Safety of intra-operative blood salvage during liver transplantation in patients with hepatocellular carcinoma, a propensity score-matched survival analysis.

Intra-operative blood salvage (IBS) reduces the use of allogeneic blood transfusion. However, safety of IBS during liver transplantation (LT) for hepatocellular carcinoma (HCC) is questioned due to fear for dissemination of circulating malignant cells. This study aims to assess safety of IBS. HCC patients who underwent LT from January 2006 through December 2019 were included. Patients in whom IBS was used were propensity score matched (1:1) to control patients. Disease-free survival and time to HCC recurrence were assessed with Cox regression models and competing risk models. IBS was used in 192/378 HCC LT recipients, and 127 patients were propensity score matched. Cumulative disease-free survival at 12 and 60 months was 85% and 63% for the IBS group versus 90% and 68% for the no-IBS group. Use of IBS was not associated with impaired disease-free survival (HR 1.07, 95%CI: 0.65-1.76, P = 0.800) nor with increased HCC recurrence (Cause-specific cox model: HR 0.79, 95%CI: 0.36-1.73, P = 0.549, Fine and Gray model: HR: 0.79, 95%CI 0.40-1.57, P = 0.50). In conclusion, IBS during LT did not increase the risk for HCC recurrence. IBS is a safe procedure in HCC LT recipients to reduce the need for allogenic blood transfusion.

Neoplasias quísticas hepáticas: experiencia en un único centro y revisión de la literatura / Cystic liver neoplams: A single centre experience and literature review

INTRODUCCIÓN: La neoplasia quística hepática es una neoplasia poco frecuente, que representa aproximadamente el 5% de las lesiones quísticas del hígado. El diagnóstico preoperatorio es difícil y puede causar confusión. El objetivo del estudio es analizar una serie de casos operados en nuestro centro con diagnóstico anatomopatológico de neoplasia quística hepática y describir la sintomatología, diagnóstico y tratamiento de acuerdo con la actual clasificación. MÉTODOS: Se realizó un análisis retrospectivo de todas las neoplasias quísticas hepáticas operadas entre enero de 2000 y diciembre de 2019. El estudio se basó en los informes de anatomía patológica ya existentes. Los casos anteriores al 2010 fueron reclasificados según la clasificación de la OMS del año 2010. RESULTADOS: La muestra total del estudio resultó en 10 pacientes: 6 fueron neoplasias mucinosas quísticas hepáticas y 4 neoplasias papilares intraductales biliares. La mayoría de los pacientes fueron mujeres (8/10) y la edad media fue de 47 años. En cuanto al tratamiento, hubo 3 hepatectomías y 7 enucleaciones. En ningún caso se realizó una biopsia intraoperatoria de los márgenes quirúrgicos. En un caso se observó atipia celular variable con zonas de adenocarcinoma, por lo que el paciente recibió quimioterapia adyuvante con taxol y carboplatino. En todos los casos los márgenes de resección fueron negativos. CONCLUSIÓN: Las neoplasias quísticas hepáticas son tumores poco frecuentes, que plantean un dilema en el diagnóstico diferencial, por lo que, ante la sospecha radiológica, el tratamiento de elección debería ser la resección completa del tumor para evitar su malignización y la recidiva

INTRODUCTION: The hepatic cystic tumour is a very rare neoplasm, representing about 5% of all cystic liver neoplasms. The preoperative diagnosis is difficult and can lead to confusion. The aim of this study is to analyze a number of cases operated at our centre with an histologic diagnosis of liver cystic neoplasms and also to describe the sintomathology, diagnosis and management as per the recent classification. METHODS: A retrospective analysis was performed including all the cystic liver neoplasms operated between January 2000 and December 2019. The study was performed based on the pre-existing pathology archives. The 2010 previous cases were reclassified following the new 2010 OMS classification. RESULTS: The study sample was of 10 patients, identifying 6 of them as mucinous cystic liver neoplasms, and the other 4 as intraductal papillary biliary neoplasms. The majority of the patients were women (8/10) and the median age was 47 years. Regarding the treatment, 3 hepatectomy and 7 enucleations were performed. Frozen section intraoperatively was not required in any case. In one case, variable cellular atypia with areas of adenocarcinoma was observed, and the patient received neoadyuvant chemotherapy with taxol and carboplatin. In all cases the resection margins were negative. CONCLUSION: Cystic liver neoplasms are infrequent tumours with a difficult differential diagnosis. Therefore, with a high radiological suspicious, the treatment should be a complete resection to avoid recurrences and malignancies

Umbilical metastasis of a pancreatic origin: Sister Mary Joseph's nodule.

