Liver Transplantation Using Prolonged Cold Ischemia Time Grafts Preserved With Institute George-Lopez-1 Solution.

Institute George-Lopez-1 (IGL-1) solution is a preservation solution with lower potassium and lower viscosity than the University of Wisconsin solution that has been recently used in liver transplantation. In the present series, we compare the outcome of liver grafts from brain-dead donors preserved in IGL-1cold storage solution, with cold ischemia times (CITs) longer than 8 hours and those less than 8 hours. Two hundred fifty-two liver transplantations performed from January 2014 to December 2016 at Hospital Santa Isabel, Blumenau, Brazil, were retrospectively analyzed. The patients were divided in two groups according to the CIT. Group I patients (N = 155) had less than 8 hours of CIT with a mean age of 54 ± 11.35 years, whereas group II patients (N = 97) had more than 8 hours of CIT with a mean age of 52 ± 12.5 years. There was no difference between the groups related to indication for liver transplantation and donor characteristics. The only difference statically significant on laboratory data was between the levels of aspartate aminotransferase at day 1 after transplantation. On day 7 post-transplantation there was no difference statistically significant between aspartate aminotransferase, alanine aminotransferase, and bilirubin levels between the two groups. Similar 1-year patient survival rates were found in both groups, with 85.88% for group I and 85.75% in group II. The IGL-1 solution has been shown to be safe, effective, and with good results in liver transplantations. Early graft function and 1-year patient survival rates did not differ when grafts preserved for less than 8 hours were compared to those with CIT greater than 8 hours.

Use of Georges Lopez Institute Preservation Solution IGL-1 in Pancreas Transplantation: A Series of 47 Cases.

BACKGROUND: Graft preservation continues to be one of the main pillars of pancreas transplantation (PT). Surgical complications, possibly caused or facilitated by organ damage during preservation, continue to occur more frequently after PT than for any other abdominal organ. During the past few years, the Georges Lopez Institute preservation solution IGL-1 has been introduced with satisfactory results for the perfusion and cold storage of abdominal grafts such as kidney and liver. METHODS: Aspects related to 47 PTs with the use of IGL-1 as the only preservation solution performed from January 2012 to September 2017 at Hospital Santa Isabel, Blumenau, Brazil, were retrospectively analyzed. RESULTS: Considering the 46 transplanted patients (1 patient underwent 2 PTs), graft loss followed by death occurred in 2 patients: 1 due to pancreatic thrombosis, and 1 due to sepsis. In addition, a 3rd patient died with a functioning graft due to sepsis of an infected hematoma. In 1 patient, graft loss occurred due to pancreatic thrombosis and was later retransplanted. One patient presented post-transplantation pancreatitis. The overall survival of patients in 1 month after transplantation was 95.7%, and graft survival in the 1st month was 93.6%. CONCLUSIONS: In all patients transplanted with the use of IGL-1, normalization of pancreatic function occurred early after reperfusion, there was no delayed graft function, and all transplanted patients maintained a non-insulin-dependent status after transplantation. The use of IGL-1 as preservation solution for PT is safe and effective.

Use of IGL-1 preservation solution in liver transplantation.

University of Wisconsin (UW) solution has been known as the standard solution for liver graft preservation. Alternative preservation solutions have been used in liver transplantation, such as histidine-tryptophan-ketoglutarate (HTK) and Celsior solution. Institut Georges Lopez-1 (IGL-1) is a new preservation solution with lower potassium and lower viscosity than UW solution that has recently been used in liver transplant. Data from 178 patients who received transplants from August 2008 to June 2013 at Hospital Santa Isabel, Blumenau, Brazil, were analyzed. All patients received grafts from brain death donors. In November 2011 we started to use IGL-1 as an alternate preservation solution. Therefore, 53 patients using IGL-1 preserved grafts were compared to 125 using HTK solution. The donor age in the HTK group ranged from 11-77 years, with a mean of 43.4 ± 4.8. In the IGL-1 group donor age ranged from 9-62 years, with a mean of 35.8 ± 4.5. Cold ischemia time in the HTK group ranged from 85-1145 minutes, mean 443.5 ± 183.5 minutes. In the IGL-1 group, cold ischemia time ranged from 85-670 minutes, mean 329.3 ± 134.8 minutes. The overall operative mortality rate was 14% (25 patients); in the HTK group, 14.4% (18 patients); and in the IGL-1 group, 13.4% (7 patients). One graft in the HTK group presented with primary non-function (PNF), 0.7%; there were none in the IGL-1 group. In our study, IGL-1 has been shown to be safe to use as a preservation solution for liver transplantation. Early post-transplant graft function was comparable to that observed with HTK solution, although a tendency for lower alanine aminotransferase levels was noticed. IGL-1 has been shown to be safe, cost efficient, and an effective preservation solution.

