RESUMEN

BACKGROUND: The extent of liver resection for tumours is limited by the expected functional reserve of the future liver remnant (FRL), so hypertrophy may be induced by portal vein embolization (PVE), taking 6 weeks or longer for growth. This study assessed the hypothesis that simultaneous embolization of portal and hepatic veins (PVE/HVE) accelerates hypertrophy and improves resectability. METHODS: All centres of the international DRAGON trials study collaborative were asked to provide data on patients who had PVE/HVE or PVE on 2016-2019 (more than 5 PVE/HVE procedures was a requirement). Liver volumetry was performed using OsiriX MD software. Multivariable analysis was performed for the endpoints of resectability rate, FLR hypertrophy and major complications using receiver operating characteristic (ROC) statistics, regression, and Kaplan-Meier analysis. RESULTS: In total, 39 patients had undergone PVE/HVE and 160 had PVE alone. The PVE/HVE group had better hypertrophy than the PVE group (59 versus 48 per cent respectively; P = 0.020) and resectability (90 versus 68 per cent; P = 0.007). Major complications (26 versus 34 per cent; P = 0.550) and 90-day mortality (3 versus 16 per cent respectively, P = 0.065) were comparable. Multivariable analysis confirmed that these effects were independent of confounders. CONCLUSION: PVE/HVE achieved better FLR hypertrophy and resectability than PVE in this collaborative experience.

RESUMEN

PURPOSE: Chemotherapy with or without radiotherapy is the standard in patients with initially nonmetastatic unresectable pancreatic cancer. Additional surgery is in discussion. The CONKO-007 multicenter randomized trial examines the value of radiotherapy. Our interim analysis showed a significant effect of surgery, which may be relevant to clinical practice. METHODS: One hundred eighty patients received induction chemotherapy (gemcitabine or FOLFIRINOX). Patients without tumor progression were randomized to either chemotherapy alone or to concurrent chemoradiotherapy. At the end of therapy, a panel of five independent pancreatic surgeons judged the resectability of the tumor. RESULTS: Following induction chemotherapy, 126/180 patients (70.0%) were randomized to further treatment. Following study treatment, 36/126 patients (28.5%) underwent surgery; (R0: 25/126 [19.8%]; R1/R2/Rx [n = 11/126; 6.1%]). Disease-free survival (DFS) and overall survival (OS) were significantly better for patients with R0 resected tumors (median DFS and OS: 16.6 months and 26.5 months, respectively) than for nonoperated patients (median DFS and OS: 11.9 months and 16.5 months, respectively; p = 0.003). In the 25 patients with R0 resected tumors before treatment, only 6/113 (5.3%) of the recommendations of the panel surgeons recommended R0 resectability, compared with 17/48 (35.4%) after treatment (p < 0.001). CONCLUSION: Tumor resectability of pancreatic cancer staged as unresectable at primary diagnosis should be reassessed after neoadjuvant treatment. The patient should undergo surgery if a resectability is reached, as this significantly improves their prognosis.

RESUMEN

BACKGROUND: CONKO-006 was designed for patients with pancreatic adenocarcinoma with postsurgical R1 residual status to evaluate the efficacy and safety of the combination of gemcitabine and sorafenib (GemSorafenib) compared with those of gemcitabine + placebo (GemP) for 12 cycles. PATIENTS AND METHODS: This randomised, double-blind, placebo-controlled, multicenter study was planned to detect an improvement in recurrence-free survival (RFS) from 42% to 60% after 18 months. Secondary objectives were overall survival (OS), safety and duration of treatment. RESULTS: 122 patients were included between 02/2008 and 09/2013; 57 were randomised to GemSorafenib and 65 to GemP. Patient characteristics were wellbalanced (GemSorafenib/GemP) in terms of median age (63/63 years), tumour size (T3/T4: 97/97%), and nodal positivity (86/85%). Grade 3/4 toxicities comprised diarrhoea (GemSorafenib: 12%; GemP: 2%), elevated gamma-glutamyl transferase (GGT) (19%; 9%), fatigue (5%; 2%) and hypertension (5%; 2%), as well as neutropenia (18%; 25%) and thrombocytopenia (9%; 2%). By August 2017, 118 (97%) RFS event had occurred. There were no difference in RFS (median GemSorafenib: 8.5 versus GemP: 9.4 months; p = 0.730) nor OS (median GemSorafenib: 17.6 versus GemP: 17.5 months; p = 0.481). Landmark analyses suggest that patients who received more than six cycles of postoperative chemotherapy had significantly longer OS (p = 0.021). CONCLUSION: CONKO-006 is the first randomised clinical trial to include exclusively patients with PDAC with postsurgical R1 status thus far. Sorafenib added to gemcitabine did neither improve RFS nor OS. However, postoperative treatment exceeding six months seemed to prolong survival and should be further investigated in these high-risk patients.

