Aim. To assess the effectiveness of multidisciplinary team approach in daily practice of diabetic foot. Materials and methods. 376 diabetic patients (446 ulcers) treated in a diabetic foot department in 2014 were examined. All patients were screened for diabetic peripheral polyneuropathy and blood insufficiency of lower extremities in order to diagnose the type of diabetic foot ulcer: neuropathic or neuroischemic. Patients were treated by a multidisciplinary team. The number of healed ulcers, minor and major amputations was analyzed. Results. 80% of diabetic foot ulcers were neuropathic with normal blood supply, 20% had signs of ischemia. 77,8% of the ulcers healed in the general group during the study period. 13 amputations (2,9%) were done in the study group: 7 minor amputations (1,6%), 2 below the knee (0,4%), and 4 above knee (0,9%). Two patients died from cardiovascular events (0,4%). The comparative analysis of outcomes of neuropathic and neuroischemic ulcers showed that 84% of neuropathic ulcers healed. Minor amputations were done in 1% of the cases, no major amputations were performed. In patients with neuroischemic ulcers, 60% of them healed, minor amputations were made in 3,4% of cases (2,3% below knee, 4,6 % above knee). Conclusion. The majority of diabetic ulcers in the study group were neuropathic with normal blood supply. The main risk factor of major amputations is ischemia of the affected limb. The multidisciplinary team approach in daily practice of the diabetic foot department of an out-patient clinic is instrumental in healing ulcers and minimizing the risk of major amputations.

e12613 Background: Breast cancer is in first place among malignant diseases in women in Russia. We can provide, in most cases, breast-conserving surgery (BCS), due to progress in early diagnosis. Evaluation of positive margins is still one of the most important objectives in breast-conserving surgery. Objectives: To assess the benefits of IDSR in BCS of patients with “carcinoma in situ”. Methods: The results of treatment of 55 patients with breast cancer “carcinoma in situ” in our clinic were evaluated in two comparable groups. Group A included 28 patients, who were operated on from January 2019 to June 2019 and had breast-conserving surgery without IDSR. Group B included 27 patients, who were operated on from June 2019 to January 2020 and had breast-conserving surgery with the evaluation of margins by IDSR. Results: In a planned histological examination positive margins were detected in group A in 4 cases (14%) and required reoperation. In group B all margins were clear. After IDSR, 6 (22%) patients out of 27 in this group showed microcalcifications in the resection margins or at a distance of less than 1 mm and required intraoperative additional excision to obtain clean margins. Conclusions: IDSR reduces the frequency of reoperation due to increased detection of positive margins, allows to correct scope and duration of surgery because of impact on the time of the surgical decision-making process.
