RESUMO

BACKGROUND: Intestinal duplications are rare congenital developmental anomalies with an incidence of 0.005-0.025% of births. They are usually identified before 2 years of age and commonly affect the foregut or mid-/hindgut. However, it is very uncommon for these anomalies, to arise in the colon or present during adulthood. CASE PRESENTATION: Herein, we present a case of a 28-year-old woman with a long-standing history of constipation, tenesmus, and rectal prolapse. Colonoscopy results were normal. An abdominal computed tomography (CT) revealed a diffusely mildly dilated redundant colon, which was prominently stool-filled. The gastrografin enema showed ahaustral mucosal appearance of the sigmoid and descending colon with findings suggestive of tricompartmental pelvic floor prolapse, moderate-size anterior rectocele, and grade 2 sigmoidocele. A laparoscopic exploration was performed, revealing a tubular duplicated colon at the sigmoid level. A sigmoid resection rectopexy was performed. Pathologic examination supported the diagnosis. At 1-month follow-up, the patient was doing well without constipation or rectal prolapse. CONCLUSIONS: Tubular colonic duplications are very rare in adults but should be considered in the differential diagnosis of chronic constipation refractory to medical therapy. Due to the non-specific manifestations of this entity, it is rather challenging to make an accurate diagnosis pre-operatively. Surgery remains the mainstay of treatment. Some reports suggest that carcinomas are more prone to develop in colonic/rectal duplications than in other GI tract duplications.

RESUMO

Introducción: El divertículo colónico gigante es una presentación rara de la enfermedad diverticular del colon descrita por primera vez en la literatura francesa en 1946; se define cuando su diámetro es mayor a 4cm. Objetivo: Adicionar a la literatura dos casos diagnosticados en la Fundación Oftalmológica de Santander, Colombia debido al bajo número de casos reportados en la actualidad; además, mencionar los principales datos encontrados en la literatura en cuanto a la epidemiología, la presentación clínica, los diagnósticos diferenciales, las herramientas diagnósticas más importantes a tener en cuenta y la diferencia de los esquemas de tratamiento. Presentación de los casos: Se presentan dos casos de pacientes con clínica de dolor abdominal para los cuales se solicitaron estudios imagenológicos que permitieron realizar un adecuado diagnóstico de divertículo colónico gigante; el primero fue manejado de manera conservadora con antibiótico-terapia y el segundo de forma quirúrgica con resección de colon transverso con anastomosis primaria. Conclusiones: El divertículo colónico gigante es una entidad poco frecuente y por tanto escasamente descrita en la literatura asociada en su mayoría con la diverticulosis. Se presenta con una clínica muy diversa, sugestiva de múltiples patologías abdominales que deben ser descartadas para poder realizar un adecuado diagnóstico por medio de técnicas de imagen como la radiografía, el colon por enema y la tomografía axial computarizada que representan las principales herramientas diagnósticas de esta entidad. El tratamiento de elección es la intervención quirúrgica, sin embargo, en contextos determinados como pacientes ancianos, asintomáticos y con alto riesgo quirúrgico puede manejarse de manera conservadora. Su importancia a pesar de la baja prevalencia radica en la necesidad del diagnóstico oportuno para evitar una alta tasa de complicaciones.

Introduction: The giant colonic diverticulum is a rare presentation of the diverticular disease of the colon described for the first time in French literature in 1946 and it is defined when its diameter is greater than 4cm. Objective: To add to the literature two more cases diagnosed in the Ophthalmological Foundation of Santander, Colombia due to the low number of cases reported today; in addition, to mention the main data found in the literature in terms of epidemiology, clinical presentation, differential diagnoses, the most important diagnostic tools to consider and the difference of treatment schemes for it. Presentation of the cases: Two cases of patients with abdominal pain clinic for whom imaging studies were requested that allowed an adequate diagnosis of giant colonic diverticulum are presented. The first one was managed conservatively with antibiotic therapy and the second one was surgically treated with a transverse colon resection with primary anastomosis. Conclusions: The giant colonic diverticulum is a rare entity and therefore poorly described in the literature associated mostly with diverticulosis. It is presented with a very diverse clinic, suggestive of multiple abdominal pathologies that must be discarded in order to perform an adequate diagnosis by means of imaging techniques such as x-rays, colon by enema and computerized axial tomography scan which represent the main diagnostic tools for this entity. The treatment of choice is surgery; however, in determined contexts such as with elderly patients who are asymptomatic and with a high surgical risk can be managed conservatively. Its importance despite its low prevalence lies in the need for timely diagnosis to avoid a high rate of complications.

