Neumatosis quística intestinal complicada con vólvulo intestinal / Pneumatosis cystoides intestinalis complicated with intestinal volvulus

La neumatosis quística intestinal es una condición infrecuente caracterizada por la presencia de quistes con gas en la subserosa o submucosa del tracto gastrointestinal. Su patogénesis es incierta y se han propuesto varios mecanismos patogénicos para explicar su origen. Se presenta el caso de un paciente de sexo masculino de 46 años de edad con diagnóstico previo de neumatosis quística intestinal, que consultó por dolor abdominal, vómitos y fiebre (39 °C). Ingreso con signos de irritación peritoneal. La radiografía simple de abdomen reportó distensión intestinal y niveles hidroaéreos. Se realizó laparotomía exploratoria que reveló vólvulo de intestino delgado con estrangulamiento de algunas asas intestinales. El diagnóstico anatomopatológico fue neumatosis quística intestinal complicada con Infarto transmural por vólvulo intestinal. El paciente evoluciono satisfactoriamente

Pneumatosis cystoides intestinalis is a rare condition in which multiple gas-filled cysts are found within the wall of the gastrointestinal tract either in the subserosa or submucosa. Its pathogenesis is uncertain and several pathogenic mechanisms have been proposed to explain its origin. The case of a male patient of 46 years with previous diagnosis of pneumatosis cystic intestinalis, who consulted for abdominal pain, vomiting and fever (39 °C) is presented. By the time of admission ther were signs of peritoneal irritation. The X-ray abdominal reported distension and intestinal hydro-air levels. Exploratory laparotomy was performed and revealed small bowel volvulus with strangulation of some intestinal segment. Histological diagnosis was pneumatosis cystic intestinalis complicated with Infarction trans-mural by intestinal volvulus. The patient evolved satisfactorily.

A Case of Necrotizing Colitis Presenting with Hepatic Portal Venous Gas and Pneumatosis Intestinalis / 대한소화기학회지

Hepatic portal venous gas is a very rare radiologic sign which is characterized by gas accumulation in the portal venous circulation. Pneumatosis intestinalis is also very rare and is characterized by multiple air cysts in the serosal or submucosal layers of the gastrointestinal tract walls. These two findings are caused by various pathological conditions and can develop individually or simultaneously. The latter is clinically more significant because it is frequently related to bowel ischemia or necrosis, and represents a poor prognosis. However, prognosis is more influenced by the severity of underlying disease rather than hepatic portal venous gas or pneumatosis intestinalis itself. If bowel ischemia or necrosis is the primary cause, emergency operation is very important to improve patient's prognosis. Herein, we report a case of necrotizing colitis presenting as hepatic portal venous gas and pneumatosis intestinalis which was successfully managed by early surgery.

Pneumatosis quística intestinalis: presentación de un caso y revisión de la literatura / [Pneumatosis cystoides intestinalis: a case report and review of the literature].

Pneumatosis cystoides intestinalis features the presence of subserum or submucous cysts with gas in the intestinal wall. Its prevalence is 0.03

, although it has increased in the past decades due to a greater use of colonoscopy in everyday medical practice. Though there are several theories about its origin and many associated diseases were reported, its pathogenesis still remains uncertain. It is generally diagnosed as a finding in an imaging test. The treatment depends on the severity of the associated disease and symptoms. We report the case of a 59-year-old woman, heavy smoker, with no other clinical conditions who took a medical consultation due to abdominal bloating. She underwent a screening colonoscopy which detected the existence of cysts on the colonic wall. Afterwards, a computed tomography was performed and showed apical lung bullae, gas in a colonic wall segment, and ascitis associated to a big anexial tumor. She underwent a cytoreductive surgery, confirming the presence of advanced ovary neoplasm. The endoscopic biopsy confirmed the diagnosis of penumatosis cystoides intestinalis. We report these case because it is a rare entity which requires uncommon management and treatment guidelines.

A Case of Pneumatosis Cystoids Intestinalis with Polymyositis / 대한소화기학회지

Pneumatosis cystoides intestinalis (PCI), characterized by presence of intramural gas cyst in the intestinal wall is associated with various medical condition. Polymyosistis, however, is rarely associated with PCI. Few cases are reported in the world, and none has not been reported previously in Korea. A 67-year-old woman with polymyositis developed mild abdominal pain and abdominal distension during treatment with steroid and azathioprine. Radiographic findings including CT scan showed intraperitoneal free gas and intramural air, compatible with PCI. The patient's symptom and clinical findings improved after the treatment with antibiotics and high-dose oxygen therapy.

Neumatosis intestinal y gas portal, asociada a trombosis portal: comunicación de un caso y revisión de literatura / Pneumatosis intestinalis and portal hepatic gas in asociation with portal thrombosis

Se presenta un caso clínico de una asociación infrecuente de Neumatosis intestinal con gas en vena porta y trombosis portal. Mujer de 37 años quien presenta cuadro de distensión y dolor abdominal de cuadro días de evolución. A su ingreso se encuentra afebril con presión arterial de 120/70. A su examen físico destaca sólo sensibilidad abdominal. Se realiza tomografía computada de abdomen y pelvis que muestra presencia de imágenes quísticas con gas en pared de colon ascendente, aire en sistema venoso portal y trombosis en rama de la vena porta. Se inicia tratamiento con antibióticos y oxígeno.La paciente evoluciona en forma favorable siendo dada de alta 11 días después de su ingreso. Varios estudios han mostrado que la Neumatosis intestinal aislada o con gas en la vena porta puede estar asociada a diferentes condiciones clínicas, sin embargo, la asociación de Neumatosis intestinal, gas y trombosis portal es un hallazgo infrecuente.

We report a rare condition of Pneumatosis intestinalis with hepatic portal venous gas associated to portal thrombosis. A 37 years old female presented with abdominal pain andbloating from four days before admission. Blood pressure was 120/70 and body temperature normal. Physical examination revealed only abdominal tenderness. CT scan showed intestinalgas-filled cysts, air in portal venous system and thrombosis at portal vein branches. Treatment with oxygen and antibiotic therapy was followed by a clinical improvement and patient was discharged after 11 days. Several studies have reported Pneumatosis intestinalis alone and with Hepatic portal venous gas in different pathological conditions. HoweverPneumatosis intestinalis with hepatic portal venous gas associated with portal thrombosis is a unusual condition.

Micropneumatosis coexistent with Helicobacter pylori and its improvement.

Micropneumatosis intestinalis is the occurrence of gas-filled circular voids with diameter of 20-200 microns, not lined with epithelium. We report a 39-year-old man with superficial gastritis and Helicobacter pylori infection who also had gastric, duodenal and colonic micropneumatosis. Endoscopic biopsy after treatment for H. pylori gastritis showed no micropneumatosis in gastric, duodenal or colonic mucosal sections. We suggest that H. pylori may be one of the causative factors for micropneumatosis.
