Novedades en la evaluación y tratamiento de la obstrucción intestinal alta

La obstrucción intestinal mecánica es un problema quirúrgico significativo en términos de prevalencia, morbimortalidad y costos económicos asociados. En los últimos años se han realizado avances en: detectar mecanismos fisiopatológicos del desarrollo de adherencias, optimizar el diagnóstico de pacientes aptos para manejo conservador, valorar la utilidad intraoperatoria de herramientas que definan la necesidad de resección intestinal y hallar terapias preventivas. El objetivo de esta revisión narrativa es sintetizar la evidencia científica actualizada, publicada referente al diagnóstico y tratamiento de una obstrucción intestinal alta mecánica.

Mechanical small bowel obstruction is a significant surgical problem in terms of prevalence, morbimortality, and associated economic costs. In recent years, advances have been made in: detection of physio pathological mechanisms of adhesion genesis, improvement in diagnosis of patients suitable for conservative treatment, assessment the efficacy of intraoperative tools that define the need for intestinal resection, and development of preventive therapies. The objective of this narrative review is to synthesize the updated scientific evidence published, regarding the diagnosis and treatment of mechanical small bowel obstruction.

Necrosis intestinal, una complicación infrecuente de la nutrición enteral por yeyunostomía / Mesenteric necrosis, a rare complication of feeding jejunostomy

RESUMEN La nutrición enteral es parte importante del soporte vital avanzado en el paciente crítico, y ha demostrado ser más fisiológica, económica y con resultados superiores a la nutrición parenteral. La yeyunostomía para alimentación enteral está indicada cuando no es posible la alimentación por vía oral y está contraindicada la utilización de una sonda nasogástrica o nasoyeyunal de alimentación. Es una vía de alimentación con escasa morbilidad, aunque no está exenta de complicaciones, y algunas de ellas pueden ser graves. Comunicamos un caso de necrosis intestinal vinculado a la alimentación enteral por yeyunostomía en un paciente sometido a una gastrectomía oncológica.

ABSTRACT Enteral nutrition is an important component of advanced life support in the critically ill patient, and has demonstrated to be more physiologic, cheaper and with better results than parenteral nutrition. Jejunostomy for enteral nutrition is indicated when the oral route is impossible and the use of a nasogastric or nasojejunal feeding tube is contraindicated. Although the rate of complications associated with enteral nutrition through jejunostomy is low, they may occur and be serious. We report a case of bowel necrosis associated with a jejunostomy performed for enteral nutrition in a patient who underwent oncologic gastrectomy.

Cuando la ileítis de Crohn no es solo ileítis / When Crohn's ileitis is not just ileitis

RESUMEN En una minoría de pacientes con ileítis de Crohn (EC) de larga evolución, la recrudescencia de los síntomas puede representar una neoplasia ileal, con una clínica indistinguible de la enfermedad basal y por ende poco sospechada. Frecuentemente la patología tumoral se diagnostica en la pieza quirúrgica, tras una intervención por hemorragia u obstrucción intestinal. El objetivo de este trabajo es destacar la importancia de un diagnóstico diferencial ante una ileítis terminal en un paciente con EC con mala respuesta a tratamiento médico.

ABSTRACT In a minority of patients with long-standing Crohn's ileitis, the recrudescence of symptoms may represent a neoplasm involving the ileum that is clinically indistinguishable from the baseline disease and therefore poorly suspected. Tumors are often diagnosed in the surgical specimen, after an intervention due to bleeding or bowel obstruction. The aim of this study is to emphasize the importance of the differential diagnoses of terminal ileitis in a patient with CD with poor response to medical treatment.

Adenocarcinoma de yeyuno proximal: a propósito de un caso / Proximal jejunal adenocarcinoma, a case report

