Páncreas ectópico, una posible y rara causa de hipoglucemia postprandial / Ectopic pancreas, a possible rare cause of postprandial hypoglycemia

Introducción: El páncreas ectópico es la segunda anomalía congénita pancreática más frecuente después del páncreas divisum. Fue descrito por primera vez en 1729 por Schultz y se define como la presencia de tejido pancreático que carece de comunicación anatómica o vascular con el cuerpo principal del páncreas. La localización más frecuente es en el estómago (25 - 38 por ciento), seguido de duodeno, yeyuno e íleon. El 40 por ciento de los casos son sintomáticos y es más frecuente su presentación en varones en torno a la 5ª y 6ª década de la vida. Objetivo: Presentar un caso de páncreas ectópico diagnosticado a través de un estudio histológico tras realizada la cirugía. Presentación de caso: Presentamos el caso de una paciente compatible con hipoglucemia y cuyo estudio definitivo mostró la presencia de tejido pancreático ectópico en estómago, con resolución completa de los síntomas tras tratamiento quirúrgico. La anatomía patológica mostró una lesión nodular tumoral benigna (2,5 cm), constituida por tejido pancreático heterotópico, con presencia de páncreas exocrino con acinos. Páncreas endocrino con presencia de islotes de Langerhans y componente epitelial con ductos. Afectación desde la submucosa hasta la subserosa, con una pared muscular propia con hiperplasia muscular en relación a la heterotopía pancreática. La mucosa gástrica mostraba inflamación crónica leve con escasos folículos linfoides. Conclusiones: La presencia de páncreas ectópico es una entidad poco frecuente, pero a tener en cuenta en pacientes con clínica de hipoglucemia, una vez descartadas otras causas. No existe consenso con respecto a indicaciones en el manejo de lesiones pequeñas y asintomáticas, por lo que se recomienda individualizar cada caso teniendo en cuenta el tamaño, la localización y el tipo histológico(AU)

Introduction: Ectopic pancreas is the second most frequent congenital anomaly after pancreas divisum. It was described for the first time in 1729 by Schultz and it is defined as the presence of pancreatic tissue with no anatomical or vascular communication with the main body of pancreas. The most common location is in the stomach (25-38 percent), followed by the duodenum, jejunum and ileum ones. 40 percent of the cases are symptomatic and is more frequent their presentation in males in the fifth or sixth decade of life. Objective: To present a case of ectopic pancreas diagnosed through a histological study after surgery. Case presentation: Case of a patient with clinical features compatible with hypoglycemia that after being studied showed the presence of ectopic pancreatic tissue in the stomach, with a complete solution of the symptoms after surgical treatment. The pathological anatomy showed a benign tumor nodular lesion (2.5 cm), made up of heterotopic pancreatic tissue, with the presence of exocrine pancreas with acini. Endocrine pancreas with the presence of islets of Langerhans and epithelial component with ducts. Involvement from the submucosa to the subserosa, with a proper muscular wall with muscular hyperplasia in relation to pancreatic heterotopia. The gastric mucosa showed mild chronic inflammation with few lymphoid follicles. Conclusions: The presence of ectopic pancreas is a rare condition, but it should be taken into account in patients with clinical features of hypoglycemia once ruled out other causes. There is no consensus in regards to the indications for the management of small and asymptomatic lesions, so, it is recommended to individualize each case taking into account the size, location and histological type(AU)

Perforación gástrica asociada al consumo de helado con nitrógeno líquido / Gastric perforation associated with the intake of ice cream with liquid nitrogen

La ingestión de nitrógeno líquido es una causa infrecuente de perforación gástrica, se conoce poco sobre como este compuesto afecta el tejido gastrointestinal, sus mecanismos de lesión y sus consecuencias clínicas. Cada vez es más frecuente el uso del nitrógeno líquido de forma comercial en productos de repostería y gastronomía, por lo que es importante reconocer sus potenciales efectos cuando la manipulación no es la adecuada. En este caso clínico describimos una perforación gástrica secundaria al consumo de helado preparado con nitrógeno líquido.

Liquid nitrogene ingestion is a frecuent cause of gastric perforation. It is unknown how this compound afects the gatrointestinal tissue, it mechanisisms of injury and the clinical consecuences. Nowadays, the use of liquid nitrogene in gastronomy is becoming a tendency, for this reason it is important to identify the potencial healt effects of this compound when is not correctly manipulated. The following article describes a secondary gastric perforation, as a consecuence of the consumption of ice cream prepared with liquid nitrogene.