RESUMO

The yellow nail syndrome is scarcely described and is characterized by dystrophic nails, pulmonary disturbances and lymphedema of extremities. A case of this syndrome is reported in an 89-year-old Brazilian woman with well-controlled diabetes mellitus and arterial hypertension. Additionally to the typical syndrome, the patient also presented pincer nails and yellow-brownish chromonychia. She was admitted because of acute abdominal symptoms associated with sigmoid diverticulitis and an adjacent abscess. The imaging studies revealed pulmonary and pleural changes, in addition to pericardial effusion. Incidentally, the features of Phrygian cap gallbladder anomaly were found. Neither diverticular disease nor gallbladder disorders have been related to yellow nail syndrome. In the present case study, the synchronism between some of these conditions could be casual; but diverticular disease, cholelithiasis, and diaphragmatic hernia are associated in the Saint's triad.

El síndrome de las uñas amarillas está poco descrito y se caracteriza por uñas distróficas, trastornos pulmonares y linfedema de las extremidades. Se presenta un caso de este síndrome en una mujer brasileña de 89 años de edad con diabetes mellitus bien controlada e hipertensión arterial. Adicionalmente al síndrome típico, la paciente presentó uñas en pinza y cromoniquia amarillo-marrón. La paciente fue admitida debido a síntomas abdominales agudos asociados con diverticulitis del sigmoide y un absceso adyacente. Los estudios de imágenes revelaron cambios pulmonares y pleurales, además de un derrame pericárdico. Incidentalmente, se encontraron anomalías características de vesícula biliar en gorro frigio. Ni la enfermedad diverticular ni los trastornos de la vesícula biliar se han relacionado con el síndrome de las uñas amarillas. En el presente estudio de caso, el sincronismo entre algunas de estas condiciones podría ser casual, pero la enfermedad diverticular, colelitiasis, y hernia hiatal se asocian a esta tríada.

RESUMO

INTRODUÇÃO: As fístulas enterovesicais (FEV) são comunicações patológicas entre a bexiga e as alças intestinais pélvicas. Trata-se de uma rara complicação decorrente de doenças inflamatórias e neoplásicas da pelve, além de casos resultantes de iatrogenia, e associa-se a altos índices de morbimortalidade. RELATO DO CASO: Trata-se de um paciente de 61 anos com um quadro de dor e distensão abdominal, vômitos, parada de eliminação de fezes e flatos. APP: Hipertenso, diabético, com antecedentes de disfunção vesical e infecções do trato urinário de repetição (ITUr) nos últimos três anos. Por meio da realização de ressonância magnética de abdômen e pelve, diagnosticou-se FEV associada à doença diverticular (DDC) do sigmoide. A conduta estabelecida consistiu em colectomia parcial com rebaixamento de colo e cistectomia parcial com colocação cirúrgica de cateter duplo jota à esquerda. DISCUSSÃO: Embora consista de afecção primária do trato digestivo, normalmente o paciente com DDC associada a FEV procura atendimento médico em decorrência de queixas do trato urinário. Nesse caso, a demora no diagnóstico fez com que a queixa principal fosse do trato digestivo e com antecedentes de queixas urinárias. CONCLUSÃO: Apesar de pouco frequente, a ocorrência de ITUr associada à DDC deve ser sempre considerada no diagnóstico diferencial das ITUr pela alta morbimortalidade.

