RESUMEN
Introducción: El cáncer de páncreas (CP) tiene un pronóstico ominoso a pesar de los avances en técnica quirúrgica y en los cuidados peri/postoperatorios. Nuestro objetivo fue identificar factores asociados a mayor sobrevida en pacientes con CP tratados mediante pancreatoduodenectomía (PD). Material y Método: Estudio de casos y controles de pacientes con CP tratados mediante PD en el Hospital Clínico de la Universidad Católica entre 2002-2015. Se definió como caso al paciente con sobrevida ≥ 3 años y como control a aquel con sobrevida inferior a ese plazo. Se comparó entre casos y controles datos biodemográficos, clínicos, histopatológicos, de morbilidad y mortalidad mediante regresión logística. Resultados: Se analizaron 70 pacientes, con una edad media de 62 ± 11 años; 40 (57%) mujeres. Hubo morbilidad en 26 enfermos (37,1%); Clavien-Dindo ≥ Illa en 8 (11,4%). La mediana (rango) de días de hospitalización fue 12 (7-84). La sobrevida actuarial a 1, 3 y 5 años fue 77%, 32% y 22% respectivamente. Se identificaron 21 casos (30%) y 49 controles (70%). En el análisis univariable, la resección R0, los ganglios regionales negativos, la ausencia de infiltración perineural, los estadios más precoces (IA, IB y IIA) y la ausencia de diabetes mellitus (DM2) al momento del diagnóstico, fueron variables asociadas a sobrevida ≥ 3 años (p 100 U/mL) y los tratamientos complementarios no se asociaron a diferencias significativas en sobrevida. En el análisis multivariable, se identificó la ausencia de DM2 (OR ajustado: 12; IC95% 1,7-84,3), la ausencia de infiltración perineural (OR ajustado: 7; IC95% 1,3-36,3) y los estadios precoces IA, IB y IIA (OR ajustado: 10,3; IC95% 2,1-49,1) como los factores independientes asociados a sobrevida mayor a 3 años. Conclusión: Los pacientes no diabéticos, con etapas precoces del CP sin infiltración perineural, resecados R0 mediante PD pueden obtener una sobrevida mayor a 3 años.
Introduction: Pancreatic cancer (PC) remains one of the most lethal malignancies, despite developments in surgical and non-surgical therapies. Significant improvements in long-term survival have not been achieved. Only radical surgical resection has obtained a moderate extension in survival. We aim to identify factors associated with longer survival in patients with PC treated by pancreatoduodenectomy (PD). Material and Method: We designed a case-control study of patients with PC treated by PD in our center between 2002-2015. We compare patients who survived ≥ 3 years (case) with those not achieving it (control). Bio-demographic, clinical, histopathological, morbidity and mortality data were compared between cases and controls using logistic regression. Results: Seventy patients were analyzed; mean age 62 ± 11 years; 40 (57%) women. Morbidity was found in 26 patients (37.1%); Clavien-Dindo ≥ Illa in 8 (11.4%). The median (range) of hospitalization days was 12 (7-84). The actuarial 1, 3, and 5 years survival was 77%, 32%, and 22%, respectively, for the entire series. Twenty-one cases (30%), and 49 controls (70%) were identified. In the univariate analysis, R0 resection, negative regional lymph nodes, the absence of perineural infiltration, the earliest stages (IA, IB, and IIA) and the absence of diabetes mellitus (DM) at time of diagnosis were variables associated with survival ≥ 3 years (p 100 U / mL), and neo/adjuvant treatments, did not significantly show differences in survival. In the multivariate analysis, no DM at diagnosis (adjusted OR: 12; 95% CI 1.7 - 84.3), no perineural infiltration (adjusted OR: 7; 95% CI 1.3 - 36.3) and early stages IA, IB, and IIA (adjusted OR: 10.3; 95% CI 2.1 - 49.1) were identified as independent factors associated with survival > 3 years. Conclusion: Nondiabetic patients with early stages PC without perineural infiltration, resected R0 by PD can achieve survival over 3 years.
