ABSTRACT

Introducción. La disección espontánea del tronco o arteria celíaca es una emergencia vascular abdominal inusual, con una incidencia desconocida. Actualmente no existen guías o consensos para su tratamiento, el cual va desde intervenciones vasculares mayores hasta la conducta expectante. Caso clínico. Paciente masculino de 42 años sin antecedentes patológicos, con dolor abdominal intenso de un mes de evolución. Ante la sospecha clínica de patología inflamatoria se realizó una tomografía computarizada abdominal con medio de contraste, en la que se observó una disección del tronco celíaco asociada a un infarto esplénico. Se realizó manejo endovascular de forma exitosa. Discusión. La disección espontánea del tronco celíaco es una patología infrecuente, que puede presentarse en pacientes con hipertensión arterial, tabaquismo, enfermedad ateroesclerótica y vasculitis. Los síntomas más comunes son el dolor abdominal asociado a náuseas y vómito. La sospecha clínica debe ser confirmada mediante estudios imagenológicos que orienten al tratamiento conservador, endovascular o quirúrgico, ante la sospecha de infarto intestinal o ruptura arterial. Conclusiones. La disección espontánea del tronco celíaco es una patología vascular inusual que puede relacionarse con una alta mortalidad. Es importante tener siempre presente la interrelación entre la anatomía vascular abdominal, la anamnesis y el examen físico como elementos claves para realizar este diagnóstico.


Introduction. Spontaneous dissection of the celiac artery or trunk is an unusual abdominal vascular emergency, with an unknown incidence. Currently there are no guidelines or consensus for its treatment, which ranges from major vascular interventions to expectant management. Clinical case. A 42-year-old male patient with no medical history, with intense abdominal pain of one month of evolution. Given the clinical suspicion of inflammatory pathology, an abdominal computed tomography with contrast was performed, in which a dissection of the celiac trunk associated with a splenic infarction was observed. Endovascular management was performed successfully. Discussion. Spontaneous dissection of the celiac trunk is an infrequent pathology, which can occur in patients with high blood pressure, smoking, atherosclerotic disease, and vasculitis. The most common symptoms are abdominal pain associated with nausea and vomiting. Clinical suspicion must be confirmed by imaging studies that guide conservative, endovascular or surgical treatment in the event of suspected intestinal infarction or arterial rupture. Conclusions. Spontaneous dissection of the celiac trunk is an unusual vascular pathology that can be associated with high mortality. It is important to always keep in mind the relationship between the abdominal vascular anatomy, anamnesis, and physical examination as key elements in making this diagnosis.

ABSTRACT

Se describe el caso clínico de un paciente de 58 años de edad con antecedentes personales de insuficiencia cardiaca congestiva mal controlada, quien acudió a emergencias del Hospital Luis Bernaza de Guayaquil, Ecuador, por presentar dolor abdominal difuso, constipación y masa inguinoescrotal gigante. Se realizan los estudios pertinentes y se diagnostica una hernia inguinoescrotal gigante con pérdida de domicilio, sin datos de obstrucción intestinal. Se empleó la técnica de Goñi Moreno durante 12 días para aumentar el diámetro de la cavidad abdominal y regresar el contenido del saco a su lugar. Se efectuó laparotomía exploratoria y hernioplastia con resultado satisfactorio y seguimiento por consulta externa durante 2 meses, sin alteraciones.


The case report of a 58 years patient with personal history of a poor controlled congestive heart failure is described, who went to the emergency service of Luis Bernaza Hospital in Guayaquil, Ecuador, due to a diffuse abdominal pain, constipation and giant inguinoescrotal mass. The pertinent studies were carried out and a giant inguinoescrotal hernia is diagnosed with home loss, without data of intestinal obstruction. The Goñi Moreno technique was used during 12 days to increase the diameter of the abdominal cavity and return the content from the sack to its place. An exploratory laparotomy and hernioplastia were carried out with satisfactory result and follow up in the outpatient department during 2 months, without alterations.