Analysis of survival after primary liver transplantation: multivariate analysis of 155 cases in a single center.

Liver transplantation is known as a highly complex procedure. Several variables can affect the outcome. The present study is a retrospective multivariate analysis of the outcomes of primary liver transplant recipients from deceased donors. From November 2006 through January 2009, 155 patients received first liver transplants from deceased donors. The data included the following: age of the recipient, gender of the recipient, ABO type, indication for the transplantation, model for end-stage liver disease (MELD) score, operative time, donor age, gender of the donor, cold ischemia time, and quantity of transfused blood products-red blood cells (PRBC), red blood cells recovered during the operation (cell saver), platelets, and fresh frozen plasma. Statistical analysis was done using SPSS 17 software. Cox regression analysis was performed to identify significant variables. ROC (receiver operating characteristic) curve was applied for those significant factors. Among all variables, only PRBC transfusion and MELD score showed statistical significance. For PRBC the increment of death risk was 17.08%, and for MELD score it was 3.83%. Patients that had to use PRBC and higher MELD scores had worse survivals. We concluded that the requirement for red blood cell transfusions and MELD showed the most significant influences on the outcomes of adult liver transplantations from deceased donors.

Prevalence of posttransplantation lymphoproliferative disease in pediatric liver transplant recipients.

OBJECTIVE: The objective of this study was to identify the incidence of posttransplantation lymphoproliferative disease (PTLD) among children within 1 year after liver transplantation. METHODS: This retrospective review analyzed information in medical charts of pediatric (younger than 18 years of age) recipients of liver transplants between September 2000 and December 2007. RESULTS: Seventy-one patients underwent a liver transplantation and 7 (9.85%) developed PTLD. Among this group, 6 children were girls and 1 was a boy. The median age at transplantation was 35.14 months. Indications that led the children to have their transplantation were 1 case of hemangioendothelioma, 1 case of autoimmune hepatic cirrhosis, 1 case of alpha-1-antitrypsin deficiency, and 4 cases of biliary atresia. The most frequent symptoms were splenomegaly, diarrhea, and fever. The median time from the first symptoms to the initial treatment was 9.7 days. The standard treatment was withdrawal of immunosuppression and close observation of tacrolimus levels and liver function tests associated with antiviral drugs and chemotherapy. Four among 7 children died; 3 children recovered. All 3 children who recovered has presented at the transplantation center within 5 days of initiation of symptoms (P = .033896). CONCLUSION: Despite its rarity, when it occurs, PTLD shows a high mortality rate. Therefore, it is necessary to have interdisciplinary work between the medical team that performs the transplantation and those promoting the primary care to diagnose the disease early and treat it effectively.

Results of 132 hepatectomies for living donor liver transplantation: report of one death.