Síndrome de Rapunzel gigante con complicación atípica: Reporte de un caso / Giant Rapunzel syndrome with atypical complication: Report of a case

El síndrome de Rapunzel es una forma inusual y rara de tricobezoar gástrico que se extiende al intestino delgado. La formación es debida a la ingestión continua de cabello la cual lleva a la impactación del mismo junto con moco y alimento, pero es infrecuente que se produzca perforación gástrica. Reportamos el caso de una paciente de sexo femenino de 16 años de edad admitida en nuestra institución con antecedentes de depresión y cuadro clínico caracterizado por náuseas, epigastralgia severa y pérdida patológica de peso. Al examen físico se evidenció un abdomen tenso con reacción peritoneal, la tomografía de abdomen contrastada evidenció un estomago distendido con contenido heterogéneo que se extiende hacia el duodeno, hidroneumoperitoneo y líquido en fondo de saco de Douglas, por lo que se le decidió realizar una laparotomía exploratoria que evidenció perforación en cara anterior de estómago que es una complicación infrecuente, por lo que se procedió a la extracción del tricobezoar gigante con extensión duodenal; evolucionando de forma favorable remitiéndose la paciente a controles ambulatorios con psiquiatría; finalmente se le realizó una endoscopía alta a los 6 meses que evidenció la cicatriz del procedimiento quirúrgico.

Rapunzel syndrome is an unusual and rare form of gastric trichobezoar that extends into the small intestine. The formation is due to the continuous ingestion of hair which leads to the impaction of the hair along with mucus and food, but it is rare that gastric perforation occurs. We report the case of a female patient of 16 years of age admitted to our institution with a history of depression and clinical symptoms characterized by nausea, severe epigastralgia and pathological loss of weight. The physical examination showed a tense abdomen with a peritoneal reaction. Contrast-enhanced tomography showed a distended stomach with a heterogeneous content that extended to the duodenum, hydro pneumoperitoneum, Douglas sack bottom liquid, and it was decided to perform an exploratory laparotomy. Showed perforation in the anterior face of the stomach which is infrequent, so we proceeded to the extraction of giant trichobezoar with duodenal extension; Evolving favorably, the patient being referred to outpatient controls with psychiatry; Finally, a high endoscopy was performed at 6 months, which evidenced the scar of the surgical procedure.

Hallazgos endoscópicos en el tubo digestivo secundarios a la ingesta de cáusticos en niños atendidos en el Departamento de Urgencias / Endoscopic findings of the digestive tract secondary to caustic ingestion in children seen at the Emergency Department

Antecedentes. La ingesta de sustancias cáusticas en pediatría constituye una causa frecuente de atención médica en Urgencias. El uso indiscriminado de limpiadores químicos y la facilidad de adquisición son factores determinantes para estas lesiones. Población y métodos. Estudio descriptivo analítico. Se incluyeron niños < 16 años, entre enero de 1998 y diciembre de 2017. Se identificó el agente químico cáustico ingerido por el niño como ácido o alcalino. Se realizó una endoscopía digestiva para tipificar el grado de quemadura. Se comparó el grado de quemadura con el tipo de cáustico; por medio de la prueba de chi² o exacta de Fisher, se consideró significativo el valor de P < 0,05. Resultados. Ingresaron 133 niños en Urgencias por ingesta de cáusticos. El agente cáustico fue ácido en el 41 % y alcalino en el 59 %. El agente ácido más frecuente fue el ácido muriático (36,8 %), mientras que el alcalino fue la sosa (soda) cáustica (41,4 %). La quemadura del esófago fue más frecuente en la ingesta de sosa en comparación con otros cáusticos (p= 0,001), mientras que la quemadura del estómago (p= 0,001) y del duodeno (p= 0,002) fue estadísticamente significativa en la ingesta de ácido muriático. El grupo de edad que más frecuentemente ingirió algún cáustico (93,2 %) fueron los menores de 5 años. Conclusiones. El cáustico ingerido con mayor frecuencia fue un agente alcalino, que provocó quemadura esofágica, mientras que un agente ácido provocó quemaduras en el estómago y el duodeno evidenciadas por endoscopía.

Background. Caustic ingestion in pediatrics is a common cause of visits to the Emergency Department. An indiscriminate use of cleaning chemicals and an easy access to them are determining factors for these injuries. Population and methods. Descriptive, analytical study. Children aged < 16 years hospitalized between January 1998 and December 2017 were included. The ingested caustic substance was identified as acid or alkaline. A gastrointestinal endoscopy was done to establish the burn grade. The grade of the burn was compared to the type of caustic substance using the χ² test or the Fisher's exact test; a P value < 0.05 was considered significant. Results. A total of 133 children were admitted to the Emergency Department due to caustic ingestion. The caustic agent was acid in 41 % of cases and alkaline, in 59 %. The most common acid caustic substance was muriatic acid (36.8 %) and the most common alkaline caustic agent was caustic soda (41.4 %). An esophageal burn was the most common consequence of caustic soda ingestion compared to other caustic agents (p = 0.001), whereas muriatic acid ingestion was the most statistically significant cause of stomach burn (p = 0.001) and duodenal burn (p = 0.002). The age group that most commonly ingested some caustic agent (93.2 %) corresponded to children younger than 5 years. Conclusions. The most common type of ingested caustic agent was alkaline, which caused esophageal burn; whereas, the ingestion of an acid caustic substance caused stomach and duodenal burns, as evidenced by endoscopy.