RESUMEN
Resumen Introducción: La cirugía hepática laparoscópica ha presentado un desarrollo más lento debido a la complejidad que ésta posee, lo que determina una curva de aprendizaje prolongada. En relación a la hepatectomía laparoscópica para donante vivo en trasplante hepático (TH), ésta se ha retrasado aún más por las preocupaciones sobre la seguridad del donante, el resultado del injerto y la adquisición de las competencias técnicas de los cirujanos. El objetivo de este artículo, es exponer detalles técnicos de la hepatectomía izquierda laparoscópica de donantes vivos adultos para trasplante pediátrico y se presentan los resultados quirúrgicos de los casos realizados en este centro. Materiales y Método: Presentación de la técnica quirúrgica de la hepatectomía izquierda en donantes vivos para TH en receptores pediátricos, además, de realizar un estudio cohorte no concurrente de pacientes sometidos a esta cirugía en el Hospital Clínico de la Universidad Católica entre mayo de 2011 y noviembre de 2017. Resultados: La serie consta de 15 pacientes, 60% sexo femenino. Trece pacientes (86,6%) eran madre o padre del receptor. El 100% de pacientes fue sometido a hepatectomía izquierda laparoscópica sin necesidad de conversión. Morbilidad Clavien-Dindo >3,1 paciente requirió punción percutánea de bilioma. Mediana de hospitalización de 3 días (2-5). No hubo mortalidad. Conclusión: La hepatectomía izquierda por vía laparoscópica de donante vivo para TH pediátrico es un procedimiento seguro y factible de realizar en este centro, con excelentes resultados en términos de morbimortalidad y consideramos que esta técnica debe ser la vía de elección para donantes vivos adultos-pediátricos.
Introduction: Laparoscopic liver surgery has presented a slower development due to the complexity it has, which determines a prolonged learning curve. In relation to laparoscopic hepatectomy for a living donor liver transplantation (LT), this has been further delayed due to concerns about donor safety, graft results and the acquisition of the technical skills of surgeons. The objective of this article is to present technical details of the laparoscopic left hepatectomy of adult living donors for pediatric transplantation and the surgical results of the cases performed in this center. Materials and Method: Presentation of the surgical technique of left hepatectomy in living donors for LT in pediatric recipients in addition to conducting a non-concurrent cohort study of patients undergoing this surgery at the Hospital Clinico Universidad Catolica between May 2011 to November 2017. Results: The series consists of 15 patients, 60% female. Thirteen patients (86.6%) were mother or father of the recipient. 100% of patients underwent laparoscopic left hepatectomy without conversion. Clavien-Dindo Morbidity > 3, in 1 patient who required percutaneous drainage of biloma. Median hospitalization of 3 days (2-5). There was no mortality. Conclusión: Laparoscopic left hepatectomy of living donors for pediatric LT is a safe and feasible procedure to perform in this center, with excellent results in terms of morbidity and mortality and we consider that this technique should be the route of choice for adult-pediatric living donors.

Resumen Introducción: El trasplante hepático (TH), es una terapia establecida en el tratamiento de diversas enfermedades del hígado agudas y crónicas terminales y del carcinoma hepatocelular (CHC). Las principales indicaciones en nuestro medio son la cirrosis de diferentes etiologías, el CHC, la atresia de vías biliares en niños y la falla hepática fulminante (FHF). Menos del 10% corresponden a indicaciones inhabituales, que incluyen pacientes con una miscelánea de enfermedades entre las cuales están la enfermedad poliquística hepática (EPH), enfermedades metabólicas (Niemann-Pick, otras), el síndrome hepato/portopulmonar, metástasis de diferentes tumores, etc. Objetivo: Describir y evaluar los resultados obtenidos con el trasplante hepático en estas indicaciones. Materiales y Método: Estudio de cohorte no concurrente que incluyó los TH por indicaciones inhabituales realizados entre marzo de 1997 y diciembre de 2016. De 295 TH realizados, 34 (11,5%) fueron por estas indicaciones. Resultados: Las causas más frecuentes fueron el síndrome porto/hepatopulmonar en 11 (40,7%) pacientes y la EPH en 9 (26,5%). Las enfermedades metabólicas representaron la tercera indicación, con 5 (14,7%) casos. Siete (20,6%) pacientes eran menores de 18 años. Las complicaciones más frecuentes fueron biliares y la trombosis de arteria hepática en 6 (17,6%) y 4 (11,8%) casos respectivamente; estos últimos eran portadores de una EPH masiva. Cuatro (12,5%) pacientes requirieron retrasplante. La mortalidad a 90 días fue de 2 (5,9%) enfermos. Conclusión: El TH es una opción factible en este grupo de pacientes con resultados similares a los obtenidos en las indicaciones clásicas.
