    The list of surgical procedures of solid organ transplantations appears very interesting and colorful, even with overlap among techniques. Liver transplantation is a life-saving procedure in a majority of cases, the liver can be transplanted as a full or partial graft. The liver graft can be split for two recipients; it can also be reduced for a small recipient if splitting is not indicated. Kidney transplantation is the most common solid organ transplant procedure, the majority of kidney grafts come from brain-dead donors whereas the number of live donor transplants is increasing, also thanks to paired donation and blood group incompatible transplantation methods. The small bowel and multivisceral transplantation are rare procedures; they serve selected patients with short bowel syndrome, some patients with retroperitoneal tumors or with extensive visceral thrombosis. Solid organ transplants are well established treatment methods with good and proven outcomes. A majority of patients can return to a normal life after their transplants.

    The indication and timing of nephrectomy in patients with autosomal dominant polycystic kidney disease (ADPKD) remain controversial, especially in patients who are candidates to renal transplantation (RT). The main surgical options such as unilateral vs. bilateral nephrectomy, nephrectomy before vs. after RT, or simultaneous nephrectomy and transplantation, are herein discussed. Evidence acquisition of the best surgical management available for ADPKD in the context of kidney transplantation. Systematic literature review in PubMed from 1978 to 2013 was conducted. Articles selected included:randomized controlled trials and cohort studies. Furthermore, well designed ADPKD reviews were considered for this study. Laparoscopic nephrectomy in ADPKD is a safe procedure with an acceptable complication rate. Unilateral nephrectomy has advantages over the bilateral one regarding the perioperative complication rate. Although the timing of nephrectomy is controversial, it seems that simultaneous nephrectomy and renal transplantation does not increase surgical morbidity neither affect graft survival. Simultaneous nephrectomy and RT appears to be an acceptable alternative to conventional two-stage procedure without any increased morbidity, in the context of ADPKD. Furthermore, laparoscopic nephrectomy performed in experienced centres is a safe alternative to conventional approach. Copyright © 2013 AEU. Published by Elsevier Espana. All rights reserved.

    Meniscus allograft transplantation has been performed over the past 25 years to relieve knee pain and improve knee function in patients with an irreparable meniscus injury. The efficacy and safety of meniscus allograft transplantation have been established in numerous experimental and clinical researches. However, there is a lack of reviews to aid radiologists who are routinely interpreting images and evaluating the outcome of the procedures, and also meniscus allograft transplantation is not widely performed in most hospitals. This review focuses on the indications of the procedure, the different surgical techniques used for meniscus allograft transplantation according to the involvement of the lateral and medial meniscus, and the associated procedures. The postoperative radiological findings and surgical complications of the meniscus allograft transplantation are also described in detail. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Background: Liver transplantation is well established worldwide as an effective treatment for end-stage liver disease in children. Acceptance in India has been slow because of considerations of cost, infections, inability to support long-term care, and non-availability of expertise. Aim: This study was designed to report our experience with pediatric liver transplantation. Materials and Methods: Twenty-eight children underwent liver transplantation. Results: Biliary atresia was the commonest indication (n = 15 followed by metabolic liver disease. Twenty-six children had living donor transplants, mothers being the donors in a majority of these. Common surgical complications included bile leaks (n = 3 and vascular problems (n = 6. Common medical complications included infections, acute rejection, and renal failure. Overall, patient survival was 71%, while that for the last 14 cases was 92%. All survivors are doing well, have caught up with physical and developmental milestones and are engaged in age appropriate activities. Conclusions: The study demonstrates the feasibility of a successful pediatric liver transplant program in our country.

    Biliary strictures are the most common biliary tract complication after liver transplantation. There are scarce data on the results of hepaticojejunostomy (HJ) in the management of biliary complications after orthotopic liver transplantation (OLT). Thus, the role of surgery in this setting remains to be established. The aim of this study was to evaluate the results of surgical treatment of patients with biliary complications at our institution. We reviewed 1000 consecutive liver transplantations performed at our institution from 1984 to 2007. We used a prospectively recorded database to identify patients who underwent HJ to treat any biliary tract complication. Overall, 62 patients (6.2%) underwent HJ, 40 for an anastomotic and 7 for a non-anastomotic stricture as well as 15 for biliary leaks. Postoperative morbidity was 16%, and postoperative mortality 1.6%. There were 7 cases of anastomotic stenosis (11.3%). Four patients (5%) required retransplantation. HJ is a safe procedure to manage biliary complications after OLT. It may be the first treatment choice especially for cases with anastomotic strictures. Copyright © 2012 Elsevier Inc.

    Pre-existing chronic liver diseases and the complexity of the transplant surgery procedures lead to a greater risk of further surgery in transplanted patients compared to the general population. The aim of this monocentric retrospective cohort study was to assess the epidemiology of surgical complications in liver transplanted patients who require further surgical procedures and to characterize their post-operative risk of complications to enhance their medical care. From January 1997 to December 2011, 1211 patients underwent orthotropic liver transplantation in our center. A retrospective analysis of prospectively collected data was performed considering patients who underwent surgical procedures more than three months after transplantation. We recorded liver transplantation technique, type of surgery, post-operative complications, time since the liver transplant and immunosuppressive regimens. Among these, 161 patients (15%) underwent a further 183 surgical procedures for conditions both related and unrelated to the transplant. The most common surgical procedure was for an incisional hernia repair (n = 101), followed by bilioenteric anastomosis (n = 44), intestinal surgery (n = 23), liver surgery (n = 8) and other surgical procedures (n = 7). Emergency surgery was required in 19 procedures (10%), while 162 procedures (90%) were performed electively. Post-operative mortality and morbidity were 1% and 30%, respectively. According to the Dindo-Clavien classification, the most common grade of morbidity was grade III (46%), followed by grade II (40%). Surgical procedures on liver transplanted patients are associated with a significantly high risk of complications, irrespective of the time elapsed since transplantation.

    With an increasing number of liver transplantation (LT) and an enhanced overall survival, LT recipients are more likely to be admitted in emergency departments of general hospitals. Yet, in LT recipients, common but also benign symptoms may reveal a LT-related (or not) severe condition. To improve management of LT recipients by emergency physicians and general surgeons and potentially improve long-term outcomes, a clinical review was performed. Overall, CT scan and blood tests should be systematically performed. Immunosuppressive side effects should be excluded using blood tests. LT-related complications are more likely to occur during the first three months after LT, including mainly bile leak, arterial aneurysm, and pseudoaneurysm. Patients should be referred in emergency to tertiary centers. Non-LT-related complications and common abdominal conditions may also be diagnosed in LT recipients. Except in case of diffuse peritonitis or in hemodynamically unstable patients when surgical procedure should be performed, most conditions should be reassessed regarding the immunosuppressive treatment and the adhesive abdominal cavity. © 2017 John Wiley & Sons A/S.

    To evaluate whether surgical complications after kidney transplantation correlate with surgeon's experience and whether individual surgeons' complication rates improve during their learning process. Retrospective analysis: A generalized linear mixed-effects model was used to identify risk factors for surgical complications. Plots of cumulative sums of complications were used to evaluate the individual surgeons' performance. Single-center experience of a teaching hospital in Switzerland. Consecutive kidney transplant recipients operated from 1962 until 2003. A total of 1496 kidney transplants were analyzed; 73% were from deceased donors and 27% from living donors. At least 1 surgical complication occurred in 352 patients (24%). Male gender (odds ratio [OR] = 1.35, 95% CI: 1.04-1.74), donor's age (OR = 1.14, 95% CI: 1.06-1.24 per decade increment), and third or fourth vs. first or second transplant in a recipient (OR = 2.90, 95% CI: 1.02-8.24) were significantly associated with surgical complications. The surgeon's transplant experience was not found to be associated with surgical complications. Even surgeons with an experience of less than 10 kidney transplants did not have higher complication rates, 30-day mortality, or 1-year graft survival. Individual surgeons' complication rates analyzed by cumulative sum plots did not improve with increasing experience. We present the largest single-center study on surgical complications after kidney transplantation, with unique data on the surgeon's experience for every single procedure. We found no evidence for a learning curve during training for kidney transplantation. We conclude that carefully selected experienced general and vascular surgeons can achieve good results in kidney transplantation after a relatively short training period.

    The potential for integrating real-time surgical video and state-of-the art animation techniques has not been widely applied to surgical education. This paper describes the use of new technology for creating videos of liver, pancreas and transplant surgery, annotating them with 3D animations, resulting in a freely-accessible online resource: The Toronto Video Atlas of Liver, Pancreas and Transplant Surgery ( http://tvasurg.ca ). The atlas complements the teaching provided to trainees in the operating room, and the techniques described in this study can be readily adapted by other surgical training programmes.

    Liver transplant is the treatment of choice for end-stage liver disease. Management of transplant patients requires a multidisciplinary approach, with radiologists playing a key role in identifying complications in both symptomatic and asymptomatic patients. Ultrasonography remains the investigation of choice for the initial evaluation of symptomatic patients. Depending on the clinical situation, further evaluation with CT, MRI, or biopsy may be performed or clinical and imaging surveillance may be continued. This article discusses the various normal and abnormal imaging presentations of liver transplant patients, including various acute and chronic complications, and their management.

    Full Text Available Introduction. Due to the ever-present lack of kidney transplant grafts, more and more organs obtained from the so-called “marginal donors” group are accepted, which can provide suboptimal effect of transplantation, depending on their characteristics and/or implantation techniques. Case report. We presented a case with successful variation of kidney position with modified approach of kidney transplantation from an infant to an adult female patient with normal postoperative recovery. Urethral anastomosis was performed without antireflux procedure and this has not led to the development of reflux disease at an early stage. Conclusion. The position of a pair of kidneys proved to be satisfactory despite the growth of the kidney to the expected size and relatively small pelvis. There were no problems with venous stasis and kidney function from the very beginning was good.

    Full Text Available Introduction. Encapsulating peritoneal sclerosis (EPS is a clinical syndrome of progressive fibrotic change in response to prolonged, repetitive, and typically severe insult to the peritoneal mesothelium, often occurring in the setting of peritoneal dialysis (PD. Clear guidelines for successful management remain elusive. We describe the successful surgical management of EPS in a 28-year-old male s/p deceased donor kidney transplant for end-stage renal disease (ESRD secondary to focal segmental glomerulosclerosis (FSGS. This patient received PD for 7 years but changed to hemodialysis (HD in the year of transplant due to consistent signs and symptoms of underdialysis. EPS was visualized at the time of transplant. Despite successful renal transplantation, EPS progressed to cause small bowel obstruction (SBO requiring PEG-J placement for enteral nutrition and gastric decompression. The patient subsequently developed a chronic gastrocutaneous fistula necessitating chronic TPN and multiple admissions for pain crises and bowel obstruction. He was elected to undergo surgical intervention due to deteriorating quality of life and failure to thrive. Surgical management included an exploratory laparotomy with extensive lysis of adhesions (LOA, repair of gastrocutaneous fistula, and end ileostomy with Hartmann’s pouch. Postoperative imaging confirmed resolution of the SBO, and the patient was transitioned to NGT feeds and eventually only PO intake. He is continuing with PO nutrition, gaining weight, and free from dialysis. Conclusion. Surgical intervention with LOA and release of small intestine can be successful for definitive management of EPS in the proper setting. In cases such as this, where management with enteral nutrition fails secondary to ongoing obstructive episodes, surgical intervention can be pursued in the interest of preserving quality of life.

    Risk factors for surgical site infection (SSI) after liver transplantation and outcomes associated with these infections have not been assessed using consensus surveillance and optimal analytic methods. A cohort study was performed of patients undergoing first liver transplantation at Mayo Clinic, Jacksonville, Florida, in 2003 and 2004. SSIs were identified by definitions and methods of the National Nosocomial Infections Surveillance System. Measures of known or suspected risk factors for SSI, graft loss, or death were collected on all patients. Associations of SSI with these factors and also with the primary composite endpoint of graft loss or death within 1 year of liver transplantation were examined using Cox proportional hazards models; relative risks (RRs) were estimated along with 95% confidence intervals (CIs). Of 370 patients, 66 (18%) had SSI and 57 (15%) died or sustained graft loss within 1 year after liver transplantation. Donor liver mass-to-recipient body mass ratio of less than 0.01 (RR 2.56; 95% CI 1.17-5.62; P=0.019) and increased operative time (RR 1.19 [1-hr increase]; 95% CI 1.03-1.37; P=0.018) were associated with increased SSI risk. SSI was associated with increased risk of death or graft loss within the first year after liver transplantation (RR 3.06; 95% CI 1.66-5.64; P<0.001). SSI is associated with increased risk of death or graft loss during the first year after liver transplantation. Increased operative time and decreased donor liver-to-recipient body mass ratio showed evidence of association with SSI.

    Full Text Available The authors report the long-term results of combined conjunctival autograft and overlay amniotic membrane transplantation (AMT for treatment of pterygium as a new surgical technique. Nineteen patients including 12 male and 7 female subjects with pterygium (primary, 14 cases; recurrent, 5 cases underwent combined conjunctival autograft and overlay AMT and were followed from 10 to 26 months. Mean age was 44.21±12.49 (range, 29.0-73.0 years. In one patient with grade T3 primary pterygium, the lesion recurred (5.2%, recurrence rate. No intra-and postoperative complication developed. This procedure seems a safe and effective surgical technique for pterygium treatment. Protection of the ocular surface during the early postoperative period reduces the friction-induced inflammation and might be helpful to prevent the recurrence.

    Red blood cell and component transfusions are a frequent and widely accepted accompaniment of surgical procedures. Although the risk of specific disease transmission via allogeneic blood transfusions (ABT) is very low, the occurrence of transfusion related immune modulation (TRIM) still remains a ubiquitous concern. Recent studies have shown that ABT are linked to increased morbidity and mortality across various specialties, with negative outcomes directly correlated to number of transfusions. Blood conservation methods are therefore necessary to reduce ABT. Acute normo-volemic hemodilution (ANH) along with pre-operative blood augmentation and intraoperative cell salvage are blood conservation techniques utilized in tertiary and even quaternary (transplantation) surgery in Jehovah's Witnesses with excellent outcomes. The many hematologic complications such as anemia, thrombocytopenia and coagulopathies that occur with liver transplantation present a significant barrier when trying to avoid ABT. Despite this, living donor liver transplantation (LDLT) has been successfully performed in a transfusion-free environment, providing valuable insight into the possibilities of limiting ABT and its associated risks in all patients.

    To evaluate the long-term efficacy of amniotic membrane transplantation for ocular surface reconstruction in the surgical management of ocular surface squamous neoplasia (OSSN). OSSN in 21 patients (7 female, 14 male patients) was managed with excisional biopsy, cryotherapy, corneal epitheliectomy with absolute alcohol application when the cornea is involved, lamellar sclerectomy and adjunctional absolute alcohol application to the base when episclera is involved, and ocular surface reconstruction with cryopreserved amniotic membrane transplantation. Tumor control and complications were evaluated. The mean age of the patients was 62.42 ± 20.9 (range, 16-84). The average diameter of the base of the tumors was 13.1 ± 4.8 (range, 9-21) mm and complete removal was achieved in all cases as revealed histopathologically. Ocular surface healing was achieved in all cases. At the postoperative period, limbal stem cell deficiency in three eyes and mild symblepharon in one eye were detected. In a mean follow-up of 30.95 ± 18.8 (range, 13-75) months, no recurrence was detected. For large or multifocal conjunctival tumors, the reconstruction of ocular surface and fornix is challenging. The amniotic-membrane use to repair conjunctival defects larger than 10 mm is a safe and effective technique with minimal complications allowing surgeons to make large enough excisions.

    To investigate the long-term efficacy and results of surgical management of conjunctival melanoma reconstructed with amniotic membrane transplantation. Conjunctival melanoma in 10 patients (5 female, 5 male) was totally excised with adjunctive cryotherapy to the surgical margins, corneal epitheliectomy with absolute alcohol in cases of corneal involvement, lamellar sclerectomy in cases with episcleral involvement, and ocular surface grafting with cryopreserved amniotic membrane. Complications and tumor control rates were evaluated. The mean age of the patients was 57.4±15.2 (range, 37-84) years. The mean diameter of the tumors was 15.5±4.9 (range, 10-25) mm and histopathologically confirmed complete excision was performed in all cases. Mild limbal stem cell deficiency (2 eyes) and subclinical symblepharon (3 eyes) were observed as long-term complications. In a mean follow-up of 56.7±40.4 (range, 30-132) months, only one local tumor recurrence was detected. Despite retreatment, exenteration was performed in this patient due to re-recurrence. One patient died due to disseminated metastasis despite the absence of local recurrence. In large conjunctival melanomas, reconstruction of the ocular surface is usually very challenging. The use of cryopreserved amniotic membrane for conjunctival defect repair is safe and effective with mild complications, and allows the excision of wider margins around the tumor.

Mild limbal stem cell deficiency (2 eyes and subclinical symblepharon (3 eyes were observed as long-term complications. In a mean follow-up of 56.7±40.4 (range, 30-132 months, only one local tumor recurrence was detected. Despite retreatment, exenteration was performed in this patient due to re-recurrence. One patient died due to disseminated metastasis despite the absence of local recurrence. Conclusion: In large conjunctival melanomas, reconstruction of the ocular surface is usually very challenging. The use of cryopreserved amniotic membrane for conjunctival defect repair is safe and effective with mild complications, and allows the excision of wider margins around the tumor.

    Acute pancreatitis is a rare but frequently fatal complication in patients following kidney transplantation. The first case of acute pancreatitis in patients following a kidney transplant was described by Starzl in 1964. The incidence of acute pancreatitis is stated at between 1 and 5%. The mortality rate amongst these patients reaches as high as 50-100%. Here we present a case of acute pancreatic abscess in a caucasian female - shortly following a kidney transplant complicated by the development of acute rejection, in which immunosuppressant therapy is a potential etiological agent. Emergency surgical treatment was indicated, which included drainage of the abscesses irrigation of the abdominal cavity. Immunosuppressive medication was considered a possible etiological factor, and as a result administration of tacrolimus and mycophenolate mofetil was discontinued. This was successful and three months later, diagnostic rebiopsy of the graft was performed without signs of rejection. The etiology of this illness is multifactorial. The clinical manifestation of acute pancreatitis in patients following kidney transplantation is the same as in the remainder of the population. However, in patients following transplantation with long-term immunosuppression, it usually manifests a more rapid development and a more severe, frequently fatal course. With regard to the patient's comorbidities, early surgical therapy was indicated - drainage and closed lavage and immunosuppressive medication as a suspected tobe ethiological factor was discontinued. This course of treatment led to a complete recovery with preservation of good function of the cadaverous kidney.

    Allograft lithiasis is a rare urologic complication of renal transplantation (RT). Our aim is to present our experience with minimally invasive surgical treatment of allograft lithiasis in our series of live-donor renal transplant recipients. In a retrospective analysis of 3758 consecutive live-donor RTs performed in our center between November 2009 and January 2017, the results of minimally invasive surgery for the treatment of renal graft lithiasis diagnosed at follow-up were evaluated. Twenty-two (0.58%) patients underwent minimally invasive surgery for renal graft lithiasis. The mean age was 41.6 years, and duration between RT and surgical intervention was 27.3 months (range 3-67). The mean stone size was 11.6 mm (range 4-29). Stones were located in the urethra in 1, bladder in 2, ureter in 9, renal pelvis in 7 and calices in 3 patients. Surgical treatment included percutaneous nephrolithotomy in 1, cystoscopic lithotripsy in 3, flexible ureteroscopic lithotripsy in 6 and rigid ureteroscopic lithotripsy in 12 patients. No major complications were observed. One patient (4.5%) who underwent flexible ureteroscopy developed postoperative urinary tract infection. All patients were stone-free except two (9%) patients who required a second-look procedure after flexible ureteroscopic lithotripsy for residual stones. Stone recurrence was not observed in any patient during a mean follow-up duration of 30.2 months (range 8-84). Renal transplant lithiasis is uncommon and minimally invasive surgical treatment is rarely performed for its treatment. Endourological surgery may be performed safely, effectively and with a high success rate in these patients.

    The learning curve in laparoscopic surgery may be associated with higher patient risk, which is unacceptable in the setting of kidney donation. Virtual reality simulators may increase the safety and efficiency of training in laparoscopic surgery. The aim of this study was to investigate if the results of a training session reflect the actual skill level of transplantation surgeons and whether the simulator could differentiate laparoscopic experienced transplantation surgeon from advanced trainees. 16 subjects were assigned to one of two groups: 5 experienced transplantation surgeon and 11 advanced residents, with only assistant role during transplantation. The level of performance was measured by a relative scoring system that combines single parameters assessed by the computer. The higher the level of transplantation experience of a participant, the higher the laparoscopic performance. Experienced transplantation surgeons showed statistically significant better scores than the advanced group for time and precision parameters. Our results show that performance of the various tasks on the simulator corresponds to the respective level of experience in transplantation surgery in our research groups. This study confirms construct validity for the LapSim. It thus measures relevant skills and can be integrated in an endoscopic training and assessment curriculum for transplantations surgeons.

    EstabLishment of hepato-pancreato-biliary (HPB) surgery and abdominal organ transplantation as defined subspecialties of general surgery has been boosted over the Last decade. However, the affiliation (independent service vs. integration within the division of surgery), the training course (transplantation vs. surgical oncology) and the referral patterns are still controversial. Dedicated HPB and transplantation units were defined within the surgical division of the Tel Aviv Medical Center. The principles of operation included muttidisciplinary expert teams, unified and standard treatment protocols, exposure and involvement of all residents and attending surgeons of the division to patients, decision-making and perioperative care, peer review and periodic publication of clinical results. Between the years 2003-2007, 870 major HPB procedures were performed: 70 Liver transplants (9 from live donors), 100 organ procurements, 165 kidney and kidney-pancreas transplants (30% from Live donors), 250 hepatic resections of various types and indications, 35 complex biliary reconstructions and 250 pancreatectomies. The short- (morbidity and mortality) and long-term (survival and disease free survival) rates are compatible with the reported results from Centers of Excellence around the world. Operating HPB and transplantation surgery by trained experts and defined professional units, but within an academic surgical division, promotes the achievement of high volume and excellent results together with optimal exposure, education and training of the surgical residents.

    Full Text Available Aim. Evaluation of the possibility heart valve replacement in renal transplant recipients from a position of safe- ty for graft function. Materials and methods. 5 patients, heart valve replacement was performed with a func- tioning kidney transplant at a satisfactory its function. The average age of patients at the time of cardiac surgery was 38,8 ± 12,6 years, among whom were two (40% men and 3 (60% women. The interval between renal transplantation and heart surgery was 40,3 ± 44,1 (2 to 120 months. Prior to kidney transplantation, all patients were on renal replacement therapy with hemodialysis program for 50,2 ± 48,6 months. In 4 of the 5 patients of heart disease was the cause of infective endocarditis. Results. Average time IR was 81,2 ± 21,7 minutes , the average time of aortic clamping 63,6 ± 20,9 minutes and hypothermia during CPB 29,2 ± 3,2 °C. All patients were implanted with double-leaf mechanical prostheses "MedEng-2" and "SarboMedics". All 5 patients in sa- tisfactory condition were discharged from the hospital. The average duration of the postoperative period was 14,2 ± 3,4 days. All patients had relatively smooth flow after surgery, no infectious complications, a satisfactory renal transplant function and prosthetic heart valves. In the late period in four patients and transplant graft func- tion is satisfactory in terms of the observation of 5 years, 3 years and 6 months after surgery. Conclusion. Our experience shows the possibility of successful correction of heart defects in IR in renal transplant recipients.

    The tracheostomy is a frequently used procedure for the respiratory weaning of ventilated patients allows sedation free ECLS use in awake patient. The aim of this study is to assess the possibility and highlight the benefits of lowering the impact of sedation in surgical non-transplant patients on ECLS. The specific objective was to investigate the use of tracheostomy as a bridge to spontaneous breathing on ECLS. Of the 95 patients, 65 patients received a tracheostomy, and 5 patients were admitted with a tracheostoma. One patient was cannulated without intubation, one is extubated during ECLS course after 48 hours. 4 patients were extubated after weaning and the removal of ECLS. 19 patients died before the indication to tracheostomy was given. Tracheostomy can bridge to spontaneous breathing and awake-ECMO in non-transplant surgical patients. The "awake ECMO" strategy may avoid complications related to mechanical ventilation, sedation, and immobilization and provide comparable outcomes to other approaches for providing respiratory support. © 2017 The Authors.

    Phaeohyphomycosis can be caused by a number of different species, being the most common Alternaria alternata and Alternaria infectoria. The biggest risk factor for the development of the infection is immunosuppression. We present the case of a 64-year-old male renal transplant patient who came to hospital for presenting a tumour in the Achilles region which had been gradually growing in size. A skin biopsy was taken for histological study and culture of fungi and mycobacteria. Blood tests and imaging studies were performed. Histopathology study and cultures identified A. infectoria as the causal agent. Imaging studies ruled out internal foci of infection. The lesion was surgically removed with no signs of recurrence after 24 months of follow-up. There are no treatment guidelines at present for cutaneous and subcutaneous Alternaria spp. infections. Various systemic antifungals have been used, either in combination with surgical removal or alone, with varying results. Surgery alone could be useful in the treatment of solitary, localised lesions in transplant patients in whom there are difficulties in controlling immunosuppression.

    The United Network for Organ Sharing recommends that fellowship-trained surgeons participate in 15 laparoscopic donor nephrectomy (LDN) procedures to be considered proficient. The American Society of Transplant Surgeons (ASTS) mandates 12 LDNs during an abdominal transplant surgery fellowship. We performed a retrospective intraoperative case analysis to create a risk-adjusted cumulative summation (RACUSUM) model to assess the learning curve of novice transplant surgery fellows (TSFs). Between January 2000 and December 2014, 30 novice TSFs participated in the organ procurement rotation of our ASTS-approved abdominal transplant surgery fellowship. Measures of surgical performance included intraoperative time, estimated blood loss, and incidence of intraoperative complications. The performance of senior TSFs was used to benchmark novice TSF performance. Scores were tabulated in a learning curve model, adjusting for case complexity and prior TSF case volume. Rates of adverse surgical events were significantly higher for novice TSFs than for senior TSFs. In univariable analysis, multiple renal arteries, high BMI, prior abdominal surgery, male donor, and nephrolithiasis were correlated with higher incidence of adverse surgical events. Based on the RACUSUM model, high intraoperative time is mitigated after 28 procedures, incidence of intraoperative complications tends to diminish after 24 procedures, and improvement in estimated blood loss did not remain consistent. TSFs exhibit a tipping point in LDN performance by 24-28 cases and proficiency by 35-38 cases. © 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Although it is the only curative treatment for polycystic liver disease (PLD), orthotopic liver transplantation (OLT) has been reserved for severely symptomatic, malnourished, or refractory patients who are not candidates for palliative disease-directed interventions (DDI). Data on the effect of previous DDIs on post-transplant morbidity and mortality are scarce. We analyzed the outcomes after OLT for PLD recipients, and determined the effects of previous palliative surgical intervention on post-transplantation morbidity and mortality. We performed a retrospective analysis of factors affecting perioperative outcomes after OLT for PLD between 1992 and 2013, including comparisons of recipients with previous major open DDIs (Open DDI, n = 12) with recipients with minimally invasive or no previous DDIs (minimal DDI, n = 16). Over the 20-year period, 28 recipients underwent OLT for PLD, with overall 30-day, 1-, and 5-year graft and patient survivals of 96%, 89%, 75%, and 96%, 93%, 79%, respectively. Compared with the minimal DDI group, open DDI recipients accounted for all 5 deaths, had inferior 90-day and 1- and 5-year survivals (83%, 83%, and 48% vs 100%, 100%, 100%; p = 0.009), and greater intraoperative (42% vs 0%; p = 0.003), total (58% vs 19%; p = 0.031), and Clavien grade IV or greater (50% vs 6%; p = 0.007) postoperative complications, more unplanned reoperations (50% vs 13%; p = 0.003), and longer total hospital (27 days vs 17 days; p = 0.035) and ICU (10 days vs 4 days; p = 0.045) stays. In one of the largest single-institution experiences of OLT for PLD, we report excellent long-term graft and patient survival. Previous open DDIs are associated with increased risks of perioperative morbidity and mortality. Improved identification of PLD patients bound for OLT may mitigate perioperative complications and potentially improve post-transplantation outcomes. Copyright © 2014 American College of Surgeons.

    Invasive Zygomycetes infection complicating prolonged neutropenia is associated with high mortality in the absence of immune recovery. We report a patient who developed disseminated zygomycosis due to Rhizopus microsporus during induction chemotherapy for acute myeloid leukemia. Rescue allogeneic hematopoietic stem cell transplantation (allo-HSCT) was performed as her only chance of cure of this infection and to treat refractory leukemia. Posaconazole combined with liposomal amphotericin B contained the zygomycosis during prolonged neutropenia due to allo-HSCT followed by intense immunosuppression for grade IV acute graft-versus-host disease. Surgical removal of all infected sites after immune recovery, with prolonged posaconazole treatment, ultimately cured the infection. New combination antifungal therapies might sufficiently control disseminated zygomycosis to allow allo-HSCT to be performed, assuring life-saving immune recovery. Surgery appears to be necessary for definite cure of these infections.

    Precise evaluation of the live donor's liver is the most important factor for the donor's safety and the recipient's prognosis in living donor liver transplantation (LDLT). Our study assessed the clinical value of computer-assisted three-dimensional quantitative assessment and a surgical planning tool for donor evaluation in LDLT. Computer-assisted three-dimensional (3D) quantitative assessment was used to prospectively provide quantitative assessment of the graft volume for 123 consecutive donors of LDLT and its accuracy and efficiency were compared with that of the standard manual-traced method. A case of reduced monosegmental LDLT was also assessed and a surgical planning tool displayed the precise surgical plan to avoid large-for-size syndrome. There was no statistically significant difference between the detected graft volumes with computer-assisted 3D quantitative assessment and manual-traced approaches ((856.76 ± 162.18) cm(3) vs. (870.64 ± 172.54) cm(3), P = 0.796). Estimated volumes by either method had good correlation with the actual graft weight (r-manual-traced method: 0.921, r-3D quantitative assessment method: 0.896, both P assisted 3D quantitative assessment approach was significantly more efficient taking half the time of the manual-traced method ((16.91 ± 1.375) minutes vs. (39.27 ± 2.102) minutes, P size syndrome. Computer-assisted 3D quantitative assessment provided precise evaluation of the graft volume. It also assisted surgeons with a better understanding of the hepatic 3D anatomy and was useful for the individual surgical planning tool.

We present our single centre experience in the urological management of this clinically challenging condition. Patients and Methods: Fourteen patients were diagnosed with BK-Virus HC in our centre. The mean age at diagnosis was 8.8 years (range, 3.2-18.4 years. The mean number of days post-BMT until onset of HC was 20.8 (range, 1 – 51. While all patients tested urine positive for BKV at the clinical onset of HC, only four patients had viral quantification, with viral loads ranging from 97,000 to >1 billion/ml. 8 patients had clinical HC. Ten patients experienced acute GVHD (grade I: 6 patients, grade II: 3 patients, grade 4: 1 patient.Results: Four patients received medical management for their HC.

    Living-related liver transplantation was developed in the context of deceased donor organ shortage, which is particularly acute for pediatric recipients. This retrospective study analyzes the surgical technique and complications in the first 100 pediatric liver transplantation using left segmental liver grafts from living donors, performed at Saint-Luc University Clinics between July 1993 and April 2002. Pre-operative evaluation in donors and recipients, analysis of the surgical technique, and postoperative complications were reviewed. After a median follow-up period of 2526 days, no donor mortality was encountered, with a minimal morbidity and no long-term sequelae. At one and five yr post-transplantation, the actuarial patient survival rates were 94% and 92%, the corresponding figures being 92% and 89% for graft survival. The incidences of portal vein and hepatic artery thromboses, and of biliary complications were 14%, 1%, and 27%, respectively. Living-related liver transplantation in children constitutes an efficient therapy for liver failure to face the increased demand for liver grafts. Donor morbidity was kept to acceptable incidence, and surgical technique in the recipient needs to be tailored to minimize postoperative complications.

    Transplantable organs from pediatric donors have been contributing significantly to donor pool worldwide. Pediatric donors are excellent resources that should be procured whenever available, and with the recent increase in deceased donations in India, more pediatric donors will be available for organ harvesting. We share a rare instance of multi-organ harvesting from a 16-month old brain dead donor and implanting both kidneys en-bloc in an adult male, while liver went to a 4-year old child. The report provides the surgical illustration of salient steps of transplanting both kidneys from pediatric donor into an adult, in an en-bloc manner.

    Oroantral fistula (OAF) is considered a frequent complication in dental practice. Many surgical techniques/methods have been proposed to close it. The aim of this study was to evaluate the auto-transplantation of upper third molar for closing OAF. Twenty patients participated in this study aged between 20 and 40 years old. The OAF was closed by auto-transplantation of upper third molar placed directly in the socket of the extracted tooth. Results were evaluated clinically and radiographically through the period of observation which lasted for 1 year. Final results showed that the success rate of closing OAF was 95% while the success rate of upper third molar auto-transplantation was 90%. This technique is simple, applicable, provides immediate replacement of the missing tooth, and does not require complicated instruments or procedures.

    In dogs with deep analgesia caused by acute spinal cord injury from thoracolumbar disk herniation, autologous bone marrow mononuclear cell transplant may improve recovery. The purpose of the present study was to evaluate autologous bone marrow mononuclear cell transplant in a dog that had paraplegia and deep analgesia caused by chronic spinal cord injury. Autologous bone marrow mononuclear cell transplant was performed in a dog having paraplegia and analgesia for 3 years that was caused by a chronic spinal cord injury secondary to Hansen type I thoracolumbar disk herniation. Functional recovery was evaluated with electrophysiologic studies and the Texas Spinal Cord Injury Scale. Somatosensory evoked potentials were absent before transplant but were detected after transplant. Functional improvement was noted (Texas Spinal Cord Injury Scale: before transplant, 0; after transplant, 6). No adverse events were observed. Autologous bone marrow mononuclear cell transplant into the subarachnoid space may be a safe and beneficial treatment for chronic spinal cord injury in dogs.

    The small diameter of the hepatic artery is one of the complexities of living donor liver transplantation (LDLT). We analyzed whether the direct suture technique using surgical loupes can simplify the operative process for LDLT compared with fixed microscopic reconstruction. We applied the direct technique to rationalize the operative process and abolished routine microsurgery from 2004. Two hundred and nine LDLT with a postoperative period over 34 months were carried out from 1996 to 2008. The patients were divided into two groups: the micro group (children: 20, adults: 72) and the non-micro group (children: 12, adults: 97). Running anastomosis was undertaken in the non-micro group. The anastomotic size of the children was significantly smaller than that of the adults, but larger than 2 mm (2.38±0.4 vs. 2.7±0.47 mm, p=0.0005). By appropriate choice of the proximal artery, direct anastomosis is possible even in children. Early complications occurred in seven cases in the micro group, but none occurred in the non-micro group (prationalization of LDLT. © 2012 John Wiley & Sons A/S.

    Living donor surgery in organ transplantation should be performed in a minimally invasive manner under conditions that are as safe as possible. The objective of this study is to examine whether the procedure for using the ovarian vein makes donor surgery less invasive in a cynomolgus monkey model of potential living-donor surgery of uterus transplantation. Twenty-two female cynomolgus monkeys aged 6-9 years and with body weights of 3.55 ± 1.28 kg were used in the study. Vessels and tissues surrounding the uterus were dissected while preserving the uterine artery/vein. The deep uterine vein was used as a venous pedicle in four monkeys (Group 1), and the ovarian vein was used instead of the deep uterine vein in 18 monkeys (Group 2). With the uterine artery/vein and deep uterine vein (Group 1) or ovarian vein (Group 2) connected to the uterus, the vaginal canal was cut. The vessels were then clamped to produce a donor surgery model. Surgical time, intraoperative organ and vascular injury were examined in each animal. The average surgical time from laparotomy to clamping of vessels was 230 ± 112 min in all 22 cynomolgus monkeys, and significantly longer in Group 1 (n = 4) than in Group 2 (n = 18) (393 ± 71 vs. 194 ± 84 min, p uterus transplantation. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

    Pancreatic cancer is the third most common cancer related cause of death. Even in the 15% of patients who are eligible for surgical resection the outlook is dismal with less than 10% of patients surviving after 5 years. Allogeneic hematopoietic (allo-HSCT) stem cell transplantation is an established treatment capable of to providing cure in a variety of hematopoietic malignancies. Best results are achieved when the underlying neoplasm has been turned into a stage of minimal disease by chemotherapy. Allo-HSCT in advanced solid tumors including pancreatic cancer have been of limited success, however studies of allo-HSCT in solid tumors in minimal disease situations have never been performed. The aim of this trial is to provide evidence for the clinical value of allo-HSCT in pancreatic cancer put into a minimal disease status by effective surgical resection and standard adjuvant chemotherapy. The STEM PACE trial is a single center, phase II study to evaluate adjuvant allogeneic hematopoietic stem cell transplantation in pancreatic cancer after surgical resection. The study will evaluate as primary endpoint 2 year progression free survival and will generate first time state-of-the-art scientific clinical evidence if allo-HSCT is feasible and if it can provide long term disease control in patients with effectively resected pancreatic cancer. Screened eligible patients after surgical resection and standard adjuvant chemotherapy with HLA matched related stem cell donor can participate. Patients without a matched donor will be used as a historical control. Study patients will undergo standard conditioning for allo-HSCT followed by transplantation of allogeneic unmanipulated peripheral blood stem cells. The follow up of the patients will continue for 2 years. Secondary endpoints will be evaluated on 7 postintervention visits. The principal question addressed in this trial is whether allo-HSCT can change the unfavourable natural course of this disease. The underlying

    This study was to evaluate clinical and microbiological effectiveness of photodynamic therapy (PDT) in the treatment of periodontal disease in kidney-transplanted patients. Eight kidney transplanted patients treated at Paulista University were arranged in two groups: SRP performed scaling and root planning by ultrasound; SRP+PDT- in the same patient, which was held to PDT in the opposite quadrant, with 0.01% methylene blue and red laser gallium aluminum arsenide, wavelength 660 nm, power 100 mW. There was reduction in probing pocket depth after 45 days and 3 months regardless the group examined; plaque and bleeding index showed improvement over time, regardless the technique used, and bleeding index in the SRP+PDT group was lower when compared with the baseline the other times. There was no difference in the frequency of pathogens. Photodynamic therapy may be an option for treatment of periodontal disease in renal-transplanted patients and its effectiveness is similar to conventional therapy.

    Full Text Available Purpose. To determine if the use of combined HLA matched limbal stem cells allograft with amniotic membrane transplantation (AMT is a safe and effective prophylactic surgical procedure to prevent corneal graft after penetrating keratoplasty (PK. Methods. We report the case of a 17 years old patient with a history of congenital glaucoma, trabeculectomy and multiple corneal graft rejections, presenting total limbal cell deficiency. To reduce the possibility of graft rejection in the left eye after a new PK, a two step procedure was performed. At first the patient underwent a combined HLA matched limbal stem cells allograft (LAT and AMT and then, 10 months later, a new PK. Results. During 12 months of follow-up, the corneal graft remained stable and smooth, with no sign of graft rejection. Conclusions. In our patient, the prophylactic use of LAT from HLA-matched donors and AMT before PK, may result in a better prognosis of corneal graft survival.

    The present study developed an effective surgical planning method consisting of a liver extraction stage, a vessel extraction stage, and a liver segment classification stage based on abdominal computerized tomography (CT) images. An automatic seed point identification method, customized level set methods, and an automated thresholding method were applied in this study to extraction of the liver, portal vein (PV), and hepatic vein (HV) from CT images. Then, a semi-automatic method was developed to separate PV and HV. Lastly, a local searching method was proposed for identification of PV branches and the nearest neighbor approximation method was applied to classifying liver segments. Onsite evaluation of liver segmentation provided by the SLIVER07 website showed that the liver segmentation method achieved an average volumetric overlap accuracy of 95.2%. An expert radiologist evaluation of vessel segmentation showed no false positive errors or misconnections between PV and HV in the extracted vessel trees. Clinical evaluation of liver segment classification using 43 CT datasets from two medical centers showed that the proposed method achieved high accuracy in liver graft volumetry (absolute error, AE = 45.2 ± 20.9 ml; percentage of AE, %AE = 6.8% ± 3.2%; percentage of %AE > 10% = 16.3%; percentage of %AE > 20% = none) and the classified segment boundaries agreed with the intraoperative surgical cutting boundaries by visual inspection. The method in this study is effective in segmentation of liver and vessels and classification of liver segments and can be applied to preoperative liver surgical planning in living donor liver transplantation.

    Chronic intestinal pseudo-obstruction (CIPO) is a recurrent disorder caused by intestinal dysmotility. Although, CIPO is not a surgically remediable condition, surgery is a common issue in CIPO patients. The aim of this study was to assess postoperative morbidity and mortality of patients operated on for CIPO and risk of re-operation. Adult patients that have undergone surgery for CIPO since 1980 were included in this retrospective study using a prospective database. Postoperative morbidity, according to Clavien-Dindo classification and CIPO-related re-operation rates were evaluated with univariate and multivariate analysis. Sixty-three patients (33 women, median age 37 [range: 15-79] years) were included. Median follow-up was 6 (0.2-28) years. Overall postoperative mortality rate was 7.9%. Overall morbidity rate was 58.2% (Clavien-Dindo ≥3 in 20.7%) leading to re-operation in 17% of cases. In multivariate analysis, major postoperative morbidity (Clavien-Dindo ≥3) was significantly increased when there was an intraoperative bowel injury (HR = 15.7 [2.4-102], P = 0.004), idiopathic CIPO (HR = 4.2 [1.5-12], P = 0.007) and emergency procedure (HR = 3 [1.3-6.8]. After the first surgery, probabilities of CIPO-related re-operation were 44%, 60%, and 66% at 1, 3, and 5 years respectively. In multivariate analysis, CIPO-related reoperation for CIPO was significantly increased when there was a major postoperative morbidity (HR = 2.1 [1.1-4.4], P = 0.040) and intraoperative bowel injury (HR = 33.1 [2-553], P = 0.015) after the first procedure. The surgical management of CIPO patients was associated with high postoperative morbidity and mortality rates and frequent re-operation. Attempts should be made to avoid surgery when possible and optimize nutritional status. © 2013 John Wiley & Sons Ltd.

    to treat special cases of intestinal failure. AIM: This review highlights recent developments in the area of small bowel transplantation. MATERIAL AND METHODS: Over 600 reports on clinical and experimental small bowel transplantation were reviewed. Aspects concerning research development, different immunosuppressive strategies, patient and graft monitoring, and improvements in surgical techniques are discussed. RESULTS: About 700 small bowel transplantation were performed in 55 transplant centers, 44% intestine-liver, 41% isolated intestinal graft and 15% multivisceral transplantation. Rejection and infection are the main limitation of this procedure. Actual 5 years post transplantation graft survival of the total international experience is 46% for isolated intestinal graft, 43% for combined intestine-liver and nearly 30% for multivisceral transplantation. Higher graft and patient survival are seen at the more experienced centers. In a series of 165 intestinal transplantation at University of Pittsburgh, PA, USA, actuarial patient survival was reported to be over 75% at one year, 54% at 5 years and 42% at 10 years. Over 90% patients from Pittsburgh program resume an unrestricted oral diet. CONCLUSION: Small bowel transplantation has advanced from an experimental strategy to a feasible alternative for patients with permanent intestinal failure. Further refinements in graft acceptance, immunosuppressive regiments, infection management and prophylaxis, surgical techniques as well as appropriated patient referral and selection are crucial to improve outcomes.

