.50 N and that of PDS 1-0 97.48 N,when the length was three times more than the initial.Two groups were followed up and the mean fracture healing time was two months,without broken wire or dislocation.Treatment group showed excellent clinical results in 21 cases,good in six and fair in three;while control group showed excellent clinical results in 19 cases,good in seven and fair in four,with no statistical difference compared with treatment group (χ2=0.32,P>0.05).Conclusion Absorbable PDS tension band has better characteristics of mechanics and creepage in treating patellar fractures.It can avoid defects of secondary operation and complications like needle-tail pain and sharped skin resulted from metal tension band fixation.Meanwhile,it is economic and worthy of further clinical application.16 refs,4 figs.