ABSTRACT

RESUMEN La resección gástrica atípica ha demostrado ser beneficiosa para tumores submucosos. La técnica pre senta mayor riesgo cuando estos se desarrollan próximos a la unión esófago-gástrica (UEG). Para esta limitación se propuso la resección intragástrica mediante una técnica mixta combinando laparoscopia y endoscopia. En nuestro medio no existen publicaciones al respecto. Se trata de una mujer de 42 años, con lesión subepitelial-subcardial de 2 cm, evaluada mediante videoendoscopia alta (VEDA), compa tible con tumor del estroma gastrointestinal (GIST) evaluado mediante ecoendoscopia. La lesión fue resecada mediante abordaje combinado laparoendoscópico. Bajo visión laparoscópica se introdujeron en cavidad abdominal trocares con balón, y bajo visión endoscópica intragástrica se introdujeron estos en el estómago y se fijó la pared gástrica a la pared abdominal insuflando dichos balones. Posterior mente se realizó la resección de la lesión con sutura mecánica. El abordaje combinado es seguro y eficaz, simple en manos entrenadas, pero constituye una opción reproducible en casos seleccionados.


ABSTRACT Atypical gastric resection has proved to be beneficial to treat submucosal tumors. The technique is more difficult when these tumors develop next to the gastroesophageal junction (GEJ). Intragastric resection combining endoscopic and laparoscopic approach was proposed to solve this limitation. There are no publications about this technique in our environment. A 42-year-old female patients with a 2-mm subepithelial tumor below the cardia evaluated by upper gastrointestinal (UGI) videoendoscopy and endoscopic ultrasound suggestive of a gastrointestinal stroma tumor (GIST) underwent resection using the combined laparo-endoscopic approach. Under laparoscopic guidance, balloon-tipped trocars were introduced in the abdominal cavity and then into the stomach using endoscopic view. The balloons were inflated to fix the gastirc wall to the abdominal wall. The lesion was resected using mechanical stapler. The combined approach is safe and efficient, and simple to perform for trained professionals, constituting a reproducible option in selected cases.

Objetivo: Caracterizar morbimortalidad de las reintervenciones de la cirugía abdominal urgente y electiva en el servicio de cirugía general del Hospital Universitario "Manuel Ascunce Domenech". Métodos: Se realizó un estudio observacional descriptivo transversal, de los pacientes que requirieron de reintervención quirúrgica abdominal. El universo estuvo conformado por 236 pacientes que cumplieron con los criterios de inclusión. Se utilizaron métodos estadísticos descriptivos y cálculos con valores porcentuales. Resultados: Predominó el grupo de edades de 40-49 años, así como el sexo masculino, con un 25 por ciento y 64,8 por ciento, respectivamente. En cuanto al tiempo en que se realizó la reintervención 72,5 por ciento se realizó luego de las 48 horas. El 88,6 por ciento de los pacientes resolvió la causa que lo originó en la primera reintervención. Las causas más frecuentes fueron la peritonitis generalizada seguida de los abscesos intrabdominales con un 19,5 por ciento y 17,4 por ciento respectivamente. La mortalidad fue de 30,1 por ciento y el tromboembolismo pulmonar la causa directa de muerte en 12,3 por ciento de los casos. Conclusiones: Casi la totalidad de los casos fueron reintervenidos luego de las 48 horas y las dos terceras partes resolvieron en la primera intervención. La peritonitis generalizada y los abscesos intrabdominales fueron la causa de la reintervención en un número importante(AU)


Introduction: Abdominal surgery re-interventions cause high mortality in general surgery services. Objective: To characterize morbidity and mortality of urgent and elective abdominal surgery re-interventions in the general surgery service of Manuel Ascunce Domenech University Hospital. Methods: A cross-sectional, descriptive, observational study was carried out with patients who required abdominal surgical re-intervention. The universe consisted of 236 patients who met the inclusion criteria. Descriptive statistical methods and calculations with percentage values were used. Results: There was a predominance of the age group 40-49 years and the male sex, accounting for 25 percent and 64.8 percent, respectively. Regarding time of performance of re-intervention, 72.5 percent was carried out after 48 hours. 88.6 percent of the patients had, in the first re-intervention, a solution for the cause that originated it. The most frequent causes were generalized peritonitis, followed by intraabdominal abscesses, accounting for 19.5 percent and 17.4 percent, respectively. Mortality was 30.1 percent and pulmonary embolism was the direct cause of death in 12.3 percent of cases. Conclusions: Almost all the cases were re-intervened after 48 hours and two thirds had a solution the first re-intervention.