An 84-year-old male patient presented with an umbilical mass. Upon examination, he had an umbilical lesion of approx. 2 cm that was nodular and painful on palpation. The abdominal CT showed a soft tissue mass of 20 x 22 mm in the umbilical subcutaneous tissue, associated with inflammatory changes. In addition, a hypodense tumor of 3.6 x 3.6 x 3.8 cm was seen located in the pancreatic tail, infiltrating the splenic hylum. Bloodwork revealed the following: haemoglobin 7.9 mg/dl, platelets: 175 x 100 /µl, prothrombin activity: 81%, INR: 1.13, Ca 19.9: 4289 U / ml, CEA: 4.38 ng / ml. The histopathological study of the umbilical lesion showed an adenocarcinoma with a moderately differentiated primary pancreatic origin, compatible with an umbilical metastasis of pancreatic cancer.

Uso de la octreótida en ascitis refractaria después de un trasplante hepático / Using octreotide for refractory ascites after liver transplantation

La ascitis refractaria es una patología que se asocia con una disminución de la supervivencia del paciente y un empeoramiento de su calidad de vida. Una de las causas de la misma después de un trasplante hepático es el hiperaflujo portal. Presentamos el caso de una paciente con ascitis refractaria postrasplante hepático a la cual se le realiza como tratamiento una embolización esplénica. La ascitis persiste a pesar de la embolización por repermeabilización del bazo por los vasos gástricos cortos, siendo técnicamente imposible una nueva embolización. Se decide iniciar tratamiento con octreótida, un octapéptido análogo de la somatostina, con base en su fisiopatología al producir vasoconstricción esplácnica, lo que reduce el flujo y la presión venosa portal. A los cuatro meses del inicio del tratamiento con octreótida, la paciente presenta una buena situación clínica y sin ascitis

Refractory ascites is a condition associated with a reduced survival and a poorer quality of life. Portal hyperflow after liver transplantation is one of the main causes. We report the case of a female patient with refractory ascites after liver transplantation who was treated with splenic embolization. Ascites persisted despite embolization due to splenic revascularization by short gastric vessels and repeat embolization was technically unfeasible. Based on pathophysiology data, she was treated with octreotide, a somatostatin octapeptide analog, which resulted in splanchnic vasoconstriction and a reduction of the portal flow and venous pressure. After four months of treatment with octreotide, the patient had a good clinical status without ascites

Complicaciones de la quimioembolización transarterial (QETA) en el tratamiento de los tumores hepáticos / Complications of transarterial chemoembolization (TACE) in the treatment of liver tumors

INTRODUCCIÓN: La quimioembolización transarterial (QETA) es considerada una opción terapéutica utilizada en el tratamiento del carcinoma hepatocelular y de las metástasis hepáticas secundarias del carcinoma colorrectal, tumores neuroendocrinos y melanoma ocular. Aunque es un procedimiento seguro, no está exento de complicaciones, siendo la más frecuente la colecistitis aguda. Otras complicaciones descritas son el tromboembolismo pulmonar, el absceso hepático, lesiones de la mucosa gastrointestinal, lesiones de la vía biliar, etc. El objetivo principal del estudio es revisar y describir las complicaciones derivadas de la QETA en el tratamiento de los tumores hepáticos. MÉTODOS: Se ha realizado un análisis retrospectivo de todas las QETA practicadas en nuestro centro entre enero de 2013 y diciembre de 2016. En dicho periodo se realizaron 322 QETA en 196 pacientes. RESULTADOS: Del total de procedimientos, 258 (80%) fueron realizados en hombres y 64 (20%) en mujeres. Además, la edad media de los pacientes fue de 66,5años. Las complicaciones mayores derivadas de la QETA fueron descompensación edemo-ascítica (6 casos), colecistitis aguda (4), pancreatitis aguda (3), rotura hepática (1), absceso hepático (1) y deterioro de la función renal (1). Además, el síndrome postembolización se objetivó en 71 (22%) casos. En el análisis multivariante se observó que el antecedente cardiovascular (OR: 4,5; IC95%: 1,2-17; p = 0,025) es un factor de riesgo para el desarrollo de complicaciones post-QETA. CONCLUSIONES: Las complicaciones derivadas de la QETA son poco frecuentes y con una baja incidencia de mortalidad

