<p><strong>Background.</strong> The frozen elephant trunk (FET) technique for the treatment of both thoracic aortic aneurysms and dissections has become universally popular over the past two decades because extensive open surgical reconstruction of the thoracic aorta has been found to be associated with high complication and mortality rates or unfavourable long-term outcomes as it requires repeated interventions. The FET technique has also been shown to produce excellent, immediate and long-term results. Hence, it is important to evaluate the outcomes of thoracic aortic reconstruction using this technique.<br /><strong>Aim.</strong> This study aimed to investigate immediate and long-term outcomes of the FET technique in patients with thoracic aortic diseases.<br /><strong>Methods.</strong> We retrospectively analysed the pre-, intra- and post-operative data of 40 patients with distal aortic arch aneurysm who had undergone aortic arch reconstruction using the FET technique at Meshalkin National Research Medical Center from February 2012 to October 2020. To assess the early and long-term post-operative survival of these patients, we categorised them into group I (including 14 patients without aortic dissection) and group II (including 26 patients with type I and type III aortic dissections).<br /><strong>Results.</strong> The in-hospital survival rates for groups I and II were found to be 68.5% and 95.9%, respectively (log rank, p = 0.048). Groups I and II did not differ significantly in the incidence of stroke (7.1% vs 7.7%, respectively; p = 0.724) and spinal cord ischaemia (14.3% vs 0%, respectively; p = 0.117). Long-term (1-, 3- and 5-year) survival rates in group II remained unchanged at 95.9%, whereas survival rates at 30 days, 6 months and 1 year in group I were 91.3%, 68.5% and 57%, respectively. The risk of mortality was 90% lower in group II than in group I, with a hazard ratio of 0.096 and a 95% confidence interval of 0.01–0.81 (p = 0.038). The rates of freedom from thoracoabdominal aortic interventions in group II were 91.8%, 83%, 64.7%, 59.3% and 59.3% at 30 days, 6 months, 1 year, 3 years and 5 years, respectively; these rates in group I were 90.9%, 75.7% and 75.7% at 30 days, 6 months and 1 year, respectively. There was no significant difference between the groups concerning thoracoabdominal aortic interventions (log rank, p = 0.587).<br /><strong>Conclusion.</strong> The use of the FET technique in patients with thoracic aortic diseases is associated with acceptable rates of mortality and thoracoabdominal aortic interventions in immediate and long-term post-operative periods.</p><p>Received 28 January 2021.

Background: This study aimed to evaluate the early and long-term outcomes of a single center using a frozen elephant trunk (FET) procedure for chronic type B or non-A non-B aortic dissection.Methods: From February 2009 to December 2019, 79 patients diagnosed with chronic type B or non-A non-B aortic dissection who underwent the FET procedure were included in the present study. We analyzed operation mortality and early and long-term outcomes, including complications, survival and interventions.Results: The operation mortality rate was 5.1% (4/79). Spinal cord injury occurred in 3.8% (3/79), stroke in 2.5% (2/79), and acute renal failure in 5.1% (4/79). The median follow-up time was 53 months. The overall survival rates were 96.2, 92.3, 88.0, 79.8, and 76.2% at 1/2, 1, 3, 5 and 7 years, respectively. Moreover, 79.3% of patients did not require distal aortic reintervention at 7 years. The overall survival in the subacute group was superior to that in the chronic group (P = 0.047).Conclusion: The FET technique is a safe and feasible approach for treating chronic type B and non-A non-B aortic dissection in patients who have contraindications for primary endovascular aortic repair. The technique combines the advantages of both open surgical repair and endovascular intervention, providing comparable early and long-term follow-up outcomes and freedom from reintervention.

