Revisión de la clasificación de Hinchey (diverticulitis) y su correlación terapéutica / Hinchey's (Diverticulitis) classification review and it's therapeutic implacations

Resumen La diverticulosis es una entidad que predomina en países occidentales. Su prevalencia aumenta con la edad, presentándose en aproximadamente el 80% de la población mayor de 85 años. Los divertículos colónicos adquiridos son herniaciones saculares de la mucosa y submucosa (pseudodivertículos) y predominan en sigma, en países occidentales; los congénitos poseen las tres capas parietales (divertículos verdaderos) y predominan en colon derecho, en países asiáticos. Aproximadamente un 10%-25% de dichos pacientes con diverticulosis presentarán a lo largo de su vida un cuadro de diverticulitis aguda, representando una de las causas más frecuentes de abdomen agudo (3,8%). Clínicamente, se expresa por dolor abdominal en fosa ilíaca izquierda (excepción en dolicosigma/divertículos congénitos derechos) y pueden presentar complicaciones como flemones, abscesos, pileflebitis, peritonitis, con consiguiente riesgo de vida. La tomografía computada (TC) permite el diagnóstico oportuno, identificación de complicaciones y planificación terapéutica. A dicho fin se establecieron diferentes clasificaciones y modificaciones, siendo la más reconocida la propuesta por Hinchey (modificada por Wasvary y col., Kaiser y col.) y otras estableciendo correlaciones con el tratamiento, como la propuesta por Sartelli y col. El objetivo del presente estudio es realizar una revisión iconográfica de esta última (Sartelli y col.) y evaluar sus implicancias terapéuticas.

Abstract Diverticular disease is an entity with high prevalence in western countries that increases with age, and affects approximately 80% of the population over 85 years of age. Acquired colonic diverticula are saccular mucosal and submucosal herniation (pseudodiverticles) and predominate in sigma, in western countries; the congenital ones possess the three parietal layers (true diverticula) and predominate in right side colon, in Asian countries. Approximately 10%-25% of patients with colonic diverticulosis, in their lifetime will present an episode of acute diverticulitis, which represents one of the most frequent causes of acute abdominal pain (3.8%). Clinically it express by abdominal pain in the left iliac fossa (exception in dolicosigma / right congenital diverticula) and may present complications such as phlegmon, abscesses, pylephlebitis, peritonitis, life threatening conditions. Computed tomography (CT) allows timely diagnosis, identification of complications and therapeutic planning. To this end, several classifications have been used, from which Hinchey's is the most renown (modified by Wasvary et al, Kaiser et al.), and other ones establish therapeutic correlation such as the one proposed by Sartelli et al. The objective of the present study is to make an iconographic review of this last one (Sartelli et al.) and to evaluate its therapeutic implications.

Diverticulitis cecal: un complejo desafío médico / Cecal diverticulitis: a complex medical challenge

Antecedentes: la diverticulitis cecal es una patología poco común en los países occidentales. Clínicamente es indistinguible de una apendicitis aguda. Objetivos: exhibir los resultados de acuerdo con diferentes abordajes terapéuticos. Material y métodos: se presentan cinco casos de diverticulitis cecal tratados en nuestra institución entre enero de 2013 y diciembre de 2015. Revisión retrospectiva de historias clínicas e imágenes. Revisión de la literatura. Resultados: fueron incluidos cinco pacientes. En cuatro hubo resolución quirúrgica y uno tuvo buena evolución con tratamiento médico. Conclusiones: si bien es poco frecuente, la diverticulitis cecal debe considerarse dentro de los diagnósticos diferenciales frente a un cuadro de dolor abdominal localizado en fosa ilíaca derecha acompañado de estudios por imágenes no categóricos de apendicitis aguda.

Background: cecal diverticulitis is a rare disease in western countries. It is clinically indistinguishable from acute appendicitis. Objetive: to show outcome with different therapeutic approaches. Material and methods: we present five cases of cecal diverticulitis treated at our institution between January 2013 and December 2015. Retrospective review of medical records and images. Review of the literature. Results: five patients were included. Four cases required surgical treatment while one patient resolved with medical treatment. Conclusions: Although it is rare, cecal diverticulitis must be considered within the differential diagnoses in the face of abdominal pain located in the right iliac fossa and non-categorical imaging of acute appendicitis.

