Predictive Factors and Amputation Level for Reamputation in Patients With Diabetic Foot: A Retrospective Case-Control Study.

The aim of this study was to assess the rate and level of reamputation in patients who had a previous amputation from diabetic foot. We retrospectively analyzed patients who underwent amputation and reamputation due to diabetic foot in our clinic between 2011 and 2019. Fifty-nine were evaluated as the healed group after the first amputation and 55 were evaluated as the reamputation group. Given 55 patients who needed reamputation: there were 13 finger or ray, 23 transmetatarsal or syme, 18 transtibial, and 1 transfemoral in the first operation. We found the reamputation rate was 65.4% in distal amputations. When serum parameters were examined before the first amputation in each group, there was no statistically significant difference in white blood cells, neutrophils, lymphocytes, platelets, sedimentation, C-reactive protein, total protein, hematocrit, urea, creatinine, and HgA1c values. There was, however, a significant difference between groups in albumin levels. When comorbidities were assessed for smoking, hypertension, duration of diabetes, and number of debridements after the first surgery, a significant difference between groups was found. When peripheral artery disease and chronic renal failure were examined, no significant difference was observed. In our study, it was observed that the rate of reamputation was higher in distal level amputations for diabetic foot patients. Accordingly, albumin values, smoking, hypertension, duration of diabetes, number of debridements after surgery, were seen as risk factors for reamputation patients.
