Blood loss,predictors of bleeding,transfusion practice and strategies of blood cell salvaging during liver transplantation

Blood loss during liver transplantation (OLTx) is a common consequence of pre-existing abnormalities of the hemostatic system,portal hypertension with multiple collateral vessels,portal vein thrombosis,previous abdominal surgery,splenomegaly,and poor "functional" recovery of the new liver.The intrinsic coagulopathic features of end stage cirrhosis along with surgical technical difficulties make transfusion-free liver transplantation a major challenge,and,despite the improvements in understanding of intraoperative coagulation profiles and strategies to control blood loss,the requirements for blood or blood products remains high.The impact of blood transfusion has been shown to be significant and independent of other well-known predictors of posttransplant-outcome.Negative effects on immunomodulation and an increased risk of postoperative complications and mortality have been repeatedly demonstrated.Isovolemic hemodilution,the extensive utilization of thromboelastogram and the use of autotransfusion devices are among the commonly adopted procedures to limit the amount of blood transfusion.The use of intraoperative blood salvage and autologous blood transfusion should still be considered an important method to reduce the need for allogenic blood and the associated complications.In this article we report on the common preoperative and intraoperative factors contributing to blood loss,intraoperative transfusion practices,anesthesiologic and surgical strategies to prevent blood loss,and on intraoperative blood salvaging techniques and autologous blood transfusion.Even though the advances in surgical technique and anesthetic management,as well as a better understanding of the risk factors,have resulted in a steady decrease in intraoperative bleeding,most patients still bleed extensively.Blood transfusion therapy is still a critical feature during OLTx and various studies have shown a large variability in the use of blood products among different centers and even among individual anesthesiologists within the same center.Unfortunately,despite the large number of OLTx performed each year,there is still paucity of large randomized,multicentre,and controlled studies which indicate how to prevent bleeding,the transfusion needs and thresholds,and the "evidence based" perioperative strategies to reduce the amount of transfusion.

Novel wreck salvaging method using curved rectangular pipe basing method:A case study of"Yangtze River EstuaryⅡ"ancient shipwreck salvage project

Shipwreck salvage is a risky,time-consuming,and expensive process.Although there are many sunken ships along coastlines and in the open seas,the salvage process of a sunken ship has rarely been reported.The integrated salvage of the"Yangtze River EstuaryⅡ"shipwreck used a novel method with 22 closely locked curved rectangular pipes to form a watertight base that wrapped the shipwreck inside.The basing was lifted out of the water using a powerful crane situated on an engineering ship.For the first time,the tunneling method was used in a shipwreck salvage project,significantly reducing the disturbance to the shipwreck and its stowage,thereby preserving the original state and integrity of the shipwreck to the greatest extent.In this study,the basic concepts of the salvage method and process are explained.Solutions to critical issues in the new salvage method are provided,including jacking force prediction and major considerations for the structural design of the salvage system.The design of the salvage system and salvage process of the"Yangtze River EstuaryⅡ"shipwreck are introduced.The monitored jacking force,pipe deformation,and observed water-tightness verified that the proposed method was effective and efficient.Other possible application scenarios for the proposed method are presented at the end.

Limb preservation with suprafascial and thin perforator flaps: salvaging osteomyelitis, Charcot collapse and critical limb ischemia