Introduction: Liver transplantation (LT) is an established therapy in the treatment of several acute and chronic end-stage liver diseases and hepatocellular carcinoma (HCC). The main indications worldwide are cirrhosis of different etiologies, HCC, biliary atresia in children, and fulminant hepatic failure (FHF). Less than 10% concerns unusual indications which include patients with miscellaneous diseases among which are hepatic polycystic disease (HPD), metabolic diseases (Niemann-Pick, others), portal/hepatopulmonary syndrome, metastasis of different tumors, among others. Aim: The objective of the study is to describe and asses the results obtained with liver transplantation in these indications. Materials and Method: We performed a non-concurrent cohort study that included all LT due to unusual indications between March 1997 and December 2016 in a university medical center. Of 295 TH performed, 34 (11.75%) were due to these indications. Results: The most frequent causes were the portal/hepatopulmonary syndrome in 11 (40.7%) patients and HPD in 9 (26.5%). Metabolic diseases accounted for the third indication in 5 (14.7%) cases. Seven (20.6%) patients were less than 18 years old. The most frequent complications were biliary and hepatic artery thrombosis (HAT) in 6 (17.6%) and 4 (11.8%) cases, respectively. Patients complicated by a HAT suffered a massive EPH. Four (12.5%), required retransplantation. Mortality at 90 days was 2 (5.9%). Conclusión: LT is a feasible option in this group of patients with results similar to those obtained in classic indications of LT.

Resumen El cáncer colorrectal es de las principales causas de muerte por cáncer a nivel mundial. Una proporción importante de los casos desarrolla metástasis hepáticas. Gracias a los avances diagnósticos y tratamientos oncológicos, la sobrevida ha ido en aumento, sin embargo, para ello es fundamental lograr la resección quirúrgica completa de las lesiones primarias y metastásicas con márgenes microscópicos negativos (R0). Existen numerosos procedimientos y técnicas diseñadas para este objetivo como la quimioterapia neoadyuvante, embolización portal, cirugía en etapas, etc. A pesar de ello, hay casos no resecables por compromiso hepático bilobar, multisegmentario y/o compromiso de vasos arteriales, portales o venosos que en caso de resección, no permiten mantener hígado remanente funcional compatible con la vida del paciente. El trasplante hepático surge como alternativa radical para el tratamiento de casos no resecables. Dado la escasez de donantes y mortalidad en la lista de espera nacional, no es aceptable ocupar hígados del pool de donantes para patologías con criterios expandidos como metástasis colorrectales. Sin embargo, con el recurso del donante vivo de adulto a adulto, hoy en día es posible indicar trasplante en casos seleccionados, que cumplan con todos los criterios establecidos.