Resumen El adenocarcinoma de yeyuno es el tumor primario del intestino delgado más infrecuente y raro, y representa el 3 % de todos los cánceres gastrointestinales, con una incidencia anual estimada de 0,3 a 2 casos por cada 100 000 personas. En Estados Unidos y España representa el 0,4 % de los cánceres gastrointestinales y el 0,2 % de las muertes asociadas a malignidad, con síntomas inespecíficos como anemia de etiología inexplicable, dolor abdominal y pérdida de peso; la mayoría de ellos son diagnosticados en etapas avanzadas de la enfermedad. A continuación, se presenta el caso de una paciente femenina de 46 años con síntomas inespecíficos, pérdida de peso, dolor abdominal y vómito, cuya tomografía abdominal computarizada evidenció el sitio y extensión de la lesión neoplásica, mientras que la cápsula endoscopia y enteroscopia mostró una lesión neoplásica en el yeyuno proximal. La histopatología reportó un adenocarcinoma de yeyuno moderadamente diferenciado que presentó resultados favorables gracias a la resección quirúrgica curativa, lo cual mejoró el pronóstico de vida a 5 años y tuvo un seguimiento favorable hasta la actualidad.

Abstract Jejunal adenocarcinoma is the rarest primary small bowel tumor and represents 3% of all gastrointestinal cancers, with an estimated annual incidence of 0.3 to 2 cases per 100 000 people. This disease accounts for 0.4% of gastrointestinal cancers and 0.2% of deaths associated with malignancy in the United States and Spain, with nonspecific symptoms, such as anemia of unexplained etiology, abdominal pain, and weight loss; most cases are diagnosed in advanced stages of the disease. The following is the case of a 46-year-old female with non-specific symptoms, weight loss, abdominal pain and vomiting. A computerized tomography scan of the abdomen allowed determining the site and extension of the tumor, while a capsule endoscopy and an enteroscopy showed a neoplastic lesion in the proximal jejunum. A histopathology analysis reported moderately differentiated adenocarcinoma of jejunum with favorable results after a curative surgical resection that improved the prognosis of life at 5 years and with favorable follow-up until to date.

Caracterización de lesiones duodenales y su sobrevida / Characterization of duodenal lesions and their survival

Resumen Introducción: Las lesiones duodenales son infrecuentes. Objetivo: Caracterizar a los pacientes con lesiones duodenales observados entre enero de 2008 y diciembre de 2013 en el Servicio de Salud Metropolitano Sur, en Santiago de Chile. Materiales y Método: Se obtuvieron los datos de los registros del Hospital Barros Luco Trudeau y Hospital El Pino. Los pacientes incluidos fueron los observados entre enero de 2008 y diciembre de 2013. Se analizaron edad, género, características clínicas, localización, métodos diagnósticos, hallazgos anatomopatológicos y tratamiento. El 24 de abril de 2019 se obtuvo la fecha de fallecimiento de todos los pacientes del Registro Civil. El análisis estadístico se realizó con el software STATA 15.1. Resultados: Se encontraron 157 pacientes con lesiones duodenales, 65 presentaron adenocarcinoma duodenal y 71 pacientes pólipos duodenales, 25 de ellos fueron adenomas. Análisis univariado de sobrevida evidenció que los pacientes con pólipos asociado a carcinoma y los adenocarcinomas duodenales, presentaron una sobrevida inferior (p = 0,013, HR 6,584 y p < 0,001, HR 7,604, respectivamente). En los pacientes con adenocarcinoma duodenal, aquellos que se sometieron a una cirugía con intención curativa, y aquellos que recibieron quimioterapia tuvieron una sobrevida global mejor que aquellos que no recibieron terapia (p < 0,001, HR 0,351 y p = 0,001, HR 0,276, respectivamente. Discusión: La incidencia estimada del adenocarcinoma duodenal en nuestra población es de 1,1 por cada 100.000 habitantes, la que es más alta que otras publicadas. Proponemos estudio endoscópico en poblaciones de riesgo y tratamiento con intención curativa para los pacientes con adenocarcinoma duodenal sin metástasis a distancia.

