Prevention of biliary fistula after partial hepatectomy by transcystic biliary drainage: randomized clinical trial.

BACKGROUND: Biliary fistula is one of the most common complications after hepatectomy. This study evaluated the effect of transcystic biliary drainage during hepatectomy on the occurrence of postoperative biliary fistula. METHODS: This multicentre RCT was carried out from 2009 to 2016 in nine centres. Patients were randomized to transcystic biliary drainage or no transcystic drainage (control). Patients underwent hepatectomy (more than 2 segments) of non-cirrhotic livers. The primary endpoint was the occurrence of biliary fistula after surgery. Secondary endpoints were morbidity, postoperative mortality, duration of hospital stay, reoperation, readmission to hospital, and complications caused by catheters. Intention-to-treat and per-protocol analyses were performed. RESULTS: A total of 310 patients were randomized. In intention-to-treat analysis, there were 158 patients in the transcystic group and 149 in the control group. Seven patients were removed from the per-protocol analysis owing to protocol deviations. The biliary fistula rate was 5·9 per cent in intention-to-treat and 6·0 per cent in per-protocol analyses. The rate was similar in the transcystic and control groups (5·7 versus 6·0 per cent; P = 1·000). There were no differences in terms of morbidity (49·4 versus 46·3 per cent; P = 0·731), mortality (2·5 versus 4·7 per cent; P = 0·367) and reoperations (4·4 versus 10·1 per cent; P = 1·000). Median duration of hospital stay was longer in the transcystic group (11 versus 10 days; P = 0·042). The biliary fistula risk was associated with the width and length of the hepatic cut surface. CONCLUSION: This randomized trial did not demonstrate superiority of transcystic drainage during hepatectomy in preventing biliary fistula. The use of transcystic drainage during hepatectomy to prevent postoperative biliary fistula is not recommended. Registration number: NCT01469442 ( http://www.clinicaltrials.gov).

ANTECEDENTES: La fístula biliar es una de las complicaciones más comunes después de la hepatectomía. Este estudio evalúa el efecto del drenaje biliar transcístico durante la hepatectomía en la aparición de una fístula biliar postoperatoria. MÉTODOS: Este ensayo prospectivo aleatorizado y multicéntrico (Clinical Trial NCT01469442) con dos grupos de estudio (grupo transcístico versus grupo control) se llevó a cabo de 2009 a 2016 en 9 centros. Los pacientes fueron sometidos a una hepatectomía (≥ 2 segmentos) en hígados no cirróticos. El resultado principal fue la aparición de una fístula biliar después de la cirugía. Los resultados secundarios fueron la morbilidad, la mortalidad postoperatoria, la duración de la estancia hospitalaria, la reintervención, la necesidad de reingreso y las complicaciones causadas por los catéteres. Se realizaron análisis por intención de tratamiento y por protocolo. RESULTADOS: Un total de 310 pacientes fueron randomizados. Por intención de tratamiento, 158 pacientes fueron aleatorizados al grupo transcístico y 149 al grupo control. Siete pacientes fueron excluidos del análisis por protocolo por desviaciones del protocolo. La tasa de fístula biliar fue del 5,9% en el análisis por intención de tratamiento y del 6,0% en el análisis por protocolo. Esta tasa fue similar para el grupo transcístico y para el grupo control: 5,7% versus 6,0% (P = 1). No hubo diferencias en términos de morbilidad (49,4% versus 46,9%, P = 0,731), mortalidad (2,5% versus 4,7%, P = 0,367) y reintervenciones (4,4% versus 10,1%, P = 1). La mediana de la duración de la estancia hospitalaria fue mayor para el grupo transcístico (11 versus 10 días, P = 0,042). El riesgo de fístula biliar se correlacionó con el grosor y la longitud de la transección hepática. CONCLUSIÓN: Este ensayo aleatorizado no demuestra la superioridad del drenaje transcístico durante la hepatectomía para prevenir la fístula biliar. No se recomienda el uso de drenaje transcístico durante la hepatectomía para prevenir la fístula biliar postoperatoria.