    Psychologic disturbances are becoming more common in kidney transplantation, owing to effects of immunosuppressive therapy. In this study, we explored the incidence and specifity of psychopathology among kidney transplant patients. Twenty kidney transplant recipients underwent the Machover Draw-A-person test to detect significant variables (V1=V6) hypothetically related to chronologic age, education, years from transplantation, and gender differences. Emotional coarctation (V1) in the sense of "mental rigidity," "egocentrism," and "hypercontrol" were present in all transplant recipients (100%), followed by difficulty in interpersonal relationships (V3; 70%) and anxiety (V5; 70%). This research confirmed the hypothesis that transplantation can display a potential risk to the psychologic balance of the patient. Psychologic evaluation may be a fundamental step together with surgical aspects and management of immunosuppression to achieve well-being of kidney transplant recipients.

    To determine the cost effectiveness of transplantation, we analyzed the financial economics of the organ and tissue transplant process. We compared the cost of this process with traditional modalities for treating endstage liver and kidney disease. Medical, surgical, legal, social, ethical, and religious issues are important in organ transplant procedures. Government, health insurance companies, and uninsured individuals are affected by the financial economics of organ transplantation. The distribution of financial burden differs among countries and is dependent on the unique circumstances of each country.

    This book covers all topics related to the imaging of organ transplantation. An introductory section addresses such issues as organ procurement, patient selection, immune responses, and ethical and economic considerations. The main part of the book then offers in-depth coverage of heart, renal, liver, lung, bone marrow and pancreatic and intestinal transplantation. Each of these topics is discussed firstly in a clinical chapter and then in a radiological chapter. The clinical chapters detail the epidemiology, clinical background, and surgical procedures, as well as any clinically relevant issues of which the radiologist should be aware. The radiological chapters describe and depict the imaging manifestations of specific organ transplantations, document the normal radiological appearance of transplanted organs and consider both early and late complications. This is a unique, superbly illustrated volume that will be of great assistance to all who work in this field. (orig.)

    Malignant melanoma of the conjunctiva is a rare tumor with incidence of 0.5 cases/year per million population. It may also occur as de novo, as on the basis of preexisting melanocytic lesions (nevus or freckle) or most often from the so-called primary acquired melanosis of the conjuctiva (PAM). It metastasizes mainly lymphogenic and hematogenous. The size of the primary tumor lesion, histopathological findings and absolute tumor thickness are essential for unfavorable prognosis. Conjunctival auto transplantation from the other eye is modern and innovative, but also a seldomly feasible method of reconstruction after conjunctival excision of tumors in this area. We present a rare case of a 75-year-old patient with epithelioid cell malignant melanoma of the bulbar conjunctiva of the right eye, which de novo occurred, successfully treated by excision of the primary tumor and subsequent reconstruction by conjunctival auto transplant from the other eye. A very good therapeutic and aesthetic result was achieved.

    Access to organ transplantation depends on national circumstances, and is partly determined by the cost of health care, availability of transplant services, the level of technical capacity and the availability of organs. Commercial transplantation is estimated to account for 5%-10% (3500-7000) of kidney transplants performed annually throughout the world. This review is to determine the state and outcome of renal transplantation associated with transplant tourism (TT) and the key challenges with such transplantation. The stakeholders of commercial transplantation include: patients on the waiting lists in developed countries or not on any list in developing countries; dialysis funding bodies; middlemen, hosting transplant centres; organ-exporting countries; and organ vendors. TT and commercial kidney transplants are associated with a high incidence of surgical complications, acute rejection and invasive infection which cause major morbidity and mortality. There are ethical and medical concerns regarding the management of recipients of organs from vendors. The growing demand for transplantation, the perceived failure of altruistic donation in providing enough organs has led to calls for a legalised market in organ procurement or regulated trial in incentives for donation. Developing transplant services worldwide has many benefits - improving results of transplantation as they would be performed legally, increasing the donor pool and making TT unnecessary. Meanwhile there is a need to re-examine intrinsic attitudes to TT bearing in mind the cultural and economic realities of globalisation. Perhaps the World Health Organization in conjunction with The Transplantation Society would set up a working party of stakeholders to study this matter in greater detail and make recommendations.

    Full Text Available Amit Sharma, Rajesh Ramanathan, Marc Posner, Robert A Fisher Hume-Lee Transplant Center, Virginia Commonwealth University, Richmond, VA, USA Abstract: Pediatric kidney transplantation is the preferred treatment for children with end-stage renal disease. The most common indications for transplantation in children are renal developmental anomalies, obstructive uropathy, and focal segmental glomerulosclerosis. Living donor kidney transplants are often performed pre-emptively and offer excellent graft function. Policy changes in deceased-donor kidney allocation have increased the proportion of such transplants in pediatric recipients. Adequate pretransplant workup along with evaluation of urologic abnormalities is imperative in achieving good outcomes. Overall, patient and graft outcomes after kidney transplantation have improved, with five-year deceased donor and living donor graft survivals of 78.8% and 84.3%, respectively. Improvements in induction and maintenance immunosuppression have contributed to the gradual improvement in outcomes. Unique challenges in pediatric recipients include increased graft thrombosis, adverse growth, and abnormal development relating to immunosuppression, increased rejection due to nonadherence, increased susceptibility to opportunistic infections, and post-transplant malignancy. This review focuses on the current practices and outcomes in pediatric kidney transplantation in North America. We discuss the indications for transplantation, the evaluation process, some key surgical and immunologic considerations, and the common risk factors for graft dysfunction.

    Full Text Available Abstract Background Lung transplantation (LTx is widely accepted as a therapeutic option for end-stage respiratory failure in cystic fibrosis. However, airway complications remain a major cause of morbidity and mortality in these patients, serious airway complications like bronchopleural fistula (BPF are rare, and their management is very difficult. Case presentation A 47-year-old man with end-stage respiratory failure due to cystic fibrosis underwent bilateral sequential lung transplantation. Severe post-operative bleeding occurred due to dense intrapleural adhesions of the native lungs. He was re-explored and packed leading to satisfactory haemostasis. He developed a bronchopleural fistula on the 14th post-operative day. The fistula was successfully repaired using pericardial and intercostal vascular flaps with veno-venous extracorporeal membrane oxygenator (VV-ECMO support. Subsequently his recovery was uneventful. Conclusion The combination of pedicled intercostal and pericardial flaps provide adequate vascular tissue for sealing a large BPF following LTx. Veno-venous ECMO allows a feasible bridge to recovery.

    Airway complications remain a significant source of morbidity and mortality after lung transplantation. The incidence of complications is wide-ranging depending on the definition of the event, and there is still no universally accepted grading system for airway findings after transplantation. Additionally, although surgical technique and organ preservation have improved, other modifiable risk factors remain unclear. The management is as wide-ranging as the definitions. A multimodality approach is often needed with airway stenting reserved for refractory cases and stent management by a transplant team with expertise in placement and management of long-term complications."

    The purpose was to assess the volumes of the different hepatic territories and especially the drainage of the right paramedian sector in adult living donor liver transplantation (ALDLT). CT was performed in 40 potential donors of whom 28 underwent partial living donation. Data sets of all potential donors were postprocessed using dedicated software for segmentation, volumetric analysis and visualization of liver territories. During an initial period, volumes and shapes of liver parts were calculated based on the individual portal venous perfusion areas. After partial hepatic congestion occurring in three grafts, drainage territories with special regard to MHV tributaries from the right paramedian sector, and the IRHV were calculated additionally. Results were visualized three-dimensionally and compared to the intraoperative findings. Calculated graft volumes based on hepatic venous drainage and graft weights correlated significantly (r=0.86,P<0.001). Mean virtual graft volume was 930 ml and drained as follows: RHV: 680 ml, IRHV: 170 ml (n=11); segment 5 MHV tributaries: 100 ml (n=16); segment 8 MHV tributaries: 110 ml (n=20). When present, the mean aberrant venous drainage fraction of the right liver lobe was 28%. The evaluated protocol allowed a reliable calculation of the hepatic venous draining areas and led to a change in the hepatic venous reconstruction strategy at our institution. (orig.)

    Uterus transplantation is today the only available treatment for absolute uterine factor infertility which is caused by either congenital/surgical uterine absence or that a present uterus is non-functioning. Structured animal-based research, from rodents to nonhuman primates, was the scientific basis for a successful introduction of uterus transplantation as a clinical procedure. The patient groups for uterus transplantation, the preclinical research and data from the published human cases will be covered herein. During recent years the concept of bioengineering of organs and tissues has emerged. Creation of a bioengineered uterus is in the initial research state, with experiments performed in rodents. The research that has been performed to create a bioengineered uterus will be summarized. In conclusion, uterus transplantation is now a clinical experimental procedure for treatment of uterine factor infertility. In parallel to the establishment of this combined assisted reproduction technique and transplantation procedure as a routine clinical procedure, we predict that uterus bioengineering will develop further towards introduction within the human setting, but that this process will take several years.

    Renal transplantation is the treatment of choice for renal insufficiency. Progress of surgical techniques and immuno-suppression have lead to better results. One year graft survival rate are 80% in most series. In this article, the role of imaging in renal transplantation, is defined. In surgical complications (fluid collections, obstruction, vascular insufficiency) non invasive radiology and interventionnal radiologic procedures have a great impact. Despite the perspectives of duplex and magnetic resonance, sensibility and specificity are not yet specified in medical complications: rejection, acute tubular necrosis, infection, drug toxicity. Association of these lesions is frequent and complicate analysis of results. Finally, transplant biopsy is still necessary to confirm the diagnosis [fr

    José Luiz Pedroso

    Full Text Available ABSTRACT Solid organ transplantation is a significant development in the treatment of chronic kidney, liver, heart and lung diseases. This therapeutic approach has increased patient survival and improved quality of life. New surgical techniques and immunosuppressive drugs have been developed to achieve better outcomes. However, the variety of neurological complications following solid organ transplantation is broad and carries prognostic significance. Patients may have involvement of the central or peripheral nervous system due to multiple causes that can vary depending on time of onset after the surgical procedure, the transplanted organ, and the intensity and type of immunosuppressive therapy. Neurological manifestations following solid organ transplantation pose a diagnostic challenge to medical specialists despite extensive investigation. This review aimed to provide a practical approach to help neurologists and clinicians assess and manage solid organ transplant patients presenting with acute or chronic neurological manifestations.

    BACKGROUND: Current techniques of management of carinal lesions are not always satisfactory. Carinal transplantation, if feasible, would be valuable in certain circumstances. METHODS AND RESULTS: Carinal transplantation experiments were performed in dogs. In early cross transplant experiments there were problems in controlling ventilation and in obtaining satisfactory anastomoses, and the animals failed to live for even a few days. In seven subsequent experiments the carinal graft was removed from one dog and transplanted into a second dog. Two dogs lived for over four months with immunosuppression. CONCLUSION: The results suggest that carinal transplantation can succeed if (1) the calibre of the graft is matched with that of the recipient; (2) there is an abundant blood supply to the graft; (3) appropriate immunosuppression is provided; (4) ventilation is adequate during surgery.

    Full Text Available OBJECTIVE: Assessment of incidence and behavior of mediastinitis after cardiac transplantation. METHODS: From 1985 to 1999, 214 cardiac transplantations were performed, 12 (5.6% of the transplanted patients developed confirmed mediastinitis. Patient's ages ranged from 42 to 66 years (mean of 52.3±10.0 years and 10 (83.3% patients were males. Seven (58.3% patients showed sternal stability on palpation, 4 (33.3% patients had pleural empyema, and 2 (16.7% patients did not show purulent secretion draining through the wound. RESULTS: Staphylococcus aureus was the infectious agent identified in the wound secretion or in the mediastinum, or both, in 8 (66.7% patients. Staphylococcus epidermidis was identified in 2 (16.7% patients, Enterococcus faecalis in 1 (8.3% patient, and the cause of mediastinitis could not be determined in 1 (8.3% patient. Surgical treatment was performed on an emergency basis, and the extension of the débridement varied with local conditions. In 2 (16.7% patients, we chose to leave the surgical wound open and performed daily dressings with granulated sugar. Total sternal resection was performed in only 1 (8.3% patient. Out of this series, 5 (41.7% patients died, and the causes of death were related to the infection. Autopsy revealed persistence of mediastinitis in 1 (8.3% patient. CONCLUSION: Promptness in diagnosing mediastinitis and precocious surgical drainage have changed the natural evolution of this disease. Nevertheless, observance of the basic precepts of prophylaxis of infection is still the best way to treat mediastinitis.

    Since the advent of ex vivo lung perfusion (EVLP), there has been increased focus on swine models of lung transplantation; however, the anatomic differences between human and swine lungs and the technical challenges in performing porcine lung transplantation are not well described in the surgical literature. Surgically important anatomic variations are described, and the technical measures taken to address them during harvest and transplantation are introduced. There are three surgically important anatomic variations in pigs. First, the right cranial lobe bronchus arises directly from the trachea, which makes right lung transplantation technically challenging if not prohibitive. Second, the left hemi-azygos vein is fully developed and courses upward through the posterior mediastinum, where it crosses the left pulmonary hilum and drains directly into the coronary sinus. During transplantation, this vein is ligated and dissected away to expose the underlying left pulmonary hilar structures. Third, the right inferior pulmonary vein crosses the midline to drain into the left atrium immediately adjacent to the left inferior pulmonary vein. During donor lung preparation, the right inferior pulmonary vein is ligated distally from the left atrium, which leaves an adequate atrial cuff around the left sided pulmonary veins for later anastomosis. Experimental porcine lung transplantation is technically demanding. We have found recognition of the above described anatomical differences and technical nuances facilitate transplantation and provide reproducible results. Copyright © 2011 Elsevier Inc.

    Full Text Available Although obesity has been associated with improved survival on dialysis, its short-and long-term effects on renal transplantation outcomes remain unclear. Herein, we evaluate the short-term and intermediate long-term effects of obesity on first-time renal transplant patients. A retrospective analysis was performed on 180 consecutive renal transplant recipients from living unrelated donors during 2006-2008 in a major transplantation center in Tehran, Iran. Among these, 34 (18% patients were found to be obese (body mass index ≥30 kg/m 2 . Obese patients were more likely to develop post-transplant renal artery stenosis (RAS (17.6% vs. 2.8%, P <0.001, hematoma (47.9% vs. 17.6, P = 0.009, surgical wound complications (64.7% vs. 9.6%, P <0.001 and renal vein thrombosis (2% vs. 0%, P <0.001. However, the incidence of delayed graft function, lymphocele, urologic complications of ureterovesical junction stenosis or urinary leakage, surgical complications of excessive bleeding or renal artery thrombosis and duration of hospitalization were similar between the two groups. The two-year patient and graft survival were also statistically not different. Renal transplantation in obese recipients is associated with a higher incidence of post-transplant RAS, hematoma, surgical wound complications and renal vein thrombosis, but similar two-year patient and graft survival.

    Despite the rapidly increasing prevalence of obesity in the transplant population, the optimal management of obese liver transplant candidates remains undefined. Setting strict body mass index cutoffs for transplant candidacy remains controversial, with limited data to guide this practice. Body mass index is an imperfect measure of surgical risk in this population, partly due to volume overload and variable visceral adiposity. Weight loss before transplantation may be beneficial, but it remains important to avoid protein calorie malnutrition and sarcopenia. Intensive lifestyle modifications appear to be successful in achieving weight loss, though the durability of these interventions is not known. Pretransplant and intraoperative bariatric surgeries have been performed, but large randomized controlled trials are lacking. Traditional cardiovascular comorbidities are more prevalent in obese individuals and remain the basis for pretransplant cardiovascular evaluation and risk stratification. The recent US liver transplant experience demonstrates comparable patient and graft survival between obese and nonobese liver transplant recipients, but obesity presents important medical and surgical challenges during and after transplant. Specifically, obesity is associated with an increased incidence of wound infections, wound dehiscence, biliary complications and overall infection, and confers a higher risk of posttransplant obesity and metabolic syndrome-related complications. In this review, we examine current practices in the obese liver transplant population, offer recommendations based on the currently available data, and highlight areas where additional research is needed.

    2015-01-01

    The first liver transplantation (LT) was performed by Thomas E Starzl five decades ago, and yet it remains the only therapeutic option offering gold standard treatment for end-stage liver disease (ESLD) and acute liver failure (ALF) and certain early-stage liver tumors. Post-liver transplantation survival has also dramatically improved over the last few decades despite increasing donor and recipient age and more frequent use of marginal organs to overcome the organ shortage. Currently, the overall 1 year survival following LT in the United States is reported as 85 to 90%, while the 10 years survival rate is ~50% (http://www.unos.org). The improvements are mainly due to progress in surgical techniques, postoperative intensive care, and the advent of new immunosuppressive agents. There are a number of factors that influence the outcomes prior to transplantation. Since 2002, the model for end-stage liver disease (MELD) score has been considered a predicting variable. It has been used to prioritize patients on the transplant waiting list and is currently the standard method used to assess severity in all etiologies of cirrhosis. Hepatocellular carcinoma (HCC) is the most common standard MELD exception because the MELD does not necessarily reflect the medical urgency of patients with HCC. The criteria for candidates with HCC for receiving LT have evolved over the past decade. Now, patients with HCC who do not meet the traditional Milan (MC) or UCSF criteria for LT often undergo downstaging therapy I an effort to shrink the tumor size. The shortage of donor organs is a universal problem. In some countries, the development of a deceased organ donation program has been prevented due to socioeconomic, cultural, legal and other factors. Due to the shortage of cadaveric donors, several innovative techniques have been developed to expand the organ donor pool, such as split liver grafts, marginal- or extended-criteria donors, live donor liver transplantation (LDLT), and the use

    Coffman, Kathy L; Siemionow, Maria Z

    2014-04-01

    There have been 26 cases of facial transplantation reported, and three deaths, 11.5%. Mortality raises the issue of risk versus benefit for face transplantation, a procedure intended to improve quality of life, rather than saving life. Thus, one of the most innovative surgical procedures has opened the debate on the ethical, legal, and philosophical aspects of face transplantation. Morbidity in face transplant recipients includes infections and metabolic consequences. No graft loss caused by technical failure, hyperacute, or chronic graft rejection or graft-versus-host disease has been reported. One case of posttransplant lymphoproliferative disorder, 3.45% and one case of lymphoma in an HIV-positive recipient were reported. Psychological issues in candidates can include chronic pain, mood disorders, preexisting psychotic disorders, post-traumatic stress disorder (PTSD), and substance abuse. Early publications on ethical aspects of face transplantation focused mainly on informed consent. Many other ethical issues have been identified, including lack of coercion, donor family consent and confidentiality, respect for the integrity of the donor's body, and financial promotion of the recipient and transplant team, as well as the cost to society for such a highly technical procedure, requiring lifelong immunosuppression.

    Chronic liver disease has a profound effect on nutritional status and undernourishment is almost universally present in patients with end-stage liver disease undergoing liver transplantation. In the last decades, due to epidemiological changes, a trend showing an increase in patients with end-stage liver disease and associated obesity has also been reported in developed countries. Nutrition abnormalities may influence the outcome after transplantation therefore, the importance to carefully assess the nutritional status in the work-up of patients candidates for liver transplantation is widely accepted. More attention has been given to malnourished patients as they represent the greater number. The subjective global nutritional assessment and anthropometric measurements are recognized in current guidelines to be adequate in identifying those patients at risk of malnutrition. Cirrhotic patients with a depletion in lean body mass and fat deposits have an increased surgical risk and malnutrition may impact on morbidity, mortality and costs in the post-transplantation setting. For this reason an adequate calorie and protein intake should always be ensured to malnourished cirrhotic patient either through the diet, or using oral nutritional supplements or by enteral or parenteral nutrition although studies supporting the efficacy of nutritional supplementation in improving the clinical outcomes after transplantation are still scarce. When liver function is restored, an amelioration in the nutritional status is expected. After liver transplantation in fact dietary intake rapidly normalizes and fat mass is progressively regained while the recovery of muscle mass can be slower. In some patients unregulated weight gain may lead to over-nutrition and may favor metabolic disorders (hypertension, hyperglycemia, hyperlipidemia). This condition, defined as 'metabolic syndrome', may play a negative role on the overall survival of liver transplant patients. In this report we review

    Full Text Available Organ transplantation has progressed tremendously with improvements in surgical methods, organ preservation, and pharmaco-immunologic therapies and has become a critical pathway in the management of severe organ failure worldwide. The major sources of organs are deceased donors after brain death; however, a substantial number of organs come from live donations, and a significant number can also be obtained from non-heart-beating donors. Yet, despite progress in medical, pharmacologic, and surgical techniques, the shortage of organs is a worldwide problem that needs to be addressed internationally at the highest possible levels. This particular field involves medical ethics, religion, and society behavior and beliefs. Some of the critical ethical issues that require aggressive interference are organ trafficking, payments for organs, and the delicate balance in live donations between the benefit to the recipient and the possible harm to the donor and others. A major issue in organ transplantation is the definition of death and particularly brain death. Another major critical factor is the internal tendency of a specific society to donate organs. In the review below, we will discuss the various challenges that face organ donation worldwide, and particularly in Israel, and some proposed mechanisms to overcome this difficulty.

    Full Text Available The goals of post-transplant management are to manage and treat postoperative complications, and develop a balanced long-term immunotherapy regimen that minimizes infection and side effects but controls rejection. While modern immunosuppressant regimes have reduced rates of graft loss due to rejection, they impart major risks for infection, growth failure, metabolic complications, and malignancy. There is significantly more post-transplant morbidity and mortality from infection than from rejection, particularly in infants. This has led to a trend toward minimization of immunosuppression, which is supported by evidence that some rejection facilitates graft tolerance and thus is not necessarily always harmful. Post-transplant complications are divided into those that occur in the first 3–12 months (“early”, and these are relatively common, and those occurring after 12 months (“late”, which are generally uncommon. Most “early” complications relate to surgical issues, and/or immunosuppression, most notably infection, vascular complications of the graft, and biliary leaks. Infection is the most common cause of post-transplant mortality. Rejection does occur but usually responds to treatment with steroid pulse dosing, and appears not to contribute to either graft or patient mortality. “Late” complications include biliary strictures, which are uncommon and generally respond to percutaneous biliary dilatation and stent procedures. Most late complications are primarily related to the effects of long-term immunosuppression, notably infections such as EBV and associated PTLD, and side effects of immunosuppression such as renal dysfunction, hypertension, and immune dysregulation.

    Full Text Available Transplantation is already the optimum treatment for terminal renal failure. Donor organ shortage means that there are large number of patients on dialysis awaiting this treatment. This has in some countries led to unacceptable unscrupulous practices of live non-related graft donation. The outcome of graft and patient after transplantation has improved significantly based on a better understanding of immunopathology, immunosuppression and tissue typing. The future is promising and xenografting may well solve the organ shortage but undoubtedly will raise other issues.

    Pancreas transplantation can be complicated by vascular thrombosis, stenosis, or anastomotic leak, complications that predispose to transplant pancreatectomy. The relative roles of noninvasive radiologic studies in such vascular complications have been correlated with angiographic or pathologic data. The results of 54 scintigraphic studies, 25 CT studies, 16 sonograms, and 23 color Doppler examinations have been correlated with those of 40 angiograms and 28 pathologic studies in a population of 185 recipients. CT (sensitivity, 100%; specificity, 75%; accuracy, 92%) and US (sensitivity, 88%; specificity, 80%; accuracy, 85%) were most helpful in noninvasive screening for vascular complications, while angiography remains nearly definite in the radiographic diagnosis of these problems

    2018-01-01

    Transplantation for adult patients with congenital heart disease (ACHD) is a growing clinical endeavor in the transplant community. Understanding the results and defining potential high-risk patient subsets will allow optimization of patient outcomes. This review summarizes the scope of ACHD transplantation, the mechanisms of late ventricular dysfunction, the ACHD population at risk of developing heart failure, the indications and potential contraindications for transplant, surgical considerations, and post-transplant outcomes. The findings reveal that 3.3% of adult heart transplants occur in ACHD patients. The potential mechanisms for the development of late ventricular dysfunction include a morphologic systemic right ventricle, altered coronary perfusion, and ventricular noncompaction. The indications for transplant in ACHD patients include systemic ventricular failure refractory medical therapy, Fontan patients failing from chronic passive pulmonary circulation, and progressive cyanosis leading to functional decline. Transplantation in ACHD patients can be quite complex and may require extensive reconstruction of the branch pulmonary arteries, systemic veins, or the aorta. Vasoplegia, bleeding, and graft right ventricular dysfunction can complicate the immediate post-transplant period. The post-transplant operative mortality ranges between 14% and 39%. The majority of early mortality occurs in ACHD patients with univentricular congenital heart disease. However, there has been improvement in operative survival in more contemporary studies. In conclusion, the experience with cardiac transplantation for ACHD patients with end-stage heart failure is growing, and high-risk patient subsets have been defined. Significant strides have been made in developing evidence-based guidelines of indications for transplant, and the intraoperative management of complex reconstruction has evolved. With proper patient selection, more aggressive use of mechanical circulatory support

The uterus transplantation procedure consisted of robot-assisted uterine procurement, orthotopic replacement and fixation of the retrieved uterus, revascularization, and end-to-side anastomoses of bilateral hypogastric arteries and ovarian-uterine vein to the bilateral external iliac arteries and veins. Data from preoperative investigations, surgery, and follow-up (12 months). The duration of the donor and recipient surgeries were 6 and 8 hours, 50 minutes, respectively. No immediate perioperative complications occurred in the recipient or donor. The recipient experienced menarche 40 days after transplant surgery, and she has had 12 menstrual cycles since the surgery. No rejection episodes occurred in the recipient. These results demonstrate the feasibility of live-donor uterine transplantation with a low-dose immunosuppressive protocol and the role of DaVinci robotic assistance during human uterine procurement.

    2001-04-01

    Reconstruction of the eyebrow has historically been accomplished with temporal scalp pedicle flap formation or free composite scalp grafts. These two techniques may be associated with substantial morbidity and a false, overly dense eyebrow appearance. Hair transplantation of the eyebrows has been described with excellent results, but is relatively underreported in the literature. To determine whether modern techniques of micrograft hair transplantation can suitably re-create an aesthetic eyebrow in a case of iatrogenic eyebrow alopecia. A 33-year-old woman with iatrogenic eyebrow alopecia underwent four sessions of eyebrow micrograft hair transplantation to re-create both eyebrows. Suitable aesthetic eyebrows were re-created in a symmetric fashion with proper hair orientation. The process was time consuming and tedious, but highly effective. Eyebrow transplantation is a suitable alternative to pedicle flap formation and composite scalp grafting. It is a straightforward procedure that can be performed in the office under local anesthesia with minimal attendant morbidity. The result may be superior to that seen with more involved eyebrow replacement procedures.

    Full Text Available Introduction: Kidney transplantation (KT has traditionally been performed by open renal transplantation, but recently, a few groups including our own have described a minimally invasive approach to KT. We aim to discuss the current status of robotic kidney transplantation (RKT and describe our technique of RKT with regional hypothermia. Material and Methods: We used the search terms "minimally invasive" OR "robotic" OR "robot assisted" AND "kidney transplantation." Papers written in English and concerning technical and/or clinical outcomes following minimally invasive kidney transplantation were selected. Three hundred and eighteen unique articles were retrieved and nine were relevant. Comparative outcomes data following RKT with regional hypothermia versus open KT (OKT from our own group were also included. Findings: Nine papers, so far, have evaluated the role of robotic approach in KT and have conclusively established the feasibility, safety, and reproducibility of RKT, although these studies have been performed by experienced robotic surgeons/teams. The contemporary published series note that rejection rates were similar in RKT and OKT patients. Mean serum creatinine at 6 months in RKT and OKT patients was equivalent, across the three series. Most of the studies also note a dramatic reduction in the wound-related complication rates. Conclusion: RKT appears to be a safe surgical alternative to the standard open approach of KT. RKT is associated with reduced postoperative pain, analgesic requirement, and better cosmesis. RKT, although in its infancy, appears to be associated with lower complication rates.

    2016-11-01

    The aim of this study was to review and discuss the great variety of ethical issues related to organ donation, organ procurement, transplant activities, and new ethical problems created as a result of technologic and scientific developments. An extensive literature survey was made, and expert opinions were obtained. The gap between demand and supply of organs for transplant has yielded to organ trafficking, organ tourism, and commercialism. This problem seems to be the most important issue, and naturally there are ethical dilemmas related to it. A wide number of ideas have been expressed on the subject, and different solutions have been proposed. The struggle against organ trafficking and commercialism should include legislation, efforts to increase deceased-donor donations, and international cooperation. China's policy to procure organs from prisoners sentenced to death is unethical, and the international community should exert more pressure on the Chinese government to cease this practice. Each particular ethical dilemma should be taken separately and managed.

  18. A brief history of corneal transplantation: From ancient to modern

    Full Text Available This review highlights many of the fundamental concepts and events in the development of corneal transplantation - from ancient times to modern. Tales of eye, limb, and even heart transplantation appear in ancient and medieval texts; however, in the scientific sense, the original concepts of corneal surgery date back to the Greek physician Galen (130-200 AD. Although proposals to provide improved corneal clarity by surgical interventions, including keratoprostheses, were better developed by the 17 th and 18 th centuries, true scientific and surgical experimentation in this field did not begin until the 19 th century. Indeed, the success of contemporary corneal transplantation is largely the result of a culmination of pivotal ideas, experimentation, and perseverance by inspired individuals over the last 200 years. Franz Reisinger initiated experimental animal corneal transplantation in 1818, coining the term "keratoplasty". Subsequently, Wilhelmus Thorne created the term corneal transplant and 3 years later Samuel Bigger, 1837, reported successful corneal transplantation in a gazelle. The first recorded therapeutic corneal xenograft on a human was reported shortly thereafter in 1838-unsurprisingly this was unsuccessful. Further progress in corneal transplantation was significantly hindered by limited understanding of antiseptic principles, anesthesiology, surgical technique, and immunology. There ensued an extremely prolonged period of debate and experimentation upon the utility of animal compared to human tissue, and lamellar versus penetrating keratoplasty. Indeed, the first successful human corneal transplant was not performed by Eduard Zirm until 1905. Since that first successful corneal transplant, innumerable ophthalmologists have contributed to the development and refinement of corneal transplantation aided by the development of surgical microscopes, refined suture materials, the development of eye banks, and the introduction of

    2004-01-01

    Full Text Available The past two decades have witnessed remarkable progress in limbal stem cell transplantation. In addition to harvesting stem cells from a cadaver or a live related donor, it is now possible to cultivate limbal stem cells in vitro and then transplant them onto the recipient bed. A clear understanding of the basic disease pathology and a correct assessment of the extent of stem cell deficiency are essential. A holistic approach towards management of limbal stem cell deficiency is needed. This also includes management of the underlying systemic disease, ocular adnexal pathology and dry eye. Conjunctival limbal autografts from the healthy contralateral eye are performed for unilateral cases. In bilateral cases, tissue may be harvested from a cadaver or a living related donor; prolonged immunosuppression is needed to avoid allograft rejection in such cases. This review describes the surgical techniques, postoperative treatment regimes (including immunosuppression for allografts, the complications and their management. The short and long-term outcomes of the various modalities reported in the literature are also described.

    Severely disfiguring facial injuries can have a devastating impact on the patient's quality of life. During the past decade, vascularized facial allotransplantation has progressed from an experimental possibility to a clinical reality in the fields of disease, trauma, and congenital malformations. This technique may now be considered a viable option for repairing complex craniofacial defects for which the results of autologous reconstruction remain suboptimal. Vascularized facial allotransplantation permits optimal anatomical reconstruction and provides desired functional, esthetic, and psychosocial benefits that are far superior to those achieved with conventional methods. Along with dramatic improvements in their functional statuses, patients regain the ability to make facial expressions such as smiling and to perform various functions such as smelling, eating, drinking, and speaking. The ideas in the 1997 movie "Face/Off" have now been realized in the clinical field. The objective of this article is to introduce this new surgical field, provide a basis for examining the status of the field of face transplantation, and stimulate and enhance facial transplantation studies in Korea.

Since then the field of transplantation has seen remarkable advancements in both surgical techniques and our understanding and ability to manipulate the immune response. Composite tissue allotransplantation involves the transplantation of any combination of vascularized skin, subcutaneous tissue, blood vessels, nerves, muscle, and bone. Orthotopic hand transplantation is considered the first clinical example of CTA and has seen success at many different centers worldwide. Facial allotransplantation is a recent development in the field of CTA and the first successful case was performed as recently as November 2005. Since then there have been a number of successful facial transplants. The purpose of this paper is to examine some of the issues surrounding facial transplantation including the complex ethical issues, the surgical and clinical issues, cost and administrative issues, and future directions for this new, exciting, and controversial field.Keywords: composite tissue allograft, facial transplantation

    Lung transplantation recipients are at an increased risk for developing diverticulitis. However, the incidence and natural history of diverticulitis have not been well characterized. Our objective was to identify patient and transplant-related factors that may be associated with an increased risk of developing diverticulitis in this patient population. This is a retrospective single institution study. All patients who received a lung transplant between May 2008 and July 2013 were evaluated using an existing lung transplantation database. Patient-related factors, the incidence and timing of diverticulitis, and outcomes of medical and surgical management were measured. Of the 314 patients who received a lung transplant, 14 patients (4.5%) developed diverticulitis. All episodes (100%) of diverticulitis occurred within the first 2 y after transplantation. Eight patients (57%) required surgery with a mortality rate of 12.5%. Six patients (43%) were managed medically and did not require surgery with a mean follow-up period of 442 d. Diverticulitis is common after lung transplantation and occurs with a higher incidence compared with the general population. Diverticulitis occurs early in the posttransplant period, and the majority of patients require surgery. Patients who respond promptly to medical treatment may not require elective resection. A greater awareness of the risk of diverticulitis in the early posttransplant period may allow for earlier diagnosis and treatment. Copyright © 2014 Elsevier Inc. All rights reserved.

    Background Renal replacement therapy was first introduced in Yemen in 1978 in the form of hemodialysis. Twenty years later, the first renal transplantation was performed. Kidney transplantations were started in socially and financially challenging circumstances in Yemen in 1998. A structured program was established and has been functioning regularly since 2005. A pediatric transplantation program was started in 2011. Material and Methods This was a prospective study of 181 transplants performed at the Urology and Nephrology Center between May 1998 and 2012. All transplants were from living related donors. The immunosuppressive protocol consisted initially of double therapy with steroid and mycophenolate mofetil (MMF). Subsequently, triple therapy with addition of a calcineurin inhibitor was introduced. Primary graft function was achieved in 176 (97.2%) recipients. Results Cold ischemia time was 48-68 min. Episodes of acute rejection in 12 patients were treated with high-dose steroids. Anti-thymocyte globulin (ATG) was used in cases of vascular or steroid-resistant rejection in 2 patients. The post-transplant complications, either surgical or medical, were comparable to those recorded in the literature. Conclusions Renal transplantation is a good achievement in our country. The patients and graft survival rates are comparable to other reports.

    Advances in treatment of androgenetic alopecia have led to the development of novel medical or surgical therapies adapted to the severity of hair loss and balding. Follicular units or tiny micro-graft hair transplants are a fundamental technical progress. This technique leads to the simple and painless permanent restoration of hair in male and female baldness. It provides the patient with a group of 1 to 3 hairs, emerging from a single orifice. The difference between androgenic receptors of occipital areas and those of other areas explains the permanent nature of the implanted hair growth. The degree of male or female androgenetic alopecia can be determined according to Hamilton's static classification or Ludwig's Classification, or it can be measured and monitored more accurately with Bouhanna's Dynamic Multifactorial Classification. The current indications for micro-graft transplantation are

    The involvement of healthy living donors and the degree of technical difficulty make adult living donor liver transplantation (LDLT) different from any other surgical procedure. We surveyed 100 liver transplant surgeons to assess their views on the complex issues raised by LDLT. Data were collected at meetings on LDLT and by electronic mail. The study instrument was divided into general, donor, surgeon, recipient, and donor and recipient issues. Subjects provided the projected 1-year survival threshold that they would require for the recipient before they would perform LDLT. They listed the three topics that they thought were most critical for transplant fellows to know about LDLT. A majority agreed that transplant programs have a duty to their patients to offer LDLT, that the increasing success of the procedure will expand indications for liver transplantation, and that the risk to the donor causes them a moral dilemma. There was more divergence of opinion regarding who should have the final say about a potential donor's candidacy, whether it is difficult for donors to comprehend the risks of the procedure, and whether repeat cadaveric transplantations should be offered for failed LDLT performed for extended indications. Surgeons' median recipient survival threshold was a conservative 79%. Priorities for educating trainees focused on understanding complications and risks, technical factors, and ethical concerns such as putting the donor first. In conclusion, the findings of this survey indicate that transplant surgeons are working to balance their moral imperative to provide life-saving therapy for transplantation candidates with the risks posed to living donors.

    Increased cancer incidence, particularly lymphoproliferative disease, is a complication of immunosuppression in organ transplantation. Non-Hodgkin's lymphomas (NHLs) occur frequently during the first year after transplantation, more so in North America than in Europe. This study audited and correlated the demographic, clinical, pathological, and outcome features of post-transplant lymphoproliferative disorders (PTLDs) in a large centre in Oxford, and assessed whether the time of onset fitted more with the European or North American pattern. There were 1383 renal transplants in the study period and 27 patients developed lymphoma: 26 NHLs and one Hodgkin's disease (1.95%). Four of the patients never received cyclosporin. The mean time of diagnosis after transplant was 46 months. Most tumours (21/27) presented extranodally. Management included reduction of immunosuppression, surgical excision, antiviral treatment, radiotherapy, and chemotherapy. Three patients presented in the first post-transplant year-0.34% of cyclosporin managed patients-similar to the North American incidence, although the incidence of extranodal late PTLDs was also high (mean onset, 36 months v 15 months international mean). Post-transplant lymphomas were the most common malignancy associated with death in transplant patients. PTLDs occurred in 2% of renal transplant patients, presenting both in the first year in association with cyclosporin use, as in North America, but also in subsequent years, giving an overall presentation time later than the international mean. The disease usually presented extranodally, accounting for the wide range of symptoms and signs. Despite awareness and active management, the disease contributed to death in more that 50% of patients with PTLDs.

    Over 26 years, we found 46 infectious episodes in 350 kidney transplant recipients. Fifteen were urinary tract infections, recurrent in 4 patients. There were 8 cytomegalovirus infections, three of them fatal when intravenous (IV) ganciclovir was not available. Seven patients had a reactivation of tuberculosis (TB) in the pleura, cervical spine, lumbar spine, knee, ankle, skin and peritoneum, respectively, and were all resolved satisfactorily with conventional anti-TB therapy. Three patients transplanted before routine prophylaxis with the use of acyclovir developed an extensive herpes zoster infection in the 1st 6 months after transplantation, which was resolved with the use of oral acyclovir, and 1 had a disseminated herpes simplex infection resolved with the use of IV acyclovir. Three patients transplanted before routine prophylaxis with trimethoprim sulfa developed Pneumocystis carinii pneumonia in the 1st 6 months after transplantation, which was fatal in one of them. In 2 patients, we found a Nocardia infection, confined to the lung, which was cured in one of the cases and systemic and fatal in the other. Two patients transplanted before routine prophylaxis with the use of nystatin developed esophageal candidiasis in the 1st 6 months after transplantation. One patient developed infective endocarditis in a stenotic bicuspid aortic valve and died 10 years later after another incident of infective endocarditis at the prosthetic aortic valve. Two patients developed an extensive condyloma at the penis, perianal region, and perineum owing to human papillomavirus, requiring extensive surgical resection and podophyllin applications. Another patient developed fatal post-transplantation lymphoproliferative disease due to Epstein-Barr virus infection 15 years after transplantation. One patient developed a severe and fatal mucocutaneous leishmaniasis with no response to conventional antimonial therapy. It is interesting to note that despite Chagas disease being endemic

    To review epidemiologic data's and medical results of deceased donation in renal transplantation. Relevant publications were identified through Medline (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) database using the following keywords, alone or in association, "brain death; cardiac arrest; deceased donation; organ procurement; transplantation". Articles were selected according to methods, language of publication and relevance. The reference lists were used to identify additional historical studies of interest. Both prospective and retrospective series, in French and English, as well as review articles and recommendations were selected. In addition, French national transplant and health agencies (http://www.agence-biomedecine.fr and http://www.has-sante.fr) databases were screened using identical keywords. A total of 2498 articles, 8 official reports and 17 newspaper articles were identified; after careful selection 157 publications were eligible for our review. Deceased donation may involve either brain death or non-heartbeating donors (NHBD). Organ shortage led to the procurement of organs from expanded-criteria donors, with an increased age at donation and extended vascular disease, leading to inferior results after transplantation and underlining the need for careful donor management during brain death or cardiac arrest. Evolution of French legislation covering bioethics allowed procurement from Maastricht categories II and recently III non-heartbeating donors. The increase of organ shortage emphasizes the need for a rigorous surgical technique during procurement to avoid loss of transplants. A history or current neoplasm in deceased-donors, requires attention to increase the pool of organs without putting the recipients at risk for cancer transmission. French NHBD program, especially from Maastricht category III, may stand for a potential source of valuable organs. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    The techniques derived from abdominal transplant surgery have become a major actor in recent surgical evolution by providing a more optimal solution for urologic malignancies hosted in the upper abdomen. To describe in detail the objectives, rationale, relevant milestones, and surgical maneuvers of the so-called transplant techniques as applied to complex urologic oncology cases. The transplant-based surgical approach aims to decrease perioperative complications by improving tumor accessibility and field visibility through an enhanced exposure (via the use of a transverse incision, a specific retractor, and specific surgical maneuvers). A sequence of milestones inspired these advances, which finally brought the technique into maturation. The transplant-based approach has demonstrated its safety and usefulness even in the low-volume practice of more complicated urologic oncology, offering protection against the occurrence of perioperative adverse events and placing us at the gates of a new stage of surgical innovation.

