RESUMO

Introducción: el divertículo de Meckel es la anomalía congénita más frecuente del tracto gastrointestinal. Puede presentarse con hemorragia, obstrucción intestinal o diverticulitis, complicaciones que disminuyen con la edad, por lo que en el adulto el diagnóstico suele ser incidental. El tratamiento de las complicaciones es quirúrgico, mediante diverticulectomía o resección segmentaria del intestino delgado, dependiendo de sus características morfológicas. Objetivo: analizar nuestra experiencia en el manejo del divertículo de Meckel complicado en un período de 15 años. Diseño: estudio descriptivo, observacional, transversal, retrospectivo. Material y métodos: se revisaron las historias clínicas de los pacientes operados por divertículo de Meckel complicado en el Servicio de Cirugía General del Hospital San Roque durante el periodo 2007-2022. Se registraron datos demográficos, presentación clínica, diagnóstico preoperatorio, tratamiento quirúrgico, complicaciones postoperatorias y hallazgos histopatológicos. Resultados: se incluyeron 25 pacientes, 21 (84%) hombres, 3 menores de 18 años. La presentación clínica fue un síndrome de fosa iliaca derecha en el 80% de los casos, obstrucción intestinal en el 16% y hemorragia en el 4%. En solo 2 casos se realizó el diagnóstico preoperatorio, confirmado mediante tomografía computada. Se realizó diverticulectomía en el 68% de los pacientes y resección segmentaria el 32%. El abordaje fue laparotómico en el 64%, principalmente en el periodo inicial y laparoscópico en el 36%. Hubo una complicación IIIb de Clavien-Dindo en un paciente pediátrico tratado con drenaje percutáneo. En un solo paciente (4%), que se presentó con hemorragia digestiva masiva, se encontró epitelio de tipo gástrico y páncreas ectópico en el divertículo. Conclusiones: En nuestra experiencia el divertículo de Meckel complicado se presentó predominantemente en hombres. La complicación más frecuente en el adulto fue la diverticulitis. El diagnóstico preoperatorio fue infrecuente y realizado por tomografía computada. La diverticulectomía es suficiente en la mayoría de los casos. Actualmente, la laparoscopia es una herramienta segura, rentable y eficiente que permite el diagnóstico y tratamiento oportunos de esta entidad. (AU)

Introduction: Meckel's diverticulum is the most common congenital malformation of the gastrointestinal tract. It can present with bleeding, intesti-nal obstruction or diverticulitis, complications that decrease with age, so in adults the diagnosis is usually incidental. Treatment of complications is surgical, through diverticulectomy or segmental resection of the small intestine, depending on its morphological characteristics. Objective: to analyze our experience in the management of complicated Meckel's diverticulum over a period of 15 years. Design: descriptive, observational, cross-sectional, retrospective study. Materials and methods: the medical records of patients operated on for complicated Meckel's diverticulum in the General Surgery Service of the San Roque Hospital during the period 2007-2022 were reviewed. Demo-graphic data, clinical presentation, preoperative diagnosis, surgical treatment, postoperative complications, and histopathological findings were recorded. Results: twenty-five patients were included, 21 (84%) men, 3 under 18 years of age. The clinical presentation was a right iliac fossa syndrome in 80% of cases, intestinal obstruction in 16% and hemorrhage in 4%. In only 2 cases was the preoperative diagnosis made, confirmed by computed tomography. Diverticulectomy was performed in 68% of patients and segmental resection in 32%. The approach was by laparotomy in 64%, mainly in the initial period, and by laparoscopy in 36%. There was a Clavien-Dindo IIIb complication in a pediatric patient treated with percutaneous drain-age. In only one patient (4%), who presented with massive gastrointestinal bleeding, gastric-type epithelium and ectopic pancreas were found in the diverticulum. Conclusions: In our experience, complicated Meckel's diverticulum occurred predominantly in men. The most frequent complication in adults was diverticulitis. Preoperative diagnosis was infrequent and was made by computed tomography. Diverticulectomy is sufficient in most cases. Currently, laparoscopy is a safe, profitable and efficient tool that allows for the timely diagnosis and treatment of this entity. (AU)