Impact of cirrhosis in patients undergoing laparoscopic liver resection in a nationwide multicentre survey.

BACKGROUND: The aim was to analyse the impact of cirrhosis on short-term outcomes after laparoscopic liver resection (LLR) in a multicentre national cohort study. METHODS: This retrospective study included all patients undergoing LLR in 27 centres between 2000 and 2017. Cirrhosis was defined as F4 fibrosis on pathological examination. Short-term outcomes of patients with and without liver cirrhosis were compared after propensity score matching by centre volume, demographic and tumour characteristics, and extent of resection. RESULTS: Among 3150 patients included, LLR was performed in 774 patients with (24·6 per cent) and 2376 (75·4 per cent) without cirrhosis. Severe complication and mortality rates in patients with cirrhosis were 10·6 and 2·6 per cent respectively. Posthepatectomy liver failure (PHLF) developed in 3·6 per cent of patients with cirrhosis and was the major cause of death (11 of 20 patients). After matching, patients with cirrhosis tended to have higher rates of severe complications (odds ratio (OR) 1·74, 95 per cent c.i. 0·92 to 3·41; P = 0·096) and PHLF (OR 7·13, 0·91 to 323·10; P = 0·068) than those without cirrhosis. They also had a higher risk of death (OR 5·13, 1·08 to 48·61; P = 0·039). Rates of cardiorespiratory complications (P = 0·338), bile leakage (P = 0·286) and reoperation (P = 0·352) were similar in the two groups. Patients with cirrhosis had a longer hospital stay than those without (11 versus 8 days; P = 0·018). Centre expertise was an independent protective factor against PHLF in patients with cirrhosis (OR 0·33, 0·14 to 0·76; P = 0·010). CONCLUSION: Underlying cirrhosis remains an independent risk factor for impaired outcomes in patients undergoing LLR, even in expert centres.

ANTECEDENTES: El objetivo de este estudio fue analizar el impacto de la cirrosis en los resultados a corto plazo después de la resección hepática laparoscópica (laparoscopic liver resection, LLR) en un estudio de cohortes multicéntrico nacional. MÉTODOS: Este estudio retrospectivo incluyó todos los pacientes sometidos a LLR en 27 centros entre 2000 y 2017. La cirrosis se definió como fibrosis F4 en el examen histopatológico. Los resultados a corto plazo de los pacientes con hígado cirrótico (cirrhotic liver CL) (pacientes CL) y los pacientes con hígado no cirrótico (non-cirrhotic liver, NCL) (pacientes NCL) se compararon después de realizar un emparejamiento por puntaje de propension del volumen del centro, las características demográficas y del tumor, y la extensión de la resección. RESULTADOS: Del total de 3.150 pacientes incluidos, se realizó LLR en 774 (24,6%) pacientes CL y en 2.376 (75,4%) pacientes NCL. Las tasas de complicaciones graves y mortalidad en el grupo de pacientes CL fueron del 10,6% y 2,6%, respectivamente. La insuficiencia hepática posterior a la hepatectomía (post-hepatectomy liver failure, PHLF) fue la principal causa de mortalidad (55% de los casos) y se produjo en el 3,6% de los casos en pacientes CL. Después del emparejamiento, los pacientes CL tendieron a tener tasas más altas de complicaciones graves (razón de oportunidades, odds ratio, OR 1,74; i.c. del 95% 0,92-0,41; P = 0,096) y de PHLF (OR 7,13; i.c. del 95% 0,91-323,10; P = 0,068) en comparación con los pacientes NCL. Los pacientes CL estuvieron expuestos a un mayor riesgo de mortalidad (OR 5,13; i.c. del 95% 1,08-48,6; P = 0,039) en comparación con los pacientes NCL. Los pacientes CL presentaron tasas similares de complicaciones cardiorrespiratorias graves (P = 0,338), de fuga biliar (P = 0,286) y de reintervenciones (P = 0,352) que los pacientes NCL. Los pacientes CL tuvieron una estancia hospitalaria más larga (11 versus 8 días; P = 0,018) que los pacientes NCL. La experiencia del centro fue un factor protector independiente de PHLF (OR 0,33; i.c. del 95% 0,14-0,76; P = 0,010) pacientes CL. CONCLUSIÓN: La presencia de cirrosis subyacente sigue siendo un factor de riesgo independiente de peores resultados en pacientes sometidos a resección hepática laparoscópica, incluso en centros con experiencia.