Colorectal cancer is one of the leading causes of cancer death worldwide. A significant proportion of cases develop liver metastases. Thanks to diagnostic advances and oncologic treatments, survival has been increasing, however, it is essential to achieve complete surgical resection of primary and metastatic lesions with negative microscopic margins (R0). There are many procedures and techniques designed for this purpose such as neoadjuvant chemotherapy, portal embolization, stage surgery, etc. Despite this, there are non-resectable cases due to bilobar, multisegmental and/or hepatic involvement of arterial, portal or venous vessels that, in case of resection, do not allow the maintenance of functional remnant liver compatible with the patient's life. Liver transplantation emerges as a radical alternative for the treatment of unresectable cases. Given the shortage of donors and mortality on the national waiting list, it is not acceptable to occupy donor pool livers for pathologies with expanded criteria such as colorectal metastases. However, with the resource of the living donor from adult to adult, today it is possible to indicate transplantation in selected cases, which meet all established criteria.

Se presenta el caso de un paciente, hombre de 74 años, portador de hipertensión arterial crónica y diabetes mellitus Tipo 2, portador de un cáncer de colon derecho recientemente diagnosticado y que tenía planificada cirugía electiva. Es ingresado de urgencia al Hospital del Salvador por un cuadro de calofríos y fiebre alta de tres días de evolución, cuyo estudio descartó foco séptico pulmonar, urinario y otros, incluyendo Ecocardiograma para descartar una endocarditis. Solo se demostraron dos hemocultivos positivos para Streptococcus anginosus, siendo tratado exitosamente con Ceftriaxona y Metronidazol. Es intervenido quirúrgicamente al 7º día, encontrándose un tumor abscedado de colon derecho. Evolución postoperatoria satisfactoria, siendo dado de alta al 5º día del postoperatorio.
We report a 74 years old hypertensive and diabetic male with a recently diagnosed right colon cancer that consulted in the emergency room for fever and chills lasting three days. He was admitted, two blood cultures were positive for Streptococcus anginosus, treatment with Ceftriaxone and Metronidazole was started and fever subsided after four days of treatment. The surgical exploration showed that the colon cancer was abscessed and was the origin of the sepsis. The patient was discharged in good conditions five days later.

Background: Wheat flour in Chile is fortified with folie acid and pregnant women are also supplemented with the vitamin, but the population level of knowledge or awareness about this vitamin and its use by pregnant women is unknown. Aim: To assess the level of knowledge that postpartum women from Santiago de Chile have about folie acid. Material and methods: A questionnaire about folie acid and its efects on the prevention of neural tube defects was developed adapting questionnaires designed abroad. It was applied by medical students to puerperal women, hospitalized in public hospitals. Results: The questionnaire was applied to 342 women aged 26 ± 7 years. Sixty one percent were housewives and 55 percent completed high school education. Forty seven percent of these women had heard about folie acid, 9.6 percent knew that it was able to prevent congenital defects and only one received an adequate supplementation during pregnancy. Women aged 25 to 34 years and those with an adequate medical care during pregnancy had a significantly better knowledge about folie acid and its role in the prevention of congenital anormalies. The more commom means to receive information about folie acid were midwifes (34 percent), mass media (28 percent) and doctors (20 percent). Two hundred eleven women (62 percent) agreed to take folie acid in a future gestation and 58 percent preferred to do so using fortified foods. Conclusions: Post partum women from Santiago have a poor knowledge about the relevance of folie acid supplementation.

Introduction: intake of Folic Acid (FA) before conception and during early pregnancy reduces the incidence of neural tube defects (NTD). In Chile the management of the pregnant adolescent women is a relevant public health problem. So, the aim of this study was to determine the level of knowledge and intake of FA in a sample of adolescent and older parturient. Methods: a survey was conducted in one group of teenagers (group A) and another group of older puerperal (group B) corresponding to four public maternities of Santiago. Results: finally, 79 teenagers and 263 older women were surveyed. Both groups showed a poor knowledge about the benefit of intake of FA during this period. Regarding the control before pregnancy, we found an attendance of 10.1 percent in the group A and 24.7 percent in the group B, whereas only 5.1 percent of the group A and 1.9 percent of the group B had an intake of FA according to the medical recommendation. Conclusion: our patients have scanty information about the benefits of the periconceptional intake of FA. It seems necessary to design new methods and tools in order to increase the use of the FA in women of childbearing age, especially in the groups at risk for NTD.