AIM: There are limited reports in the United States demonstrating outcomes of primarily thinned fasciocutaneous flaps in the setting of critical limb ischemia, Charcot collapse and osteomyelitis. We hope to determine patient and flap related outcomes in advanced lower extremity disease. Methods: The authors conducted a retrospective review of fasciocutaneous free flaps of variable thickness for lower extremity salvage. Osteomyelitis and non-osteomyelitis patients were compared according to our primary outcome measures: functional ambulation, bone healing and complications to flap and patient. Subgroups with critical limb ischemia, Charcot collapse and diabetic foot were analyzed separately. Results: Fifty-nine patients underwent free flap reconstruction: osteomyelitis (n = 20, 34%), Charcot collapse (n = 22, 37%), and/or critical limb ischemia (n = 12, 20%). All patients underwent anterolateral thigh flaps tailored for defect-specific thicknesses: 17 superthin, 25 suprafascial, 17 subfascial. There were no significant differences between groups in terms of partial and complete flap loss (P = 1.000 and P = 0.108). Ninety-one percent of patients were ambulatory at follow up. Eighty-tive percent of individuals with osteomyelitis cleared their infection demonstrating radiographic bone healing. Two patients developed recalcitrant deep space infections ultimately requiring amputation. Subgroup analysis did not show any differences in flap related complications within the diabetic Charcot population. In multivariate regression, preoperative revascularization was independently associated with failure of limb salvage. ;Conclusion: Primarily thinned perforator flaps performed well in the setting of lower extremity limb salvage, critical limbischemia, osteomyelitis, and the Charcot foot - expanding their role in the armamentarium for lower extremity care.

Clinical characteristics of testicular torsion and factors influencing testicular salvage in children:A 12-year study in tertiary center

BACKGROUND Testicular torsion is the most common acute scrotum worldwide and mainly occurs in children and adolescents.Studies have demonstrated that the duration of symptoms and torsion grade lead to different outcomes in children diagnosed with testicular torsion.AIM To predict the possibility of testicular salvage(TS)in patients with testicular torsion in a tertiary center.METHODS We reviewed the charts of 75 pediatric patients with acute testicular torsion during a 12-year period from November 2011 to July 2023 at the Suzhou Hospital of Anhui Medical University.Univariate and multivariate logistic regression analyses were used to determine independent predictors of testicular torsion.The data included clinical findings,physical examinations,laboratory data,color Doppler ultrasound findings,operating results,age,presenting institution status,and follow-up results.RESULTS Our study included 75 patients.TS was possible in 57.3%of all patients;testicular torsion occurred mostly in winter,and teenagers aged 11-15 years old accounted for 60%.Univariate logistic regression analyses revealed that younger age(P=0.09),body mass index(P=0.004),torsion angle(P=0.013),red blood cell count(P=0.03),neutrophil-to-lymphocyte ratio(P=0.009),and initial presenting institution(P<0.001)were associated with orchiectomy.In multivariate analysis,only the initial presenting institution predicted TS(P<0.05).CONCLUSION The initial presenting institution has a predictive value for predicting TS in patients with testicular torsion.Children with scrotal pain should be admitted to a tertiary hospital as soon as possible.

Indication and surgical approach for reconstruction with endoprosthesis in bone-associated soft tissue sarcomas:Appropriate case management is vital

It is important for surgeons performing sarcoma surgery to know that bone resection and tumor prosthesis applications in soft tissue sarcomas(STS)have unique features in terms of indication,surgical approach and follow-up,in terms of the management of these cases.Some STS are associated with bone and major neurovascular structures.Bone-associated STS are generally relatively large and relatively deep-seated.Additionally,the tendency for metastasis is high.In some cases,the decision about which structures to resect is difficult.These cases are often accompanied by poor oncological and surgical outcomes.Management of cases should be done by a multidisciplinary team in advanced centers specialized in this field.The surgical team must have sufficient knowledge and experience in the field of limb-sparing surgery.Preoperative evaluation and especially good planning of bone and soft tissue reconstruction are vital.

Expandable endoprostheses in skeletally immature patients:Where we are

Approximately 45 percent of malignant bone tumors are seen under the age of 16 and one of the important results of growth plate sacrification in patients with immature skeletons is limb inequality.Until the early 1990s,the treatment options for these patients were rotationplasty or amputation.Multimodal approaches that combine imaging,chemotherapy,and surgical techniques have enabled the development of limb-preserving methods with satisfactory results.In order to overcome inequality problems,expandable prostheses have been developed in the 1980s.Extendable endoprosthesis replacements have been improved over the years and are now an established and safe alternative.Noninvasive prostheses appear to be advantageous compared to minimally invasive expandable prostheses that require multiple surgical procedures,but the complication rate remains high.Therefore,although expandable prostheses are not the definitive answer to the treatment of bone sarcomas in skeletally immature children,they are still a suitable interim choice until full adulthood is achieved.Due to reported high complication rates,the procedures require significant experience and are recommended for use only in specialized cancer centers.

