ABSTRACT

The split liver technique enables transplanting 2 recipients with one single graft (typically an adult-child pair). It facilitates small recipients' access to liver transplantation and reduces mortality on the waiting list. However, splitting is technically demanding and may increase peri- and postoperative complications. To be able to obtain comparable outcomes to a full graft liver transplantation, careful donor-recipients selection, experienced surgeons, and logistic planning are paramount. The video shows an in situ split liver procedure from a 32-year-old brain stem death donor to generate a left lateral sector for a child and a right extended graft for an adult recipient.

ABSTRACT

BACKGROUND AND AIM: reduction in calcineurin inhibitor levels is considered crucial to decrease the incidence of kidney dysfunction in liver transplant (LT) recipients. The aim of this study was to evaluate the safety and impact of everolimus plus reduced tacrolimus (EVR + rTAC) vs. mycophenolate mofetil plus tacrolimus (MMF + TAC) on kidney function in LT recipients from Spain. METHODS: the REDUCE study was a 52-week, multicenter, randomized, controlled, open-label, phase 3b study in de novo LT recipients. Eligible patients were randomized (1:1) 28 days post-transplantation to receive EVR + rTAC (TAC levels ≤ 5 ng/mL) or to continue with MMF + TAC (TAC levels = 6-10 ng/mL). Mean estimated glomerular filtration rate (eGFR), clinical benefit in renal function, and safety were evaluated. RESULTS: in the EVR + rTAC group (n = 105), eGFR increased from randomization to week 52 (82.2 [28.5] mL/min/1.73 m2 to 86.1 [27.9] mL/min/1.73 m2) whereas it decreased in the MMF + TAC (n = 106) group (88.4 [34.3] mL/min/1.73 m2 to 83.2 [25.2] mL/min/1.73 m2), with significant (p < 0.05) differences in eGFR throughout the study. However, both groups had a similar clinical benefit regarding renal function (improvement in 18.6 % vs. 19.1 %, and stabilization in 81.4 % vs. 80.9 % of patients in the EVR + rTAC vs. MMF + TAC groups, respectively). There were no significant differences in the incidence of acute rejection (5.7 % vs. 3.8 %), deaths (5.7 % vs. 2.8 %), and serious adverse events (51.9 % vs. 44.0 %) between the 2 groups. CONCLUSION: EVR + rTAC allows a safe reduction in tacrolimus exposure in de novo liver transplant recipients, with a significant improvement in eGFR but without significant differences in renal clinical benefit 1 year after liver transplantation.

ABSTRACT

Tacrolimus (TAC) is a dose-dependent immunosuppressor with considerable intrapatient variability (IPV) in its pharmacokinetics. The aim of this work is to ascertain the association between TAC IPV at 6 months after liver transplantation (LT) and patient outcome. This single-center cohort study retrospectively analyzed adult patients who underwent transplantation from 2015 to 2019 who survived the first 6 months with a functioning graft. The primary end point was the patient's probability of death and the secondary outcome was the loss of renal function between month 6 and the last follow-up. TAC IPV was estimated by calculating the coefficient of variation (CV) of the dose-corrected concentration (C0 /D) between the third and sixth months post-LT. Of the 140 patients who underwent LT included in the study, the low-variability group (C0 /D CV < 27%) comprised 105 patients and the high-variability group (C0 /D CV ≥ 27%) 35 patients. One-, 3-, and 5-year patient survival rates were 100%, 82%, and 72% in the high-variability group versus 100%, 97%, and 93% in the low-variability group, respectively (p = 0.005). Moreover, significant impaired renal function was observed in the high-variability group at 1 year (69 ± 16 ml/min/1.73 m2 vs. 78 ± 16 ml/min/1.73 m2 , p = 0.004) and at 2 years post-LT (69 ± 17 ml/min/1.73 m2 vs. 77 ± 15 ml/min/1.73 m2 , p = 0.03). High C0 /D CV 3-6 months remained independently associated with worse survival (hazard ratio = 3.57, 95% CI = 1.32-9.67, p = 0.012) and loss of renal function (odds ratio = 3.47, 95% CI = 1.30-9.20, p = 0.01). Therefore, high IPV between the third and sixth months appears to be an early and independent predictor of patients with poorer liver transplant outcomes.

