RESUMO

Mujer de 69 años no fumadora, que acude a urgencias por dolor abdominal, intolerancia oral y síndrome constitucional. Se solicita TAC identificando adenopatías axilares, mediastínicas y mesentéricas, derrame pleural bilateral, obstrucción ureteral derecha y lesión ósea blástica en D12 compatible con metástasis, sin objetivar tumor primario. La evolución clínica fue desfavorable, precisando nuevo TAC, observándose cambio de calibre en íleon terminal sin visualizar causa obstructiva. Se decide intervención quirúrgica, objetivándose dilatación intestinal, engrosamiento mesentérico, con obstrucción ileal adyacente a válvula íleocecal, secundaria a tumoración mesentérica retroperitoneal, realizándose hemicolectomía derecha. El diagnóstico anatomopatológico fue de metástasis de carcinoma pulmonar tipo sarcomatoide en su variante pleomórfica, hallazgo excepcional por lo infrecuente de la diseminación mesentérica de estos tumores. Había afectación de 15 ganglios mesentéricos, positividad en la citología del derrame pleural y de ganglios axilares. La paciente presentaba una diseminación peritoneal. Dado el mal pronóstico, se decidió quimioterapia paliativa (Carboplatino-Paclitaxel) (AU)


A 69 year-old women, non-smoker, who came to the emergency for abdominal pain, oral intolerance and constitutional syndrome. A CT scan identified axillary, mediastinal and mesenteric lymphadenopathy, bilateral pleural effusion, right ureteral obstruction and blast bone metastasis lesion in D12, without observing a primary tumor. The clinical course was unfavorable, requiring new CT scan, where a change in caliber in terminal ileum was observed without an obstructive cause. Surgical intervention was proposed, intestinal dilation and mesenteric thickening were found, with ileal obstruction adjacent to the ileocecal valve, secondary to a retroperitoneal mesenteric tumor, a right hemicolectomy was performed. The pathological diagnosis was pleomorphic sarcomatoid lung carcinoma metastasis. This finding is exceptional due to the infrequency of the mesenteric dissemination of these tumors. There were involvement of 15 mesenteric lymph nodes, positive cytology of the pleural effusion and axillary lymph nodes. Due to the bad prognosis, palliative chemotherapy (Carboplatin-Paclitaxel) was proposed (AU)

RESUMO

Abdominal wall transplant is developed in the context of intestinal and multivisceral transplant, in which it is often impossible to perform a primary wall closure. Despite the fact that abdominal wall closure is not as consequential in liver transplant, there are circumstances in which it might determine the success of the liver graft, especially in situations that compromise the abdominal cavity and facilitate an abdominal compartment syndrome. CASE 1: A 14-year-old girl suffering from cryptogenic cirrhosis with severe portal hypertension that causes ascites and severe malnutrition. Uneventful liver transplant, with a graft procured from a 14-year-old donor. At the time of wall closure it was decided to implant a nonvascularized fascia graft to supplement the right side of the transverse incision, with a 17 x 7 cm defect. This required reintervention after 4 months for biliary stricture. At that point, the wall graft was almost completely integrated into the native tissue. CASE 2: A 63-year-old man, transplanted for hepatitis C virus+ hepatocellular carcinoma+ nonocclusive portal thrombosis. Thirty-six hours after transplant the patient developed portal thrombosis. Thrombectomy and closure with biological mesh were performed. After 24 hours he was reoperated on for abdominal compartment syndrome and temporary closure with a Bogotá bag. Six days later he underwent omentectomy, intestinal decompression, and left components separation, identifying a 25 x 20 cm defect. For definitive closure, a nonvascularized fascia graft procured from a different donor was used, accomplishing a reduction in intra-abdominal pressure. Nonvascularized fascia transplantation is an interesting alternative in liver transplant recipients with abdominal wall closure difficulties.