ABSTRACT

Introducción: Resulta difícil diagnosticar con certeza la necesidad de reoperar a un paciente después de cirugía abdominal mayor. Objetivo: Evaluar la validez de tres procedimientos para la predicción de la reoperación en cirugía abdominal. Métodos: Estudio explicativo, de cohorte, prospectivo, realizado de noviembre de 2016 a abril de 2017; 146 pacientes en posoperatorio de cirugía abdominal mayor, ingresados consecutivamente en la unidad de cuidados intensivos del Hospital Militar Central Dr. Carlos J. Finlay. Para ser reoperados, los pacientes fueron evaluados según criterios clínicos, de laboratorio e imágenes. De forma independiente, se estimó la probabilidad de requerir una reoperación mediante el Acute Re-intervention Predictive Index, el Sistema de Ayuda al Pronóstico de Reoperación en Cirugía Abdominal (SAPRCA) y la presión intraabdominal. Se aplicó la curva característica operativa del receptor y se seleccionó el mejor punto de corte con sus indicadores de validez. Resultados: Fueron reoperados 23 pacientes (15,8 por ciento). El área bajo la curva característica operativa del receptor (ABC) de los tres puntajes fue > 0,8, con excelente capacidad de discriminación, pero con diferencias significativas entre ellas (p < 0,001). El SAPRCA tuvo mejor desempeño (ABC = 0,965; CI 0,933 - 0,997), seguido de la presión intraabdominal (ABC = 0,939; CI 0,892 - 0,987) y el Acute Re-intervention Predictive Index (ABC = 0,863, CI 0,789 - 0,938). Conclusiones: El SAPRCA mostró un excelente desempeño y una eficacia superior a la demostrada por los otros dos procedimientos, que lo hace recomendable para pronosticar la necesidad de reoperar después de cirugía abdominal mayor(AU)


Introduction: It is difficult to diagnose with certainty the need to reoperate a patient after major abdominal surgery. Objective: To assess the validity of three procedures for predicting reoperation in abdominal surgery. Method: Explanatory, cohort, prospective study, from November 2016 to April 2017, 146 patients in postoperative period of major abdominal surgery, consecutively admitted to the intensive care unit of the Hospital "Carlos J Finlay". To decide on reoperation, patients were evaluated according to clinical, laboratory and imaging criteria. Independently, the probability of requiring a reoperation was estimated using the Acute Re-intervention Predictive Index, the Abdominal Surgery Reoperation Prognosis Aid System and intra-abdominal pressure. To analyse their usefulness, the Receiver Operating Characteristic curve was applied and the best cut-off point with its validity indicators was selected. Results: 23 patients (15.8 percent) were reoperated. The area under the receiver operator curve (AUC) of the three scores was above 0.8, with an excellent ability to discriminate between patients who really required reoperation and those who did not, but with significant differences between them (p <0.001). The Abdominal Surgery Reoperation Prognosis Aid System had the best performance, with an AUC = 0.965 (CI 0.933-0.997), followed by the intra-abdominal pressure (AUC = 0.939, CI 0.892-0.987) and the Acute Re-intervention Predictive Index (AUC = 0.863, CI 0.789-0.938). Conclusions: The Abdominal Surgery Reoperation Prognosis Aid System shows an excellent performance and an efficiency superior to that demonstrated by the other two procedures, which makes it recommendable to predict the need to reoperate after major abdominal surgery(AU)

ABSTRACT

This study aimed to evaluate the appropriate sites of abdominocentesis for peritoneal fluid collection in cattle and to investigate the time of cell viability in vitro, comparing three methods of sample conservation. Twenty-one healthy cattle (19 females and 2 males) were subjected to a laparocentesis procedure to obtain peritoneal fluid, with punctures in three defined sites: left cranial, right cranial, and right caudal. The total peritoneal fluid collected was divided into three aliquots and maintained under three preservation conditions: room temperature (26°C), refrigeration (4°C), and room temperature (26°C) with the addition of 1µL of 10% formaldehyde per 1mL of peritoneal fluid. The peritoneal fluid analysis performed immediately after collection consisted of: physical examination (color, appearance, volume, and specific gravity), biochemical measures (pH, total protein, fibrinogen, creatinine, and glucose), and cellularity (total and differential counts). The determination of proteins and the examination of cells were repeated in each separate aliquot at two, four, six, and eight hours after harvest. Data were analyzed through repeated measures ANOVA or Friedman test. The harvest was productive in 67% of cattle. The left cranial and the right cranial puncture sites were the most appropriate. Peritoneal fluid analyzed after collection, the total protein concentration ranged from 1.4 to 3.6g/dL, and number of leukocytes ranged from 54 to 1,322 cells/µL; 60 to 95% of leukocytes were lymphocytes. The protein concentration decreased, but the absolute values of leukocytes, lymphocytes, and segmented neutrophils did not change up to eight hours after collection, independent of the maintenance method. Cell lysis was delayed by cooling, and the addition of formaldehyde did not help preserve the integrity of cellular morphology. Laparocentesis is a safe and secure procedure in cattle and maybe more productive when performed in specific sites on the left or right sides of the cranial abdominal wall. Peritoneal fluid samples may be analyzed with reliable results for up to eight hours after collection when kept refrigerated and for up to six hours when kept at room temperature.(AU)


