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.

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.

<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.

The effect of long-term treatment with sodium nedocromil on airway hypereactivity was investigated in two groups of 20 patients each. Group I patients presented with allergic asthma while Group II patients presented with intrinsic asthma. For each subject of the two groups, the base FEV1 was measured and nebulized methacholine was administrated in consecutively higher concentrations until a decrease in FEV1 of >20 % was observed. Following measurement, all patients included in the study were treated with 12 mg of sodium nedocromil per day for 12 months. At the end of the treatment, bronchial hyperreactivity was evaluated for a second time by administering the same dosage of methacholine that originally produced a decline in FEV1 of >20 %. In Group I patients (allergic asthma) mean FEV1 was 3126 ml, before challenge, while after methacholine challenge FEV1 was 2400ml. Following 1-year of sodium nedocromil administration the FEV1 was 2601ml (P<0.05). Before treatment, the mean fall in FEV1, following methacholine challenge, was 23.67% while following a 1-year-long sodium nedocromil administration this value reduced to 15.70% (P<0.05). Correspondingly, PC20 was 5.59 while after sodium nedocromil administration it increased to 11.66 (P<0.05). In Group II patients (intrinsic asthma) mean FEV1 was 2750 ml, before challenge, while after methacholine challenge FEV1 was 2066ml. Following 1-year of sodium nedocromil administration the FEV1 was 2223ml (P<0.05). Before treatment, the mean fall in FEV1, following methacholine challenge, was 27.65 % while following a 1-year-long sodium nedocromil administration this value reduced to 21.92 % (P<0.05). Correspondingly, PC20 was 5.91 while after sodium nedocromil administration it increased to 6.19 (P<0.05). The results suggest a positive effect of long-term sodium nedocromil administration in bronchial hyperreactivity for both groups of patients.

Thirty subjects (20 female and 10 male), all allergic to the mites D. Pteronyssinus and D. Farinae, participated in the present study which covered a period of four years. The subjects were randomly divided in two groups. Group I included 10 female and 5 male subjects, with an average age of 25.8 (+/− 3.5) years who received immunotherapy only. Group II had an average age of 31.5 (+/− 4) years and they received immunotherapy along with fluticazone propionate (1000mcg/day). The protocol for immunotherapy was the same for both groups. The basis FEV1 was determined for each subject of both Groups I and II and afterwards they were subjected to provocation tests of nebulized methacholine solution administered in consecutively larger concentrations until a drop in FEV1 >20 % (PC20), was observed. Three years later, when their therapy was completed, all subjects were subjected to the same provocation test and a significant reduction in bronchial hyperactivity was documented for both groups. In particular, for Group I, the percentage of change in FEV1 values was 27.25 +/- 5.23 % and PC20 5.11 +/− 2.64 mg/ml before immunotherapy, while after immunotherapy the same indicators were 22.22 +/- 7.08 % (P<0.05) and 6.85 +/− 4.03 mg/ml, (P<0.05) respectively. For Group II, the percentage of change in FEV1 values was 26.28 +/− 2.5 % and PC20 5.42 +/− 2.5 mg/ml before immunotherapy, while after immunotherapy the same indicators were 12.27 +/- 2.49 % (P<0.01)and 11.64 +/− 5.14 mg/ml, P<0.01 respectively. It is concluded that although significant reduction in hyperreactivity can be achieved through immunotherapy, the combination of immunotherapy with daily fluticazone propionate administration shows the most promising results.

Background. Extralevator abdominoperineal excision is associated with a high incidence of perineal wound complications. There is no uniform standard for choosing the method for pelvic floor reconstruction after extralevator abdominoperineal excision.The purpose of the study was to compare the results of extralevator abdominoperineal excisions of the rectum using various methods of perineal wound closure.Materials and Methods. Between 2014 and 2018, 120 patients underwent extralevator abdominoperineal excisions of the rectum using various options for closure of the pelvic floor. The patients were divided into 3 groups. Group I patients (n=64) underwent simple plasty of the peritoneal wound. Group II patients (n=43) underwent myoplasty using the gluteus maximus muscle. Group III patients (n=13) underwent myoplasty using the rectus abdominis muscle. The incidence of perineal wound complications in the early postoperative period was assessed.Results. The total number of perineal wound complications in Group I, II and III was 33 (51.5 %), 13 (30.2 %), and 6 (46.1 %), respectively. Grade IIIA-IIIB complications according to the Clavien-Dindo classification were observed in 25 % of Group I patients, in 18.6 % of Group II patients and in 7.7 % of Group II patients. Postoperative perineal wound complications occurred more often in Group I patients after simple plasty than in Group II and III patients after myoplasty (51.5 % versus 30.2 %). However, perineal wound complications were observed more often in Group III than in Group II (46.1 % versus 30.2 %, respectively). No significant differences in the frequency of complications between 3 groups were found.Conclusion. Using various options for closure of the pelvic floor after extralevator abdominoperineal excisions of the rectum, there was a tendency to reduction in the incidence of grade IIIA-IIIB perineal wound complications.