RESUMEN

Solid organ transplantation is frequently carried out in this society. Under these circumstances the basic principles are altruistic organ donation and abidance by the law, which are regulated by the German Transplantation Act and by directives of the Federal Medical Council from which process instructions of the German Organ Transplantation Foundation are derived. The organ allocation is carried out by the Eurotransplant International Foundation (ET) located in Leiden, the Netherlands. Organ procurement is an essential component of the process of organ donation. This article highlights the procedure for harvesting of abdominal organs and also nonsurgical issues in the process of organ donation.

RESUMEN

BACKGROUND: The incidence of lymphatic complications after kidney transplantation varies considerably in the literature. This is partly because a universally accepted definition has not been established. This study aimed to propose an acceptable definition and severity grading system for lymphatic complications based on their management strategy. METHODS: Relevant literature published in MEDLINE and Web of Science was searched systematically. A consensus for definition and a severity grading was then sought between 20 high-volume transplant centres. RESULTS: Lymphorrhoea/lymphocele was defined in 32 of 87 included studies. Sixty-three articles explained how lymphatic complications were managed, but none graded their severity. The proposed definition of lymphorrhoea was leakage of more than 50 ml fluid (not urine, blood or pus) per day from the drain, or the drain site after removal of the drain, for more than 1 week after kidney transplantation. The proposed definition of lymphocele was a fluid collection of any size near to the transplanted kidney, after urinoma, haematoma and abscess have been excluded. Grade A lymphatic complications have a minor and/or non-invasive impact on the clinical management of the patient; grade B complications require non-surgical intervention; and grade C complications require invasive surgical intervention. CONCLUSION: A clear definition and severity grading for lymphatic complications after kidney transplantation was agreed. The proposed definitions should allow better comparisons between studies.


ANTECEDENTES: La incidencia de complicaciones linfáticas tras el trasplante renal (post-kidney-transplantation lymphatic, PKTL) varía considerablemente en la literatura. Esto se debe en parte a que no se ha establecido una definición universalmente aceptada. Este estudio tuvo como objetivo proponer una definición aceptable para las complicaciones PKTL y un sistema de clasificación de la gravedad basado en la estrategia de tratamiento. MÉTODOS: Se realizó una búsqueda sistemática de la literatura relevante en MEDLINE y Web of Science. Se logró un consenso para la definición y la clasificación de gravedad de las PKTL entre veinte centros de trasplante de alto volumen. RESULTADOS: En 32 de los 87 estudios incluidos se definía la linforrea/linfocele. Sesenta y tres artículos describían como se trataban las PKTL, pero ninguno calificó la gravedad de las mismas. La definición propuesta para la linforrea fue la de un débito diario superior a 50 ml de líquido (no orina, sangre o pus) a través del drenaje o del orificio cutáneo tras su retirada, más allá del 7º día postoperatorio del trasplante renal. La definición propuesta para linfocele fue la de una colección de líquido de tamaño variable adyacente al riñón trasplantado, tras haber descartado un urinoma, hematoma o absceso. Las PKTL de grado A fueron aquellas con escaso impacto o que no requirieron tratamiento invasivo; las PKTL de grado B fueron aquellas que precisaron intervención no quirúrgica y las PKTL de grado C aquellas en que fue necesaria la reintervención quirúrgica. CONCLUSIÓN: Se propone una definición clara y una clasificación de gravedad basada en la estrategia de tratamiento de las PKTLs. La definición propuesta y el sistema de calificación en 3 grados son razonables, sencillos y fáciles de comprender, y servirán para estandarizar los resultados de las PKTL y facilitar las comparaciones entre los diferentes estudios.