    To overcome the shortage of appropriate-sized whole liver grafts for children, technical variant liver transplantation has been practiced for decades. We perform a meta-analysis to compare the survival rates and incidence of surgical complications between pediatric whole liver transplantation and technical variant liver transplantation. To identify relevant studies up to January 2014, we searched PubMed/Medline, Embase, and Cochrane library databases. The primary outcomes measured were patient and graft survival rates, and the secondary outcomes were the incidence of surgical complications. The outcomes were pooled using a fixed-effects model or random-effects model. The one-year, three-year, five-year patient survival rates and one-year, three-year graft survival rates were significantly higher in whole liver transplantation than technical variant liver transplantation (OR = 1.62, 1.90, 1.65, 1.78, and 1.62, respectively, ptechnical variant liver transplantation. Continuing efforts should be made to minimize surgical complications to improve the outcomes of technical variant liver transplantation.

    To describe our experience of pediatric living donor liver transplantation from India over a period of 12 years. A retrospective analysis of 200 living donor liver transplantation in children (18 years or younger) was done for demographic features, indications, donor and graft profile and outcome. Between September 2004 and July 2016, 200 liver transplants were performed on 197 children. Fifty transplants were done in initial 6 years and 150 in next 6 years. All donors (51% mothers) were discharged with a mean stay of 7 days. The leading indications of liver transplants were cholestatic liver disease (46%) followed by metabolic liver disease (33%) and acute liver failure/acute on chronic liver failure (28.5%). Biliary leakage (8.5%), biliary stricture (9%), hepatic artery thrombosis (4.5%) and portal vein thrombosis (4%) were the most common surgical complications; all could be managed by surgical or interventional radiological measures, except in one child who died. Sepsis, acute rejection and CMV hepatitis in first 6 months were seen in 14.5%, 25% and 17% cases, respectively. Post-transplant lymphoproliferative disease was seen in only 1.5%. Re-transplant rate was 1.5%. The overall 1 year survival rate was 94% and 5 year actuarial survival was 87% with no statistically significant difference between children weight 10 kg. Outcome in acute liver failure did not differ significantly between those with acute on chronic liver failure vs. those with chronic liver disease. Advances in medical and surgical techniques associated with multidisciplinary teams including skilled pediatric liver transplant surgeons, anesthetists, dedicated pediatric hepatologists, pediatric intensivists, interventional radiologists and pathologists resulted in an excellent outcome of living related liver transplants in children. Low age and weight of the baby does not seem to be a contraindication for liver transplantation as outcome were comparable in our experience.

    Kidney transplants were first performed in Tunisia in 1986, and transplants soon extended to other organs including the heart, liver, and pancreas. Live-related donor and deceased-donor kidney transplants were both began in the summer of 1986. An organ procurement and transplant law was passed in March 1991, and the National Centre for Advancement of Organ Transplantation was created in 1995. The number of transplantation units has increased to 7 throughout the country, and the yearly transplant number has progressively increased to 139 in 2010, including 20% from deceased kidney donors. Despite these gains, the need continues to grow. Heart transplants began in January 1993, and Tunisia and Jordan are currently the only Arab countries where it is practiced. However, only 16 patients have received a heart transplant as of 2004, and the number of recipients has decreased in the past 10 years. Liver transplants are rare in other Arab countries, but began in Tunisia in January 1998. Over 10 years, 38 patients benefited from this procedure. After a few years of stagnation, the number of liver transplants is increasing. While all types of transplantation are needed, kidney transplantation is a priority in Tunisia. The target is to perform 400 transplants annually, which would require a long-term strategy to provide full financial coverage using the National Health Insurance Funds in both the public and private sectors.

    Appendicitis is a common cause of emergency surgery that in the population undergoing organ transplantation presents a rare incidence due to late diagnosis and treatment. To report the occurrence of acute appendicitis in a cohort of liver transplant recipients. Retrospective analysis in a period of 12 years among 925 liver transplants, in witch five cases of acute appendicitis were encountered. Appendicitis occurred between three and 46 months after liver transplantation. The age ranged between 15 and 58 years. There were three men and two women. The clinical presentations varied, but not discordant from those found in non-transplanted patients. Pain was a symptom found in all patients, in two cases well located in the right iliac fossa (40%). Two patients had symptoms characteristic of peritoneal irritation (40%) and one patient had abdominal distention (20%). All patients were submitted to laparotomies. In 20% there were no complications. In 80% was performed appendectomy complicated by suppuration (40%) or perforation (40%). Superficial infection of the surgical site occurred in two patients, requiring clinical management. The hospital stay ranged from 48 h to 45 days. Acute appendicitis after liver transplantation is a rare event being associated with a high rate of drilling, due to delays in diagnosis and therapy, and an increase in hospital stay.

  18. The Global Role of Kidney Transplantation

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available World Kidney Day on March 8 th 2012 provides a chance to reflect on the success of kidney transplantation as a therapy for end stage kidney disease that surpasses dialysis treatments both for the quality and quantity of life that it provides and for its cost effectiveness. Anything that is both cheaper and better, but is not actually the dominant therapy, must have other drawbacks that prevent replacement of all dialysis treatment by transplantation. The barriers to universal transplantation as the therapy for end stage kidney disease include the economic limitations which, in some countries place transplantation, appropriately, at a lower priority than public health fundamentals such as clean water, sanitation and vaccination. Even in high income countries the technical challenges of surgery and the consequences of immunosuppression restrict the number of suitable recipients, but the major finite restrictions on kidney transplantation rates are the shortage of donated organs and the limited medical, surgical and nursing workforces with the required expertise. These problems have solutions which involve the full range of societal, professional, governmental and political environments. World Kidney Day is a call to deliver transplantation therapy to the one million people a year who have a right to benefit.

    Full Text Available Background. The challenge in managing patients undergoing renal transplantation is how to achieve optimum levels of anticoagulation to avoid both clotting and postoperative bleeding. We report a rare case of severe postoperative retroperitoneal bleeding including psoas haematomata complicating renal transplantation. Case Report. SM, a 55-year-old female, had a past history of aortic valve replacement, cerebrovascular event, and thoracic aortic aneurysm and was on long-term warfarin that was switched to enoxaparin 60 mg daily a week prior to her living donor transplantation. Postoperatively, she was started on a heparin infusion, but this was complicated by a large retroperitoneal bleed requiring surgical evacuation on the first postoperative day. Four weeks later, she developed features compatible with acute femoral neuropathy and a CT scan revealed bilateral psoas haematomata. Following conservative management, she made steady progress and was discharged home via a community hospital 94 days after transplantation. At her last visit 18 months after transplantation, she had returned to full fitness with excellent transplant function. Conclusion. Patients in established renal failure who require significant anticoagulation are at increased risk of bleeding that may involve prolonged hospitalisation and more protracted recovery and patients should be carefully counselled about this.

    Full Text Available Hair transplantation is a surgical method of hair restoration. Physician qualification : The physician performing hair transplantation should have completed post graduation training in dermatology; he should have adequate background training in dermatosurgery at a centre that provides education training in cutaneous surgery. In addition, he should obtain specific hair transplantation training or experience at the surgical table(hands on under the supervision of an appropriately trained and experienced hair transplant surgeon. In addition to the surgical technique, training should include instruction in local anesthesia and emergency resuscitation and care. Facility : Hair transplantation can be performed safely in an outpatient day case dermatosurgical facility. The day case theatre should be equipped with facilities for monitoring and handling emergencies. A plan for handling emergencies should be in place and all nursing staff should be familiar with the emergency plan. It is preferable, but not mandatory to have a standby anesthetist. Indication for hair transplantation is pattern hair loss in males and also in females. In female pattern hair loss, investigations to rule out any underlying cause for hair loss such as anemia and thyroid deficiency should be carried out. Hair transplantation can also be performed in selected cases of scarring alopecia, eyebrows and eye lashes, by experienced surgeons. Preoperative counseling and informed consent :Detailed consent form listing details about the procedure and possible complications should be signed by the patient. The consent form should specifically state the limitations of the procedure and if more procedures are needed for proper results, it should be clearly mentioned. Patient should be provided with adequate opportunity to seek information through brochures, computer presentations, and personal discussions. Need for concomitant medical therapy should be emphasized. Patients should understand

    CT evaluation of the abdomen and pelvis is of great value after pancreatic transplantation. The expected CT appearance after pancreas transportation with both enteric and bladder drainage of exocrine function are presented, as is the appearance of infected and ischemic grafts. The CT detection and CT- and US-guided percutaneous aspiration and drainage of abdominal fluid collections are described. At the authors' institution, such aspiration and drainage procedures have obviated transplant pancreatectomy or surgical abscess drainage in 29% of patients

    Kidney transplantation is the best approach for treating patients with end stage renal disease, offering patients the best chance of returning to normal health. While the techniques used in kidney transplantation surgery are mature and highly successful, there is a severe shortage of donor organs. Statistics show a serious imbalance between organ donations and patients on the waiting list for organ transplantation. Moreover, evidence from empirical studies has shown a better transplantation outcome for patients who receive living donor transplantation than for those who receive organs from cadavers. Although using relatives as donors offers an effective way to reduce the problem of organ shortage, this strategy faces many challenges and many other factors affect the promotion of living donor transplantation. This article elaborates how cultural and psychological factors, kidney transplantation awareness, and ethics and laws impact upon living kidney donations and then proposes coping strategies for promoting living kidney transplantation.

    The Republic of Kazakhstan is one of the fastest developing countries in the world and has a health care system that is unique in Central Asia. Its organ transplant services are also developing rapidly. We aimed to analyze and briefly report on the current status of organ transplant in the Republic of Kazakhstan. We analyzed organ transplant activities in that country for the period 2012 to 2014. All data were collected from the official database of the National Transplant Coordinating Center of the Republic of Kazakhstan. At the end of 2014, the number of transplant centers had increased to 10, three of which could perform multiorgan transplants; during the same period, the number of deceased-donor organ-donating hospitals increased up to 37. By 2013, the transplant activity rate for all centers had reached 9.22 per million population. During the previous 3 years (2012-2014), there was a 3-fold increase in the number of living donors and an 18-fold increase in the number of kidney transplants. Between 2012 and 2014, the number of living-donor liver transplants increased from 17 to 25, and the number of deceased-donor transplants increased from 3 to 7. During the last 3 years (2012-2014), the number of heart transplants increased to 7 cases. During the last 3 years (2012-2014), Kazakhstan achieved a significant improvement in the organization of its transplant services, and a noticeable upward trend in the system continues.

    Telesforo Bacchella

    Full Text Available CONTEXT AND OBJECTIVE: Expanded donor criteria (marginal grafts are an important solution for organ shortage. Nevertheless, they raise an ethical dilemma because they may increase the risk of transplant failure. This study compares the outcomes from marginal and non-marginal graft transplantation in 103 cases of liver transplantation due to chronic hepatic failure. DESIGN AND SETTING: One hundred and three consecutive liver transplantations to treat chronic liver disease performed in the Liver Transplantation Service of Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo between January 2001 and March 2006 were retrospectively analyzed. METHODS: We estimated graft quality according to a validated scoring system. We assessed the pre-transplantation liver disease category using the Model for End-Stage Liver Disease (MELD, as low MELD ( 20. The parameters for marginal and non-marginal graft comparison were the one-week, one-month and one-year recipient survival rates, serum liver enzyme peak, post-transplantation hospital stay and incidence of surgical complications and retransplantation. The significance level was 0.05. RESULTS: There were no differences between the groups regarding post-transplantation hospital stay, serum liver enzyme levels and surgical complications. In contrast, marginal grafts decreased overall recipient survival one month after transplantation. Furthermore, low-MELD recipients of non-marginal grafts showed better one-week and one-month survival than did high-MELD recipients of marginal livers. After the first month, patient survival was comparable in all groups up to one year. CONCLUSION: The use of marginal graft increases early mortality in liver transplantation, particularly among high-MELD recipients.

    Full Text Available Objectives: This study sought to report 22 years experience in pediatric kidney transplantation in Oman. Methods: Electronic charts of all Omani children below 13 years of age who received a kidney transplant from January 1994 to December 2015 were reviewed. Data collected included patient demographics, etiology of end-stage kidney disease, modality and duration of dialysis, donor type, complication of kidney transplantation (including surgical complications, infections, graft rejection graft and patient survival, and duration of follow-up. Results: During the study period transplantation from 27 living related donors (LRDs, 42 living unrelated donors (LURDs, also referred to as commercial transplant, and one deceased donor were performed. The median age at transplantation was nine years for both groups. The most common primary diagnosis was congenital anomalies of the kidney and urinary tract in 32.8% of patients followed by familial nephrotic syndrome in 20.0% and polycystic kidney disease in 18.5%. Almost half the patients were on hemodialysis before transplantation, 35.7% were on peritoneal dialysis, and 14.2% received preemptive renal transplantation. Children who received LURD kidneys had high surgical complications (42.8% compared to the LRDs group (17.8%. Five patients from LURDs group had early graft nephrectomy and four patients developed non-graft function or delayed graft function. In addition, patients in the LURDs group had a higher incidence of hypertension and acute rejection. Graft and patient survival were both better in the LRDs than the LURDs group. Conclusions: Although our pediatric kidney transplant program is a young program it has had successful patient outcomes comparable to international programs. Our study provides evidence that in addition to legal and ethical issues with commercial transplant, it also carries significantly higher morbidity and reduced graft and patient survival.

    Excellent outcomes over the last 3 decades have made liver transplantation the treatment of choice for many advanced liver disorders. This success also opened liver transplantation to new indications such as liver tumors and metabolic disorders. The emergence of such new indications for liver transplantation is bringing a new stream of patients along with disease-specific challenges. The cumulative number of liver transplant recipients is peaking, requiring novel systems of health care delivery that meet the needs of this special patient population.

    Hepatoblastoma is the most common primary malignant liver tumor in children and is usually diagnosed during the first 3 years of life. Overall survival has increased 50% due to chemotherapeutic schemes, expertise surgery centers, and liver transplantation. A retrospective collection of data was performed from pediatric patients with diagnosis of hepatoblastoma. Variables included demographic, diagnostic tools and histological classification; chemotherapy and surgical treatment; and outcomes and patient survival. The PRETEXT classification was applied, which included the risk evaluation, and according to the medical criterion in an individualized way, underwent resection or transplant. The morbidity of patients was evaluated by the Clavien-Dindo classification. Statistical analysis was performed according to the distribution of data and the survival analysis was carried out using the Kaplan-Meier method. The patients (n = 16) were divided in a resection group (n = 8) and a transplant group (n = 8). The median age at the time of diagnosis was 13.5 months. The motive for the initial consultation was the discovery of a mass; all patients had high levels of α-fetoprotein and an imaging study. Ten of 16 patients required chemotherapy before the surgical procedure. In the resection group, 5 of 8 patients were classified as Clavien I and 4 of 8 patients of the transplant group were classified as Clavien II. Patient survival at 30 months was 100% in the resection group and 65% in the liver transplantation group. To our knowledge, this is the first case report of pediatric patients with hepatoblastoma and liver resection or transplant in Colombia and Latin America. Our results are comparable with the series worldwide, showing that resection and transplant increase the survival of the pediatric patients with hepatoblastoma. It is important to advocate for an increase of reporting in the scientific literature in Latin America.

    Root canal treatment usually fails because infection remains within the root canal. An orthograde attempt at re-treatment should always be considered first. However, when surgery is indicated, modern microtechniques coupled with surgical magnification will lead to a better prognosis. Careful management of the hard and soft tissues is essential, specially designed ultrasonic tips should be used for root end preparation which should ideally be sealed with MTA. All cases should be followed up until healing is seen, or failure accepted, and should form a part of clinical audit.

    Chronic liver disease has an important effect on nutritional status, and malnourishment is almost universally present in patients with end-stage liver disease who undergo liver transplantation. During recent decades, a trend has been reported that shows an increase in number of patients with end-stage liver disease and obesity in developed countries. The importance of carefully assessing the nutritional status during the work-up of patients who are candidates for liver replacement is widely recognised. Cirrhotic patients with depleted lean body mass (sarcopenia) and fat deposits have an increased surgical risk; malnutrition may further impact morbidity, mortality and costs in the post-transplantation setting. After transplantation and liver function is restored, many metabolic alterations are corrected, dietary intake is progressively normalised, and lifestyle changes may improve physical activity. Few studies have examined the modifications in body composition that occur in liver recipients. During the first 12 mo, the fat mass progressively increases in those patients who had previously depleted body mass, and the muscle mass recovery is subtle and non-significant by the end of the first year. In some patients, unregulated weight gain may lead to obesity and may promote metabolic disorders in the long term. Careful monitoring of nutritional changes will help identify the patients who are at risk for malnutrition or over-weight after liver transplantation. Physical and nutritional interventions must be investigated to evaluate their potential beneficial effect on body composition and muscle function after liver transplantation.

    Liver transplant is considered to be the last-resort treatment approach for pediatric patients with end-stage liver disease. Despite the remarkable advance in survival rates, liver transplant remains an intricate surgery with significant morbidity and mortality. Early diagnosis of complications is crucial for patient survival but is challenging given the lack of specificity in clinical presentation. Knowledge of the liver and vascular anatomy of the donor and the recipient or recipients before surgery is also important to avoid complications. In this framework, radiologists play a pivotal role on the multidisciplinary team in both pre- and postoperative scenarios by providing a road map to guide the surgery and by assisting in diagnosis of complications. The most common complications after liver transplant are (a) vascular, including the hepatic artery, portal vein, hepatic veins, and inferior vena cava; (b) biliary; (c) parenchymal; (d) perihepatic; and (e) neoplastic. The authors review surgical techniques, the role of each imaging modality, normal posttransplant imaging features, types of complications after liver transplant, and information required in the radiology report that is critical to patient care. They present an algorithm for an imaging approach for pediatric patients after liver transplant and describe key points that should be included in radiologic reports in the pre- and postoperative settings.

    Full Text Available The article (the second of five reviews the beginning of the Third Chapter from the monograph by V.P.Demikhov "Transplantation of vital organs in the experiment" (M.: Medgiz Publisher, 1960, the chapter covering the issue of homoplastic organ transplantation. The article discusses the results of V.P. Demikhov's work to create the following models: an additional isolated heart, an additional heart with a lung lobe, and a heart in combination with both lungs. Basing on the generally accepted "critical" timing of grafted transplant rejection onset (7th, 14th, or 21th days, Demikhov regarded the graft survival for longer as the fact of the successful engraftment, and every prolongation of the recipient's life with the donor organ as the win over the nature convinced him of the right path chosen. V.P. Demikhov performed the transplantation of the "heart-lungs" complex to simplify the separate anatomical transplantation of these organs and believed that the improvement of surgical methodology and techniques would enable him to achieve their complete engraftment, aiming at further translation the most successful experimental results from the laboratory into the clinical practice.

    2016-12-01

    Heart failure (HF) in adult congenital heart disease (ACHD) is vastly different to that observed in acquired heart disease. Unlike acquired HF in which pharmacological strategies are the cornerstone for protecting and improving ventricular function, ACHD-related HF relies heavily upon structural and other interventions to achieve these aims. patients with ACHD constitute a small percentage of the total adult heart transplant population (∼3%), although the number of ACHD heart transplant recipients is growing rapidly with a 40% increase over the last two decades. The worldwide experience to date has confirmed heart transplantation as an effective life-extending treatment option in carefully selected patients with ACHD with end-stage cardiac disease. Opportunities for improving outcomes in patients with ACHD-related HF include (i) earlier recognition and referral to centres with combined expertise in ACHD and HF, (ii) increased awareness of arrhythmia and sudden cardiac death risk in this population, (iii) greater collaboration between HF and ACHD specialists at the time of heart transplant assessment, (iv) expert surgical planning to reduce ischaemic time and bleeding risk at the time of transplant, (v) tailored immunosuppression in the post-transplant period and (vi) development and validation of ACHD-specific risk scores to predict mortality and guide patient selection. The purpose of this article is to review current approaches to diagnosing and treating advanced HF in patients with ACHD including indications, contraindications and clinical outcomes after heart transplantation.

    2009-06-01

    Full Text Available OBJECTIVE: The purpose of this study was to compare spirometry data between patients who underwent single-lung or double-lung transplantation the first year after transplantation. INTRODUCTION: Lung transplantation, which was initially described as an experimental method in 1963, has become a therapeutic option for patients with advanced pulmonary diseases due to improvements in organ conservation, surgical technique, immunosuppressive therapy and treatment of post-operative infections. METHODS: We retrospectively reviewed the records of the 39 patients who received lung transplantation in our institution between August 2003 and August 2006. Twenty-nine patients survived one year post-transplantation, and all of them were followed. RESULTS: The increase in lung function in the double-lung transplant group was more substantial than that of the single-lung transplant group, exhibiting a statistical difference from the 1st month in both the forced expiratory volume in one second (FEV1 and the forced vital capacity (FVC in comparison to the pre-transplant values (p <0.05. Comparison between double-lung transplant and single lung-transplant groups of emphysema patients demonstrated a significant difference in lung function beginning in the 3rd month after transplantation. DISCUSSION: The analyses of the whole group of transplant recipients and the sub-group of emphysema patients suggest the superiority of bilateral transplant over the unilateral alternative. Although the pre-transplant values of lung function were worse in the double-lung group, this difference was no longer significant in the subsequent months after surgery. CONCLUSION: Although both groups demonstrated functional improvement after transplantation, there was a clear tendency to greater improvement in FVC and FEV1 in the bilateral transplant group. Among our subjects, double-lung transplantation improved lung function.

    To analyze the evolution of Small Bowel Transplantation program since the beginning of the program. [corrected] All children who underwent intestinal transplantation between 1997 and 2009 were retrospectively reviewed: epidemiological data, status before transplant, surgical technique, immunosupression, results, survival and long.term quality of life were analysed. Fifty-two intestinal transplants were performed in 46 children (20 isolated bowel, 20 combined liver and intestine, and 12 multivisceral); median age was 32m (range 7m-19a); weight 12,3 kg (range 3,9-60); 31 had short gut syndrome, 8 dismotility, 5 intractable diarrhea, and two were miscellaneous. Intestinal adaptation was initially attempted in 26 patients, without success, 20 were directly listed for transplant. The modality of transplant was modified in 17 while listed. Baseline immunosupression consisted of tacrolimus and steroids, although 5 required conversion to Sirolimus later. Six died during the first month, due to sepsis/multiorganic failure (poor status at transplant); 13 died during the long-term follow-up. Acute rejection was seen in 20, chronic rejection in 3, PTLD in 8 (6 died) and GVHD in 5 patients (3 died). Overall survival after 5 years of follow-up is 65,2 % (51,7% for the graft). From 2006 to 2008, overall patient/graft survival at 6 m, 1 and 3 years after transplant is 88,7/84,1, 81,2/81,2 and 81,2/71,1%, respectively. After a median follw-up of 39 +/- 29 months, 27 patients are alive (59%), off TPN, (70% had their ostomy taken down), go to school, are scarcely hospitalized and enjoy a good quality of life. Intestinal transplantation has consolided itself as a good choice for irreversible intestinal failure, being feasible to achieve a normal life. Although overall survival diminishes over time, the center experience has improved the results. These patients need a very close follow-up, once transplant is over, in order to get an early diagnose of immunological complications.

    1993-01-01

    The value of MRI in assessing pancreatic transplants was studied in 37 patients. Sixty-seven MRI examinations were performed in patients with an uncomplicated transplant, 14 in patients with poorly functioning transplant, and 10 in patients with a non-functioning graft. On the basis of 54 follow-up studies, it was shown that the volume of the graft decreased systematically during the 8 months after transplantation. On T1-weighted images the normal transplant was poorly delineated, with an almost homogeneous isointense or slightly hyperintense structure when compared with either renal transplant cortex or muscle. On T2-weighted images the organ was isointense or slightly hypointense compared with fat and hyperintense compared with muscle. T2-weighted delayed echo time image (TR = 2000 ms, TE = 150-200 ms) showed transplanted pancreas as well-delineated, hypointense and with a lobulated structure. This structure was characteristic of normal whole pancreatic grafts. Patent transplant vessels were seen as tubular structures of low signal intensity on T2-weighted short echo time images (TR = 2000 ms, TE = 50 ms). In the 10 patients with a non-functioning pancreatic transplant there were: 4 cases of focal intraparenchymal abnormalities, 6 cases in which the lobular structure was absent, and 4 cases of absence of patent graft main vessels (3 thromboses). There was no configuration of signal intensity of pancreatic parenchyma on MRI which could be considered typical for normal or non-functioning transplant. (orig.)

  8. SURGICAL NUTRITION

    2015-07-01

    Full Text Available A patient undergoing surgery faces great physiologic and psychologic stress. so nutritional demands are greatly increased during this period and deficiencies can easily develop. If these deficiencies are allowed to develop and are not in screening, serious malnutrition and clinical problem can occur. Therefore careful attention must be given to a patient's nutritional status in preparation of surgery, as well as to the individual nutritional needs. If these needs are met, complications are less likely developing. Natural resources provide for rapid recovery. Proper nutrition can speed healing in surgical patients with major trauma, severe malnutition, burns, and other severe illnesses. New techniques for tube feeding, intravenous nutrition for patients with serious weight loss due to gastrointestinal disorders, and use of supplements can hasten wound healing and shorten recovery times.

  9. Cutaneous Squamous Cell Carcinomas in Organ Transplant Recipients

    Full Text Available Non-melanoma skin cancers represent a major cause of morbidity after organ transplantation. Squamous cell carcinomas (SCC are the most common cutaneous malignancies seen in this population, with a 65–100 fold greater incidence in organ transplant recipients compared to the general population. In recent years, human papillomaviruses (HPV of the beta genus have been implicated in the pathogenesis of post-transplant SCCs. The underlying mechanism of carcinogenesis has been attributed to the E6 and E7 proteins of HPV. Specific immunosuppressive medications, such as the calcineurin inhibitors and azathioprine, are associated with a higher incidence of post-transplant SCCs compared to other immunosuppressive agents. Compared to other immunosuppressives, mTOR inhibitors and mycophenolate mofetil have been associated with a decreased risk of developing post-transplant non-melanoma skin cancers. As a result, they may represent ideal immunosuppressive medications in organ transplant recipients. Treatment options for post-transplant SCCs include surgical excision, Mohs micrographic surgery, systemic retinoid therapy, adjunct topical therapy, electrodessication and curettage, and radiation therapy.

    Bacterial infections are the most common infections in solid organ transplant recipients. These infections occur mainly in the first month after transplantation and are hospital-acquired. Nosocomial infections cause significant morbidity and are the most common cause of mortality in this early period of transplantation. These infections are caused by multi-drug resistant (MDR) microorganisms, mainly Gram-negative enterobacteria, non-fermentative Gram-negative bacilli, enterococci, and staphylococci. The patients at risk of developing nosocomial bacterial infections are those previously colonized with MDR bacteria while on the transplant waiting list. Intravascular catheters, the urinary tract, the lungs, and surgical wounds are the most frequent sources of infection. Preventive measures are the same as those applied in non-immunocompromised, hospitalized patients except in patients at high risk for developing fungal infection. These patients need antifungal therapy during their hospitalization, and for preventing some bacterial infections in the early transplant period, patients need vaccinations on the waiting list according to the current recommendations. Although morbidity and mortality related to infectious diseases have decreased during the last few years in haematopoietic stem cell transplant recipients, they are still one of the most important complications in this population. Furthermore, as occurs in the general population, the incidence of nosocomial infections has increased during the different phases of transplantation. It is difficult to establish general preventive measures in these patients, as there are many risk factors conditioning these infections. Firstly, they undergo multiple antibiotic treatments and interventions; secondly, there is a wide variability in the degree of neutropenia and immunosuppression among patients, and finally they combine hospital and home stay during the transplant process. However, some simple measures could be

    Limited data exist regarding the evaluation and selection of older candidates for transplantation. To help guide the development of program protocols and help define research questions in this area, we surveyed U.S. transplant centers regarding their current practices in the evaluation of older kidney transplant candidates. We emailed a 28-question survey to the medical and surgical directors of 190 adult kidney transplant programs in the USA. We received usable responses from 59 programs, a 31.1% response rate. Most (76.3%) programs do not have absolute age cutoffs for listing patients, but for the 22.0% of programs that do have cutoffs, the mean age was 79, range 70-90. Nearly one-third (29.2%) of programs require a minimum life expectancy to list for transplant, reporting a mean of 4.5 years life expectancy, (range 2-10). Programs vary significantly in evaluating candidates living in a nursing home or with cognitive impairments. Practices regarding the evaluation of older transplant candidates vary widely between U.S. programs. Further studies are needed on the impact of age and other comorbidities on transplant outcomes, to help guide decisions on which older patients are most appropriate for transplant listing. © 2017 John Wiley & Sons A/S.

    This article presents an overview of factors associated with thoracic transplantation outcomes over the past decade and provides valuable information regarding the heart, lung, and heart-lung waiting lists and thoracic organ transplant recipients. Waiting list and post-transplant information is used to assess the importance of patient demographics, risk factors, and primary cardiopulmonary disease on outcomes. The time that the typical listed patient has been waiting for a heart, lung, or heart-lung transplant has markedly increased over the past decade, while the number of transplants performed has declined slightly and survival after transplant has plateaued. Waiting list mortality, however, appears to be declining for each organ and for most diseases and high-severity subgroups, perhaps in response to recent changes in organ allocation algorithms. Based on perceived inequity in organ access and in response to a mandate from Health Resources and Services Administration, the lung transplant community is developing a lung allocation system designed to minimize deaths on the waiting list while maximizing the benefit of transplant by incorporating post-transplant survival and quality of life into the algorithm. Areas where improved data collection could inform evolving organ allocation and candidate selection policies are emphasized.

    Full Text Available PURPOSE: To evaluate meniscal transplantation using as fixation method a synthetic glue derived from cyanoacrylate acid. METHODS: Twenty rabbits were used, of which 10 for autologous transplantation and 10 for homologous transplantation. For the autologous transplantation the meniscus was removed, and then transplanted in the same animal, using the synthetic glue. For the homologous transplantation, the study was divided into two stages: 1- Removal of the meniscus which was maintained at a temperature of 73ºC. 2- Use of cyanoacrylate acid-derived surgical adhesive for meniscal retransplantation in a different rabbit 30 days after the transplant. RESULTS: Due to complications, euthanasia had to be anticipated to the 15th day in the homologous group and to the 18th day in the autologous group. Macroscopically, knees submitted to transplantation presented whitish secretions from the surgical incision up to deep planes. Necrosis was observed in both groups. Statistical analysis has shown that mild (p=0.043 and moderate (p=0.001 complications emerged in a significantly earlier way in the homologous group, where euthanasia was also performed earlier (p=0,005. CONCLUSION: Synthetic surgical adhesives derived from cyanoacrylate acid promoted cortical to medullary bone necrosis bone in both groups.OBJETIVO: Avaliar macroscópica e histologicamente o transplante meniscal, utilizando-se a cola sintética derivada do ácido cianoacrilato como método de fixação.

    There have been biliary complications since the beginning of liver transplants, and is a topic of great interest due to its high incidence, as well as their influence on morbidity and mortality. The biliary fistula is currently uncommon and its management is straightforward. Anastomotic stenosis continues to have an incidence of 10-15%. Although the current treatment of choice is endoscopic retrograde cholangiopancreatography (ERCP), surgical treatment (hepatico-jejunostomy) continues to have an important role. Non-anastomotic stenosis has an incidence of 5-10%, and is associated with ischaemic or immunological factors, and usually involves a re-transplant. Choledocholithiasis has an incidence of 5-10%, with the treatment of choice being ERCP. However the treatment of biliary complications should be individualised. We must take into account, liver function, the general health status of the patient, and the availability and experience of the team in the different therapeutic options. Copyright © 2011 AEC.

  20. A review of the imaging and intervention of liver transplant complications.

    LENUS (Irish Health Repository)

    McEvoy, S

    2010-09-01

    Liver transplantation has become a successful surgical solution to a variety of medical and oncological parenchymal liver diseases. As a result, these patients are being encountered more frequently within diagnostic imaging departments which may be remote from the transplant centre. Radiologists must therefore be proficient in identifying normal post-transplant anatomy which involves the anastomosis of four structures between the donor and recipient, namely the hepatic artery, the main portal vein, the retro-hepatic inferior vena cava and the extra-hepatic bile ducts. A number of potential complications can arise involving any or all of these structures, which can be potentially devastating and lead to graft failure. Radiologists must familiarise themselves with the normal post-operative appearances of liver transplantation and become competent in diagnosing post-transplant complications. Where possible, complications should be treated using interventional radiological techniques, thus avoiding the need for repeat surgical intervention or retransplantation.

    The aim of this study was to assess the pulp survival that occur in transplants of autologous teeth, by comparing two surgical techniques: the conventional technique (autotransplantation for newly formed alveoli), and an alternative technique, (autotransplants for alveoli in the initial phase of healing). In each surgical techniques were applied, randomly, either saline solution or Emdogain®. The study group comprised 26 patents, in which 28 teeth were transplanted to recipient sockets prepared mechanically. Of the 28 teeth transplanted, 4 were intentional replants, and of the remainer, 11 had the apex closed and 13 open. The mean age at the time of transplantation was 22.34 ± 8.14 years (mean ± SD). The transplantation were performed by the same operator, with the informed consent of the patient and authorized by the ethical committee of the hospital. Clinical and radiological examinations were performed during 24 to 65 months (48 ± 12.96; MED ± SD), from 10 days, 1 month, 3 months, 6 months and annually to 5.6 years. Only two transplanted teeth were lost, due persistent apical periodontitis, and one transplanted patient with open apex missed the treatment. In the teeth with pulp, we needed to perform root canal therapy in 9. In the 73% of the teeth with closed apex, we needed to perform root canal treatment, with no statistically significant difference found among closed apex and root canal therapy (p=0.083). In only 8% of the teeth with open apex did we need to perform root canal treatment, with an association between open apex and root canal therapy (p=0.0002). The overall success rate was 98% with significant difference for losses (p=0.0001). Although not a frequent procedure, it was concluded that autotransplanted teeth, performed with appropriate surgical care had a good prognosis, and can render a very useful service to the patients.

    Patients after liver transplant have a high incidence of chronic kidney disease and end-stage renal disease (ESRD). We investigated kidney transplantation after liver transplantation using the Organ Procurement Transplant Network database. The Organ Procurement Transplant Network database was queried for patients who received kidney transplantation after previous liver transplantation. These patients were compared with patients who received primary kidney transplantation alone during the same time period. Between 1997 and 2008, 157,086 primary kidney transplants were performed. Of these, 680 deceased donor kidney transplants and 410 living donor kidney transplants were performed in previous recipients of liver transplants. The number of kidney after liver transplants performed each year has increased from 37 per year to 124 per year in 2008. The time from liver transplant to kidney transplant increased from 8.2 to 9.0 years for living donor transplants and from 5.4 to 9.6 years for deceased donor. The 1, 3, and 5 year actuarial graft survival in both living donor kidney after liver transplant and deceased donor kidney after liver transplant are less than the kidney transplant alone patients. However, the death-censored graft survivals are equal. The patient survival is also less but is similar to what would be expected in liver transplant recipients who did not have ESRD. In 2008, kidney after liver transplantation represented 0.9% of the total kidney alone transplants performed in the United States. Kidney transplantation is an appropriate therapy for selected patients who develop ESRD after liver transplantation.

    Since the initial successful kidney transplantations in humans, the field of renal transplantation has made significant progress. Patient survival and graft survival have improved tremendously. Our armamentarium of immunosuppressive drugs and antimicrobial agents has expanded, as our understanding of their effects and proper utilization. Enhanced surgical techniques also improved the overall survival of kidney recipients. However, infectious complications remain a major cause of morbidity and mortality in this patient population. In this article, we provide an overview of infections in kidney transplant recipients, a detailed illustration of specific infectious agents with a focus on cytomegalovirus, and finally we lay some general principles for limiting the burden of infectious complications in kidney transplants through proper infection control measures.

    Hand allotransplantation can restore motor, sensory and cosmetic functions to upper extremity amputees. Over 70 hand transplant operations have been performed worldwide, but there is little published regarding post-hand transplant rehabilitation. The Brigham and Women's Hospital (BWH) Hand Transplantation Team's post-hand transplant rehabilitation protocol is presented here. The protocol must be modified to address each transplant recipient's unique needs. It builds on universally used modalities of hand rehabilitation such as splinting, edema and scar management, range of motion exercises, activities of daily living training, electrical stimulation, cognitive training and strengthening. The BWH hand transplant rehabilitation protocol consists of four phases with distinct goals, frequency, and modalities. (1) Pre-operative: functional assessments are completed and goals and expectations of transplantation are established. (2) Initial post-operative (post-operative weeks 1-2): hand protection, minimization of swelling, education, and discharge. (3) Intermediate (post-operative weeks 2-8): therapy aims to prevent and/or decrease scar adhesion, increase tensile strength, flexibility and function, and prevent joint contractures. (4) Late (from 8 weeks forward): maximization of function and strength, and transition to routine activities. The frequency of rehabilitation therapy decreases gradually from the initial to late phases. Rehabilitation therapy after hand transplantation follows a progressive increase in activity in parallel with wound healing and nerve regeneration. Careful documentation of progress and outcomes is essential to demonstrate the utility of interventions and to optimize therapy protocols.

    Even if reproductive medicine has been remarkably successful during the past few decades, with the introduction of in vitro fertilization in the late 1970s and intracytoplasmic sperm injection in the early 1990s, it has been repeatedly mocked by infertility due to an absolute uterine factor. No treatment has been available for the women suffering from an absent or dysfunctional uterus, in terms of carrying a pregnancy. Approximately one in 500 women suffer from absolute uterine infertility, and the option so far to become a mother has been to either adopt or utilize gestational surrogacy. As of today, a total of eleven cases of human uterus transplantations have been reported worldwide, conducted in three different countries. The results of these initial experimental cases far exceed what might be expected of a novel surgical method. Many more uterus transplantations are to be expected in the near future, as other research teams’ preparations are being ready to be put into clinical practice. In this review, we summarize the current worldwide experience of uterus transplantation as a treatment of absolute uterine factor infertility and the future prospects of human uterus transplantation.

    Articular cartilage in adults has a limited capacity for self-repair after a substantial injury. Surgical therapeutic efforts to treat cartilage defects have focused on delivering new cells capable of chondrogenesis into the lesions. Autologous chondrocyte transplantation (ACT) is an advanced cell-based orthobiologic technology used for the treatment of chondral defects of the knee that has been in clinical use since 1987 and has been performed on 12,000 patients internationally. With ACT, good to excellent clinical results are seen in isolated post-traumatic lesions of the knee joint in the younger patient, with the formation of hyaline or hyaline-like repair tissue. In the classic ACT technique, chondrocytes are isolated from small slices of cartilage harvested arthroscopically from a minor weight-bearing area of the injured knee. The extracellular matrix is removed by enzymatic digestion, and the cells are then expanded in monolayer culture. Once a sufficient number of cells has been obtained, the chondrocytes are implanted into the cartilage defect, using a periosteal patch over the defect as a method of cell containment. The major complications are periosteal hypertrophy, delamination of the transplant, arthrofibrosis and transplant failure. Further improvements in tissue engineering have contributed to the next generation of ACT techniques, where cells are combined with resorbable biomaterials, as in matrix-associated autologous chondrocyte transplantation (MACT). These biomaterials secure the cells in the defect area and enhance their proliferation and differentiation.

    The objective of this review is to give a state of affairs of meniscal transplantation, with the accent on preservation and surgical techniques. All articles were selected by performing a search on the literature by using relevant keywords. The most relevant articles were selected with close attention to the publication date. When a meniscal tear is diagnosed, suture can be an option in the vascular zone, whereas the more frequently affected avascular zone heals poorly. A meniscectomy however is not without consequences, wherefore meniscal transplantation can be seen as a therapeutic option for pain reduction and improvement of function when the meniscus is lost. The meniscal scaffold, allograft and autograft can be currently withheld as possible grafts, where the meniscal scaffolds hold great promise as an alternative to the allograft. Various fixation techniques are therefore developed, where viable, deep frozen as well as cryopreservated allografts seem to give the most promising short term results. The transplantation can be performed using an open as well as an arthroscopic technique, using soft tissue fixation, bone plugs or blocks. De primacy of one technique can't be proven. In general meniscal transplantation can be considered as an acceptable procedure. Since the outcomes of different studies are difficult to compare, an attempt should be made to limit new studies to the comparison of one aspect. We can conclude that larger, more comparative randomised controlled long-term studies are necessary to resolve which techniques can give the best long-term results.

    2011-01-01

    Organ transplants are currently an alternative treatment for a growing number of diseases, which were previously considered terminal. Bioethics has played an important role since the advent of this surgical technique, mainly in defining death criteria and the optimum transplantation conditions. This issue continues being a universal focal point, mainly concerning the equity of access to transplantation, criteria for assigning deceased-donor organs, living-donor safety, risk of commercial trade, fair access to high-quality immunosuppressive drugs and organ transplant legislation. These problems are characteristic of Latin America and the Caribbean, and were the driving force behind the First Latin American Bioethics and Transplant Forum, sponsored by the Latin American and Caribbean Transplant Society (STALYC), and all the transplant societies from subsidiary countries. The "Document of Aguascalientes" is a collection of all the ideas and opinions that were proposed during round tables and analyses. The document is divided into four sections: 1) living donor; 2) organ trading and transplant tourism; 3) the state role in legislation, transplant distribution and coverage; and 4) access to and quality of immunosuppression. The Bioethics and Transplant Forum was created to analyse and find solutions for this complex issue. The "Document of Aguascalientes" aims to serve as an instrument of expression and a vehicle for the ideas put forward during the Forum, so that they can act as transplant practice guidelines in Latin America.