Prevalence, incidence and risk factors for donor-specific anti-HLA antibodies in maintenance liver transplant patients.

Although large retrospective studies have identified the presence of donor-specific antibodies (DSAs) to be a risk factor for rejection and impaired survival after liver transplantation, the long-term predicted pathogenic potential of individual DSAs after liver transplantation remains unclear. We investigated the incidence, prevalence and consequences of DSAs in maintenance liver transplant (LT) recipients. Two hundred sixty-seven LT recipients, who had undergone transplantation at least 6 months previously and had been screened for DSAs at least twice using single-antigen bead technology, were included and tested annually for the presence of DSAs. At a median of 51 months (min-max: 6-220) after an LT, 13% of patients had DSAs. At a median of 36.5 months (min-max: 2-45) after the first screening, 9% of patients have developed de novo DSAs. The sole predictive factor for the emergence of de novo DSAs was retransplantation (OR 3.75; 95% CI 1.28-11.05, p = 0.025). Five out of 21 patients with de novo DSAs (23.8%) developed an antibody-mediated rejection. Fibrosis score was higher among patients with DSAs. In conclusion, monitoring for the development of DSAs in maintenance LT patients is useful in case of graft dysfunction and to identify patients with a high risk of developing liver fibrosis.

Clinical decision-making training using the Script Concordance Test and simulation: A pilot study for pediatric residents.

BACKGROUND: Each year, new pediatric residents begin their shifts in the pediatric emergency room. While technical skills are often acquired during workshops, non-technical skills such as communication, professionalism, situational awareness, or decision-making are rarely tested. Simulation enables non-technical skills to be developed in situations frequently encountered in pediatric emergencies. Adopting an innovative approach, we combined two pedagogical methods: the Script Concordance Test (SCT) and simulation to improve clinical reasoning and non-technical skills of first-year pediatric residents in dealing with clinical situations involving febrile seizures. The aim of this work is to report the feasibility of such a combined training. METHODS: The first-year pediatric residents participated in a training session on how to manage a child attending the emergency department with a febrile seizure. At the beginning of the session, the trainees had to complete the SCT (seven clinical situations) and then participated in three simulation scenarios. Student satisfaction was assessed by means of a questionnaire at the end of the session. RESULTS: In this pilot study, 20 residents participated in the training. The SCT scores for the first-year pediatric residents were lower and more widely distributed than those of the experts with better concordance for diagnostic items compared to investigation or treatment items. All were satisfied with the teaching methods employed. Further sessions on additional topics relating to the management of pediatric emergency cases were requested. CONCLUSION: Although limited by the small size of our study, this combination of teaching methods was possible and seemed promising for the development of non-technical skills of pediatric residents. These methods are in line with the changes being made to the third cycle of medical studies in France and can be adapted to other situations and other specialties.

Gene expression signature of advanced pancreatic ductal adenocarcinoma using low density array on endoscopic ultrasound-guided fine needle aspiration samples.

