RESUMO

BACKGROUND: Percutaneous ethanol injection has been successfully used for hepatocellular carcinomas (HCC) smaller than 5 cm in size. For larger lesions large volume ethanol injection has not been well explored. AIM: Evaluate the results of intraoperative Ultrasonographic-guided large volume ethanol injection for HCC larger than 4 cm in size. PATIENTS AND METHODS: Ten patients were candidates for this treatment between June 1999 and July 2003. A retrospective review of the clinical files was performed. Absolute ethanol, average of 100 mL (range 80-120 mL) was administered intraoperatively. Follow-up evaluation included alpha-fetoprotein (AFP) and ultrasound or computed tomography. RESULTS: There were six women and four men, the median age was 62 years (range 56-80). The median lesion size was 8 cm (range 4-15 cm). Hepatitis C liver cirrhosis was the most common associated chronic liver disease (70%). A significant reduction of AFP levels after treatment was observed (Initial 966 ng/dL, post treatment levels: 42 ng/dL) US and CT scan showed tumor necrosis. Morbidity was 40%. No operative mortality was recorded. The one and four year survival rate was 60% and 20%. CONCLUSION: Intraoperative US-guided large volume ethanol injection is a safe palliative therapy for cirrhotic patients with HCC lesions greater than 5 cm in size. The impact on survival should be compared in a controlled double blind study.

RESUMO

BACKGROUND/AIMS: Hepatocellular carcinoma (HCC) is a very rare disease among young individuals. Epidemiological, clinical and histopathological features of this malignancy in the youth have not been thoroughly studied. METHODOLOGY: A review of the clinical files of patients with HCC younger than 40 years of age, who were treated between May 1990 and July 2002, was performed. RESULTS: Seventeen patients were included for analysis; nine were female and eight male. The mean age at diagnosis was 24 years (range 12-39 years). Abdominal pain was the main symptom, followed by vomiting and nausea. Enlargement of the liver was observed in 11 patients (65%). In seven patients (41%), an etiological factor was not found. Five of these cases were of the fibrolamellar variant (29%). Only four patients were resected (23%) two of which belonged to the fibrolamellar type. Three patients (18%) are still alive after 64.9 months of follow-up. CONCLUSIONS: HCC is a very uncommon disease in the youth and affects similarly both genders. It is discovered at an advanced stage. Hepatitis B and C are uncommon etiological factors. The frequency of fibrolamellar carcinoma is higher in this age group. Though resection is more feasible, the overall survival rates remain low.

RESUMO

INTRODUCTION: Laparoscopic surgery has been widely used for digestive tract diseases, specially for gallbladder pathology. Laparoscopic liver surgery pretends to accomplish the same objectives of open surgery but with the advantages of minimally invasive surgery. AIMS: To evaluate the indications and recent results of laparoscopic liver surgery, as well as the technique. MATERIAL AND METHODS: A review of the world literature was performed on the roll of laparoscopic surgery for hepatic diseases. The results of the authors are also reported. RESULTS: Nowadays hepatic laparoscopic surgery is reserved for anterior non-parasitic liver cysts and type I polycystic liver disease. The treatment of choice is wide deroofing. For hydatic liver disease pericystectomy or wide deroofing plus omentoplasty are also described. For benign solid liver disease, hepatic resection can be performed with the same outcome that the one observed with open surgery when the lesions are symptomatic, small, anterior or peripherally located. Laparoscopic liver surgery is recommended for the treatment of malignant hepatic lesions only in very specific cases. Nonetheless there are no prospective randomized studies that show benefits of laparoscopic over open surgery. Several local ablative therapies like radiofrequency, ethanol injection, cryotherapy or laser can be also performed through the laparoscope. The results reported so far have been encouraging. Intra-arterial chemotherapy is an option for the treatment of liver malignancies via laparoscopy, considering that the arterial catheter can be placed under this approach. CONCLUSIONS: For years, the liver has been considered a challenging organ for its approach, even with open surgery. Laparoscopic liver surgery should be performed by an experienced surgeon with the adequate technology. To our knowledge there are no reported results that decisively point toward the benefits of laparoscopic surgery over open surgery for the management of liver disease. Nonetheless more experience in laparoscopic liver surgery is needed.