RESUMEN

BACKGROUND: One critical step in the therapy of patients with localized pancreatic cancer is the determination of local resectability. The decision between primary surgery versus upfront local or systemic cancer therapy seems especially to differ between pancreatic cancer centers. In our cohort study, we analyzed the independent judgement of resectability of five experienced high volume pancreatic surgeons in 200 consecutive patients with borderline resectable or locally advanced pancreatic cancer. METHODS: Pretherapeutic CT or MRI scans of 200 consecutive patients with borderline resectable or locally advanced pancreatic cancer were evaluated by 5 independent pancreatic surgeons. Resectability and the degree of abutment of the tumor to the venous and arterial structures adjacent to the pancreas were reported. Interrater reliability and dispersion indices were compared. RESULTS: One hundred ninety-four CT scans and 6 MRI scans were evaluated and all parameters were evaluated by all surgeons in 133 (66.5%) cases. Low agreement was observed for tumor infiltration of venous structures (κ = 0.265 and κ = 0.285) while good agreement was achieved for the abutment of the tumor to arterial structures (interrater reliability celiac trunk κ = 0.708 P < 0.001). In patients with vascular tumor contact indicating locally advanced disease, surgeons highly agreed on unresectability, but in patients with vascular tumor abutment consistent with borderline resectable disease, the judgement of resectability was less uniform (dispersion index locally advanced vs. borderline resectable p < 0.05). CONCLUSION: Excellent agreement between surgeons exists in determining the presence of arterial abutment and locally advanced pancreatic cancer. The determination of resectability in borderline resectable patients is influenced by additional subjective factors. TRIAL REGISTRATION: EudraCT:2009-014476-21 (2013-02-22) and NCT01827553 (2013-04-09).

RESUMEN

BACKGROUND: Secondary resection of initially unresectable colorectal cancer liver metastases (CRLM) can prolong survival. The added value of selective internal radiotherapy (SIRT) to downsize lesions for resection is not known. This study evaluated the change in technical resectability of CRLM with the addition of SIRT to FOLFOX-based chemotherapy. METHODS: Baseline and follow-up hepatic imaging of patients who received modified FOLFOX (mFOLFOX6: fluorouracil, leucovorin, oxaliplatin) chemotherapy with or without bevacizumab (control arm) versus mFOLFOX6 (with or without bevacizumab) plus SIRT using yttrium-90 resin microspheres (SIRT arm) in the phase III SIRFLOX trial were reviewed by three or five (of 14) expert hepatopancreatobiliary surgeons for resectability. Reviewers were blinded to one another, treatment assignment, extrahepatic disease status, and information on clinical and scanning time points. Technical resectability was defined as at least 60 per cent of reviewers (3 of 5, or 2 of 3) assessing a patient's liver metastases as surgically removable. RESULTS: Some 472 patients were evaluable (SIRT, 244; control, 228). There was no significant baseline difference in the proportion of technically resectable liver metastases between SIRT (29, 11·9 per cent) and control (25, 11·0 per cent) arms (P = 0·775). At follow-up, significantly more patients in both arms were deemed technically resectable compared with baseline: 159 of 472 (33·7 per cent) versus 54 of 472 (11·4 per cent) respectively (P = 0·001). More patients were resectable in the SIRT than in the control arm: 93 of 244 (38·1 per cent) versus 66 of 228 (28·9 per cent) respectively (P < 0·001). CONCLUSION: Adding SIRT to chemotherapy may improve the resectability of unresectable CRLM.


