Síndrome de Ogilvie (pseudo-obstrução intestinal aguda) - Relato de caso / Ogilvie's Syndrome (Acute pseudo-intestinal obstruction) - A case report

RACIONAL: A síndrome de Ogilvie é condição clínica com sinais, sintomas e aparência radiológica de dilatação acentuada do cólon sem causa mecânica e pode complicar com rompimento da parede do cólon e sepse abdominal. O tratamento na maioria das vezes é cirúrgico. RELATO DO CASO: Paciente feminina, 49 anos, internada com queixa de dor abdominal e diarréia e apresentando-se confusa, desidratada, taquicárdica, dispnéica, temperatura de 38ºC, abdômen distendido, ausência de ruídos hidro-aéreos e toque retal com fezes pastosas. Estudo radiográfico mostrou padrão de pseudo-obstrução intestinal. A paciente evoluiu com parada de eliminação de gases e fezes e sinais de abdômen agudo infeccioso. Foi submetida à laparotomia com achado de ceco e transverso bastante dilatados e sem sinal de obstrução mecânica. Realizada colectomia subtotal com fechamento do coto distal e ileostomia terminal. CONCLUSÃO: Pensar nessa possibilidade diagnóstica e agir mais rapidamente é a única possibilidade de diminuir a morbimortalidade desses pacientes.

BACKGROUND: The Ogilvie's Syndrome is a clinical condition with signals, symptoms and radiological appearance of large bowel swell without mechanical cause. This obstruction can complicate with disruption of the bowel and consequent evolution of abdominal sepse. The treatment is typically surgical. AIM: The aim of this work is report a case of Ogilvie's Syndrome. CASE REPORT: Feminine patient, 49 years-old, interned with a history of abdominal pain and diarrhea and presenting dehydratation, tachycardia , dyspnea, mental confusion, 38ºC of temperature, distended abdomen, absence of hydro-aerial noises and rectal touch with pasty excrements. The x-ray showed a standard of pseudo-intestinal obstruction. The patient evolved with stop of elimination of farts and excrements and signals of infectious acute abdomen. The laparotomy showed cecum and transverse very swelled without signal of mechanical obstruction. The treatment was a subtotal colectomy with closing of the rectal stump and terminal ileostomy. CONCLUSION: This is rare syndrome and cases like this must be described for a faster diagnostic and adequate treatment, reducing the morbimortality of these patients.

Colonic transit study by radio-opaque markers to investigate constipation: validation of a new protocol for a population with rapid gut transit.

BACKGROUND: Constipation is a common problem, which may be due to slow transit or faecal evacuation disorders. Though the screening test of colonic transit study using radio-opaque markers given at 0, 24 and 48 hours followed by abdominal X-ray at 72 hours is a good protocol in the West, it is not suitable for Indians who have a rapid gut transit. METHODS: Nine patients with adult Hirschsprung disease, 11 with chronic intestinal pseudo-obstruction diagnosed using standard investigations and 11 healthy subjects were evaluated by colonic transit study using radio-opaque markers (SGmark), 20 each at O, 12 and 24 hours followed by an abdominal X-ray at 36 and 60 hours. The cut-off was determined by using receiver operating characteristic (ROC) curves, and sensitivity, specificity, positive and negative predictive values and diagnostic accuracy were determined. RESULTS: The total number of markers retained in the abdomen and those in the right segment at 36 hours in patients with Hirschsprung disease and chronic intestinal pseudo-obstruction was higher than that in healthy subjects though the number in the left and rectosigmoid segments were comparable. The abdominal X-ray at 60 hours, total number of markers and number in all segments were higher in patients with Hirschsprung disease and chronic intestinal pseudoobstruction than in healthy subjects. The best cut-off by ROC curves at 36 and 60 hours was 30 and 14 markers, respectively. The sensitivity, specificity, positive and negative predictive values, diagnostic accuracy and area under the ROC curve at 36 hours were 90%, 82%, 90%, 82%, 87% and 0.9, respectively; the corresponding values at 60 hours were 95%, 100%, 100%, 92%, 97% and 0.99, respectively. CONCLUSION: Using the proposed protocol, the colonic transit study is able to distinguish patients with specific motility disorders causing constipation such as Hirschsprung disease and chronic intestinal pseudo-obstruction from healthy subjects with reasonable sensitivity and specificity, and shows that an abdominal X-ray at 60 hours is better than one at 36 hours.

Neuronal intestinal dysplasia: a role for surgery?

Neuronal intestinal dysplasia (NID) is a poorly understood colonic motility disorder with characteristic histopathological findings and clinical presentation. It is often associated with Hirschsprung's disease (HD) and can constitute a cause of failure of clinical improvement after adequate resectional pull-through surgery. Other conditions associated with NID are: Chronic Intestinal Pseudo-obstruction (CIPO), anorectal malformations and Multiple Endocrine Neoplasia (MEN) II syndrome patients. To increase the diagnostic yield of NID the pathologist should be aware and use histochemistry evaluation of the rectal biopsy specimen in patients with history of constipation or unexplained bouts of diarrhea. Adequate sampling of the temporary proximal colostomy done to HD patients should be examined for NID pathological changes. Treatment has centered around the clinical picture with most cases managed medically with prokinetic agents, colonic irrigations, and bowel cathartics until improvement and normalization of histology occur. There is evidence of progressive maturation of the enteric nervous system with time. Surgery is indicated for patients with severe clinical deterioration after failed medical management

Pseudoobstrucción intestinal crónica idiopática: miopatía visceral: presentación de 4 casos / Chronic idiopathic intestinal pseudo-obstruction: visceral myopathy: report of 4 cases

La pseudo-obstrucción crónica comprende un grupo heterogéneo de desórdenes de la motilidad intestinal, que tienen una expresión clínica común: signos y síntomas de obstrucción intestinal, en ausencia de una oclusión mecánica. La causa es una falla de la propulsión intestinal. La forma crónica de pseudo-obstrución intestinal puede ser primaria o secundaria. La primaria, o pseudo-oclusión intestinal crónica idiopática (CIP de la tierra anglosajona), define a un grupo de desórdenes propulsivos, sin una enfermedad subyacente. En esta comunicación se presentan 4 pacientes con esta patología, de sexo femenino y edades comprendidas entre 4 meses y 7 años, y se realiza una revisión de la bibliografía. Los sintomas, muy similares en 3 de ellos fueron vómitos biliosos, distensión abdominal y constipación, alternando con diarrea y desnutrición grave. La 4ª paciente, diferente de las otras en edad de comienzo y evolución, presentó solo constipación importante y distensión abdominal. El diagnóstico se realizó con biopsias transmurales por mapeo en laparotomía exploratoria, a diferentes alturas del intestino y estómago. Se estudió por microscopía visceral. Ninguna presentó patología urinaria. El tratamiento médico consistió en alimentación parenteral y/o enteral. El cisapride no fué efectivo en los dos casos que se usó