RESUMO

BACKGROUND/AIMS: To compare patients with gallbladder cancer treated with radical resection and regional lymphadenectomy (RR-RL) versus simple cholecystectomy and adjuvant external radiotherapy (SC-ERT) and determine outcome. METHODOLOGY: Presentation, operative data, complications and survival were examined in 137 patients. In particular, the 45 patients treated with RR-RL or SC-ERT. RESULTS: Twenty-five had SC-ERT and 20 had a RR-RL. There were no epidemiological differences between groups. Resection of segments IV-b and V and en bloc dissection of regional lymph nodes was the most frequently used procedure (75%). The morbidity and mortality of the radical procedure were 25% and 10%. The morbidity of SC-ERT was 16%. All patients with Nevin I are alive. For lesions Nevin II and Nevin III RR-RL offered a 100% 5-year survival rate and SC-ERT had a 62% and 39% 5-year survival rate respectively. For lesions Nevin IV and V there was no difference in long-term survival. CONCLUSIONS: RR-RL is better than SC-ERT in patients with Nevin II and III lesions because it improves survival rate. SC-ERT can be recommended as an alternative treatment. For more advanced lesions further trials are needed.

RESUMO

Neuroendocrine or carcinoid tumors of the gastrointestinal tract considered previously extremely rare, are diagnosed at present with increased frequency due to the better capacity to identify neuroendocrine system cells in normal and pathologic conditions. Occasionally, these tumors secrete a great variety of vasoactive substances, producing the carcinoid syndrome. Gastric carcinoids are classified, according to their degree of differentiation into well differentiated and poorly differentiated tumors, also called neuroendocrine carcinomas. Neuroendocrine gastric carcinomas or poorly differentiated gastric carcinoids are seen in 5-15% of all gastric carcinoids, mainly in older male patients. Generally they are large, very aggressive tumors with extensive local infiltration. Due to poor differentiation, they are not frequently associated with an endocrine syndrome. They can be located in any part of the stomach but are mainly seen in antrum. These tumors have an aggressive behavior and must be treated in a radical manner; recurrences are not uncommon. We report the case of a patient with a neuroendocrine gastric carcinoma treated with an en bloc subtotal gastrectomy and colectomy.

RESUMO

INTRODUCTION: Cavernous hemangioma is the most frequent focal liver lesion. It affects mainly women and may cause symptoms such as abdominal pain, mass, and early satiety, or complications such as heart failure or coagulopathy. There are several options for treatment in symptomatic patients. However, it seems that surgical resection is the only curative treatment. AIM: Evaluate indications and results of liver resection in patients with cavernous hemangiomas and hepatic hemangiomatosis. PATIENTS AND METHODS: We conducted a retrospective analysis of clinical files of patients treated at the Instituto Nacional de Cancerología (INCan) and the Centro Médico ISSEMYM during a 8-year period. Epidemiological data as well as diagnostic work-up and treatment were analyzed. RESULTS: From August 1995 to May 2003, 24 patients with liver hemangiomas were resected at both institutions. Twenty three were female (95.8%) and one, male (4.1%). Indications for surgery were presence of symptoms in 20 patients (83.3%), undefined diagnosis in three (12.5%), and rapid growth in one (4.1%). Most frequent symptoms were abdominal pain in 20 (83.3%) patients, followed by abdominal mass in five (20.8%), and early gastric satiety in four (16.6%). Abdominal computed tomography (CT) scan was the most frequent imaging study used in 22 patients (91.6%), followed by ultrasound in 20 (83.3%). Size of lesion ranged from 4-30 cm (X: 8.7 cm), 16 patients were submitted to formal liver resection (66.6%), and eight to enucleation (33.3%). Four patients presented operative complications (16.6%) that included postoperative bleeding in two (8.3%), fever in one (4.1%) and abdominal haematoma in one (4.1%). There was no operative mortality. Twenty two patients were asymptomatic at time of evaluation (91%). CONCLUSIONS: This lesion affects mainly women, and presence of symptoms is the most common indication for treatment. Choice of surgical procedure to be carried out depends on location and morphology of the lesion. Liver resection or enucleation are safe forms of treatment that properly controlled symptomatology.