RESUMO

BACKGROUND: The prevalence of obesity has increased dramatically, even in the population awaiting a liver transplantation. Despite their associated complications, we cannot consider morbid obesity any longer as an absolute contraindication to liver transplantation. Dietary approaches alone are usually completely ineffective. Bariatric surgery is the gold-standard treatment for morbid obesity and can be performed before, during, or after transplantation. MATERIALS AND METHODS: At our Liver Transplantation Unit, a single surgeon performed a sleeve gastrectomy in 8 patients with liver cirrhosis due to nonalcoholic steatohepatitis, alcohol, or HCV. The Child score was A in 6 patients and B in the remaining 2 patients. Two of our patients had portal hypertension with mild esophageal varices. The procedure was performed laparoscopically in 7 cases (87.5%); in the other case, it was performed by open approach due to portal hypertension and according to patient preferences. RESULTS: Patients showed no postoperative morbidity or mortality. The mean postoperative body mass index of our patients was 37.4, 33.3, and 30.3 kg/m2 at 3, 6, and 12 months after surgery, respectively. The mean percentage excess weight loss of our patients was 42.9%, 62.2%, and 76.3% at 3, 6, and 12 months. Two of the patients have already undergone a successful liver transplant. CONCLUSION: Bariatric surgery in selected patients with compensated cirrhosis and without significative portal hypertension is reasonable. There are not clear guidelines on the use of bariatric surgery in patients with cirrhosis. In our experience, the sleeve gastrectomy is safe and effective in the treatment of patients with compensated cirrhosis; in a short time, the sleeve gastrectomy can improve candidacy in morbidly obese patients awaiting transplantation.

RESUMO

We examined intraepithelial lymphocytes (IELs) in 213 ileal biopsies from 16 bowel grafts and compared them with 32 biopsies from native intestines. During the first year posttransplantation, grafts exhibited low levels of IELs (percentage of CD103(+) cells) principally due to reduced CD3(+) CD8(+) cells, while CD103(+) CD3(-) cell numbers became significantly higher. Changes in IEL subsets did not correlate with histology results, isolated intestine, or multivisceral transplants, but CD3(-) IELs were significantly higher in patients receiving corticosteroids. Compared with controls, more CD3(-) IELs of the grafts expressed CD56, NKp44, interleukin (IL)-23 receptor, retinoid-related orphan receptor gamma t (RORγt), and CCR6. No difference was observed in granzyme B, and CD3(-) CD127(+) cells were more abundant in native intestines. Ex vivo, and after in vitro activation, CD3(-) IELs in grafts produced significantly more interferon (IFN)-γ and IL-22, and a double IFNγ(+) IL-22(+) population was observed. Epithelial cell-depleted grafts IELs were cytotoxic, whereas this was not observed in controls. In conclusion, different from native intestines, a CD3(-) IEL subset predominates in grafts, showing features of natural killer cells and intraepithelial ILC1 (CD56(+) , NKp44(+) , CCR6(+) , CD127(-) , cytotoxicity, and IFNγ secretion), ILC3 (CD56(+) , NKp44(+) , IL-23R(+) , CCR6(+) , RORγt(+) , and IL-22 secretion), and intermediate ILC1-ILC3 phenotypes (IFNγ(+) IL-22(+) ). Viability of intestinal grafts may depend on the balance among proinflammatory and homeostatic roles of ILC subsets.