Salvage the Bones and The Not Yet: Environmental Crisis Writing of Post-Katrina Literature

After Hurricane Katrina in 2005,literary works related to such a crisis sprouted the southern America,which are known as Post-Katrina Literature.This thesis,taking Salvage the Bones and The Not Yet as examples,scrutinizes how writers respond to the Post-Katrina environmental crisis in different ways.In Salvage the Bones,Jesmyn Ward employs a biographical genre to record the Katrina disaster,thereby,writings serving as a way of healing the psychic trauma of the writer herself;and in The Not Yet,Moira Crone presents a post-natural world by the employment of the Cli-Fi genre.Both writers enrich the tradition of Southern literature as well as American eco-literature.

Traumatic Lower Extremity Reconstruction in a Patient with Significant Vascular Comorbidities

Limb salvage after devastating traumatic injuries, cancer extirpation, and intrinsic disease is a complex decision-making process. Although several scoring and evaluation tools have been created to attempt to apply algorithmic decision-making to the process, thoughtful clinical decision-making remains the most important standard. When limb salvage is deemed appropriate, selection of a tissue flap for limb reconstruction is dependent on the size and location of the defect, patient comorbidities, nicotine dependence, mechanism of injury to the limb, patient lifestyle, occupation, and ambulatory status. This case involves a male trauma patient with significant comorbidities and a large lower extremity wound requiring multiple operations to attempt limb reconstruction with a rectus abdominis free flap. This patient’s complex injury and comorbidities made the risk of flap failure high, illustrating that the importance of patient- and case-specific factors cannot be overstated when planning for a limb reconstruction. This extreme resort of limb reconstruction, where limb loss is the only other option and a likely consequence of even heroic efforts, is aptly called “limb salvage”.

Alternative technique to save ischemic bowel segment in management of neonatal short bowel syndrome: A case report

BACKGROUND Congenital short bowel syndrome(SBS)associated with malrotation,gut volvulus and jejuno-ileal atresia is a very rare condition.It is a severe challenge for surgeons to preserve residual ischemic bowel segment in the management of short bowel syndrome,especially in neonates.CASE SUMMARY We report a newborn baby with gut malrotation associated with jejuno-ileal atresia,congenital SBS and jejunal volvulus.Hematemesis and abdominal distention were noted.At laparotomy,malrotation associated with jejuno-ileal atresia,congenital SBS and jenunal volvulus was confirmed.The total length of the small bowel was 63 cm with proximal jejunal bowel segment measuring 38 cm,including 18 cm necrotic segment below the Treitz’s ligament and 20 cm severe ischemic segment.The distal part of the small bowel was 25 cm in length and only about 0.8 cm in diameter.Ladd’s procedure,necrotic segment resection and end-to-back duodeno-ileal anastomosis were performed.The residual severe ischemic jejunum was preserved with single proximal stoma and distal end closure.Three months later,to restore the continuity of the isolated gut segment,end-to-end duodeno-jejunal and jejuno-ileal anastomosis was performed.The entire functional small bowel length increased to 80 cm.Intravenous fluid therapy and parenteral nutrition were discontinued on the 10th day postoperatively.Twelve months later,her body weight was 9.5 kg.CONCLUSION Isolation of severe ischemic bowel segment and staged anastomosis to restore the gut continuity for infants with SBS are safe and feasible.