ANTECEDENTES: La resección secundaria de metástasis hepáticas de cáncer colorrectal (colorectal cancer liver metastases, CRLM) inicialmente irresecables puede prolongar la supervivencia. Se desconoce el valor añadido de la radioterapia interna selectiva (selective internal radiation therapy, SIRT). Este estudio evaluó el cambio en la resecabilidad técnica de las CRLM secundario a la adición de SIRT a una quimioterapia tipo FOLFOX. MÉTODOS: Las pruebas de radioimagen basales y durante el seguimiento de pacientes tratados con un régimen FOLFOX modificado (mFOLFOX6: fluorouracilo, leucovorina, oxaliplatino) ± bevacizumab (grupo control) versus mFOLFOX6 (± bevacizumab) más SIRT usando microesferas de resina de yttrium-90, en el ensayo de fase III SIRFLOX, fueron revisadas por 3-5 (de 14) cirujanos expertos hepatobiliares para determinar la resecabilidad. Los expertos efectuaron la revisión de forma ciega unos respecto a otros en relación con la asignación al tratamiento, estado de la enfermedad extra-hepática y situación clínica en el momento del estudio radiológico. La resecabilidad técnica se definió como ≥ 60% de revisores evaluando las metástasis del paciente como quirúrgicamente resecables. RESULTADOS: Fueron evaluables un total de 472 pacientes (control, n = 228; SIRT, n = 244). No hubo diferencias significativas basales en la proporción de metástasis hepáticas técnicamente resecables entre SIRT (29/244; 11,9%) y el grupo control (25/228; 11,0%: P = 0,775). Durante el seguimiento y en ambos brazos de tratamiento, un número significativamente mayor de pacientes se consideraron técnicamente resecables en comparación con la situación basal (54/472 (11,4%) basal y 159/472 (33,7%) al seguimiento). Hubo más pacientes resecables en el grupo SIRT que en el control (93/244 (38,1%) y 66/228 (28,9%); P < 0,001, respectivamente). CONCLUSIÓN: La adición de SIRT a la quimioterapia puede mejorar la resecabilidad de las CRLM irresecables.

RESUMEN

BACKGROUND: Mortality rates after liver surgery are not well documented in Germany. More than 1000 hospitals offer liver resection, but there is no central regulation of infrastructure requirements or outcome quality. METHODS: Hospital mortality rates after liver resection were analysed using the standardized hospital discharge data (Diagnosis-Related Groups, ICD-10 and German operations and procedure key codes) provided by the Research Data Centre of the Federal Statistical Office and Statistical Offices of the Länder in Wiesbaden, Germany. RESULTS: A total of 110 332 liver procedures carried out between 2010 and 2015 were identified. The overall hospital mortality rate for all resections was 5·8 per cent. The mortality rate among 17 574 major hepatic procedures was 10·4 per cent. Patients who had surgery for colorectal liver metastases (CRLMs) had the lowest mortality rate among those with malignancy (5·5 per cent), followed by patients with gallbladder cancer (7·1 per cent), hepatocellular carcinoma (9·3 per cent) and intrahepatic cholangiocarcinoma (11·0 per cent). Patients with extrahepatic cholangiocarcinoma had the highest mortality rate (14·6 per cent). The mortality rate for extended hepatectomy was 16·2 per cent and the need for a biliodigestive anastomosis increased this to 25·5 per cent. Failure to rescue after complications led to mortality rates of more than 30 per cent in some subgroups. There was a significant volume-outcome relationship for CRLM surgery in very high-volume centres (mean 26-60 major resections for CRLMs per year). The mortality rate was 4·6 per cent in very high-volume centres compared with 7·5 per cent in very low-volume hospitals (odds ratio 0·60, 95 per cent c.i. 0·42 to 0·77; P < 0·001). CONCLUSION: This analysis of outcome data after liver resection in Germany suggests that hospital mortality remains high. There should be more focused research to understand, improve or justify factors leading to this result, and consideration of centralization of liver surgery.