AIMS: Liver transplant is the primary therapy for patients with end-stage liver disease. Its high success rates have lead to a broadening of the indications for liver transplantation, resulting in an increasing shortage of donors. Living donor liver transplantation has become an option to overcome waiting list mortality. We describe our experience with hepatectomy for living donor liver transplantation and report a case of death. METHODS: Patients (n = 132) underwent hepatectomy for living donor liver transplantation from June 2000 through June 2004. A 4-phase preoperative evaluation was performed on all patients, whose ages ranged from 13 to 54 years (mean = 29.7 +/- 8.1 years). Of the 132 patients, 76 patients (57.5%) underwent left lateral segmentectomy, 33 patients (25%) underwent left lobectomy, and 23 patients (16%) underwent right hepatectomy. In 2 other patients (1.5%), a monosegment (segment II) was obtained after left lateral segmentectomy. RESULTS: Twenty patients (15%) experienced a complication, the most common being incisional hernia, pneumonia, and biliary fistulae. On the seventh postoperative day, 1 patient developed a fatal cerebral hemorrhage while recovering from mild liver dysfunction. CONCLUSIONS: Although living donor liver transplantation is generally safe, serious and fatal complications may occur.

Transhepatic biliary catheterization before graft implant in living donor liver transplantation.

AIM: Despite the evolution in surgical technique, the biliary anastomosis remains the technical Achilles' heel of liver transplantation, especially in living donor liver transplantation. Interventional radiology or endoscopic procedures constitute the most common options to treat complications from the biliary anastomosis. We report a novel technique to prevent biliary complications following the transplant. METHODS: During the donor procedure a wire guide was introduced in the severed duct, left or right, in retrograde fashion. The liver surface was then perforated and the wire guide exposed. A 4F catheter was then attached to the wire guide and pulled into the bile duct passing through the end-to-end duct-to-duct anastomosis or hepaticojejunostomy. RESULTS: This technique was performed in six living donor grafts: one right lobe, two left lobes, and three left lateral segments. All patients had no complications from the stent placement, biliary strictures, or leaks. One developed a hepatic artery thrombosis on the posttransplant day 14 with no major biliary complications.

Daclizumab induction therapy associated with tacrolimus-MMF has better outcome compared with tacrolimus-MMF alone in pediatric living donor liver transplantation.

AIMS: Immunosuppression therapy for the control of immunologic rejection is a key aspect in liver transplantation. The objective of this study was to evaluate induction therapy with daclizumab (DAC) in living donor liver transplantation (LDLT) in children. METHODS: We compared 2 different immunosuppression protocols in 30 children undergoing LDLT. The patients were divided into 2 groups: 12 patients received tacrolimus with mycophenolate mofetil (TAC-MMF), and 18 patients received tacrolimus with MMF and DAC induction therapy at days 0 and 14 after LDLT (DAC-TAC-MMF). Both groups were similar with regard to age, sex, weight, and indication for liver transplantation. The incidence of biopsy-proved rejection episodes, posttransplantation lymphoproliferative disease (PTLD), and renal dysfunction were evaluated. Tacrolimus levels at posttransplantation day 14 and at 2 months after transplantation were compared in the 2 groups. RESULTS: Acute rejection episodes were observed in 8 patients in the TAC-MMF group (66%), and none in the DAC-TAC-MMF group (0%; P < .05). Neither PTLD nor renal dysfunction was seen in any patient. Mean Tacrolimus level on posttransplantation day 14 was 10.67 +/- 5.4 ng/mL in the TAC-MMF group and 5.65 +/- 3.6 ng/mL in the DAC-TAC-MMF group (P < .05). After the second month the mean tacrolimus levels were 7.2 +/- 2.9 ng/mL and 6.8 +/- 3.5 ng/mL in the TAC-MMF and DAC-TAC-MMF groups, respectively. (P = NS). CONCLUSION: Induction therapy with DAC is safe and associated with a lower incidence of rejection episodes among children undergoing LDLT.

Results of 60 consecutive hepatectomies for pediatric living donor liver transplantation.

Several technical improvements have been made to increase donor pool for pediatric liver transplantation, including reduced-size grafts, split-liver, and recently living donors. The objective of the present study is to report our single-center experience with 60 hepatectomies for living donor liver transplantation in pediatric recipients between June 2000 and December 2002. Donor workup consisted of a complete history and physical examination followed by laboratory test and liver function tests. Graft size was estimated using computed tomography scan or abdominal ultrasound. Liver biopsy was performed in all donors. Arteriogram was performed to evaluate hepatic arterial anatomy. All donors survived the procedure. Only seven patients experienced complications (10.2%), most of which were short term. We conclude that liver living donation for pediatric population is a safe procedure.