O estudo teve como objetivo avaliar os locais adequados de laparocentese para a colheita de fluido peritoneal de bovinos e estabelecer o tempo de viabilidade celular in vitro, comparando três métodos de conservação. Vinte e um bovinos hígidos (19 fêmeas e 2 machos) foram submetidos ao procedimento de laparocentese para obtenção de fluido peritoneal, com punção em três pontos definidos: cranial esquerdo, cranial direito e caudal direito. O volume total do líquido peritoneal foi dividido em três alíquotas mantidas sob três métodos de conservação: temperatura ambiente (26°C); refrigeração (4°C); e temperatura ambiente (26°C) com adição de 1µL de formol 10% para cada 1mL de líquido peritonial. A análise do líquido peritoneal realizada imediatamente após sua obtenção consistiu em: exames físico (cor, aspecto, volume e densidade); bioquímicos (pH, proteína total, fibrinogênio, creatinina e glicose); e da celularidade (contagens total e diferencial). A determinação de proteínas e o exame da celularidade foram repetidos, em cada alíquota separada, as duas, quatro, seis e oito horas após a colheita. Análise de variâncias de medidas repetidas ou teste de Friedman foram empregados para avaliação ao longo do tempo. A colheita foi produtiva em 67% dos bovinos e os locais de punção craniais esquerdo e direito foram os mais adequados. A concentração de proteína total variou de 1,4 a 3,6g/dL e o número de leucócitos de 54 a 1.322 células/µL, com predomínio de linfócitos (60 a 95% das células) no fluido peritoneal analisado logo após a colheita. A concentração de proteínas diminuiu, mas os valores absolutos de leucócitos, de linfócitos e de neutrófilos segmentados não se modificaram até oito horas após a colheita, independente do método de manutenção das amostras. A lise celular foi retardada pela refrigeração e a adição de formol não contribuiu para preservar a integridade da morfologia celular. A laparocentese é um procedimento seguro e de execução fácil em bovinos sendo mais produtiva quando realizada em locais específicos à esquerda ou à direita craniais da parede abdominal. Amostras de fluido peritoneal podem ser analisadas com resultados confiáveis quando mantidas refrigeradas por até oito horas após a colheita e quando mantidas à temperatura ambiente por até seis horas.(AU)

ABSTRACT

ABSTRACT Background: Laparoscopic liver resection is performed worldwide. Hemorrhage is a major complication and bleeding control during hepatotomy is an important concern. Pringle maneuver remains the standard inflow occlusion technique. Aim: Describe an extracorporeal, efficient, fast, cheap and reproducible way to execute the Pringle maneuver in laparoscopic surgery, using a chest tube. Methods: From January 2014 to March 2020, our team performed 398 hepatectomies, 63 by laparoscopy. We systematically encircle the hepatoduodenal ligament and prepare a tourniquet to perform Pringle maneuver. In laparoscopy, we use a 24 Fr chest tube, which is inserted in the abdominal cavity through a small incision. We thread the cotton tape through the tube, pulling it out through the external end, outside the abdomen. To perform the tourniquet, we just need to push the tube as we hold the tape, clamping both with one forceps. Results: The 24 Fr chest tube is firm and works perfectly to occlude blood inflow as the cotton band is tightened. It has an internal diameter of 5,5 mm, sufficient for a laparoscopic grasper pass through it to catch the cotton band, and an external diameter of 8 mm, which allows to be inserted in the abdomen through a tiny incision. The cost of this tube and the cotton band is less than US$ 1. No complications related to the method were identified in our patients. Conclusions: The extracorporeal Pringle maneuver presented here is a safe, cheap and reproducible method, that can be used for bleeding control in laparoscopic liver surgery.


