Abstract : Surgery or invasive procedures can pose risks to patients with hemophilia. Circumcision performed on patients with hemophilia can pose risks such as prolonged bleeding, infection, longer wound healing and increased morbidity. Data on circumcision in pediatric patients with hemophilia in Indonesia are still very few. The purpose of this study was to provide an overview of the clinical condition of children with post-circumcision hemophilia. This is a descriptive study who observed 9 hemophilia patients underwent circumcision in Haji Adam Malik General Hospital. The demographics data of the patients were collected from medial record including age, family history of hemophilia, type and severity of hemophilia. Among 9 hemophilia patients who underwent circumcision in Haji Adam Malik General Hospital Medan, 66.67% cases were diagnosed as hemophilia at under 10 years old. From 33.33% of the cases, the diseases were in mild and severe conditions. After the circumcision, all the patients were hospitalized and monitored by the vital signs and signs of bleeding. About 66.67% cases were hospitalized for <5 days, and 33.33% for 5-7 days. In our study, we found 55.56% cases have minimal bleeding on surgical wound, 11,11% cases have an active bleeding on surgical wound, 11.11% cases have spontaneous bleeding, and 22.22% cases have no bleeding. The subtitutive treatment by Factor VIII and Factor IX concenctrates were given one hour before circumcision and continue to be given in the following days, 66.67% patients are given for <5 days and 33.33% patients for 5-7 days. Circumcision of children with bleeding disorders especially hemophillia should be done carefully by surgeons and hematologist under appropriate conditions at comprehensive hemophilia centers even though bleeding diatheses are not an absolute contraindications for the procedure.