Introduction: Duodenal lesions are infrequent. Aim: To characterize patients with duodenal lesions observed between January 2008 and December 2013 at the Southern Metropolitan Health Service, in Santiago, Chile. Materials and Method: Data were obtained from the Barros Luco Trudeau Hospital and El Pino Hospital records. The patients included were those observed between January 2008 and December 2013. Age, gender, clinical characteristics, location, diagnostic methods, anatomopathological findings and treatment were analyzed. On April 24th 2019 was obtained the date of death of all patients at the National Civil Registry. The statistical analysis was performed with the software STATA 15.1. Results: 157 patients with duodenal lesions were found, 65 presented duodenal adenocarcinoma and 71 patients had duodenal polyps, 25 of them were adenomas. Univariate analysis of survival showed that patients with polyps associated with carcinoma and duodenal adenocarcinomas had a lower survival rate (p = 0.013, HR 6.584 y p < 0.001, HR 7.604, respectively). In patients with duodenal adenocarcinoma, those who underwent surgery with curative intent, and those who receive chemotherapy had a better overall survival than those who did not received therapy (p < 0.001, HR 0.351 y p = 0.001, HR 0.276, respectively). Discussion: We propose endoscopic study in at-risk populations and treatment with curative intent for patients with duodenal adenocarcinoma without distant metastases. The estimated incidence of duodenal adenocarcinoma in our population is 1.1 per 100,000 inhabitants and seem to be higher than other published.

Evisceración vaginal post histerectomía abdominal. Presentación de un caso / Vaginal eviscerationafter abdominal hysterectomy. Filing a case / Evisceração vaginal após histerectomia abdominal. Arquivar um caso

RESUMEN Introducción: la evisceración vaginal después de una cirugía pélvica es una emergencia quirúrgica extremadamente rara. La dehiscencia laparotómica consiste en la desunión y separación precoz de los bordes de una herida quirúrgica suturada, con exteriorización o sin ella del contenido de la cavidad abdominal. Presentación de caso: el caso que aquí se reporta es el de unamujer de 36 años con antecedentes de hipertensión arterial. Intervenida hacia 3 meses de histerectomía abdominal por fibromiomas, sin prolapso uterino. Acude al cuerpo de guardia del hospital por dolor abdominal, sensación de ocupación vaginal y estreñimiento. Niega distensión abdominal y síntomas respiratorios. Ya en el cuerpo de guardia refiere deseos de defecar y al pujar ocurre una protrusión de intestino delgado de más o menos 3 cm, irreductible a través de orificio vaginal. Se realizó laparatomía, revisión por vía vaginal, reducción de las asas intestino delgado y ampliación del orificio por donde se produjo la evisceración. Discusión: se localizaron los bordes del peritoneo parietal, se sutura la cúpula vaginal con puntos continuos y se colocó una malla en el fondo de la pelvis recubierta por peritoneo. Se utilizaron los datos provenientes de la historia clínica hospitalaria. Exámenes complementarios, la entrevista y el examen físico de la paciente, a pesar las probables complicaciones no hubo pérdida de tiempo y la operación fue un éxito. Conclusiones: la evolución fue satisfactoria, gracias a la labor del personal médico que estuvo a cargo del caso.

ABSTRACT Introduction: vaginal evisceration after pelvic surgery is an extremely rare surgical emergency. Laparotomic dehiscence consists of disunity and early separation of the edges of a sutured surgical wound, with or without externalization of the contents of the abdominal cavity. Case presentation: the case reported here is that of a 36-year-old woman with a history of high blood pressure. She underwent 3 months of abdominal hysterectomy for fibromyomas, without uterine prolapse. She comes to the hospital guard corps for abdominal pain, a feeling of vaginal occupation and constipation. He denies abdominal bloating and respiratory symptoms. Already in the body of guard it refers desires to defecate and when pushing a protrusion of small intestine of more or less 3 cm occurs, irreducible through the vaginal opening. Laparatomy, vaginal revision, reduction of the small intestine loops and enlargement of the hole through which evisceration occurred were performed. Discussion: the edges of the parietal peritoneum were located, the vaginal dome was sutured with continuous stitches, and a mesh was placed at the bottom of the pelvis covered by peritoneum. The data from the hospital medical history were used. Complementary examinations, the interview and the physical examination of the patient, despite the probable complications, there was no loss of time and the operation was successful. Conclusions: the evolution was satisfactory, thanks to the work of the medical personnel who were in charge of the case.

RESUMO Introdução: a evisceração vaginal após cirurgia pélvica é uma emergência cirúrgica extremamente rara.