Pharyngo-ileo-colo-anastomosis with micro-vascular blood supply augmentation for esophago-gastric replacement due to esophago-gastric necrosis after caustic ingestion / Faringo-íleo-colo-anastomose com suprimento sanguíneo microvascular para substituição esofagogástrica por necrose esofagogástrica após ingestão cáustica

ABSTRACT Background : Complete esophago-gastric necrosis after caustic ingestion is a challenging surgical scenario for reconstruction of the upper digestive transit. Aim : To present a surgical technique for reconstruction of the upper digestive tract after total esophagectomy and gastrectomy due to esophageal and gastric necrosis Method: The transit was re-established by means of a pharyngo-ileo-colic interposition with microsurgical arterial and venous anastomosis for augmentation of blood supply. Colo-duodeno-anastomosis and ileo-transverse colic anastomosis were performed for complete digestive transit reconstruction. Result: This procedure was applied in a case of 41 years male attempted suicide by ingesting alkali caustic liquid (concentrated sodium hydroxide). Total necrosis of the esophagus and stomach occurred, which required initially total esophago-gastrectomy, closure at the level of the crico-pharyngeal sphincter and jejunostomy for enteral feeding with a highly deteriorated quality of life . The procedure was performed later and there were no major early and late postoperative complications and normal nutritional conditions were re-stablished. Conclusion: The procedure is feasible and must be managed by multidisciplinary team in order to re-establish a normal quality of life.

RESUMO Racional: A necrose esofagogástrica completa após ingestão cáustica é um cenário cirúrgico desafiador para a reconstrução do trânsito digestivo alto. Objetivo: Apresentar uma técnica cirúrgica para reconstrução do trato digestivo superior após esofagectomia total e gastrectomia por necrose esofágica e gástrica. Método: O trânsito foi restabelecido por interposição faringo-íleo-cólica com anastomose arterial e venosa microcirúrgica com aumento do suprimento sanguíneo. Adicionalmente, anastomose colo-duodeno-anastomótica e íleo-transversa foram realizadas para reconstrução completa do trânsito digestivo. Resultado: Este procedimento foi aplicado em um homem de 41 anos com tentativa de suicídio pela ingestão de líquido cáustico alcalino (hidróxido de sódio concentrado). Ocorreu necrose total do esôfago e do estômago, o que exigiu inicialmente esofagogastrectomia total, fechamento ao nível do esfíncter cricofaríngeo e jejunostomia para alimentação enteral produzindo qualidade de vida altamente deteriorada. O procedimento foi realizado mais tardiamente e não houve maiores complicações pós-operatórias precoces e tardias e condições nutricionais normais foram restabelecidas. Conclusão: O procedimento é viável e deve ser manejado por equipe multidisciplinar a fim de restabelecer a qualidade de vida normal.

Caustic ingestion in children in south of Iran: Retrospective study from Shiraz - Iran / Ingestión de cáusticos en niños del sur de Irán: Estudio retrospectivo de Shiraz - Irán

Caustic ingestion is a major health concern in both developed and developing countries, that may lead to serious esophageal injury. The clinical presentation of caustic ingestion in children vary from asymptomatic to serious and fatal sequelae, such as perforation and stricture formation. Objective: Due to the lack of a comprehensive study in our area, this study has evaluated clinical and endoscopic manifestations and complications of caustic ingestion in children in south of Iran. Materials and methods: In this retrospective study, we reviewed 75 children with caustic ingestion who admitted in Nemazee Hospital of Shiraz University of Medical Science during 6 years (2006-2011). Sign and symptoms were recorded for each case. Results: The most common symptoms were dysphagia, oral lesions, vomiting, and drooling. Esophageal injuries were detected in both acid and alkali ingestion, but gastric injuries was significantly more in acid ingestion. During follow up period, 20% of all cases developed esophageal stricture. Conclusion: Dysphagia, oral lesions, vomiting, and drooling were the most common findings. Esophageal stricture was found in 20% of cases during 3 months of follow up.

La ingestión de cáusticos es una gran preocupación de salud tanto en países desarrollados como en vías de desarrollo, que puede llevar a lesiones esofágicas graves. La presentación clínica de la ingestión de cáusticos en niños varía desde asintomática hasta tener secuelas fatales, como perforación y/o estenosis. Objetivo: Debido a la ausencia de estudios en nuestra área, este estudio ha evaluado las manifestaciones clínicas, endoscópicas y las complicaciones de la ingesta de cáusticos en niños en el sur de Irán. Materiales y métodos: En estudio retrospectivo, revisamos 75 niños con ingesta de cáusticos que ingresaron al Nemazee Hospital of Shiraz University of Medical Science durante 6 años (2006-2011). Los signos y síntomas fueron recolectados para cada caso. Resultados: Los síntomas más frecuentes fueron disfagia, lesiones orales, vómitos y salivación. Las lesiones esofágicas se detectaron tanto en ingestión de ácido como de álcali, pero las lesiones gástricas fueron definitivamente más frecuentes con la ingestión de ácidos. Durante el periodo de seguimiento el 20% de los casos desarrolló estrechez esofágica. Conclusión: La disfagia, lesiones orales, vómitos y salivación fueron los hallazgos más comunes. La estrechez esofágica se encontró en el 20% de los casos durante los tres meses de seguimiento de los pacientes.