RESUMO

ABSTRACT Introduction: Colonoscopy has shown to be useful in the diagnosis of various pathologies. By allowing the direct visualization of the mucosa, colonoscopy allows the adoption of therapeutic methods, such as the removal of polyps, dilation of stenoses, and biopsies. This method can also be applied in the detection of colorectal cancer, which currently represents an important cause of mortality in the world. Individuals considered to be at medium risk for the development of colorectal cancer should start screening at 50 years of age in order to detect early disease. Objective: To describe the main results of the exams for patients at least 50 years old who underwent colonoscopy. Method: Descriptive, case-series study of 1614 colonoscopies performed from 2014 to 2017 at a referral hospital in Salvador, Bahia. Results: The main indications for the study were intestinal bleeding (26.5%), neoplasia screening (20.7%), and abdominal pain (10.2%). The main results were diverticular disease (38.9%), polyps (38.8%), and normal examination (23.2%). Patients with indications for neoplasia screening had the presence of polyps (41.3%) as their main diagnosis. For patients with normal examination, 28.8% presented intestinal bleeding as an indication. There were 70 (4.3%) patients with a colonoscopic diagnosis of neoplasia. Conclusion: The present study, which demonstrated a majority of exams with considerable alterations, shows the usefulness of the examination, besides other advantages, as a form of diagnosis of colorectal cancer.

RESUMO Introdução: A colonoscopia mostra-se útil no diagnóstico de diversas patologias. Ao permitir a visualização direta da mucosa, possibilita a tomada de medidas terapêuticas, como a remoção de pólipos, dilatação de estenoses e realização de biopsias. Tal método pode ser empregado também no rastreio do câncer colorretal, que atualmente representa importante causa de mortalidade no mundo. Os indivíduos considerados de médio risco para o desenvolvimento do câncer colorretal, devem iniciar a triagem a partir dos 50 anos de idade, a fim de detectar precocemente a doença. Objetivo: Descrever os principais achados e indicações dos exames daqueles pacientes que realizaram colonoscopia com idade ≥ 50 anos. Método: Estudo descritivo, em série de casos, referente a 1.614 colonoscopias realizadas no período de 2014 a 2017 em hospital de referência em Salvador, BA. Resultados: As principais indicações para realização do exame foram sangramento intestinal (26,5%), rastreio de neoplasia (20,7%) e dor abdominal (10,2%). Os principais resultados encontrados foram doença diverticular (38,9%), pólipos (38,8%) e exame normal (23,2%). Os pacientes com indicação de rastreio de neoplasia tiveram como principal achado, a presença de pólipos (41,3%). Dos pacientes com exame normal; 28,8% apresentaram sangramento intestinal como indicação. Houve 70,0 (4,3%) pacientes com diagnóstico colonoscópico de neoplasia. Conclusão: O presente estudo, ao demonstrar uma maioria de exames com alterações consideráveis, evidencia a utilidade do exame, além de outras vantagens, como uma forma de diagnóstico do câncer colorretal.

RESUMO

Intestinal duplications are rare congenital anomalies that can occur anywhere along the gastrointestinal tract. Diagnosis and treatment may be difficult in some patients. We present the case of a patient who was hospitalized for rectal bleeding, with a history of recurrent abdominal pain, in whom intestinal duplication was finally diagnosed as a surgical finding. At the same time we analyze the clinical characteristics, management and treatment of intestinal duplications

Las duplicaciones intestinales son anomalías congénitas raras que pueden ocurrir en cualquier lugar a lo largo del tracto gastrointestinal. El diagnóstico y tratamiento puede ser difícil en algunos pacientes. Presentamos el caso de un paciente hospitalizado por sangrado rectal, con antecedente de dolor abdominal recurrente, en quien se diagnosticó una duplicación intestinal como hallazgo quirúrgico. A la vez analizamos las características clínicas, manejo y tratamiento