ABSTRACT

Postmortem normothermic regional perfusion (NRP) is a rising preservation strategy in controlled donation after circulatory determination of death (cDCD). Herein, we present results for cDCD liver transplants performed in Spain 2012-2019, with outcomes evaluated through December 31, 2020. Results were analyzed retrospectively and according to recovery technique (abdominal NRP [A-NRP] or standard rapid recovery [SRR]). During the study period, 545 cDCD liver transplants were performed with A-NRP and 258 with SRR. Median donor age was 59 years (interquartile range 49-67 years). Adjusted risk estimates were improved with A-NRP for overall biliary complications (OR 0.300, 95% CI 0.197-0.459, p < .001), ischemic type biliary lesions (OR 0.112, 95% CI 0.042-0.299, p < .001), graft loss (HR 0.371, 95% CI 0.267-0.516, p < .001), and patient death (HR 0.540, 95% CI 0.373-0.781, p = .001). Cold ischemia time (HR 1.004, 95% CI 1.001-1.007, p = .021) and re-transplantation indication (HR 9.552, 95% CI 3.519-25.930, p < .001) were significant independent predictors for graft loss among cDCD livers with A-NRP. While use of A-NRP helps overcome traditional limitations in cDCD liver transplantation, opportunity for improvement remains for cases with prolonged cold ischemia and/or technically complex recipients, indicating a potential role for complimentary ex situ perfusion preservation techniques.

ABSTRACT

BACKGROUND: Primary abdominal wall closure after pediatric liver transplantation (PLT) is neither always possible nor advisable, given the graft-recipient size discrepancy and its potential large-for-size scenario. Our objective was to report the experience accumulated with delayed sequential closure (DSC) guided by Doppler ultrasound control. METHODS: Retrospective analysis of DSC performed from 2013 to March 2020. RESULTS: Twenty-seven DSC (26.5%) were identified out of 102 PLT. Transplant indications and type of grafts were similar among both groups. In patients with DSC, mean weight and GRWR were 9.4 ± 5.5 kg (3.1-26 kg) and 4.7 ± 2.4 (1.9-9.7), significantly lower and higher than the primary closure cohort, respectively. The median time to achieve definitive closure was 6 days (range 3-23 days), and the median number of procedures was 4 (range 2-9). Patients with DSC had longer overall PICU (22.5 ± 16.9 vs. 9.1 ± 9.7 days, p < .05) and hospital stay (33.4 ± 19.1 vs 23, 9 ± 19.8 days (p < .05). These differences are less remarkable if the analysis is performed in a subgroup of patients weighing less than 10 kg. Two patients presented vascular complications (7.4%) within DSC group. No differences were seen when comparing overall, 3-year graft and patient survival (96% and 96% in the DSC group). CONCLUSIONS: DSC is a simple and safe technique to ensure satisfactory clinical outcomes to overcome "large for size" scenarios in PLT. In addition, we were able to avoid using a permanent biological material for closing the abdomen.

ABSTRACT

BACKGROUND: Infection in acute pancreatitis will worsen the disease prognosis. The aim of our study was to analyze the role of procalcitonin as a prognostic biomarker for infections and clinical severity. METHOD: A prospective single-cohort observational study of patients diagnosed of acute pancreatitis (n = 152) was designed. PCT determination was tested on admission (first 72 h). Infections (biliary, extrapancreatic and infected pancreatic necrosis), need for antibiotics, urgent ERCP and severity scores for acute pancreatitis was assessed. ROC curves were designed and the area under the curve was calculated. Logistic regression for multivariate analysis was performed to evaluate the association between procalcitonin optimal cut-off level and major complications. RESULTS: PCT >0.68 mg/dL had higher incidence of global infection, acute cholangitis, bacteraemia, infected pancreatic necrosis, use of antibiotics in general, and need for urgent ERCP. In the multivariate regressions analysis, PCT >0.68 mg/dL at admission demonstrated to be a strong risk factor for complications in acute pancreatitis. DISCUSSION: PCT levels can be used as a reliable laboratory test to predict infections and the clinical severity of acute pancreatitis. High levels of PCT predict antibiotics prescription as well as the need for urgent ERCP in patients with concomitant clinically severe cholangitis.