Abscesso hepático polimicrobiano por perfuração gástrica por corpo estranho / Polymicrobial hepatic abscess due to gastric perforation by foreign body

Abscesso hepático piogênico é uma condição incomum, com incidência inferior a 1% das internações hospitalares. O abscesso hepático causado por corpo estranho é uma condição extremamente rara, com possibilidade de desfecho fatal devido às dificuldades em se estabelecer o diagnóstico. Relata-se o caso de uma paciente de 52 anos, feminina, com dor abdominal difusa há 1 semana em epigástrio e hipocôndrio direito, associado a diarreia e vômitos há 5 dias e febre de 40°C. Apresentava abdome doloroso, leucocitose de 17.000 p/mm³, bilirrubina total elevada à custa de fração direta, sorologias para HIV 1 e 2 e Hepatite B e C negativas. Em ultrassonografia de abdome total, demonstrou-se imagem heterogênea de 78x61mm em segmento II e III. Na tomografia computadorizada de abdome total observou-se imagem hipodensa, hipovascular, medindo 100x81x78, em lobo hepático esquerdo. Iniciou-se antibioticoterapia empírica e realizou-se drenagem percutânea guiada por ultrassom, demonstrando infecção polimicrobiana em cultura do material. Em ultrassonografia de controle, permanecia área heterogênea, medindo 77x72x49mm em lobo hepático esquerdo. A paciente então foi submetida à laparotomia exploratória, evidenciando no intraoperatório adesão do estômago a parede posterior do fígado. Após descolamento da estrutura, observou-se corpo estranho representado por espinha de peixe no interior do parênquima hepático, oriundo de perfuração da parede anterior do estômago. Embora seja uma etiologia rara, a hipótese diagnóstica de corpos estranhos deve ser considerada em todo caso de abscesso hepático refratário ao tratamento habitual, a fim de reduzir a morbidade e mortalidade do quadro (AU)

Pyogenic hepatic abscess is an uncommon condition, with incidence below 1% of hospitalizations. Hepatic abscess caused by foreign body is an extremely rare condition, with the possibility of fatal outcome due to difficulties in establishing the diagnosis. Here the authors report the case of a 52-year-old female patient with diffuse abdominal pain for one week in the epigastrium and right hypochondrium associated with diarrhea and vomiting for 5 days and fever of 40 °C. She presented painful abdomen, leukocytosis of 17,000 p/mm³, elevated total bilirubin at the expense of direct ratio, and negative serologies for HIV 1 and 2 and Hepatitis B and C. In total abdomen ultrasound, a heterogeneous image of 78x61mm was shown in segment II and III. Computed tomography of the total abdomen showed a hypodense, hypovascular image, measuring 100x81x78mm, in the left hepatic lobe. Empirical antibiotic therapy was initiated and ultrasound-guided percutaneous drainage was performed, demonstrating polymicrobial infection in culture of the material. In control ultrasonography, a heterogeneous area remained, measuring 77x72x49mm in the left hepatic lobe. The patient was then submitted to exploratory laparotomy, with intraoperative evidence of adhesion of the stomach to the posterior wall of the liver. After detachment of the structure, we observed a foreign body represented by fishbone inside the hepatic parenchyma, originating from perforation of the anterior wall of the stomach. Although it is a rare etiology, the diagnostic hypothesis of foreign bodies should be considered in all cases of hepatic abscess refractory to usual treatment, in order to reduce the morbidity and mortality of the condition (AU)

Trichobezoar causing gastric perforation: a case report

Trichobezoars are impactions of swallowed hairs in the stomach and occasionally in the intestine. They occur in emotionally disturbed, depressed, or mentally retarded patients who have trichotillomania and trichophagia. Trichobezoars are usually diagnosed on CT scan or upper GI endoscopy. They can give rise to complications like gastroduodenal ulceration, haemorrhage, perforation, peritonitis, or obstruction, with a high rate of mortality. The treatment is endoscopic, laparoscopic, or surgical removal and usually followed by psychiatric opinion. Herein, we report a case of gastric trichobezoar presenting as gastric perforation in a patient of trichotillomania and trichophagia that was accidentally found on laparotomy. As the patient was in shock on admission, relevant history of trichophagia could not be elicited. Henceforth, she was operated for perforation peritonitis. Trichobezoar was discovered intraoperatively and removed. The perforation was repaired with Graham's omental patch. Postoperatively, history of trichophagia was corroborated with scarring alopecia of scalp. Trichobezoars is usually seen in adolescent girls, often with an underlying psychiatric or social problem. Laparotomy is the gold standard treatment. Surgical treatment should be followed by behavioral and psychiatric treatment. The patient should be vigilantly monitored for this impulsive disorder, as recurrences are common