[Normalization of menstrual cycles and pregnancy after liver transplantation]. / Normalização dos ciclos menstruais e gravidez após transplante de fígado.

The objective of the present study is to evaluate the effects of successful liver transplantation on menstrual cycles abnormalities and on reproductive function of women with chronic liver disease. Twelve women with age between 17 and 54 years who underwent liver transplantation were evaluated. The following variables were analyzed: age, etiology of chronic liver disease, pattern of menstrual function and period of amenorrhea before and after transplantation, and occurrence of pregnancy after transplantation. The mean age of patients was 36 +/- 12.6 years. Patients with primary biliary cirrhosis did not have menstrual abnormalities before transplantation. The other patients presented amenorrhea for 3 months to 11 years before the transplantation. Rapid recovery of menstrual function was observed in all patients after the transplantation (3.1 +/- 1.2 months). Two patients became pregnant one and three years after the transplantation. It is concluded from this study that most women who present amenorrhea secondary to chronic liver disease have normal menstrual cycles in approximately three months following liver transplantation and they may become pregnant.

Conversions and complications of laparoscopic treatment of gastroesophageal reflux disease.

BACKGROUND: Although several authors have documented the safety and efficacy of laparoscopic fundoplication, it is important to determine the rate of conversions and complications of this procedure. STUDY DESIGN: We retrospectively reviewed the protocol sheets of 503 consecutive patients with gastroesophageal reflux disease who underwent laparoscopic fundoplication over a period of 5 years. A Nissen-Rosetti procedure was performed in 492 patients (97.8%) and a Toupet procedure in 11 (2.2%). Sixty-four patients were also subjected to a concurrent cholecystectomy, and one patient had a concurrent cervical pharyngoesophageal diverticulectomy with cricopharyngeal myotomy. Thirty-one patients had previous upper abdominal operations. RESULTS: The period of hospitalization varied from 12 hours to 16 days, with an average of 1.2 days. The operation was converted to an open procedure in 10 patients (2%). The main cause of conversion was the presence of adhesions. The most frequent intraoperative complication was pneumothorax. All pneumothoraces occurred in the first 100 patients. Five patients had significant operative bleeding; two of them required laparotomy for bleeding control. Gastric ulcer was diagnosed in six patients. One alcoholic patient died of acute pancreatitis. Other major complications were two intraabdominal abscesses, one esophageal perforation, one sepsis from gastric perforation, one hemorrhagic shock, and one gastric obstruction from fundoplication herniation. CONCLUSIONS: Conversions and complications of laparoscopic fundoplication are low and decrease significantly with the surgeon experience, but severe and lethal complications may occur.

Isolated tuberculosis of the pancreas after orthotopic liver transplantation.

A patient presented with intermittent high fever, upper abdominal pain, and loss of appetite 9 months after an orthotopic liver transplantation. Computed tomography showed a large mass in the pancreas that was confirmed at laparotomy. Pathological examination of the pancreatic biopsy specimen showed several chronic granulomatous lesions with caseating necrosis. Two and one half months after beginning antituberculous treatment, there was an important reduction of the pancreatic mass.

Objetivo. Determinar o custo do transplante hepático no Hospital de Clínicas da Universidade Federal do Paraná. Método. Os dados do prontuário de 24 pacientes submetidos a 25 transplantes hepáticos foram avaliados do dia da internaçao para o transplante hepático até a data da alta hospitalar ou óbito para determinar o número de dias de internaçao, o local de internaçao, a quantidade de material e medicamentos usados, os exames complementares e procedimentos realizados. Honorários médicos nao foram incluídos no estudo. Resultados. A idade dos pacientes variou de 6 a 56 anos, tendo seis deles menos que 14 anos de idade. Cinco pacientes foram a óbito durante a internaçao hospitalar. Retransplante foi realizado em somente um paciente. O custo médio da retirada do fígado do doador foi de US$ 2,783.19. O custo total do transplante hepático variou amplamente entre os pacientes, na dependência de ocorrência de complicaçoes pós-operatórias, do número de dias de internaçao hospitalar e da quantidade de transfusao de hemoderivados. O custo total variou de US$ 6,359.84 a US$ 75,434.18, com média de US$ 21,505.53. O item mais caro do transplante hepático foi o custo com a hemoterapia, seguido do custo com medicamentos e diária hospitalar. Conclusao. O custo do transplante hepático varia muito entre os pacientes e pode ser realizado no Brasil a um custo inferior ao relatado nos Estados Unidos e na Europa.

