Minimize Blood Loss

Abstract Background Hepatectomy in children deserves exhaustive preoperative and intraoperative tools to define the anatomy, minimize blood loss, and confirm adequacy of liver tissue left. The aim of this study is to report our experience in surgical management of liver tumors. Results All liver resections performed in Ain-Shams University Hospital, by the same team, between July 2013 and June 2018 were retrospectively reviewed. Data related to basic demographics, indication for resection, methods of parenchymal resection, blood loss, hospital stay, morbidity, and mortality was collected. The study included 27 patients who underwent different types of hepatectomies. There was a male predominance. Age ranged from 6 months to 13 years. Weight ranged from 5.7 to 33.7 kg. Total operative time ranged from 68 to 322 min, while resection time ranged from 34 to 144 min. Blood loss ranged from 53 to 259 ml. Surgical morbidities included five patients with minor biliary leak, three patients had surgical site infection, and one patient had torsion of the remnant liver necessitating repositioning. Recurrence of the mass was faced in three patients with hepatoblastoma. There were two mortalities; one occurred as a sequela of massive intraoperative bleeding and the other took place due to postoperative hepatic insufficiency. Conclusion For a safe hepatectomy, thorough familiarity of the hepatic segmental anatomy together with the various techniques for parenchymal resection and vascular control is fundamental. Complications such as biliary leak and torsion of remnant can be easily avoided by simple measures.

Abstract Central bisegmentectomy (CBS) of the liver is an en bloc hepatic resection of Couiaud segments 4, 5, and 8. The indications for CBS include benign and malignant tumors occupying both the left medial and right anterior segments. However, CBS has rarely been reported. Here, we investigate CBS in patients with suboptimal liver function for whom an extended lobectomy is not an optimal solution. Each case was 1 of 8 patients who underwent CBS for hepatocellular carcinoma (HCC) or colorectal cancer liver metastasis (CRLM) at the Department of Surgery, Jikei University Hospital. Indications for CBS consisted of CRLM in 3 patients and HCC in 5 patients. The median duration of operation was 552 minutes, and median blood loss was 2263 g. No postoperative nor in-hospital mortalities occurred. In this study, 1-, 2-, and 3-year disease-free survival rates were 62.5%, 12.5%, and 12.5%, respectively, and 1-, 2-, and 3-year overall survival rates were 100%, 100%, and 85.7%, respectively. CBS is advocated for central liver tumors in patients with suboptimal liver function for whom extended lobectomy could result in less than optimal remnant liver volume and function.

Extracapsular Resection

Massive hemorrhage remains an important clinical problem in extracapsular resection of giant liver hemangiomas (GLHs), especially for those involving the proximal hepatic veins and/or inferior vena cava. Between July 2004 and March 2012, 87 patients with a complex GLH scheduled for surgical treatment were included in this study. All patients were underwent vascular preparation (Step 1), advanced hepatic artery clamping (Step 2), and stepwise vascular occlusion (Step 3). Intraoperative blood loss, blood transfusion volume, degree of ischemia–reperfusion injury, and postoperative complications were recorded. No patients required urgent vascular preparation to manage intraoperative bleeding. In total, 87, 64, and 21 patients had portal triad (PT), infra-hepatic inferior vena cava (IVC), and suprahepatic IVC preparation; and 17, 43, and 11 patients had PT, PTand suprahepatic IVC, and all three (PT, infra-, and suprahepatic IVC) occlusions. The PT, infrahepatic IVC, and SIVC occlusion times were 12.1 ± 3.7 minutes, 7.9 ± 2.4 minutes, and 3.2 ± 1.4 minutes, respectively. Mean blood loss was 291.9 ± 124.5 mL, and only four patients received blood transfusions. No patients had life-threatening complications or died (Clavien-Dindo Grade 4, 5). Compared with paralleled studies, this technique has an advantage to decrease the blood loss in less liver ischemia time. For complex GLH resections, the described step-by-step vascular control technique was efficacious and feasible for controlling intraoperative bleeding.