Sutura endoscópica para perfuração gástrica nos procedimentos cirúrgicos endoscópicos translumenais por orifício natural, utilizando dispositivo T-Tag associado à câmara plástica protetora: factibilidade e resultados - estudo experimental / Endoscopic suturing for gastric perforation in natural orifice translumenal endoscopic surgery procedures, using T-Tag device and a plastic protection chamber: feasibility and results- experimental study

A perfuração gástrica por endoscopia é a consequência de alguns de seus procedimentos, e atualmente, com o advento das cirurgias endoscópicas translumenais por orifícios naturais, um meio de manipulação dos órgãos abdominais. Esse é o motivo pelo qual os endoscopistas estão procurando um reparo endoscópico seguro. O objetivo foi avaliar a factibilidade e os resultados do fechamento da abertura gástrica similar àquelas realizadas nos procedimentos cirúrgicos endoscópicos translumenais por orifícios naturais utilizando-se o T-Tag associado à câmara plástica protetora. Sob anestesia geral, dez porcos Landrace foram submetidos a uma perfuração gástrica calibrada em 18 mm de diâmetro. A abertura foi fechada pelo novo método apresentado, composto de fios cirúrgicos conectados em uma âncora metálica (T-Tag) posicionados pela parede gástrica através de uma agulha. Uma câmara protetora plástica foi adaptada à extremidade distal do endoscópio para proteger os órgãos abdominais adjacentes da punção da agulha fora do estômago. Seis dispositivos T-Tag foram posicionados na maioria dos casos e os fios atados com um apertador de nó metálico endoscópico formando três pontos de sutura. O teste de vazamento foi realizado com uma pinça endoscópica e distensão da câmara gástrica com ar. Os animais receberam líquidos no mesmo dia do procedimento. Uma dose de antibiótico diária por dois dias foi administrada. Nenhuma complicação foi detectada no período pós-operatório. Um mês depois, a endoscopia revelou a presença de cicatriz em todos os animais, e a maioria apresentava materiais da sutura aderidos à superfície mucosa da região. A região do antro gástrico apresentava poucas aderências identificadas na laparotomia realizada no mesmo momento. O reparo endoscópico utilizando o T-Tag e a câmara protetora plástica é factível, fácil de ser realizada e seguro. São necessários estudos adicionais para mostrar o real valor desse tipo de procedimento...

The endoscopic gastric perforation is a consequence of some endoscopic procedures and now a way to manage abdominal organs. This is the reason why endoscopists are studying a safe endoscopic repair. The objective was to evaluate feasibility and results of the gastric opening closure similar to those performed in natural orifice translumenal endoscopic surgery procedures using T-Tag associated with the plastic protection chamber. Ten Landrace pigs underwent a gastric perforation of 1.8 cm in diameter under general anesthesia. The opening was repaired with stitch assembled in a T-Tag anchor placed through the gastric wall with a needle. A plastic transparent chamber, adapted to the endoscope tip protected the abdominal organs from the needle puncture outside the stomach. Six T-Tags were placed in most cases and the stitches were tied with a metallic tie-knot, forming three sutures. The leakage test was performed with a forceps and by air distention. The animals received liquids in the same operative day. One daily shot antibiotic during two days was used. No complication was detected in the postoperative course. One month later the endoscopy revealed a scar in all animals, and the majority of these with suture material. The antral anterior gastric wall was clear with few adhesions in the laparotomy performed in the same time. The endoscopic repair using T-Tag and a protector chamber is feasible, easy to perform and safe. Further studies are needed to show the real value of this kind of procedure...

Intoxicación por ácido fluorhídrico: Presentación de un caso clínico / Hydrofluoric acid poisoning: Case report

El ácido fluorhídrico es una sustancia cáustica muy peligrosa, que tiene aplicaciones industriales y domésticas. Las manifestaciones clínicas asociadas a la intoxicación por este producto dependen de la vía de exposición, la concentración del ácido y la penetrabilidad en el tejido expuesto. En el tubo digestivo, la presencia o la ausencia de síntomas no se correlacionan con la gravedad de la lesión. Es necesario realizar una endoscopia digestiva alta en los pacientes con historia de ingestión de ácido fluorhídrico. Se requiere una inmediata intervención, ya que puede causar toxicidad sistémica. Se presenta el caso de una niña de 5 años que ingirió accidentalmente 5 ml de ácido fluorhídrico al 20%. En la videoendoscopia digestiva alta (VEDA), realizada dentro de las 24 horas, el esófago y el estómago estaban eritematosos, con lesiones erosivas. A los 2 meses se realizó una VEDA de control, que mostró una mucosa normal.