RESUMO

The authors report the case of a 34-year-old woman who presented liver metastases from a virilizing lipoid cell ovarian tumor. The patient complained of right upper quadrant abdominal pain, strong virilization and secondary amenorrhea. She developed hirsutism and irregular menses at the age of 23, and a salpingo-ooforectomy for a right ovarian lipoid cell tumor was performed. She was asymptomatic but 6 months before admission she presented abdominal pain. The computed tomography scan showed a large right-side hypodense liver lesion. Tumor and viral markers were normal. Serum testosterone was 7 ng/mL and the dehydroepiandrosterone was 2.5 ng/mL. A right trisegmentectomy was performed. Her recovery was uneventful, hormone levels returned to normal, and she has been asymptomatic after a follow-up of 6 months.

RESUMO

OBJECTIVE: Cholangiocarcinoma is a rare malignant tumor that may occur anywhere along intra or extrahepatic biliary tree. Prognosis remains poor with overall 5-year survival rate of 5%. Experience in management of this lesion in Mexico is scarce. Our objective was to report on our experience at the Instituto Nacional de Cancerología in Mexico City with the management of this lesion. PATIENTS AND METHODS: A retrospective review of clinical files of patients diagnosed and treated in a period of 10 years was performed. Epidemiologic data, forms of diagnosis, results of management, and survival were analyzed. RESULTS: From June 1992 to June 2002, 36 patients were diagnosed and treated; 25 patients had perihilar tumor (Klatskin tumor) and 11 had peripheral cholangiocarcinoma. Twenty seven were females (75%) and nine males (25%). Abdominal pain was the main symptom (72%) followed by jaundice (65%) and weight lost (59%). Computed tomography was the most used imaging study (86%); surgery was main form of management (72%). No survivors were observed in patients nor receiving treatment after a follow-up of 3 years. For those resected, an 18%, 5-year survival was observed. CONCLUSIONS: This lesion was more frequent in females between fifth and seventh decades of life and no relation with ulcerative colitis or primary sclerosing cholangitis was observed in our study. Surgery is still the best form of management but prognosis remains poor.

RESUMO

Objetivo: evaluar las indicaciones y los resultados de la cirugía en los tumores hepáticos benignos (THB). La resección continúa siendo la mejor forma de manejo para los THB sintomáticas, en los últimos años los resultados operatorios han mejorado en centros de gran experiencia.Pacientes y método: se revisaron los expedientes clínicos de pacientes con THB operados durante el periodo de mayo de 1995 a diciembre de 1999.Resultados: se operaron 17 pacientes, 15 fueron mujeres y dos hombres. La edad promedio fue de 45 años (margen 32-68 años). Fueron 11 hemangiomas cavernosos, dos adenomas hepáticos, dos hiperplasias nodulares focales, un angiomiolipoma hepático y un adenofibroma biliar. Presentaban síntomas doce pacientes (70 por ciento), tres fueron operados con imágenes sospechosas de malignidad, uno por crecimiento acelerado y otro por su estirpe histológica. El tamaño promedio de la lesión fue de 7 cm (margen 3-19 cm). Se realizaron siete resecciones mayores que incluyeron cinco hepatectomías derechas y una izquierda, así como una trisegmentectomía izquierda. Diez resecciones menores (cinco resecciones del segmento lateral izquierdo, tres enucleaciones, dos segmentectomías). La hemorragia intraoperatoria promedio fue de 1,200 mL (margen de 100 a 3,000 mL). Dos pacientes (11.7 por ciento) presentaron complicaciones y no se presentó mortalidad operatoria. El seguimiento promedio fue de 26 meses (margen de 2 a 52 meses) y todos se encuentran asintomáticos al momento de la publicación. Se concluye que la selección cuidadosa de los casos permite realizar la resección de estas lesiones, con adecuados márgenes de seguridad, que permiten eliminar la sintomatología.

