Closed Mitral Commissurotomy

Purpose: To evaluate long-term survival and valve-related complications as well as prognostic factors for mid- and long-term outcome after closed mitral commissurotomy, covering a follow-up period of 14 years. Material and Methods: Between 1989 and 2003, 36 patients (28 women and 8 men, mean age 28.8 6.1 years) underwent closed mitral commissurotomy at our institution. The majority of patients were in New York Heart Association (NYHA) functional class IIB, III, or IV. Indication for closed mitral commissurotomy was mitral stenosis. Closed mitral commissurotomy was undertaken with a Tubbs dilator in all cases. Median operating time was 2.5 hours 30 minutes. Results: After closed mitral commissurotomy, the mitral valve areas of these patients were increased substantially, from 0.9 to 2.11 cm2. No further operation after initial closed mitral commissurotomy was required in 86% of the patients (n = 31), and NYHA functional classification was improved in 94% (n = 34). Postoperative complications and operative mortality were not seen. Follow-up revealed restenosis in 8.5% (n = 3) of the patients, minimal mitral regurgitation in 22.2% (n = 8), and grade 3 mitral regurgitation in 5.5% (n = 2) patients. No early mortality occurred in closed mitral commissurotomy patients. Reoperation was essential for 5 patients following closed mitral commissurotomy; 2 procedures were open mitral commissurotomies and 3 were mitral valve replacements. No mortality occurred in these patients. Conclusions: The mitral valve area was significantly increased and the mean mitral valve gradient was reduced in patients after closed mitral commissurotomy. Closed mitral commissurotomy is a safe alternative to open mitral commissurotomy and balloon mitral commissurotomy in selected patients.

Stationary Heat Transfer

Based on the solution of the problem of non-stationary heat transfer during fluid motion in underground permeable layers, dependence was obtained to determine the operating time of the geothermal circulation system in the regime of constant and falling temperatures. It has been established that for a thickness of the layer H <4 m, the influence of heat influxes at = 0.99 and = 0.5 is practically the same, but for a thickness of the layer H> 5 m, the influence of heat inflows depends significantly on temperature. At a thickness of the permeable formation H> 20 m, the heat transfer at = 0.99 has virtually no effect on the thermal processes in the permeable formation, but at = 0.5 the heat influx, depending on the speed of movement, can be from 50 to 90%. Only at H> 50 m, the effect of heat influx significantly decreases and amounts, depending on the filtration rate, from 50 to 10%. The thermal effect of the rock mass with its thickness of more than 10 m, the distance between the discharge circuit and operation, as well as the speed of the coolant have almost no effect on the determination of the operating time of the GCS in constant temperature mode. During operation of the GCS at a dimensionless coolant temperature = 0.5, the velocity of the coolant is significant. With an increase in the speed of the coolant in two times, the error changes by 1.5 times.

Dental surgeons need in-depth knowledge of the bone tissue status and gingival morphology of atrophic maxillae. The aim of this study is to describe preoperative virtual planning of placement of five implants and to compare the plan with the actual surgical results. Three-dimensional planning of rehabilitation using software programs enables surgical guides to be specially designed for the implant site and manufactured using 3D printing. A patient with five teeth missing was selected for this study. The patient’s maxillary region was scanned with CBCT and a cast model was produced. After virtual planning using ImplantViewer, five implants were placed using a printed surgical guide. Two weeks after the surgical procedure, the patient underwent another CBCT scan of the maxilla. Statistically significant differences were detected between the virtually planned positions and the actual positions of the implants, with a mean deviation of 0.36 mm in the cervical region and 0.7 mm in the apical region. The surgical technique used enables more accurate procedures when compared to the conventional technique. Implants can be better positioned, with a high level of predictability, reducing both operating time and patient discomfort.