Striding On The Waste Land

Living in modern world,the civilization is highly developed.Human beings are living an unprecedented prosperous life,but the spiritual waste land is still invisibly existed.Highly mechanism alienates people even more serious than what it is in the Waste Land.So the fighting against the Waste land to salvage it as well as ourselves is endless and circulatory.The Waste Land thus is not decaying and hopeless,but natural and common as at any time.Moreover,the new conditions of life required“a new discipline of suffering”.So we should do as the poet does:accept reality,positively indulge in it to feel and experience fully,to suffer it.Then we will feel that The Waste Land brings us not a melancholy mood,but a positive encouragement for the salvage of ourselves.

Transfusion and coagulation management in liver transplantation

There is wide variation in the management of coagulation and blood transfusion practice in liver transplantation. The use of blood products intraoperatively is declining and transfusion free transplantations take place ever more frequently. Allogenic blood products have been shown to increase morbidity and mortality. Primary haemostasis, coagulation and fibrinolysis are altered by liver disease. This, combined with intraoperative disturbances of coagulation, increases the risk of bleeding. Meanwhile, the rebalancing of coagulation homeostasis can put patients at risk of hypercoagulability and thrombosis. The application of the principles of patient blood management to transplantation can reduce the risk of transfusion. This includes: preoperative recognition and treatment of anaemia, reduction of perioperative blood loss and the use of restrictive haemoglobin based transfusion triggers. The use of point of care coagulation monitoring using whole blood viscoelastic testing provides a picture of the complete coagulation process by which to guide and direct coagulation management. Pharmacological methods to reduce blood loss include the use of anti-fibrinolytic drugs to reduce fibrinolysis, and rarely, the use of recombinant factor VIIa. Factor concentrates are increasingly used; fibrinogen concentrates to improve clot strength and stability, and prothrombin complex concentrates to improve thrombin generation. Non-pharmacological methods to reduce blood loss include surgical utilisation of the piggyback technique and maintenance of a low central venous pressure. The use of intraoperative cell salvage and normovolaemic haemodilution reduces allogenic blood transfusion. Further research into methods of decreasing blood loss and alternatives to blood transfusion remains necessary to continue to improve outcomes after transplantation.

“Rescue” regimens after Helicobacter pylori treatment failure

Helicobacter pylori (H pylori) infection is the main cause of gastritis, gastroduodenal ulcer disease, and gastric cancer. After more than 20 years of experience in H pylori treatment, in my opinion, the ideal regimen to treat this infection is still to be found. Currently, apart from having to know first-line eradication regimens well, we must also be prepared to face treatment failures. Therefore, in designing a treatment strategy we should not focus on the results of primary therapy alone, but also on the final (overall) eradication rate. The choice of a "rescue" treatment depends on which treatment is used initially. If a clarithromycin- based regimen was used initially, a subsequent metronidazole-based treatment (quadruple therapy) may be used afterwards, and then a levofloxacin- based combination would be a third "rescue" option. Alternatively, it has recently been suggested that levofloxacin-based rescue therapy constitutes an encouraging second-line strategy, representing an alternative to quadruple therapy in patients with previous PPI-clarithromycin-amoxicillin failure, with the advantage of efficacy, simplicity and safety. In this case, a quadruple regimen may be reserved as a third-line rescue option. Finally, rifabutin-based rescue therapy constitutes an encouraging empirical fourth- line strategy after multiple previous eradication failures with key antibiotics such as amoxicillin, clarithromycin, metronidazole, tetracycline, and levofloxacin. Even after two consecutive failures, several studies have demonstrated that H pylori eradication can finally be achieved in almost all patients if several rescue therapies are consecutively given. Therefore, the attitude in H pylori eradication therapy failure, evenafter two or more unsuccessful attempts, should be to fight and not to surrender.

