RESUMEN

Introducción: el síndrome de Ogilvie es una entidad infrecuente, más aún en la edad pediátrica, caracterizada por la dilatación aguda del colon, y que suele complicar la evolución de distintas enfermedades. Dentro de sus causas más comunes está la cirugía ortopédica y/o traumatológica. Objetivo: actualizar sobre el diagnóstico y tratamiento del síndrome en las edades pediátricas. Presentación del caso: se presenta una paciente de 16 años, operada de escoliosis toraco abdominal, que a las 24 horas de operada comenzó con distensión abdominal progresiva y marcada, y se le diagnosticó de síndrome de Ogilvie. Conclusiones: la entidad, aunque infrecuente, puede presentarse en pacientes con diversas afecciones, y se debe conocer adecuadamente sobre su diagnóstico y tratamiento para lograr la recuperación del enfermo(AU)

Introduction: Ogilvie syndrome is an uncommon condition, even more so in childhood. It is characterized by acute dilation of the colon, often complicating the evolution of different diseases. Its most frequent causes include orthopedic and/or trauma surgery. Objective: update the information about the diagnosis and treatment of the syndrome in pediatric ages. Case presentation: a female 16-year-old patient who had undergone thoraco-abdominal scoliosis surgery and had developed progressive, marked abdominal distension 24 hours after the operation, was diagnosed with Ogilvie syndrome. Conclusions: infrequent as it is, the condition may present in patients with various diseases. It is necessary to have adequate knowledge about its diagnosis and treatment to achieve successful recovery in patients(AU)

RESUMEN

BACKGROUND: Diverticulosis and redundant colon are colonic conditions for which underlying pathophysiology, management and prevention are poorly understood. Historical papers suggest an inverse relationship between these two conditions. However, no further attempt has been made to validate this relationship. This study set out to assess the correlation between diverticulosis and colonic redundancy. METHODS: Redundant colon, diverticulosis and patient demographics were recorded during colonoscopy. Multivariate binary logistic regression was performed with redundant colon as the dependent variable and age, gender and diverticulosis as independent variables. Nagelkerke R 2 and a receiver operator curve were calculated to assess goodness of fit and internally validate the multivariate model. RESULTS: Redundant colon and diverticulosis were diagnosed in 31 and 113 patients, respectively. The probability of redundant colon was increased by female gender odds ratio (OR) 8.4 (95% CI 2.7-26, p = 0.00020) and increasing age OR 1.7 (95% CI 1.1-2.6, p = 0.017). Paradoxically, diverticulosis strongly reduced the probability of redundant colon with OR of 0.12 (95% CI 0.42-0.32, p = 0.000039). The Nagelkerke R 2 for the multivariate model was 0.29 and the area under the curve at ROC analysis was 0.81 (95% CI 0.73-0.90 p-value 3.1 × 10-8). CONCLUSIONS: This study found an inverse correlation between redundant colon and diverticulosis, supporting the historical suggestion that the two conditions rarely occur concurrently. The underlying principle for this relationship remains to be found. However, it may contribute to the understanding of the aetiology and pathophysiology of these colonic conditions.

RESUMEN

In spite of the large experience acquired in the last 50 years with the surgical treatment of the Chagasic megacolon, the use of colorectal video laparoscopic surgery brought some controversy in several aspects of the treatment that already had been considered as resolved. One of the basic aspects to the establishment of the colorectal video laparoscopic surgery is to maintain the same procedure of the conventional surgery, since the results obtained in this operation were considered as curative. Constipation is only a symptom of a multisymptomatic disease, and the surgical treatment of acquired megacolon must be considered as definitive in the cure of this symptom; recurrence of the constipation or dilatation after a short period of time must be considered deleterious to the patient. Based in 41 years of experience with the Duhamel procedure in the treatment of 912 patients with acquired megacolon, the authors propose to apply the same technique in the surgical laparoscopic approach of acquired megacolon, including the same colon-recto-anal anastomosis. The results obtained in 56 patients operated on by laparoscopic approach showed the same curative results, but with lower morbidity. (AU)

Apesar da vasta experiência adquirida nos últimos 50 anos com o tratamento cirúrgico do megacolo adquirido, a introdução da cirurgia laparoscópica voltou a trazer controvérsia para alguns pontos anteriormente considerados como esclarecidos. Uma das regras básicas para a introdução da videolaparoscopia no tratamento das enfermidades colorretais tem sido a de se manter a técnica original utilizada em cirurgias pela via convencional, desde que os resultados observados na mesma conduzam à cura dos sintomas ou da enfermidade causal. Em especial, no referente ao tratamento cirúrgico do megacolo adquirido a proposta de um tratamento cirúrgico deve ter em mente que diferentemente do que ocorre com a cirurgia para tratamento de outras enfermidades, benignas ou malignas, neste caso não se almeja o tratamento causal da enfermidade, mas essencialmente a cura da manifestação de um de seus sintomas. É, pois, realmente importante que se considere um tratamento que não venha a resultar em bons resultados por apenas um curto espaço de tempo, mas que possibilite ao paciente livrar-se definitivamente de um sintoma, visto que é possível que em curto espaço de tempo ele venha a necessitar tratar outra manifestação sintomatológica (cardíaca ou esofágica) da enfermidade causal. Baseados na experiência adquirida nos últimos 50 anos (912 pacientes) com a técnica de Duhamel, em que o ponto importante é a realização de uma ampla anastomose da parede anterior do cólon abaixado à parede posterior (mucosa) do reto, ao mesmo tempo em que se anastomosa a parede posterior do cólon abaixado ao canal anal, são analisados os resultados obtidos com esta mesma técnica realizada por laparoscopia. Esta mesma incisão no canal anal serve para a retirada do segmento cólico ressecado, sem necessidade de laparotomia auxiliar. Os resultados observados em 56 pacientes quanto à cura da obstipação são similares aos registrados na cirurgia convencional, porém com um menor índice de morbidade, seja intra ou pós-operatória.

RESUMEN

A case of acquired megacolon in a 62-year-old man with acute abdomen due to sigmoid volvulus is reported. The case was associated with the use of psychiatric medications. The aim in this report was to emphasize the differential diagnosis with Chagas megacolon. Anatomopathological examination did not show any evidence of denervation, ganglionitis and/or myositis, and the serological test for Chagas disease was negative.

Relata-se caso de megacólon adquirido, associado ao uso de medicamentos psiquiátricos, em homem de 62 anos, com abdome agudo por volvo de sigmóide, com o objetivo de destacar o diagnóstico diferencial de megacólon chagásico. O exame anátomo-patológico não evidenciou denervação, ganglionite e/ou miosite e a sorologia para doença de Chagas foi negativa.