INTRODUCTION: Enterovesical fistula are pathological connections between the bladder and pelvic intestinal segments. It consists of a rare complication of neoplastic and inflammatory pelvic disorders, in addition to iatrogenic or traumatic injuries, and correlates with both high morbidity and mortality indexes. CASE REPORT: Male patient, 61 years old, admitted at the hospital clinics featuring abdominal pain and distension, vomiting and fecal retention. Patient's pathological precedents include high blood pressure, diabetes mellitus, vesical dysfunction and recurrent urinary tract infection on the past three years. Magnetic resonance imaging of abdomen and pelvis revealed enterovesical fistula in association with colon diverticular disease of the sigmoid. Management of choice consisted of partial colectomy with bowel lowering and partial cystectomy with surgical double-J stent insertion. DISCUSSION: Although consisting of a gastrointestinal primary affection, patients with enterovesical fistula usually search for medical help charging urinary tract features. In this particular case, our patient was admitted with gastrointestinal symptoms, reasoned by diagnostic delay, as the patient had already attended at multiple centers with urinary symptoms. CONCLUSION: Despite being an unusual affection, recurrent urinary tract infection associated with colon diverticular disease must always be considered at differential diagnosis of recurrent urinary tract infection as it concurs with high morbidity and mortality.

RESUMO

El divertículo colónico invertido es un hallazgo endoscópico inusual, algunos autores lo señalan dentro de las manifestaciones clínicas como sangramiento digestivo bajo, no se reportan otras complicaciones, a no ser que existan errores en el diagnóstico que conlleven a la toma de biopsia del mismo, así como la resección endoscópica.Caso clínico: paciente masculino, de 70 años de edad, que acudió a consulta por presentar cuadro doloroso abdominal en el lado izquierdo desde hace varios meses, con períodos de mejoría y recaídas. Como síntomas acompañantes presentó, fiebre de causa desconocida que mejoraba con antipiréticos, así como constipación de más de cinco años para lo cual tomaba laxantes con cierta frecuencia, presentó deposiciones con estrías de sangre en más de una ocasión. Al examen físico se constató dolor a la palpación profunda en el lado izquierdo y mucosas ligeramente hipocoloreadas

Reverse colonic diverticulum is an unusual endoscopic finding, some authors point it out within the clinical manifestations, lower gastrointestinal bleeding, other complications are not reported unless there are errors in diagnosis leading to a biopsy, as well as endoscopic resection.Case report: a 70 years old, male patient came to the consultation by presenting a picture of abdominal pain on the left side from several months ago, with periods of improvement and relapses. As accompanying symptoms developed fever of unknown cause which improved with antipyretics, as well as constipation for over five years, taking laxatives regularly. In addition, he presented stools with blood striae more than once. In the physical examination was found pain in left side to the deep palpation and slightly hypocolored mucus

RESUMO

Introduction: Diverticular disease of the appendix is an infrequent finding in the study of surgical specimens from patients operated on for clinically suspected acute appendicitis. Our aim was to determine the prevalence of diverticular disease of the appendix in patients who underwent appendectomies based on the clinical diagnosis of acute appendicitis. Material and Method: Design: Cross-sectional study. Inclusion criteria: Patients who underwent appendectomies based on a clinical diagnosis of acute appendicitis. Studyperiod: january 2000 to december 2008. Sampling: Non-probabilistic sampling of consecutive cases. Methodology: A review was conducted of the clinical records and surgical specimens from patients who underwent appendectomies based on a clinical diagnosis of acute appendicitis. Results: Within the study period, 11.472 appendectomies were performed based on a clinical diagnosis of acute appendicitis. Ninety-four patients presented diverticular disease of the appendix (0.8 percent). The median age was 40 years and 62.8 percent were male. The disease appeared as: appendicular diverticulitis (45.7 percent), appendicular diverticulosis with acute appendicitis (28.7 percent), appendicular diverticulitis with acute appendicitis (17.0 percent), appendicular diverticulosis (5.3 percent), and appendicular pseudodiverticulosis with acute appendicitis (3.2 percent). Operative morbidity was 12.7 percent. One patient presented an adenocarcinoma of the appendix associated with diverticular disease. Conclusion: The prevalence of diverticular disease of the appendix is low in our population and the characteristics are different to reported by other authors.

Introducción: La enfermedad diverticular del apéndice cecal es un hallazgo infrecuente en apendicectomizados por sospecha clínica de apendicitis aguda.