ABSTRACT Purpose To comparatively analyze the intrastromal MyoRing implantation with femtosecond laser (FL) using the standard and optimized technologies in the experiment and based on the long-term clinical-functional results of the patients with keratoconus (KC) at stages II and III. Materials and methods The experimental work was performed on 24 eyes of rabbits. All eyes were divided into six groups according to the method of operation. In the clinical part of the research, the surgical treatment of 70 patients (76 eyes) with KC at stages II and III was done. Depending on the technology of the operation, all patients were divided into two groups. Group I consisted of 29 patients (32 eyes) with KC, in which MyoRing implantation was performed according to the standard, group II consisted of 31 patients (32 eyes) with KC, in which MyoRing implantation was performed according to the optimized technology. Results Higher voltage was required for stretching samples of the second group in comparison with the third and the sixth group in comparison with the fifth group. In group I, during the period of 6 to 36 months the surgery reverses keratometry, corneal thickness above the MyoRing, and posterior corneal elevation. In group II, 12 months after surgery the clinical and functional parameters remained stable throughout the period of observation. Conclusion Greater reduction in corneal biomechanical stability was observed after formation of the intrastromal pocket in comparison with an intrastromal tunnel; a more pronounced increase in the strength characteristics of the cornea was observed after implantation of the ring in intrastromal pocket, compared with implantation intracorneal segments in intrastromal tunnel, and with increasing depth of intrastromal ring implantation. Application of optimized MyoRing implantation technology compared with standard allows more biomechanical parameters of the cornea to improve and reduce the risk of the ring protrusion.

The Relationship

Aim. To assess the relationship between the prolonged PR interval (≥200 ms) and the long-term survival of patients undergoing cardiac resynchronization therapy (CRT).Material and methods. A total of 85 patients (mean age — 55,1Ѓ}9,9 years; men — 81,2%) with NYHA class II-IV heart failure (HF) were examined. The mean follow-up was 34,0Ѓ}21,2 months. Patients with PR<200 ms (n=52) made up group I, with PR≥200 ms (n=33) — group II. Then the patients were divided into subgroups depending on the QRS duration: ≥150 ms (n=33 in group I and n=14 in group II, respectively) <150 ms (n=19 in group I and n=19 in group II, respectively).Results. In patients of group II, a history of myocardial infarction (MI) was more often registered (p=0,005), left ventricular ejection fraction (LVEF) was lower (p=0,032). In a multivariate analysis, MI (OR 3,217; CI 95% 1,188-8,712; p=0,022) and LVEF value (OR 0,869; CI 95% 0,780-0,968; p=0,011) had a significant relationship with the PR interval prolongation (≥200 ms). The survival of patients of group I was 59,6%, group II — 18,2% (Log-rank test p<0,001). According to Cox regression model, the initial left ventricle end-systolic volume (OR 1,012; 95% CI 1,006-1,017; p<0,001), inferior wall MI (OR 1,690; 95% CI 1,131-2,527; p=0,011) and PR interval ≥200 ms (OR 2,179; 95% CI 1,213–3,915; p=0,009) were associated with long-term mortality. In patients with PR≥200 ms, survival rate was low, regardless of the QRS duration (21,4% in patients with QRS≥150 ms, 15,8% in patients with QRS<150 ms; Log-rank test p=0,698) In patients with PR<200 ms, the survival rate of patients with QRS≥150 ms was 72,7%, and for patients with QRS<150 ms — 36,8% (Log-rank test p=0,031).Conclusion. In HF patients, PR interval prolongation (≥200 ms) is associated with long-term mortality increase. The highest survival rates were observed in patients with PR<200 ms and QRS≥150 ms. In patients with QRS≥150 ms, the presence of PR≥200 ms should be considered as an additional criterion for CRT.