ABSTRACT

Background: Changes in BUN have been proposed as a risk factor for complications in acute pancreatitis (AP). Our study aimed to compare changes in BUN versus the Bedside Index for Severity in Acute Pancreatitis (BISAP) score and the Acute Physiology and Chronic Health Evaluation-II score (APACHE-II), as well as other laboratory tests such as haematocrit and its variations over 24 h and C-reactive protein, in order to determine the most accurate test for predicting mortality and severity outcomes in AP. Methods: Clinical data of 410 AP patients, prospectively enrolled for study at our institution, were analyzed. We define AP according to Atlanta classification (AC) 2012. The laboratory test's predictive accuracy was measured using area-under-the-curve receiver-operating characteristics (AUC) analysis and sensitivity and specificity tests. Results: Rise in BUN was the only score related to mortality on the multivariate analysis (p=0.000, OR: 12.7; CI 95%: 4.2-16.6). On the comparative analysis of AUC, the rise in BUN was an accurate test in predicting mortality (AUC: 0.842) and persisting multiorgan failure (AUC: 0.828), similar to the BISAP score (AUC: 0.836 and 0.850) and APACHE-II (AUC: 0.756 and 0.741). The BISAP score outperformed both APACHE-II and rise in BUN at 24 hours in predicting severe AP (AUC: 0.873 vs. 0.761 and 0.756, respectively). Conclusion: Rise in BUN at 24 hours is a quick and reliable test in predicting mortality and persisting multiorgan failure in AP patients.

ABSTRACT

OBJECTIVE: Our main purpose was to compare the modified computed tomography severity index (MCTSI), computed tomography severity index (CTSI), and acute physiological and chronic health evaluation (APACHE)-II predictions regarding severity according to the revised Atlanta classification 2012 and local complications in acute pancreatitis in a consecutive prospective cohort. METHODS: One hundred and forty-nine patients diagnosed with acute pancreatitis were prospectively enrolled. APACHE-II, MCTSI, and CTSI were calculated for all cases. Severity parameters included persistent organ or multiorgan failure, length of hospitalization, the need for intensive care, death, and local complications (intervention against necrosis and infected necrosis). Area under the receiver operating characteristic curve (AUROC) was calculated and the value of scoring systems was compared. RESULTS: Both CTSI and MCTSI were associated significantly with all the evaluated severity parameters and showed a correlation between imaging severity and the worst clinical outcomes. Persistent organ failure, persistent multiorgan failure, and death were found in 30 (20.1%), 20 (13.4%), and 13 (8.7%) patients, respectively. The most common extrapancreatic finding was pleural effusion in 76 (51.0%) patients. The AUROC for CTSI was higher for predicting persistent organ failure (0.749, 95% confidence interval [CI] 0.640-0.857), death (AUROC 0.793, 95% CI 0.650-0.936), intervention against necrosis (AUROC 0.862, 95% CI 0.779-0.945), and infected necrosis (AUROC 0.883, 95% CI 0.882-0.930). CONCLUSIONS: CT indexes outperformed the classic APACHE-II score for evaluating severity parameters in acute pancreatitis, with a slight advantage of CTSI over MCTSI. CTSI accurately predicted pancreatic infections and the need for intervention.