RESUMO Racional: Ressecções hepáticas laparoscópicas são realizadas em todo mundo. A hemorragia é complicação grave e o controle do sangramento durante a hepatotomia é preocupação importante. A manobra de Pringle continua sendo a técnica padrão de oclusão do influxo sanguíneo. Objetivo: Descrever uma maneira eficiente, rápida, barata e reproduzível de executar a manobra de Pringle extracorpórea, em operação laparoscópica, utilizando um dreno de tórax. Métodos: De janeiro/2014 a março/2020, realizamos 398 hepatectomias, 63 por laparoscopia. Nós sistematicamente laçamos o ligamento hepatoduodenal e preparamos um torniquete para a manobra de Pringle. Na laparoscopia, usamos um dreno de tórax 24 Fr, inserido na cavidade abdominal através de uma pequena incisão. Passamos a fita de algodão através do tubo, puxando-a pela extremidade externa, fora do abdome. Para apertar o torniquete, basta pressionar o tubo enquanto seguramos a fita, prendendo ambos com uma pinça. Resultados: O dreno de tórax 24 Fr é firme e funciona perfeitamente para ocluir influxo de sangue, à medida que apertamos o torniquete. Tem diâmetro interno de 5,5 mm, suficiente para passar uma pinça laparoscópica e puxar a fita de algodão, e um diâmetro externo de 8 mm, permitindo a inserção no abdome através de uma pequena incisão. O custo do tubo e fita é inferior a US$ 1, valor insignificante. Não foram identificadas complicações relacionadas ao método em nossos pacientes. Conclusões: A manobra extracorpórea de Pringle apresentada aqui é método seguro, barato e reproduzível, que pode ser utilizado para o controle do sangramento em hepatectomias laparoscópicas.

ABSTRACT

Resumen El presente artículo tiene como finalidad realizar una revisión bibliográfica acerca del síndrome compartimental abdominal en el paciente pediátrico, para actualizar a la población médica general respecto al tema en cuestión; debido a que no hay actualmente estudios de peso estadístico en cuanto a la patología; además, no hay estudios recientes a nivel nacional. El síndrome compartimental abdominal es una condición clínica seria, que presenta una mortalidad elevada sobre todo en la población pediátrica. El desconocimiento de la patología es el principal factor determinante en la mortalidad; ya que, es fundamental la sospecha médica oportuna para inicio de medidas terapéuticas evitando disfunción orgánica y muerte. Por lo tanto, en el siguiente trabajo, se desarrollarán los puntos fundamentales sobre su incidencia, presentación clínica, factores de riesgo, fisiopatología, abordaje diagnóstico y los distintos abordajes terapéuticos, tanto médicos como quirúrgicos; así como, complicaciones y pronósticos. Sin olvidar el punto clave que es conocer la técnica para la medición de la presión intraabdominal, lo que posibilita la detección precoz de complicaciones y consecuentemente, un accionar terapéutico oportuno.


Abstract The purpose of this article is to carry out a bibliographic review about abdominal compartment syndrome in the pediatric patient, to update the medical population about this topic, because currently there are no studies with enough statistical weight about this pathology. Furthermore, there aren´t recent studies at the national level. Abdominal compartment syndrome is a serious clinical condition that has an elevated mortality rate, especially in the pediatric population. The ignorance of the pathology it is the main determining factor in mortality because it is fundamentally the timely medical suspicion to start therapeutic measures avoiding organ dysfunction and death. Therefore, in the following work, the fundamental points will be developed about its incidence, clinical presentation, risk factors, pathophysiology, diagnosis, approach and the different therapeutic approaches medical and surgical as well as complications and prognosis. Without forgetting the key point which is knowing the technique for the measurement of intra abdominal pressure, which will allow the early detection of complications and consequently, a timely therapeutic action.

ABSTRACT

La presencia del apéndice cecal en el saco de una hernia inguinal se denomina hernia de Amyand1,2. Su incidencia varía ‒según distintos autores‒ del 0,13% al 1,7%. Es una rara patología que se diagnostica intraoperatoriamente, ya que su diagnóstico preoperatorio es excepcional. No obstante, en citas bibliográficas se han descripto pocos casos de diagnóstico intraoperatorio, por lo que es importante tener la sospecha clínica en hernias incarceradas de cara al diagnóstico diferencial y a valorar la solicitud de estudios diagnóstico. Su tratamiento es la apendicectomía o reducción del apéndice cecal a la cavidad abdominal asociada a herniorrafia o hernioplastia³.


