Objective To investigate the efficacy and safety of transurethral holmium laser resection (THOLR) and transurethral electrocision (TUR) combined with intravesical epirubicin within 24 hours postoperatively for treatment of non-muscular invasive bladder cancer. Methods A total of 218 consecutive patients who were newly diagnosed with bladder cancer were enrolled in this prospective study from July 2014 to December 2017. The patients were randomly divided into THOLR and TUR groups. All patients received intravesical epirubicin (30 mg dissolved in 5% glucose solution) within 24 hours postoperatively. The operation time, blood loss, rate of obturator reflex, hospitalization time, catheterization time, complications, and recurrence were analyzed. Results Operation, hospitalization, and catheterization times were significantly greater in the TUR group than in the THOLR group. The rates of blood loss and intraoperative obturator reflex were also significantly greater in the TUR group. There were no significant differences in complications, recurrence rate survival, or recurrence-free survival between the two groups, with the exception of bladder perforation rate. Conclusions THOLR and TUR combined with intravesical epirubicin within 24 hours postoperatively were both safe and effective for treatment of bladder tumor; however, patients who undergo THOLR might experience more rapid recovery.

Background: The greater omentum can limit abdominal inflammation and act as a protective cushion, but it is always involved in dissemination of gastric cancer. The purpose of this meta-analysis was to compare the survival and safety between total omentectomy and partial omentectomy for gastric cancer.Methods: Two investigators independently conducted a systematic search of PubMed, Embase, CNKI, and Cochrane Library ranging from January 2000 to November 2020. The pooled odds ratio (ORs) and weighted mean difference (WMD) with the 95% confidence interval (95% CI) were used to assess perioperative and survival parameters.Results: A total of 2,031 patients in 11 studies (574 patients in the partial omentectomy group and 1,457 patients in the total omentectomy group) were included. The results found shorter operation time (WMD = −25.584; P = 0.000) and less intraoperative blood loss (WMD = −47.301; P = 0.050) in the partial omentectomy group, compared to total omentectomy. There were no significant differences in terms of incidence of complications (OR = 0.770; P = 0.164), blood transfusions rates (OR = 0.269; P = 0.161), time to first flatus (WMD = 0.160; P = 0.345), hospital stay (WMD = −1.258; P = 0.087), and number of harvested lymph nodes (WMD = 1.265; P = 0.662). For the disease-free survival (OR = 0.80; P = 0.381) and overall survival, there were no statistical differences between the two procedures.Conclusions: The partial omentectomy could reduce operation time and trended to decrease intraoperative blood loss. And the survival in patients with partial omentectomy seemed to be comparable to that of patients with total omentectomy.

Background. Radical cystectomy uses laparoscopic and robotic approaches along with the open ones.Objective: to study immediate results of robot-assisted radical cystectomy with intracorporeal orthotopic cystoplasty.Materials and methods. Robot-assisted radical cystectomy with intracorporeal orthotopic cystoplasty was performed in 15 patients (13 male, 2 female), aged 64–76 years. Fourteen patients had bladder cancer, 1 female – a postradiation bladder fistula and microcystis. T2 stage was detected in 8 (57.1 %) patients, T3 – in 6 (42.9 %). After the operation we evaluated operation time, blood loss volume, hospital stay, functional and oncological results.Results. Average operation time was 380 (320–560) minutes, blood loss volume – 80–200 ml, blood transfusion was not performed. Early complications (up to 30 days) were observed in 7 patients (46.7 %), late ones (90‑days) – in 6 (40.0 %). There were no cases of intestinal obstruction. Patients with ureteral-intestinal (n = 2) and reservoir-urethral (n = 1) anastomosis failure underwent percutaneous renal drainage. One patient died of acute myocardial infarction. Daytime continence was 80.0 %, nocturnal – 53.3 %. One patient died of disease progression within 7.6 observation months.Conclusion. Robot-assisted radical cystectomy with intracorporeal urine diversion is a modern and minimally invasive method for patients with muscle-invasive bladder cancer. More experience in this field will allow to reduce surgery time and number of complications.