ABSTRACT

BACKGROUND AND AIMS: The demand for older patients not to be denied access to liver transplantation (LT) has intensified as the European population continues to live longer and maintains better health. AIM: This study aims to ascertain the impact of recipient age on the post-LT survival in 2 well-balanced populations at Vall d'Hebron University Hospital. METHODS: From January 1990 to December 2016, LT recipients (young group: 50-65 years of age; elderly group: >65 years of age) were compared by means of a propensity score matching (PSM) method. RESULTS: Prior to PSM, graft survival and patient survival were worse for the elderly group (P < .001). In 1126 LT recipients, a caliper width of 0.01 was used based on the donor (age, sex, cause of donor death, and donor intensive care unit stay) and recipient covariates (sex, body mass index, indication for LT, intraoperative blood transfusion, cardiovascular risk factors, and Model for End-Stage Liver Disease [MELD]-Era). After PSM, 206 patients were matched; 1-, 5-, and 10-year patient survival rates were 77%, 63%, and 52% vs 80%, 64%, and 45% (P = .50) for young vs elderly recipients, respectively. Similar graft survival rates were observed in both groups (P = .42). CONCLUSIONS: Advanced age alone should not exclude patients from LT.

ABSTRACT

Bacterial infections are an important threat in the early post-liver transplantation period. Donor-transmitted infections, although rare, can have high mortality. The utility of routine culture from the donor bile duct as screening of donor-transmitted infection has not been evaluated. We performed a retrospective study of 200 consecutive liver transplants between 2010 and 2015. Demographic, clinical, and microbiological data were collected from the recipients' medical records. Clinical data included pretransplantation, perioperative, and posttransplantation information (until 30 days after the procedure). The 3-month patient survival and/or retransplantation were recorded. A total of 157 samples from the donor bile duct were collected and cultured. Only 8 were positive. The microorganisms isolated were as follows: Klebsiella pneumoniae, n = 2; Escherichia coli, n = 1; Enterobacter cloacae, n = 1; Streptococcus anginosus, n = 1; Streptococcus sp., n = 1; multiple gram-negative bacilli, n = 1; and polymicrobial, n = 1. All of the microorganisms were susceptible to the antibiotic prophylaxis administered. During the first month after transplantation, 81 recipients developed 131 infections. Only 1 of these recipients had a donor with a positive bile culture, and none of the infections were due to the microorganism isolated in the donor's bile. The 3-month overall survival was 89.5%, and there were no differences between recipients with positive donor bile cultures and those with negative donor bile cultures (87.5% versus 89.26%; P > 0.99). Routine testing of donor bile cultures does not predict recipients' infection or survival after liver transplantation and should not be recommended.

ABSTRACT

INTRODUCCIÓN: El objetivo del presente estudio es analizar el impacto de la afectación del ganglio de la arteria hepática (GAH) en la supervivencia de los pacientes intervenidos de duodenopancreatectomía cefálica (DPC) por adenocarcinoma (ADK) de cabeza de páncreas. MÉTODOS: Estudio retrospectivo unicéntrico de pacientes intervenidos de DPC por ADK de cabeza de páncreas, con estudio anatomopatológico independiente del GAH. Los pacientes se agruparon en: 1) pacientes sin afectación del GAH ni ganglios peripancreáticos (GGP) (GPP-/GAH-); 2) pacientes con afectación ganglionar peripancreática (GPP+/GAH-), y 3)pacientes con afectación ganglionar peripancreática y de la arteria hepática (GGP+/GAH+). Para el análisis de supervivencia se utilizaron las curvas Kaplan-Meier. Los factores pronósticos de supervivencia global (SG) y libre de enfermedad (SLE) fueron identificados mediante el análisis de regresión de Cox. RESULTADOS: Entre enero de 2005 y diciembre de 2014 se intervinieron 118 pacientes, y el GAH fue analizado en 64 de ellos. La mediana de seguimiento fue de 20 meses (r: 1-159 meses). La distribución por grupos fue la siguiente: GPP-/GAH- en 12 (19%), GPP+/GAH- en 40 (62%), GGP+/GAH+ en 12 (19%) y CGP-/CGH+ en 0 (0%), La SG a 1, 3 y 5años fue estadísticamente mejor en el grupo GPP-/GAH- (82, 72 y 54%) comparado con GPP+/GAH- (68, 29 y 21%) y GGP+/GAH+ (72, 9 y 9%) (p = 0,001 vs p = 0,007). La probabilidad acumulada de recidiva a 1, 3 y 5 años fue estadísticamente inferior en el grupo GPP-/GAH- (18, 46 y 55%) comparado con el grupo GPP+/GAH- (57, 80 y 89%) y grupo GGP+/GAH+ (46, 91 y 100%) (p = 0,006 vs p = 0,021). En el análisis multivariante el principal factor de riesgo tanto de SG como de SLE fue la invasión linfática independientemente del estado del GAH. CONCLUSIONES: Nuestros resultados sugieren que la afectación adenopática impacta en la supervivencia del ADK de páncreas sin poder identificar la afectación del GAH como marcador pronóstico