Tomografia computada multidetector en la enfermedad diverticular del intestino delgado / Multislice computed tomography in small-bowel diverticulosis

La enfermedad diverticular del intestino delgado constituye una entidad de rara presentación, que suele confundirse con otras patologías más comunes cuando se complica. Los falsos divertículos son de origen primario o secundario, y asientan mayoritariamente en el duodeno. El divertículo verdadero más frecuente es el de Meckel. Las complicaciones aparecen en menos del 15% de los casos. Entre ellas, se destacan, por frecuencia, la perforación y/o inflamación, la obstrucción, el sangrado, y/o la diarrea crónica. El objetivo de este trabajo es mostrar el rol de la tomografía computada multidetector en el diagnóstico y manejo de la enfermedad diverticular del intestino delgado, exponiendo casos de la práctica diaria con correlato quirúrgico de pacientes evaluados en nuestra institución.

Small bowel diverticula is an uncommon and underdiagnosed pathology. False diverticula may be primary or secondary in origin and are frequently located in the duodenum. Meckel's diverticula is the most common true diverticula. Less than 15% of cases suffer complications, of which the following are, with decreasing frequency: inflammation and perforation, obstruction, bleeding, or chronic diarrhoea. In order to contribute to the best diagnosis and management of small-bowel diverticulosis, cases are presented that were initially evaluated with multislice computed tomography and confirmed surgically in our institution.

Diverticulitis aguda de intestino delgado en un paciente con enfermedad de Crohn: Report of one case / Acute small bowel diverticulitis in a patient with crohn’s disease

Diverticular disease of the small intestine is rare, especially when it is located in the jejunum. It is generally asymptomatic, but in some patients it may have complications such as acute diverticulitis with peritonitis, gastrointestinal bleeding or obstruction. In such cases, the recommended treatment is surgery. We report a 77-year-old patient with ileal Crohn’s disease with a long-standing inflammatory phenotype, who developed acute diverticulitis of the jejunum presenting a severe septic shock and secondary multiple-organ failure. It resolved with medical treatment and prolonged antibiotic therapy.

Cecal diverticulitis or appendicitis: when should I suspect? A case report

The objective of this article was to report a case of cecal diverticulitis and point out the differential diagnosis of acute appendicitis. The clinical manifestations of these pathological conditions are similar, and the accurate diagnosis of cecal diverticulitis before the surgery is difficult. Therefore, most diagnoses are made during the surgery. Moreover, cecal diverticulum is uncommon in western countries, but it is prevalent in Asian people and their descendants. We report a case of a 55-year-old female patient, whose imaging exams (ultrasonography and computed tomography) and blood tests were not enough to diagnose the affection, requiring laparotomy and pathological exams for the final diagnosis. Some studies suggesting the best practice in case of diverticulum of the cecum were revised, as the diagnosis usually occurs during the surgery. (AU)

O objetivo deste trabalho foi relatar um caso de diverticulite no ceco e chamar a atenção para o diagnóstico diferencial com apendicite aguda. As manifestações clínicas das duas afecções são semelhantes, dificultando o diagnóstico exato de diverticulite cecal, além de ser incomum, em nosso meio, o aparecimento de divertículo em cólon direito, sendo essa entidade mais comum em asiáticos e em seus descendentes. Relata-se atendimento a uma paciente de 55 anos, cujos exames de imagem (ultrassonografia e tomografia computadorizada) e de sangue não foram suficientes para o diagnóstico. Houve necessidade de realizar-se laparotomia exploradora e exames anatomopatológicos para a confirmação. Também foram revisados alguns trabalhos que sugerem qual a melhor conduta a ser tomada quando se encontra divertículo cecal no perioperatório, já que, na maioria das vezes, o diagnóstico é feito neste momento.

Ultrasound examination of gastrointestinal tract diseases

With recent technical advances, increasing use of sonography in the initial evaluation of patients with abdominal disease may allow the detection of unexpected tumor within the abdominal cavity. Easiness of sonographic detection of bowel pathology, purposely or unexpectedly, warrants the inclusion of bowel loops during ultrasound examination when a patient complains of symptoms indicating diseases of the bowel. In patients complaining of acute abdominal symptoms or nonspecific gastrointestinal symptoms and showing signs such as abdominal pain, diarrhea, hematochezia, change of bowel habit, or bowel obstruction, sonography may reveal the primary causes and may play a definitive role in making a diagnosis. On ultrasonography, abnormal lesions may appear as fungating mass with eccentrically located bowel lumen (pseudokidney sign) or symmetrical or asymmetrical, encircling thickening of the colonic wall (target sign). In patients with mass or wall thickening detected on ultrasonography, additional work-up such as barium study, CT or endoscopy would be occasionally necessary for making a specific diagnosis.