Effect of autotransfusion system on tumor recurrence and survival in hepatocellular carcinoma patients

AIM:To investigate the therapeutic efficacy and safety of continuous autotransfusion system(CATS) during liver transplantation of hepatocellular carcinoma patients.METHODS:Eighty-three hepatocellular carcinoma(HCC) patients who underwent liver transplantation with intraoperative CATS(n = 24,CATS group) and without(n = 59,non-CATS group) between April 2006 and November 2011 at the Liver Transplant Institute of Inonu University were analyzed retrospectively.Postoperative HCC recurrence was monitored by measuring alpha-fetoprotein(AFP) levels at 3-mo intervals and performing imaging analysis by thoracoabdominal multidetector computed tomography at 6-month intervals.Inter-group differences in recurrence and correlations between demographic,clinical,and pathological data were assessed by ANOVA and χ 2 tests.Overall and disease-free survivals were calculated by the univariate Kaplan-Meier method.RESULTS:Of the 83 liver transplanted HCC patients,89.2% were male and the overall mean age was 51.3 ± 8.9 years(range:18-69 years).The CATS and nonCATS groups showed no statistically significant differences in age,sex ratio,body mass index,underlying disease,donor type,graft-to-recipient weight ratio,Child-Pugh and Model for End-Stage Liver Disease scores,number of tumors,tumor size,AFP level,Milan and University of California San Francisco selection criteria,tumor differentiation,macrovascular invasion,median hospital stay,recurrence rate,recurrence site,or mortality rate.The mean follow-up time of the nonCATS group was 17.9 ± 12.8 mo,during which systemic metastasis and/or locoregional recurrence developed in 25.4% of the patients.The mean follow-up time for the CATS group was 25.8 ± 15.1 mo,during which systemic metastasis and/or locoregional recurrence was detected in 29.2% of the patients.There was no significant difference between the CATS and non-CATS groups in recurrence rate or site.Additionally,no significant differences existed between the groups in overall or disease-free survival.CONCLUSION:CATS is a safe procedure and may decrease the risk of tumor recurrence in HCC patients.

Precut sphincterotomy:A reliable salvage for difficult biliary cannulation

Even experienced endoscopists have 90% success in achieving deep biliary cannulation with standard methods. Biliary cannulation may become difficult in 10%-15% of patients with biliary obstruction and pre- cut (access) sphincterotomy is frequently chosen as a rescue treatment in these cases. Generally, precut sphincterotomy ensures a rate of 90%-100% success- ful deep biliary cannulation. The precut technique has been performed as either a fistulotomy with a needle knife sphincterotome or as a transpapillary septotomy with a standard sphincterotome. Both methods have similar efficacy and complication rates when adminis- tered to the proper patient. Although precut sphincter- otomy ensures over 90% success of biliary cannula- tion, it has been characterized as an independent risk factor for pancreatitis. The complications of the precut technique are not limited to pancreatitis. Two more important ones, bleeding and perforation, are also re- ported in some publications as being observed more commonly than during standard sphincterotomy. It is also reported that precut sphincterotomy increases morbidity when performed in patients without dilata- tion of their biliary tract. Nevertheless, precut sphinc- terotomy is a good alternative as a rescue method in the setting of a failed standard cannulation method. This paper discusses the technical details, timing, ef- ficacy and potential complications of precut sphincter- otomy.

Modified laparoscopic splenectomy and azygoportal disconnection combined with cell salvage is feasible and might reduce the need for blood transfusion

AIM: To investigate perioperative outcomes in patients undergoing modified laparoscopic splenectomy and azygoportal disconnection (MLSD) with intraoperative autologous cell salvage.

Conversion therapy and suitable timing for subsequent salvage surgery for initially unresectable hepatocellular carcinoma: What is new?

