Gas within the wall of the stomach report of a case and review of the literature.

Gas within the stomach wall is a rare occurrence. A case of intramural gas is presented. When air or gas is seen within the gastric wall on x-ray, gastric emphysema, emphysematous gastritis, or pneumatosis intestinalis is diagnosed. These classifications have become vague and contradictory. Gas in the gastric wall can only come from the environment or have been produced within the wall. Gastric emphysema and emphysematous gastritis refer to these situations, respectively. These classifications are expanded and pneumatosis intestinalis is deleted as a clinical or pathological diagnosis.

Pneumatosis intestinalis and hepatic portal venous gas caused by mesenteric ischemia in an aged person.

An 82-year-old woman complaining of abdominal pain and vomiting was admitted to our emergency department. Abdominal X-ray, ultrasonography, and computed tomography showed hepatic portal venous gas, as well as pneumatosis intestinalis. We first suspected superior mesenteric arterial thrombosis. However, her physical findings, including computed tomography scanning and laboratory data, did not support the presence of bowel necrosis. The gas disappeared after 1 day. After the 12th day, she had recovered with conservative therapy, and she was discharged on the 41st day. Many reports indicate that hepatic portal venous gas is often associated with bowel necrosis, and urgent operation is recommended in such instances. In this patient, total colonoscopy on the 7th day revealed longitudinal redness, suggesting mesenteric ischemia. Thus, we speculate that this is a rare case of mesenteric ischemia without bowel necrosis associated with both pneumatosis intestinalis and hepatic portal venous gas.

Benign pneumatosis intestinalis in the setting of celiac disease.

Pneumatosis intestinalis is an uncommon finding that may indicate the presence of several alarming pathological conditions, including bowel ischemia, that require urgent surgical intervention. We report the case of a 51-year-old man with celiac disease who underwent resection of a large duodenal adenocarcinoma. Although he initially recovered rapidly from his procedure, he subsequently developed abdominal distention and leukocytosis. Abdominal imaging revealed extensive small bowel pneumatosis and pneumoperitoneum. Emergent surgical exploration revealed only bowel wall air cysts and dilated bowel but failed to demonstrate any intra-abdominal pathology. The patient recovered uneventfully and was discharged without any further complications or recurrence of symptoms. We review the current literature on the rare finding of pneumatosis intestinalis in the setting of celiac disease. In all reported cases, even when pneumatosis is accompanied by pneumoperitoneum, these alarming findings have proved to be of "benign" origin, that is with no evidence of bowel ischemia, perforation, or peritonitis. The available evidence suggests that pneumatosis in the setting of celiac disease may reflect the dissection of intraluminal gas into the inflamed bowel wall without accompanying intra-abdominal pathology. We conclude that pneumatosis intestinalis, even with accompanying pneumoperitoneum, does not uniformly mandate surgical exploration in patients with celiac disease.

Pneumatosis intestinalis and necrotizing enterocolitis associated with liver cirrhosis.

We report a 58-year-old woman with pneumatosis intestinalis and necrotizing enterocolitis associated with liver cirrhosis. She was receiving treatment for liver cirrhosis and hepatic failure when sudden severe right upper abdominal pain and fever developed. Abdominal radiograph disclosed pneumatosis intestinalis, involving the ascending colon, and small collections of free air along the right hemidiaphragm. The pneumatosis intestinalis appeared in both cystic and linear form. Autopsy revealed necrosis and multiple gas-filled mural cysts in the ascending colon. To our knowledge, this is the first case to be reported of pneumatosis intestinalis and necrotizing enterocolitis associated with liver cirrhosis.

Mild form of neonatal necrotizing enterocolitis masked by anal fissures.

In three infants with clinically mild necrotizing enterocolitis, heme-positive stools were initially attributed to anal fissures, delaying diagnosis and treatment of the enterocolitis for 4-10 days. Radiographically, pneumatosis intestinalis involved the entire colon and rectum. A causal relation may exist between necrotizing enterocolitis and anal fissure.

[Pneumatosis intestinalis mimicking free intraabdominal air: a case report].