ANTECEDENTES: En Alemania, los datos de mortalidad después de la cirugía no están bien documentados. En más de 1.000 hospitales se realizan resecciones hepáticas, pero no existe una regulación central de los prerrequisitos estructurales necesarios y de la calidad de los resultados. MÉTODOS: Las tasas de mortalidad hospitalaria relacionadas con las resecciones hepáticas se analizaron utilizando los datos estandarizados del alta hospitalaria (Diagnóstico de grupos relacionados, DRG), la clasificación internacional de enfermedades 10 (ICD10) y la clave de procedimientos y operaciones (códigos OPS) proporcionados por el RDC de la Oficina Federal de Estadística y Oficinas de Estadística de Länder en Wiesbaden, Alemania. RESULTADOS: Se identificaron un total de 110.332 procedimientos hepáticos (de 2010 a 2015). La tasa global de mortalidad hospitalaria para todas las resecciones fue del 5,8%. Las resecciones hepáticas mayores (n = 15.333) presentaron una mortalidad del 10,4%. Los pacientes con metástasis hepáticas colorrectales (colorectal liver metastases, CRLM) tuvieron la mortalidad más baja de entre los pacientes con neoplasias malignas (5,5%), seguidos de los pacientes con cáncer de vesícula biliar (7,1%), colangiocarcinoma intrahepático (intrahepatic colangiocarcinoma, iCC) (11,0%) y carcinoma hepatocelular (hepatocellular carcinoma, HCC) (9,3%). Los pacientes con colangiocarcinoma extrahepático (extrahepatic cholangiocarcinoma, eCC) presentaron la mortalidad más alta (14,6%). Las hepatectomías extendidas (16,2%) y la necesidad de una anastomosis biliodigestiva (biliodigestive anastomosis, BDA) aumentaron la mortalidad a un 25,5%. La falta de solución de algunas complicaciones llevó a tasas de mortalidad de más del 30% en algunos subgrupos. Hubo una relación significativa volumen-resultado para las CRLM en centros de alto volumen (25,3 a 59,7 resecciones mayores/año; razón de oportunidades, odds ratio, OR 0,60, i.c. del 95%: 0,42-0,77; P < 0,001), lo que resultó en una disminución en las tasas de mortalidad de 7,5/6,4/7,5/6,5% a 4,6%. CONCLUSIÓN: El análisis de los resultados después de la resección hepática en Alemania muestra una alta mortalidad hospitalaria inesperada. Este análisis indica la necesidad de efectuar una investigación más específica para comprender, mejorar o justificar los factores que determinan estos hallazgos.

RESUMEN

Diagnostic guidelines for thyroid nodules focus on malignancy risk assessment to avoid unnecessary diagnostic operations. These guidelines recommend a combination of tests in form of a diagnostic algorithm. The present study analyzed the recommended algorithm and its implementation by different medical professionals. Preoperative diagnostic procedures, laboratory tests and histopathological findings of patients who underwent thyroid surgery between 2006 and 2013 were analyzed. The results were stratified by the assignation by specialized endocrinologists (ENP), general practitioners (GP) or Goethe-University Hospital Frankfurt (UKF). 677 patients were enrolled, of these 62% were assigned by UKF, 18.5% by an ENP and 19.5% by a GP. Ultrasonography rate was significantly higher in UKF (97.6%) compared to patients assigned by GP (90.9%, p<0.0001). Rates for fine-needle aspiration cytology ranged between 47.6% in UKF and 23.2% in ENP (p<0.0001). In over 93% of the patients an analysis of thyroid-stimulating hormone and triiodothyronine/thyroxin was realized. The overall malignancy rate was 11.82%. The malignancy rate was significantly higher if a FNA biopsy was performed (16.35 vs. 8.94%; p=0.0048). A higher malignancy rate could only be seen if the preoperative diagnostic workup included FNA. Besides this, the grade of algorithm adherence showed no effect on the malignancy rate.

RESUMEN

INTRODUCTION: Diverticulosis is a relevant disease in Germany with a prevalence of over 60 % in patients aged ≥70 years. The S2k guidelines for the treatment of diverticulosis were recently published. Systematic epidemiological data on treatment modalities do not exist. METHODS: Analysis of in-hospital treatment modalities for diverticulosis based on data from the Federal Office of Statistics. RESULTS: Approximately 130,000 inpatient cases of diverticulosis are treated in Germany per year. Approximately 25 % undergo surgery and of these slightly under 50 % (12,000 procedures) are carried out by laparoscopy. The complication rates are 18 % in a best case scenario and up to 85 % in a worst case scenario. A stage-adjusted classification of treatment modalities based on data from the Federal Office of Statistics is currently practically impossible. CONCLUSION: To enable stage-adjusted epidemiological analysis of diverticulosis, a standardized and transparent documentation system enabling systematic analysis is necessary, which does not currently exist (e. g. ICD 10 coding); moreover, information on conservative and interventional treatment options are not included in the operations and procedures key (OPS) coding system.