Objective: To study the various beliefs and problems regarding menstruation among adolescent girls living in rural border areas. Design- Prospective study. Setting- Pediatric outpatient clinic. Materials and methods- About 200 adolescent girls (11-19 years) living in rural border areas were enrolled for the study. These girls were asked about menarche, duration of the cycle, amount of blood loss and the various menstrual problems. They were also asked about the various beliefs and myths regarding menstruation. The girls having any illness affecting the menstrual cycle or those suffering from neuropsychiatric disorders were excluded from this study. Results- About 51% of the study population was in the age group 17-18 years. About 43.5% of girls attained menarche at the age of 10-12 years. About 51% of girls did not know about menstruation before menarche. Abdominal pain was the most common side effect seen in 41% of girls during menstruation. About 61% of girls considered themselves unclean during menstruation.  Twenty percent avoided schools, 20% avoided kitchen, 12% avoided temples while 10% stayed away from friends/ relatives. Only 33% of girls knew that menstruation stops temporarily after becoming pregnant. Twenty-two percent girls were using sanitary napkins while the rest used different types of clothes during the menstrual cycle. Conclusion- There is a dire need to educate girls regarding menstruation before menarche in the rural border areas. Every mother should discuss in a friendly way regarding various aspects of menstruation.

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.

AbstractTo evaluate potential factors associated with the risk of perioperative blood transfusion (PBT) with implications on length of hospital stay (LOHS) and major post-operative complications in patients who underwent robot-assisted radical prostatectomy (RARP) as a primary treatment for prostate cancer (PCa). In a period ranging from January 2013 to August 2019, 980 consecutive patients who underwent RARP were retrospectively evaluated. Clinical factors such as intraoperative blood loss were evaluated. The association of factors with the risk of PBT was investigated by statistical methods. Overall, PBT was necessary in 39 patients (4%) in whom four were intraoperatively. Positive surgical margins, operating time and intraoperative blood loss were associated with perioperative blood transfusion on univariate analysis. On multivariate analysis, the risk of PBT was predicted by intraoperative blood loss (odds ratio, OR 1.002; 95% CI 1.001–1.002; p < 0.0001), which was associated with prolonged operating time and elevated body mass index (BMI). PBT was associated with delayed LOHS and Clavien–Dindo complications > 2. In patients undergoing RARP as a primary treatment for PCa, the risk of PBT represented a rare event that was predicted by severe intraoperative bleeding, which was associated with increased BMI as well as with prolonged operating time. In patients who received a PBT, prolonged LOHS as well as an elevated risk of major Clavien–Dindo complications were seen.

Abstract Background A diagnostic sign on magnetic resonance imaging, suggestive of posterior extrauterine adhesion (PEUA), was identified in patients with placenta previa. However, the clinical features or surgical outcomes of patients with placenta previa and PEUA are unclear. Our study aimed to investigate the clinical characteristics of placenta previa with PEUA and determine whether an altered management strategy improved surgical outcomes. Methods This single institution retrospective study examined patients with placenta previa who underwent cesarean delivery between 2014 and 2019. In June 2017, we recognized that PEUA was associated with increased intraoperative bleeding; thus, we altered the management of patients with placenta previa and PEUA. To assess the relationship between changes in practice and surgical outcomes, a quasi-experimental method was used to examine the difference-in-difference before (pre group) and after (post group) the changes. Surgical management was modified as follows: (i) minimization of uterine exteriorization and adhesion detachment during cesarean delivery and (ii) use of Nelaton catheters for guiding cervical passage during Bakri balloon insertion. To account for patient characteristics, propensity score matching and multivariate regression analyses were performed. Results The study cohort (n = 141) comprised of 24 patients with placenta previa and PEUA (PEUA group) and 117 non-PEUA patients (control group). The PEUA patients were further categorized into the pre (n = 12) and post groups (n = 12) based on the changes in surgical management. Total placenta previa and posterior placentas were more likely in the PEUA group than in the control group (66.7% versus 42.7% [P = 0.04] and 95.8% versus 63.2% [P < 0.01], respectively). After propensity score matching (n = 72), intraoperative blood loss was significantly higher in the PEUA group (n = 24) than in the control group (n = 48) (1515 mL versus 870 mL, P < 0.01). Multivariate regression analysis revealed that PEUA was a significant risk factor for intraoperative bleeding before changes were implemented in practice (t = 2.46, P = 0.02). Intraoperative blood loss in the post group was successfully reduced, as opposed to in the pre group (1180 mL versus 1827 mL, P = 0.04). Conclusions PEUA was associated with total placenta previa, posterior placenta, and increased intraoperative bleeding in patients with placenta previa. Our altered management could reduce the intraoperative blood loss.

