Risk Factors of Syme Amputation in Patients with a Diabetic Foot / 대한족부족관절학회지

ABSTRACT

PURPOSE: This study examined the factors affecting the treatment of diabetes mellitus foot patients who had undergone a Syme amputation. MATERIALS AND METHODS: This study included 17 patients diagnosed with a diabetes mellitus foot and who had undergone a Syme amputation from January 2010 to January 2014. Some of the risk factors (age, body mass index [BMI], disease duration, smoking, ankle brachial index [ABI], HbA1c, serum albumin, total lymphocyte, C-reactive protein [CRP], and serum creatine) that affect the successful Syme amputation were analyzed. RESULTS: The healing rate of a Syme amputation was significantly higher when the lymphocyte count was above 1,500 mm3 (p=0.029). The factors affecting the surgical outcome according to multivariate analysis were HbA1c and the BMI (p=0.014, p=0.013). Regarding reamputation, there was a significant difference with HbA1c, lymphocyte, and BMI (p=0.01, p=0.03, and p=0.01). No significant differences were observed with age, disease duration of diabetes mellitus, smoking, ABI, serum albumin, CRP, and serum creatine. CONCLUSION: The HbA1c level, BMI and total lymphocyte count are risk factors that must be considered for successful Syme amputation in patients with diabetic foot disease.