RESUMO

Se presenta el caso clínico de una mujer de 47 años de edad que fue referida con dolor abdominal y una lesión focal en el segmento lateral izquierdo del hígado. Después de realizar estudios de extensión tumoral se practicó segmentectomía lateral izquierda por abordaje laparoscópico. Su evolución no presentó complicaciones y fue egresada en el segundo día postoperatorio. El reporte histopatológico fue de hiperplasia nodular focal. Hasta donde conocemos, éste es el primer caso operado con este abordaje en México.

RESUMO

Objetivo: evaluar las indicaciones y los resultados obtenidos en 75 resecciones hepáticas. Introducción: en los últimos años la morbilidad y la mortalidad de este procedimiento en centros especializados, ha disminuido en parte por menor hemorragia intraoperatoria y por mejor manejo perioperatorio. Material y método: se revisaron los expedientes clínicos de 72 pacientes quienes fueron sometidos a 75 resecciones hepáticas en un periodo de 4 años. Resultados: 52 realizadas a mujeres y 23 a hombres. El margen de edad varió de 15 a 88 años (x :50 + 22 años). Las indicaciones de cirugía fueron metástasis hepáticas en 28, carcinoma de vesícula y/o vía biliar en 17, tumores hepáticos benignos en 16, y tumores primarios malignos en 14. Se realizaron 47 resecciones mayores que incluyeron 25 hepatectomías derechas, 13 hepatectomías izquierdas, 5 trisegmentectomías derechas y 4 trisegmentectomías izquierdas. Veintiocho resecciones menores que incluyeron 12 resecciones del segmento lateral izquierdo, 9 bisegmentectomías, 5 segmentectomías y 2 resecciones del lóbulo caudado. El tiempo de cirugía varió de 60-540 min (x :260 + 97min), el promedio de hemorragia intraoperatoria fue de 1439 + 660 mL (margen 20-5000 mL). En 63 pacientes se utilizó la maniobra de Pringle y el tiempo promedio de isquemia fue de 42 + 25 minutos (margen 20-100 minutos). Presentaron complicaciones 25 pacientes (33 por ciento), 3 intraoperatorias y 22 posoperatorias, siendo las más frecuentes: la insuficiencia hepática, la hemorragia intraabdominal, la ascitis y las colecciones biliares. La mortalidad operatoria (< 30 días) fue de 8 por ciento. Cuatro pacientes fallecieron por insuficiencia hepática y falla orgánica múltiple, uno por neumonía e infarto del miocardio y uno por sepsis. Conclusiones: la resección hepática es una excelente alternativa terapéutica en pacientes con lesiones hepáticas focales benignas y malignas.

RESUMO

El angiomiolipoma es un tumor benigno del hígado poco frecuente. Se presenta el caso de una paciente de 32 años de edad, a quien se le realizó ultrasonido abdominal por sospecha de embarazo, detectándose masa hiperecoica en el lóbulo izquierdo del hígado, misma que se corroboró por tomografía. La biopsia percutánea reportó neoplasia maligna compatible con liposarcoma, por lo que se decidió realizar laparotomía exploradora, efectuando resección hepática, que evolucionó sin complicaciones. El informe anatomopatológico fue de angiomiolipoma de hígado. Este caso demuestra la dificultad para realizar el diangóstico preoperatorio de lesiones grasas en hígado, por lo que se revisó la literatura y se discutió el diagnóstico, así como el tratamiento de estas lesiones