RESUMO

BACKGROUND AND AIMS: Combination of hepatitis B immunoglobulin (HBIG) and a nucleos(t)ide analog (NA) is considered the standard of care for prophylaxis of hepatitis B virus (HBV) recurrence after liver transplantation (LT). However, use of lifelong HBIG has significant limitations. We evaluated the efficacy and safety of entecavir (ETV) or tenofovir disoproxil fumarate (TDF) after withdrawal of HBIG in patients who had been under HBIG-regimen prophylaxis post LT. METHODS: Patients at low risk of recurrence were eligible for HBIG discontinuation (fulminant HBV hepatitis, co-infection with hepatitis D virus, and hepatitis B e antigen-negative cirrhotic patients with HBV DNA levels <300 copies/mL). All patients had received HBIG, with or without NA, for at least 12 months after LT. After HBIG discontinuation, they continued with ETV or TDF monotherapy. Patients were followed up with HBV serum markers and evaluation of renal function. RESULTS: Between September 2011 and June 2014, 58 liver transplant recipients were converted to TDF (31, 53%) or ETV (27, 47%). Mean follow-up after conversion was 28 ± 5 months (range 13-36 months). Five patients (8.6%) developed detectable hepatitis B surface antigen at 7, 9, 13, 15, and 22 months after HBIG discontinuation. However, in every case seroconversion was transitory, serum HBV DNA was undetectable, with no clinical manifestations of HBV recurrence. No adverse effects were observed or dose reductions required associated with ETV or TDF. CONCLUSIONS: Maintenance therapy with newer NAs, after discontinuation of HBIG prophylaxis, was safe and effective, with a low rate of serological recurrence and no evident clinical, biochemical, or virological consequences.

RESUMO

Lesions produced in the graft mucosa due to harvesting, storage, and implantation must be graduated to assess the subsequent protocolized biopsy specimens. The aim is to identify type and intensity of graft mucosal lesions observed immediately after implantation. Congestion, hemorrhage, microthrombi, neutrophilic infiltrates, shortening of villi, epithelial detachment, erosion, and crypt loss were separately evaluated by two pathologists in mucosal biopsy specimens from 13 grafts. Each change was assessed as normal, mild, moderate, or severe and by splintering the summation of points a global score was designed. Cold ischemia time was registered. Correlation between the pathologists' evaluations and between final preservation injury degree and cold ischemia time was determined using the "index of correlation rho (ρ)" (Spearman's test). The same changes were assessed in 19 biopsy specimens from day 2 to day 6 (3.6 ± 1.1) to determine their evolution. Congestion was found in 7 biopsy specimens, microthrombi in 2, hemorrhage in 4, neutrophils in 6, villous atrophy in 8, epithelial detachment in 9, erosions in 2 and/or crypt loss in 2. The maximum degree of preservation injury was expressed as intense congestion and hemorrhage associated with epithelial detachment and villous atrophy. The global preservation score was grade 3 in 2 cases, grade 2 in 5, grade 1 in 2, and grade 0 in 4. There was positive correlation (ρ = 0.915) in the evaluation between pathologists (P < .01), total agreement in 9 biopsy specimens, and partial agreement (only 1 point disagreement) in 4. Mean cold ischemia time was 327 ± 101 min. (135-480). There was positive correlation (ρ = 0.694) between preservation score and cold ischemia time (P < .01). In the follow-up biopsy procedures, histological injury decreased by at least one grade in every case. Additionally, karyorrhexis was observed in 3 grafts and very occasional apoptosis in 2 others. This scale achieves good reproducibility and allows graduate preservation injury in intestinal transplantation.

RESUMO

BACKGROUND: Sexual and reproductive abnormalities affect up to 50% patients with terminal liver failure. However, these functions recover quickly after orthotopic liver transplantation (OLT). Thus, 80%-90% of OLT women of childbearing age recover menstruation within a few months after transplantation. The aim of our study was to analyze the impact of pregnancy among liver transplant recipients at our center, as well as to analyze the effects of immunosuppression on the fetus. METHODS: From April 1986 to April 2011, we performed 1500 OLT in 1341 recipients. Among these recipients, 18 patients (1.2%) become pregnant during the follow-up. RESULTS: The most frequent causes of terminal liver failure were as follows: chronic parenchymal disease (n = 9; 50%), cholestatic disease (n = 3; 16.6%), acute liver failure (n = 5; 27.7%), and metabolic disease (n = 1; 5.5%) The average recipient age at the beginning of pregnancy was 21.2 (±7.3) years. Sixteen patients (88%) became pregnant beyond a year after OLT. The 30 pregnancies in our study resulted in the following: newborns alive (NBA; n = 20; 66.6%) abortions (n = 8; 26.6%) or fetal deaths (n = 2; 6%). The most common immunosuppressant used during pregnancy was tacrolimus (75%) followed by cyclosporine (25%). There were no maternal deaths during pregnancy or the postpartum period. DISCUSSION: We did not observe significant differences between immunosuppression type and maternal complications, pregnancy duration, and childbirth type. Although pregnancy is potential risk, the literature and our results suggest that at a year or more after OLT it usually is safe and successful.