Представлены клинические результаты хирургического лечения доброкачественной гиперплазии предстательной железы (ДГПЖ) объемом до 100 см3 методом биполярной трансуретральной резекции простаты (БТУР -74 пациента) в сравнении с открытой чреспузырной простатэктомией (ОПЭ - 96 пациентов), ранее применявшейся для подобных клинических случаев в урологической клинике "Железнодорожной больницы" г. Волгоград. При статистически равном операционном времени обоих хирургических методов для БТУР отмечено существенное снижение интраоперационной кровопотери, сроков послеоперационной катетеризации и пребывания в стационаре, минимальная частота геморрагических и инфекционно-воспалительных осложнений. Наблюдение за урологическим статусом пациентов в течение первого послеоперационного года показало одинаковую клиническую эффективность сравниваемых хирургических методов. Значительное снижение объема кровопотери в ходе операции БТУР можно считать большим достижением, поскольку улучшение видимости в зоне хирургического вмешательства позволяет оптимизировать гемостаз, предотвратить массивные кровотечения как во время, так и после операции, сократить сроки послеоперационной катетеризации мочевого пузыря, что в свою очередь, снижает частоту развития инфекционно-воспалительных осложнений. Более быстрое восстановление пациентов после эндоскопических операций имеет медико-социальное и экономическое значение, поскольку минимальное количество послеоперационных осложнений и сокращение сроков госпитализации позволяет существенно снизить затраты на лечение и быстрее нормализовать качество жизни пациентов. Полученные результаты демонстрируют перспективность внедрения биполярных методов эндоскопических операций для лечения ДГПЖ в хирургическую практику урологических стационаров в целях повышения безопасности оперативного лечения и экономии затрат на госпитализацию. The clinical results of surgical treatment of benign prostatic hyperplasia (BPH) up to 100 cm3 by bipolar transurethral resection of the prostate (BTUR - 74 patients) in comparison with open transvesical prostatectomy (OPE - 96 patients), previously used for such clinical cases in the urological clinic "Railway hospital" in Volgograd are presented. With statistically equal operating time of both surgical methods, there was a significant decrease in intraoperative blood loss, the terms of postoperative catheterization and hospital stay, the minimum frequency of hemorrhagic and infectious-inflammatory complications. Observation of the urological status of patients during the first postoperative year showed the same clinical efficacy of the compared surgical methods. A significant reduction in the volume of blood loss during the operation, can be considered a great achievement, since the improvement of visibility in the area of surgical intervention allows to optimize the hemostasis, to prevent massive bleeding during and after surgery, to reduce the duration of postoperative bladder catheterization, which, in turn, reduces the incidence of infectious-inflammatory complications. Faster recovery of patients after endoscopic surgery of medical,social and economic importance, as the minimum number of postoperative complications and reduction of hospitalization can significantly reduce the cost of treatment and quickly normalize the quality of life of patients. The results demonstrate the prospects of the introduction of bipolar methods of endoscopic surgery for the treatment of BPH in the surgical practice of urological hospitals in order to improve the safety of surgical treatment and save costs for hospitalization.

Endoscopic Tympanoplasty

Tympanoplasty is one of the most performed procedures in ENT. The aggressiveness of its microscopic approach has led otologists to adopt the endoscopic approach as a less invasive alternative. The purpose of this work is to appreciate the advantages and disadvantages of this surgical technique. We conducted a prospective descriptive cross-sectional study on 20 interventions within the ENT department of August the 20th 1953 Hospital of Casablanca from April 2019 to June 2019. The average age of operated patients was 36.3 years. Perforations were unilateral in (71%) of the cases with a predominance of the anterior (29%) and subtotal (36%) locations. The tympanoplasties were performed by 3 different senior otologic surgeons, and were left in (57%). The mean operating time was (59.5 min) and the mean anesthesia duration was 75.1 min. Intraoperative vision allowed us to fully visualize the margins of all perforations (100%) and anatomical structures of the middle ear in almost all interventions. The first procedures carried out were filled with difficulties whose management of intraoperative bleeding was the main one in (42.8%) of the cases. (57%) procedures were described as easy. No complication was detected intraoperatively or immediately postoperatively. Endoscopic tympanoplasty has several advantages, including: Minimally invasive approach to the middle ear; panoramic perioperative vision; Gain of operating time; decrease in the duration of anesthesia; Valuable educational tool; postoperative comfort; Decrease in hospital stay and early return to daily activities; Better aesthetic rendering; cost and transportability. However, we also note a number of disadvantages of endoscopic tympanoplasty, particularly: performing the procedure with one hand; difficulty passing through the EAC; 2D vision that alters the perception of depth; management of intraoperative bleeding; fogging; learning curve.