Hydrofluoric acid is a highly dangerous substance with industrial and domestically appliances. Clinical manifestations of poisoning depend on exposure mechanism, acid concentration and exposed tissue penetrability. Gastrointestinal tract symptoms do not correlate with injury severity. Patients with history of hydrofluoric acid ingestion should undergo an endoscopy of the upper gastrointestinal tract. Intoxication requires immediate intervention because systemic toxicity can take place. We present a 5 year old girl who accidentally swallowed 5 ml of 20% hydrofluoric acid. We performed gastrointestinal tract endoscopy post ingestion, which revealed erythematous esophagus and stomach with erosive lesions. Two months later, same study was performed and revealed esophagus and stomach normal mucous membrane.

Cáncer gástrico perforado: estudio clínico-morfológico y pronóstico / Perforated gastric cancer

Background: Perforation is an unusual presentation of gastric cancer. There is disagreement about its prognosis and treatment. Aim: To describe the clinical, morphological, therapeutic and prognostic features of perforated gastric cancer. Material and Methods: Reviewing the registry of a pathology laboratory in a general hospital, 13 patients with perforated gastric cancer, aged 48 to 75 years and operated in a period of 20 years, was identified. The medical records of these patients were reviewed and eventual deaths were identified using death certificates. Results: A gastrectomy was performed in 9 cases and lymph node dissection in six. Seventy eight percent were T4 tumors and all patients in whom a lymph node dissection was done, had lymph node involvement. In 10 cases, the preoperative diagnoses were a perforated peptic ulcer. Mean global survival was six months. The figures for patients subjected or not subjected to gastrectomy were 21.5 and 3.7 months, respectively (p < 0.01). One of five patients subjected to emergency surgery, died. Conclusions: Perforation occurs usually in advanced stages of gastric cancer and older patients. In this report those patients subjected to gastrectomy have a better survival.

Introducción: El cáncer gástrico perforado (CGP) es una infrecuente forma de presentación de la enfermedad. Su pronóstico y manejo quirúrgico son motivo de controversias. El objetivo de este estudio es describir variables clínico-morfológicas de pacientes con CGP junto con valorar el tratamiento e impacto en la supervivencia (SV) de estos pacientes. Material y Método: Estudio de cohorte histórica. Se estudiaron variables clínico-morfológicas, de tratamiento y SV de pacientes con CGP sometidos a cirugía radical o paliativa en el Hospital Hernán Henríquez Aravena de Temuco entre enero de 1986 y diciembre de 2007 (n = 13). Utilizando los paquetes estadísticos Epi-info 6.0 y Stata 9.0, se aplicó estadística descriptiva, analítica y análisis de SV. Resultados: Se constató 13 casos de CGP (1,8 por ciento) con un promedio de edad de 64,2 años (35-75 años). Se efectuó gastrectomía en 9 pacientes (69 por ciento) en 6 de ellos con disección ganglionar. El 78 por ciento correspondió a tumores T4 y todos los casos con disección ganglionar presentaron compromiso de los linfonodos. En 10/13 el diagnóstico pre-operatorio fue úlcera péptica perforada (UPP) permitiendo los hallazgos intra-operatorios sospechar el carácter neoplásico maligno en 10/13 casos. El promedio de SVglobal fue 16 meses, siendo de 21,5 y 3,7 meses (p < 0,001) para el subgrupo sometido a gastrectomía y reparación respectivamente. La mortalidad quirúrgica en sujetos sometidos a gastrectomía de urgencia fue 20 por ciento (1/5). Conclusiones: La perforación gástrica se presenta habitualmente en pacientes mayores y con estadios avanzados de la enfermedad, nuestros pacientes gastrectomizados con intención curativa mostraron mejores resultados de supervivencia.

Schinus terebinthifolius raddi (anacardiaceae) no processo de cicatrização de gastrorrafias em ratos / Schinus terebinthifolius raddi (anacardiaceae) in the healing process of gastrorraphy in rats

RACIONAL: A gastrorrafia isolada ou associada ao uso de adesivos biológicos constituiu ao longo da história da cirurgia a forma usual de promover a cicatrização nas lesões gástricas e o uso de fitoterápicos tem sido cada vez mais empregado. OBJETIVO: Avaliar a cicatrização de ferida provocada no estômago de ratos com uso do extrato hidroalcoólico de Schinus terebinthifolius Raddi. MÉTODOS: Foram utilizados 60 ratos, adultos, machos, distribuídos em dois grupos: grupo aroeira e grupo controle, os quais foram subdivididos em três subgrupos de cinco animais conforme o momento das mortes dos animais (7, 14 e 21 dias). Todos os animais foram submetidos ao mesmo procedimento cirúrgico (lesão e rafia do estômago) diferindo apenas que os animais do grupo aroeira receberam dose diária de 100 mg/kg do extrato hidroalcoólico via gavagem enquanto o grupo controle recebeu solução salina isotônica. Os parâmetros avaliados foram: alterações macroscópicas e microscópicas, teste de resistência à insuflação de ar atmosférico e teste pela força de tração. RESULTADOS: Todos os animais demonstraram boa cicatrização da parede abdominal e das gastrorrafias, sem infecção e deiscência. Ambos os grupos apresentaram aderências à superfície das gastrorrafias com órgãos vizinhos. O teste de resistência por insuflação de ar atmosférico e força de tração mostraram maiores médias de pressão no 7º dia e de força de ruptura nos períodos estudados para o grupo aroeira. A intensidade da inflamação crônica revelou diferença estatisticamente significante nas variáveis proliferação fobrobrástica e colagenização. CONCLUSÃO: O uso do extrato hidroalcoólico de Schinus terebinthifolius Raddi acelerou a cicatrização do estômago de ratos.