    Full Text Available In the past decade, policymakers and commentators across the world have called for the introduction of copyright reform based on the fair use model in the United States. Thus far, Israel, Liberia, Malaysia, the Philippines, Singapore, South Korea, Sri Lanka and Taiwan have adopted the fair use regime or its close variants. Other jurisdictions such as Australia, Hong Kong and Ireland have also advanced proposals to facilitate such adoption. This article examines the increasing efforts to transplant fair use into the copyright system based on the U.S. model. It begins by briefly recapturing the strengths and weaknesses of legal transplants. The article then scrutinizes the ongoing effort to transplant fair use from the United States. Specifically, it identifies eight modalities of transplantation. This article concludes with five lessons that can be drawn from studying the ongoing transplant efforts.

    Full Text Available Madeleine Oliver,1 Christopher Chiodo Ortiz,2 Jorge Ortiz31University of Toledo College of Medicine, Toledo, OH, 2Bucknell University, Lewisburg, PA, 3Department of Transplant Surgery, University of Toledo Medical Center, Toledo, OH, USA Abstract: Caring for liver transplant patients suffering from chronic hepatitis C virus (HCV infection is a challenging task for transplant surgeons and primary physicians alike. HCV is the leading cause of liver transplantation in the USA and comes with a myriad of complications that increase morbidity and mortality. This review focuses on patient follow-up, spanning from before the liver transplant occurs to the patient's long-term health. Pretransplant, both donor and recipient variables, must be carefully chosen to ensure optimal surgical success. Risk factors must be identified and HCV viral load must be reduced to a minimum. In addition to standard transplant complications, HCV patients suffer from additional problems, such as fibrosing cholestatic hepatitis and widespread viremia. Physicians must focus on the balance of immunosuppressive and antiviral medications, while considering possible side effects from these potent drugs. Over the years following surgery, physicians must identify any signs of failing liver health, as HCV-positive patients have an increased risk for cirrhosis and certain life-threatening malignancies.

    As the ability to transplant organs and tissues has grown, the demand for these procedures has increased as well—to the point at which it far exceeds the available supply creating the core ethical challenge for transplantation—rationing. The gap between supply and demand, although large, is worse than it appears to be. There are two key steps to gaining access to a transplant. First, one must gain access to a transplant center. Then, those waiting need to be selected for a transplant. Many potential recipients do not get admitted to a program. They are deemed too old, not of the right nationality, not appropriate for transplant as a result of severe mental impairment, criminal history, drug abuse, or simply because they do not have access to a competent primary care physician who can refer them to a transplant program. There are also financial obstacles to access to transplant waiting lists in the United States and other nations. In many poor nations, those needing transplants simply die because there is no capacity or a very limited capacity to perform transplants. Although the demand for organs now exceeds the supply, resulting in rationing, the size of waiting lists would quickly expand were there to suddenly be an equally large expansion in the number of organs available for transplantation. Still, even with the reality of unavoidable rationing, saving more lives by increasing organ supply is a moral good. Current public policies for obtaining organs from cadavers are not adequate in that they do not produce the number of organs that public polls of persons in the United States indicate people are willing to donate.

    Full Text Available To determine the prevalence of urological and vascular complications in renal trans-plant recipients (RTx at Tabriz Renal Transplant Center, we studied 55 recipients of renal allo-grafts (25 male and 29 female patients with a mean age of 38.3 ± 13.4 years from October 2005 to November 2006. The surgical complications in our study included hematomas: 20.4%, renal artery stenosis: 20.4%, calculi: 7.4%, hydronephrosis or ureteral stricture: 5.6%, urinary leakage: 5.6%, lymphoceles: 1.9%, and renal vein thrombosis: 1.9%. We conclude that the most common urologic complications in our center were ureteric strictures and urine leaks, and the most common vascular complication was renal artery stenosis.

  15. Biliary atresia. A surgical perspective.

    The combination of portoenterostomy with subsequent liver transplantation is the treatment of choice for patients with biliary atresia. It is important, however, to attempt to keep the patient's own organ by continuing efforts to achieve the best possible results with portoenterostomy. Additional basic research, perhaps concerning on the role of cytokines and apoptosis in the control of biliary atresia, may provide insight into possible new medical strategies for treating patients with biliary atresia. For example, in addition to portoenterostomy, control of apoptosis at various cellular levels and of bile duct cell proliferation and maturation by manipulation of the growth factors and cytokines may become part of future treatment modalities. Another direction of research should be the control of fibrogenesis, which might be accomplished by blocking TGF-beta 1 and platelet-derived growth factor and by HGF gene therapy. The author's current strategy for surgical treatment for patients with biliary atresia include (1) early diagnosis, including prenatal diagnosis and broader use of mass screening programs, (2) hepatic portoenterostomy, without stoma formation; (3) close postoperative care, especially for prevention of postoperative cholangitis; (4) revision of portoenterostomy only in selected cases; (5) early liver transplantation in patients with absolutely failed portoenterostomy; (6) avoidance of laparotomy for the treatment of esophageal varices and hypersplenism; (7) consideration of exploratory laparotomy or primary liver transplantation for patients with advanced liver disease at the time of referral. The development of new treatment modalities based on the understanding of the pathogenesis of the disease, and especially on the biology of intrahepatic bile ducts and hepatic fibrosis, is essential.

    Aplastic anemia is usually treated with immunosuppression or allogeneic transplant, depending on patient and disease characteristics. Syngeneic transplant offers a rare treatment opportunity with minimal transplant-related mortality, and offers an insight into disease mechanisms. We present here...... a retrospective analysis of all syngeneic transplants for aplastic anemia reported to the European Group for Blood and Marrow Transplantation. Between 1976 and 2009, 88 patients received 113 transplants. Most transplants (n=85) were preceded by a conditioning regimen, 22 of these including anti-thymocyte globulin...

    The transplantation of organs and tissues from one human to another human has become an essential and well established form of therapy for many types of organ and tissue failure. In Malaysia, kidney, cornea and bone marrow transplantation are well established. Recently, liver, bone and heart transplanation have been performed. Unfortunately, because of the lack of cadaveric organ donation, only a limited number of solid organ transplantation have been performed. The cadaveric organ donor rate in Malaysia is low at less than one per million population. The first tissue transplanted in Malaysia was the cornea which was performed in the early 1970s. At that time and even now the majority of corneas came from Sri Lanka. The first kidney transplant was performed in 1975 from a live related donor. The majority of the 629 kidney transplants done at Hospital Kuala Lumpur to date have been from live related donors. Only 35 were from cadaver donors. Similarly, the liver transplantation programme which started in 1995 are from live related donors. A more concerted effort has been made recently to increase the awareness of the public and the health professionals on organ and tissue donation. This national effort to promote organ and tissue donation seems to have gathered momentum in 1997 with the first heart transplant successfully performed at the National Heart Institute. The rate of cadaveric donors has also increased from a previous average of I to 2 per year to 6 per year in the last one year. These developments are most encouraging and may signal the coming of age of our transplantati on programme. The Ministry of Health in conjunction with various institutions, organizations and professional groups, have taken a number of proactive measures to facilitate the development of the cadaveric organ donation programme. Efforts to increase public awareness and to overcome the negative cultural attitude towards organ donation have been intensified. Equally important are efforts

    Since the number of women with renal cadaver transplantation is increasing, the obstetrician seems himself more often confronted with the situation: pregnancy after renal transplantation. The purpose of this paper is to report about our own case, to give a review of international studies written on this subject, and to inform the obstetrician, the surgeon and the pediatrician about the following points: - Common aspects of renal transplantation in fertile women and the information to be given to the patient. - Selection criteria and anticonception. - Pregnancy assessment and delivery - Pediatric problems.

  20. Pancreatic islet transplantation

    Full Text Available Abstract Background No formulation of exogenous insulin available to date has yet been able to mimic the physiological nictemeral rhythms of this hormone, and despite all engineering advancements, the theoretical proposal of developing a mechanical replacement for pancreatic β cell still has not been reached. Thus, the replacement of β cells through pancreas and pancreatic islet transplantation are the only concrete alternatives for re-establishing the endogenous insulin secretion in type 1 diabetic patients. Since only 1 to 1.5% of the pancreatic mass corresponds to endocrine tissue, pancreatic islets transplantation arises as a natural alternative. Data from the International Islet Transplant Registry (ITR from 1983 to December 2000 document a total of 493 transplants performed around the world, with progressively worse rates of post-transplant insulin independence. In 2000, the "Edmonton Protocol" introduced several modifications to the transplantation procedure, such as the use of a steroid-free immunosuppression regimen and transplantation of a mean islet mass of 11,000 islet equivalents per kilogram, which significantly improved 1-year outcomes. Although the results of a 5-year follow-up in 65 patients demonstrated improvement in glycemic instability in a significant portion of them, only 7.5% of the patients have reached insulin independence, indicating the need of further advances in the preservation of the function of transplanted islet. In addition to the scarcity of organs available for transplantation, islets transplantation still faces major challenges, specially those related to cell loss during the process of islet isolation and the losses related to the graft site, apoptosis, allorejection, autoimmunity, and immunosuppression. The main strategies to optimize islet transplantation aim at improving all these aspects. Conclusion Human islet transplantation should be regarded as an intervention that can decrease the frequency of

    Surgical wound infections are more frequent in patients undergoing heart transplantation than in other heart surgery patients. There is a wide spread of sternal wound infection incidence in transplant patients ranging from 4% to 40%. It is first study describing local gentamicin sponge application during heart transplantation procedure. We enrolled 75 patients in a retrospective, single-center study, including 25 patients who underwent orthotopic heart transplantation (heart transplant group) and 50 in the cardiac surgery group. They were in mean age of 49 ± 12 years and 51 ± 13 years in heart transplantation and cardiac surgery group, respectively. A gentamicin sponge was inserted intraoperatively between sternal borders before chest closure in all heart transplantation patients. There was 1 early death (4%) on postoperative day 7 owing to Clostridium difficile infection in the heart transplant group. There was 1 death (2%) in the cardiac surgery group owing to multiorgan failure secondary to perioperative heart ischemia. There was neither bacterial sternal wound infection nor sternal instability in the heart transplant group. None of the patients who had gentamicin sponge applied had wound healing problems. Two patients (4%) had a deep sternal wound infection in the cardiac surgery group, who had no sponge application; 1 (2%) was treated by surgical debridement and active drainage and 1 (2%) by vacuum therapy. There were 11 patients (44%) discharged on insulin therapy in the heart transplant group and 21 (21%) in the cardiac surgery group. Mean overall postoperative hospital stay was 35 ± 19 days in the heart transplant group and 10 ± 4 days in the cardiac surgery group. Gentamicin sponge is an effective local infection prophylaxis in heart transplant patients. Copyright © 2015 Elsevier Inc. All rights reserved.

    2017-08-02

    Objective: To analyze the risk factors of nosocomial infection after liver transplantation in children, so as to provide scientific evidence for the prevention and control of nosocomial infection. Method: Clinical data of 223 pediatric patients undergoing liver transplantation between January 2014 and December 2015 were analyzed retrospectively. Univariate and multivariate analyses were carried out to investigate the risk factors of infection after transplantation. Result: Totally 51 children were infected among the 223 patients, the infection rate was 22.86%(51/223). Among the 74 cases with infection, 38 were infected with the blood (included peripherally inserted central catheters) accounting for 51.35 %; and surgical site infection accounted for 21.62%, the respiratory tract infections accounted for 18.92% and the other infections accounted for 8.11%. Totally 74 strains of infectious pathogens were found in 51 cases of infected patients, including Gram-negative bacteria accounting for 48.65%, Gram-positive bacteria accounting for 44.59% and the fungus accounting for 6.76%. According to a variety of survey factors, univariate analysis showed factors of hospitalization time, hospitalization time before surgery, surgical duration, and reoperation had statistically significant association with nosocomial infection( P nosocomial infection after pediatric liver transplantation. Conclusion: There are a variety of risk factors for the postoperative infections after liver transplantation in children. It is necessary to take into account the surgery factor, medical staff factor and hospital management factor. Management strengthening of these factors is necessary to reduce the infection rate.

  3. Face Transplantation: On the Verge of Becoming Clinical Routine?

    2014-01-01

    Full Text Available Introduction. Face transplantation (FT is an innovative achievement of modern reconstructive surgery and is on the verge of becoming a common surgical opportunity. This review article was compiled to provide an update on this surgical field, especially regarding clinical outcomes, benefits, and complications implied. Methods. We performed an extensive research on all English-language Medline articles, case reports, and reviews published online until September 15, 2013. Used search terms were “face transplantation,” “face transplant,” “facial transplantation,” “facial transplant,” “face allograft,” and “facial allograft.” Results. To date 27 FTs have been performed worldwide. 19 of these cases have been published in the Medline database. Long-term follow-up reports of FT cases are rare. Three deaths associated with the procedure have occurred to date. The clinical outcomes of FT are satisfying. Reinnervation of sensation has been faster than motor recovery. Extensive functional improvements have been observed. Due to strict immunosuppression protocols, no case of hyperacute or chronic rejection and no graft-versus-host disease have occurred to date. Conclusions. As studies on long-term outcomes are missing, particularly regarding immunosuppression-related complications, FT will stay experimental for the next years. Nevertheless, for a small group of patients, FT already is a feasible reconstructive option.

  4. Urolithiasis in renal transplantation: Diagnosis and management

    2014-12-01

    Full Text Available Obiectives: To report our experience of diagnosis and multimodal management of urolithiasis in renal transplantation. Patients and Methods: From January 1995 to December 2012, 953 patients underwent renal transplantation in the Kidney Transplant Unit of Treviso General Hospital. Ten (10% of them developed urinary calculi and were referred at our institution. Their mode of presentation, investigation and treatment were recorded. Results: Seven had renal and 3 ureteral calculi. Urolithiasis was incidentally discovered on routine ultrasound in 6 patients, 1 presented with oliguria, 1 with anuria and acute renal failure and in 2 urolithiasis was found at removal of the ureteral stent. Nephrostomy tube was placed in 5 patients. Hypercalcemia with hyperparathyroidism (HPT was present in 5 patients and hyperuricemia in 3. Two patients were primary treated by shock wave lithotripsy (SWL and one of them was stone-free after two sessions. Two patients, one with multiple pielocaliceal calculi and the other with staghorn calculus in the lower calyx, were treated with percutaneous nephrolitothotomy (PCNL. Three patients were treated by ureteroscopy (URS and in one of them two treatments were carried out. One patient had calculus impacted in the uretero-vesical anastomosis and surgical ureterolithotomy with re-do ureterocystoneostomy was performed after failure of URS. Two patients with calculi discovered at removal of the ureteral stent were treated by URS. Conclusions: The incidence of urolithiasis in renal transplantation is uncommon. In the most of patients the condition occurs without pain. Metabolic anomalies and medical treatment after renal transplantation may cause stone formation. Advancements in endourology and interventional radiology have influenced the management of urolithiasis that can be actually treated with a minimal incidence of risk for the renal allograft.

    There is an increasing demand for outcomes analysis, including quality of life and financial analysis, following medical interventions and surgical procedures. We analyzed outcomes for 100 consecutive patients undergoing liver transplantation during a period of case management revision. Patient survival was calculated by Kaplan-Meier actuarial methods. The Karnofsky performance status was objectively assessed for surviving patients up to 6 years after transplantation and was evaluated by repeated measures analysis of variance and covariance. Subjective evaluation of quality of life over time was obtained using the Psychosocial Adjustment to Illness Scale. The correlations between time and scale were calculated. Financial data were accumulated from billing records. Six-month, 1-year, 2-year, and 3- through 5-year survival was 86%, 84%, 83%, and 78%, respectively. Karnofsky performance status confirmed poor functional status preoperatively with a mean of 53 +/- 2, but significantly improving to 72 +/- 2 at 3 months, 80 +/- 2 at 6 months, 90 +/- 1 at 1 year, 92 +/- 1 at 2 years, 94 +/- 1 at 3 years, 96 +/- 1 at 4 years, and 97 +/- 1 at 5 years (P <0.001). Psychosocial Adjustment to Illness Scale scores demonstrated significant improvement following transplantation overall (r = -0.33), improving most in sexual relationships (r = -0.41), and domestic environment (r = -0.35; P <0.001). Median length of stay for the first half of the patients was 19 days declining to 11 days for the second half. Median hospital charges declined from $105,000 to $90,000. Quality of life parameters assessed both by care givers (Karnofsky) and by patients (Psychosocial Adjustment to Illness Scale) improved dramatically following transplantation and over time, demonstrating that liver transplantation effectively restores a good quality of life. Outcomes can be improved while reducing length of stay and charges through modifications in case management.

    Non-surgical endodontic retreatment is the treatment of choice for endodontically treated teeth with recurrent or residual disease in the majority of cases. In some cases, surgical endodontic treatment is indicated. Successful micro-surgical endodontic treatment depends on the accuracy of diagnosis, appropriate case selection, the quality of the surgical skills, and the application of the most appropriate haemostatic agents and biomaterials. This article describes the armamentarium and technical procedures involved in performing micro-surgical endodontics to a high standard.

    Although renal transplantation was a therapeutic reality in Norway from 1969, organ transplantation was largely regarded as experimental surgery from its introduction in the early 1950s until the licensing of ciclosporin in 1982. After the first successful renal transplantation in 1954, 13 years elapsed before a liver and a heart were successfully transplanted, both in 1967. Inspired by the pioneers Thomas Starzl in Denver, Colorado, and Roy Yorke Calne in Cambridge, early in 1968 Snorre Aune, Gunnar Schistad and Andreas Skulberg began experimental studies on pigs at Ullevål Hospital to develop a surgical technique for liver transplantation. They collaborated with a team at Rikshospitalet led by Audun Flatmark and performed transplantations there every other week, and every other week at Ullevål. It took over one year of weekly animal experiments before the first transplanted pig survived. The first three transplantations on humans in Norway were performed at Ward 2, Ullevål Hospital in 1969, 1970 and 1972. The first patient died shortly after surgery, the second after 24 days, the third 54 days after transplantation. Snorre Aune, Gunnar Schistad and Andreas Skulberg were awarded the Michael Skielderup gold medal in 1972 for this pioneering work. The article is based on the author's own experience as an assistant surgeon and junior partner in the animal experiments and the first human liver transplantations in Norway, and a survey of relevant publications.

    Full Text Available Kidney transplantation in patients with end stage renal diseaseis preferred to dialysis because transplantation provides a betterquality of life and improved survival. However, the gapbetween the supply and demand for a renal allograft is wideningand the waiting time is increasing. Iranian protocol, a controlledtransplant program supported by the government forliving unrelated donors, was initiated for solving the problemof organ shortage. Although this system might experiencechallenges, clearly it has advantages over other organ procurementsystems primarily that thousands in need do not diewhile waiting for a compatible donor.In the present review I discuss the history of renal transplantationin Iran, "Iranian model" protocol, the situation ofIran’s kidney transplantation from either living or deceaseddonors compared with the Middle East countries, and our experiencesof unrelated renal transplantation.

    Today, most causes of infertility are successfully treated. Yet there is still a subgroup of female infertility affecting around 4%, which so far is untreatable because of an absolute uterine factor. To acquire motherhood, these women are today referred to either adoption or surrogacy. Research in the field of uterus transplantation has been evaluated in different animal models for decades and has presently reached a human clinical application as a possible treatment for absolute uterine factor infertility. Organ transplantation is no longer reserved to those with a life-threatening disease and neither is organ transplantation together with concurrent immunosuppression prohibiting pregnancy. Uterus transplantation involves four parties - recipient, donor, partner of recipient and future child - and is a subject of ethical controversies. Copyright © 2014 Elsevier Ltd.

    Lung transplantation (LT) is a therapeutic option with controversial results in chronic obstructive pulmonary disease (COPD). We aimed to analyze the outcomes of transplantation in terms of lung function and to identify prognostic factors. A retrospective analysis of 107 patients with COPD receiving lung transplants in the La Fe Hospital between 1991 and 2008 was performed. Preoperative variables, pulmonary function tests before and after LT, surgical procedure variables and long-term monitoring, expressed as mean or percentage, as applicable, were analyzed. Spirometric results before and after LT were analyzed. Linear or logistic regression were used for multivariate analysis depending on the variable. Ninety-four men (87.9%) and 13 women (12.1%) were transplanted, with a mean age±standard deviation of 52.58±8.05 years; 71% of LTs were double-lung transplantations. Spirometric values improved after LT: FVC: +1.22L (+34.9%), FEV1: +1.66L (+56.7%) and FEF25-75: +1.85L (+50.8%); P=.001. This functional improvement was maintained after 5 years only in the group with BODE score >7 (P=.001). Recipient height, type of LT, use of extracorporeal circulation during the surgical procedure, presence of bronchiolitis obliterans syndrome and the age and cause of death of the donor significantly influenced lung function over time. LT improves lung function in COPD patients. This improvement was maintained at 5years only in patients with BODE>7. Double lung transplantation provides better functional results than single-lung transplantation. Copyright © 2014 SEPAR. Published by Elsevier Espana. All rights reserved.

    Uterus transplantation is the first available treatment for absolute uterine infertility, which is caused by absence of the uterus or the presence of a non-functional uterus. Eleven human uterus transplantation attempts have been done worldwide but no livebirth has yet been reported. In 2013, a 35-year-old woman with congenital absence of the uterus (Rokitansky syndrome) underwent transplantation of the uterus in Sahlgrenska University Hospital, Gothenburg, Sweden. The uterus was donated from a living, 61-year-old, two-parous woman. In-vitro fertilisation treatment of the recipient and her partner had been done before transplantation, from which 11 embryos were cryopreserved. The recipient and the donor had essentially uneventful postoperative recoveries. The recipient's first menstruation occurred 43 days after transplantation and she continued to menstruate at regular intervals of between 26 and 36 days (median 32 days). 1 year after transplantation, the recipient underwent her first single embryo transfer, which resulted in pregnancy. She was then given triple immunosuppression (tacrolimus, azathioprine, and corticosteroids), which was continued throughout pregnancy. She had three episodes of mild rejection, one of which occurred during pregnancy. These episodes were all reversed by corticosteroid treatment. Fetal growth parameters and blood flows of the uterine arteries and umbilical cord were normal throughout pregnancy. The patient was admitted with pre-eclampsia at 31 full weeks and 5 days, and 16 h later a caesarean section was done because of abnormal cardiotocography. A male baby with a normal birthweight for gestational age (1775 g) and with APGAR scores 9, 9, 10 was born. We describe the first livebirth after uterus transplantation. This report is a proof-of-concept for uterus transplantation as a treatment for uterine factor infertility. Furthermore, the results show the feasibility of live uterus donation, even from a postmenopausal donor. Jane and

    Scheffert, Jenna L; Raza, Kashif

    2014-08-01

    Lung transplantation can be a life-saving procedure for those with end-stage lung diseases. Unfortunately, long term graft and patient survival are limited by both acute and chronic allograft rejection, with a median survival of just over 6 years. Immunosuppressive regimens are employed to reduce the rate of rejection, and while protocols vary from center to center, conventional maintenance therapy consists of triple drug therapy with a calcineurin inhibitor (cyclosporine or tacrolimus), antiproliferative agents [azathioprine (AZA), mycophenolate, sirolimus (srl), everolimus (evl)], and corticosteroids (CS). Roughly 50% of lung transplant centers also utilize induction therapy, with polyclonal antibody preparations [equine or rabbit anti-thymocyte globulin (ATG)], interleukin 2 receptor antagonists (IL2RAs) (daclizumab or basiliximab), or alemtuzumab. This review summarizes these agents and the data surrounding their use in lung transplantation, as well as additional common and novel therapies in lung transplantation. Despite the progression of the management of lung transplant recipients, they continue to be at high risk of treatment-related complications, and poor graft and patient survival. Randomized clinical trials are needed to allow for the development of better agents, regimens and techniques to address above mentioned issues and reduce morbidity and mortality among lung transplant recipients.

Before transplantation, patients receive intensive myeloablative chemoradiotherapy followed by stem cell “rescue.” Autologous HSCT is performed using the patient’s own hematopoietic stem cells, which are harvested before transplantation and reinfused after myeloablation. Allogeneic HSCT uses human leukocyte antigen (HLA-matched stem cells derived from a donor. Survival after allogeneic transplantation depends on donor–recipient matching, the graft-versus-host response, and the development of a graft versus leukemia effect. This article reviews the biology of stem cells, clinical efficacy of HSCT, transplantation procedures, and potential complications.Keywords: hematopoietic stem cell transplantation, complications

    Full Text Available An ′Indian transplant registry′ has been established over the past two years due to the efforts of the Indian Society of Organ Transplantation. This society is about 20 years old with over 450 members who are doctors and basic scientist. The registry is currently in the first phase of its development and can be partly viewed at www.transplantindia.com. The endeavor has been undertaken with the objective of having a centralized repository of information of the various transplants that are being undertaken in India. In its first phase of the registry ′Fast Fact′ retrospective short datasets are being captured that include the essential details of the transplant programme. The fast fact data includes the number of transplant done yearly, the sex ratio and type of transplant. So far thirteen major institutional data has been entered in the registry. In the second phase of the registry, over twenty fields are likely to be captured and all member institutions would be encouraged to enter the data prospectively. In the third phase data would be derived with ongoing audit features.. The society and its members have supported the formation of the registry and are enthusiastic about its potential.

  6. Hand Transplantation Versus Hand Prosthetics: Pros and Cons.

    Science.gov (United States)

    Salminger, S; Roche, A D; Sturma, A; Mayer, J A; Aszmann, O C

    Composite tissue transplantation and new developments in the field of prosthetics have opened new frontiers in the restoration of function among upper limb amputees. It is now possible to restore hand function in affected patients; however, the indications, advantages, and limitations for either hand transplantation or prosthetic fitting must be carefully considered depending on the level and extent of the limb loss. Hand transplantation allows comprehensive hand function to be restored, yet composite tissue transplantation comes with disadvantages, making this method a controversial topic in the hand surgical community. Alternatively, prosthetic limb replacement represents the standard of care for upper limb amputees, but results in the known limitations of function, sensation, and usage. The indication for hand transplantation or prosthetic fitting strongly depends on the level of amputation, as well as on the extent (unilateral/bilateral) of the amputation. In this review, we discuss the advantages and disadvantages of hand transplantation and prosthetic replacement for upper limb amputees in general, as well as in regard to the different levels of amputation.

Improved surgical and medical management has led to significant improvements in post-transplant survival rates with a 1 year and 5 year patient survival of 87% and 73%, respectively. A high mortality rate due to infections during the first post-transplant year persists. Invasive candidiasis is recognized as a significant problem associated with high morbidity and mortality. Recent surveillance data has helped to understand the changes in the epidemiology and the evolving trends in the use of antifungal agents for prophylaxis and treatment combined with the challenges of managing these invasive fungal infections, which has led the transplant community to explore the best management strategies. The emergence of resistant fungi and excess costs in managing these invasive fungal infections has added to the complexities of management. In this context, current perspectives in the management of Candida infections in liver transplant recipients will be reviewed. Keywords: Candida infections, management, liver transplant

    We present the characteristics and outcomes of heart transplantation in Spain since it was first performed in 1984. A descriptive analysis of the characteristics of recipients, donors, the surgical procedure, and the outcomes of heart transplantations performed in Spain until 31 December 2014. In 2014, 266 procedures were performed, making a time series of 7289 transplantations. The temporal analysis confirmed a significant worsening of the clinical profile of recipients (higher percentage of older patients, patients with severe renal failure, insulin-dependent diabetes, previous cardiac surgery, and previous mechanical ventilation), of donors (higher percentage of older donors and greater weight mismatch), and of the procedure (higher percentage of emergency transplantations, reaching 41.4% in 2014, and ischemia time>240min). Mechanical assist devices were used less than in 2013; in 2014 they were used in 18.8% of all transplant recipients. Survival at 1, 5, 10, and 15 years was 76%, 65%, 52%, and 38%, respectively, and has remained stable since 1995. Cardiac transplantation activity in Spain has remained stable in recent years, at around 250 procedures per year. Despite a clear deterioration in donor and recipient characteristics and surgical times, the mortality outcomes have remained comparable to those of previous periods in our environment. The growing use of circulatory assist devices before transplantation is also confirmed. Copyright © 2015 Sociedad Española de Cardiología. Published by Elsevier España, S.L.U. All rights reserved.

    Surgeons choose their profession with a strong desire to excel at manual therapeutic skills. Although we mime our mentors, we have often received the torch of technique in the absence of a systematic program to optimally develop our manual dexterity. The operating room is the ultimate arena to refine one's technical ability, but a surgical skills laboratory should assume increasing importance in introducing the trainee to the many nuances of the fine manual motor skills necessary for optimal surgical technique. Surgical educators should address the science of surgical handicraft in a manner similar to the science of preoperative and postoperative surgical principles that have been espoused over the past 40 years. Although it has been euphemistically said that "you can teach a monkey to operate," few of us have broken the process down into the basic elements to accomplish such a goal. In view of the increasing complexity of operations and equipment, the constraints on animal laboratories and teaching caseloads, and the mounting economic and medico-legal pressures, the development of optimal surgical skills should be a major objective of every surgical training program. By developing novel programs and scientifically evaluating the results of such endeavors, surgical faculties may find increased academic rewards for being a good teacher.

  10. Immune System and Kidney Transplantation.

    Science.gov (United States)

    2017-01-01

    The immune system recognises a transplanted kidney as foreign body and mounts immune response through cellular and humoral mechanisms leading to acute or chronic rejection, which ultimately results in graft loss. Over the last five decades, there have been significant advances in the understanding of the immune responses to transplanted organs in both experimental and clinical transplant settings. Modulation of the immune response by using immunosuppressive agents has led to successful outcomes after kidney transplantation. The paper provides an overview of the general organisation and function of human immune system, immune response to kidney transplantation, and the current practice of immunosuppressive therapy in kidney transplantation in the United Kingdom.

    Increased numbers of end-stage heart failure patients and improved technology have led to increased use of left ventricular assist devices as a viable alternative to heart transplants. Given the current economic climate, we compared costs of heart transplant versus device placement. Medical records of patients who received heart transplants or left ventricular assist devices were cross-referenced with institutional financial data. The device cohort was limited to those receiving durable (not temporary) devices. Index admission, 1-year readmission, and overall 1-year charges were compared using standard statistical methods. Of 184 identified patients with end-stage heart failure surgical therapy, 121 received left ventricular assist devices, 43 had heart transplants, and 20 received left ventricular assist devices as bridge to heart transplant; these latter patients were excluded from our analyses. At index admission, mean charges were $863 433 ± $398 427 for device patients and $725 877 ± $488 685 for transplant patients (P = .05). One-year mean readmission rates were similar (4.65/transplant patient and 4.53/device patient; P = .94), with corresponding 1-year survival rates of 87.8% and 78.0% (P = .04). Total readmission charges during year 1 were $169 732 ± $242 366 for device patients and $201 682 ± $297 565 for transplant patients (P = .08), with corresponding overall charges at 1 year of $1 029 732 ± $450 498 and $927 559 ± $562 404 (P = .49). During the first year, heart transplant and left ventricular assist device placement have similar costs. Initial index admission costs seem to favor heart transplant, with device pump costs accounting for some of the difference. From a 1-year survival perspective, heart transplant may be more effective; however, with lack of suitable donors, left ventricular assist devices are valuable in the armamentarium of advanced heart failure surgical options.

    Combined en bloc liver/pancreas transplantation (CLPT) was used primarily in the treatment of otherwise non-resectable upper abdominal malignancy. In fact, a more appropriate indication is in patients with liver disease and insulin-dependent diabetes mellitus (IDDM). Here, we report on two successful cases of CLPT at our hospital. One was a patient with non-resectable advanced liver cancer. The recipient survived for 23 mo and finally died of recurrent tumor. The other was a patient with severe biliary complication after orthotopic liver transplantation and preoperative IDDM. We performed CLPT with a modified surgical technique of preserving the native pancreas. He is currently liver-disease- and insulin-free more than 27 mo post-transplant. Based on our experience in two cases of abdominal cluster transplantation, we describe the technical details of CLPT and a modification of the surgical procedure. PMID:19469010

  13. Prostate cancer in renal transplant recipients

    Directory of Open Access Journals (Sweden)

    Benjamin A. Sherer

    Full Text Available ABSTRACT As patients with end-stage renal disease are receiving renal allografts at older ages, the number of male renal transplant recipients (RTRs being diagnosed with prostate cancer (CaP is increasing. Historically, the literature regarding the management of CaP in RTR's is limited to case reports and small case series. To date, there are no standardized guidelines for screening or management of CaP in these complex patients. To better understand the unique characteristics of CaP in the renal transplant population, we performed a literature review of PubMed, without date limitations, using a combination of search terms including prostate cancer, end stage renal disease, renal transplantation, prostate cancer screening, prostate specific antigen kinetics, immuno-suppression, prostatectomy, and radiation therapy. Of special note, teams facilitating the care of these complex patients must carefully and meticulously consider the altered anatomy for surgical and radiotherapeutic planning. Active surveillance, though gaining popularity in the general low risk prostate cancer population, needs further study in this group, as does the management of advance disease. This review provides a comprehensive and contemporary understanding of the incidence, screening measures, risk stratification, and treatment options for CaP in RTRs.

    Although over the past decade the management of invasive fungal infection has improved, considerable controversy persists regarding antifungal prophylaxis in solid organ transplant recipients. To identify the key clinical knowledge and make by consensus the high level recommendations required for antifungal prophylaxis in solid organ transplant recipients. Spanish prospective questionnaire, which measures consensus through the Delphi technique, was conducted anonymously and by e-mail with 30 national multidisciplinary experts, specialists in invasive fungal infections from six national scientific societies, including intensivists, anesthetists, microbiologists, pharmacologists and specialists in infectious diseases that responded to 12 questions prepared by the coordination group, after an exhaustive review of the literature in the last few years. The level of agreement achieved among experts in each of the categories should be equal to or greater than 70% in order to make a clinical recommendation. In a second term, after extracting the recommendations of the selected topics, a face-to-face meeting was held with more than 60 specialists who were asked to validate the pre-selected recommendations and derived algorithm. Echinocandin antifungal prophylaxis should be considered in liver transplant with major risk factors (retransplantation, renal failure requiring dialysis after transplantation, pretransplant liver failure, not early reoperation, or MELD>30); heart transplant with hemodialysis, and surgical re-exploration after transplantation; environmental colonization by Aspergillus, or cytomegalovirus (CMV) infection; and pancreas and intestinal transplant in case of acute graft rejection, hemodialysis, initial graft dysfunction, post-perfusion pancreatitis with anastomotic problems or need for laparotomy after transplantation. Antifungal fluconazole prophylaxis should be considered in liver transplant without major risk factors and MELD 20-30, split or living

    Meniscal pathology in skeletally immature patients includes meniscal tears and discoid lateral meniscus. Total or subtotal meniscectomy may occur in patients with discoid lateral meniscus or severe meniscal tears. Meniscal transplantation may be an option in skeletally immature patients status after total or subtotal meniscectomy with knee symptoms or dysfunction. This study focuses on the surgical technique and short-term outcomes of meniscus transplantation in skeletally immature patients. We reviewed our clinical database for skeletally immature patients who had undergone meniscus transplantation with a minimum of 2 years of follow-up. Patients were contacted, invited for a physical exam, and asked to complete a Pedi-IKDC, Lysholm, and Tegner outcomes questionnaire. The study protocol was approved by the responsible institutional review board. Three patients (two females/one male) were eligible for the study, each of whom responded to our invitation indicating availability for physical exam and questionnaire. Two patients had undergone subtotal discoid meniscus resection, leading to early lateral compartment degeneration. One patient developed advanced degeneration after a delay in treatment for a medial bucket-handle tear associated with anterior cruciate ligament rupture. The mean age of the patients at the time of surgery was 12.6±2.3 years. At a mean follow-up of 31±20 months, the mean Pedi-IKDC score was 68.3±4, the mean Lysholm was 55.7±22.3, and the median Tegner was 7 points. There were no indications of growth deformity during the regular postoperative radiological assessments. One patient required subsequent lysis of adhesions along the lateral mini arthrotomy and mobilization under anesthesia. The other two patients were able to return to sports at the same level as before meniscus transplantation and were able to do so within 9 months postoperatively. Over-resection of discoid menisci as well as untreated meniscus injury, the latter typically in

    Bone marrow transplantation is now an accepted form of therapy for many hematologic disorders including aplastic anemia, genetically determined diseases and malignant diseases, particularly leukemia, and for rescue of patients given intensive chemoradiotherapy for malignant disease. The donor may be a healthy identical twin, a family member or even an unrelated person. Selection is made on the basis of human leukocyte antigen tissue typing. Intensive chemoradiotherapy is used to suppress patients' immune systems to facilitate engraftment and destroy diseased marrow. Transfusion of platelets, erythrocytes and granulocytes (or all of these), antibiotic coverage and protection from infection are necessary during the pancytopenic period. Survival rates vary considerably depending on a patient's disease, clinical state and age. Patients with aplastic anemia transplanted early in the course of their disease have a survival rate of approximately 80%. Patients with acute lymphoblastic leukemia are usually transplanted in a second or subsequent remission and have a survival rate of 25% to 40%. Patients with acute nonlymphoblastic leukemia in remission have survivals ranging from 45% to 70%. More than 200 patients in the chronic phase of chronic granulocytic leukemia have been transplanted with survival ranging from 50% to 70%. Complications of marrow transplantation include marrow graft rejection, graft-versus-host disease, immunologic insufficiency and the possibility of recurrence of the leukemia. 14 references

  20. Heart Transplantation in Asia.

    2017-04-25

    Heart transplantation (HTx) is the effective way to improve quality of life as well as survival in terminal heart failure (HF) patients. Since the first heart transplant in 1968 in Japan and in earnest in 1987 at Taiwan, HTx has been continuously increasing in Asia. Although the current percentage of heart transplants from Asia comprises only 5.7% of cases in the International Society of Heart and Lung Transplantation (ISHLT) registry, the values were under-reported and soon will be greatly increased. HTx in Asia shows comparable with or even better results compared with ISHLT registry data. Several endemic infections, including type B hepatitis, tuberculosis, and cytomegalovirus, are unique aspects of HTx in Asia, and need special attention in transplant care. Although cardiac allograft vasculopathy (CAV) is considered as a leading cause of death after HTx globally, multiple observations suggest less prevalence and benign nature of CAV among Asian populations. Although there are many obstacles such as religion, social taboo or legal process, Asian countries will keep overcoming obstacles and broaden the field of HTx.

Compared with rapamycin, everolimus is characterized by a shorter half-life and improved bioavailability. Prior to US Food and Drug Administration approval, a number of Phase II and III clinical trials were undertaken to evaluate the effectiveness of everolimus in combination with calcineurin inhibitors for preventing acute rejection and promoting allograft survival in kidney transplant recipients. In this report, we review the pharmacokinetic properties of everolimus, the clinical efficacy studies that led to its approval for use in kidney transplantation, as well as reported data on patient safety and tolerability associated with its use.Keywords: mTOR inhibitors, kidney transplantation, everolimus

  2. Predicting Alloreactivity in Transplantation

    Full Text Available Human leukocyte Antigen (HLA mismatching leads to severe complications after solid-organ transplantation and hematopoietic stem-cell transplantation. The alloreactive responses underlying the posttransplantation complications include both direct recognition of allogeneic HLA by HLA-specific alloantibodies and T cells and indirect T-cell recognition. However, the immunogenicity of HLA mismatches is highly variable; some HLA mismatches lead to severe clinical B-cell- and T-cell-mediated alloreactivity, whereas others are well tolerated. Definition of the permissibility of HLA mismatches prior to transplantation allows selection of donor-recipient combinations that will have a reduced chance to develop deleterious host-versus-graft responses after solid-organ transplantation and graft-versus-host responses after hematopoietic stem-cell transplantation. Therefore, several methods have been developed to predict permissible HLA-mismatch combinations. In this review we aim to give a comprehensive overview about the current knowledge regarding HLA-directed alloreactivity and several developed in vitro and in silico tools that aim to predict direct and indirect alloreactivity.

    Full Text Available In the current situation of the shortage of suitable donor organs, heart transplantation from older donors is one of the ways to increase the performance of more heart transplants, particularly, in patients with urgent need of transplantation. While planning a heart transplantation from older donor one should consider increased risk of early cardiac allograft dysfunction, preexisting coronary artery disease, accelerated transplant vasculopathy which may adversely affect early and long-term survival of recipients. Subject to careful selection of donor–recipient pairs, effective prevention and treatment of early cardiac allograft dysfunction, pre-existing atherosclerosis and transplant vasculopathy the early and long-term survival of heart transplant recipients from older donors is comparable to heart transplantation from young donors.

    Full Text Available Background: Obesity is associated with increased surgical complications and long-term cardiovascular mortality. Studies of access in kidney transplantation have found a bias against obese patients on the wait-listing. Objective: To determine the current state of clinical practice for the management of obesity in kidney transplantation. Design: A survey in two versions, PDF and traditional paper, composed of categorical questions. Setting: A pan-Canadian survey of transplant nephrologists and surgeons. Methods: The survey PDF was distributed electronically to the Kidney Group of the Canadian Society of Transplantation. A shorter, hardcopy version was distributed subsequently at a national transplant meeting. Results: There were 47 responses, including almost every Canadian adult transplant program. Most (81% reported the use of a body mass index limit for access to the waiting list. However, only 40% reported a strict enforcement. There were several instances of intra-hospital disagreements regarding the use of a policy, among the centers with multiple responses. The body mass index limit was most commonly 40 kg/m 2 (62%, followed by 35 kg/m 2 (36%. Despite the body mass index limit, few centers (30% reported having a weight management program. The reported experience with bariatric surgery was small, though nearly all replied that they would refer to a bariatric specialist in the future. Limitations: This national survey provides a broad assessment of clinical practice. The distinction between an official policy and informal clinical tendencies is difficult.