Amyand’s hernia is defined as an inguinal hernia containing the vermiform appendix1,2. This rare condition, with an incidence between 0.13% and 1.7%, is diagnosed during surgery, as the preoperative diagnosis is exceptional. Few cases of intraoperative diagnosis have been described in the literature. The diagnosis should be suspected in cases of incarcerated hernias so as to order the specific tests. The surgical management includes appendectomy or appendix reduction to the abdominal cavity associated to mesh repair or primary hernia repair without mesh³.

ABSTRACT

In view of the scarcity of data about the topography and syntopy of abdominopelvic viscera of the giant anteater (Myrmecophage tridactyla - Linnaeus, 1758), the present study aimed to elucidate these characteristics and to compare them with the other animal species, especially the domestic ones. Three specimens, two males and one female, were donated by the Environmental Military Police of Franca to the Anatomy Veterinary Laboratory of the University of Franca, after death by road killings. The animals were fixed and maintained in aqueous 10% formaldehyde solution, followed by conventional dissection of the abdominopelvic cavities for subsequent direct inspection and topographic description of the viscera, aiming at comparative analyzes with other species, whose positioning and particularities are already established in the literature. It was observed that most of the viscera of these cavities have similar location and syntopy to domestic animals, except for the kidneys and testicles. In view of the established methodology and the results obtained, it is accepted that more specimens of anteater, both genera, should be evaluated and registered scientifically to confirm the data of the current research and anatomical preconization of the abdominopelvic cavity, inasmuch anatomical individual variation are possible between animals of the same species.(AU)


Diante da escassez de dados sobre a topografia e a sintopia das vísceras abdominopélvicas do tamanduá-bandeira (Myrmecophage tridactyla - Linnaeus, 1758), o presente estudo teve como objetivo elucidar essas características e compará-las com as demais espécies animais, mormente as domésticas. Utilizaram-se três espécimes, dois machos e uma fêmea, provenientes de doação da Polícia Militar Ambiental de Franca ao Laboratório de Anatomia Veterinária da Universidade de Franca, após óbitos por atropelamentos. Os animais foram fixados e mantidos em solução aquosa de formaldeído a 10%, seguidos de dissecação convencional das cavidades abdominopélvicas para posterior inspeção direta e descrição topográfica das vísceras, visando a análises comparativas com outras espécies, cujo posicionamento e cujas particularidades já são bem estabelecidos na literatura. Observou-se que a maioria das vísceras dessas cavidades possuem localização e sintopia similares aos animais domésticos, exceto os rins e os testículos. Diante da metodologia estabelecida e dos resultados obtidos, admite-se que mais espécimes de tamanduás-bandeiras, de ambos os gêneros, devam ser avaliados e registrados cientificamente, visando à confirmação dos dados da atual pesquisa e à preconização anatômica da cavidade abdominopélvica, visto que variações anatômicas individuais são passíveis entre animais da mesma espécie.(AU)

ABSTRACT

Solitary fibrous tumor (SFT) is a rare mesenchymal neoplasm first described and often encountered in the pleura. It has also been documented in a variety of extrapleural sites including the abdominal cavity, respiratory tract, lung, breast, and rarely in the head and neck region. SFT in the hard palate is an extremely unusual location. We present a rare case of SFT that presented as a palate mass, which was suggested as a mesenchymal cell neoplasm by preoperative punch biopsy, and finally diagnosed as STF after successful surgical excision. SFTs should be considered as a differential diagnosis of palate benign tumor when preoperative pathologic findings show mesenchymal neoplasms of fibroblastic or myofibroblastic origin. Possible malignant variants should be distinguished by evaluating the histological parameters, including high cellularity, frequent mitotic activity, nuclear pleomorphism, and presence of necrosis.

ABSTRACT

Chyle only occurs in the peritoneal cavity or around the pericardium through damage to the lymph nodes or improper drainage of the lymph and is characterized by a colostrum-like color and being rich in triglyceride. We encountered a case of a newborn infant with abdominal distention and further diagnosed chylous ascites and hydrocele by inspecting and analyzing the fluid obtained from the abdominal cavity and scrotum. Additionally, a lymphoscintigraphy was performed, which showed a decrease in the uptake of radioactive isotopes in the left iliac nodes and a delayed appearance. Here, we report a case of chyle diagnosed through puncture analysis and its subsequent successful treatment.