BACKGROUND: Gastrorraphy, isolated or associated with the use of biological adhesives, was throughout the history of surgery the usual way to promote healing in gastric lesions and the use of herbal medicine has been increasingly more employed. AIM: To evaluate the wound healing in the stomach of rats with the use of the hydroalcoholic extract of Schinus terebinthifolius Raddi (aroeira). METHODS: Sixty rats, adult males, were divided into two groups: aroeira group and control group. Each one was subdivided into four subgroups of 15 animals (test groups). Each subdivided subgroup was also subdivided into three subgroups of five rats (deaths periods of 7, 14 and 21 days). All animals underwent the same surgical procedure (injury and stomach suture); animals in the aroeira group received daily dose of 100 mg/kg of hydroalcoholic extract via gavage while the control group received isotonic saline solution. Parameters evaluated were: macroscopic and microscopic changes, test for resistance to insufflation of atmospheric air and test for tensile strength. RESULTS: All animals had good healing of the abdominal wall and gastrorraphies without infection and dehiscence. Both groups had adhesions to the gastrorraphies surfaces with neighboring organs. The resistance test by insufflation of atmospheric air and tensile strength showed higher average of pressure on the 7th day and breaking strength in the time periods for the aroeira group. The intensity of chronic inflammation revealed statistically significant differences in the variables fibroblast proliferation and collagen. CONCLUSION: The use of hydroalcoholic extract of Schinus terebinthifolius Raddi accelerated the stomach healing in rats.

Pseudotumor of the Omentum Associated with Migration of the Ingested Crab-Leg

Foreign body ingestion is not uncommon in clinical practice, and it may occasionally lead to penetration injuries. Emergency physicians and radiologists sometimes fail to obtain complete histories including ingestion and may overlook the possibility of foreign body-induced complications. Herein, we report a case of stomach antrum perforation due to foreign body migration. We were unaware of the patient's history of eating the Korean delicacy "Kanjang-gaejang," which is raw crab seasoned with soy sauce. Several imaging diagnostic modalities had suggested the possibility of a malignant mass in the gastrocolic ligament area. During the operation, a crab leg was discovered as the cause of an intra-abdominal abscess. The patient underwent an antrectomy, a vagotomay, and a transverse colon wedge resection. We present this unusual case of a pseudotumorous lesion caused by ingestion of Kanjang-gaejang.

CONTEXT: The endoscopic gastric perforation is a consequence of some endoscopic procedures and now a way to manage abdominal organs. This is the reason why endoscopists are studying a safe endoscopic repair. OBJECTIVE: To evaluate an endoscopic closure method for the gastric opening in natural orifice transenteric surgery DESIGN: Short-term survival animal study. METHODS: Ten White Landrace pigs underwent a gastric perforation of 1.8 cm in diameter under general anesthesia. The opening was repaired with stitch assembled in a T-tag anchor placed through the gastric wall with a needle. A plastic transparent chamber, adapted to the endoscope tip protected the abdominal organs from the needle puncture outside the stomach. Six T-tags were placed in most cases and the stitches were tied with a metallic tie-knot, forming three sutures. The animals received liquids in the same operative day. One shoot antibiotic was used. The leakage test was performed with a forceps and by air distention. RESULTS: No complication was detected in the postoperative course. One month later the endoscopy revealed a scar and some suture material was observed in all animals. The antral anterior gastric wall was clear with few adhesions in the laparotomy performed in the same time. The adhesions were intense in an animal in which a cholecystectomy was performed before the repair. CONCLUSION: The endoscopic repair using T-tag and a protector chamber is feasible, easy to perform and safe. Further studies are needed to show the real value of this kind of procedure.