AIMS: The purpose of this study was to investigate the clinical feasibility and utility of low-density array analysis on samples obtained from endoscopic ultrasound-guided fine needle aspiration biopsy in locally advanced and/or metastatic pancreatic ductal adenocarcinoma and chronic pancreatitis. PATIENTS AND METHODS: In this prospective multicenter study, we quantified candidate gene expression in biopsies sampled from 44 locally advanced and/or metastatic pancreatic carcinoma and from 17 pseudotumoural chronic pancreatitis using dedicated low-density array microfluidic plates. RESULTS: We first demonstrated that 18S gene expression is stable and comparable in normal pancreas and pancreatic cancer tissues. Next, we found that eight genes (S100P, PLAT, PLAU, MSLN, MMP-11, MMP-7, KRT7, KRT17) were significantly over expressed in pancreatic cancer samples when compared to pseudotumoural chronic pancreatitis (p value ranging from 0.0007 to 0.0215): Linear discriminative analysis identified S100P, PLAT, MSLN, MMP-7, KRT7 as highly explicative variables. The area under receiver operating curve establishes the clinical validity of the potential diagnostic markers identified in this study (values ranging from 0.69 to 0.76). In addition, combination of S100P and KRT7 gave better diagnosis performances (Area Under Receiver Operating Curve 0.81, sensitivity 81%, specificity 77%). CONCLUSION: We demonstrate that molecular studies on EUS-guided FNA material are feasible for the identification and quantification of markers in PDAC patients diagnosed with non-resectable tumours. Using low-density array, we isolated a molecular signature of advanced pancreatic carcinoma including mostly cancer invasion-related genes. This work stems for the use of novel biomarkers for the molecular diagnosis of patient with solid pancreatic masses.

Duodenal villous atrophy: a cause of chronic diarrhea after solid-organ transplantation.

Persistent diarrhea is commonly observed after solid organ transplantation (SOT). A few cases of mycophenolate mofetil (MMF)-induced duodenal villous atrophy (DVA) have been previously reported in kidney-transplant patients with chronic diarrhea. Herein, we report on the incidence and characteristics of DVA in SOT patients with chronic diarrhea. One hundred thirty-two SOT patients with chronic diarrhea underwent an oesophago-gastroduodenoscopy (OGD) and a duodenal biopsy after classical causes of diarrhea have been ruled out. DVA was diagnosed in 21 patients (15.9%). It was attributed to mycophenolic acid (MPA) therapy in 18 patients (85.7%) (MMF [n = 14] and enteric-coated mycophenolate sodium [n = 4]). MPA withdrawal or dose reduction resulted in diarrhea cessation. The incidence of DVA was significantly higher in patients with chronic diarrhea receiving MPA compared to those who did not (24.6% vs. 5.1%, p = 0.003). DVA was attributed to a Giardia lamblia parasitic infection in two patients (9.5%) and the remaining case was attributed to azathioprine. In these three patients, diarrhea ceased after metronidazole therapy or azathioprine dose reduction. In conclusion, DVA is a frequent cause of chronic diarrhea in SOT recipients. MPA therapy is the most frequent cause of DVA. An OGD should be proposed to all transplant recipients who present with persistent diarrhea.

Impact of the strategy for curative treatment of synchronous colorectal cancer liver metastases.

AIM OF THE STUDY: Fourteen to seventeen percent of patients suffering from colorectal cancer have synchronous liver metastases (sCRLM) at the time of diagnosis. There are currently three possible strategies for curative management of sCRLM: "classic", "combined", and "liver-first". The aim of our research was to analyze the effects of the three surgical management strategies for sCRLM on postoperative morbidity and mortality and overall and recurrence-free survival. PATIENTS AND METHODS: Patients treated for sCRLM between October 2000 and May 2015 were included. We defined three groups: (1) "classic": surgery of primary tumor and then surgery of sCRLM; (2) "combined": combined surgery of primary tumor and sCRLM: and (3) "liver-first": surgery of sCRLM and then surgery of primary tumor. RESULTS: During this period, 170 patients who underwent 209 hepatectomies were included ("classic": 149, "combined": 34, "liver-first": 26). The rate of severe complications was higher in the "combined" group compared to the "classic" group (35% vs. 12%, P=0.03), and the "liver-first" group (35% vs. 19%, P=0.25), while there were significantly fewer liver resections. Overall survival at 5 years in our cohort was 46%, without significant differences between the groups, and a median survival of 54 months. Recurrence-free survival of the patients in our cohort was 24% at 5 years, with a median survival time without recurrence of 14 months, without significant differences between the groups. CONCLUSION: All three strategies were feasible and there were no differences regarding overall and recurrence-free survivals between the three approaches. The "combined" strategy group had significantly more severe complications and did not provide better oncological results, despite less aggressive liver disease and more limited liver resections.