    Cystic duct remnant mucocele is an extremely rare complication of liver transplantation in children. Surgical correction is usually required for cystic duct remnant mucocele when it causes biliary obstruction. We describe a 14-month-old liver transplant recipient who presented with biliary obstruction 1 month after orthotopic liver transplantation with an end-to-end choledochocholedocal biliary anastomosis for hepatoblastoma. US, CT and cholangiography findings were consistent with mucocele of the allograft cystic duct remnant. Surgery was not needed in our patient because the mucocele and biliary obstruction had resolved on repeat imaging most likely due to guidewire manipulation during cholangiography, resulting in opening of the cystic duct remnant orifice and drainage into the common duct.

    The latest high-throughput sequencing technologies show that there are more than 1000 types of microbiota in the human gut. These microbes are not only important to maintain human health, but also closely related to the occurrence and development of various diseases. With the development of transplantation technologies, allogeneic transplantation has become an effective therapy for a variety of end-stage diseases. However, complications after transplantation still restrict its further development. Post-transplantation complications are closely associated with a host's immune system. There is also an interaction between a person's gut microbiota and immune system. Recently, animal and human studies have shown that gut microbial populations and diversity are altered after allogeneic transplantations, such as liver transplantation (LT), small bowel transplantation (SBT), kidney transplantation (KT) and hematopoietic stem cell transplantation (HTCT). Moreover, when complications, such as infection, rejection and graft versus host disease (GVHD) occur, gut microbial populations and diversity present a significant dysbiosis. Several animal and clinical studies have demonstrated that taking probiotics and prebiotics can effectively regulate gut microbiota and reduce the incidence of complications after transplantation. However, the role of intestinal decontamination in allogeneic transplantation is controversial. This paper reviews gut microbial status after transplantation and its relationship with complications. The role of intervention methods, including antibiotics, probiotics and prebiotics, in complications after transplantation are also discussed. Further research in this new field needs to determine the definite relationship between gut microbial dysbiosis and complications after transplantation. Additionally, further research examining gut microbial intervention methods to ameliorate complications after transplantation is warranted. A better understanding of the

    Medical imaging plays a key role in solid organ donation and transplantation. In addition to confirming the clinical diagnosis of brain death, imaging examinations are used to assess potential organ donors and recipients, evaluate donated organs, and monitor transplantation outcomes. This article introduces the history, biology, ethics, and institutions of organ donation and transplantation medicine. The article also discusses current and emerging imaging applications in the transplantation field and the controversial role of neuroimaging to confirm clinically diagnosed brain death.

    2010-01-01

    The liver transplant waiting list is designed to allocate livers to the sickest patients first. Before March 1, 2002, livers were allocated to patients based on objective clinical indicators and subjective factors. In particular, a center placing a prospective transplant recipient in the intensive care unit (ICU) leads to a higher position on the liver transplant waiting list. After March 1, 2002, a policy reform mandated that priority on the liver transplant waiting list no longer be influen...

  14. Tolerogenic therapies in transplantation

    Directory of Open Access Journals (Sweden)

    2012-07-01

    Full Text Available Since the concept of immunologic tolerance was discovered in the 1940s, the pursuit of tolerance induction in human transplantation has led to a rapid development of pharmacologic and biologic agents. Short-term graft survival remains an all-time high, but successful withdrawal of immunosuppression to achieve operational tolerance rarely occurs outside of liver transplantation. Collaborative efforts through the NIH sponsored Immune Tolerance Network and the European Commission sponsored Reprogramming the Immune System for Establishment of Tolerance consortia have afforded researchers opportunity to evaluate the safety and efficacy of tolerogenic strategies, investigate mechanisms of tolerance, and identify molecular and genetic markers that distinguish the tolerance phenotype. In this article, we review traditional and novel approaches to inducing tolerance for organ transplantation, with an emphasis on their translation into clinical trials.

    BACKGROUND: Graft loss after liver transplantation remains a significant problem, especially in pediatric patients. The aim of this study was to assess our initial series of pediatric liver transplantation and to identify the risk factors that influence graft outcome. METHODS: The first 51...... transplantations were analyzed retrospectively. All transplantations were stratified into three groups according to graft type (full-size, reduced-size, and living-related-donor graft). Survival data of the grafts were stratified and multivariate analysis conducted with respect to preoperative and surgical factors....... RESULTS: Seventeen of all the transplants were full-size grafts and 34 technical-variant grafts (27 reduced-size grafts from cadavers and 7 living-related-donor grafts). The overall graft survival rates were 65, 62 and 53% at 1, 3 and 5 years, respectively. Twenty-three of 51 grafts (45%) were lost. Poor...

    The aim of our study was to evaluate the rate of surgical complications, patient outcomes, and impact on graft function in renal transplant recipients in whom cholecystectomy for acute cholecystitis was performed. We reviewed data on transplant patients from January 1, 2006, to December 31, 2013. The subgroup of patients who required subsequent cholecystectomy for acute cholecystitis was assessed, and their data were further analyzed. Thirty-one patients who underwent cholecystectomy for acute cholecystitis after renal transplantation were included in the study. Clinical signs such as pain in the right upper quadrant, temperature >38°C, and elevation in bilirubin levels occurred in 20 (64.5%), 8 (25.8%), and 3 (9.7%) patients, respectively. Ultrasound signs of acute cholecystitis were present in 27 patients (87.1%). In terms of laboratory values, white blood cell counts >10 × 10(9)/L occurred in 17 patients (54.8%), and C-reactive protein levels >40 mg/L were reported in 21 patients (67.7%). The conversion rate to open surgery was 32.3% (10 patients). In 13 cases, acalculous cholecystitis was present (41.9%). The average serum creatinine level 1 year after cholecystectomy had no statistically significant differences. One patient required temporary dialysis during the postoperative period (with subsequent graft recovery), and 1 graft was lost. Acute cholecystitis in kidney transplant recipients is a serious complication, with frequent difficulties related to evaluation and diagnosis. Because clinical signs could be very mild compared with severity of gallbladder affliction, there is little room if any for conservative treatment in these patients. We have not noticed adverse impact of acute cholecystitis on 1-year graft function. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Background/Aim. Multiple renal arteries (MRAs represent a surgical challenge by the difficulty in performing anastomoses, bleeding and stenosis. MRAs should be preserved and special attention should be paid to accessory polar arteries. All renal arteries (RAs must be reconstructed and prepared for safe anastomosis. The paper decribed the different techniques of vessel reconstruction during kidney transplantation including important steps within recovery of organs, preparation and implantation. Methods. In a 16-year period (1996-2012 of kidney transplantation in the Military Medical Academy, Belgrade, a total of 310 living donors and 44 human cadaver kidney transplantations were performed, of which 28 (8% kidneys had two or more RAs. Results. All the transplanted kidneys had immediate function. We repaired 20 cases of donor kidneys with 2 arteries, 4 cases with three RAs, one case with 4 RAs, one case with 4 RAs and renal vein reconstruction, one case with 3 arteries and additional polytetrafluoroethylene (PTFE graft reconstruction, one case with transected renal artery and reconstruction with 5 cm long deceased donor external iliac artery. There were no major complications and graft failure. At a minimum of 1-year follow-up, all the patients showed normal renal function. Conclusion. Donor kidney transplantation on a contralateral side and “end-to-end” anastomosis of the renal artery to the internal iliac artery (IIA is our standard procedure with satisfactory results. Renal artery reconstruction and anastomosis with IIA is a safe and highly efficient procedure and kidneys with MRAs are not contraindicated for transplantation. A surgical team should be fully competent to remove cadaveric abdominal organs to avoid accidental injuries of organs vessels.

    Forty-two MR studies, 162 radionuclide scintigraphic studies, and 57 sonographic studies were performed on 15 pancreatic transplant patients for evaluation of suspected graft rejection. The results of these studies were correlated with clinical presentations, laboratory data, and pathologic specimens when available. Radionuclide studies provide excellent information for estimating graft size and for evaluation of perfusion. Sonography is valuable for evaluation of the gland texture and peripancreatic abnormalities. MR provides useful information regarding parenchymal changes in rejection and response of the graft to treatment. These three imaging modalities are therefore complementary in the evaluation of pancreatic transplantation

    2011-01-01

    Full Text Available Scedosporium/Pseudallescheria species are frequently seen in cystic fibrosis patients. However, disseminated forms after lung transplantation in these patients are rarely seen, but often with poor outcome. In this case report we describe a lung transplant recipient with cystic fibrosis who developed a spondylodiscitis that was caused by Scedosporium apiospermum. The patient was treated with anti-fungal treatment by voriconazole for over three years with a clinical good response and without the need for surgical intervention. To our opinion this is the first anti-fungal treated case of invasive disease caused by Scedosporium/Pseudallescheria in a cystic fibrosis (CF patient who underwent lung transplantation that survived.

    Allograft meniscus transplant is considered as a treatment option for meniscus-deficient patients to provide pain relief and decrease contact stress. This procedure is now considered as safe and reliable for the treatment for knee pain after total menisectomy. This is a new technique that has been developed for arthroscopic meniscus transplant with no bone blocks. It anatomically recreates the meniscus-tibial insertions and provides aperture fixation of the meniscus horns. It is an alternative to the established bone block meniscus transplant technique and is less surgically invasive. V.

    Allograft thrombosis is a devastating early complication of renal transplantation that ultimately leads to allograft loss. We report here on our experience of nine cases of immediate re-transplantation following early kidney transplant thrombosis at a single centre between January 1990 and June 2009. The mean age was 42.9 years at time of transplant. For seven patients, the allograft thrombosis was their first kidney transplant and seven of the nine cases had a deceased donor transplant. The initial transplants functioned for a mean of 1.67 days and the patients received a second allograft at a mean of 3.1 days after graft failure. All of the re-transplants worked immediately. Four allografts failed after a mean of 52.5 months (2-155 months). Two of these died with a functioning allograft, one failed owing to chronic allograft nephropathy and one owing to persistent acute cellular rejection. The remaining five patients still have a functioning allograft after a mean of 101.8 months (7-187 months). One year allograft and patient survival after re-transplantation were 87.5% and 100% respectively (after 5 years, both were 57%). Immediate re-transplantation following early kidney transplant thrombosis can be a success. It may be considered in selected cases after allograft thrombosis.

    Full Text Available The current report describes two renal transplant recipients who presented with sporotrichosis. In addition, the authors review the general aspects of sporotrichosis in renal transplant recipients reported in the literature. Sporotrichosis is a rare fungal infection in transplant patients and has been reported primarily in renal transplant recipients not treated with antifungal prophylaxis. Extracutaneous forms of sporotrichosis without skin manifestations and no previous history of traumatic injuries have been described in such patients and are difficult to diagnose. Renal transplant recipients with sporotrichosis described in the present report were successfully treated with antifungal therapy including amphotericin B deoxycholate, lipid amphotericin B formulations, fluconazole and itraconazole.

    Marina Moguilevitch

    2018-01-01

    Full Text Available Domino liver transplant has emerged as a viable strategy to increase the number of grafts available for transplantation. In the domino transplant organs explanted from one patient are transplanted into another patient. The first successful domino liver transplant was performed in Portugal in 1995. Since then this innovative concept has been applied to several genetic or biochemical disorders that are treated by liver transplantation. An important consideration during this operation is that such livers can pose a risk of the de novo development of the disease in the recipient. That is why this surgical procedure requires careful planning, proper selection of the patients, and informed consent of both donor and recipient.

    2016-07-01

    Exhaustion of lymphocyte function through chronic exposure to a high load of foreign antigen is well established for chronic viral infection and antitumor immunity and has been found to be associated with a distinct molecular program and characteristic cell surface phenotype. Although exhaustion has most commonly been studied in the context of CD8 viral responses, recent studies indicate that chronic antigen exposure may affect B cells, NK cells and CD4 T cells in a parallel manner. Limited information is available regarding the extent of lymphocyte exhaustion development in the transplant setting and its impact on anti-graft alloreactivity. By analogy to the persistence of a foreign virus, the large mass of alloantigen presented by an allograft in chronic residence could provide an ideal setting for exhausting donor-reactive T cells. The extent of T cell exhaustion occurring with various allografts, the kinetics of its development, whether exhaustion is influenced positively or negatively by different immunosuppressants, and the impact of exhaustion on graft survival and tolerance development remains a fertile area for investigation. Harnessing or encouraging the natural processes of exhaustion may provide a novel means to promote graft survival and transplantation tolerance. © Copyright 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

    2016-01-01

    Full Text Available Nowadays, kidney transplantation is the best approach of renal replacement therapy for the majority of patients with end-stage renal disease that significantly improves the quality and length of life. Advances in the field of organ donation, immunosuppression, transplant surgery and immunology have improved short-term graft and patient survival. But the long-term graft survival remains static over last two decades. The disparity between low graft and high patient long-term survival led to increasing number of transplant recipients with failed grafts. Repeat renal transplant is presumed to be a good option for many patients losing their grafts, but it is associated with higher complication rates. Unfortunately, there are no evidence-based recommendations or guidelines for renal retransplantation procedure. This review is based on 100 scientifi c publications related to various aspects of the kidney retransplantation and provides the recent data on this matter.

    The functional and aesthetic outcome following application of conventional reconstructive procedures or prosthetic materials is not satisfactory, especially in patients who have severe deformities and disabilities. Since the first successful hand transplantation in France in 1998, composite tissue allograft transplantation has gained a great deal of interest in the field of plastic surgery. It is obvious that composite tissue allograft transplantation will improve patients' life quality, but this might be at the expense of decreasing life expectancy. Currently, the main obstacle for composite tissue allograft transplantation is the use of life-long immunosuppression therapy because of their well-known side effects. In addition, the ethical, social, and psychologic issues are raised when discussing face transplantation. The long-term results of the recently performed partial face transplantations will be critical to judge the future applications of partial or total face transplantation.

    2017-12-01

    The Gravity Recovery and Climate Experiment (GRACE) has recently celebrated its 15th anniversary. The aging of the satellites brings along new challenges for both mission operation and science data delivery. Since September 2016, the accelerometer (ACC) onboard GRACE-B has been permanently turned off in order to reduce the battery load. The absence of the information about the non-gravitational forces acting on the spacecraft dramatically decreases the accuracy of the monthly gravity field solutions. The missing GRACE-B accelerometer data, however, can be recovered from the GRACE-A accelerometer measurement with satisfactory accuracy. In the current GRACE data processing, simple ACC data transplant is used which includes only attitude and time correction. The full ACC data transplant, however, requires not only the attitude and time correction, but also modeling of the residual accelerations due to thruster firings, which is the most challenging part. The residual linear accelerations ("thruster spikes") are caused by thruster imperfections such as misalignment of thruster pair, force imbalance or differences in reaction time. The thruster spikes are one of the most dominant high-frequency signals in the ACC measurement. The shape and amplitude of the thruster spikes are unique for each thruster pair, for each firing duration (30 ms - 1000 ms), for each x,y,z component of the ACC linear acceleration, and for each spacecraft. In our approach, the thruster spike model is an analytical function obtained by inverse Laplace transform of the ACC transfer function. The model shape parameters (amplitude, width and time delay) are estimated using Least squares method. The ACC data transplant is validated for days when ACC data from both satellites were available. The fully transplanted data fits the original GRACE-B measurement very well. The full ACC data transplant results in significantly reduced high frequency noise compared to the simple ACC transplant (i.e. without

    Full Text Available Background: The gold standard treatment to replace missing tooth is dental implants, however, in certain cases, such as in young patients its placement is contraindicated. Autogenous tooth transplantation, which has been widely done in Scandinavian countries for many years, may become a good alternative to overcome this problem. Purpose: This article attempted to provide information about the indication, treatment planning, surgical technique and the successful result of autogenous tooth transplantation. Case: A fifteen year old male patient presented with large caries and periapical disease of his lower left first molar, which was partially erupted and the roots was not fully formed in radiograph. Case management: Autogenous tooth transplantation procedure was performed consisting of extraction of #36, odontectomy of #38 followed by its implantation to socket #36 and fixation of the transplanted tooth to the adjacent teeth. Post operative evaluation was done on regular basis within 18 months period. There was no complaint, the tooth was clinically stable and no evidence of periodontal problem. Serial radiographs showed healing of alveolar bone and periodontal tissue, and the complete root formation was evident by 18 months post operatively. Conclusion: Autogenous tooth transplantation is a potential alternative to replace extracted tooth. Provided that the case be properly planned and operation carefully performed, successful result of this treatment can be achieved.

    Orthotopic liver transplantation (OLT) is the only curative treatment for hepatic cirrhosis and is the most effective in the control of portal hypertension. The aim of this study was to analyze whether greater morbi-mortality is observed in patients undergoing liver transplantation with previous surgery for portal hypertension with respect to patients not having undergone this surgery. Different variables were analyzed in 2 groups of transplanted patients: one of 18 patients who had previously undergone surgery for portal hypertension and another group of 54 patients without this previous surgery. The following factors were studied: mean operative time and length of anahepatic phase, intraoperative consumption of concentrates of erythrocytes, fresh frozen plasma, units of platelets and cryoprecipitates, days of mechanical ventilation, stay in the ICU and total postoperative stay. No significant differences were observed (p < 0.05) in any of these factors or in survival. On analysis of the difficulty of surgical technique, postoperative evolution and survival and based on the variables described it may be concluded that previous surgery for portal hypertension does not only not contraindicate posterior liver transplantation, but rather may be useful in patients with an adequate hepative reserve presenting variceal hemorrhage since posterior transplantation does not present a worsened prognosis.

    A 53-year-old woman with liver cirrhosis and hepatocellular carcinoma underwent living donor liver transplantation. After transplantation, her hemoglobin and hematocrit levels decreased to 6.3 g/dl and 18.5%, respectively, during the course of 3 days. A contrast-enhanced abdominal computed axial tomography (CAT) scan showed a hemoperitoneum in the right perihepatic space with no evidence of abdominal wall hematoma or pseudoaneurysm formation. An angiogram of the deep circumflex iliac artery (DCIA) showed extravasation of contrast media along the surgical drain, which had been inserted during the transplantation procedure. Transcatheter embolization of the branches of the DCIA was successfully performed using N-butyl cyanoacrylate.

    Xenogeneic transplantation (XT) is the transplantation of organs or tissues from a member of one species to a member of another. Mammalian species frequently have circulating antibody which is directed against the foreign organ irrespective of known prior antigen exposure. This antibody may lead to hyperacute rejection once it ensues so efforts must be directed towards eliminating the pre-existing antibody. In those species in which hyperacute rejection of xenografts does not occur, cell-mediated refection, similar to allograft rejection, may occur. It is in the prevention of this latter form of refection that radiation is most likely to be beneficial in XT. Both total lymphoid irradiation (TLI) and selective lyphoid irradiation (LSI) have been investigated for use in conjunction with XT. TLI has contributed to the prolongation of pancreatic islet-cell xenografts from hamsters to rats. TLI has also markedly prolonged the survival of cardiac transplants from hamsters to rats. A more modest prolongation of graft survival has been seen with the use of TLI in rabbit-to-rat exchanges. Therapy with TLI, cyclosporine, and splenectomy has markedly prolonged the survival of liver transplants from hamsters to rats, and preliminary data suggest that TLI may contribute to the prolongation of graft survival in the transplantation of hearts from monkeys to baboons. SLI appears to have prolonged graft survival, when used in conjunction with anti-lymphocyte globulin, in hamster-to-rat cardiac graft exchanges. The current state of knowledge of the use of irradiaiton in experimental XT is reviewed. (author). 38 refs.; 1 fig.; 5 tabs

    Obesity is a major chronic disease affecting the U.S. population. Bariatric surgery has consistently shown greater weight loss and improved outcomes compared with conservative therapy. However, complications after bariatric surgery can be catastrophic, resulting in short bowel syndrome with a potential risk of intestinal failure, ultimately resulting in the need for a small bowel transplant. A total of 6 patients became dependent on home parenteral nutrition (HPN) after undergoing bariatric surgery at an outside facility. Four of the 6 patients required evaluation for small bowel transplant; 2 of the 6 patients were successfully managed with parenteral nutrition and did not require further small bowel transplant evaluation. Catheter-related bloodstream infection, a serious complication of HPN, occurred in 3 patients despite extensive patient education on catheter care and use of ethanol lock. Two patients underwent successful small bowel transplantation, 1 died before transplant could be performed, and 1 was listed for a multivisceral transplantation. Surgical procedures to treat morbid obesity are common and growing in popularity but are not without risk of serious complications, including intestinal failure and HPN dependency. Despite methods to prevent complications, failure of HPN may lead to the need for transplant evaluation. In selected cases, the best therapeutic treatment may be a small bowel transplant to resolve irreversible, post-bariatric surgery intestinal failure.

    Full Text Available Colorectal cancer (CRC is the third most incident cancer worldwide. Most of CRC patients will develop distant metastases, mainly to the liver, and liver resection is the only potential chance for cure. On the other hand, only a small proportion of patients with hepatic CRC metastasis are candidates for upfront liver resection. Liver transplantation (LT is an attractive option for patients with nonresectable CRC liver metastases (NRCLM without extrahepatic involvement. Initial experiences with LT for NRCLM achieved very poor outcomes, with a 5-year overall survival (OS lower than 20%. However, these initial studies did not have a standardized patient selection or neoadjuvant or adjuvant therapies. With recent advances in the surgical and medical oncology fields, the landscape has changed. Recent studies from Norway have shown an encouraging 5-year OS of 50% when transplanting patients with NRCLM. Nevertheless, the main concern when expanding the indications for LT is organ shortage. To manage this organ shortage, strategies utilizing live donor liver transplantation are gaining favor. A few ongoing trials are assessing the impact of LT in NRCLM patient survival. Therefore, the aim of this paper is to review the current status of LT for NRCLM.

Material and Methods. Results of 41 clinical studies (29799 patients with severe CHF were included in a meta-analysis. Data search was conducted in the following databases: Medline, Medscape, Pubmed, and websites dedicated to clinical research (National Institutes of Health, Clinical Center, ClinicalStudyResults.org, ClinicalTrials.gov. Results. As compared with pharmaceutical therapy, surgical treatment of severe CHF is better to reduce fatal risk, incidence of decompensation of CHF, frequency of cardiac arrhythmias, the need to perform or re-perform heart transplantation. It is also shown that CRT better reduced the mortality from progression of heart failure than heart transplantation. Both pharmaceutical therapy and surgical treatment improved functional class of CHF and quality of patients' life, but does not affect the left ventricular ejection fraction. Conclusion. It was found out that there was a number of significant advantages of surgical treatment of severe CHF, compared with pharmaceutical therapy. However, it is still a number of unresolved issues (particularly in relation to heart transplantation on the effectiveness comparing pharmaceutical and surgical therapies of severe CHF

    The generation, storage, transfer, and representation of image data in radiology are standardized by DICOM. To cover the needs of image guided surgery or computer assisted surgery in general one needs to handle patient information besides image data. A large number of objects must be defined in DICOM to address the needs of surgery. We propose an analysis process based on Surgical Workflows that helps to identify these objects together with use cases and requirements motivating for their specification. As the first result we confirmed the need for the specification of representation and transfer of geometric models. The analysis of Surgical Workflows has shown that geometric models are widely used to represent planned procedure steps, surgical tools, anatomical structures, or prosthesis in the context of surgical planning, image guided surgery, augmented reality, and simulation. By now, the models are stored and transferred in several file formats bare of contextual information. The standardization of data types including contextual information and specifications for handling of geometric models allows a broader usage of such models. This paper explains the specification process leading to Geometry Mesh Service Object Pair classes. This process can be a template for the definition of further DICOM classes.

    Tuberculosis is one of the leading infections after renal transplant, particularly in developing countries where the incidence and prevalence in the general population are high. Diagnosis requires bacteriologic and histologic confirmation. Interactions among the antitubercular drugs and the immunosuppressive agents have to be considered while prescribing, and surveillance for adverse effects is required. Although rare, case reports are available on extrapulmonary tuberculosis in allograft recipients. Here, we present a 25-year-old kidney transplant recipient who was diagnosed with lymph node tuberculosis under uncommon circumstances but who had a good outcome. This case report illustrates the difficulties in diagnosis of tuberculosis, changes in therapeutic protocols, and prognostic factors and highlights the effects of infectious complications with immunosuppressive therapy in this particular patient population.

    The past few years have witnessed a considerable shift in the clinical status of intestinal transplantation. A great deal of experience has been gained at the most active centers, and results comparable with those reported at a similar stage in the development of other solid-organ graft programs are now being achieved by these highly proficient transplant teams. Rejection and its inevitable associate, sepsis, remain ubiquitous, and new immunosuppressant regimes are urgently needed; some may already be on the near horizon. The recent success of isolated intestinal grafts, together with the mortality and morbidity attendant upon the development of advanced liver disease related to total parenteral nutrition, has prompted the bold proposal that patients at risk for this complication should be identified and should receive isolated small bowel grafts before the onset of end-stage hepatic failure. The very fact that such a suggestion has begun to emerge reflects real progress in this challenging field.

    Full Text Available Although current therapies for pretransplant desensitization and treatment of antibody-mediated rejection (AMR have had some success, they do not specifically deplete plasma cells that produce antihuman leukocyte antigen (HLA antibodies. Bortezomib, a proteasome inhibitor approved for the treatment of multiple myeloma (a plasma cell neoplasm, induces plasma cell apoptosis. In this paper we review the current body of literature regarding the use of this biological agent in the field of transplantation. Although limited experience with bortezomib may seem to show promise in the realm of transplant recipients desensitization and treatment of AMR, there is also experience that may suggest otherwise. Bortezomib's role in desensitization protocols and treatment of AMR will be defined better as more clinical data and trials become available.

  13. Pre-Liver Transplant: Tips Versus Distal Splenorenal Shunt

    Thomas W. Faust

    1997-01-01

    Full Text Available Recurrent variceal bleeding in liver transplant candidates with end-stage liver disease can complicate or even prohibit a subsequent transplant procedure (OLT. Endoscopic sclero-therapy and medical therapy are considered as first-line management with surgical shunts reserved for refractory situations. Surgical shunts can be associated with a high mortality in this population and may complicate subsequent OLT. The transjugular intrahepatic portosystemic shunt (TIPS has been recommended in these patients as a bridge to OLT. This is a new modality that has not been compared with previously established therapies such as the distal splenorenal shunt (DSRS. In this study we report our experience with 35 liver transplant recipients who had a previous TIPS (18 patients or DSRS (17 patients for variceal bleeding. The TIPS group had a significantly larger proportion of critically ill and Child-Pugh C patients. Mean operating time was more prolonged in the DSRS group (P=0.014 but transfusion requirements were similar. Intraoperative portal vein blood flow measurements averaged 2132±725 ml/min in the TIPS group compared with 1120±351ml/min in the DSRS group (P<0.001. Arterial flows were similar. Mean ICU and hospital stays were similar. There were 3 hospital mortalities in the DSRS group and none in the TIPS group (P=0.1. We conclude that TIPS is a valuable tool in the management of recurrent variceal bleeding prior to liver transplantation. Intra0Perative hemodynamic measurements suggest a theoretical advantage with TIPS. In a group of patients with advanced liver disease we report an outcome that is similar to patients treated with DSRS prior to liver transplantation. The role of TIPS in the treatment of nontransplant candidates remains to be clarified.

    Ever since the first liver transplant in the Republic of Moldova in 2013 we have performed 30 liver transplantations, the first having been performed in collaboration with the surgical team from Romania, led by Professor Irinel Popescu. The serious deficit of available cadaveric organs has forced us to begin with right hemi-liver transplantation from a living donor. In one third of liver transplantations we used right hemi-liver graft from a living donor, and in 2/3 of cases whole liver graft was harvested from brain-dead donors. The indication for surgical intervention in most cases was hepatic cirrhosis of viral aetiology in terminal stages, three cases of hepatocellular carcinoma, and one case for each of primary biliary cirrhosis, drug-induced toxic hepatitis, and liver retransplantation caused by hepatic arterial thrombosis. 10 cadaveric grafts were harvested from elderly donors ( 65 years). In the early postoperative period, four recipients died (2 live donor graft recipients and 2 graft recipients from donors with brain death). Causes of death were: intracerebral haemorrhage in the early postoperative period - 1, acute graft rejection - 1, hepatic artery thrombosis - 1, primary graft dysfunction - 1. There were no deaths during the late postoperative period. Of the complications that occurred during the early postoperative period we can highlight acute graft rejection -2, hepatic arterial thrombosis - 1, intraabdominal postoperative haemorrhage - 1, hepatic artery thrombosis -1, biliary peritonitis - 1, primary graft dysfunction -1, seizures -1. Complications during the postoperative period: biliary peritonitis after choledochal drainage removal - 1, "small-for-size" - 2. The accumulated experience and the use of modern technologies has allowed us to reduce the postoperative mortality rate, as well as the rate of occurring complications, in order to transfer this surgical intervention from the category of exclusivity operations to the category of daily

    We report on a patient diagnosed with disseminated (hepatic and pulmonary) tuberculosis in the context of immunosuppression following liver transplant. During the administration of anti-tuberculosis drugs an abrupt elevation of liver enzymes was detected leading us to suspect drug toxicity rather than graft rejection. Nevertheless, careful surveillance and adjustment of serum levels of immunosuppressant drugs permitted continuance of tuberculosis treatment with no further side effects.

    The theoretical model of coping mechanisms (CM), is based on a discussion between it's main determinant factors: individual and situational (related to the 2 approaches of coping: dispositional and constitutional). Actually the most used classification of CM is based on the division of CM in two main dimensions: coping focused on emotions and coping focused on problem resolution. It is essential that classification methods of CM have in consideration the coexistence of stable dispositional elements with a situational variability. Some instruments to evaluate CM are introduced, based on different theories. Coping can influence health threw different mechanisms (neuroendocrine system, health threatening behaviours and adherence) and is included in two of the more important theoretical models applied to health (Moos & Schafer's and Leventhal's). Based on a systematic literature review we concluded that the most prevalent CM in pre transplantation period are acceptance, active coping, seeking support, and the less used are self-blame and avoidance. In post transplantation period the more prevalent CM continue to be active coping and seeking support associated to confrontation, selfconfidence, religion and coping focused in the problem. Evasive, emotive and fatalistic CM are associated to less control sensed by patients. Confrontation is associated to a better quality of life and avoidance to a reduction of quality of life and higher depression levels and denial to non-adherence increase. Control sensed by patients, CM related to the expression of emotions and denial change threw clinical evolution of transplanted patients.

    Innate immunity is the first barrier against pathogen infection and has also the important function of activating the adaptive immunity. The receptors of innate immunity, such as toll-like receptors and other receptors, recognize as danger signals the molecular patterns of pathogens as well as those of endogenous molecules released by dying cells. The information is transmitted to adapter proteins that, through a chain of kinases that translate the signal to transcription factors regulating inflammatory genes. In the inflammatory milieu dendritic cells become mature, intercept the antigen and migrate to lymphoid organs where they present the antigen to naïve T cells. Complement also exerts an important role of bridge between innate and adaptive immunity. In donor-deceased kidney transplantation, the innate immunity is triggered in the donor by brain death and is aggravated by the cold ischemia and even more by reperfusion. Once activated, innate immunity produces a local inflammatory environment leading to dendritic cell maturation and complement activation. Dendritic cells present the alloantigen to T cells and induce their differentiation towards effector Th1 and Th17 while inhibiting Th2 and T regulatory cells. A main goal of the current research in transplantation is to obtain an immunological tolerance. Experimental studies showed the possibility of inducing operative tolerance in murine models and even in primates with the infusion of regulatory dendritic cells. However, there are no data with this technique in clinical transplantation.

    Full Text Available The role of infection with Mycoplasma hominis following cardiothoracic organ transplantation and its source of transmission have not been well-defined. Here, we identify and describe infection with M. hominis in patients following cardiothoracic organ transplantation after reviewing all cardiothoracic transplantations performed at our center between 1998 and July 2015. We found seven previously unreported cases of M. hominis culture positive infection all of whom presented with pleuritis, surgical site infection, and/or mediastinitis. PCR was used to establish the diagnosis in four cases. In two instances, paired single lung transplant recipients manifested infection, and in one of these pairs, isolates were indistinguishable by multilocus sequence typing (MLST. To investigate the prevalence of M. hominis in the lower respiratory tract, we tested 178 bronchoalveolar lavage (BAL fluids collected from immunocompromised subjects for M. hominis by PCR; all were negative. Review of the literature revealed an additional 15 cases of M. hominis in lung transplant recipients, most with similar clinical presentations to our cases. We recommend that M. hominis should be considered in post-cardiothoracic transplant infections presenting with pleuritis, surgical site infection, or mediastinitis. M. hominis PCR may facilitate early diagnosis and prompt therapy. Evaluation for possible donor transmission should be considered.

  8. Percutaneous Fixation of Anterior Column Acetabular Fracture in a Renal Transplant Recipient

    Full Text Available Renal transplantation, performed per million population, ranges from 30 to 60 in developed countries. The transplanted kidney is generally placed in iliac fossa; therefore the treatment procedure of the pelvic trauma in these patients should be selected carefully. The gold standard technique for the treatment of displaced acetabulum fractures is open reduction and internal fixation. Our patient had received a living-related-donor renal transplant due to chronic renal failure. In the second year of transplantation, she had been injured in a motor-vehicle accident, and radiographs showed a right acetabular anterior column fracture and left pubic rami fractures. The patient was treated with percutaneous fixation techniques and at one year of postoperative period there was no evidence of degenerative signs and the clinical outcome was good. Beside having the advantage of avoiding dissection through the iliac fossa by the standard ilioinguinal approach, percutaneous techniques, with shorter surgical time, decreasing soft tissue disruption, and the potential for early discharge from hospital might be ideal for a renal transplant recipient carrying a higher risk of infection. Percutaneous fixation of selected acetabular fractures in a renal transplant recipient would presumably have the potential to decrease the morbidity associated with traditional open surgical procedures.

    Full Text Available A rejeição do transplante de córnea é um processo imunológico celular de ataque a córnea transplantada que pode resultar em sua descompensação. É a causa mais comum de falência de transplantes. Os fatores de risco mais comuns para rejeição são a vascularização corneana, falência prévia por rejeição, sinéquias anteriores, botão doador grande ou descentrado, inflamação intra-ocular e cirurgias no segmento anterior. O quadro clínico é caracterizado por hiperemia, dor ocular, edema corneano e inflamação na câmara anterior. As rejeições podem ser classificadas em epitelial, subepitelial, estromal, endotelial, mista e em retransplantes. A prevenção de rejeições pode ser realizada através de técnica cirúrgica meticulosa, utilização de transplantes lamelares, histocompatibilidade receptor-doador e estratégias farmacológicas. Os corticosteróides são a terapia de escolha para o tratamento da rejeição de transplante de córnea e podem ser utilizados em diversas vias e dosagens. Os autores propõem protocolo de tratamento para rejeições.Corneal transplant rejection is an immunological cellular process that attacks the donor cornea and may cause its failure.

    Background Given the complexity of solid organ transplant recipients, a multidisciplinary approach is required. To promote medication safety and enable providers to focus on the medical and surgical needs of these patients, our department of pharmacy created a collaborative practice agreement between physicians and pharmacists. Through this agreement, credentialed pharmacists are empowered to provide inpatient services including initiation and adjustment of medications through independent review of laboratory results after multidisciplinary rounds. Objective To evaluate the effect of our collaborative practice agreement on clinical care and institutional finances. Setting An inpatient setting at a large academic medical center. Methods Three transplant pharmacists entered all clinical interventions made on abdominal transplant recipients between September and October 2013 into Quantifi ® , a software application that categorizes and assigns a cost savings value based on impact and type of intervention. Main outcome measure The main outcome measures in this study were number and categorization of interventions, as well as estimated cost savings to the institution. Results There were 1060 interventions recorded, an average of 20 interventions per pharmacist per day. The most common interventions were pharmacokinetic evaluations (36%) and dose adjustments (19%). Over the time period, these interventions translated into an estimated savings of $107,634.00, or an annual cost savings of $373,131.20 per pharmacist, or a cost-benefit ratio of 2.65 to the institution. Conclusions Based on our study, implementation of a collaborative practice agreement enables credentialed pharmacists to make clinically and financially meaningful interventions in a complex patient population.

  12. Tricuspid valve regurgitation after heart transplantation

    Science.gov (United States)

    Kwon, Murray H.

    2017-01-01

    Tricuspid valve regurgitation (TVR) in the orthotopic heart transplant (OHT) recipient is quite common and has varied clinical sequelae. In its severest forms, it can lead to right-sided failure symptoms indistinguishable from that seen in native heart TVR disease. While certain implantation techniques are widely recognized to reduce the risk of TVR in the cardiac allograft, concomitant tricuspid annuloplasty, while having advocates, is not currently accepted as a routinely established adjunct. Decisions to surgically correct TVR in the OHT recipient must be made carefully, as certain clinical scenarios have high risk of failure. Like in the native heart, anatomic etiologies typically have the greatest chances for success compared to functional etiologies. While repair options have been utilized, there is emerging data to support replacement as the more durable option. While mechanical prostheses are impractical in the heart transplant recipient, biologic valves offer the advantage of continued access to the right ventricle for biopsies in addition to acceptable durability in the low pressure system of the right side.

    Within the frame of this study it was investigated if it is possible - by means of nuclear medicine - to assess transplant function after xenogenic (heterologic) renal transplantation, to early diagnose complications and to observe organ function in follow-up examinations. The examination comprised camera-function-scintiscanning (=CFS), i.e. camera-sequence-scintiscanning (=CSS) and radio-isotope-nephrography (=RING), and the clearance measurement, which were carried out in parallel, as one operation. The clearance measurement based on tissue activity decrease graphs, which were registered by means of a body probe. Hippuran iodine 131 was used as radiopharmaceutical which usually is eliminated by the kidneys. In 112 examinations 33 dogs, who had received a fox kidney transplant, were investigated, starting on the day of surgical intervention until the transplant dysfunction was confirmed. These dogs had been treated in advance with immunosuppressive agents: a control group of 8 dogs, who received renal transplants of dingos, were not treated with immunosuppressants. The CFS as simultaneous realisation of CSS and of RING and the clearance measurement by means of hippuran iodine 131 achieved the examination aims. CSS permitted a sufficient survey over the individual functional phases. RING allows the early diagnosis of complications due to transplantation. The nuclear medical findings of camera-functional-scintiscanning and of clearance measurement show correspondence and they correspond also well to those findings resulting from traditional examination techniques which were applied in parallel. This procedure distinguishes itself not only by the diagnostic liability of nuclear medical examination methods, but also by its uncomplicated application, which permits the careful treatment of the dogs.

    Transplantation procedures using intraparenchymal injection of stem cells result in tissue injury in addition to associated surgical risks. Intravenous injection of mesenchymal stem cells gives engraftment to lesions, but the method has low efficiency and specificity. In traumatic brain injuries (TBI), there is a transient breakdown of the blood-brain barrier and an inflammatory response, which increase migration of cells from blood to parenchyma. The aim of this investigation was to analyze the effect of intra-arterial administration on cellular engraftment. Experimental TBI was produced in a rat model. Endovascular technique was used to administer human mesenchymal stem cells in the ipsilateral internal carotid artery. Evaluation of engraftment and side effects were performed by immunohistochemical analysis of the brain and several other organs. The results were compared to intravenous administration of stem cells. Intra-arterial transplantion of mesenchymal stem cells resulted in central nervous system (CNS) engraftment without thromboembolic ischemia. We observed a significantly higher number of transplanted cells in the injured hemisphere after intra-arterial compared to intravenous administration both 1 day (p<0.01) and 5 days (p<0.05) after the transplantation. Some cells were also detected in the spleen but not in the other organs analyzed. Selective intra-arterial administration of mesenchymal stem cells to the injured CNS is a minimally invasive method for transplantation. The method is significantly more efficient than the intravenous route and causes no side effects in the current model. The technique can potentially be used for repeated transplantation to the CNS after TBI and in other diseases. (orig.)

  19. Biomarkers in solid organ transplantation: establishing personalized transplantation medicine

    Science.gov (United States)

    2011-01-01

    Technological advances in molecular and in silico research have enabled significant progress towards personalized transplantation medicine. It is now possible to conduct comprehensive biomarker development studies of transplant organ pathologies, correlating genomic, transcriptomic and proteomic information from donor and recipient with clinical and histological phenotypes. Translation of these advances to the clinical setting will allow assessment of an individual patient's risk of allograft damage or accommodation. Transplantation biomarkers are needed for active monitoring of immunosuppression, to reduce patient morbidity, and to improve long-term allograft function and life expectancy. Here, we highlight recent pre- and post-transplantation biomarkers of acute and chronic allograft damage or adaptation, focusing on peripheral blood-based methodologies for non-invasive application. We then critically discuss current findings with respect to their future application in routine clinical transplantation medicine. Complement-system-associated SNPs present potential biomarkers that may be used to indicate the baseline risk for allograft damage prior to transplantation. The detection of antibodies against novel, non-HLA, MICA antigens, and the expression of cytokine genes and proteins and cytotoxicity-related genes have been correlated with allograft damage and are potential post-transplantation biomarkers indicating allograft damage at the molecular level, although these do not have clinical relevance yet. Several multi-gene expression-based biomarker panels have been identified that accurately predicted graft accommodation in liver transplant recipients and may be developed into a predictive biomarker assay.

  1. Surgical ethics: surgical virtue and more.

    Science.gov (United States)

    Vercler, Christian J

    2015-01-01

    The encounter between a patient and her surgeon is unique for several reasons. The surgeon inflicts pain upon a patient for the patient's own good. An operative intervention is irreducibly personal, such that the decisions about and performance of operations are inseparable from the idiosyncrasies of the individual surgeon. Furthermore, there is a chasm of knowledge between the patient and surgeon that is difficult to cross. Hence, training in the discipline of surgery includes the inculcation of certain virtues and practices to safeguard against abuses of this relationship and to make sure that the best interests of the patient are prioritized. The stories in this issue are evidence that in contemporary practice this is not quite enough, as surgeons reflect on instances they felt were ethically challenging. Common themes include the difficulty in communicating surgical uncertainty, patient-surgeon relationships, ethical issues in surgical training, and the impact of the technological imperative on caring for dying patients.

    Preemptive and postoperative pain management is part of patient care when performing extractions. Simple extractions can become complicated when tooth roots are fractured. Adequate lighting,magnification, and surgical techniques are important when per-forming surgical (complicated) extractions. Radiographs should be taken before extractions and also during the procedure to assist with difficult extractions. Adequate flap design and bone removal are necessary when performing surgical extractions. Complications, including ocular trauma, jaw fracture, and soft tissue trauma, are avoided or minimized with proper patient selection and technique.