RESUMO

Objective: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract. Surgical resection is the standard treatment for localized primary GISTs. The aim of the study is to present our 5-year surgical experience, as well as the results obtained in terms of survival and disease progression. Material and Method: We conducted a descriptive, retrospective study of primary GISTs treated in our center between 2009-2013. We analyze the most relevant variables, criteria of risk of progression according Fletcher's classification from National Institutes of Health and the Miettinem's classification from the Armed Forces Institute of Pathology, as well as analysis of relapse-free survival (RFS) with Kaplan-Meier survival curves. Results: We present a series of 30 patients. Mean age 65 years (40-84 years). The most common location was the stomach (n = 14, 46.6 percent). The surgery was R0 in 23 cases of 30. The mean tumor diameter was 5.3 cm (0.5-18). 14 patients received adjuvant treatment with Imatinib. After an average follow-up of 31.2 months (6-62 months), it was found relapse in 4 patients, progression and exitus in 1, exitus in 3 and exitus in the immediate postoperative period in 1. RFS at one year was 96.7 percent, and 89.2 percent at 4 years. Mean survival time was 56.2 months (95 percent CI 51.8-60.6). Conclusion: The recommended attitude after radical surgery is follow-up. In selected patients with risk of relapse, adjuvant treatment with Imatinib delays the progression of the disease and increases the survival.

Objetivo: Los tumores del estroma gastrointestinal son las neoplasias mesenquimales más frecuentes del tubo digestivo. La resección quirúrgica es el tratamiento estándar en los GISTs primarios localizados. El objetivo del estudio es presentar nuestra experiencia quirúrgica en 5 años, así como los resultados obtenidos en cuanto supervivencia y progresión de la enfermedad. Material y Método: Serie de casos, estudio observacional descriptivo retrospectivo, que analiza los resultados obtenidos en cuanto al tratamiento quirúrgico de GIST primarios sometidos a resección quirúrgica en nuestro centro entre 2009-2013. Todas las intervenciones fueron realizadas por personal del Staff y dentro de los protocolos de las unidades de cirugía hepato-biliar y esófago-gástrica. Se analizan las variables de mayor relevancia, criterios de riesgo de progresión según la clasificación de Fletcher del National Institutes of Health y la clasificación de Miettinem del Armed Forces Institute of Pathology, así como análisis de la supervivencia libre de recaída (SLR) con curvas de Kaplan-Meier. Resultados: Presentamos una serie de 30 pacientes. Edad media de 65 años (40-84 años). La localización más frecuente fue estómago (n = 14, 46,6 por ciento). La cirugía fue R0 en 23 de los 30 pacientes. El diámetro tumoral medio fue de 5,3 cm (0,5-18, con una mediana de 4 cm. Catorce pacientes recibieron tratamiento adyuvante con Imatinib. Tras un seguimiento medio 31,2 meses (6-62 meses), se detectó recaída en 4 pacientes, progresión y exitus en 1, exitus en 3 y exitus en el postoperatorio inmediato en 1. La SLR al año fue del 96,7 por ciento, siendo del 89,2 por ciento a los 4 años. El tiempo medio de supervivencia fue de 56,2 meses (IC 95 por ciento 51,8-60,6). Conclusiones: La actitud recomendada tras una cirugía radical es el seguimiento. En pacientes seleccionados con riesgo de recaída el tratamiento adyuvante con Imatinib retrasa la progresión de la enfermedad y aumenta la supervivencia.

RESUMO

Las várices ectópicas (VE) en yeyuno son alteraciones vasculares infrecuentes, asociadas en mayor medida a la hipertensión portal (5%). Cuando se presenta sin esta asociación son aún menos frecuentes. Presentamos un caso de sangrado crónico intestinal de varios años, sin hipertensión portal proveniente de várices localizadas en yeyuno proximal, su curso clínico, los elementos de diagnóstico empleados y terapia quirúrgica.

Ectopic varices (EV) in the jejunum are a rare vascular disorder which is associated with portal hypertension (5%). It is even rarer when it occurs without associated portal hypertension. We report a case of a patient without portal hypertension who had had chronic intestinal bleeding from varices located in the proximal jejunum for several years. We report the patient’s clinical development, elements used for diagnosis and the surgical treatment.