Short-term autonomy and survival after hepatectomy in the elderly.

AIM: To study morbi-mortality, survival after hepatectomy in elderly patients, and influence on their short-term autonomy. PATIENTS AND METHODS: This is a retrospective study conducted between 2002 and 2017 comparing patients less than 65 years old (controls) to those more than 65 years old (cases) from a prospective database, with retrospective collection of geriatric data. Cases were divided into three sub-groups (65-70 years, 70-80 years and>80 years). RESULTS: Four hundred and eighty-two patients were included. There was no age difference in number of major hepatectomies (P=0.5506), length of stay (P=0.3215), mortality at 90 days (P=0.3915), and surgical complications (P=0.1467). There were more Grade 1 Clavien medical complications among the patients aged over 65 years (P=0.1737). There was no difference in overall survival (P=0.460) or disease-free survival (P=0.108) according to age after adjustment for type of disease and hepatectomy. One-third of patients had geriatric complications. The "home discharge" rate decreased significantly with age from 92% to 68% (P=0.0001). Early loss of autonomy after hospitalization increased with age, 16% between 65 and 70 years, 23% between 70 and 80 years and 36% after 80 years (P=0.10). We identified four independent predictors of loss of autonomy: age>70 years, cholangiocarcinoma, length of stay>10 days, and metachronous colorectal cancer. CONCLUSIONS: Elderly patients had the same management as young patients, with no difference in surgery or survival, but with an increase in early loss of autonomy.

The value of 18F-FDG positron emission tomography to differentiate benign from malignant intraductal papillary mucinous neoplasms: A prospective multicenter study.

OBJECTIVE: To assess the value of 18F-FDG PET/CT in differentiating between benign and malignant intraductal papillary mucinous neoplasms (IPMN) of the pancreas. SUMMARY BACKGROUND DATA: Malignant or high-risk IPMN require surgical resection but surgery should be avoided in patients with IPMN carrying a low risk of malignancy. 18F-FDG PET has been studied mostly in small, single center, retrospective series. METHODS: Prospective, non-comparative, multicenter French study. The primary endpoint was the specificity of PET/CT for identifying malignant IPMN (in situ or invasive carcinoma). Final diagnosis was obtained from pathological examination of the resected specimen. RESULTS: Among 120 patients analyzed, 99 had confirmed IPMN, including 24 with malignant lesions, namely 9 with carcinoma in situ and 15 with invasive carcinoma. The 18F-FDG PET/CT was positive in 44 and 31 patients in the overall and IPMN populations respectively. In the 99 IPMN patients, PET/CT showed 13 true positive, 18 false positive, 57 true negative and 11 false negative results. The sensitivity, specificity, negative predictive value (NPV) and positive predictive value (PPV) for the diagnosis of malignancy were 54.2%, 76.0%, 83.8% and 41.9% respectively, versus 64.9%, 75.9%, 82.9% and 54.5% in the overall population. We could not identify a cut-off value for SUVmax to distinguish benign from malignant lesions. Conventional imaging included computed tomography, magnetic resonance cholangiopancreatography and endoscopic ultrasound. In IPMN patients who underwent the 3 techniques, sensitivity, specificity, NPV and PPV were 66.7%, 84.4%, 84.4% and 66.7% respectively. CONCLUSIONS: In this study, 18F-FDG PET/CT did not perform better than conventional imaging to differentiate malignant from benign IPMN.

Liberal selection criteria for liver transplantation for hepatocellular carcinoma.