[Cost of liver transplantation at the Clinical Hospital of the University of Parana, Brazil]. / Custo do transplante hepático no Hospital de Clínicas da Universidade Federal do Paraná.

PURPOSE: To determine the cost of liver transplantation at the Clinical Hospital of the Federal University of Parana. METHODS: The data of 24 patients subjected to 25 liver transplantations were evaluated from the day of hospital admission until the day of discharge to determine the length of hospitalization, quantity of material and medications used, and exams and procedures performed. Professional fees were not included in the study. RESULTS: The age of the patients varied from 6 to 56 years. Six patients were younger than 14 years of age. Five patients died during hospitalization. Retransplantation was performed in only one patient. The average cost for liver procurement was US$ 2,783.19. The total cost of the liver transplantation varied, depending on the occurrence of complications, length of hospitalization and the amount of blood products transfused. The total cost varied from US$ 6,359.84 to US$ 75,434.18, with an average of US$ 21,505.53. The most expensive item of the liver transplantation was blood products transfused, followed by medications, and intensive care and room charges. CONCLUSIONS: The cost of liver transplantation varies among the patients and may be performed in Brazil at a cost less than that reported in the United States and Europe.

Motility of Oddi's sphincter: recent developments and clinical applications.

BACKGROUND: In recent years, applications of electromyographic, cineradiographic, scintilographic, and endoscopic manometric techniques have improved our knowledge of normal and abnormal motility of Oddi's sphincter. This sphincter coordinates the time and rate of secretion of about 3 liters of bile and pancreatic juice into the duodenum daily. METHODS: Oddi's sphincter may be evaluated by endoscopic manometry, ultrasound, dynamic hepatobiliary scintigraphy, and laboratory tests. Endoscopic manometry is the best method for evaluating the function Oddi's sphincter. RESULTS: The basal pressure of Oddi's sphincter is usually 5 to 15 mm Hg greater than the bile and pancreatic duct pressures. Phasic contractions of 50 to 150 mm Hg in amplitude and 3 to 8 contractions per minute in frequency are superimposed on the basal pressure. A small percentage of patients with gastrointestinal symptoms after cholecystectomy has sphincter of Oddi dysfunction, which may have structural abnormality (papillary stenosis) or functional abnormality (Oddi's sphincter dyskinesia). CONCLUSIONS: Elevated basal pressure ( > 40 mm Hg) is the most important manometric finding of Oddi's sphincter dysfunction. Endoscopic sphincterotomy is the treatment of choice for patients with Oddi's sphincter dysfunction and elevated basal sphincter pressure.

Extrapyramidal disorder secondary to cytomegalovirus infection and toxoplasmosis after liver transplantation.

A boy underwent liver transplantation for postnecrotic cirrhosis secondary to Wilson's disease. The patient had no neurological clinical manifestations prior to the transplantation. The patient developed dysarthria, dysphagia, spasticity, rigidity, and intention and resting tremor of all extremities. Cranial computerized tomography revealed hypodensity of the thalamus, basal ganglia and external capsule. Anti-cytomegalovirus IgM became positive. At autopsy, there were severe pathological changes at the thalamus and basal ganglia.