INTRODUCTION: The aim of this study is to analyze the impact of hepatic artery lymph node (HALN) involvement on the survival of patients undergoing pancreaticoduodenectomy (PD) for pancreatic adenocarcinoma (PA). METHODS: A single-center retrospective study analyzing patients who underwent PD for PA. Patients were included if, during PD, the HALN was submitted for pathologic evaluation. Patients were stratified by node status: PPLN- (peripancreatic lymph node)/HALN-, PPLN+/HALN- and PPLN+/HALN+. Survival analysis was estimated by the Kaplan-Meier method, and Cox regression was used for risk factors analyses. RESULTS: Out of the 118 patients who underwent PD for PA, HALN status was analyzed in 64 patients. The median follow-up was 20months (r: 1-159months). HALN and PPLN were negative in 12 patients (PPLN-/HALN-, 19%), PPLN was positive and HALN negative in 40 patients (PPLN+/HALN-, 62%), PPLN and HALN were positive in 12 patients (PPLN+/HALN+, 19%) and PPLN was negative and HALN positive in 0 patients (PPLN-/HALN+, 0%). The overall 1, 3 and 5-year survival rates were statistically better in the PPLN-/HALN- group (82%, 72%, 54%) than in the PPLN+/HALN- group (68%, 29%, 21%) and the PPLN+/HALN+ group (72%, 9%, 9%, respectively) (P = .001 vs P = .007). The 1, 3 and 5-year probabilities of cumulative recurrence were also statistically better in the PPLN-/HALN- group (18%, 46%, 55%) than in the PPLN+/HALN- group (57%, 80%, 89%) and the PPLN+/HALN+ group (46%, 91%, 100%, respectively) (P = .006 vs P = .021). In the multivariate model, the main risk factor for overall survival and recurrence was lymphatic invasion, regardless of HALN status. CONCLUSIONS: In pancreatic adenocarcinoma patients with lymph node disease, survival after PD is comparable regardless of HALN status

ABSTRACT

We aimed to evaluate the safety and efficacy of low doses of anti-T-lymphocyte globulin (ATG)-based immunosuppression in preserving renal function and preventing liver rejection in liver transplant (LT) recipients with pretransplant renal dysfunction. We designed a prospective single-center cohort study analyzing patients with pre-LT renal dysfunction defined as eGFR<60 mL/min/1.73m2, who underwent induction therapy with ATG (ATG group, n=20). This group was compared with a similar retrospective cohort treated with basiliximab (BAS group, n=20). An economic analysis between both induction therapies was also undertaken. In the ATG group, 45% and 50% of patients had recovered their renal function without acute cellular rejection (ACR) episodes at day 7 and 1 month after LT, respectively, versus 40% and 55% of patients in the BAS group (p=1). Renal function improved in both groups over time and no differences between groups were observed regarding one-year eGRF and one-year probability of ACR. Cost per patient of the ATG course was 403€ (r: 126-756) versus 2,524€ of the basiliximab course (p=0.001). In conclusion, induction with low dose of ATG or basiliximab in patients with pretransplant renal dysfunction is a good strategy for preserving posttransplant renal function; however the use of low-dose ATG resulted in a substantial reduction in drug costs. This trail is registered with ClinicalTrials.gov number: NCT01453218.

ABSTRACT

This brief report presents the results of 20 adult and pediatric patients treated with the use of biodegradable SX-Ella biliary stents placed by means of a transhepatic approach for the treatment of benign biliary strictures after liver transplantation. Stent insertions were always feasible (100%), and only 1 case of acute pancreatitis was observed (5%). The overall clinical success rate of the procedure, including anastomotic and nonanastomotic strictures, was 75%, and was higher in the anastomotic stricture group (81.25%) than in the nonanastomotic stricture group (50%).