Tasa de conversión y morbilidad en el abordaje laparoscópico en pacientes seleccionados con obstrucción intestinal adherencial / Morbidity and Conversion Rate in Laparoscopy Approach in Selected Patients with Adhesive Intestinal Obstruction

Introducción: El síndrome adherencial es la causa más frecuente de obstrucción de intestino delgado. La laparotomía es el abordaje estándar. El avance de la cirugía mínimamente invasiva hace posible la resolución de cuadros obstructivos por laparoscopia. Objetivo: Analizar el abordaje laparoscópico de la obstrucción intestinal y compararlo con la vía abierta. Método: Análisis retrospectivo de los pacientes tratados de obstrucción intestinal aguda mediante laparoscopia en nuestro hospital desde 2012 hasta 2016. Se utilizó como referencia un grupo de pacientes tratados desde 2002 hasta 2005, cuando sólo se usaba el abordaje abierto. Se analizaron datos demográficos, riesgo quirúrgico, comorbilidades, métodos diagnósticos y complicaciones (Clavien). Resultados: De los 134 pacientes intervenidos de obstrucción intestinal aguda, se inició un abordaje laparoscópico en 47 (35 pr ciento). Por esta vía sólo se completaron 32 pacientes (68 por ciento). La tasa de conversión fue del 32 por ciento, estos pacientes fueron eliminados del estudio. En el grupo de referencia se analizaron al azar 32 pacientes. Ambos grupos son comparables. El grupo tratado con abordaje laparoscópico tuvo un 9 por ciento de complicaciones y un 3 por ciento de reintervenciones, con una sola lesión inadvertida. El grupo laparoscópico tuvo un 12,5 por ciento de reintervenciones, todas por evisceración, pero tuvo una lógica mayor tasa de resecciones intestinales. No hubo mortalidad hospitalaria. Conclusión: Los resultados en los pacientes en que se ha completado la cirugía por laparoscopia se comparan favorablemente con los del abordaje abierto en un grupo histórico homogéneo de referencia, y sin el riesgo añadido de evisceración(AU)

Introduction: Adherence syndrome is the most frequent cause of small bowel obstruction. Laparotomy is the standard approach. The progress of minimally invasive surgery makes it possible to resolve obstructive frames by laparoscopy. Objective: To analyze the laparoscopic approach for intestinal obstruction and compare it with the open pathway. Method: Retrospective analysis of patients treated for acute intestinal obstruction by laparoscopy in our hospital, from 2012 to 2016. A group of patients treated from 2002 to 2005 were used as reference, when only the open approach was used. We analyzed demographic data, surgical risk, comorbidities, diagnostic methods and complications (Clavien). Results: Within the 134 patients operated for acute intestinal obstruction, a laparoscopic approach was started in 47 (35 percent). Only 32 patients (68 percent) were completed in this way. The conversion rate was 32 percent, these patients were eliminated from the study. In the reference group, 32 patients were randomly analyzed. Both groups are comparable. The group treated with laparoscopic approach had 9 por ciento complications and 3 percent reoperations, with a single unexpected lesion. The laparoscopic group had 12.5 of reintervention, all due to evisceration, but had a higher rate of intestinal resections. There was no hospital mortality. Conclusion: In patients who have completed laparoscopic surgery, the results are compared favorably with those of the open approach in a homogeneous historical reference group, and without the added risk of evisceration(AU)

Malrotación intestinal: a propósito de un caso / Intestinal malrotation: a case report

Existen múltiples patologías del abdomen que pueden ser diagnosticadas por parte del especialista en Diagnóstico por Imágenes; entre ellas, la malrotación intestinal es un hallazgo generalmente incidental. El médico imagenólogo debe ser capaz de reconocer los signos de la malrotación intestinal, al tratarse de una entidad patológica con complicaciones graves, como el vólvulo de intestinal. Para el diagnóstico, es clave su sospecha, así como las variantes de la normalidad que pueden conducir a un diagnóstico erróneo.

The doctor specialist imaging must be able to recognize the signs of intestinal malrotation is a pathological entity, with serious complications, such as intestinal volvulus. For the diagnosis, it is the key to your suspicion, as well as the variants that can lead to a false diagnosis.