Doaçäo de órgäos: opiniäo e conhecimento de médicos intensivistas da cidade de Curitiba / Organ donation: opinion and knowledge of intensive care unit physicians in the city of Curitiba

Com o objetivo de avaliar as opiniöes e conhecimentos de médicos intensivistas sobre doaçäo de órgäos, todos os intensivistas dos 13 hospitais de Curitiba com unidade de terapia intensiva de adulto participaram do estudo. De 81 intensivistas entrevistados, 75 (92,6 por cento) responderam o questionário. Todos responderam que säo favoráveis à doaçäo de órgäos, 74 (98,7 por cento) doariam seus próprios órgäos e 72 (96 por cento) autorizariam a doaçäo de órgäos de um membro da sua família. Sessenta e três (84 por cento) intensivistas näo conheciam ou näo souberam explicar a legislaçäo atual sobre doaçäo de órgäos. Quarenta e um (54,7 por cento) responderam errado ou näo sabiam os critérios médicos e legais para doaçäo de órgäos. Cinco (6,7 por cento) desconheciam a necessidade do doador ter morte encefálica, três (4 por cento) acreditavam que o doador deveria ter morte cardíaca para ser doador e 44 (58,7 por cento) näo souberam explicar o que é morte encefálica. A maioria desconhecia a sobrevida atual dos pacientes submetidos a transplante dos vários órgäos. Conclui-se deste estudo que quase todos os médicos intensivistas de Curitiba säo favoráveis a doaçäo de órgäos e estäo dispostos a participar ativamente na obtençäo de consentimento de familiares para doaçäo. O conhecimento básico sobre a legislaçäo brasileira e os vários aspectos médicos do transplante de órgäos é insatisfatório.

[Acute pancreatitis caused by varicella-zoster virus after liver transplantation]. / Pancréatite aiguë par le virus varicella-zoster après une transplantation du foie.

Twenty-six days after liver transplantation for primary biliary cirrhosis, a 52 year-old patient was rehospitalized for viral infection. The clinical features were fatigue, anorexia and vomiting. On physical examination, vesicular skin lesions involving the left 8 th intercostal space were suggestive of herpes-zoster infection. The following day the patient was extremely tired and dyspnoeic. The abdomen was distended with moderate abdominal epigastric pain. The clinical picture worsened rapidly and the patient died a few hours later. Autopsy revealed acute haemorrhagic necrosis of the pancreas due to herpes-zoster virus.

[Organ donation: opinion and knowledge of intensive care unit physicians in the city of Curitiba]. / Doação de órgãos: opinião e conhecimento de médicos intensivistas da cidade de Curitiba.

Our objective is to determine the opinions and knowledge of intensive care unit physicians toward organ donation. All physicians working in all 13 hospitals of Curitiba with intensive care unit for adults participated of the study. Of a total of 81 physicians, 75 (92.6%) answered the questionnaire. All physicians were favorable to organ donation, 74 (97.7%) were willing to donate their own organ and 72 (96%) to donate the organs of their relatives. Sixty-three (84%) did not know the present law on organ donation. Forty-one (54.7%) did not know the medical and legal criteria for organ donation. Five (6.7%) did not know that the patient had to have brain death in order to donate an organ, 3 (4%) thought that the patient had to have heart death in order to donate an organ, and 44 (58.7%) did not know how to explain brain death. Most physicians did not know the patient survival after transplantation of several organs. It is concluded that almost all intensive care unit physicians in Curitiba are favorable to organ donation and are willing to participate actively in obtaining consent of family members for donation. The basic knowledge of Brazilian law and several medical subjects on organ transplantation is unsatisfactory.

Electromyographic activity of gastrointestinal tract of patient with short-bowel syndrome.

Electromyographic recordings were obtained from a patient with short-bowel syndrome. Eight recording sessions were performed in almost 3 mo, during both fasting and fed states. Slow waves were always present, and their frequencies were similar during both states. Phase III of the migrating motor complex (MMC) was not identified in any of the four recordings performed in the 1st mo after the operation. Afterward, phase III was observed in three of four recordings. Ingestion of milk caused substitution of the MMC by the fed pattern in all eight recordings. We conclude that extensive small-bowel resection causes temporary disappearance of phase III of the MMC. A change from a fasting to a fed pattern after food ingestion is normal.