BACKGROUND: To help increase the number of transplants available for hepatocellular carcinoma in cirrhotic livers, this single-centre retrospective study compared the safety and feasibility of new, more liberal, selection criteria--no more than five tumours, with the largest tumour no greater than 5 cm (5/5 criteria)--with classical criteria. METHODS: Data from operations performed in 1990-2005 were extracted from preoperative radiological findings and postoperative specimen analyses, and four groups were constructed: Paul Brousse, Milan, University of California, San Francisco (UCSF) and 5/5 criteria. A fifth group comprised patients whose tumour load exceeded the 5/5 criteria. Survival and recurrence rates were compared. RESULTS: For the 110 patients in the study, survival rates (overall and disease-free) were 72.8 and 66.8 per cent at 5 and 10 years respectively, with a 5.5 per cent recurrence rate. The 5-year survival rate was 65, 77, 68 and 77 per cent for Paul Brousse, Milan, UCSF and 5/5 preoperative radiological criteria, with recurrence rates of 4, 4, 3 and 3 per cent, respectively. On multivariable analysis, the only factor that influenced survival was tumour load in excess of the 5/5 criteria. CONCLUSION: Use of the more liberal 5/5 criteria for selecting patients for liver transplantation results in similar disease-free and overall survival rates to classical criteria.

Original Study: Transjugular Intrahepatic Portosystemic Shunt as a Bridge to Abdominal Surgery in Cirrhotic Patients.

BACKGROUND: Transjugular intrahepatic portosystemic shunt (TIPS) has been suggested to reduce portal hypertension-associated complications in cirrhotic patients undergoing abdominal surgery. The aim of this study was to compare postoperative outcome in cirrhotic patients with and without specific preoperative TIPS placement, following elective extrahepatic abdominal surgery. METHODS: Patients were retrospectively included from 2005 to 2016 in four centers. Patients who underwent preoperative TIPS (n = 66) were compared to cirrhotic control patients without TIPS (n = 68). Postoperative outcome was analyzed using propensity score with inverse probability of treatment weighting analysis. RESULTS: Overall, colorectal surgery accounted for 54% of all surgical procedure. TIPS patients had a higher initial Child-Pugh score (6[5-12] vs. 6[5-9], p = 0.043) and received more beta-blockers (65% vs. 22%, p < 0.001). In TIPS group, 56 (85%) patients managed to undergo planned surgery. Preoperative TIPS was associated with less postoperative ascites (hazard ratio = 0.330 [0.140-0.780]). Severe postoperative complications (Clavien-Dindo > 2) and 90-day mortality were similar between TIPS and no-TIPS groups (18% vs. 23%, p = 0.392, and 7.5% vs. 7.8%, p = 0.644, respectively). CONCLUSIONS: Preoperative TIPS placement yielded an 85% operability rate with satisfying postoperative outcomes. No significant differences were found between TIPS and no-TIPS groups in terms of severe postoperative complications and mortality, although TIPS patients probably had worse initial portal hypertension.

Erectile dysfunction in liver transplant patients.

The objectives of the study were to determine the frequency of erectile dysfunction (ED) after liver transplantation (LT) and discuss potential risk factors. Of 123 eligible LT men, 98 (79.7%) responded to a questionnaire about sexual function at a mean time posttransplant of 5.4 +/- 4.0 years (1.0-21). Erection was evaluated using the five-question international index for erectile function score, and sexual satisfaction by the patient-baseline treatment-satisfaction status (TSS) score. Questions also focused on patient perception of changes overtime. We found that after LT, the proportion of sexually inactive men decreased from 29% to 15% (p = 0.01), but the proportion of men with ED remained unchanged. The absence of sexual activity was associated with pretransplant sexual inactivity (p = 0.001), age (p = 0.008), cardiovascular disease (p = 0.03), use of diuretics (p = 0.04), anticoagulants (p = 0.001), statins (p = 0.01) and treatment for diabetes (p = 0.03). Cardiovascular disease (p = 0.05), posttransplantation diabetes (p = 0.04), alcohol abuse (p = 0.03), antidepressants (p = 0.05) and angiotensin II receptor blockers (p = 0.05) were associated with having ED after LT. Having a low TSS score was associated with a history of endocrine disease (p = 0.03), antidepressants (p = 0.04) and diuretics (p = 0.03). In conclusion, LT improves sexual activity, but ED is multifactorial and remains a long-term condition in the majority of patients.