Linfangioma mesentérico quístico de intestino delgado simulando tumoración ovárica / Mesenteric cystic lymphangioma of small bowel mimicking ovarian tumor

Resumen El linfangioma quístico, caracterizado por proliferación de los espacios linfáticos, es una lesión infrecuente en pacientes adultos. Menos del 1% de todos los linfangiomas corresponden a linfangiomas del intestino delgado. La presentación clínica es diversa, variando desde un quiste abdominal asintomático, diagnosticado de forma incidental, a un cuadro de abdomen agudo. Se presenta un caso de linfangioma mesentérico quístico del intestino delgado en una mujer de 30 años y quien consultó por dolor abdominal y vómitos. La ecografía y la tomografía computada abdominal mostraron un quiste con múltiples septos en el cuadrante inferior derecho simulando un tumor de ovario. En la laparotomía se encontró un tumor quístico, lobulado y marrón, procedente del mesenterio del intestino delgado. A la paciente se le realizó resección de la tumoración y del intestino delgado adyacente con reconstrucción del tránsito intestinal. La evaluación histológica confirmó el diagnóstico de linfangioma mesentérico quístico.

Abstract Cystic lymphangioma, characterized by proliferation of lymphatic spaces, is an infrequent lesion in adult patients. Less than 1% of all lymphangiomas correspond to small-bowel lymphangiomas. Clinical presentation can be diverse ranging from incidental abdominal cysts to an acute abdomen. We report a case of small bowel mesenteric cystic lymphangioma in a 30 years-old woman who presented with abdominal pain and vomiting. The abdominal ultrasound and computed tomography scan showed a cystic multiseptated mass at the right lower quadrant mimicking an ovarian tumor. Laparotomy found a lobulated, brown, cystic tumor from the small bowel mesentery. The patient underwent resection of the tumor and the adjacent small intestine with reconstruction of the intestinal transit. The histological study confirmed diagnosis of mesenteric cystic lymphangioma.

Primer trasplante de intestino delgado en Costa Rica

El primer trasplante de intestino exitoso realizado en humanos se llevó a cabo en 1988, en Alemania, por el Dr. Deltz. Sin embargo, no es hasta diciembre de 2013, cuando en Costa Rica, en el hospital "Dr. Rafael Ángel Calderón Guardia", se efectúa el primer trasplante humano de intestino delgado del país y la región. Se reporta el caso de un masculino de 18 años que tuvo isquemia intestinal masiva, secundaria a herida por arma blanca en abdomen, con compromiso vascular. El injerto provino de donador cadavérico. La inmunosupresión se basó en baxiliximab, tacrolimus, prednisona y micofenolato mofetil. Se reintervino en 7 ocasiones por complicaciones quirúrgicas; desarrolló lesión renal asociada a tacrolimus, mielotoxicidad y trombosis venosa profunda de venas ilíacas. Se mantuvo por 29 días con nutrición parenteral total; se avanzó a vía oral normal a los 40 días del trasplante. Se evaluó el injerto mediante ileoscopias y toma de biopsias. Finalmente, después de 68 días, fallece debido a rechazo agudo severo del injerto.

The first successful small bowel transplant was performed in1988 in Germany by Dr Deltz and co workers. However in Costa Rica it was until december 2013 that was done the first small bowel transplant at the Dr. Rafael Angel Calderon Guardia Hospital. It also became the first small bowel transplant in Central America. This report the case of a young male that had a stabb wound in his abdomen and developed a massive mesenteric ischemia with vascular compromise. The allograft was procured from a cadaveric donor. The recipient received immunosuppression with baxiliximab, tacrolimus, prednisone y micophenolate mofetil. Due to surgical complications the patient underwent 7 more surgeries, he developed tacrolimus induced renal dysfunction, myelotoxicity and iliac deep venous thrombosis. He remained under total parenteral nutrition for 29 days post transplant, then oral intake was introduced and by the day 40 he was a full oral nutrition. Serial endoscopies and biopsies were performed during the weeks after transplantation. Finally at day 68 the patient dies due to acute severe rejection.

Neurofibroma del mesenterio en un paciente sin enfermedad de Von Recklinghausen / Mesenteric neurofibroma seen in a patient without Von Recklinghausen´disease

Los neurofibromas son tumores benignos del sistema nervioso que pueden ser solitarios o múltiples: la neurofibromatosis o enfermedad de Von Recklinghausen. Estos tumores en general son de consistencia blanda, frecuentes a nivel de partes blandas, su localización en el aparato digestivo es infrecuente y no son encapsulados. El objetivo del presente trabajo fue presentar el caso de una paciente con neurofibroma mesentérico sin enfermedad de Von Recklinghausen. Se presenta el caso de una paciente de 41 años que fue ingresada por dolor abdominal y una tumoración palpable en la región entre flanco e hipocondrio izquierdo. En los estudios imaginológicos realizados se informó como quiste del mesenterio, lo que fue confirmado en el acto quirúrgico. Se realizó exéresis de la tumoración informada por Anatomía Patológica como neurofibroma secundariamente enquistado benigno. El neurofibroma mesentérico es una tumoración que puede verse en pacientes sin enfermedad de Von Recklinghausen.