CONTEXTO: A perfuração gástrica pode ser consequência de alguns procedimentos endoscópicos, atualmente, produzida intencionalmente para acesso a alguns órgãos com o advento da cirurgia transluminal endoscópica por orifícios naturais. Esta é a razão para que os endoscopistas estudem uma maneira segura de reparar estas lesões por via endoscópica. OBJETIVO: Avaliar um novo método de fechamento das perfurações gástricas utilizadas para acesso ao NOTES. MODELO DE ESTUDO: Pesquisa em modelos animais com curto tempo de sobrevida. MÉTODO: Dez porcos da raça White Landrace, foram submetidos a perfuração gástrica de 1,8 cm, monitorizados e sob anestesia geral. A abertura gástrica foi reparada com dispositivo especial constituído por agulha em forma de T montada com fio (T-tag), inserida, por via endoscópica, nas bordas do ferimento perfurando a parede gástrica e fixando-se a ela como uma âncora. Uma câmara plástica protetora, especialmente desenvolvida, foi adaptada à ponta do endoscópio para proteção dos órgãos subjacentes. Seis T-tags foram inseridos na maioria dos casos e os pontos foram amarrados e fixados com auxílio de outro dispositivo metálico de contenção do nó denominado “tie-knot”, formando três suturas. Um teste de vazamento do tipo manobra do borracheiro era realizado ao término do procedimento. Os animais recebiam líquido no pós-operatório imediato. Foi usada profilaxia antibiótica. RESULTADOS: Não houve complicações. Um mês depois, a endoscopia de controle revelou cicatriz e alguns restos de sutura. A laparotomia, feita no mesmo tempo, revelou poucas aderências na face anterior do antro. CONCLUSÃO: O reparo endoscópico com T-tags e câmara protetora parece ser efetiva, fácil e segura. Estudos maiores e com maior tempo são necessários para confirmar estes resultados e a utilidade deste procedimento.

Fatal gastro-duodenal perforation following electrocution: A case report.

A 45 yrs old male was accidentally electrocuted, while cooking on a locally made heater in his home. He was immediately brought to the hospital in unconscious state by the family members. After first aid he was referred to a tertiary care hospital, where he was admitted about two hrs after the incident. On admission he was unconscious, abdomen was distended, with fluid in peritoneal cavity. There was tachycardia and hypotension. Bowel sounds were absent. Electrocution burn marks were present over the right hand. Arterial blood analysis showed severe metabolic acidosis. He was immediately shifted to the ICU. His condition continued to be critical with persistent metabolic acidosis despite repeated sodium bicarbonate infusion. An exploratory laprotomy was planned to rule out abdominal visceral injuries. However the patient expired six hrs after admission to the hospital before being taken to the operation theatre. Autopsy examination showed perforated anterior wall of stomach antrum and first part of duodenum.

La ingestión de cáusticos en el niño: un problema de salud pública / The caustic ingestion in children: a public health problem

La ingestión de cáusticos en la edad pediátrica es un problema grave al producir una lesión progresiva y devastadora en el esófago y el estómago. Estudio retrospectivo y descriptivo de 421 pacientes en edades comprendidas de 2 meses a 14 años quienes ingirieron cáusticos entre 1.992 y 2.008, evaluados en el Hospital Universitario de Maracaibo. El 60,09% eran pre-escolares y el 62,23% eran del sexo masculino. La sustancia tipo álcali fue ingerida en el 90,73% de los casos y los cáusticos se encontraban almacenados en su envase original en 3,8% y trasegados en el 96,2% de los casos. La ingestión fue de origen accidental en el 99,53%. Todos los pacientes manifestaron alguna sintomatología como lesiones orofaríngeas, vómitos y sialorrea. La evaluación endoscópica se realizó en el 89,31% de los casos y se evidenció lesiones en el tracto gastrointestinal en 60,63%. Los pacientes con Esofagitis Grado III y estenosis esofágica fueron incluidos en el programa de dilatación, con una buena evolución en el 35,91% de ellos. La ingestión de cáusticos constituye un problema frecuente y serio, en su mayoría de origen accidental, afecta principalmente a menores de 6 años y el álcali es el principal agente involucrado. La Endoscopia Digestiva es el estudio por excelencia para evaluar estos pacientes. Las dilataciones esofágicas son moderadamente exitosas. El mejor tratamiento es la prevención.

The caustic ingestion in the pediatric population is a serious problem because produce a progressive and devastating injury to the esophagus and stomach. Retrospective and descriptive study of 421 patients with age from 2 months to 14 years who ingested caustic between 1.992 to 2.008 evaluated at the Hospital Universitario de Maracaibo. The 60.09% were pre-school and 62.23% were male. The substance type alkali was swallowed by 90.73% of cases and the caustics were stored in its original packaging by 3.8% and decanted in 96.2% of cases. Intake was accidental source in 99.53%. All patients showed some symptoms as oropharyngeal lesions, vomiting and drooling. Endoscopy evaluation was performed by 89.31% of cases and revealed gastrointestinal tract injuries in 60.63%. Patients with grade 3 Esophagitis and esophageal stricture were admitted in the dilatation program with a good success in 35.91% of them. The caustic ingestion is a common and serious problem, mostly from accidental origin, mainly affects children under 6 years and the alkali is the principal agent involved. The Esophagoscopy is the ideal mean for evaluate these patients. The esophageal dilatations are moderately successful. The best treatment is the prevention.