INTRODUCTION: Transarterial chemoembolization (TACE) is considered a therapeutic option. It is mostly used in hepatocellular carcinoma or liver colorectal, neuroendocrine or melanoma metastases. Although it is considered a safe procedure, TACE presents complications, such as acute cholecystitis, which is the most common. Other procedure-related complications include pulmonary embolism, hepatic abscess, bile duct injury, gastric mucosa injury and, less frequently, acute pancreatitis. The aim of this study is to review the complications following TACE for liver tumors. METHODS: We performed a retrospective study including all the TACE procedures performed in a single center during the period between January 2013 and December 2016. RESULTS: Out of the 196 patients with liver tumors who had undergone 322 TACE, 258 (80%) were male and 64 (20%) were female. Mean patient age was 66.5years. Major complications after chemoembolization included: decompensation with edema/ascites (6 patients), acute cholecystitis (4), acute pancreatitis (3), liver rupture (1), liver abscess (1) and renal failure (1). Postembolization syndrome appeared in 71 (20%) patients. On multivariate analysis, it was observed that concomitant cardiovascular disease (OR: 4.5; 95%CI: 1.2-17; P=.025) is a risk factor for the development of complications. CONCLUSIONS: TACE is a safe and effective procedure for liver tumor treatment. The majority of the complications are rare and present a low incidence of mortality

Análisis retrospectivo en pacientes con cáncer de vesícula biliar: tratamiento quirúrgico y supervivencia en función del estadio tumoral / A retrospective analysis of patients with gallbladder cancer: surgical treatment and survival according to tumor stage

Introducción: el cáncer de vesícula biliar es la neoplasia más frecuente de vías biliares y el sexto de los tumores del aparato digestivo, presentando un pronóstico ominoso, con una supervivencia a cinco años alrededor del 5%. Suele diagnosticarse de forma tardía y la única posibilidad de curación es la resección quirúrgica. Métodos: se realizó un estudio retrospectivo en el cual fueron analizados 92 pacientes (64 mujeres y 28 hombres) diagnosticados por anatomía patológica con cáncer de vesícula entre enero de 2000 y enero de 2016. Resultados: La edad media de la serie fue 72 ± 11 años. Los síntomas de los pacientes al ingreso fueron: dolor abdominal (78%), anorexia (77%), náuseas (76%) e ictericia (45%). La cirugía se indicó en los 92 (100%) pacientes y se realizó una resección con intención curativa en 59 (64%) de ellos. Entre los procedimientos quirúrgicos realizados en la cirugía inicial, la colecistectomía simple se efectuó en 69 (75%) y la colecistectomía extendida, en once (11%) pacientes. La cirugía de rescate se realizó en 15 pacientes después del hallazgo tumoral en la pieza de colecistectomía, realizando una resección curativa R0 en diez pacientes. Además, la terapia adyuvante se utilizó en 30 (33%) pacientes. La mediana de la supervivencia de nuestra serie fue de 12,5 meses, con supervivencias del 57%, 30% y 20% a uno, tres y cinco años, respectivamente. Conclusión: en conclusión, en todos los pacientes se debe plantear el tratamiento quirúrgico con resección tumoral completa, siempre y cuando la situación clínica del paciente lo permita

Introduction: gallbladder cancer is the most common biliary neoplasm and the sixth most common tumor of the digestive system. The disease has an ominous prognosis, with a 5-year survival rate of approximately 5%. It is usually diagnosed late and surgical resection is the only potential cure. Methods: a retrospective study was carried out in 92 patients with a pathological diagnosis of gallbladder cancer from January 2000 to January 2016. Results: the mean age of cases was 72 ± 11 years; 64 subjects were females and 28 were males. Symptoms at admission included abdominal pain (78%), anorexia (77%), nausea (76%) and jaundice (45%). Surgery was indicated in 92 (100%) patients and 59 (64%) underwent a curative/intent resection. The initial surgical procedures included simple cholecystectomy in 69 (75%) cases and extended cholecystectomy in eleven (11%) subjects. Rescue surgery was performed in 15 patients with tumor tissue in the cholecystectomy specimen; ten individuals underwent an R0 curative resection. Adjuvant therapy was administered in 30 (33%) patients. The median survival in our series was 12.5 months, with survival rates of 57%, 30% and 20% at one, three and five years, respectively. Conclusion: to conclude, surgical treatment with a complete tumor resection should be considered for all patients, provided that their clinical status allows it

Complete splenic embolization for the treatment of refractory ascites after liver transplantation.