ABSTRACT

With the advances in hepatocellular carcinoma (HCC) treatment, the lung metastasis of HCC is becoming increasingly important. In treating the lung metastasis of HCC, a multidisciplinary approach can lead to better results than systemic chemotherapy alone. Here, we report on a patient who presented with pulmonary masses, while the HCC was being controlled in the abdominal cavity. The presence of nontuberculous mycobacteria was identified during the diagnosis of the pulmonary masses. The pulmonary metastases of HCC were treated with a combination of angiotherapy, radiation therapy, and radiofrequency ablation. The patient showed a satisfactory progress with this multidisciplinary localized treatment. We report the clinical progress and review the recent literature regarding the treatment of pulmonary metastasis without intrahepatic HCC herein.

ABSTRACT

OBJECTIVE: Poly (ADP-ribose) polymerase (PARP) is an important molecule in the early stress response of DNA damage, which is involved in DNA damage repair and cellular senescence. Olaparib, as PARP inhibitor, has an anti-tumor effect on high grade serous ovarian cancer, but its effects on cellular senescence have not been reported. This study intends to explore the role of olaparib in the regulation of senescence in ovarian cancer cells. METHODS: The effects of olaparib on the senescence of ovarian cancer cells were detected by using the senescence-associated β-galactosidase (SA-β-Gal) and senescence-associated heterochromatin aggregation (SAHF). Quantitative real-time polymerase chain reaction was used to analyze the senescence-associated secretory phenotype (SASP). Cell cycle and apoptosis were detected by flow cytometry. The effect of olaparib on tumor growth was analyzed in a nude mouse xenograft transplantation model. RESULTS: Long-term (6 days) treatment with olaparib (5 μM) significantly inhibited the growth of ovarian cancer cells, leading to arrest the cell cycle at G0/G1 phase, significant increase the number of positive SA-β-Gal stained cells and positive SAHF cells. The expression of P16 and retinoblastoma protein (p-RB) were significantly enhanced in SKOV3 cells under olaparib treated, meanwhile, the expression of P53 and p-RB were upregulated in A2780 cells. In OVCAR-3 cells, the expression of P53 was downregulated and p-RB was upregulated. Mice with SKOV3 xenograft transplantation was given olaparib (10 mg/kg/day) via abdominal cavity administration, the tumor volume was reduced (p < 0.01). CONCLUSION: Continuous low dosage administration of olaparib induced senescence under P16 or P53 dependent manner in ovarian cancer.

ABSTRACT

PURPOSE: To determine the MR parameters affecting India ink artifacts on opposed-phase chemical shift magnetic resonance (MR) imaging.MATERIALS AND METHODS: The use of a female Sprague-Dawley rat was approved by our Institutional Animal Care and Use Committee. Using an iterative decomposition of water and fat with echo asymmetry and least-squares estimation (IDEAL) images, which is a modified Dixon method, axial opposed-phase images of the abdominal cavity were obtained with different MR parameters: series 1, different repetition times (TRs; 400, 2000, and 4000 ms); series 2, different echo times (TEs; 10, 50, and 100 ms); series 3, different field of views (FOVs; 6, 8, 16, and 24 cm); series 4, different echo train lengths (ETLs; 2, 4, and 8); series 5, different bandwidths (25, 50, and 85); and series 6, different slice thicknesses (1, 2, 4, 8, and 16 mm). Artifacts on opposed images obtained with different parameters were compared subjectively by two radiologists. For objective analysis, the thickness of the artifact was measured. Spearman's correlation between altered MR parameters and thicknesses of India ink artifact was obtained via objective analysis.RESULTS: India ink artifact was increasingly apparent using shorter TE, larger FOV and ETL, and thicker slices upon subjective analysis. The objective analysis revealed a strong negative correlation between the thickness of the artifact and TE (r = -0.870, P < 0.01); however, strong positive correlations were found between FOV (r = 0.854, P < 0.01) and slice thickness (r = 0.971, P < 0.01).CONCLUSION: India ink artifact was thicker with shorter TE, larger FOV, and larger slice thickness.