    In this review, we provide a state of the art of liver transplantation in children, as the procedure is now carried out for more than 30 years and most of our paediatric colleagues are managing these patients jointly with liver transplant centres. Our goal for this article is to enhance the understanding of the liver transplant process that a child and his family goes through while explaining the surgical advances and the associated complications that could happen in the immediate or long-term follow-up. We have deliberately introduced the theme that 'liver transplant is a disease' and 'not a cure', to emphasise the need for adherence with immunosuppression, a healthy lifestyle and lifelong medical follow-up. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    2011-01-01

    Full Text Available Orthotopic liver transplantation is an important treatment option for patients with end-stage liver disease. Advances in surgical technique, along with improvements in organ preservation and immunosuppression have improved patient outcomes. Post-operative complications, however, can limit this success. Ultrasound is the primary imaging modality for evaluation of hepatic transplants, providing real-time information about vascular flow in the graft. Graft vascular complications are not uncommon, and their prompt recognition is crucial to allow for timely graft salvage. A multimodality approach including CT angiography, MRI, or conventional angiography may be necessary in cases of complex transplant vascular anatomy or when sonography and Doppler are inconclusive to diagnose the etiologies of these complications. The purpose of this article is to familiarize radiologists with the normal post-transplant vascular anatomy and the imaging appearances of the major vascular complications that may occur within the hepatic artery, portal vein, and venous outflow tract, with an emphasis on ultrasound.

    Full Text Available Laparoscopic renal autotransplantation has serious perturbations on the body's homeostasis due to its non physiological positioning, use of pneumoperitoneum, changing fluid strategy at different points of time and on-going steps to maintain optimal environment for the transplanted kidney. Generally speaking, the anaesthetic management of renal auto-transplantation by open technique is not very complex and the perioperative management can be categorized in the intermediate level of clinical skill requirement. Adding to the comfort of the anaesthesiologist is the fact that these patients are not in end stage renal disease state and does not manifest the comorbidities, multisystem involvement and technical complexities of long term renal dysfunction and renal replacement therapy. In our case report surgeons used the da Vinci surgical robotic system for laparoscopic transplantation of the kidney at a new site. In this article we discuss the anaesthetic challenges of robot assisted laparoscopic renal auto-transplantation along with a description of our index case.

    2015-01-01

    Full Text Available Fournier′s gangrene is not a common cause of morbidity in renal transplant recipients, but, if it occurs, it is difficult to treat because of the immunosuppression and associated increased mortality rate. We describe the case of a male patient who underwent renal transplantation with complicated post-operative course, resulting in cecum perforation (thermal injury due to cautery use during transplantation requiring exploratory laparotomy and cecostomy. A few days later, he developed Fournier′s gangrene and urgent radical surgical debridement of the scrotum was performed, along with aggressive antibiotic regimen and the immunosuppressive treatment was modified. Subsequently, the patient underwent scheduled cecostomy closure (right hemicolectomy, while the scrotum trauma healed with tertiary intention. Epidemiologic characteristics, clinical presentation, diagnostic workup, therapeutic options and morbidity-mortality rates of Fournier′s gangrene are reviewed, emphasizing the role of immunosuppression in renal transplant recipients to disease development.

    Laparoscopic resection of the transplanted kidney has been very rarely reported in the literature. On the one hand, this is due to the extremely low incidence of tumors of renal transplants. On the other hand, these patients are usually managed by open surgery due to difficulties in laparoscopic resection because of the scar tissue in the kidney area. Other options, though rarely performed, are cryosurgery and radiofrequency ablation of the tumor. In this article we report our own experience with a patient who underwent laparoscopic resection of renal transplant for renal cell carcinoma T1aN0M0 19 years after kidney transplantation. The tumor sized 27 cm was found incidentally by routine ultrasound. The operative time was 115 minutes, the renal ischemia time - 28 min. No intra- and postoperative complications were observed. Histological examination revealed renal cell carcinoma, surgical margins were negative. The patient was discharged on the 7th day after the surgery, no graft dysfunction was observed.

    Primary closure is not always possible after pediatric multivisceral transplantation. Reepithelialization may require extended periods of postoperative time, which can be associated with significant morbidity. The objective was to accelerate secondary wound closure thereby minimizing infection or further complications in a pediatric multivisceral transplant patient. Five applications of human fibroblast-derived dermis (Dermagraft, Smith and Nephew) were applied to the postsurgical defect of a pediatric multivisceral transplant patient over the course of 8 months. Routine wound care and observation was performed between human fibroblast-derived dermis applications. Human fibroblast-derived dermis stimulated healing and accelerated reepithelialization. Signs of clinical rejection or infection were not observed. Reepithelialization can be aided in the postoperative period in pediatric multivisceral transplant patients with human fibroblast-derived dermis, thereby helping to deter complications associated with secondary wound closure. We have illustrated the successful use of a human fibroblast-derived dermis as an adjunct for wound healing in a complicated surgical defect.

    Transplant tourism entails movement of recipient, donor or both to a transplant centre outside their country of residence. This has been reported in many countries; and has variously been associated with organ trade. The objective of this study is to determine the frequency and pattern of transplant tourism among transplant patients in Eastern Nigeria. This is a non randomized cross sectional study. All kidney transplant patients who presented at Enugu State University Teaching Hospital Parklane Enugu and Hilton Clinics Port Harcourt in Nigeria were recruited. The clinical parameters including the transplant details of all the patients were documented. The data obtained was analysed using SPSS package. A total of one hundred and twenty six patients were studied, 76.2% were males with M:F ratio of 3.2:1 and mean age of 46.9 ± 13.3 years. Fifty four and 58.7% of the patients were managed in a tertiary hospital and by a nephrologist respectively before referral for kidney transplant. Only 15.8% of the patients had their kidney transplant without delay: finance, lack of donor, logistics including delay in obtaining travelling documents were the common causes of the delay. Ninety percent of the patients had their transplant in India with majority of them using commercial donors. India was also the country with cheapest cost ($18,000.00). 69.8% were unrelated donors, 68.2% were commercial donors and 1.6% of the donors were spouse. All the commercial donors received financial incentives and each commercial donor received mean of 7580 ± 1280 dollars. Also 30.2% of the related donors demanded financial incentive. Transplant tourism is prevalent in eastern Nigeria.

    To study the bacteremias and fungemias of the patients with solid organ transplantation (kidney or liver) and analyze the differences according to the type of graft. A prospective study included in a control program of bacteremias of a 1000-bed hospital and a follow up study of the infections of the patients who had undergone kidney transplantation (KT) (1985-1991) and liver transplantation (LT) (1988-1991) were carried out. One hundred thirty-one bacteremias and 5 fungemias, 75 in 62 patients with KT out of a total of 568 transplantations (11%) and 63 out of 54 patients with LT out of a total of 185 transplantations (29%) were identified. The prevalence of bacteremia in LT was greater (p enterobacterias (12 and 12, respectively), Pseudomonas sp. (14 and 6, respectively), Candida sp. (2 and 3, respectively) with similar rates in both transplants. The origin of bacteremia was; renal and urinary tract, most frequent in KT (21 and 2 respectively) (p = 0.001). The origin of bacteremia was: renal and urinary tract, most frequent in KT (21 and 2 respectively) (p < 0.001), intraabdominal and biliary tract, most frequent in LT (4 and 14, respectively) (p = 0.007); intravenous catheter, most frequent in LT (16 and 24 respectively) (p < 0.05); lung, most frequent in LT although without statistical significance (3 and 8, respectively), (p = NS), and finally, surgical wound (4 and 1, respectively) (p = NS). Seventeen patients died (14 with LT and 3 with KT). The incidence of bacteremia and the mortality related, was greater in LT than that observed in KT. The most frequent origin in KT was the kidney and urinary tract and the biliary and intraabdominal organs and the intravenous catheter were most prevalent in liver transplants. Staphylococcus sp was the most frequent germ in both types of transplantation and polymicrobian infection in liver transplants. Gram-negative germs caused higher mortality in liver transplantation.

    Emergent mechanical support for the failing ventricle, with eventual transfer for definitive care, is often required at non-transplant centers. Transfer for definitive care, in terms of bridge to transplant, may require ventricular assist device (VAD) placement at the primary institution or at the transplant center. Review of consecutive single transplant center referrals was conducted to decipher optimal management. From January 1997 to December 2000, 104 patients were transferred to the University of Pennsylvania Heart Failure/Transplant Service. Most were transferred from active cardiac surgical programs, with 56 patients having post-cardiotomy failure at the primary site. A VAD was placed in procedures done at the outside hospital (OSH) in 28 patients, most commonly (60%) an Abiomed device. Of the 76 patients that received a VAD at the transplant center (TxpC), 86% received a TCI or Thoratec device. Biventricular support was required in 34 patients. Overall survival was 57%, with 54 patients bridged to transplantation and 5 patients undergoing recovery. Patients having a VAD placed at the OSH had a 32% (9 of 28) survival, whereas at the TxpC survival was 65% (45 of 76) (p 1-year post-transplant. The most common cause of death was multi-system organ failure (19 of 45), followed by major neurologic event (15 of 45). Infection was the cause of death in only 6 patients. Left ventricular failure can be treated by emergent VAD placement. Overall survival is substantial if these patients are referred to a transplant center with multiple options. In contrast to previous reports, survival rates may be improved by earlier referral, before VAD placement at non-transplant centers and use of a VAD with longer-term capability.

    2004-05-01

    Technological change, decreased financial support for medical education, and social oversight (in the form of the "To Err Is Human" report, HIPPA, and reduced work hours) are forcing a rethinking of the traditional model of surgical education to improve patient safety. New approaches to evaluating surgical competence, such as objective assessment, in combination with new technologies, such as the Internet and surgical simulators, provide the tools to effect a revolution in surgical education and training. Competency based upon quantifiable criteria measures must replace the traditional subjective assessment. The implementation requires accurately defining the elements of training, establishing new quantifiable metrics, stringently measuring performance against criterion, and reporting outcomes throughout the career of a surgeon.

    2016-01-01

    The World Health Organization estimated that in 2014, over 600 million people met criteria for obesity. In 2011, over 30% of individuals undergoing kidney transplant had a body mass index (BMI) 35 kg/m2 or greater. A number of recent studies have confirmed the relationship between overweight/obesity and important comorbidities in kidney transplant patients. As with non-transplant surgeries, the rate of wound and soft tissue complications are increased following transplant as is the incidence of delayed graft function. These two issues appear to contribute to longer length of stay compared to normal BMI. New onset diabetes after transplant and cardiac outcomes also appear to be increased in the obese population. The impact of obesity on patient survival after kidney transplantation remains controversial, but appears to mirror the impact of extremes of BMI in non-transplant populations. Early experience with (open and laparoscopic) Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy support excellent weight loss (in the range of 50%-60% excess weight lost at 1 year), but experts have recommended the need for further studies. Long term nutrient deficiencies remain a concern but in general, these procedures do not appear to adversely impact absorption of immunosuppressive medications. In this study, we review the literature to arrive at a better understanding of the risks related to renal transplantation among individuals with obesity. PMID:27011911

  5. Informed consent in high-risk renal transplant recipients.

    Before performing a clinical, diagnostic, and/or therapeutic action, the doctor is required to provide the patient with a bulk of information defined as informed consent. This expression was used for the first time in 1957 during a court case in California and the two words--informed and consent--are used together to underline the fact that the patient cannot give his or her true consent without first receiving correct information concerning the medical act in question. With regard to the medicolegal aspects governing organ transplants, despite the bulk of detailed work performed by health service workers involved in this surgical field with the aim of preparing adequate informed consent models, this has not yet been accompanied by the necessary legislative development. The informed consent model to be presented to the kidney transplant candidate should include a detailed description of the recipient's comorbidity and should aim at reducing the number of medicolegal actions, which have become more and more frequent in the last few years due to the ever increasing number of patients considered as suitable for transplantation. Informed consent, therefore, should not be a mere bureaucratic formality to be obtained casually, but should be carefully stipulated together with the patient by the transplant surgeon. It is, in fact, an indispensable condition for transforming a potentially illegal action, that is, the violation of an individual's psychophysical integrity, into a legal one.

    The British government has printed 10 million organ donor cards--as well as posters, car stickers, and leaflets--for distribution in a campaign to increase the number of organ transplants in the United Kingdom. Norman Fowler, Secretary of State for Social Services, suggested at a February 22, 1984, press conference that signing of donor cards might become a family occasion, so that all concerned would know of a person's wishes in the event of sudden death. He made it clear that the government has no plans to introduce a system of presumed consent for organ donation. Mr. Fowler also announced a commitment of additional government funds for renal services.

    The oligochaete annelids Lumbricus terrestris and Eisenia foetida were used to demonstrate adoptive transfer of transplantation immunity. Eisenia grafts were used as sensitizing antigen and test grafts. Host Lumbricus injected with coelomic fluid containing coelomocytes from Lumbricus donors previously sensitized to Eisenia grafts rejected test grafts in an accelerated fashion. The rejection time was shorter and significantly different from that of worms injected with saline or coelomocytes from unsensitized worms. Coelomocytes resemble various vertebrate leucocytes and immunocytes and seem equivalent to a hypothetical invertebrate precursor wandering cell which recognizes and reacts to antigen.

    Fecal microbiota transplantation (FMT) has gained an increasing medical interest, since the recognition of the role of disturbed microbiota in the development of various diseases. To date, FMT is an established treatment modality for multiple recurrent Clostridium difficile infection (RCDI), despite lack of standardization of the procedure. Persisting normalization of the disturbed colonic microbiota associated with RCDI seems to be responsible for the therapeutic effect of FMT. For other diseases, FMT should be considered strictly experimental, only offered to patients in an investigational clinical setting. Although the concept of FMT is appealing, current expectations should be damped until future evidence arises. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Full Text Available Since its first description in 1992, laparoscopic adrenalectomy has become the gold standard for the surgical treatment of most adrenal conditions. The benefits of a minimally invasive approach to adrenal resection such as decreased hospital stay, shorter recovery time and improved patient satisfaction are widely accepted. However, as this procedure becomes more widespread, critical steps of the operation must be maintained to ensure expected outcomes and success. This article reviews the surgical techniques for the laparoscopic adrenalectomy.

  10. Liver transplantation for nontransplant physicians

    2014-01-01

    Full Text Available Many of the nontransplant physicians who manage hepatic patients (internists and hepatologists keep asking about liver transplantation. The purpose of this article is to highlight important topics a nontransplant colleague may require in his practice. There are many topics in this respect; however, three most important topics need to be highlighted; those are; the time of referral to transplantation, the indications and contraindications and the metabolic issues regarding a transplanted patient. Still, there are no clear guidelines for the management of many of the metabolic issues regarding liver transplanted patients. And this why, collaborative efforts of transplant and nontransplant physicians are needed to conduct multicenter, long term randomized controlled trials and proper follow up programs.

    2010-01-01

    INTRODUCTION: Kidney transplantation is the optimal treatment for many patients with end-stage renal disease (ESRD). Due to shortage of donor kidneys in Denmark, there is a need to expand the possibilities for donation. At the Odense University Hospital (OUH), we have introduced ABO......-incompatible kidney transplantation. We used antigenspecific immunoadsorptions to remove blood group antibodies and anti-CD20 antibody (rituximab) to inhibit the antibody production. The aim of introducing the ABO-incompatible kidney transplantation at the OUH was to increase the rate of living donor kidney...... transplantation without increasing rejection or mortality rates. MATERIAL AND METHODS: Retrospective evaluation. Eleven patients received ABO-incompatible kidney transplantation. The patients were followed for 3-26 months. RESULTS: One patient had an antibody-mediated rejection, one patient suffered T...

    We report the first two cases of posttransplant lymphoproliferative disorder (PTLD) in recipients of islet transplants worldwide. First, a 44-year-old recipient of three islet infusions developed PTLD 80 months after his initial transplantation, presenting with abdominal pain and diffuse terminal ileum thickening on imaging. He was treated with surgical excision, reduction of immunosuppression, and rituximab. Seven months later, he developed central nervous system PTLD, presenting with vertigo and diplopia; immunosuppression was discontinued, resulting in graft loss, and he was given high-dose methotrexate and underwent consolidative autologous stem cell transplantation. He remains in remission 37 months after the initial diagnosis. Second, a 58-year-old female recipient of two islet infusions developed PTLD 24 months after initial islet infusion, presenting with pancytopenia secondary to extensive bone marrow involvement. Immunosuppression was discontinued, resulting in graft loss, and she received rituximab and chemotherapy, achieving complete remission. Both patients were monomorphic B cell PTLD subtype by histology and negative for Epstein-Barr virus in tissue or blood. These cases document the first occurrences of this rare complication in islet transplantation, likely secondary to prolonged, intensive immunosuppression, and highlight the varying clinical manifestations of PTLD. Further studies are needed to determine incidence rate and risk factors in islet transplantation. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Kidney transplantation is the most cost-effective option for the treatment of end-stage renal disease, but the financial aspects of kidney transplantation have not yet been fully investigated. The purpose of this study was to determine the hospital cost of living donor kidney transplantation in China and to identify factors associated with the high cost. Demographic and clinical data of 103 consecutive patients who underwent living donor kidney transplantation from January 2007 to January 2011 at our center were reviewed, and detailed hospital cost of initial admission for kidney transplantation was analyzed. A stepwise multiple regression analysis was computed to determine predictors affecting the total hospital cost. The median total hospital cost was US $10,531, of which 69.2% was for medications, 13.2% for surgical procedures, 11.4% for para clinics, 3.7% for accommodations, 0.5% for nursing care, and 2.0% for other miscellaneous medical services. A multivariate stepwise logistic regression model for overall cost of transplantation revealed that the length of hospital stay, induction therapy, steroid-resistant rejection, maintenance therapy, infection status and body weight were independent predictors affecting the total hospitalization cost. Although the cost of living donor kidney transplantation in China is much lower than that in developed countries, it is a heavy burden for both the government and the patients. As medications formed the greater proportion of the total hospitalization cost, efforts to reduce the cost of drugs should be addressed.

  14. Matching donor to recipient in liver transplantation: Relevance in clinical practice.

    Achieving optimum outcomes after liver transplantation requires an understanding of the interaction between donor, graft and recipient factors. Within the cohort of patients waiting for a transplant, better matching of the donor organ to the recipient will improve transplant outcomes and benefit the overall waiting list by minimizing graft failure and need for re-transplantation. A PubMed search was conducted to identify published literature investigating the effects of donor factors such as age, gender, ethnicity, viral serology; graft factors such as size and quality, recipient factors such as age, size, gender and transplant factors such as major or minor blood group incompatibility and immunological factors. We also report technical and therapeutic modifications that can be used to manage donor-recipient mismatch identified from literature and the authors' clinical experience. Multiple donor and recipient factors impact graft survival after liver transplantation. Appropriate matching based on donor-organ-recipient variables, modification of surgical technique and innovative peri-transplant strategies can increase the donor pool by utilizing grafts from marginal donors that are traditionally turned down.

    Between February 26, 1981, and July 30, 1987, 36 patients underwent orthotopic liver transplantation for primary sclerosing cholangitis associated with ulcerative colitis. Three of the 36 recipients died within 3 mo because of graft nonfunction or surgical complications. The other 33 (92%) lived for at least 1 yr. Two of the 33 died after 12 and 14 mo, respectively, of recurrent cholangiocarcinoma that was not diagnosed before transplantation. Four other patients died of recurrent liver failure (three cases) or immunoblastic sarcoma (one case) after 14, 21, 36 and 44 mo. Twenty-seven (75%) of the patients are still alive 23 to 81 mo after transplantation. Two patients have been diagnosed as having colorectal cancer 11 and 21 mo respectively, after transplantation, for an overall incidence of 5.6% (2 of 36) and a corrected incidence of 6.5% (2 of 31) if the three early deaths and two later deaths caused by cholangio-carcinomas are excluded. It is not known whether colorectal malignancies were present but undetected at the time of transplantation or whether they developed afterward. It is clear that patients who undergo liver transplantation for primary sclerosing cholangitis associated with ulcerative colitis should have careful follow-up of the colon, including colonoscopy and multiple biopsies of the colorectal mucosa. Whether proctocolectomy should be considered prophylactically after liver transplantation is an unresolved issue. PMID:2312061

    A 31-year-old woman who had undergone surgery for a congenital cataract as a newborn developed bilateral malignant glaucoma, which was refractory to medical-surgical treatment. The patient currently has terminal glaucoma and severe band keratopathy. For aesthetic purposes, we performed intrastromal keratopigmentation surgery using ink for skin tattoos supplied in sterile single-dose vessels. No secondary effects or complications were observed. Keratopigmentation or corneal tattooing can now be used as a last resort in patients who are unable to tolerate cosmetic contact or intraocular lenses, or in whom corneal transplant is contraindicated.

    1995-03-01

    Heart transplantation is an established treatment modality for end-stage cardiac disease. Unfortunately, relative to other health care priorities, heart transplantation has fallen into disrepute. Efforts to reform the health care system have focused on three fundamental issues--cost, quality, and access. On each count, heart transplantation is vulnerable to criticism. Managed care is an incremental approach to health care reform that imposes fiscal constraint on providers. This constraint is expressed in the form of capitation which, in turn, requires providers to assume risk and accept economic responsibility for clinical decisions. While the need for transplantation is considerable, there are both clinical and economic factors limiting the overall level of activity. In 1993, over 2200 heart transplants were performed in the United States on people who were dying of end-stage cardiac disease. The total demand for heart transplantation was estimated to be about 5900 persons, which was not met due to an insufficient supply of donor hearts. Absent donors, the fiscal consequences of heart transplantation are minimized. In 1993, actuaries estimated that the total charge per heart transplant was $209,100. By designating centers based on price and quality considerations, managed care plans have reduced this per procedure expense to less than $100,000. While the benefits of transplantation are noteworthy, there are still concerns. Sixty percent of patients report that they are able to work, but only 30% do so. Employers hope to improve upon this record by expanding the designated center approach. In conclusion, the future of heart transplantation is unclear. Opportunities for innovation are limited, although the management of heart failure is an area of increased interest.

    To analyze and evaluate our experience in surgical treatment with the open approach of the complex ureteral stenosis after adult kidney transplantation in a tertiary level hospital in the last seven years. We have reviewed the different surgical options used. A total of 589 consecutive adult renal transplants were performed from January 2005 to December 2012. Of these, 1.1% showed some degree of symptomatic obstructive uropathy which after initial urinary diversion required open surgical approach using the ipsilateral or contralateral native urinary tract. Characteristics of the patient, clinical examinations performed and surgical technique performed as well as their results are presented. During the period under review, in 5 men and 2 women who had ureteral stenoses after renal transplant, 7 reparative surgeries were performed by open ureteropyelostomy, using ipsilateral native ureter in 6 cases and contralateral ureter in the remaining case. In one case, uretero-calicial anastomosis was performed due to severe pyelic shrinkage. There were no significant complications. Native kidney nephrectomy was not required for further complications. All the patients operated on had optimum plasma creatinine levels with resolution of previous dilatation. The initial percutaneous nephrostomy followed by open surgical repair using native ureter represents a definitive, valid and optimal alternative in terms of safety and preservation of renal function.

    Full Text Available Abstract Background High astigmatisms are usually induced during corneal suturing subsequent to tissue transplantation or any other surgery which involves corneal suturing. One of the reasons is that the procedure is intimately dependent on the surgeon's skill for suturing identical stitches. In order to evaluate the influence of the irregularity on suturing for the residual astigmatism, a prototype for ophthalmic surgical support has been developed. The final intention of this prototype is to be an evaluation tool for guided suture and as an outcome diminish the postoperative astigmatism. Methods The system consists of hand held ring with 36 infrared LEDs, that is to be projected onto the lachrymal film of the cornea. The image is reflected back through the optics of the ocular microscope and its distortion from the original circular shape is evaluated by developed software. It provides keratometric and circularity measurements during surgery in order to guide the surgeon for uniformity in suturing. Results The system is able to provide up to 23D of astigmatism (32D - 55D range and is ± 0.25D accurate. It has been tested in 14 volunteer patients intraoperative and has been compared to a commercial keratometer Nidek Oculus Hand-held corneal topographer. The correlation factors are 0.92 for the astigmatism and 0.97 for the associated axis. Conclusion The system is potentially efficient for guiding the surgeon on uniformity of suturing, presenting preliminary data indicating an important decrease on the residual astigmatism, from an average of 8D - for patients not submitted to the prototype guidance - to 1.4D - for patients who have actually been submitted to the prototype guidance - after the first 24 hours post-surgery and in the subsequent weeks. It also indicates that the surgeon should achieve circularity greater or equal to 98% in order to avoid postoperative astigmatisms over 1D.

    -directed therapy for surgical and infectious complications is frequently delayed because of the time taken to establish an accurate diagnosis. Refuting the existence of commercial renal transplantation may not be a practical solution; more consistent communication and documentation with transplant teams may be more pragmatic. In the current climate, patients considering the option of overseas commercial renal transplantation should be advised of the potential increased risks.

    2005-08-01

    The bad risk for an early onset of osteoarthritis in the knee increases with the size of a cartilage defect. A collateral meniscus- or ligament-tear will enforce this hazard in addition. In order to avoid such a development, relevant full-thickness cartilage defects should be reconstructed biologically and attendant meniscus- or ligament-tears as well as varus- or valgus deformities should be treated. A number of studies, including some prospective-randomized trials, have shown that autologous chondrocyte transplantation (ACT) is the most reliable procedure for a surgical treatment of full-thickness cartilage defects larger than 4 cm (2) in adults. One disadvantage of ACT is the extensive approach to the joint and often a hypertrophy of the repair tissue. To solve these problems, some different biomaterials for a matrix-assisted ACT have been developed. The scaffold we use has a covering membrane upside and a collagen-sponge carrying the chondrocytes. By means of special surgical instruments a minimally invasive implantation is possible, reducing the side-effects of an extensive approach. Animal studies showed the regeneration of a hyaline cartilage using our described system. However, results of current clinical studies with the different scaffolds must be awaited before an universal application of matrix-assisted ACT can be recommended.

    Kidney transplantation is the best treatment option for end-stage renal disease patients. Increased incidence of post-transplantation malignancy can be caused by immunosuppressive drugs and some oncogenic infections. The aim of this study is to show the incidence of post-transplantation malignancy in patients who had surgery and were followed up in the Organ Transplant Center, Medical Park Antalya, Antalya, Turkey. The study was based on 2100 kidney transplantation patients who had surgery between May 2008 and December 2012 and also on 1900 patients who had surgery by members of our team in other centers and who were followed up routinely. In all of our patients, the type of malignancy, the time that malignancy developed, immunosuppressive regimens, and viral status (Epstein-Barr virus and cytomegalovirus) were investigated. Malignancy was developed in 30 patients (60% of them were male, median age was 52.1 years). Post-transplantation malignancy development time was a median of 5.1 years. The types of malignancies were as follows: non-melanoma skin cancer in 12 patients (40%), urogenital cancer in 7 patients (24%), breast cancer in 4 patients (14%), lymphoproliferative disease in 3 patients (10%), thyroid cancer in 2 patients (6%), and lung cancer in 2 patients (6%). In this study, we did not find any increased post-transplantation malignancy risk in our patients. This finding could be due to the low-dosage immunosuppressive protocols that we used.

    2015-06-01

    Deceased donor organ procurement provides unparalleled opportunity for surgical residents with extensive surgical exposure. We hypothesize that surgical residents regard organ donation positively and organ procurement enhances their education. We conducted an institutional review board approved anonymous national survey to evaluate organ procurement experiences and attitudes of general surgical residents. Three hundred ninety-seven residents representing all postgraduate years responded, with 97% completion rate. Organ procurement increased with training level (92% seniors vs. 53% interns). Over 85% agree organ procurement is a good educational and operative experience, and 73% believe that it will benefit their future surgical career. About 68% agree that organ procurement provided knowledge of anatomy and exposures; under 10% felt organ procurement could be duplicated with simulation. Presence of transplant program did not affect attitudes or experience. Eighty-eight percent women versus77% men plan to donate their own organs. Results indicate that surgical residents value organ procurement, and it remains an essential encounter that applies to general surgery. Copyright © 2015 Elsevier Inc. All rights reserved.

    The postoperative diagnostic imaging examinations of 44 children who underwent 59 orthotopic liver transplantations were reviewed. The imaging modalities used for the evaluation of suspected complications include plain roentgenography, ultrasonography (US), computed tomography (CT), nuclear scintigraphy, arteriography, percutaneous and operative cholangiography, and endoscopic retrograde cholangiopancreatography. The main postoperative complications included ischemia, thrombosis (hepatic artery and portal vein), infarction, obstruction or leakage of the biliary anastomosis, hepatic and perihepatic infection, and allograft rejection. US, the most frequently used abdominal imaging modality, was best suited for detection of biliary duct dilatation, fluid collections in or around the transplanted liver, and hepatic arterial, inferior vena caval, and portal vein thrombosis. CT was especially helpful in corroborating findings of infection and in locating abscesses. Technetium 99m sulfur colloid (early- and late-phase imaging) provided a sensitive, although nonspecific, means of assessing allograft vascularization and morphology. Angiography showed vascularity most clearly, and cholangiography was the most useful In the assessment of bile duct patency. A diagnostic imaging algorithm is proposed for evaluation of suspected complications. PMID:3901104

    2010-09-01

    Concern has increasingly been expressed about the growing number of reports of medical personnel participating in the transplantation of human organs or tissues taken from the bodies of executed prisoners, handicapped patients, or poor persons who have agreed to part with their organs for commercial purposes. Such behavior has been universally considered as ethically and morally reprehensible, yet in some parts of the world the practice continues to flourish. The concept of justice demands that every person have an equal right to life, and to protect this right, society has an obligation to ensure that every person has equal access to medical care. Regrettably, the Egyptian system does not legally recognize brain death and continues to allow the buying and selling of organs. For more than 30 years in Egypt, the ability to pay has determined who receives an organ and economic need has determined who will be the donor. As transplant professionals, it is important that we advocate on behalf of all patients, potential recipients, and donors and for those who are left out and not likely to receive a donor organ in an economically based system. Current issues associated with this debate are reviewed and recommendations about how to address them in Egypt are discussed.

    In patients with advanced heart failure, morbid obesity is a relative contraindication to heart transplantation due to higher morbidity and mortality in these patients. We performed a retrospective analysis of consecutive morbidly obese patients with advanced heart failure who underwent bariatric surgery for durable weight loss in order to meet eligibility criteria for cardiac transplantation. Seven patients (4 M/3 F, age range 31-56 years) with left ventricular ejection fraction (LVEF) ≤ 25 % underwent laparoscopic bariatric surgery. Median preoperative body mass index (BMI) was 42.8 kg/m(2) (range 37.5-50.8). There were no major perioperative complications in six of seven patients. Median length of hospital stay was 5 days. There was no mortality recorded during complete patient follow-up. At a median follow-up of 406 days, median BMI reduction was 12.9 kg/m(2) (p = 0.017). Postoperative LVEF improved to a median of 30 % (interquartile range (IQR) 25-53 %; p = 0.039). Two patients underwent successful cardiac transplantation. Two patients reported symptomatic improvement with little change in LV function and now successfully meet listing criteria. Three patients showed marked improvement of their LVEF and functional status, thus removing the requirement for transplantation. Bariatric surgery can achieve successful weight loss in morbidly obese patients with advanced cardiac failure, enabling successful heart transplantation. In some patients, cardiac transplantation can be avoided through surgical weight loss.

    BACKGROUND Post-transplant lymphoproliferative disorder (PTLD) is a potential complication of solid organ or bone marrow transplants. The main PTLD risk factors are: the Epstein-Barr virus (EBV), transplant type, and use of immunosuppressants. It mainly consists of an uncontrolled growth of lymphocytes in transplant recipients under chronic immunosuppressive therapy. About 85% of PTLDs are EBV-containing B-cell proliferations; 14% are T-cell proliferations, of which only 40% contain EBV; and the remaining 1% is NK-cell or plasmocyte proliferations. PTLD may present various clinical manifestations, from non-specific mononucleosis-like syndrome to graft or other organ damage resulting from pathologic lymphocyte infiltration. PTLD may manifest in the oral cavity. CASE REPORT The objective of this study was to present the case of a 13-year-old female living-donor liver transplant recipient, resulting from biliary cirrhosis caused by congenital biliary atresia, with exophytic fibrous lesions on buccal mucosa and tongue. Exophytic and hyperplastic lesion of oral mucosa were removed and histopathological examination revealed polymorphic PTLD. The patient underwent 6 cycles of CHOP chemotherapy and all the oral lesions regressed completely. CONCLUSIONS All oral pathological lesions in organ transplant recipients need to be surgically removed and histopathologically examined because they present an increased risk of neoplastic transformations such as PTLD.

    Organ regenerative therapy aims to reproduce fully functional organs to replace organs that have been lost or damaged as a result of disease, injury, or aging. For the fully functional regeneration of ectodermal organs, a concept has been proposed in which a bioengineered organ is developed by reproducing the embryonic processes of organogenesis. Here, we show that a bioengineered hair follicle germ, which was reconstituted with embryonic skin-derived epithelial and mesenchymal cells and ectopically transplanted, was able to develop histologically correct hair follicles. The bioengineered hair follicles properly connected to the host skin epithelium by intracutaneous transplantation and reproduced the stem cell niche and hair cycles. The bioengineered hair follicles also autonomously connected with nerves and the arrector pili muscle at the permanent region and exhibited piloerection ability. Our findings indicate that the bioengineered hair follicles could restore physiological hair functions and could be applicable to surgical treatments for alopecia. PMID:22645640

    Full Text Available Renal transplantation has profound improvements in mortality, morbidity, and overall quality of life compared to renal replacement therapy. This report aims to illustrate the use of ex-vivo partial nephrectomy in a patient with a renal angiomyolipoma prior to living donor transplantation. The surgical outcomes of the donor nephrectomy and recipient transplantation are reported with 2 years of follow-up. Both the donor and recipient are healthy and without any significant comorbidities. In conclusion, urologic techniques such as partial nephrectomy can be used to expand the living donor pool in carefully selected and well informed transplant recipients. Our experience demonstrated a safe and positive outcome for both the recipient and donor, and is consistent with other reported outcomes in the literature.

    Critical limb ischemia (CLI) with distal leg necrosis in lung transplant recipients (LTR) is associated with a high risk for systemic infection and sepsis. Optimal management of CLI has not been defined so far in LTR. In immunocompetent individuals with leg necrosis, surgical amputation would be indicated and standard care. We report on the outcome of four conservatively managed LTR with distal leg necrosis due to peripheral arterial disease (PAD) with medial calcification of the distal limb vessels. Time interval from lung transplantation to CLI ranged from four years (n = 1) to more than a decade (n = 3). In all cases a multimodal therapy with heparin, acetylsalicylic acid, iloprost and antibiotic therapy was performed, in addition to a trial of catheter-based revascularization. Surgical amputation of necrosis was not undertaken due to fear of wound healing difficulties under long-term immunosuppression and impaired tissue perfusion. Intensive wound care and selective debridement were performed. Two patients developed progressive gangrene followed by auto-amputation during a follow-up of 43 and 49 months with continued ambulation and two patients died of unrelated causes 9 and 12 months after diagnosis of CLI. In conclusion, we report a conservative treatment strategy for distal leg necrosis in LTR without surgical amputation and recommend this approach based on our experience.

    Metabolic syndrome is a risk factor for cardiovascular diseases. Higher risk of the metabolic syndrome and its components in patients after kidney transplantation is caused by immunosuppressive therapy. THE AIM OF OUR STUDY was to evaluate the prevalence of the metabolic syndrome and its components in kidney transplant recipients and to analyse their influence on allograft function and albuminuria. In the study we monitored 69 patients after cadaveric kidney transplantation. The prevalence of the meta-bolic syndrome was 61.3 % 3 years after kidney transplantation. The prevalence of new onset diabetes mellitus after transplantation was 27 % and that of abdominal obesity 59.7 % of patients. The age of kidney transplant recipients with the metabolic syndrome was higher than of these without it, but not statistically significant. The age of kidney transplant recipients with new onset diabetes mellitus after transplantation was significantly higher, 54.0 (35.0; 69.0) years, than in patients without it, 45.5 (27.0; 60.0) years, OR (95% IS) 1.116 (1.031; 1.207), p = 0.006.The number of components of the metabolic syndrome was negatively correlated with the graft function (rs -0,275, p = 0,031). In patients with impaired renal function with estimated glomerular filtration (using MDRD equation) metabolic syndrome and hypertriglyceridaemia was significantly higher. Chronic allograft dysfunction was predicted by donor age, delayed allograft function, rejection, low level of HDL-cholesterol, hypertriglyceridaemia and hyperuricaemia. Hyperuricaemia was the only significant predictor of allograft dysfunction independently of the presence of delayed allograft function, rejection episodes and donor age. The metabolic syndrome, elevation of apolipoprotein B and nonHDL-cholesterol and increased systolic blood pressure were associated with albuminuria. Higher levels of apolipoprotein B and total cholesterol were independent predictors of increased albumin-creatinine ratio. Obesity

    Solid organ transplant patients frequently develop posttransplant malignancies including breast cancer. They may desire breast reconstruction after mastectomy, which could potentially be complicated by their transplant status, immunosuppressive regimen, and previous operations. We review our experience with patients who have undergone solid organ transplant and subsequent breast reconstruction after mastectomy After institutional review board approval, we queried our prospective breast reconstruction and solid organ transplant databases for corresponding patients. Inclusion criteria comprised breast reconstruction after solid organ transplant. A chart review was conducted of identified patients. Seventeen patients were identified: 1 pulmonary transplant, 4 cardiac transplants, 2 liver transplants, 1 pancreas transplant, 2 combined kidney/pancreas transplants, and 7 kidney transplants. Indications for mastectomy included posttransplant malignancy and prophylaxis. Median time from transplant to completion of reconstruction was 186 months (range, 11-336 months). Median age at transplant was 34.5 years (range, 21-65 years) with the median age of the patients at reconstructive surgery 51.5 years (range, 34-71 years). Median body mass index was 25.3 (range, 21.3-46.5). No significant complications were noted after reconstructive surgery. All patients were on full immunosuppression at time of reconstruction. Breast reconstruction is a viable option for transplant patients after mastectomy and should not be refused based on their transplant status. Close coordination with the transplant team and careful preoperative planning is essential for optimal outcomes.

    Organ transplantation has evolved into the standard of care for patients with end-stage organ failure. Despite considering increasingly complex transplant recipients for organs recovered from donors with increasing comorbid conditions, 1-year patient survival following kidney transplantation is 97% in the United States, whereas liver transplant recipient 1-year survival is 90%. There were 16,485 kidney recipients in the United States in 2012, and 6256 patients who underwent liver transplantation. The intent of this review is to highlight the logistics required for transplantation as well as reviewing the current oversight of transplantation. Copyright © 2013 Elsevier Inc.

    There is increasing unmet need for solid organ donation. Alternative donor sources, such as donation after circulatory determination of death (DCDD), are needed. The objective of this study was to examine the impact of DCDD on trends in pediatric organ donation and transplantation. Data were obtained from the Organ Procurement and Transplantation Network for US organ recipients and donors from 2001 to 2010 stratified according to age, organ, and deceased donor type (DCDD or donation after neurologic determination of death). Additional data included transplant wait-list removals due to death. From 2001 to 2010, pediatric organ transplant recipients increased from 1170 to 1475. Organs from DCDD donors were transplanted into children infrequently but increased from 1 to 31. Pediatric donation after neurologic determination of death decreased by 13% whereas DCDD increased by 174% (50 to 137). Recipients of pediatric grafts decreased from 3042 to 2751. Adults receiving grafts from pediatric donors decreased from 2243 to 1780; children receiving pediatric grafts increased from 799 to 971. Transplant recipients receiving pediatric DCDD grafts were few but increased annually from 50 to 128 adults and 0 to 9 children. Pediatric candidates dying waiting for an organ decreased from 262 to 110. From 2001 to 2010, children received more solid organ transplants and fewer children died waiting. Organ recovery from pediatric and adult DCDD donors increased. The number of pediatric recipients of DCDD grafts remains small. Adults primarily receive the direct benefit from pediatric DCDD but other changes in organ allocation have directly benefited children.

    This paper discusses the development of methods for computer-aided jaw surgery. Computer-aided jaw surgery allows us to incorporate the high level of precision necessary for transferring virtual plans into the operating room. We also present a complete computer-aided surgery (CAS) system developed in close collaboration with surgeons. Surgery planning and simulation include construction of 3D surface models from Cone-beam CT (CBCT), dynamic cephalometry, semi-automatic mirroring, interactive cutting of bone and bony segment repositioning. A virtual setup can be used to manufacture positioning splints for intra-operative guidance. The system provides further intra-operative assistance with the help of a computer display showing jaw positions and 3D positioning guides updated in real-time during the surgical procedure. The CAS system aids in dealing with complex cases with benefits for the patient, with surgical practice, and for orthodontic finishing. Advanced software tools for diagnosis and treatment planning allow preparation of detailed operative plans, osteotomy repositioning, bone reconstructions, surgical resident training and assessing the difficulties of the surgical procedures prior to the surgery. CAS has the potential to make the elaboration of the surgical plan a more flexible process, increase the level of detail and accuracy of the plan, yield higher operative precision and control, and enhance documentation of cases.

There is little information regarding arterial elasticity in heart transplant recipients. This study aimed to characterize small (SAE and large (LAE artery elasticity in heart transplant recipients in comparison with an asymptomatic population free of overt cardiovascular disease. A second goal was to identify demographic and clinical factors associated with arterial elasticity in this unique population.Methods: Arterial pulse waveform was registered noninvasively at the radial artery in 71 heart transplant recipients between 2008 and 2010. SAEs and LAEs were derived from diastolic pulse contour analysis. Comparisons were made to a healthy cohort of 1,808 participants selected from our prevention clinic database. Multiple regression analyses were performed to evaluate associations between risk factors and SAE and LAE within the heart transplant recipients.Results: LAE and SAE were significantly lower in heart transplant recipients than in the normal cohort (P <0.01 and P < 0.0001, respectively. Female sex and history of ischemic cardiomyopathy were significantly associated with reduced LAE and SAE. Older age and the presence of moderate cardiac allograft vasculopathy were also significantly associated with reduced SAE. Transplant duration was associated with increased SAE.Conclusion: Heart transplants are associated with peripheral endothelial dysfunction and arterial stiffness, as demonstrated by a significant reduction in SAE and LAE when compared with a

    Liver transplantation is a life-saving therapy to correct liver failure, portal hypertension and hepatocellular carcinoma arising from hepatitis C infection. But despite the successful use of living donors and improvements in immunosuppression and antiviral therapy, organ demand continues to outstrip supply and recurrent hepatitis C with accelerated progression to cirrhosis of the graft is a frequent cause of graft loss and the need for retransplantation. Appropriate selection of candidates and timing of transplantation, coupled with better pre- and post-transplant antiviral therapy, are needed to improve outcomes.