Predictors of long-term survival after liver transplantation for metastatic endocrine tumors: an 85-case French multicentric report.

Liver transplantation (LTx) for metastatic endocrine tumors (MET) remains controversial due to the lack of clear selection criteria. From 1989 to 2005, 85 patients underwent LTx for MET. The primary tumor was located in the pancreas or duodenum in 40 cases, digestive tract in 26 and bronchial tree in five. In the remaining 14 cases, primary location was undetermined at the time of LTx. Hepatomegaly (explanted liver > or =120% of estimated standard liver volume) was observed in 53 patients (62%). Extrahepatic resection was performed concomitantly with LTx in 34 patients (40%), including upper abdominal exenteration (UAE) in seven. Postoperative in-hospital mortality was 14%. Overall 5-year survival was 47%. Independent factors of poor prognosis according to multivariate analysis included UAE (relative risk (RR): 3.72), primary tumor in duodenum or pancreas (RR: 2.94) and hepatomegaly (RR: 2.63). After exclusion of cases involving concomitant UAE, the other two factors were combined into a risk model. Five-year survival rate was 12% for the 23 patients presenting both unfavorable prognostic factors versus 68% for the 55 patients presenting one or neither factor (p < 10(-7)). LTx can benefit selected patients with nonresectable MET. Patients presenting duodeno-pancreatic MET in association with hepatomegaly are poor indications for LTx.

Liver transplantation with reconstruction of the inferior vena cava for hepatocarcinoma on chronic Budd-Chiari: a case report.

Management of Budd-Chiari syndrome, from simple medical treatment to liver transplantation, depends on the acute and chronic evolution of the disease and on the degree of hepatic insufficiency. Herein we have reported the case of a man who underwent transplantation after evolution of a Budd-Chiari syndrome with membranous obstruction of the vena cava and developed 2 lesions of hepatocellular carcinoma. Surgery was difficult due to previous procedures requiring reconstruction of the supra-hepatic vena cava. This case emphasized the timing of liver transplantation versus other treatments to decrease the operative risk.

Biological changes after liver transplantation according to the presence or not of graft steatosis.

AIM: To assess the consequences of graft steatosis on postoperative liver function as compared with normal liver grafts. PATIENTS AND METHODS: From January 2005 to December 2007, liver transplant patients were prospectively included, excluding those who experienced arterial or biliary complications or presented acute rejection. All patients had a surgical biopsy after reperfusion. Patients were compared according to the rate of macrovacuolar steatosis: namely above or below 20%. RESULTS: Fifty-three patients were included: 10 in the steatosis group and 43 in the control group. No significant difference was observed in terms of morbidity, mortality, and primary non- or poor function. Nevertheless, biological changes after the procedure were significantly different during the first postoperative week. Prothrombin time, serum bilirubin, and transaminases were significantly increased among the steatosis group compared with the control group (P < .05). CONCLUSION: This case-controlled study including a small number of patients, described postoperative biological changes among liver transplantations with steatosis in the graft.

Use of routine CT-SCANS to detect severe postoperative complications after pancreato-duodenectomy.

BACKGROUND: To evaluate the performance of CT-scans performed one week after pancreato-duodenectomy (PD) to detect severe postoperative complications requiring an invasive treatment. PATIENTS AND METHODS: This monocentric retrospective study was conducted on data collected between 2005 and 2013. Patients undergoing PD underwent CT-scan with IV contrast at the end of the first postoperative week. The results of the CT-scans were analyzed to evaluate the usefulness of this procedure. The main assessment criterion was the occurrence of type-III complication (or greater) according to the Dindo-Clavien classification. RESULTS: In total, 138 patients were included. The mortality rate was 2.2%. The postoperative complication rate was 57.2%. The pancreatic fistula rate was 19.6%; 46 patients (33.3%) presented with a severe complication. A total of 138 CT-scans were analyzed: 44 (31.8%) were abnormal, 94 (68.2%) were normal. Among patients with abnormal CT-scans, 17 (39%) presented with a severe complication requiring an invasive treatment. Among the 94 patients with normal CT-scans, 14 patients (15%) presented a severe postoperative complication. Evaluation of the performance of the CT-scans at the end of the first postoperative week found a sensitivity of 55%, a specificity of 75%, a positive predictive value of 39%, and a negative predictive value of 85%. CONCLUSION: Systematic CT-scans performed at the end of the first postoperative week do not effectively detect severe complications after PD and do not help to prevent them.