BACKGROUND: The aim of our study was to determine the risk factors for extrapancreatic infection (EPI) occurrence and its predictive power for assessing severity and local complications in acute pancreatitis including infected pancreatic necrosis (IPN). METHODS: Clinical data of 176 AP patients prospectively enrolled were analysed. EPI analysed were bacteraemia, lung infection, urinary tract infection and catheter line infection. Risk factors analysed were: Leukocyte count, C-reactive protein, liver function test, serum calcium, serum glucose, Blood urea nitrogen, mean arterial pressure at admission, total parenteral nutrition (TPN), enteral nutrition, hypotension, respiratory, cardiovascular and renal failure at admission, persistent systemic inflammatory response (SIRS) and intrapancreatic necrosis. Severity outcomes assessed were defined according to the Atlanta Criteria definition for acute pancreatitis. The predictive accuracy of EPI for morbidity and mortality was measured using area-under-the-curve (AUC) receiver-operating characteristics. RESULTS: Forty-four cases of EPI were found (25%). TPN (OR:9.2 CI95%: 3.3-25.7), APACHE-II>8 (OR:6.2 CI95%:2.48-15.54) and persistent SIRS (OR:2.9 CI95%: 1.1-7.8), were risk factors related with EPI. Bacteraemia, when compared with others EPI, showed the best accuracy in predicting significantly persistent organ failure (AUC:0.76, IC95%:0.64-0.88), ICU admission (AUC:0.80 IC95%:0.65-0.94), and death (AUC:0.73 CI95%:0.54-0.91); and for local complications including IPN (AUC:0.72 CI95%:0.53-0.92) as well. Besides, it was also needed for an interventional procedure against necrosis (AUC:0.74 IC95%: 0.57-0.91). When bacteraemia and IPN occurs, bacteraemia preceded infected necrosis in all cases. On multivariate analysis, risk factor for IPN were lung infection (OR:6.25 CI95%1.1-35.7 p = 0.039) and TPN (OR:22.0CI95%:2.4-205.8, p = 0.007), and for mortality were persistent SIRS at first week (OR: 22.9 CI95%: 2.6-203.7, p = 0.005) and Lung infection (OR: 9.7 CI95%: 1.7-53.8). CONCLUSION: In our study, EPI, played a role in predicting the severity and local complications in acute pancreatitis.

ABSTRACT

Reactivation of Chagas disease in the chronic phase may occur after solid organ transplantation, which may result in high parasitemia and severe clinical manifestations such as myocarditis and meningoencephalitis. The aim of the present study is to describe the prevalence of Chagas disease among solid organ-transplanted patients in a tertiary hospital from a nonendemic country. A cross-sectional study was performed at Vall d'Hebron University Hospital (Barcelona, Spain) from April to September 2016. Chagas disease screening was performed through serological tests in adult patients coming from endemic areas that had received solid organ transplantation and were being controlled in our hospital during the study period. Overall, 42 patients were included, 20 (47.6%) were male and median age was 50.5 (23-73) years. Transplanted organs were as follows: 18 kidneys, 17 lungs, and 7 livers. Three patients had Chagas disease, corresponding to a prevalence among this group of solid organ-transplanted patients of 7.1%. All three patients were born in Bolivia, had been diagnosed with Chagas disease and received specific treatment before the organ transplantation. We highly recommend providing screening tests for Chagas disease in patients with or candidates for solid organ transplantation coming from endemic areas, early treatment with benznidazole, and close follow-up to prevent clinical reactivations.