AIM To review the conversion therapy for initially unre-sectable hepatocellular carcinoma(HCC) patients and the suitable timing for subsequent salvage surgery. METHODS A Pub Med search was undertaken from 1987 to 2017 to identify articles using the keywords including "unresectable" "hepatocellular carcinoma", "hepate-ctomy", "conversion therapy", "resection", "salvage surgery" and "downstaging". Additional studies were investigated through a manual search of the references from the articles. The exclusion criteria were duplicates, case reports, case series, videos, contents unrelated to the topic, comments, and editorial essays. The main and widely used conversion therapies and the suitable timing for subsequent salvage surgery were discussed in detail. Two members of our group independently performed the literature search and data extraction. RESULTS Liver volume measurements [future liver remnant(FLR)/total liver volume or residual liver volume/bodyweight ratio] and function tests(scoring systems and liver stiffness) were often performed in order to justify whether patients were suitable candidates for surgery. Successful conversion therapy was usually defined as downstaging the tumor, increasing FLR and providing subsequent salvage surgery, without increasing com-plications, morbidity or mortality. The requirementsfor performing salvage surgery after transcatheter arterial chemoembolization were the achievement of a partial remission in radiology, the disappearance of the portal vein thrombosis, and the lack of extrahepatic metastasis. Patients with a standardized FLR(sF LR) > 20% were good candidates for surgery after portal vein embolization, while other predictive parameters like growth rate, kinetic growth rate were treated as an effective supplementary. There was probably not enough evidence to provide a standard operation time after associating liver partition and portal vein ligation for staged hepatectomy or yttrium-90 microsphere radioembolization. The indications of any combinations of conversion therapies and the subsequent salvage surgery time still need to be carefully and comprehen-sively evaluated. CONCLUSION Conversion therapy is recommended for the treatment of initially unresectable HCC, and the suitable subse-quent salvage surgery time should be reappraised and is closely related to its previous therapeutic effect.

Intraoperative cell salvage with autologous transfusion in liver transplantation

Liver transplant(LT) is the primary treatment for patients with end-stage liver disease. About 25000 LTs are performed annually in the world. The potential for intraoperative bleeding is quite variable. However, massive bleeding is common and requires blood transfusion. Allogeneic blood transfusion has an immunosuppressive effect and an impact on recipient survival, in addition to the risk of transmission of viral infections and transfusion errors, among others.Techniques to prevent excessive bleeding or to use autologous blood have been proposed to minimize the negative effects of allogeneic blood transfusion.Intraoperative reinfusion of autologous blood is possible through previous selfdonation or blood collected during the operation. However, LT does not normally allow autologous transfusion by prior self-donation. Hence, using autologous blood collected intraoperatively is the most feasible option. The use of intraoperative blood salvage autotransfusion(IBSA) minimizes the perioperative use of allogeneic blood, preventing negative transfusion effects without negatively impacting other clinical outcomes. The use of IBSA in patients with cancer is still a matter of debate due to the theoretical risk of reinfusion of tumor cells. However, studies have demonstrated the safety of IBSA in several surgical procedures, including LT for hepatocellular carcinoma. Considering the literature available to date, we can state that IBSA should be routinely used in LT, both in patients with cancer and in patients with benign diseases.

Salvage liver transplantation in the treatment of hepatocellular carcinoma:A Meta-analysis

AIM:To evaluate survival and recurrence after salvage liver transplantation(SLT) for the treatment of hepatocellular carcinoma(HCC) compared with primary liver transplantation(PLT) using a meta-analysis.METHODS:Literature on SLT versus PLT for the treatment of HCC published between 1966 and July 2011 was retrieved.A meta-analysis was conducted to estimate pooled survival and disease-free rates.A fixed or random-effect model was established to collect the data.RESULTS:The differences in overall survival and disease-free survival rates at 1-year,3-year and 5-year survival rates were not statistically significant between SLT group and PLT group(P > 0.05).After stratifying the various studies by donor source and Milan criteria,we found that:(1) Living donor liver transplantation recipients had significantly higher 1-year survival rate,lower 3-year and 5-year survival rates compared with deceased-donor liver transplantation(DDLT) recipients.And in DDLT recipients they had better 1-year and 5-year disease-free survival rate in SLT group;and(2) No difference was seen in 1-year,3-year and 5-year survival rates between two groups who beyond Milan criteria at the time of liver transplantation.CONCLUSION:SLT can be effectively performed for patients with recurrence or deterioration of liver function after hepatectomy for HCC.It does not increase the perioperative mortality and has a similar long-term survival rates compared to PLT.