RESUMO

INTRODUCTION: Everolimus is a potent immunosuppressant with several advantages over calcineurin inhibitors, such as good tolerance, preventive effects on cardiovascular morbidity, and mortality and cancer prevention as it inhibits cell proliferation. PATIENTS AND METHODS: Between April 1986 and December 2010, we performed 1500 liver transplants (OLT) in 1341 recipients, including 57 patients who were prescribed everolimus 24 (42.1%) as monotherapy and 33 (57.9%) as treatments combined with other immunosuppressants. We performed a retrospective analysis of our experience with conversion to everolimus in OLT recipients. RESULTS: The 43 men and 14 women had a mean overall age at transplantation of 59.1 ± 10 years. The most frequent indication for OLT was hepatocellular carcinoma (HCC; 53.8%). Everolimus was introduced to prevent HCC recurrence (53%), development of de novo tumors (33%), address renal dysfunction (7%), or overcome side effects of other immunosuppressants (7%). We observed a significant improvement in renal function using the estimated glomerular filtration rate (Crockcroft-Gault formula) from 68.5 mL/min before to 74.5 mL/min after switching to everolimus. The 72% of recipients who developed ≥1 adverse event, most frequently showed hyperlipidemia (34.4%). CONCLUSION: Both monotherapy and combined everolimus regimens were well-tolerated immunosuppressive regimens in liver transplant recipients with recurrent or de novo malignancies. Everolimus improved renal function. The most common side effects were hyperlipidemia, edema, and mouth ulcerations, which were well controlled with anti-lipidemic agents or decreased everolimus dosages.

RESUMO

Una de las características singulares de la enfermedad de Parkinson (EP) es la gran variabilidad clínica en relación con el tratamiento que puede acontecer en un mismo paciente. Esto sucede tanto con el tratamiento específico para la EP como con otra serie de fármacos que pueden empeorar la función motora. Por esta razón, el manejo perioperatorio de la EP requiere experiencia y sobre todo una planificación adecuada. En este artículo se revisan las peculiaridades de la EP y su tratamiento, y se plantea una estrategia para el perioperatorio de estos pacientes (AU)


One of the particular characteristics of Parkinson's disease (PD) is the wide clinical variation as regards the treatment that can be found in the same patient. This occurs with specific treatment for PD, as well as with other drug groups that can make motor function worse. For this reason, the perioperative management of PD requires experience and above all appropriate planning. In this article, the peculiarities of PD and its treatment are reviewed, and a strategy is set out for the perioperative management of these patients (AU)