ABSTRACT

BACKGROUND The characteristics of liver donors have changed over the last decade owing to the shortage of organs and high mortality on the waiting list, leading to wider use of extended-criteria donors, including older donors. The aim of this study was to evaluate the effect of matching donor-recipient age on morbidity at 1 year post-transplant and on long-term patient and graft survival. MATERIAL AND METHODS Retrospective study from a prospectively-obtained database including adult patients who had received a primary liver transplant (LT) from whole graft of brain-dead donors. Recipients were divided into 2 age groups: <60 years and ≥60 years. Both groups were sub-divided according to donor age (younger than 60 years and 60 years or older). A propensity score analysis was performed to further adjust for baseline differences between recipients and donors. RESULTS We analyzed 642 patients who had LT performed between January 2000 and December 2013. No differences were observed in 1-year morbidity (hospital stay, rejection, surgical complications, and retransplant) between groups. Although patient and graft survival was significantly impaired in the older donor/older recipient group on Kaplan-Meier analysis (p=0.004), the propensity score analysis showed that donor age ≥60 years did not increase the risk of death for recipients aged ≥60 (HR1.40, p 0.074) and <60 years (HR 1.47, p 0.070). CONCLUSIONS Older donor age did not negatively affect survival regardless of recipient age, and comparable outcomes were achieved without an increased rate of complications.

ABSTRACT

AIM: To describe one case of bilateral Tapia's syndrome in a liver transplanted patient and to review the literature. METHODS: We report a case of bilateral Tapia's syndrome in a 50-year-old man with a history of human immunodeficiency virus and hepatitis C virus child. A liver cirrhosis and a bi-nodular hepatocellular carcinoma, who underwent liver transplantation after general anesthesia under orotracheal intubation. Uneventful extubation was performed in the intensive care unit during the following hours. On postoperative day (POD) 3, he required urgent re-laparotomy due to perihepatic hematoma complicated with respiratory gram negative bacilli infection. On POD 13, patient was extubated, but required immediate re-intubation due to severe respiratory failure. At the following day a third weaning failure occurred, requiring the performance of a percutaneous tracheostomy. Five days later, the patient was taken off mechanical ventilation and severe dysphagia, sialorrea and aphonia revealed. A computerized tomography and a magnetic resonance imaging of the head and neck excluded central nervous injury. A stroboscopy showed bilateral paralysis of vocal cords and tongue and a diagnosis of bilateral Tapia's syndrome was performed. With conservative management, including a prompt establishment of a speech and swallowing rehabilitation program, the patient achieved full recovery within four months after liver transplantation. We carried out MEDLINE search for the term Tapia's syndrome. The inclusion criteria had no restriction by language or year but must provide sufficient available data to exclude duplicity. We described the clinical evolution of the patients, focusing on author, year of publication, age, sex, preceding problem, history of endotracheal intubation, unilateral or bilateral presentation, diagnostic procedures, type of treatment, follow-up, and outcome. RESULTS: Several authors mentioned the existence of around 70 cases, however only 54 fulfilled our inclusion criteria. We found only five published studies of bilateral Tapia's syndrome. However this is the first case reported in the literature in a liver transplanted patient. Most patients were male and young and the majority of cases appeared as a complication of airway manipulation after any type of surgery, closely related to the positioning of the head during the procedure. The diagnosis was founded on a rapid suspicion, a complete head and neck neurological examination and a computed tomography and or a magnetic resonance imaging of the brain and neck to establish the origin of central or peripheral type of Tapia's syndrome and also the nature of the lesion, ischemia, abscess formation, tumor or hemorrhage. Apart from corticosteroids and anti- inflammatory therapy, the key of the treatment was an intensive and multidisciplinary speech and swallowing rehabilitation. Most studies have emphasized that the recovery is usually completed within four to six months. CONCLUSION: Tapia's syndrome is almost always a transient complication after airway manipulation. Although bilateral Tapia's syndrome after general anesthesia is exceptionally rare, this complication should be recognized in patients reporting respiratory obstruction with complete dysphagia and dysarthria after prolonged intubation. Both anesthesiologists and surgeons should be aware of the importance of its preventing measurements, prompt diagnosis and intensive speech and swallowing rehabilitation program.