Neurofibromas are benign tumors of the nervous system that can be solitary or multiple, the neurofibromatosis or Recklinghausen's disease. In general, these tumors are soft, non-encapsulated, more frequent in soft parts of the body and infrequent in the digestive system. The objective of the present paper was to present a female patient with mesenteric neurofibroma and without Von Recklinghausen disease. Here is a 41 years-old female patient who was admitted to the hospital because she suffered abdominal pain and a palpable tumor at the region between left flank and hypochondrium. The imaging studies revealed a mesenteric cyst, which was confirmed in surgery. The tumor was classified as a benign cyst neurofibroma by pathological anatomy and finally removed. The mesenteric neurofibroma is a tumor that can be found in patients without Von Recklinghausen disease.

Conclusion: The surgical option obtained success on removing and definitely treating the small bowel tumor.

Linfoma T intestinal monomórfico CD56+. Primer caso informado en Colombia y revisión de la literatura / Monomorphic Intestinal T-Cell Lymphoma. First reported case in Colombia and review of the literature

Se informa el caso de una mujer de 80 años con hallazgo incidental de masa abdominal en mesogastrio. Se le realiza resección de intestino delgado por sospecha de absceso con síndrome adherencial. El estudio patológico de la pieza quirúrgica demostró compromiso por linfoma no Hodgkin T monomórfico CD56+. Los linfomas T del tubo digestivo son inusuales; corresponden al 5% de las neoplasias linfoides de esta localización. El linfoma intestinal T monomórfico CD56+ corresponde a 10-20% de los linfomas T intestinales. Se presenta en regiones donde la enfermedad celiaca es infrecuente y no se asocia a enteropatía. Su curso es agresivo y habitualmente se manifiesta como una emergencia quirúrgica por obstrucción o perforación intestinal.

80 year old woman with incidental finding of abdominal mass in midgut, in which small bowel resection is performed for suspected abscess associated to surgical adhesions. Pathological examination of the surgical specimen showed a monomorphic CD56+ T cell lymphoma. T-cell lymphomas of the digestive tract are rare, accounting for 5% of all lymphoid neoplasms in this location. Monomorphic CD56+ intestinal T cell lymphoma corresponds to 10 - 20% of T cell intestinal lymphomas. This tumor occurs in regions where celiac disease is rare and it is not associated with enteropathy. Its course is aggressive and usually manifests as a surgical emergency by intestinal obstruction or perforation.

Tratamiento laparoscópico de la obstrucción intestinal por bridas / Laparoscopic treatment of adhesive small bowel obstruction

Background: Treatment options for adhesive small bowel obstruction (ASBO) involve conservative and surgical management, traditionally through open adhesiolysis. Laparoscopic approach has been performed in recent years; however, limited data exist on its safety and results vary considerably. Our aim is to report our experience of laparoscopic treatment for ASBO. Methods: Retrospective study including patients admitted with the diagnosis of adhesive small bowel obstruction and that were submitted to laparoscopic exploration, between June 2003 and April 2013. We analyzed demographic, surgical variables and outcomes in terms of conversion rate, operative time, re-feeding time and length of stay. Non-parametric tests were used for statistical analysis. Results: Series of 38 patients submitted to laparoscopic exploration, mean age: 51 +/- 16 years, 47 percent male. 53 percent had prior intra-abdominal surgeries. Laparoscopic resolution of bowel obstruction was possible in 31 patients (82 percent), with 7 conversions to open surgery. Median operative time was 60 (25-180) minutes, median re-feeding time was 24 (24-192) hours and median length of stay was 4 (2-52) days. Two patients required re-intervention during their hospital stay, one due to persistent bowel obstruction and one due to ischemic colitis. There were no other complications or mortality. Conclusions: Laparoscopy in adhesive small bowel obstruction was a feasible approach in this series, with good results when laparoscopic resolution is achieved. Patients with no prior surgeries seem to be good candidates for this approach.