    Heart transplantation after lung cancer surgery can be questionable because of the high risk of cancer recurrence. We report the results of two patients. The first underwent right lobectomy in 2008 for pT1N0 adenocarcinoma, heart-transplantation in 2010, and surgery for synchronous adenocarcinoma and squamous-cell carcinoma in 2012. The second underwent left segmentectomy for pT1aN0 adenosquamous carcinoma and transplantation in 1995 and then surgery for pT1aN1 adenocarcinoma in 2013. Posttransplantation lung cancer histologic analysis results were different in both cases, demonstrating the absence of metastatic recurrence. Thus, early stage lung cancer might not be a contraindication to heart transplantation, nor are long delays be necessary before registering on a waiting list.

    The present article reports the characteristics and outcome of heart transplantation in Spain since it was first performed in May 1984. We provide a descriptive analysis of the characteristics of the recipients, the donors, the surgical procedure, and results of the heart transplantations performed in Spain until 31 December 2013. During 2013, a total of 248 transplantation procedures were carried out, bringing the time series to a total of 7023 transplantations. The temporal analysis confirms a significant deterioration in the clinical profile of the recipients (higher percentage of older patients, severe renal failure, insulin-dependent diabetes mellitus, previous heart surgery, mechanical ventilation), of the donors (higher proportion of older donors and greater weight mismatch), and of the procedure (higher percentage of emergency transplantations which, in 2013, reached 49%, and with ischemia times > 240min). There was a marked increase in the use of circulatory assist devices prior to transplantation which, in 2013, were employed in 25.2% of all the patients. The survivals at 1, 5, 10, and 15 years were 76%, 65%, 52%, and 37%, respectively, and have remained stable since 1995. Heart transplantation activity in Spain remains stable in recent years, with around 250 procedures a year. Despite the clear deterioration in the clinical characteristics of the donors and recipients, and lengthening of the operative times, the results in terms of mortality continue to be comparable to those reported in our neighboring countries, and a growing use of circulatory assist devices prior to transplantation is confirmed.

    Simultaneous pancreas-kidney (SPK) transplantation is the primary surgical treatment for type I diabetes mellitus with end-stage renal disease. However, this transplant surgery has a high-risk of surgical complications, including duodenal anastomotic leakage, which may lead to pancreas transplantation failure if the leakage worsens. This case report describes a patient who suffered from duodenal anastomotic leakage after SPK transplantation. The digestive enzymes eroded the wound and skin around the wound, resulting in periwound moisture-associated dermatitis. During the period of nursing care, the wound-care intervention was determined by interdisciplinary cooperation. In our case report, the periwound moisture-associated dermatitis healed completely under inter-hospital care. In clinical nursing practice, periwound moisture-associated dermatitis should be cared in combination with macerated wounds. We suggest the following: (1) control the moisture source; (2) use advanced dressings as the primary dressing with sterile gauze as a secondary dressing and silver antimicrobial dressings for infected wounds; (3) consider using negative pressure wound therapy for complicated chronic wounds; and (4) use a pH-neutral skin cleanser with non-woven gauze to clean the periwound skin and keep the skin clean and dry. Finally, we suggest isolating and protecting the skin with No Sting Barrier Film and a hydrocolloid dressing. We hope this nursing care experiences serves as a reference for the nursing care of periwound moisture-associated dermatitis resulting from duodenal anastomotic leakage during / after SPK transplantation.

    Full Text Available Liver transplantation is the only available treatment for some patients with end-stage liver disease. Despite reduction in mortality rates due to advances related to surgical techniques, intensive medical management and immunosuppressive therapy, invasive fungal infections remain a serious complication in orthotopic liver transplantation. We report the case of an 18-year-old male diagnosed with autoimmune cirrhosis in 2009 who was assessed and listed for liver transplantation for massive variceal hemorrhage. One year after listing a successful orthotopic liver transplantation was performed. Uneventful early recovery was achieved; however, he developed pulmonary and neurological Aspergillus infection 23 and 40 days after surgery, respectively. Antibiotic therapy with voriconazole and amphotericin was started early, with no major response. Neuroimaging revealed multiple right frontal and right parietal lesions with perilesional edema; surgical management of the brain abscesses was performed. A biopsy with periodic acid-Schiff and Gomori stains revealed areas with mycotic microorganisms morphologically consistent with Aspergillus, later confirmed by culture. The patient developed necrotizing encephalitis secondary to aspergillosis and died. Necrotizing encephalitis as a clinical presentation of Aspergillus infection in an orthotopic liver transplant is not common, and even with adequate management, early diagnosis and prompt antifungal treatment, mortality rates remain high.

    The shortage of cadaver kidneys relative to increasing demand for transplantation has lead to a remarkable rise in transplantation from living donors. Based upon data reported to UNOS, the number of living donor kidneys transplanted in 2000 (5,106) nearly equaled the number of cadaver kidneys from preferred donors aged 6-50. HLA-mismatched siblings, offspring, spouses and other genetically unrelated donors accounted for nearly 80% of increased living donor transplantation during 1994-2000. Despite the increased use of poorly HLA-matched living donor kidneys, the actuarial 10-year graft survival rates for transplants between 1988-2000 were clustered between 53-57% for HLA-mismatched living donor grafts, except for offspring-to-parent transplants (49%) when the recipients were generally older. The 10-year survival rate for 96,053 cadaver grafts was 38% during the same period. The 5-year graft survival rates for more recent (1996-2000) cadaver donor transplants were 66%, 62% and 56% for recipients of first, second and multiple grafts, respectively (p < 0.001). The comparable results among recipients of living donor kidneys were 67%, 66% and 59% (p = ns). The 5-year graft survival rates for HLA-matched first grafts were 7% higher than those for HLA-mismatched transplants when the kidney was from a living or cadaver donor. HLA-identical sibling transplants provided the best long-term graft survival (85% at 5 years and a 32 year half-life). Even with improved crossmatch tests and stronger immunosuppression, sensitization was associated with 8% lower graft survival at 5 years and with a higher rate of late graft loss among first cadaver kidney recipients. Sensitization also was associated with an increase in delayed graft function from 22% of unsensitized first transplant recipients to as much as 36% among multiply retransplanted patients. Recipient race was a key factor in long-term graft survival of both living and cadaver donor kidneys. The rate of late graft loss was

    Older kidney transplant recipients are susceptible to cognitive impairment, frailty, comorbidities, immunosuppression-related complications, and chronic graft failure, however, there has been limited focus on their concerns and expectations related to transplantation. This study aims to describe the perspectives of older kidney transplant recipients about their experience of kidney transplantation, self-management, and treatment goals to inform strategies and interventions that address their specific needs. Face-to-face semistructured interviews were conducted with 30 kidney transplant recipients aged 65-80 years from five renal units in Australia. Transcripts were analyzed thematically. Six themes were identified: restoring vitality of youth (with subthemes of revived mindset for resilience, embracing enjoyment in life, drive for self-actualization); persisting through prolonged recovery (yielding to aging, accepting functional limitations, pushing the limit, enduring treatment responsibilities); imposing sicknesses (combatting devastating comorbidities, painful restrictions, emerging disillusionment, anxieties about accumulating side effects, consuming treatment burden); prioritizing graft survival (privileged with a miracle, negotiating risks for longevity, enacting a moral duty, preserving the last opportunity); confronting health deterioration (vulnerability and helplessness, narrowing focus to immediate concerns, uncertainty of survival); and value of existence (purpose through autonomy, refusing the burden of futile treatment, staying alive by all means). Older kidney transplant recipients felt able to enjoy life and strived to live at their newly re-established potential and capability, which motivated them to protect their graft. However, some felt constrained by slow recuperation and overwhelmed by unexpected comorbidities, medication-related side effects, and health decline. Our findings suggest the need to prepare and support older recipients for self

    Except for legends and claims of miracles, most histories of transplantation cover only the last 60 years because there were no earlier successes. However, the story of even this era has been documented in such rich detail that a full account would fill several volumes. Thus, this brief summary must be limited to highly selected “landmarks.” Some landmarks had an immediate impact, but the importance of others went unrecognized for decades. Some findings that deserved landmark status were overlooked or forgotten, whereas others of no biological significance had major impact. Placing these events in perspective is challenging. Several of transplantation’s pioneers are still alive, and most of the others are within living memory. Virtually all of them have produced their own accounts. For the most part, they agree on what the “landmarks” are, but their differences in emphasis and perspective make an interesting story. PMID:23545575

    On 17 February 1968, Bombay surgeon Prafulla Kumar Sen transplanted a human heart, becoming the fourth surgeon in the world to attempt the feat. Even though the patient survived just three hours, the feat won Sen worldwide acclaim. The ability of Sen's team to join the ranks of the world's surgical pioneers raises interesting questions. How was Sen able to transplant so quickly? He had to train a team of collaborators, import or reverse engineer technologies and techniques that had been developed largely in the United States, and begin conversations with Indian political authorities about the contested concept of brain death. The effort that this required raises questions of why. Sen, who worked at a city hospital in Bombay that could not provide basic care for all its citizens, sought a technology that epitomized high-risk high-cost, health care. To accomplish his feat, Sen navigated Cold War tensions and opportunities, situating his interests into those of his hospital, municipal authorities, Indian nationalism, Soviet and American authorities, the Rockefeller Foundation, and others. The many contexts and interests that made Sen's work possible created opportunities for many different judgments about the success or failure of medical innovation. © The Author(s) 2018.

    2015-04-01

    The scarcity of liver grafts requires to optimize the results of transplantation. Extensions and alternatives of liver transplantation have to be regularly evaluated. Acute-on-chronic liver failure and severe alcoholic hepatitis may represent potential extensions of transplant indications. In these diseases, selected patients could obtain a significant benefit from liver transplantation, whereas long-term outcomes and global impact on waiting lists remain to be evaluated prospectively. Alternatives to transplantation may be represented by recent progress in the management of hepatitis C and the treatment of hepatocellular carcinoma. In hepatitis C, new drug combinations may improve the disease control, reducing the progression to cirrhosis and also the risk of post-transplant reinfection allowing to anticipate a future decrease in the indications for transplantation and retransplantation in these patients. In hepatocellular carcinoma, thanks to improvements in operative techniques and better identification of prognostic factors of cancer recurrency, surgical resection or radiofrequency destruction could appear now as true alternatives to transplant in highly selected patients. Before implementation of these potential changes into decisional algorithms for listing and organ allocation, their consequences, either for patient's individual benefit or for global transplant outcomes, should be closely evaluated using objective long-term end points and taking into account the ethical recommendations for organ transplantation.

    2014-03-01

    Liver transplantation is the definitive treatment for end-stage liver diseases. The first successful liver transplant was performed in the United States by Thomas Starzl in 1967. The first successful solid organ transplant in Turkey was a living-related kidney transplant performed by Dr. Haberal in 1975. After much effort by Dr. Haberal, the Turkish parliament enacted a law about organ transplantation in 1979. After clinical and experimental studies, the first liver transplant in Turkey was performed by Dr. Haberal in 1988. The first successful partial living-donor liver transplant in children in Turkey was performed by the same team on March 15, 1990. On April 24, 1990, the first living-donor liver transplant was performed on a child in Turkey using a left lateral segment by Dr. Haberal and coworkers. On May 16, 1992, Dr. Haberal performed a simultaneous living-donor liver and kidney transplantation to an adult from the same donor. There currently are 30 liver transplantation centers in Turkey. According to data from the Ministry of Health, there presently are 2065 patients in Turkey who are waiting for a liver transplantation. From January 2002 to June 2013, there were 6091 liver transplants performed in Turkey (4020 living-donor [66% ] and 2071 deceased donor liver transplants [34% ]). From January 2011 to June 2013, there were 2514 patients who had liver transplants in Turkey, and 437 patients (17%) died. The number of liver transplants per year in Turkey reached 1000 transplants in 2012 and more than 1150 transplants in 2013 (15.1/million/y). Therefore, Turkey has one of the highest volumes of liver transplantation per population worldwide, with 90% survival within 1 year after transplantation.

    BK virus (BKV) is a subtype of papovaviridae. The latent and asymptomatic infection of BKV is common among healthy people. The incidence of BKV re-activation in renal transplant recipients ranges 10%-68%. About 1%-7% of renal transplant recipients will suffer from BKV-associated nephropathy (BKVAN), and half of them will experience graft failure. This paper summarizes the re-activation mechanism of BKV as well as the risk factors, pathology, diagnosis, and treatment of BKVAN.

    Orthotopic liver transplantation is commonly performed at many institutions around the world. The care of these critically ill patients has heavily relied upon cross-sectional imaging, specifically CT. CT is of enormous benefit in the postoperative management of the various complications which is common in this group of patients. This article reviews the role of CT and its respective strengths and weaknesses, in the adult liver transplant recipient. (orig.) [de

    A month-old baby girl with blood type O positive received a donor heart organ from a donor with blood type B. This was the first institutional ABO-incompatible heart transplant. Infants listed for transplantation may be considered for an ABO-incompatible heart transplant based on their antibody levels and age. The United Network of Organ Sharing (UNOS) protocol is infants under 24 months with titers less than or equal to 1:4.(1) This recipient's anti-A and anti-B antibodies were monitored with titer assays to determine their levels; antibody levels less than 1:4 are acceptable pre-transplant in order to proceed with donor and transplant arrangements.1 Immediately prior to initiating cardiopulmonary bypass (CPB), a complete whole body exchange transfusion of at least two-times the patient's circulating blood volume was performed with packed red blood cells (pRBC), fresh frozen plasma (FFP) and 25% albumin. Titer assays were sent two minutes after initiation of full CPB and then hourly until the cross-clamp was removed. Institutionally, reperfusion of the donor heart is not restored until the antibody level from the titer assay is known and reported as less than 1:4; failing to achieve an immulogically tolerant recipient will provide conditions for hyperacute rejection. The blood collected during the transfusion exchange was immediately processed through a cell saver so the pRBC's could be re-infused to the patient during CPB, as necessary. The remainder of the transplant was performed in the same fashion as an ABO-compatible heart transplant. The patient has shown no signs of rejection following transplantation. © The Author(s) 2014.

    Organs for transplantation are a scarce resource. Paying to increase the supply of organs is illegal in much of the world. We review efforts to increase transplantation by increasing the supply of available organs from living and deceased donors. Progress has been made in increasing the availability of living donor kidneys through kidney exchange. Recent legislation in Israel aims at encouraging deceased donation by awarding priority for receiving organs to registered donors. We also explore ...

    Full Text Available Complications of the biliary tract like bile leaks, strictures are an important cause of morbidity and mortality after liver transplantation. The frequency of such complications ranges from 5 to 25%. In most cases, biliary complications can be treated by endoscopy and/or methods of interventional radiology. This article is about the clinical case of liver transplantation with duct-to-duct biliary reconstruction, complicated by bile leaks, biliary tract stricture. Surgical correction of complications was ineffective. We used miniinvasive methods and got po- sitive clinical outcome after radiology intervention for prosthetics of the common bile duct.

    Full Text Available Chronic kidney disease has direct implications in nutritional status, causing anorexia and muscular catabolism. These situations are frequent in kidney renal replacement therapy in which nutritional disorders and inflammatory mechanisms associated with therapy often lead to the development of protein-energy wasting. Nutrition therapy has shown an adequate therapeutic strategy to prevent and treat metabolic alterations, reducing surgical and nutritional complication risks in kidney transplantation patients. The current case reports nutritional intervention on a continuous ambulatory peritoneal dialysis patient who was subsequently prescribed to automatic peritoneal dialysis and, finally, kidney transplant from a living donor.

    2010-10-01

    Joseph Lister (1827-1912), renowned British surgeon-scientist, introduced to the world the use and appreciation of the antiseptic method for the prevention of wound sepsis. Armed with the ideas of Louis Pasteur (1822-1895) regarding the role of microorganisms in infections or the so-called germ theory of disease, he advanced the surgical field by using antiseptics, such as carbolic acid, in the treatment of contaminated wounds. These developments constituted a real surgical revolution. No breakthrough before Lister's, except perhaps the discovery of anesthesia, had contributed to such an incredible advancement in relationship to the surgical arena. After 1867, the year in which Lister published his remarkable paper in Lancet, it was possible to appropriately treat or prevent wound infections with the use of antiseptics at the site of the operated wound. Lister's method was complicated but produced its desired effect--to diminish wound morbidity and patient mortality. His contribution was secured for future generations and a surgical revolution had begun!

    The surgical educational environment is potentially stressful and this can negatively affect students' learning. The aim of this study was to investigate whether veterinary students' level of anxiety is higher in a surgical course than in a non-surgical course and if pre-surgical training...... in a Surgical Skills Lab (SSL) has an anxiety reducing effect. Investigations were carried out as a comparative study and a parallel group study. Potential participants were fourth-year veterinary students who attended a surgical course (Basic Surgical Skills) and a non-surgical course (Clinical Examination......

    Full Text Available Renal transplantation is burdened by high cardiovascular risk because of increased prevalence of traditional and disease-specific cardiovascular risk factors and, consequently, patients are affected by greater morbidity and mortality. In renal transplanted patients, healthy lifestyle and physical activity are recommended to improve overall morbidity and cardiovascular outcomes. According to METs (Metabolic Equivalent Task; i.e. the amount of energy consumed while sitting at rest, physical activities are classified as sedentary (<3.0 METs, of moderate-(3.0 to 5.9 METs or vigorous-intensity (≥6.0 METs. Guidelines suggest for patients with chronic kidney disease an amount of physical activity of at least 30 minutes of moderate-intensity activity five times per week (min 450 MET-minutes/week. Data on physical activity in renal transplanted patients, however, are limited and have been mainly obtained by mean of non-objective methods. Available data suggest that physical activity is low either at the start or during renal transplantation and this may be associated with poor patient and graft outcomes. Therefore, in renal transplanted patients more data on physical activity obtained with objective, accelerometer-based methods are needed. In the meanwhile, physical activity have to be considered as an essential part of the medical care for renal transplanted recipients.

    Renal transplantation is the most effective mode of renal replacement therapy for correction of renal failure. Renal donors can either be: a. a deceased person - the kidneys being removed when brain death or absence of cerebral cortical function / perfusion is confirmed - the cadaveric kidney is packed in ice and nutrient solution and transplanted within 24 hours of removal ('cold ischemia') ob. a living donor - the donor may or may not be related to the recipient. Due to the limited length of the renal vessels and ureter of the donor kidney, it is implanted close to the bladder of the recipient. The donor vessels are anastomosed to the iliac artery and vein of the recipient. Transplant variants: a. 2 kidneys maybe transplanted because: - an old donor with less kidney reserve from atrophy due to age or disease (e.g. hypertension) - an infant donor when both kidneys are removed en bloc, b. Donor kidneys with more than 1 artery, vein or ureter. c. Donor horse shoe kidney d. Combined renal and pancreas transplant for type I diabetics -a short segment of duodenum transplanted with the pancreas maybe implanted into the bladder.

    1999-01-01

    There are an increasing amount of data which are compelling us to consider the issue of age in dealing with decisions regarding both renal transplant recipients and donors. These geriatric issues in transplantation can be summarized as follows: (1) The explosion of a geriatric population of patients with ESRD, in association with data showing a survival advantage of transplantation over wait-listed dialysis patients, demands an increase in expertise in transplantating patients over 60 years old. (2) The critical shortage in cadaveric organ supply is creating a variety of solutions including expanding the donor pool with older kidneys in which long term survival may be shorter than in kidneys from younger donors. (3) The donor shortage, in association with data demonstrating improved survival of living related and unrelated donor transplants, is generating an increased number of older (> 60 years old) individuals who want to donate to a relative, spouse or friend. Future efforts should be directed toward continued research designed to evaluate the efficacy and safety of these trends. We also need to provide improved training in geriatrics for nephrologists so that we and transplant surgeons can deliver better medical care to an aging population of patients with ESRD.

  10. Inflammatory Response in Islet Transplantation

    2014-01-01

    Full Text Available Islet cell transplantation is a promising beta cell replacement therapy for patients with brittle type 1 diabetes as well as refractory chronic pancreatitis. Despite the vast advancements made in this field, challenges still remain in achieving high frequency and long-term successful transplant outcomes. Here we review recent advances in understanding the role of inflammation in islet transplantation and development of strategies to prevent damage to islets from inflammation. The inflammatory response associated with islets has been recognized as the primary cause of early damage to islets and graft loss after transplantation. Details on cell signaling pathways in islets triggered by cytokines and harmful inflammatory events during pancreas procurement, pancreas preservation, islet isolation, and islet infusion are presented. Robust control of pre- and peritransplant islet inflammation could improve posttransplant islet survival and in turn enhance the benefits of islet cell transplantation for patients who are insulin dependent. We discuss several potent anti-inflammatory strategies that show promise for improving islet engraftment. Further understanding of molecular mechanisms involved in the inflammatory response will provide the basis for developing potent therapeutic strategies for enhancing the quality and success of islet transplantation.

     No consensus treatment option for focal osteochondral defects of the proximal lunate exist in the literature. Surgical management has thus far been limited to salvage procedures such as proximal row carpectomy and partial arthrodesis.  We report our experience using the osteochondral autograft transplantation surgery (OATS) procedure in two young, active patients with focal osteochondral defects of the proximal lunate. At mean follow-up of 6 years, sustained improvements in pain, motion, and function were observed. Both patients reported high levels of satisfaction and neither experienced any complications.  To our knowledge, this is the first report describing the use of OATS to treat proximal lunate defects.  OATS is a valuable surgical option for treating focal chondral defects of the proximal lunate, with positive outcomes at greater than 5 years postoperatively. This may be an especially useful technique for younger, active patients, and those wishing to maintain maximum functionality.

  12. SERS-Based Prognosis of Kidney Transplant Outcome

    Science.gov (United States)

    Chi, Jingmao

    Kidney transplant is the predominant procedure of all organ transplants around the world. The number of patients on the waiting list for a kidney is growing rapidly, yet the number of donations does not keep up with the fast-growing need. This thesis focuses on the surface-enhanced Raman scattering (SERS) analysis of urine samples for prognosis of kidney transplant outcome, which can potentially let patients have a more timely treatment as well as expand the organ pool for transplant. We have observed unique SERS spectral features from urine samples of kidney transplant recipients that have strong associations with the kidney acute rejection (AR) based on the analysis of urine one day after the transplant. Our ability to provide an early prognosis of transplant outcome is a significant advance over the current gold standard of clinical diagnosis, which occurs weeks or months after the surgical procedure. The SERS analysis has also been applied to urine samples from deceased kidney donors. Excellent classification ability was achieved when the enhanced PCA-LDA analysis was used to classify and identify urine samples from different cases. The sensitivity of the acute tubular necrosis (ATN) class is more than 90%, which can indicate the usable kidneys in the high failure risk category. This analysis can help clinicians identify usable kidneys which would be discarded using conventional clinic methods as high failure risk. To investigate the biomarkers that cause the unique SERS features, an HPLC-SERS-MS approach was established. The high-performance liquid chromatography (HPLC) was used to separate the urinary components to reduce the sample complexity. The mass spectrometry (MS) was used to determine the formulas and the structures of the biomarkers. The presence of 1-methyl-2-pyrrolidone (NMP) and adenine in urine samples were confirmed by both MS and SERS analysis. Succinylmonocholine, a metabolite of suxamethonium, has a potential to be the biomarker that causes

    Vaccination of pediatric liver transplant candidates and recipients represents an opportunity to decrease infectious complications following transplant. Although vaccine recommendations exist, studies have shown that many transplant candidates and recipients are under-immunized. The goals of this study were to assess among pediatric transplant hepatologists: (i) current immunization practices before and after transplantation, (ii) involvement of an ID physician in the transplant evaluation, and (iii) perceptions about vaccine safety and barriers to immunization. An 80-item e-mail survey of pediatric transplant hepatologists at centers in the United States and Canada participating in the SPLIT consortium was conducted from December 2014 to March 2015. The overall response rate was 80% (73/91), representing 97% (32/33) of SPLIT centers. Fifty percent of programs routinely involved an ID physician in the transplant evaluation. Administration of palivizumab was routinely considered by 48% of hepatologists pre-transplant and by 41% post-transplant. Live vaccines were recommended by 26% of hepatologists after transplant. About 10% of hepatologists reported concern that live vaccines after transplant could induce rejection. There is wide variation in immunization practices among transplant hepatologists. Specific evidence-based protocols are needed to guide immunization practices in transplant candidates and recipients. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  14. Hepatocellular Carcinoma: Current Management and Future Development—Improved Outcomes with Surgical Resection

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Currently, surgical resection is the treatment strategy offering the best long-term outcomes in patients with hepatocellular carcinoma (HCC. Especially for advanced HCC, surgical resection is the only strategy that is potentially curative, and the indications for surgical resection have expanded concomitantly with the technical advances in hepatectomy. A major problem is the high recurrence rate even after curative resection, especially in the remnant liver. Although repeat hepatectomy may prolong survival, the suitability may be limited due to multiple tumor recurrence or background liver cirrhosis. Multimodality approaches combining other local ablation or systemic therapy may help improve the prognosis. On the other hand, minimally invasive, or laparoscopic, hepatectomy has become popular over the last decade. Although the short-term safety and feasibility has been established, the long-term outcomes have not yet been adequately evaluated. Liver transplantation for HCC is also a possible option. Given the current situation of donor shortage, however, other local treatments should be considered as the first choice as long as liver function is maintained. Non-transplant treatment as a bridge to transplantation also helps in decreasing the risk of tumor progression or death during the waiting period. The optimal timing for transplantation after HCC recurrence remains to be investigated.

    The surgical treatment of alopecia is essentially based on minigraft and micrograft techniques in which grafts are inserted into a slit or punch recipient site. To facilitate the transplantation of large numbers of these small grafts, the Calvitron automated hair transplant system has been developed. We report a case of Norwood type V alopecia who received three sessions of hair transplantation (400-500 grafts per session) over 18 months with satisfactory results. During surgery, with one technician operating the machine, one surgeon and an assistant took 3.5 to 4 hours per session to accomplish the whole procedure from harvesting the grafts to implantation and closure of the donor scalp wound. This new automated minigraft and micrograft transplant technique is significantly timesaving for large numbers of grafts per session without altering the aesthetic results. It offers a good choice for hair replacement surgery to save manpower and cost. The use of the Calvitron automated hair transplant system proved to be a practical and effective approach to hair transplantation in this case.

    A subset of children who receive a liver and/or kidney transplant develop de novo inflammatory bowel disease-like chronic intestinal inflammation, not explained by infection or medications, following transplant. We have conducted a single-center, retrospective case series describing the unique clinical and histologic features of this IBD-like chronic intestinal inflammation following solid organ transplant. At our center, nine of 327 kidney or liver recipients developed de novo IBD following transplant (six liver, two kidney, one liver-kidney). Most children presented with prolonged hematochezia and diarrhea and were treated with aminosalicylates. At time of diagnosis, five were not currently using mycophenolate mofetil for transplant immunosuppression. Histologic and endoscopic findings at IBD diagnosis included inflammation, ulcerations, granulomas, and chronic colitis. Since diagnosis, no patients have required surgical intervention, or escalation to biologic therapy, nor developed stricturing or perianal disease. In this case series, de novo post-transplant IBD developed in 4% of pediatric liver and/or kidney recipients; however, it often does not fit the classic patterns of Crohn's disease or ulcerative colitis. © 2016 John Wiley & Sons A/S.

    To minimize cold ischemia time, transplantations with kidneys from deceased donors are frequently performed during the night. However, sleep deprivation of those who perform the transplantation may have adverse effects on cognitive and psychomotor performance and may cause reduced cognitive flexibility. We hypothesize that renal transplantations performed during the night are associated with an increased incidence of pure technical graft failure. A retrospective analysis of data of the Dutch Organ Transplant Registry concerning all transplants from deceased donors between 2000 and 2013 was performed. Nighttime surgery was defined as the start of the procedure between 8 p.m. and 8 a.m. The primary outcome measure was technical graft failure, defined as graft loss within 10 days after surgery without signs of (hyper)acute rejection. Of 4.519 renal transplantations in adult recipients, 1.480 were performed during the night. The incidence of pure technical graft failure was 1.0 % for procedures started during the night versus 2.6 % for daytime surgery (p = .001). In a multivariable model, correcting for relevant donor, recipient and graft factors, daytime surgery was an independent predictor of pure technical graft failure (p technical graft failures. Further research is required to explore factors that may positively influence the performance of the surgical team during the night.

    The surgically-demanding mouse orthotopic liver transplant model was first described in 1991. It has proved a powerful research tool for investigation of liver biology, tissue injury, the regulation of alloimmunity and tolerance induction and the pathogenesis of specific liver diseases. Liver transplantation in mice has unique advantages over transplantation of the liver in larger species, such as the rat or pig, since the mouse genome is well-characterized and there is much greater availability of both genetically-modified animals and research reagents. Liver transplant experiments using various transgenic or gene knockout mice has provided valuable mechanistic insights into the immuno- and pathobiology of the liver and the regulation of graft rejection and tolerance over the past 25 years. The molecular pathways identified in regulation of tissue injury and promotion of liver transplant tolerance provide new potential targets for therapeutic intervention to control adverse inflammatory responses/ immune-mediated events in the hepatic environment and systemically. Conclusion: Orthotopic liver transplantation in the mouse is a valuable model for gaining improved insights into liver biology, immunopathology and allograft tolerance that may result in therapeutic innovation in liver and other diseases.

    Performing a pretransplantation splenectomy in patients with myelofibrosis (MF) is a matter of debate, as while the procedure improves hematological recovery, it may lead to severe morbidities. We retrospectively analyzed data from 85 consecutive patients who underwent transplantation in our center for MF, including 39 patients who underwent splenectomy before their transplantation. A majority of them had primary MF (78%), were considered high-risk patients (84% dynamic international prognostic scoring system intermediate-2 or higher), and had received transplants from HLA-matched sibling donors (56%) after a reduced-intensity conditioning regimen (82%). One-half of all splenectomized patients presented surgical or postsurgical morbidities, most frequently thrombosis and hemorrhage. After adjustment using Cox models, pretransplantation splenectomy was not associated with nonrelapse mortality or post-transplantation relapse but with an improved overall survival (OS) and event-free survival (EFS). We conclude that some patients with huge splenomegaly may undergo pretransplantation splenectomy without a deleterious impact on post-transplantation outcomes. OS and EFS improvement should in confirmed in controlled study. Copyright © 2017 The American Society for Blood and Marrow Transplantation. Published by Elsevier Inc. All rights reserved.

    In their book Spare Parts, published in 1992, Fox and Swazey criticized various aspects of organ transplantation, including the routinization of the procedure, ignorance regarding its inherent uncertainties, and the ethos of transplant professionals. Using this work as a frame of reference, we analyzed articles on organ transplantation published in internal medicine and transplantation journals between 1995 and 2008 to see whether Fox and Swazey's critiques of organ transplantation were still relevant. Using the PubMed database, we retrieved 1,120 articles from the top ten internal medicine journals and 4,644 articles from the two main transplantation journals (Transplantation and American Journal of Transplantation). Out of the internal medicine journal articles, we analyzed those in which organ transplantation was the main topic (349 articles). A total of 349 articles were randomly selected from the transplantation journals for content analysis. In our sample, organ transplantation was described in positive terms and was presented as a routine treatment. Few articles addressed ethical issues, patients' experiences and uncertainties related to organ transplantation. The internal medicine journals reported on more ethical issues than the transplantation journals. The most important ethical issues discussed were related to the justice principle: organ allocation, differential access to transplantation, and the organ shortage. Our study provides insight into representations of organ transplantation in the transplant and general medical communities, as reflected in medical journals. The various portrayals of organ transplantation in our sample of articles suggest that Fox and Swazey's critiques of the procedure are still relevant.

    Enormous progress has been made in paediatric heart transplantation since the first unsuccessful effort by Kantrowitz in 1967. Early reports of children undergoing heart transplantation showed alarmingly high perioperative mortality rates of 25-60%, with the diagnosis of congenital heart disease (CHD) representing a particularly high-risk subset compared with cardiomyopathy. Many of these early failures were related to poor patient selection, suboptimal immunosuppression and technical problems. We learned a great deal from these earlier difficulties. Presently, with more refined techniques, better-defined patient selection criteria, excellent graft rejection monitoring and optimal immunosuppression, the ISHLT 2011 registry reported a 10-year survival rate of 60% for patients transplanted for end-stage CHD and >70% for those transplanted for cardiomyopathy. The technical dilemmas in complex CHD were overcome by surgical ingenuity and creativity, innovative solutions and careful surgical planning, adapting the complex recipient anatomy to the normal donor anatomy. The miniaturized Berlin Heart pulsatile ventricular assist devices in children as a bridge to transplantation have revolutionized treatment and become a significant contribution in heart-failure therapy. The intramyocardial electrogram and echocardiographic strain rate imaging have been employed as non-invasive techniques of rejection monitoring. Immunosuppressive drugs have a major impact on the development and progression of cardiac allograft vasculopathy, the main cause of cardiac allograft loss and a leading cause of mortality after the first year post-transplantation. The questions of whether a transplanted heart in a newborn grows to adult size along with the child and whether the dimensional cardiac growth allows adequate function over time have been largely answered in our previous investigations. As more transplanted children reach adulthood, concerns about their life expectancy when they have

At time of admission, under maximal sympathomimetic therapy, the cardiac index (CI) was 1.81 +/- 0.26 l/min per m2, the pulmonary capillary wedge pressure (PCWP 31 +/- 7 mmHg), systemic vascular resistances (SVR) 2053 +/- 469 dynes s cm-5. In 25, diuresis was less than 25 ml/h. Five were anuric. Prior to any final decision, a new inotropic agent, enoximone, was infused in addition to previous treatment as a 10 min bolus iv 1.5-2 mg/kg every 8 h. In 3, the situation further deteriorated, leading to a Jarvik 7-70 implantation within 12 h. In 29 however, within 3 h, the Cl increased to 2.69 +/- 0.56 as SVR dropped to 1410 +/- 453 and PCWP to 18 +/- 7. Diuresis increased to more than 100 ml/h in all. This permitted an indepth evaluation of the transplant candidates leading to contraindications to transplantation in 16. Nine patients could be weaned off iv enoximone. Four of these are still living (NYHA class III) with a follow up of 6-17 months. In 11, transplantation was performed within 2 days. Four died within a month, 2 with multiple organ failure. One patient died after 5 months. Six are back to normal life, NYHA class I (follow up 10 months-2.5 years). This protocol suggests that in patients with extreme heart failure, immediate survival may be increased by iv enoximone therapy, permitting a better selection of the recipients, more efficient pre-transplantation intensive care and consequently a decrease in the indications for a temporary mechanical bridge to a staged transplantation.

    Chronic pancreatitis is an inflammatory disease that may require surgical intervention. In some patients a total pancreatectomy is necessary. Such patients develop diabetes, which in some cases may be difficult to control. When standard insulin treatment is unsuccessful and the patient has frequent blood glucose swings with life-threatening hiper- and hypoglycemic episodes, a pancreas transplant should be considered.

    2000-01-01

    Full Text Available The incidence of post-transplantation lymphoproliferative disorder (PTLD in the adult renal transplant population ranges from 0.7% to 4%. The majority of cases involve a single site and arise, on average, seven months after transplantation. Histopathology usually reveals B-cell proliferative disease and has been standardized into its own classification. Treatment modalities consist of decreased immunosuppression, eradication of Epstein-Barr virus, surgical resection, systemic chemotherapy and monoclonal antibody therapy; however, mortality remains high, typically with a short survival time. In patients who have undergone renal transplantation, approximately 10% of those with PTLDs present with gastrointestinal symptomatology and disease. Reported sites include the stomach, and small and large bowel. Very few cases of Helicobacter pylori or mucosal-associated lymphoid tissue have been described in association with PTLD. In the era of cyclosporine immunosuppression, the incidence of PTLD affecting the gastrointestinal tract may be increasing in comparison with the incidence seen with the use of older immunosuppression regimens. A case of antral PTLD and H pylori infection occurring three months after renal transplantation is presented, and the natural history and management of gastric PTLD are reviewed.

    This study describes the surgical technique and outcomes of live donor renal allografts with multiple arteries in which the lower polar artery was anastomosed to the inferior epigastric artery after declamping. Between 1988 and 2004, 477 consecutive live donor renal transplants were performed, including 429 with single and 48 with multiple arteries. Anastomosis of the lower polar artery to the inferior epigastric artery was used for 15 grafts with multiple arteries. Successful revascularization of all areas of the transplanted graft was confirmed by Doppler ultrasonography in most patients and radionuclide renal scanning +/- MRA in some patients. In live donor renal transplantation with multiple arteries, the anastomosis of the lower polar artery to the inferior epigastric artery after declamping avoids prolongation of the ischemia time that occurs with other surgical and microsurgical techniques of intracorporeal and ex vivo surgeries.

    2015-01-01

    Full Text Available We report a case of renal transplantation using a horseshoe kidney from a living, genetically unrelated donor. The recipient was a 60-year-old man with diabetic nephropathy, and the donor was the 63-year-old wife of the recipient with a horseshoe kidney free of complications. Computed tomography showed two renal arteries and one renal vein on the left side, and the isthmus was perfused by several accessory arteries and veins. To demarcate the boundary of the isthmus, the left renal artery was ligated and cannulated for in situ perfusion. Furthermore, the isthmus was clamped, and the boundary of the isthmus was confirmed. The kidney was divided at the left margin of the perfused boundary. The cut ends of the isthmus were closed by sutures. The left kidney was transplanted into the right iliac fossa of the recipient. Asymptomatic fluid collection occurred on the cut surface at the isthmus of the donor, and this fluid decreased in due course. On the other hand, the recipient experienced no surgical complication or rejection, while maintaining serum creatinine levels of 2.00–2.20 mg/dL over a 22-month follow-up period. Horseshoe kidneys may be used for transplantation in selected cases after a detailed preoperative evaluation.

    Kidney transplant is a last resort to increase the life expectancy and quality of life in patients with renal failure. Aortic dissection is a disease that requires emergency intervention; it is characterized by sudden life-threatening back or abdominal pain. In the case described, constant chest pain that increased with respiration was present on examination of a 28-year-old man (85 kg, 173 cm) who presented at our emergency department complaining of severe back pain. He had undergone a kidney transplant in 2004 from his mother (live donor). He was diagnosed with acute Type II aortic dissection and was scheduled for emergent surgery. Because there were no surgical or anesthetic complications, the patient with 79 and 89 minutes aortic cross-clamping and cardiopulmonary bypass durations was sent, intubated, to intensive care unit. When nephrotoxic agents are avoided and blood flow is stabilized, cardiovascular surgery with cardio-pulmonary bypass may be performed seamlessly in patients who have undergone a kidney transplant.

  15. Proposal for a future delivery market for transplant organs.

    Schwindt, R; Vining, A R

    1986-01-01

    Improvements in surgical procedures and immunosuppressive practices have greatly increased the range and success rate of organ transplants. Unfortunately, supply does not meet demand, and demand is increasing. This paper documents the current level of unsatisfied demand for several transplantable organs, and argues that the extant system of altruistic organ donation is unlikely ever to provide adequate supply because of lack of incentives to donate and the ambiguity surrounding property rights over transplantable organs. A greater reliance on markets would help attenuate these problems. However, unorganized private spot markets for human organs are likely to be both inefficient and inequitable, and are perceived as morally offensive. A feasible alternative is an organized, publicly operated future delivery market, wherein an individual can contract, for valuable consideration, with a government agency for delivery of a specific organ upon death. The implementation of such a market would encounter difficult (but not intractable) problems such as price determination, the selection of a medium of exchange, and contractual issues, particularly the role of minors in such a system. Finally, it is argued that such a market is superior to the much-discussed compulsory expropriation alternative.

    Systemic hypertension after renal transplantation in children is frequent, occuring in 85% of the cases and may be the cause of severe neurologic complications. This can be due to multiple factors such as: Rejection, recurrence of initial disease, steroid, etc. ... Among those factors, renal transplant artery stenosis (RTAS) must be identified as it may be cured by angioplasty. We report our experience in 18 children having underwent angioplasty for RTAS. Angioplasty was performed under general anesthesia with 3F, 4F or 5F balloon catheters. Angioplasty was successful in 14 cases (77%) immediately (10 cases), progressively (2 cases) or after a successfully redilated recurrence (2 cases). 2 of the 4 failures were due to technical problems, a successful surgical treatment was then performed. The 2 others failures were explained by a severe transplant rejection. The complications were rare: 1 femoral artery thrombosis and spasms of the intra renal arteries but without repercussion on the renal function. In our experience, angioplasty seems to be the treatment of choice in RTAS in children. However the indications must be carefully established taking in account other possible causes of hypertension in such patients. (orig.)

    Obesity is a spreading epidemic associated with significant morbidity and mortality with a prevalence of over 36% worldwide. In the face of a growing epidemic, increasing medical costs, and the disappointing limitations of medical and lifestyle modification bariatric surgery was found to consistently lead to significant weight loss and improvement in obesity-associated comorbidities when compared to non-surgical interventions. Bariatric procedures fall within three basic categories: restrictive procedures, malabsorptive procedures, and procedures that combine both restrictive and malabsorptive mechanisms. Four major procedures are currently performed (most often laparoscopically): Roux-en-Y gastric bypass, biliopancreatic diversion with duodenal switch, adjustable gastric banding, and sleeve gastrectomy. Although the laparoscopic Roux-en-Y gastric bypass was the most frequently performed bariatric procedure, the laparoscopic sleeve gastrectomy has since become the most popular. Bariatric surgery currently has similar mortality rates to standard general surgical operations. Morevoer, bariatric surgery reduces mortality by the improvement and remission of obesity-related comorbidities. Newer minimally-invasive weight loss procedures and endoscopic methods continue to evolve as we expand our understanding of the intricacies of obesity and the effects of currently available surgical treatments.