The Impact

Background. Although mortality and morbidity of pancreatoduodenectomy (PD) have improved significantly over the past years, the impact of age for patients undergoing PD is still debated. This study is aimed at analyzing short- and long-term outcomes of PD in elderly patients. Methods. 124 consecutive patients who have undergone PD for pancreas neoplasms in our center between 2012 and 2017 were analyzed. Patients were divided into two groups: group I (<75 years) and group II (≥75 years). Demographic features and intraoperative and clinical-pathological data were collected. Primary endpoints were perioperative morbidity and mortality; complications were classified according to the Clavien-Dindo Score. Secondary endpoints included feasibility of adjuvant treatment and overall survival rates. Results. A total of 106 patients were included in this study. There were 73 (68.9%) patients in group I and 33 (31.1%) in group II. Perioperative deceases were 4 (3.6%), and postoperative pancreatic fistulas were 34 (32.1%). Significant difference between two groups was demonstrated for the ASA Score (p=0.004), Karnofsky Score (p=0.025), preoperative jaundice (p=0.004), and pulmonary complications (p=0.034). No significance was shown for diabetes, radicality of resection, stage of disease, operative time, length of stay, postoperative complications according to the Clavien-Dindo Score, postoperative mortality, pancreatic fistula, and reoperation rates. 69.9% of the patients in group I underwent adjuvant treatment vs. 39.4% of the older ones (p=0.012). Mean overall survival was 28.5 months in group I vs. 22 months in group II (p=0.909). Conclusion. PD can be performed safely in elderly patients. Advanced age should not be an absolute contraindication for PD, even if greater frailty should be considered. The outcome of elderly patients who have undergone PD is similar to that of younger patients, even though adjuvant treatment administration is significantly lower, demonstrating that surgery remains the main therapeutic option.

Introduction. Currently, the most common method of treating extended urethral strictures is augmentation urethroplasty using oral mucosa grafts. Analysis of the long-term outcomes of this surgery type shows a high incidence of relapses and complications.Purpose of the study. To improve the outcomes of augmentation urethroplasty, in particular the dorsal inlay (Asopa) technique, in patients with extended spongy urethral strictures by minimizing the risk of recurrent strictures.Materials and methods. The study is based on an analysis of the surgery in 90 patients (aged 18-72 years) with extended spongy urethral strictures. Seventy patients (group I) underwent dorsal inlay augmentation urethroplasty according to the Asopa technique, and 20 patients (group II) — according to the author's modified technique. Statistical data analysis was carried out using the SPSS ver.26 software (SPSS Inc. Chicago, IL, USA).Results. A comparative analysis of the course of the early postoperative period showed a lower number of complications in group II patients compared to group I — 20.0% versus 34.3%, respectively. The recurrent strictures were registered for groups I and II in 18.8% and 5.6% of cases 6 months after surgery, respectively. The recurrent urethral narrowing was most often localized in the area of distal anastomosis between the buccal graft and the native urethra in patients from both groups.Conclusion. The modified dorsal inlay augmentation urethroplasty technique developed and implemented in clinical practice by increasing the internal urethral lumen in the areas of proximal and distal anastomosis between the buccal graft and the native spongy urethral body allows minimizing the risks of recurrent urethral narrowing after augmentation urethroplasty.

AbstractIn the ENESTnd study, with ≥10 years follow-up in patients with newly diagnosed chronic myeloid leukemia (CML) in chronic phase, nilotinib demonstrated higher cumulative molecular response rates, lower rates of disease progression and CML-related death, and increased eligibility for treatment-free remission (TFR). Cumulative 10-year rates of MMR and MR4.5 were higher with nilotinib (300 mg twice daily [BID], 77.7% and 61.0%, respectively; 400 mg BID, 79.7% and 61.2%, respectively) than with imatinib (400 mg once daily [QD], 62.5% and 39.2%, respectively). Cumulative rates of TFR eligibility at 10 years were higher with nilotinib (300 mg BID, 48.6%; 400 mg BID, 47.3%) vs imatinib (29.7%). Estimated 10-year overall survival rates in nilotinib and imatinib arms were 87.6%, 90.3%, and 88.3%, respectively. Overall frequency of adverse events was similar with nilotinib and imatinib. By 10 years, higher cumulative rates of cardiovascular events were reported with nilotinib (300 mg BID, 16.5%; 400 mg BID, 23.5%) vs imatinib (3.6%), including in Framingham low-risk patients. Overall efficacy and safety results support the use of nilotinib 300 mg BID as frontline therapy for optimal long-term outcomes, especially in patients aiming for TFR. The benefit-risk profile in context of individual treatment goals should be carefully assessed.