Introducción: El tratamiento de la Obstrucción Intestinal por Bridas (OIB) incluye alternativas conservadoras y quirúrgicas, esta última tradicionalmente a través de cirugía abierta. El abordaje laparoscópico ha sido incorporado recientemente, sin embargo, existe información limitada sobre su seguridad y sus resultados varían considerablemente. Nuestro objetivo es presentar la experiencia de nuestro centro en el tratamiento laparoscópico de la OIB. Material y Métodos: Estudio retrospectivo incluyendo pacientes con el diagnóstico de OIB que fueron sometidos a cirugía laparoscópica en nuestro centro, entre junio de 2003 y abril de 2013. Análisis de variables demográficas, quirúrgicas y resultados obtenidos en términos de tasa de conversión, tiempo operatorio, tiempo de realimentación y estadía hospitalaria. Análisis estadístico con pruebas no paramétricas. Resultados: Serie de 38 pacientes, edad promedio: 51 +/- 16 años, 47 por ciento sexo masculino. 53 por ciento con antecedente de cirugía abdominal previa. Resolución completa por laparoscopía fue posible en 31 pacientes (82 por ciento), con 7 conversiones a cirugía abierta. La mediana de tiempo operatorio fue de 60 m (25-180), la mediana de tiempo a la realimentación fue de 24 h (24-192) y la mediana de estadía hospitalaria de 4 (2-52) días. Dos pacientes requirieron reoperaciones durante su hospitalización; uno debido a obstrucción intestinal persistente y otro debido a colitis isquémica. No se presentaron otras complicaciones ni mortalidad en esta serie. Conclusiones: El abordaje laparoscópico en OIB es factible de realizar en pacientes seleccionados, logrando buenos resultados en caso de resolución completa por laparoscopía. Pacientes sin cirugías abdominales previas son buenos candidatos para un abordaje laparoscópico inicial.

Adenocarcinoma del intestino delgado asociado al síndrome de Lynch / Adenocarcinoma of the small intestine associated with Lynch syndrome

El síndrome de Lynch (SL) es una enfermedad autosómica dominante causada por una mutación en los genes de reparación del ADN que predispone al cáncer colorrectal (CCR) y a otros tumores extracolónicos. Entre estos predominan los del endometrio, estómago, tracto urinario alto y ovario. La incidencia de los tumores de intestino delgado (TID) si bien es baja (0,4-2,9%), supera en más de 25 veces a la de la población general. El objetivo de este trabajo es presentar un caso de carcinoma del duodeno en un paciente masculino de 47 años con criterios de Amsterdam II, y discutir las características de los TID en el SL.

Lynch Syndrome (LS) is an autosomal dominant condition caused by mutations in the mismatch repair genes that predispose to colorectal cancer (CRC) and other extracolonic tumors. Among these, endometrial, gastric, ovarian, and urinary tract tumors are the commonest. The incidence of small bowel tumors (SBT), although low (0.4-2.9%), exceeds in more than 25 times that of the general population. The purpose of this paper is to communicate a case of carcinoma of the duodenum in a 47 years old male with Amsterdam II criteria, and discuss the characteristics of SBT in LS.

Transplante de intestino delgado / Small bowel transplantation

INTRODUÇÃO: O transplante de intestino delgado, em razão de sua complexidade, apresentou evolução mais lenta que os demais órgãos sólidos. Diversos avanços permitiram sua aplicação clínica. OBJETIVO: Revisão da evolução do transplante de intestino delgado e seu estado atual. MÉTODO: levantamento bibliográfico nas bases de dados MEDLINE e ScIELO. Os termos usados como descritores foram: intestinal failure, intestinal transplant, small bowel transplant, multivisceral transplant. Foram analisados dados sobre evolução histórica, centros, indicações, tipos de enxertos, seleção e captação de órgãos, manejo pós-operatório, complicações e resultados. CONCLUSÃO: Apesar de desenvolvimento mais lento, o transplante intestinal é hoje a terapia para pacientes portadores de falência intestinal irreversível que apresentam complicações da nutrição parenteral. Envolve algumas modalidades: intestino delgado isolado, fígado-intestino, multivisceral e multivisceral modificado. Atualmente a sobrevida é semelhante aos demais órgãos sólidos. A maioria dos pacientes fica livre da nutrição parenteral.