    2009-09-06

    Surgical robotics is one of the most dynamically advancing areas of biomedical engineering. In the past few decades, computer-integrated interventional medicine has gained significance internationally in the field of surgical procedures. More recently, mechatronic devices have been used for nephrectomy, cholecystectomy, as well as in orthopedics and radiosurgery. Estimates show that 70% of the radical prostatectomies were performed with the da Vinci robot in the United States last year. Robot-aided procedures offer remarkable advantages in neurosurgery both for the patient and the surgeon, making microsurgery and Minimally Invasive Surgery a reality, and even complete teleoperation accessible. This paper introduces surgical robotic systems developed primarily for brain and spine applications, besides, it focuses on the different research strategies applied to provide smarter, better and more advanced tools to surgeons. A new system is discussed in details that we have developed together with the Johns Hopkins University in Baltimore. This cooperatively-controlled system can assist with skull base drilling to improve the safety and quality of neurosurgery while reducing the operating time. The paper presents the entire system, the preliminary results of phantom and cadaver tests and our efforts to improve the accuracy of the components. An effective optical tracking based patient motion compensation method has been implemented and tested. The results verify the effectiveness of the system and allow for further research.

  19. Allergy to Surgical Implants.

    Surgical implants have a wide array of therapeutic uses, most commonly in joint replacements, but also in repair of pes excavatum and spinal disorders, in cardiac devices (stents, patches, pacers, valves), in gynecological implants, and in dentistry. Many of the metals used are immunologically active, as are the methacrylates and epoxies used in conjunction with several of these devices. Allergic responses to surgical components can present atypically as failure of the device, with nonspecific symptoms of localized pain, swelling, warmth, loosening, instability, itching, or burning; localized rash is infrequent. Identification of the specific metal and cement components used in a particular implant can be difficult, but is crucial to guide testing and interpretation of results. Nickel, cobalt, and chromium remain the most common metals implicated in implant failure due to metal sensitization; methacrylate-based cements are also important contributors. This review will provide a guide on how to assess and interpret the clinical history, identify the components used in surgery, test for sensitization, and provide advice on possible solutions. Data on the pathways of metal-induced immune stimulation are included. In this setting, the allergist, the dermatologist, or both have the potential to significantly improve surgical outcomes and patient care.

    This paper presents an e-survey of current clinical practice of use of intra-operative diuretics during renal transplantation in the United Kingdom and a study to compare outcome of renal transplants carried out with or without intra-operative diuretics in our centre. An e-mail questionnaire to renal transplant surgeons exploring their practice of renal transplantation with or without intra-operative diuretics, the type of a diuretic/s if used and the relevant doses. An observational study comparing the outcome of renal transplant recipients, group no-diuretics (GND, n = 80) carried out from 2004 to 2008 versus group diuretics (GD n = 69) renal transplant recipients who received intra-operative diuretics over a one year period is presented. Outcome measures were incidence of delayed graft function and a comparison of graft survival in both groups. Forty surgeons answered from 18 transplant centres with a response rate of 67%. 13 surgeons do not use diuretics. Mannitol is used by 10/40, Furosemide 6/40 and 11 surgeons use a combination of both. In comparative study there was no significant overall difference in one year graft survival of GD versus GND (N = 65/69, 94% and 75/80, 94% respectively, p = 0.08) and the incidence of delayed graft function was also comparable (16/69, 23% and 21/80, 26% respectively, p = 0.07). The donor characteristics in both groups were comparable. The study showed variation in clinical practice on the use of intra-operative diuretics in renal transplantation and it did not demonstrate that the use of diuretics can improve renal graft survival.

    Full Text Available OBJECTIVE: Post-operative pulmonary complications significantly affect patient survival rates, but there is still no conclusive evidence regarding the effect of post-operative respiratory failure after liver transplantation on patient prognosis. This study aimed to predict the risk factors for post-operative respiratory failure (PRF after liver transplantation and the impact on short-term survival rates. DESIGN: The retrospective observational cohort study was conducted in a twelve-bed adult surgical intensive care unit in northern Taiwan. The medical records of 147 liver transplant patients were reviewed from September 2002 to July 2007. Sixty-two experienced post-operative respiratory failure while the remaining 85 patients did not. MEASUREMENTS AND MAIN RESULTS: Gender, age, etiology, disease history, pre-operative ventilator use, molecular adsorbent re-circulating system (MARS use, source of organ transplantation, model for end-stage liver disease score (MELD and Child-Turcotte-Pugh score calculated immediately before surgery were assessed for the two groups. The length of the intensive care unit stay, admission duration, and mortality within 30 days, 3 months, and 1 year were also evaluated. Using a logistic regression model, post-operative respiratory failure correlated with diabetes mellitus prior to liver transplantation, pre-operative impaired renal function, pre-operative ventilator use, pre-operative MARS use and deceased donor source of organ transplantation (p<0.05. Once liver transplant patients developed PRF, their length of ICU stay and admission duration were prolonged, significantly increasing their mortality and morbidity (p<0.001. CONCLUSIONS: The predictive pre-operative risk factors significantly influenced the occurrence of post-operative respiratory failure after liver transplantation.

    To determine the efficacy of focused parathyroidectomy for adenoma and total parathyroidectomy with forearm autotransplantation for hyperplasia in maintaining serum calcium levels. Sixteen patients were admitted in this time period. Eleven of these patients had primary hyperparathyroidism and 4 had secondary hyperparathyroidism due to chronic renal failure. Pre-operative localization was done with Sestamibi scan and ultrasound of neck while methylene blue was used for intra-operative localization. All patients with primary hyperparathyroidism had single gland disease and were treated with focused parathyroidectomy. In 4 patients with parathyroid hyperplasia, total parathyroidectomy with forearm autotransplantation was done. In the postoperative period, 3 patients developed hypocalcemia but they were managed on oral calcium and vitamin-D supplements. All of the remaining patients became normocalcaemic and there were no major complications. Mean hospital stay was 7-days. Focused parathyroidectomy for single gland disease and total parathyroidectomy with forearm auto-transplantation for hyperplasia was a satisfactory treatment for patients in this series. (author)

    The formation of urinary tract stones following renal transplantation is a rare complication. The clinical features of stones after transplantation differ from those of non-transplant patients. Renal colic or pain is usually absent and rarely resembles acute rejection. We retrospectively studied 849 consecutive kidney transplant patients in The Rogosin Institute/The Weill-Cornell Medical Center, New York who were transplanted between 1980 and 1997 and had functioning grafts for more than 3 months, to determine the incidence of stone formation, composition, risk factors and patient outcome. At our center, urinary stones were diagnosed in 15 patients (1.8%) of 849 functioning renal grafts for 3 or more months. Of the 15 patients, 10 were males and 5 were females in their third and fourth decade. Eight patients received their transplant from living donors and 7 from cadaveric donors. The stones were first diagnosed between 3 and 109 months after transplantation (mean 17.8 months) and 5 patients had recurrent episodes. The stones were located in the bladder in 11 cases (73.3%), transplanted kidney in 3 cases and in multiple sites in one case. The size of stones varied from 3.4 mm to 40 mm (mean 12 mm). The composition of stones was a mixed form of calcium oxalate and calcium phosphate in 5 cases and 4 patients had infected stones consisting of struvite or mixed form of struvite and calcium phosphate. Factors predisposing to stone formation included tertiary hyperparathyroidism (n = 8), hypercalciuria (n = 5), recurrent urinary tract infection (n = 5), hypocitraturia (n = 4), and obstructive uropathy (n = 2). Many cases had more than one risk factor. Clinically, painless hematuria was observed in 6 patients and dysuria without bacteriuria in 5 patients. None had renal colic or severe pain at any time. There were no changes in graft function at diagnosis and after removal of stones. Five patients passed stones spontaneously and 8 patients underwent cystoscopy for stone

    Human uterus transplantation (UTx) is currently under investigation as a treatment for uterine infertility. Without a uterus transplant, the options available to women with uterine infertility are adoption or surrogacy; only the latter has the potential for a genetically related child. UTx will offer recipients the chance of having their own pregnancy. This procedure occurs at the intersection of two ethically contentious areas: assisted reproductive technologies (ART) and organ transplantation. In relation to organ transplantation, UTx lies with composite tissue transplants such as face and limb grafts, and shares some of the ethical concerns raised by these non-life saving procedures. In relation to ART, UTx represents one more avenue by which a woman may seek to meet her reproductive goals, and as with other ART procedures, raises questions about the limits of reproductive autonomy. This paper explores the ethical issues raised by UTx with a focus on the potential gap between women's desires and aspirations about pregnancy and the likely functional outcomes of successful UTx. © 2011 Blackwell Publishing Ltd.

    Full Text Available Protein-energy malnourishment is commonly encountered in patients with end-stage liver disease who undergo liver transplantation. Malnutrition may further increase morbidity, mortality and costs in the post-transplantation setting. The importance of carefully assessing the nutritional status during the work-up of patients who are candidates for liver replacement is widely recognized. The metabolic abnormalities induced by liver failure render the conventional assessment of nutritional status to be challenging. Preoperative loss of skeletal muscle mass, namely, sarcopenia, has a significant detrimental impact on post-transplant outcomes. It is essential to provide sufficient nutritional support during all phases of liver transplantation. Oral nutrition is preferred, but tube enteral nutrition may be required to provide the needed energy intake. Herein, the latest currently employed perioperative nutritional interventions in liver transplant recipients are thoroughly illustrated including synbiotics, micronutrients, branched-chain amino acid supplementation, immunonutrition formulas, fluid and electrolyte balance, the offering of nocturnal meals, dietary counselling, exercise and rehabilitation.

    Solid organ transplantation is an accepted therapy for end-stage diseases of the kidneys, liver, heart, and lungs. Unfortunately, transplantation is associated with infectious complications. Here, we present a case report of Prototheca wickerhamii olecranon bursitis and review all of the cases in solid organ transplant (SOT) recipients published in the literature to date. In our patient, the infection resolved with surgical therapy and limited antifungal therapy, and no symptoms have recurred over 24 months of follow-up. A review of the literature suggests that 50% of SOT recipients with Prototheca infection present with disseminated infection, and the overall mortality is 75%. More studies are required to determine the optimal management of protothecosis in this population. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  17. Elliptical donor stereoscopically assisted micrografting as an approach to further refinement in hair transplantation.

    1994-12-01

    Multiple surgical methods are currently used for hair transplantation. Each method has a specific technique, morbidity, and relatively predictable cosmetic result. To describe a methodology that combines elliptical excision of donor tissue and dissection under stereoscopic magnification into small grafts to obtain an improved final cosmetic result. For the purposes of this paper, any graft small enough to be easily inserted into a 16-, 18-, or 20-gauge needle tunnel will be referred to as a micrograft. Three hundred thirty patients underwent transplantation by this method over a 6-year period. All patients were photographed before, during, and upon completion to monitor results. Cosmetic results as documented by examination and photography represent a further refinement due to the large number and small size of grafts placed. The author considers the method described as a viable alternative technique in hair transplantation for both limited and extensive androgenetic alopecia.

    Auxiliary partial orthotopic liver transplant (APOLT) is a treatment technique for people who have acute hepatic failure secondary to fulminant hepatic failure and might ultimately recover normal liver function. This surgical procedure is complicated, involving the placement of a liver graft while maintaining viability of the remaining native portion of the liver. This method allows the native liver to recover hepatic function, therefore eliminating the need for long-term immunosuppression, as is typically needed in post-transplant settings. Postoperative imaging in these cases can be challenging given the complex anatomy, specifically the vascular anastomosis. Therefore it is important for radiologists and clinicians to be aware of the anatomy as well as the variable imaging appearances of the liver. We review the imaging findings in children who have undergone auxiliary partial orthotopic liver transplant (APOLT). (orig.)

    2014-10-01

    Patients with pulmonary hypertension are some of the most challenging for an anaesthesiologist to manage. Pulmonary hypertension in patients undergoing surgical procedures is associated with high morbidity and mortality due to right ventricular failure, arrhythmias and ischaemia leading to haemodynamic instability. Lung transplantation is the only therapeutic option for end-stage lung disease. Patients undergoing lung transplantation present a variety of challenges for anaesthesia team, but pulmonary hypertension remains the most important. The purpose of this article is to review the anaesthetic management of pulmonary hypertension during lung transplantation, with particular emphasis on the choice of anaesthesia, pulmonary vasodilator therapy, inotropic and vasopressor therapy, and the most recent intraoperative monitoring recommendations to optimize patient care.

  20. Transjugular Intrahepatic Portosystemic Shunt for Maintenance of Portal Venous Patency in Liver Transplant Candidates

    Directory of Open Access Journals (Sweden)

    Ron Charles Gaba

    2013-01-01

    Full Text Available Maintenance of portal venous patency is vital to liver transplant candidates, as the presence of portal vein thrombosis (PVT adversely impacts clinical outcomes by increasing surgical complexity and decreasing postoperative survival. By enhancing portal venous blood flow, transjugular intrahepatic portosystemic shunt (TIPS creation may enable clearance of PVT and preservation of portal venous patency in cirrhotic patients. Herein, we describe four cases in which TIPS produced and sustained an open portal venous system in liver transplant candidates with partial PVT. All patients demonstrated rapid and effective flow-enabled clearance of clot and intermediate to long-term preservation of portal venous flow. On this basis, we propose that maintenance of portal venous patency in liver transplant candidates with partial PVT represents a developing indication for TIPS.

  1. Brain Tumor Tropism of Transplanted Human Neural Stem Cells Is Induced by Vascular Endothelial Growth Factor

    Directory of Open Access Journals (Sweden)

    Nils Ole Schmidt

    2005-06-01

    Full Text Available The transplantation of neural stem cells (NSCs offers a new potential therapeutic approach as a cell-based delivery system for gene therapy in brain tumors. This is based on the unique capacity of NSCs to migrate throughout the brain and to target invading tumor cells. However, the signals controlling the targeted migration of transplanted NSCs are poorly defined. We analyzed the in vitro and in vivo effects of angiogenic growth factors and protein extracts from surgical specimens of brain tumor patients on NSC migration. Here, we demonstrate that vascular endothelial growth factor (VEGF is able to induce a long-range attraction of transplanted human NSCs from distant sites in the adult brain. Our results indicate that tumorupregulated VEGF and angiogenic-activated microvasculature are relevant guidance signals for NSC tropism toward brain tumors.

    Encapsulating peritoneal sclerosis is a rare complication of long-term peritoneal dialysis ranging from moderate inflammation of peritoneal structures to severe sclerosing peritonitis and encapsulating peritoneal sclerosis. Complicated it, ileus may occur during or after peritoneal dialysis treatment or after kidney transplant. We sought to evaluate 3 posttransplant encapsulating peritoneal sclerosis through clinical presentation, radiologic findings, and outcomes. We analyzed 3 renal transplant patients with symptoms of encapsulating peritoneal sclerosis admitted posttransplant to our hospital with ileus between 2012 and 2013. Conservative treatment was applied to the patients whenever necessary to avoid surgery. One patient improved with medical therapy. Surgical treatment was delayed and we decided it as a last resort, in 2 cases with no response to conservative treatment for a long time. Finally, patients with peritoneal dialysis history should be searched carefully before renal transplant for intermittent bowel obstruction story.

    In 1958 Francis Moore described the orthotopic liver transplantation technique in dogs. In 1963, Starzl et al. performed the first liver transplantation. In the first five liver transplantations no patient survived more than 23 days. In 1967, stimulated by Calne who used antilymphocytic serum, Starzl began a successful series of liver transplantation. Until 1977, 200 liver transplantations were performed in the world. In that period, technical problems were overcome. Roy Calne, in 1979, used the first time cyclosporine in two patients who had undergone liver transplantation. In 1989, Starzl et al. reported a series of 1,179 consecutives patients who underwent liver transplantation and reported a survival rate between one and five years of 73% and 64%, respectively. Finally, in 1990, Starzl et al. reported successful use of tacrolimus in patents undergoing liver transplantation and who had rejection despite receiving conventional immunosuppressive treatment. Liver Transplantation Program was initiated at Hospital Israelita Albert Einstein in 1990 and so far over 1,400 transplants have been done. In 2013, 102 deceased donors liver transplantations were performed. The main indications for transplantation were hepatocellular carcinoma (38%), hepatitis C virus (33.3%) and alcohol liver cirrhosis (19.6%). Of these, 36% of patients who underwent transplantation showed biological MELD score > 30. Patient and graft survival in the first year was, 82.4% and 74.8%, respectively. A major challenge in liver transplantation field is the insufficient number of donors compared with the growing demand of transplant candidates. Thus, we emphasize that appropriated donor/receptor selection, allocation and organ preservation topics should contribute to improve the number and outcomes in liver transplantation. PMID:25993082

    Bone marrow transplantation after irradiation is successful in only a part of the affected patients. The Chernobyl accident added to our knowledge: BMT can save life after whole-body irradiation with a dose exceeding 7-8 Gy. A timely decision on transplantation after a nuclear accident is difficult to make (rapid determination of homogeneity and type of radiation and the total dose. HL-A typing in lymphopenia, precise identification of radiation damage to other target organs, etc.). Further attention is to be paid to the treatment. Transplantations in case of malignities (especially hematologic ones) and other diseases will add to our knowledge and will lead to more simple procedures. (author). 3 figs., 1 tab., 12 refs

    Chagas disease is an endemic disease in Latin America that is increasingly found in non-endemic areas all over the world due to the flow of migrants from Central and South America. We present the case of a Brazilian immigrant in Portugal who underwent orthotopic heart transplantation for end-stage Chagas cardiomyopathy. Immunosuppressive therapy included prednisone, mycophenolate mofetil and tacrolimus. Twelve months after the procedure she is asymptomatic, with good graft function, and with no evidence of complications such as graft rejection, opportunistic infections, neoplasms or reactivation of Trypanosoma cruzi infection. By reporting the first case in Portugal of heart transplantation for Chagas cardiomyopathy, we aim to increase awareness of Chagas disease as an emerging global problem and of Chagas cardiomyopathy as a serious complication for which heart transplantation is a valuable therapeutic option.

    There are few reports of the outcome of renal transplantation in patients with severe left ventricular (LV) impairment. We describe three men with chronic disabling heart failure associated with LV dysfunction in whom a remarkable improvement in cardiac function followed renal transplantation. Transplantation may offer the prospect of successful rehabilitation in these circumstances. Undue pessimism as to the prognosis in such patients is unwarranted.

    It is well recognized that patients with end stage renal diseases (ESRD) have hyper-plastic parathyroid glands. In most patients, a decrease in parathyroid hormone (PTH) occurs by about 1 year after renal transplantation. However, some renal transplant recipients continue to have elevated level of PTH. We prospectively evaluated 121 patients undergoing renal transplantation between August 2000 and 2002. The duration of dialysis, calcium (Ca), phosphorus (P), albumin, creatinine and iPTH levels were recorded prior to transplantation and three months and one year after transplantation. These 121 patients were on dialysis for an average period of 17.4 months prior to transplantation. An increase in the serum Ca and a decrease in serum P and iPTH level was seen in the patients after transplantation (P< 0.001). Hyperparathyroidism was in 12 (9.9%) and 7 (5.7%) patients three months and one year after transplantation respectively. Elderly patients and patients with longer duration on dialysis had an increased risk of developing post transplant hyperparathyroidism and hypercalcemia in the first year post transplant (P< 0.05). In conclusion age and duration on dialysis before transplantation seems to be important risk factors for post transplant hyperparathyroidism. (author)

    Full Text Available Aim: evaluation of the incidence and the pattern of vessel complications, efficacy of the prophylactic anticoagulation therapy after kidney transplantation. Materials and methods. From March 2007 till January 2013 421 patients: 230 men (54,6% and 191 women (45,4%; mean age 43,07 ± 11,62 undergone 429 kidney transplantations in the department of pancreas and kidney transplantation of the Scientific-Research Institute of Emergency Care named after N.V. Sklifosovsky. In order to evaluate the condition and the function of the kidney transplant ultrasound investigation (daily andacquisition(weekly wereused. In cases of kidney dysfunction and assumption of vessel complications we used computerized tomography. Besides, we used daily analysis of biochemical and clinical parameters of blood and urine. Results. The most common vessel complication was the thrombosis of the microvasculature of the kidney transplant due to acute humoral and combined rejection resistant to antirejection therapy (n = 9; 2,1%; in 4 cases there was a breakage of the transplant due to the acute rejection and the urgent transplantatectomy in an effort to save the patient; thrombosis of the transplantat artery occurred in 1 case (0,23%; we observed 2 cases (0,46% of the artery stenosis and 2 cases (0,46% of venous thrombosis. Conclusion. Summary frequency of vessel complications in our clinic, including thrombosis due to rejection, was 3,49%. It fully corresponds with data obtained from the global medical community. The incidence of great vessel thrombosis was less than 1% which indicates the adequate prophylactic anticoagulation therapy. For the benefit of early diacrisis of complications Doppler sonography is needed. In case of assumption of vessel complications urgent acquisition, computerized tomography and/ or angiography are to be held.

    Full Text Available Riboflavin is a member of redox enzymes involved in fatty acid oxidation and energy generation. Important role of this vitamin is in reproductive function. Exchange of transformation of riboflavin in animal tissues and cells of microorganisms include reactions that lead to synthesis and subsequent collapse of FMN and FAD. It is involved in enhancing antitumor activity of many anticancer drugs, as well as activation of the immune system to kill tumor cells. Issues of transport of riboflavin and its derivatives in animals have been studied enough. Investigations of changes of the balance of riboflavin and its metabolites in muscular tissues before transplantation in rats from one litter and at operation without replanting were conducted, based on the Udenfriend method of flavin determination. Transplantation in the experiment was carried out on white non-linear male rats weighing 180–300 g. Animals were taken out of the experiment by passing electric current through the medulla. Belly muscular tissue was taken from donor rats of the same litter, and that tissue was sewn to homological muscular tissue of the recipient. The same procedure was carried out with femoral muscular tissue. In the course of operation without replanting the same manipulations have been made except for transplantation stage (for determination of the effect of surgical intervention. Tissue not subject to any surgical intervention served as a control. Parameters of the study were measured on the first, third and seventh days after transplantation. Transplantation of muscular tissue caused no changes in total flavin amount. Content of RF + FMN after transplantation of muscular tissue in rats of the same litter decreased in femoral muscular tissue of the recipient. Transplantation of muscular tissues in rats from the same litter lead to increase in FAD amount in femoral muscular tissue of the donor and recipient on the third day of the experiment.

    2017-07-01

    Ischemia-reperfusion injury is a composite of the injury sustained during a period of reduced or absent blood flow to a tissue or organ and the additional insult sustained on reperfusion, which limits the amount of tissue that can be salvaged. Ischemia-reperfusion injury is the predominant insult during kidney transplantation, contributing to graft dysfunction, increased rates of acute rejection, and reduced rejection-free graft survival. In this review, we discuss the potential therapeutic benefits of a cost-effective and low-risk intervention, ischemic preconditioning, and its potential for improving kidney function following transplantation.

  1. Pacemaker Use Following Heart Transplantation

    Science.gov (United States)

    Mallidi, Hari R.; Bates, Michael

    2017-01-01

    Background: The incidence of permanent pacemaker implantation after orthotopic heart transplantation has been reported to be 2%-24%. Transplanted hearts usually exhibit sinus rhythm in the operating room following reperfusion, and most patients do not exhibit significant arrhythmias during the postoperative period. However, among the patients who do exhibit abnormalities, pacemakers may be implanted for early sinus node dysfunction but are rarely used after 6 months. Permanent pacing is often required for atrioventricular block. A different cohort of transplant patients presents later with bradycardia requiring pacemaker implantation, reported to occur in approximately 1.5% of patients. The objectives of this study were to investigate the indications for pacemaker implantation, compare the need for pacemakers following bicaval vs biatrial anastomosis, and examine the long-term outcomes of heart transplant patients who received pacemakers. Methods: For this retrospective, case-cohort, single-institution study, patients were identified from clinical research and administrative transplant databases. Information was supplemented with review of the medical records. Standard statistical techniques were used, with chi-square testing for categorical variables and the 2-tailed t test for continuous variables. Survival was compared with the use of log-rank methods. Results: Between January 1968 and February 2008, 1,450 heart transplants were performed at Stanford University. Eighty-four patients (5.8%) were identified as having had a pacemaker implanted. Of these patients, 65.5% (55) had the device implanted within 30 days of transplantation, and 34.5% (29) had late implantation. The mean survival of patients who had an early pacemaker implant was 6.4 years compared to 7.7 years for those with a late pacemaker implant (Ppacemaker implantation. Starting in 1997, a bicaval technique was used for implantation. The incidence of pacemaker implantation by technique was 2.0% for

    After lung transplantation, pulmonary vein thrombosis is a rare, potentially life-threatening adverse event arising at the pulmonary venous anastomosis that typically occurs early and presents as graft failure and hemodynamic compromise with an associated mortality of up to 40%. The incidence, presentation, outcomes, and treatment of late pulmonary vein thrombosis remain poorly defined. Management options include anticoagulant agents for asymptomatic clots, and thrombolytic agents or surgical thrombectomy for hemodynamically significant clots. We present a rare case highlighting a delayed presentation of pulmonary vein thrombosis occurring longer than 2 weeks after lung transplantation and manifesting clinically as graft failure secondary to refractory pulmonary edema. The patient was treated successfully with surgical thrombectomy and remains well. We recommend a high index of suspicion of pulmonary vein thrombosis when graft failure after lung transplantation occurs and is not responsive to conventional therapy, and consideration of investigation with transesophageal echocardiography or computed tomography with venous phase contrast in such patients even more than 2 weeks after lung transplantation.

    Heart rate variability is primarily regulated by the autonomic nervous system. Heart transplant recipients undergo surgical denervation of the graft, which results in interruption of autonomic innervation with resultant diminished heart rate variability although some degree of autonomic control may return. This study aimed to characterize heart rate variability in this population. We report a retrospective review of Holter monitor data from transplanted patients between 2005 and 2013. Studies with significant atrial or ventricular arrhythmias were excluded. We evaluated changes over time and compared standard time domain measures to published pediatric normal values. Data were reviewed from 582 monitors in 152 patients. We found that pediatric heart transplant recipients have lower heart rate variability than age-matched controls and higher average heart rate in recipients older than 3 years. There is an increase in measures of variability through the first 3 years post-transplant with plateau after that time. Surgical technique in regard to interruption of the vagus nerve does not affect variability, nor does underlying congenital vs acquired heart disease. © 2017 John Wiley & Sons A/S.

    Persistent hyperparathyroidism (HPT) with hypercalcemia is prevalent after transplant and is considered a risk factor for progressive bone loss and fractures and vascular calcification, as well as the development of tubulointerstitial calcifications of renal allografts and graft dysfunction. The subtotal parathyroidectomy is the standard treatment, although currently it has been replaced by the calcimimetic cinacalcet. The hypothesis of this study is that subtotal parathyroidectomy is superior to cinacalcet for treatment of persistent secondary parathyroidectomy post renal transplant, with minimal morbidity and significantly it reduces the cost of treatment after transplantation. We report our long-term clinical experience with either cinacalcet or parathyroidectomy in 59 kidney transplant recipients with hyperparathyroidism. Group one included medical treatment with cinacalcet and had 45 patients while parathyroidectomy patients (group 2) were 16 patients with two of them excluded because of surgical failure. No difference was found between groups for any parameter. A greater short-term change of calcium and phosphorus homeostasis obtained by surgery than by cinacalcet, and in long term change, no significant difference between the two groups. The main findings of this study are that correction of severe hyperparathyroidism was similar in both surgical and cinacalcet groups with the absence of a difference of long-term serum iPTH 1-84 levels between the two groups.

    Most speech disorders of childhood are treated with speech therapy. However, two conditions, ankyloglossia and velopharyngeal dysfunction, may be amenable to surgical intervention. It is important for surgeons to work with experienced speech language pathologists to diagnose the speech disorder. Children with articulation disorders related to ankyloglossia may benefit from frenuloplasty. Children with velopharyngeal dysfunction should have standardized clinical evaluation and instrumental asseessment of velopharyngeal function. Surgeons should develop a treatment protocol to optimize speech outcomes while minimizing morbidity. Copyright © 2014 Elsevier Inc. All rights reserved.

    A state of the art of surgical method of abortion focusing on safety and practical aspects. A systematic review of French-speaking or English-speaking evidence-based literature about surgical methods of abortion was performed using Pubmed, Cochrane and international recommendations. Surgical abortion is efficient and safe regardless of gestational age, even before 7 weeks gestation (EL2). A systematic prophylactic antibiotics should be preferred to a targeted antibiotic prophylaxis (grade A). In women under 25 years, doxycycline is preferred (grade C) due to the high prevalence of Chlamydia trachomatis. Systematic cervical preparation is recommended for reducing the incidence of complications from vacuum aspiration (grade A). Misoprostol is a first-line agent (grade A). When misoprostol is used before a vacuum aspiration, a dose of 400 mcg is recommended. The choice of vaginal route or sublingual administration should be left to the woman: (i) the vaginal route 3 hours before the procedure has a good efficiency/safety ratio (grade A); (ii) the sublingual administration 1 to 3 hours before the procedure has a higher efficiency (EL1). The patient should be warned of more common gastrointestinal side effects. The addition of mifepristone 200mg 24 to 48hours before the procedure is interesting for pregnancies between 12 and 14 weeks gestations (EL2). The systematic use of nonsteroidal anti-inflammatory drugs is recommended for limiting the operative and postoperative pain (grade B). Routine vaginal application of an antiseptic prior to the procedure cannot be recommended (grade B). The type of anesthesia (general or local) should be left up to the woman after explanation of the benefit-risk ratio (grade B). Paracervical local anesthesia (PLA) is recommended before performing a vacuum aspiration under local anesthesia (grade A). The electric or manual vacuum methods are very effective, safe and acceptable to women (grade A). Before 9 weeks gestation

    Little is known about how parents and youth perceive their roles in post-transplant management and how this relates to post-transplant adherence. The goals of this study are to (1) describe a new measure, the TRQ, (2) to describe parent and child performance on the TRQ, and to (3) determine the relationship between the TRQ and adherence. We hypothesized that older youth would describe higher post-transplant self-care behaviors, parents would underestimate youth self-care, and greater parent involvement would be associated with better adherence. Participants included 59 parent-child dyads. Inclusion criteria included: (i) youth aged 7-18 yr and (ii) at least three months post-kidney or post-liver transplant. Parents and youth completed the TRQ, and adherence was measured by s.d. of sequential immunosuppressant blood levels. Youth perceived greater levels of self-care than their parents perceived. Older youth reportedly engaged in more self-care than younger youth. Less than 25% of the sample was non-adherent, and non-adherence was unrelated to performance on the TRQ. The TRQ may have utility as a clinical tool to address areas for improvement in youth self-care. The high degree of parental involvement likely explains the high degree of adherence in this sample. © 2013 John Wiley & Sons A/S.

    Full Text Available A endomiocardiofibrose é uma doença comum em países tropicais, particularmente Uganda e Nigéria, e pode acometer tanto o ventrículo esquerdo como direito, gerando uma insuficiência cardíaca restritiva que, além dos sintomas clássicos, manifesta-se por ascite desproporcional ao edema periférico. Apresentamos o caso de uma portadora de endomiocardiofibrose refratária ao tratamento clínico, submetida ao tratamento cirúrgico com melhora clínica por curto período, voltando a apresentar sintomas incapacitantes três meses após a cirurgia de ressecção de fibrose endomiocárdica e plastia tricúspide. A paciente foi então submetida a transplante cardíaco ortotópico bicaval, com boa evolução clínica. É o primeiro caso de transplante cardíaco nesta doença, mostrando-se uma alternativa de tratamento promissora.Endomyocardial fibrosis is a common disease in tropical countries, particularly Uganda and Nigeria. It may affect the right and left ventricles, creating restrictive heart failure, which, in addition to the classical symptoms, manifests as ascites disproportional to peripheral edema. We report the case of a female patient with endomyocardial fibrosis refractory to clinical treatment, who underwent surgical treatment with clinical improvement for a short period. Three months after the surgery for resection of the endomyocardial fibrosis and tricuspid valvuloplasty, the disabling symptoms reappeared. Then the patient underwent bicaval orthotopic heart transplantation, which had a good clinical outcome. This was the first case of heart transplantation for the treatment of endomyocardial fibrosis, which proved to be a promising alternative.

  11. ABO-incompatibility in solid organ transplantation.

    The most important transplantation antigen system in solid organ transplantation is the ABO histo-blood group system. Crossing the ABO barrier in solid organ transplantation is usually not done except for emergency liver transplantations. Early experiences of crossing the ABO barrier in renal transplantation were very disappointing. In the 1970s, clinical trials were started transplanting kidneys of subgroup A2 into blood group O recipients. The tissues of the A2 subgroup expresses reduced amount of A antigens compared to subgroup A1 and the recipients had no special pretreatment and standard immunosuppression. A number of early graft losses were experienced but the trial also resulted in several long time surviving grafts. A few centres have adapted the concept of A2 to non A kidney transplantations with successful results, when the recipient anti-A titres are low or reduced prior to transplantation. In the early 1980s one group successfully transplanted A1 and B kidneys from living related donors across the ABO-barrier using an immunosuppressive protocol consisting of quadruple drugs and splenectomy and this protocol was adapted by a few other groups. In Japan, where cadaver donors are available in very limited number, the largest number of ABO-incompatible transplantations have been performed. Altogether more than 300 ABO-incompatible kidney transplantations have been performed in more than 40 centres since 1989. ABO-incompatible liver transplantations have been performed mainly in emergency cases and the results have generally been inferior to ABO-compatible grafts. In children below the age of three years, liver transplantations across the ABO-barrier have been quite successful especially with living related donors. Very few ABO-incompatible heart/heart-lung/lung-transplantations have been reported with a few successful cases, but the majority have been failures. Recently a series of ABO-incompatible heart transplants performed in small children have been

    Transplant tourism is the term used for patients who travel abroad for transplantation. Transplant tourism has always been surrounded with controversy regarding how these organs were obtained, the donor's care after transplantation, and the recipient outcome. Many authors have found that the outcome of the recipients in transplant tourism is inferior to those transplanted in their own countries. However, most these studies were small, with the latest one including only 33 patients. Here, we describe the outcome of 93 patients who were transplanted abroad compared with local transplantation. All transplant patients who were followed up at our Nephrology Clinic from 1998 until 2008 were identified using our data base system. We selected patients transplanted from 2003 and forward because the computerized system for laboratory and electronic records began operation that year. A total of 165 patients were identified (93 in the tourist group and 72 in the local one). Transplant tourists had a higher rate of acute rejection in the first year compared with local transplantation (27.9% vs. 9.9, P=0.005), higher mean creatinine at 6 months and 1 year (120 vs. 101 micromol/L, P=0.0007, 113 vs. 98 micromol/L, P=0.008). There was no statistical difference in graft or patient survival in 1 or 2 years after transplantation. However, transplant tourist had a higher rate of cytomegalovirus infection (15.1% vs. 5.6%, P=0.05) and hepatitis C seroconversion (7.5% vs. 0%, P=0.02). Transplant tourists had a more complex posttransplantation course with higher incidence of acute rejection and infectious complications.

    Since 1974, 69 patients with extensive defects have undergone reconstruction by microsurgical composite tissue transplantation. Using this method, donor composite tissue is isolated on its blood supply, removed to a distant recipient site, and the continuity of blood flow re-established by microvascular anastomoses. In this series, 56 patients (81%) were completely successful. There have been eight (12%) failures, primarily in the extremities. There have been five (7%) partial successes, (i.e., a microvascular flap in which a portion was lost requiring a secondary procedure such as a split thickness graft). In those patients with a severely injured lower extremity, the failure rate was the greatest. Most of these were arterial (six of seven). These failures occurred early in the series and were thought to be related to a severely damaged recipient vasculature. This problem has been circumvented by an autogenous interpositional vein graft, permitting more mobility of flap placement. In the upper extremity, all but one case were successful. Early motion was permitted, preventing joint capsular contractures and loss of function. Twenty-three cases in the head and neck region were successful (one partial success). This included two composite rib grafts to the mandible. Prolonged delays in reconstruction following extirpation of a malignancy were avoided. A rapid return to society following complete reconstruction was ensured. Nine patients presented for reconstruction of the breast and thorax following radical mastectomy. All were successfully reconstructed with this new technique except one patient. Its many advantages include immediate reconstruction without delayed procedures and no secondary deformity of the donor site. Healthy, well vascularized tissue can now be transferred to a previously irradiated area with no tissue loss. This new method offers many advantages to older methods of reconstruction. Length of hospital stay and immobilization are reduced. The

    Kidney transplants are the most common solid organ abdominal transplant and are occasionally performed simultaneously with pancreas transplants in diabetic patients. Preoperative evaluation of potential transplant recipients should focus on the potential for occult cardiovascular disease while also screening for other signs of end-organ dysfunction. Intraoperatively, it is of utmost importance to ensure adequate graft perfusion to limit the risk of postoperative graft dysfunction or rejection. Postoperative care of the kidney or pancreas transplant patient should focus on ensuring normalization of volume status, electrolyte concentrations, and glycemic control.

    Along with a decline in interest in general surgery among United States medical school graduates, reports indicate a decrease in the amount of time students are spending on their surgical clerkship. In an effort to offer early exposure to general surgery as well as to equip students with the basic surgical skills that will enhance their third-year clerkship experience, we developed a preclinical surgical experience. Students were surveyed to determine whether the surgical selective changed student level of comfort with basic surgical skills. Surveys were administered, preexperience and postexperience to the medical students enrolled in the surgery selective. The students were asked to rate their comfort level with 12 unique surgical skills. Comfort with the task was evaluated using a 10-point Likert scale. Analyses were conducted to evaluate the impact of the surgical experience on student comfort levels with the surgical skills. The self-reported comfort levels of students increased significantly after the experience in all 12 areas. The greatest change in comfort level (greater than or equal to mean difference of 4) occurred in the surgical technique categories: knot tying (mean difference: 4.9, p < 0.0001), suturing (mean difference: 4.85, p < 0.0001), correctly making an incision (mean difference: 4.95, p < 0.0001), using a needle driver (mean difference: 5.35, p < 0.0001), holding pickups (mean difference: 4.6, p < 0.0001), use of laparoscopic instruments (mean difference: 4.8, p < 0.0001), and use of surgical simulators (mean difference: 6.0, p < 0.0001). Our preclinical surgical experience serves as a model of an effective modality providing early exposure to general surgery. The experience provides trainees with basic surgical skills well before they begin their third-year clerkships. Copyright © 2012 Association of Program Directors in Surgery.

    The deployment of surgical assets has been driven by mission demands throughout years of military operations in Iraq and Afghanistan. The transition to the highly expeditious Golden Hour Offset Surgical Transport Team (GHOST- T) now offers highly mobile surgical assets in nontraditional operating rooms; the content of the surgical instrument sets has also transformed to accommodate this change. The 102nd Forward Surgical Team (FST) was attached to Special Operations assigned to southern Afghanistan from June 2015 to March 2016. The focus was to decrease overall size and weight of FST instrument sets without decreasing surgical capability of the GHOST-T. Each instrument set was evaluated and modified to include essential instruments to perform damage control surgery. The overall number of main instrument sets was decreased from eight to four; simplified augmentation sets have been added, which expand the capabilities of any main set. The overall size was decreased by 40% and overall weight decreased by 58%. The cardiothoracic, thoracotomy, and emergency thoracotomy trays were condensed to thoracic set. The orthopedic and amputation sets were replaced with an augmentation set of a prepackaged orthopedic external fixator set). An augmentation set to the major or minor basic sets, specifically for vascular injuries, was created. Through the reorganization of conventional FST surgical instrument sets to maintain damage control capabilities and mobility, the 102nd GHOST-T reduced surgical equipment volume and weight, providing a lesson learned for future surgical teams operating in austere environments. 2017.

    Full Text Available Introduction : Infections caused by metacestode stage of the Echinococcus granulosus in humans result in disease named cystic echinococcosis. Aim: To present the outcomes of patients treated surgically for cystic echinococcosis of the liver. Material and methods : One hundred and nineteen patients treated in the period between 1989 and 2014 due to E. granulosus infection in the Department of General, Transplant, and Liver Surgery, Medical University of Warsaw were selected for this retrospective study. Diagnostic protocol included imaging examinations, i.e. ultrasonography and computed tomography of the abdomen. Blood samples where used to proceed sequential enzyme-linked immunosorbent assay (ELISA using Em2plus antigen as well as polymerase chain reaction (PCR to detect E. granulosus . Results : Surgery was the choice for treatment for almost all of the patients (98.3%. In 40 (34.2% patients right hemihepatectomy, in 19 (16.2% patients left hemihepatectomy, and in 21 (17.9% patients bisegementectomy were performed. Postoperative complications occurred in 4 (3.4% patients. In 3 patients biliary fistula requiring endoscopic treatment was observed, and 1 patient had subdiaphragmatic abscess successfully treated with drainage under ultrasound guidance. None of the patients died in the postoperative period, and the 1-, 5-, and 10-year survival rates were 100.0%, 90.9%, and 87.9%, respectively. Conclusions : Surgical treatment of the symptomatic cystic echinococcosis is the modality of choice for E. granulosus infection of the liver. Despite substantial development of diagnostic methods and new management opportunities, echinococcal infection still presents a challenge for epidemiologists, pharmacologists, and clinicists.

    We aim to illustrate the applications of 3-dimensional (3-D) photogrammetry for surgical planning and longitudinal assessment of the volumetric changes in hemifacial microsomia. A 3-D photogrammetric system was employed for planning soft tissue expansion and transplantation of a vascularized scapular flap for a patient with hemifacial microsomia. The facial deficiency was calculated by superimposing a mirror of the normal side on the preoperative image. Postsurgical volumetric changes were monitored by serial superimposition of 3-D images. A total of 31 cm(3) of tissue expansion was achieved within a period of 4 weeks. A scapular free flap measuring 8 cm × 5 cm was transplanted to augment the facial deficiency. Postsurgical shrinkage of the flap was observed mainly in the first 3 months and it was minimal thereafter. 3-D photogrammetry can be used as a noninvasive objective tool for assessing facial deformity, planning, and postoperative follow-up of surgical correction of facial asymmetry.