RESUMO

INTRODUCTION: Total mesorectal excision (TME) of the rectum has been advocated as the gold standard surgical treatment of middle and lower third rectal cancer. Laparoscopy has gained acceptance among surgeons in the treatment of colon malignancies, while scepticism exists about laparoscopic TME in terms of safety and its oncological adequacy. OBJECTIVE: To evaluate the impact of laparoscopic TME on surgical and oncological outcome in a group of consecutive unselected patients. METHODS: One hundred and thirty-two patients with middle or inferior rectal cancer were admitted to our unit and underwent TME from December 1998 to February 2008. Eighty-nine patients were approached with laparoscopy. Patients staged cT3/4 cTxN+ or uTxN+ were submitted to neoadjuvant treatment. Postoperative complications and oncological outcomes were registered. RESULTS: In the laparoscopic group 80 anterior resections (including 4 intersphincteric resections and manual colo- anal anastomosis) and 9 abdominal-perineal resections were performed. 33.3% of patients were enrolled in "long-course" neoadjuvant chemo-radiotherapy (partial and complete response rates 88.2% and 11.8%, respectively). Protective lateral ileostomy was performed in 72% of patients. Mean operative time was 254.3+/-38.3 min and mean blood loss was 215+/-180 ml. Conversion rate was 12.7%. Morbidity rate was 39.3% without mortality. The rate of anastomotic leaks was 13.48%, reoperation rate 13.48%, recovery rate 3.1+/-1.4 days and hospital stay 10.4+/-4.6 days. Concerning adequacy of oncologic resection, mean distance of the tumour from the anal verge was 4.3+/-2.2 cm. Nodal sampling of 12.4+/-4.8 were obtained. Six patients (6/89, 6.74%) had a R1 margin: 3 distal and 3 circumferential. Median follow-up was 29 months and local recurrence rate was 5.79%. Four-year cumulative overall survival was 78% and disease-free survival was 63% (Kaplan-Meier method). CONCLUSIONS: Laparoscopic approach for rectal tumour is a technically demanding procedure, but it is oncologically safe (AU)

RESUMO

BACKGROUND/AIMS: Bacterial infections (BI) are frequent after intestinal transplantation (ITx). Bacteremia, intraabdominal and respiratory infections are the leading forms. The objective of this study is to analyze the occurrence, determinants and outcome of BI. METHODOLOGY: One hundred and twenty-four patients with ITx (39 isolated, 33 liver-intestine, 63 multivisceral). Only major BI were considered, including bacteremia, pneumonia, intraabdominal infections, severe wound infections. RESULTS: BI occurred in 92.7% of patients during follow-up, with an average of 2.9 episodes per patient. Bacteremia was the commonest picture (1.7 per patient). More than 80% of patients had a BI before the end of the second month. Multivariate analysis showed that the presence of BI was higher during the first 2 months after Itx in patients hospitalized before Tx [p=0.029, odds ratio (OR) 5.4] and during months 3 to 6 in those treated with Zenapax (p=0.003, OR 6.2). Occurrence of BI was increased with mycophenolate mofetil treatment (p=0.045 OR 4.2). Intraabdominal infection was more frequent when reTx was needed (p=0.0178 OR 15.2), admission before Tx (p=0.034 OR 2.7), IS with MMF (p=0.004 OR 6.2) and Zenapax (p=0.026 OR 3.6). BI was the direct cause of death in 17.8% of patients, and it was present in 76.2% of patients that died. An infectious episode during the first month, a clinically manifested abdominal infection and a positive intraabdominal culture were determinants of shorter patient survival. CONCLUSIONS: BI continue to be a frequent and dreadful complication after ITx. Pretransplant patient condition, IS used and postoperative complications are crucial on BI onset and outcome.

RESUMO

INTRODUCTION: Portal vein thrombosis (PVT), which had been considered an absolute contraindication to orthotopic liver transplantation (OLT), is currently considered a risk factor that increases morbi-mortality. The objective of this study was to compare OLT outcomes in patients with vs without PVT. MATERIALS AND METHODS: Between April 1986 and December 2003, a sample of 83 patients with PVT was compared with another sample of 83 patients without PVT among 962 OLT performed in our department. RESULTS: Both groups were homogeneous in terms of epidemiological variables, surgical technique, immunosuppression, and donor-related variables. There were no differences with respect to graft function during the first week following surgery. Surgical time and anhepatic phase duration was longer in the PVT group, albeit the differences were not significant. PVT patients also required more transfusions; a strong statistical association was observed with respect to blood (P = .12) and plasma (P = .11) transfusions and statistically significant differences regarding platelet transfusions (P = .02). Time on mechanical ventilation and the length of stay in the ICU were longer but not significant among PVT patients. The only statistically significant difference was the incidence of portal rethrombosis (P = .02). With respect to mean and global patient and graft actuarial survivals after 1, 3, 5, and 10 years, we have observed no significant intergroup differences, although both patient (P = .48; NS) and graft (P = .96, NS) survivals were lower among PVT cases. CONCLUSIONS: PVT should not only cease to be considered a contraindication for OLT, but there were no significant differences between the outcomes despite this finding.