RESUMO

Objetivo. Determinar si existen diferencias en la aparición de alteraciones hepáticas secundarias al uso de doble contra triple esquema inmunosupresor en pacientes trasplantados de riñon. Diseño. Encuesta retrospectiva, observacional, transversal y descriptiva. Análisis estadístico: Chi cuadrada. Sede. Hospital de tercer nivel de atención médica. Pacientes y métodos. Se incluyeron 80 pacientes, los cuales se dividieron en dos grupos. Grupo I. a los que se les administró azatioprina y prednisona. Grupo II. a quienes se les dio triple esquema con azatioprina-prednisona-ciclosporina. Cada grupo se intregró con 40 pacientes. A cada enfermo se le hizo examen clínico, determinación de pruebas de función hepática y renal; estudios de gabinetes que incluyó: Ultrasonido y gammagrama. Se hizo biopsia hepática a los pacientes que presentaron manifestaciones clínicas de hepatopatía. Resultados. Veintiocho pacientes presentaron datos de disfunción hepática, en 6 secundaria a hepatitis tipo B, en 3 por hepatitis tipo C, 1 por hapatitis por citomegalovirus y en 18 secundaria al empleo de medicamentos inmunosupresores. De éstos, 13 se encontraron asintomáticos, presentaron exlcusivamente alteraciones bioquímicas, 5 tuvieron sintomatología. Las mujeres fueron afectadas con mayor frecuencia en ambos grupos, el grupo II resultó más afectado, (p<0.05); la frecuencia de hepato toxicidad fue mayor y se presentó en forma temprana, sin embargo, la severidad de la lesión fue similar en ambos grupos. Conclusión. La disfunción hepática por medicamentos es un problema frecuente en el paciente que es sometido a un trasplante, los enfermos que reciben triple esquema de inmunosupresión son más susceptibles a desarrollar efectos adversos en función hepática

RESUMO

El absceso hepático piógeno, frecuentemente es secundario a infecciones intrabdominales. Sin embargo, en el paciente diabético, esta asociación no es un requisito. Los gérmenes formadores de gas afectan al diabético produciendo diversas entidades nosológicas como colecistitis enfisematos, apendicitis gangrenosa, abscesos perinefríticos, fascitis necrosante entre otros. Presentamos el caso de un paciente diabético de 47 años de edad al que se le diagnosticó un absceso hepático por gérmenes formadores de gas que se trató mediante punción percutánea y antibióticos. Se analizan los factores predisponentes a la aparición de esta asociación, así como la forma de manejo en la actualidad

RESUMO

Se informa el caso de un adenoma de la gándula suprarrenal productor de aldosterona. Pacientes femenina de 54 años de edad que acude a consulta médica por presentar hipertensión arterial, debilidad extrema, y parestesias. Sus estudios de laboratorio demostraron hipokalemia severa, hipernatremia, hiperaldosteronemia e hiporreninemia. La tomografía de abdomen demostró un nódulo en la glándula suprarrenal derecha el cual fue resecado con abordaje posterior. El reporte histopatológico fue de un adenoma suprarrenal producto de aldosterona compatible con síndrome de Conn. El hiperaldosteronismo primario es una enfermedad rara, causante de hipertensión aterial en el 0.5 por ciento de los pacientes hipertensos, habitualmente es secundario a un adenoma de la glándula suprarrenal. El manejo quirúrgico revierte los trastornos metabólicos en la mayoría de los casos

RESUMO

El hepatoblastoma es el tumor hepático primario maligno más frecuente en el niño; en el adulto, es extremadamente raro y sólo 27 casos han sido descritos en la literatura. El pronóstico de esta neoplasia es malo debido a que habitualmente se descubre en forma tardía. La cirugía, la quimioterapia y el trasplante hepático han sido utilizados como tratamiento con malos resultados. Presentamos dos pacientes adultos a quienes se les diagnósticó hepatoblastoma epitelial. Se hace una revisión de su patogénesis, características clínicas, histológicas y manejo actual