BACKGROUND: Small bowel transplantation evolution, because of its complexity, was slower than other solid organs. Several advances have enabled its clinical application. AIM: To review intestinal transplantation evolution and its current status. METHOD: Search in MEDLINE and ScIELO literature. The terms used as descriptors were: intestinal failure, intestinal transplantation, small bowel transplantation, multivisceral transplantation. Were analyzed data on historical evolution, centers experience, indications, types of grafts, selection and organ procurement, postoperative management, complications and results. CONCLUSION: Despite a slower evolution, intestinal transplantation is currently the standard therapy for patients with intestinal failure and life-threatening parenteral nutrition complications. It involves some modalities: small bowel transplantation, liver-intestinal transplantation, multivisceral transplantation and modified multivisceral transplantation. Currently, survival rate is similar to other solid organs. Most of the patients become free of parenteral nutrition.

Um ensaio randomizado duplo-cego e controlado por placebo com probióticos em casos de supercrescimento bacteriano no intestino delgado em crianças tratadas com omeprazol / A double-blind placebo-controlled randomized trial on probiotics in small bowel bacterial overgrowth in children treated with omeprazole

OBJETIVO: Avaliar a incidência de SBID em crianças tratadas com omeprazol e testar se os probióticos influenciam essa incidência. MÉTODOS: Um ensaio duplo-cego controlado por placebo foi realizado em 70 crianças tratadas oralmente, durante 4 semanas, com 20 mg de omeprazol por dia. Desses, 36 indivíduos receberam diária e simultaneamente Lactobacillus rhamnosus R0011 (1,9 x 10(9) cfu) e Lactobacillus acidophillus R0052 (0,1 x 10(9) cfu) (grupo probiótico), enquanto 34 receberam placebo (grupo placebo). O diagnóstico de SBID teve como base o desenvolvimento de sintomas sugestivos em combinação com um teste respiratório com glicose positivo. RESULTADOS: Após um mês de tratamento com IBP, 30% (21/70) apresentaram um teste respiratório positivo sugerindo SBID; desses, 62% foram sintomáticos. Cinco crianças desenvolveram sintomas parecidos com os de SBID, mas apresentaram um teste respiratório negativo; 44 (63%) não apresentavam sintomas e tiveram teste respiratório negativo. Não houve diferença na incidência de testes respiratórios positivos no grupo probiótico em comparação ao grupo placebo (33% em comparação a 26,5%; p: 0,13). CONCLUSÕES: Como houve sintomas sugestivos de SBID em 26% das crianças tratadas com IBP e o teste respiratório com glicose deu resultados anormais em 72% delas, esse efeito colateral deve ser levado em consideração com mais frequência. O probiótico testado não reduziu o risco de desenvolver SBID.

OBJECTIVE:To evaluate the incidence of small bowel bacterial overgrowth (SBBO) in children treated with omeprazole, and to test whether probiotics influence the incidence. METHODS: A double-blinded, placebo-controlled trial was performed in 70 children treated orally during four weeks with 20 mg omeprazole per day. Lactobacillus rhamnosus R0011 (1.9 x 10(9) cfu) and Lactobacillus acidophillus R0052 (0.1 x 10(9) cfu) were simultaneously given daily to 36 subjects (probiotic group), while 34 subjects received placebo (placebo group). The diagnosis of SBBO was based on the development of suggestive symptoms, in combination with a positive glucose breath test. RESULTS: After one month of proton pump inhibitor (PPI) treatment, 30% (21/70) had a positive breath test suggesting SBBO; of these 62% were symptomatic. Five children developed SBBO-like symptoms, but had a negative breath test; and 44 (63%) were symptom free and had a negative breath test. There was no difference in the incidence of positive breath tests in the probiotic versus the placebo group (33% vs 26.5%; p = 0.13). CONCLUSIONS: Since symptoms suggesting SBBO developed in 26% of PPI-treated children, and since the glucose breath test was abnormal in 72% of these, this side-effect should be more frequently considered. The probiotic tested did not decrease the risk to develop SBBO.