RESUMO

Hepatitis B virus (HBV) recurrence and de novo HBV infection are frequent events in liver transplantation recipients. Treatment with lamivudine is initially efficient in both infections but the incidence of lamivudine-resistant HBV emergence increases over time. Adefovir appears to be promising in post-liver transplantation patients with recurrent HBV infection and lamivudine-resistant HBV. This study analyzed adefovir treatment in 42 post-liver transplantation patients who developed recurrent HBV or de novo HBV infection with lamivudine-resistant HBV (54.8% HCV-coinfected). Patients received 10 mg of oral adefovir once daily for a mean period of time of 21.5 months (range from 12 to 31 months). In 62.9% of patients, ALT levels decreased significantly. Serum HBV-DNA was undetectable in 64% of the cases. Twenty percent of patients lost HBeAg marker and 13.3% of them developed anti-HBe. In 9.5% of recipients, HBsAg became negative. There was no significant change in serum creatinine levels. In only one patient was worsening of the renal function detected, making dose adjustment necessary. No other side effects were reported. Our results confirm the efficacy and safety of adefovir treatment in post-liver transplantation patients with lamivudine-resistant HBV, neither were adefovir-resistant mutations identified in patients after 21 months of therapy, nor were there adverse events, especially renal toxicity.

RESUMO

INTRODUCTION: Lung tumors have been related to tobacco and alcohol. The incidence increases after orthotopic liver transplantation (OLT) especially when it is performed because of alcoholic cirrhosis. PATIENTS AND METHODS: We analyzed the incidence and risk factors for de novo lung tumors among 701 patients who underwent OLT between April 1986 and July 2004, after exclusion of pediatric recipients and adults who died within 2 months after OLT. RESULTS: The incidence of de novo lung tumors was 15 patients (2.1%), including 12 (4.3%) who underwent OLT for alcoholic cirrhosis and 3 (0.7%) for nonalcoholic diseases. There were 14 men and 1 woman of mean age at OLT of 50.8 +/- 9.6 years. Mean time from OLT to lung tumor was 83 +/- 43 months (range, 10-184 months). Thirteen patients (86.6%) were heavy smokers before OLT and 8 (61.5%) continued after OLT; 12 patients (80%) were heavy drinkers before OLT. Ten patients were immunosuppressed with CyA and 5 with tacrolimus. Acute rejection episodes before tumor diagnosis occurred in 6 patients (40%). Two patients underwent thoracotomy, but only one was resected. The remaining 13 patients were unresectable because of locally advanced tumor or metastatic disease. Two unresectable patients received palliative chemotherapy. All patients died with a mean survival from tumor diagnosis, of 5.3 months (range, 3 days to 33 months). CONCLUSION: A significantly higher incidence of lung tumors was observed among patients who underwent OLT for alcoholic cirrhosis, usually diagnosed in advanced stages of poor prognosis and low survival.