Цель исследования - изучение способности фибрин-мономера предупреждать тяжелую интраоперационную кровопотерю, ассоциированную с введением нефракционированного гепарина, при дозированной травме печени. Методика. На кроликах «Шиншилла» индуцировали гипокоагуляцию нефракционированным гепарином (150 ед/кг). Профилактику интраоперационных кровотечений осуществляли внутривенным введением фибрин-мономера (0,25 мг/кг) за 1 ч до травмы или протамина сульфата (1,5 мг/кг) за 10 мин до травмы. После нанесения стандартной травмы печени оценивали объем (в % ОЦК) и темп (мг/с) кровопотери. Анализировали число тромбоцитов, активированное парциальное тромбопластиновое время, протромбиновое и тромбиновое время свертывания, уровень фибриногена и активность антитромбина III, параметры ротационной тромбоэластометрии крови. Результаты. Объем кровопотери в группах животных после в/в введения фибрин-мономера и протамина сульфата на фоне гепаринизации был, соответственно, в 5,1 и 4,0 раза меньше по сравнению с группой плацебо, получавшей тот же антикоагулянт. Вместе с тем, фибрин-мономер не влиял на параметры коагулограммы (отсутствие видимого гемостазиологического эффекта) и тромбоэластограммы, тогда как применение протамина сульфата в качестве антидота гепарина сопровождалось нормализацией данных тромбоэластометрии и коррекцией гипокоагуляционного сдвига по активированному парциальному тромбопластиновому времени, протромбиновому и тромбиновому времени. Заключение. Установлено, что фибрин-мономер (0,25 мг/кг) снижает посттравматическое кровотечение в условиях блокады свертывания крови гепарином без видимых признаков восстановления гемостатического равновесия. The research objective was to study the ability of fibrin monomer to prevent severe intraoperative blood loss associated with administration of unfractionated heparin in controlled liver injury. Methods. Hypocoagulation was induced in chinchilla rabbits with unfractionated heparin (150 U/kg). Intraoperative bleeding was prevented by administration of fibrin monomer (FM, 0.25 mg/kg, i.v.) one hour prior to the injury and of protamine sulfate (PS, 1.5 mg/kg, i.v.) 10 min prior to the injury. Following the liver injury, blood loss was assessed as percentage of circulating blood volume and the blood loss rate (mg/s). Platelet counts, aPTT, PT, TT, fibrinogen level, antithrombin III activity, and parameters of blood rotation thromboelastometry were analyzed. Results. The volume of blood loss was 5.1 times and 4.0 times less, respectively, after the FM and PS administration during heparinization compared to the placebo group treated with the same anticoagulant. However, FM affected neither coagulogram indexes (no visible hemostasiological effect) nor thromboelastogram while the use of PS as an antidote for heparin was associated with normalization of thromboelastometric data and correction of hypercoagulative changes in aPTT, PT, TT. Conclusion. FM at a dose of 0.25 mg/kg reduced severity of posttraumatic bleeding induced by heparin inhibition of coagulation with no visible signs of hemostatic balance recovery.

Abstract Background This present study is aimed to retrospectively assess the efficacy of three-dimensional (3D) printing assisted osteotomy guide plate in accurate osteotomy of adolescent cubitus varus deformity. Material and methods Twenty-five patients (15 males and 10 females) with the cubitus varus deformity from June 2014 to December 2017 were included in this study and were enrolled into the conventional group (n = 11) and 3D printing group (n = 14) according to the different surgical approaches. The operation time, intraoperative blood loss, osteotomy degrees, osteotomy end union time, and postoperative complications between the two groups were observed and recorded. Results Compared with the conventional group, the 3D printing group has the advantages of shorter operation time, less intraoperative blood loss, higher rate of excellent correction, and higher rate of the parents’ excellent satisfaction with appearance after deformity correction (P < 0.001, P < 0.001, P = 0.019, P = 0.023). Nevertheless, no significant difference was presented in postoperative carrying angle of the deformed side and total complication rate between the two groups (P = 0.626, P = 0.371). Conclusions The operation assisted by 3D printing osteotomy guide plate to correct the adolescent cubitus varus deformity is feasible and effective, which might be an optional approach to promote the accurate osteotomy and optimize the efficacy.

Study Design: Systematic review and meta-analysis. Objectives: Arthrodesis has been a valid treatment option for spinal diseases, including spondylolisthesis and lumbar spinal stenosis. Posterolateral and posterior lumbar interbody fusion are amongst the most used fusion techniques. Previous reports comparing both methods have been contradictory. Thus, we conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to establish substantial evidence on which fusion method would achieve better outcomes. Methods: Major databases including PubMed, Embase, Web of Science and CENTRAL were searched to identify studies comparing outcomes of interest between posterolateral fusion (PLF) and posterior lumbar interbody fusion (PLIF). We extracted data on clinical outcome, complication rate, revision rate, fusion rate, operation time, and blood loss. We calculated the mean differences (MDs) for continuous data with 95% confidence intervals (CIs) for each outcome and the odds ratio with 95% confidence intervals (CIs) for binary outcomes. P < 0.05 was considered significant. Results: We retrieved 8 studies meeting our inclusion criteria, with a total of 616 patients (308 PLF, 308 PLIF). The results of our analysis revealed that patients who underwent PLIF had significantly higher fusion rates. No statistically significant difference was identified in terms of clinical outcomes, complication rates, revision rates, operation time or blood loss. Conclusions: This systematic review and meta-analysis provide a comparison between PLF and PLIF based on RCTs. Although PLIF had higher fusion rates, both fusion methods achieve similar clinical outcomes with equal complication rate, revision rate, operation time and blood loss at 1-year minimum follow-up.