RESUMEN

AIM: Colorectal resection is frequently performed during cytoreductive surgery for gynaecological malignancy. The aim of this study was to assess the safety of colorectal anastomosis, and especially low rectal anastomosis, in the absence of a protective stoma in patients with gynaecological cancer and peritoneal metastasis. METHOD: Patient data were retrospectively collected from a database for gynaecological cancer procedures carried out between January 2013 and July 2015. All patients who underwent a colorectal resection during cytoreduction were included in the study. The primary outcome was anastomotic leakage in the presence or absence of a diverting stoma. Secondary outcome parameters were complications and reoperations. RESULTS: In the period of study, 43 major colorectal procedures were performed on 37 women. The most common colorectal procedure was low rectal resection (n = 22; 59%) followed by anterior rectal resection (n = 7; 19%) and sigmoid resection (n = 4; 11%). Five (14%) patients underwent Hartmann's procedure. In three (8%) patients, a diverting loop ileostomy was created. CONCLUSION: Low rectal resection during debulking procedures for gynaecological cancers with peritoneal carcinomatosis can safely be performed by an experienced surgeon without a diverting stoma.

RESUMEN

INTRODUCTION: In current literature, the participation of residents in surgical procedures is discussed as a negative outcome factor, particularly due to an increase of postoperative complications. This study investigated whether minor proctologic surgery with resident participation has a higher rate of postoperative complications. PATIENTS AND METHODS: All patients who underwent an elective Milligan-Morgan hemorrhoidectomy or a resection of pilonidal sinus with rotational flap closure between January 2007 and December 2013 where included in a retrospective database. Primary outcome measure was postoperative complications rate with and without resident participation. RESULTS: Forty-two (6 females: 36 males) patients underwent resection of pilonidal sinus and 61 (17 females: 44 males) patients received a hemorrhoidectomy. Twenty-two patients with pilonidal sinus and 26 patients with hemorrhoids were operated by residents. There were no differences in patient demographics. Residents need significantly more time to perform a pilonidal sinus resection (54min vs. 34.5min; P = 0.004). For hemorrhoidectomy, there were no significant differences in operative time (24min vs. 23.5min; P = 0.656). There were no significant differences in the resident and the consultant group, neither in hemorrhoidectomy nor in pilonidal sinus resection regarding readmission or outpatient visits. In the group of patients with pilonidal sinus resections, 3 patients developed a recurrence, leading to a recurrence rate of 7.1% without significant differences between the two groups (0 vs. 3; P = 0.09). CONCLUSION: The participation of residents in proctologic procedures is not associated with higher postoperative complication rates. Residents should be exposed to proctology procedures on a regular basis, even though the operative time will be prolonged.

RESUMEN

CONTEXT: The intravenously administered selective α1 antagonist urapidil represents an alternative to phenoxybenzamine in the preoperative treatment of pheochromocytoma patients. OBJECTIVE: The aim of the study was to investigate the blood pressure changes in pheochromocytoma patients with urapidil pretreatment with special regards to the need for interventions in order to estimate the safety of this treatment in a normal ward setting. DESIGN: The medical records of all patients who underwent adrenalectomy for PCC were reviewed retrospectively. Systolic blood pressure values >180mmHg were defined as hypertensive episodes and systolic blood pressure values < 50mmHg as hypotensive episodes. Episodes of blood pressure instabilities were considered significant and recorded as intervention if they led to a direct action. RESULTS: Twenty consecutive patients who received urapidil pretreatment were enrolled in this retrospective study. Preoperatively, a median of 9 blood pressure measurements per day have been performed on the ward. A total of 2 episodes of hypertension occurred, and 1 episode of hypotension has been recorded. In the period from 25-72 hours postoperatively the median number of blood pressure measurements was 5 per 24 hours. The blood pressure deviations led to a total of 3 interventions for hypertension in 1 (5%) patients and 5 interventions for hypotension in 3 (15%) patients. All interventions could be managed on the normal ward, without the need to transfer the patient to an ICU. CONCLUSIONS: Intravenous urapidil can safely be administered on a normal ward without putting patients at risk. Intensive monitoring beyond 24 hours postoperatively was not necessary, the blood pressure measurements during the shift on a normal ward were sufficient for maintaining patients' safety.