RESUMO

HYPOTHESIS: Combined liver-kidney transplantation is safe (low morbidity and acceptable mortality) and effective in patients with end-stage liver disease. Although refinements in surgical technique have resulted in better patient and allograft outcomes, the negative impact of renal insufficiency on survival in patients undergoing liver transplantation has been widely reported, although some aspects are controversial. DESIGN: Analysis of the clinical characteristics and outcome in the management of patients undergoing combined liver-kidney transplantation. The end points were operative mortality, morbidity, and long-term survival. SETTING: University Hospital 12 de Octubre. PATIENTS: Between May 1986 and December 2001, 820 liver transplantations were performed. There were 16 cases (1.96%) of combined liver-kidney transplantations, which represent the sample of this study. RESULTS: Mean +/- SD follow-up of 42.2 +/- 29 months: 6 patients died (37.5% mortality rate). There were 4 (25%) hospital deaths within 6 months following surgery and 2 after 6 months (4 sepsis, 1 refractory heart failure, and 1 recurrent hepatitis C virus disease). Univariate analysis related to mortality included age, sex, etiology, preoperative creatinine level, United Network for Organ Sharing status, Child-Pugh score, type of hepatectomy (piggyback), intraoperative blood product administration, and the presence of postoperative complications. The only 2 significant factors were the presence of postoperative complications (P = .01) and the United Network for Organ Sharing status (P = .02). Crude survival rate was 62.5%. Actuarial survival rates were 80%, 71%, and 60% at 1, 3, and 5 years, respectively. CONCLUSION: Because end-stage renal disease is not a formal contraindication for liver transplantation, a combined liver-kidney transplantation for adults with end-stage renal disease can be done safely and effectively.

RESUMO

Chronic intestinal pseudo-obstruction (CIPO) in children may be life-threatening due to the complications of parenteral nutrition (PN) or catheter-related sepsis. Multivisceral transplantation (MVTx) is a lifesaving option but limited experience is available. We report our experience with MVTx in pediatric CIPO patients. Sixteen children with CIPO underwent MVTx at median age of 4 years. Indications for MVTx were liver failure (n = 10), loss of venous access (n = 3), or sepsis (n = 3). Modified MVTx without the liver was performed in six patients. Induction immunosuppression included tacrolimus, steroid with adjunctive agent in period I (April 1996 to December 2000), namely, OKT3 (n = 1), mycophenolate mofetil (n = 4), or daclizumab (n = 2); and in period II (January 2001 to present), Campath 1H (n = 4) or daclizumab (n = 5). The grade of rejection was severe in 12.5% and mild to moderate in 87.5% of cases. Isolated rejection of the transplanted stomach or pancreas was not diagnosed during clinical course or on autopsy. Actuarial patient survival for 1 year/2 years for period, I and II were 57.1%/42.9% and 88.9%/77.8%. None of the long-term survivors is on PN and all tolerate enteral feedings. Pancreatic enzyme supplementation or insulin therapy is not needed in survivors. Gastric emptying was substantially affected in one case. Bladder function did not improve in those with urinary retention problems. MVTx for CIPO offers a lifesaving option with excellent function of the transplanted pancreas and stomach among survivors.

RESUMO

BACKGROUND/AIMS: In order to establish a rational strategy for organ distribution and optimal patient management, we postulate it is mandatory not only to understand the pathophysiology of failing grafts but also to better recognize the baseline clinical characteristics of the recipients shortly before receiving a second liver allograft. METHODOLOGY: Between March 1986 and December 1997, 1061 patients underwent 1087 orthotopic liver transplantation at three Hospitals in Madrid (122 retransplants). RESULTS: Mean follow-up was 36 months (range, 1-90), 40.6% of the recipients were alive and survival at 1, 3 and 5 years was 62%, 53%, and 46%. Almost 50% of the recipients were UNOS 1 before retransplantation. In comparison to p-OLT (15% UNOS 1), it is clearly shown that the retransplants have been performed in the sickest patients with more adverse prognostic indicators (higher AST, bilirubin, creatinine serum levels, higher Child-Pugh score, higher rate of ascites and lower serum levels of albumin and prothrombin activity). CONCLUSIONS: Liver retransplantation is acceptable and significant differences in recipients' baseline characteristics suggest an impact on lower survival.
