Preliminary Study on the Application of Nanochitosan Film and Petrolatum Gauze in the Modified Devine Operation

Although the use of sterile petroleum jelly gauze combined with nanochitosan film to wrap wounds has been proven to have good results, it has not been applied for modified Devine surgery. The use of sterile petroleum jelly gauze alone in the modified Devine surgery to treat concealed penis in children has different effects. In this study, the systematic evaluation of the effect of the modified Devine technique (Vaseline gauze bandaging the wound) in the treatment of concealed penis in children is conducted. Furthermore, the application of nanochitosan film and Vaseline gauze in the modified Devine technique is proposed. By analytical search in PubMed, China Knowledge Network (CKN), and other Chinese and foreign literature databases, there are 13 studies describing the development of the penis during the follow-up period with high satisfaction of patients and their family members. In addition, systematic evaluations have shown that the complete removal of the fibrotic penile sarcoid tissue is an important reason for the remarkable curative effect of the modified Devine surgery in the treatment of concealed penis in children.