RESUMO

Um episódio de delirium após sangramento intestinal agudo é relatado em paciente masculino com 90 anos de idade. O local de sangramento, um pólipo adenomatoso no colon direito, foi identificado por de cintilografia com eritrócitos marcados com tecnécio. O paciente recebeu hemotransfusões e haloperidol, com rápida melhora antes daressecção endoscópica do pólipo. Este relato visa a aumentar o alerta dos clínicos gerais acerca do delirium, uma condição comum entre idosos, que pode representar alta morbidade e mortalidade. A anemia deve ser incluída entre os principais fatores de risco de alterações cognitivas em idosos.

An episode of delirium after an acute intestinal bleeding is reported in a 90-year-old male. The site of bleeding was detected by technetium-labeled erythrocyte scintigraphy, and was an adenomatous polyp of the right colon. The patient received blood transfusions and haloperidol, with rapid improvement before the endoscopic resection of the polyp. This report aims is to increase the awareness of general physicians about delirium, a common condition among the oldest old that may cause high morbidity and mortality. Anemia should be included among the main riskfactors of cognitive decline in elderly.

RESUMO

A forma de avaliar e lidar com a hemorragia aguda digestiva baixa tem sido modificado com os recentes desenvolvimentos de novas técnicas e aparelhos. O nosso objetivo, por esse manuscrito, é demonstrar com simplicidade uma forma de condução dos pacientes com hemorragia digestiva baixa aguda, sobretudo para os sangramentos que parecem mais graves, principalmente quando nos faltam os recursos das avançadas tecnologias atuais. Doenças localizadas no intestino grosso respondem por » dos casos de hemorragias digestivas que são motivos para admissão hospitalar e têm como principais agentes etiológicos os divertículos, na moléstia diverticular, e as alterações vasculares, nas angiodisplasias. Na grande maioria das vezes o sangramento que pode parecer abundante cessa espontaneamente. Os distúrbios circulatórios graves não são comuns e os sinais mais frequentes são a queda do valor da hemoglobina observada na metade dos pacientes, e algumas alterações hemodinâmicas como a variação pressórica postural que pode ser vista em até 30 por cento dos casos; a síncope em 10 por cento e alguma forma de colapso circulatório, em 9 por cento. Contudo, a faixa etária em que ocorre, as condições da senilidade, as doenças eventualmente associadas e a falta de recursos materiais e humanos para lidar com esse tipo de problema são os motivos que mais causam preocupação. A abordagem clínica simples com uma história bem elaborada; o exame físico com atenção e objetividade, a inclusão do exame proctológico, a obrigatória disponibilidade de aparelho para a coloscopia e os conhecimentos básicos sobre o evento formam o conjunto necessário e, na maioria das vezes, suficiente para o correto desempenho profissional na elaboração dos cuidados que devem ser dados a esses pacientes.

The evaluation and management of the acute lower digestive hemorrhage has been modified with the recent development of new techniques and devices. The aim of this manuscript was to demonstrate with simplicity how to treat the patients with acute lower intestinal hemorrhage. Diseases of the large bowel account for the » of the cases of digestive hemorrhages on the hospital admission and have as main etiological agents the diverticula, in the diverticular disease, and small vascular malformation, in the angiodysplasias. Sometime, it can be seen as a life-threatening condition, however, most of the times, the hemorrhage stops spontaneously. The serious circulatory disturbances are not common; the most frequent signs are the decrease in hemoglobin occurring on about one half of patients and some form of circulatory disturbance as orthostatic changes in 30 percent; as syncope in 10 percent and as cardiovascular collapse in 9 percent. However, the age group, the conditions of the senility, the eventually associated diseases and the lack of material and human resources to handle with that kind of problem are the reasons for concern. The simple clinical approach with a well elaborated history; the physical examination released with attention and objectivity, the inclusion of the proctologic exam, the obligatory readiness for an endoscope for colonoscopy, the basic knowledge on the event are necessary and, in most of the times, enough for the good professional acting in the elaboration of the cares that it should be given to those patient ones.