[Stereotactic hypofractionated radiation therapy as a bridge to transplantation for hepatocellular carcinoma: Case report of a complete pathological response and review of the literature]. / Place de la radiothérapie en conditions stéréotaxiques en traitement d'attente du carcinome hépatocellulaire avant transplantation hépatique : à propos d'un cas de réponse histologique complète sur explant et revue de la littérature.

Patients with hepatocellular carcinoma who are on liver transplant waiting list usually require local treatment to limit any risk of tumour growth. Historically percutaneous radiofrequency ablation or transarterial chemoembolization represented the major therapeutic alternatives. Depending on the size, or the topography of the lesion these two techniques may not be feasible. Radiation therapy under stereotactic conditions has recently emerged in the management of localized hepatocellular carcinoma as an alternative to the focused therapies performed to date. We herein report the case of a 43-year-old patient harbouring a complete histological response on explant after liver stereotactic irradiation and discuss its role in the management of hepatocellular carcinoma before liver transplantation.

Hepatitis C virus viral load after conversion from tacrolimus to cyclosporine in liver transplant patients: a pilot study.

UNLABELLED: We assessed whether conversion from tacrolimus (TAC) to cyclosporine (CsA) was associated with a reduction in hepatitis C virus (HCV) viral load among HCV-positive liver transplant (OLT) patients. PATIENTS AND METHODS: Nine OLT patients with recurrent HCV have TAC and prednisone immunosuppression. None received any HCV antiviral therapy. After the last intake of TAC, the patients underwent a 12-hour area under the curve (AUC(12)) measurement of both TAC and HCV viral loads. The next morning (D(0)) patients were given CsA (4 mg/kg bid). At the first intake of CsA and at 1 month (M(1)) later, the patients underwent AUC(12) for CsA and HCV viral loads. Biological data, including aspartate (AST) and alanine (ALT) aminotransferase, gamma-glutamyl transpeptidase (GGT), alkaline phosphatase (AP), and bilirubin levels, were collected during AUC(12), and at M(1) and M(3). RESULTS: With respect to liver enzymes (AST, ALT, GGT), there was no significant difference between D(0), M(1), and M(3). Conversely, there was a significant decrease in AP between D(0) and M(3) (P = .02), and a significant increase in total bilirubin between D(0) and M(1) (P = .04), and between D(0) and M(3) (P = .01). HCV viral load significantly increased by M(3) (P = .01). At no time (D(0), M(1)) was there any correlation between the AUC(12) of TAC or CsA, and between AUC(12) HCV viral load. CONCLUSION: This pilot study found no acute or chronic anti-HCV effects from CsA that were evident within 12 hours after CsA administrations or beyond 1 month of CsA therapy, respectively.

[Management of hilar cholangiocarcinoma]. / Prise en charge du cholangiocarcinome hilaire.

Hilar cholangiocarcinoma is a rare disease departing from the biliary convergence. It is primarily revealed by the onset of retention jaundice. Only 20%-30% of patients can undergo resection at diagnosis. The only chance for survival for these patients is R0 resection, which requires hepatectomy associated with resection of the common bile duct and pedicle lymph node removal, whatever the classification of the cholangiocarcinoma. No adjuvant treatment has been shown to be effective to date. Palliative treatment is most often based on implanting a biliary stent. Dynamic phototherapy may be beneficial in these situations. Improvements in survival for selected N0 hilar cholangiocarcinoma may be obtained with neoadjuvant treatment with radiochemotherapy followed by liver transplantation.