Refractory ascites is an uncommon complication that may develop postoperatively after liver transplantation. The diagnosis and treatment of this condition is a real challenge. We report two cases of patients who underwent a transplant due to cryptogenic cirrhosis and developed refractory ascites during the immediate postoperative period. This is a serious complication associated with decreased survival by up to one year and a reduced quality of life. After ruling out the main causes of ascites, a portal hyperflow was a potential etiology. This condition perpetuates itself with splenic circulation and brings about a reduction in the hepatic arterial flow. Therefore, if arterial blood flow to the spleen is diminished, venous return and portal circulation will be reduced and arterial blood flow will improve. Splenic artery embolization is a procedure introduced many years ago for the management of splenic artery steal syndrome and small-for-size living donor liver transplantation. This procedure is performed in order to reduce portal hyperflow and consequently, ascites. In conclusion, splenic artery embolization is a therapeutic option for the treatment of refractory ascites after liver transplantation.

Liver-kidney simultaneous transplantation in adult patients with primary hyperoxaluria. Experience at Hospital Universitario 12 de Octubre.

Primary hyperoxaluria (PH) is a metabolic liver disease with an autosomal recessive inheritance that results in oxalate overproduction that cannot be metabolized by the liver. Urinary excretion of oxalate results in lithiasis and nephrocalcinosis leading to a progressive loss of renal function that often requires renal replacement therapy despite medical treatment. Type 1 PH is the most common form and is due to a deficiency in the alanine-glycolate aminotransferase enzyme found in hepatic peroxisomes. Therefore, a liver-kidney simultaneous transplant (LKST) is the definitive treatment for end-stage renal disease (ESRD) patients. However, some studies suggest that the morbidity and mortality rates are greater when this procedure is performed instead of only a kidney transplant (IKT). Herein, we report five patients with PH and a mean glomerular filtration rate of 20.2 ± 1.3 ml/min/1.73 m2 who received a LKST between 1999 and 2015 at the Hospital Universitario 12 de Octubre. Recurrence and liver or kidney graft loss was not observed during the postoperative period and only one case of late acute rejection without graft loss was diagnosed. The recipient survival rate was 100% with a median follow up of 84 months. As LKST is a curative and safe procedure with a low mortality and high survival rate, it must be considered as the treatment of choice in adults with HP and ESRD.

Mucinous appendiceal neoplasms: Incidence, diagnosis and surgical treatment. / Tumores mucinosos del apéndice: incidencia, diagnóstico y tratamiento quirúrgico.

INTRODUCTION: Mucinous tumors of the appendix are a rare pathology, with a prevalence below 0.5%. Clinical presentation usually occurs during the sixth decade of life, and mucinous tumors can clinically mimic acute appendicitis. The aim of this study is to describe the clinical and demographic variables, therapeutic procedure and diagnosis of these tumors. We analyze the association between mucinous tumors and pseudomyxoma peritonei (PP), as well as the association with colorectal and ovarian tumors. METHODS: A retrospective study was performed including patients who underwent an appendectomy between December 2003 and December 2014. RESULTS: Seventy-two mucinous tumors of the appendix were identified among 7.717 patients reviewed, resulting in a prevalence of 0.9%. Mean age at presentation was 64 years, 62% patients were female and 38% males. An incidental diagnosis was made in 43% of patients. Mucinous tumors of low malignant potential were significantly related to the presence of pseudomyxoma peritonei, identified in 16 (22%) of the cases. We also observed an increased risk of ovarian mucinous tumors in patients with a diagnosis of appendiceal mucinous neoplasm. In our sample, 22 (30.5%) patients showed a synchronous or metachronous colorectal cancer. CONCLUSIONS: Appendiceal mucinous tumors are frequently an incidental finding. The diagnosis of mucinous tumors of low malignant potential is a factor associated with the development of pseudomyxoma peritonei. Histologic tumor grade and the presence of peritoneal dissemination will determine surgical treatment that can vary, from appendectomy to cytoreductive surgery.