RESUMEN

This study was a retrospective analysis of the European Liver Transplant Registry (ELTR) performed to compare long-term outcomes with prolonged-release tacrolimus versus tacrolimus BD in liver transplantation (January 2008-December 2012). Clinical efficacy measures included univariate and multivariate analyses of risk factors influencing graft and patient survival at 3 years posttransplant. Efficacy measures were repeated using propensity score-matching for baseline demographics. Patients with <1 month of follow-up were excluded from the analyses. In total, 4367 patients (prolonged-release tacrolimus: n = 528; BD: n = 3839) from 21 European centers were included. Tacrolimus BD treatment was significantly associated with inferior graft (risk ratio: 1.81; p = 0.001) and patient survival (risk ratio: 1.72; p = 0.004) in multivariate analyses. Similar analyses performed on the propensity score-matched patients confirmed the significant survival advantages observed in the prolonged-release tacrolimus- versus tacrolimus BD-treated group. This large retrospective analysis from the ELTR identified significant improvements in long-term graft and patient survival in patients treated with prolonged-release tacrolimus versus tacrolimus BD in primary liver transplant recipients over 3 years of treatment. However, as with any retrospective registry evaluation, there are a number of limitations that should be considered when interpreting these data.

RESUMEN

UNLABELLED: DIAMOND: multicenter, 24-week, randomized trial investigating the effect of different once-daily, prolonged-release tacrolimus dosing regimens on renal function after de novo liver transplantation. Arm 1: prolonged-release tacrolimus (initial dose 0.2mg/kg/day); Arm 2: prolonged-release tacrolimus (0.15-0.175mg/kg/day) plus basiliximab; Arm 3: prolonged-release tacrolimus (0.2mg/kg/day delayed until Day 5) plus basiliximab. All patients received MMF plus a bolus of corticosteroid (no maintenance steroids). PRIMARY ENDPOINT: eGFR (MDRD4) at Week 24. Secondary endpoints: composite efficacy failure, BCAR and AEs. Baseline characteristics were comparable. Tacrolimus trough levels were readily achieved posttransplant; initially lower in Arm 2 versus 1 with delayed initiation in Arm 3. eGFR (MDRD4) was higher in Arms 2 and 3 versus 1 (p = 0.001, p = 0.047). Kaplan-Meier estimates of composite efficacy failure-free survival were 72.0%, 77.6%, 73.9% in Arms 1-3. BCAR incidence was significantly lower in Arm 2 versus 1 and 3 (p = 0.016, p = 0.039). AEs were comparable. Prolonged-release tacrolimus (0.15-0.175mg/kg/day) immediately posttransplant plus basiliximab and MMF (without maintenance corticosteroids) was associated with lower tacrolimus exposure, and significantly reduced renal function impairment and BCAR incidence versus prolonged-release tacrolimus (0.2mg/kg/day) administered immediately posttransplant. Delayed higher-dose prolonged-release tacrolimus initiation significantly reduced renal function impairment compared with immediate posttransplant administration, but BCAR incidence was comparable.

RESUMEN

BACKGROUND: The International Study Group of Liver Surgery (ISGLS) defined posthepatectomy liver failure as pathological values for the international normalized ratio (INR) and bilirubin 5 days after liver resection. The occurrence of biliary leakage was defined as a drainage bilirubin to serum bilirubin ratio > 3 at day 3 or later after resection or interventional surgical revision due to biliary peritonitis. A confirmatory explorative analysis was carried out. PATIENTS AND METHODS: The study involved an evaluation of primary liver resection from the years 2009 and 2010. Primary endpoints were the incidence of posthepatectomy liver failure and biliary leakage in accordance with the ISGLS definition. Secondary endpoints were complications and 90-day mortality. Results are displayed as median values (minimum and maximum). RESULTS: A total of 214 liver resections were included from the years 2009 and 2010. Patients were an average of 61.5 years old (min. 18, max. 83 years). The incidence of liver failure was 7.4 % (16 out of 214) and fatal in 7 patients. In 31 % (65 out of 214) a biliary leakage occurred, 14 (23 %) patients developed a type B, 1 patient(5 %) a type C leakage and 50 leakages were clinically inapparent. The incidence of clinically relevant biliary leakages was 7 % (15 out of 214). The sensitivity of the definition was 100 % and the specificity 75 %. The incidence of Dindo-Calvien complications > 3b was 10.2 %, of sepsis 5.6 % and the 90-day mortality was 6.5 %. Multivariate analysis did not reveal independent predictive factors for biliary leakage or liver failure. CONCLUSION: The definition for posthepatectomy liver failure was found to be valid in this cohort. The incidence of postoperative biliary leakage is over-estimated with the current definition and delivers a large number of false positive results without clinical relevance.