ABSTRACT

INTRODUCCIÓN: El beneficio de la duodenopancreatectomía cefálica (DPC) con resección de la vena mesentérica superior/vena porta (RVP) para el adenocarcinoma de páncreas (ADCP) es controvertido en cuanto a la morbilidad, mortalidad y supervivencia. Se analizan los resultados de la DPC con RVP en un centro terciario español. MÉTODOS: Entre 2002 y 2012, 10 pacientes fueron tratados mediante RVP (RVP+) y 68 con DPC estándar (RVP−). La morbilidad, mortalidad, supervivencia global (SG) y supervivencia libre de enfermedad (SLE) se compararon entre pacientes RVP+/RVP−. Los factores pronósticos fueron identificados con regresión de Cox. RESULTADOS: La mortalidad postoperatoria fue del 5% (4/78), todos los pacientes en el grupo RVP−. La morbilidad fue mayor en el grupo RVP− comparado con RVP+ (63 vs. 30%; p = 0,04). La SG a 3 y 5 años fue 43 y 43% en el grupo RVP+, 35 y 29% en RVP− (p = 0,7). La SLE a 3 y 5 años fue 28 y 15% en RVP+, 25 y 20% en RVP− (p = 0,84). La mediana de supervivencia fue de 23,1 meses en el grupo RVP− y de 22,8 meses en el grupo RVP+ (p = 0,73). Los factores relacionados con la SG fueron ausencia de tratamiento adyuvante (OR 2,9; IC95%: 1,39-6,14; p = 0,003), resección R1 (OR 2,3; IC95%: 1,2-4,43; p = 0,006), CA 19.9 ≥ 170 UI/mL (OR 2,3; IC95%: 1,22-4,32; p = 0,01). Los factores de riesgo para SLE fueron resección R1 (OR 2,6; IC95%: 1,41-4,95; p = 0,002); tumores pobremente diferenciados (OR 2,7; IC95%: 1,23-6,17; p = 0,01); tumores N1 (OR 1,8; IC95%: 1,02-3,19; p = 0,04); CA 19.9 ≥ 170 UI/mL (OR 2,4; IC95%: 1,30-4,54; p = 0,005). CONCLUSIONES: La RVP para ADCP puede realizarse con seguridad. Pacientes con RVP tienen una supervivencia comparable a los pacientes tratados mediante DPC estándar si se obtienen márgenes libres


INTRODUCTION: The benefit of pancreaticoduodenectomy (PD) with superior mesenteric-portal vein resection (PVR) for pancreatic adenocarcinoma (PA) is still controversial in terms of morbidity, mortality and survival. We conducted a retrospective study to analyze outcomes of PD with PVR in a Spanish tertiary centre. METHODS: Between 2002 and 2012, 10 patients underwent PVR (PVR+ group) and 68 standard PD (PVR− group). Morbidity, mortality, overall survival (OS) and disease-free survival (DFS) were compared between PVR+ and PVR− group. Prognostic factors were identified by a Cox regression model. RESULTS: Postoperative mortality was 5% (4/78), all patients in PVR− group. Morbidity was higher in the PVR− group compared to PVR+ (63 vs. 30%, P=.004). OS at 3 and 5 years was 43 and 43% in PVR+ group, 35 and 29% in PVR− group (P=.07). DFS at 3 and 5 years DFS were 28 and 15% in PVR+ group, 25 and 20% in PVR− group (P=.84). Median survival was 23.1 months in PVR− group, and 22.8 months in PVR+ group (P=.73). Factors related with OS were absence of adjuvant treatment (OR 2.9, 95%IC: 1.39-6.14, P=.003), R1 resection (OR 2.3, 95%IC: 1.2-4.43, P=.006), preoperative CA 19.9 level ≥ 170 UI/mL (OR 2.3, 95%IC: 1.22-4.32, P=.01). DFS risk factors were R1 resection (OR 2.6, 95%IC: 1.41-4.95, P=.002); moderate or poor tumor differentiation grade (OR 2.7, 95%IC: 1.23-6.17, P=.01); N1 lymph node status (OR 1.8, 95%IC: 1.02-3.19, P=.04); CA 19.9 level ≥ 170 UI/mL (OR 2.4, 95%IC: 1.30-4.54, P=.005). CONCLUSIONS: PVR for PA can be performed safely. Patients with PVR have a comparable survival to patients undergoing standard PD if disease-free margins can be obtained