ABSTRACT

Anisakidosis is a term that collectively refers to a human infection caused by larvae of the family Anisakidae. Because Anisakis simplex was the main cause, it was originally called anisakiasis or anisakiosis, but since other parasites such as Pseudoterranova decipiens also cause similar diseases, the family name is now used as the diagnostic name. Anisakidosis cases have been increasing steadily owing to the propagation of the Japanese raw-fish-eating culture, such as sushi and sashimi, around the world; the traditional raw-fish-eating habits of individual countries; the establishment of marine mammal protection laws; and the development of endoscopic diagnostic techniques. The disease continues to occur in Korea, where most human parasites are believed to have been eradicated and is probably the most common parasitic disease encountered in clinical practice. Anisakidosis is a disease associated with acute abdominal pain. Anisakid larvae can invade the entire digestive tract and abdominal cavity and cause abdominal pain and a variety of digestive system symptoms. Thus, the history of eating raw fish is very important for its differential diagnosis. The lack of a precise understanding of the pathogenesis and clinical course of this disease may lead to unnecessary surgery. Anisakidosis may also manifest as allergic symptoms. Therefore, it is necessary to understand anisakidosis from the perspective of public health, food hygiene, and preventive medicine.

ABSTRACT

RESUMEN El Cáncer de Ovario Epitelial es la novena causa de cáncer en la mujer y la neoplasia ginecológica más letal en países desarrollados. La mayoría de las pacientes son diagnosticadas en etapa avanzada de la enfermedad debido a la ausencia de síntomas específicos. La cirugía y la quimioterapia cumplen un rol fundamental en el tratamiento de esta enfermedad. En pacientes con enfermedad avanzada (estadios III - IV) al momento del diagnóstico, la extirpación de todo tumor macroscópico (citorreducción óptima) ha demostrado ser el factor pronóstico más importante, demostrando un beneficio tanto en tiempo libre de enfermedad como en sobrevida global. Nuestro objetivo es describir, desde una perspectiva multidisciplinaria, los aspectos técnicos más relevantes de la citorreducción del abdomen superior para aquellas pacientes con neoplasias de origen ginecológico.


ABSTRACT Epithelial Ovarian cancer is the ninth most frequent cancer in women and the most lethal gynecologic malignancy in developed countries. The majority of patients are diagnosed in advanced stage of the disease due to the lack of specific symptoms. Surgery and systemic treatment play a key role in the treatment of this disease. For those patients with advanced stage at the time of diagnosis (III - IV), removal of all macroscopic disease (optimal cytoreduction) has been shown as the most important prognostic factor, demonstrating improvement not only in progression free survival but also in overall survival. Our aim is to describe, in a multidisciplinary fashion, the most relevant aspect about oncological debulking procedures in the upper abdominal cavity for women with gynecological malignancies.

ABSTRACT

Abstract Purpose: To develop and test a model of teaching by means of an abdominal cavity simulator. Methods: This study had two stages: development of a teaching model and an experimental prospective study that aimed to evaluate the residents' competence. The participants were divided into 3 groups: first-year resident, second-year resident, and senior surgeon. The two groups of resident physicians received training in the simulator, under instructor supervision for skill acquisition, according to the model proposed in first stage. The surgeons did not receive this intervention. The correlations and associations were verified through simple and multiple linear regressions. The learning curves were analysed using Cox regression models. The impact of the epidemiological characteristics was tested. Results: All residents reached the maximum score at the end of 16 steps and were comparable to the experimental (p<0.001). Conclusion: Residents who underwent training using the methodology of the proposed teaching model, which is based on realistic simulation, acquired proficiency in the accomplishment of endosutures in up to 16 hours of training in the laboratory.

ABSTRACT

Most of the intra-abdominal infections are benign and critical diseases caused by trauma, surgery and gastrointestinal diseases, which require the attention of surgeons. The increase of drug resistance of pathogens is a common clinical problem. The intra-abdominal infection caused by multidrug-resistant bacteria is a huge challenge faced by clinicians, and is mainly found in hospital-acquired abdominal infections, of which gram-negative bacteria are the most common. This paper firstly summarizes the common types, early diagnosis and risk factors of multidrug-resistant bacteria according to the literature, and then describes the treatment strategy of intra-abdominal infection caused by multidrug-resistant bacteria from four aspects: anti-infective medication, infection source control, resuscitation and organ support, and nutritional support treatment. In addition, we should promote gastrointestinal function recovery through nutritional support treatment and prevent intestinal source infection, on the basis of understanding the risk factors of multidrug-resistant infection, rational use of anti-infective medication and infection source control measures. At the same time, proper organ function support can help to improve the success rate in the treatment of multidrug-resistant intra-abdominal infection.