Background Previous studies and meta analyses have led to incongruent and incomplete results respectively when total intravenous anesthesia (TIVA) and inhalational anesthesia (IA) are compared in endoscopic sinus surgeries in regards to intraoperative bleeding and visibility. Objective To perform a more comprehensive meta-analysis on randomized controlled trial (RCTs) comparing TIVA with IA in endoscopic sinus surgery to evaluate their effects on intraoperative bleeding and visibility. Methods A systematic review and meta-analysis of studies comparing TIVA and IA in endoscopic sinus surgery for chronic rhinosinusitis was completed in May 2020. Utilizing databases, articles were systematically screened for analysis and 19 studies met our inclusion criteria. The primary outcome included intraoperative visibility scores combining Boezaart, Wormald and Visual Analogue Scale (VAS). Secondary outcomes included rate of blood loss (mL/kg/min), estimated total blood loss (mL), Boezaart, Wormald scores, VAS, heart rate, and mean arterial pressure (MAP). Results 19 RCTs with 1,010 patients were analyzed. TIVA had a significantly lower intraoperative bleeding score indicating better endoscopic visibility (Boezaart, VAS, and Wormald) than IA (−0.514, p = 0.020). IA had a significantly higher average rate of blood loss than TIVA by 0.563 mL/kg/min (p = 0.016). Estimated total blood loss was significantly lower in TIVA than IA (−0.853 mL, p = 0.002). There were no significant differences between TIVA and IA in the mean heart rate (−0.225, p = 0.63) and MAP values (−0.126, p = 0.634). The subgroup analyses revealed no significant difference between TIVA and IA when remifentanil was not utilized and whenever desflurane was the IA agent. Conclusion TIVA seemed to have superior intraoperative visibility scores and blood loss during endoscopic sinus surgery when compared to IA. However, the results are not consistent when stratifying the results based on the use of remifentanil and different inhaled anesthetics. Therefore, the conclusion cannot be made that one approach is superior to the other.

Abstract Background Non neoplastic GI lesions in pediatrics are variable and differ in types and prevalence among each pediatric age group. Helicobacter pylori is an important pathogen that can cause gastritis and peptic ulcers in adults as well as in children. Celiac disease is a gluten-dependent autoimmune disorder which affects individuals having genetic susceptibility. Eosinophilic gastrointestinal diseases are disorders that primarily affect the gastrointestinal tract with eosinophil-rich inflammation in the absence of known causes for eosinophilia. Inflammatory bowel disease (IBD) is a chronic inflammatory disorder, mainly affecting the gastrointestinal tract with extraintestinal manifestations and associated immune disorders. It seems that it is one of the most common gastrointestinal diseases affecting children in the developed countries. Aim of the work To study different types of paediatric non neoplastic gastrointestinal lesions from gastrointestinal endoscopic biopsies received at the Pathology Department in Ain Shams University hospital during a period of 2 years (2017-2018), and to correlate them with the clinicopathological presentations and endoscopic findings. Patients and Methods A cross sectional study was conducted on all pediatric gastrointestinal biopsies received at Pathology Department in Ain Shams University Hospital during the period of two years (2017- 2018). Only cases with information for all the covariates (n = 580) were selected and the results were statistically analyzed. Results Total 580 pediatric cases were enrolled according to inclusion criteria. Nonspecific gastrointestinal inflammation represented (47.1%), Helicobacter pylori associated gastrointestinal inflammation represented (43.5%), Eosinophilic gastrointestinal disease represented (3.8%), Inflammatory bowel disease (IBD) represented (3.7%), Celiac disease represented (1.9%). Conclusion This is the first study conducted in Ain Shams University Hospitals to assess the different types of pediatric non neoplastic gastrointestinal lesions received with clinicopathological and endoscopic correlation. The most common pediatric non neoplastic GI lesion is Helicobacter pylori infection. The diagnosis of pediatric non neoplastic GI disorder necessitates interdepartmental teamwork between GI pediatricians and pathologists.