A 47-year-old male patient had undergone endoscopic balloon dilatation six times due to pyloric stenosis however the result was not satisfying. Surgical treatment was considered. Chest X-ray revealed free sub-diaphragmatic air but there were no acute abdomen signs clinically. In abdominal computerized tomography, there were small intestinal loops anterior to the liver and there was gas collection, which can not be differentiated exactly between an extraluminal free air and the one in the bowel wall of adjacent small bowel segments. In the emergency surgery cysts filled with gas in the wall of distal ileal segments were seen. Pneumatosis intestinalis should be kept in mind in the differential diagnosis of free intraabdominal air.

Pneumatosis intestinalis.

Pneumatosis intestinalis is a usually benign condition which may affect any segment of the gastrointestinal tract from the stomach to rectum. Occasionally, however, it may be a grave prognostic sign. This article presents the spectrum of diagnostic radiographic features of the entity with emphasis on differentiation of the underlying etiologic factors. Representative examples of pneumatosis intestinalis complicating various gastrointestinal disorders are illustrated.

Pneumatosis intestinalis after lung transplant.

Pneumatosis intestinalis may be idiopathic or associated with numerous conditions. Uncommonly, it has been associated with organ transplantation. We report one case of pneumatosis intestinalis after lung transplantation in an adult patient. To our knowledge, this finding has not been reported in the radiology literature.

Conservative management of pneumatosis intestinalis.

BACKGROUND: Pneumatosis intestinalis is a rare condition characterized by subserosal and submucosal gas-filled cysts in the gastrointestinal tract; it may be associated with bowel ischemia, perforation, and a high mortality rate. As a result, many authorities advocate an aggressive surgical approach in patients with pneumatosis intestinalis. CASE: A 53-year-old female with recurrent, metastatic uterine leiomyosarcoma underwent resection of the pelvic recurrence, low anterior rectal resection with primary anastomosis, and partial hepatectomy for liver metastasis. Her postoperative course was notable for a small bowel obstruction and the finding of pneumatosis intestinalis on radiologic studies. The patient developed mild abdominal pain. She did not develop tenderness or fevers. She was managed with bowel rest, nasogastric tube decompression, total parenteral nutrition, and broad-spectrum antibiotics. The finding of pneumatosis intestinalis resolved over the ensuing 6 days. Her diet was slowly advanced, and she was discharged home in stable condition without further surgical intervention or recurrence of the obstruction or pneumatosis. Currently, her only evidence of disease is pulmonary metastases. CONCLUSIONS: In select patients, the outcome of a conservative approach to the management of pneumatosis intestinalis is not much different than surgical re-exploration for highly selected patients. The clinical condition of the patient, not solely the finding of pneumatosis intestinalis, should drive management in these cases.

Sonographic detection of intestinal pneumatosis.

Intestinal pneumatosis is an uncommon affection characterized by the presence of gas in the wall of the gastro-intestinal tract. The prognosis of this condition, observed in benign or severe diseases, is based on the outcome of the underlying affection. The diagnosis of pneumatosis intestinalis is unusually made with sonography. We report a case of pneumatosis intestinalis due to small bowel necrosis, initially suggested with sonography and further confirmed with computed tomography (CT) and pathology.

Colonic pneumatosis intestinalis in preterm infants: different to necrotising enterocolitis with a more benign course?

UNLABELLED: Necrotising enterocolitis (NEC) is the predominant immaturity-associated disease of the bowel in the preterm neonate and leads to substantial mortality and long-term morbidity. Diagnostic features of NEC include, apart from the clinical presentation, laboratory and radiological parameters. Pneumatosis intestinalis (PI) on abdominal radiographs is regarded as a criterion of definitive proof for this disease entity. The objective of this presentation is to link the topographic pattern of PI to the clinical course in cases of suspected NEC. We report two cases of radiological appearance of colonic PI indicative of NEC without associated laboratory and/or macroscopic evidence of the disease, and with minor clinical symptoms only. Data from animal studies indicate that decreased blood supply to the small bowel is associated with more extensive bowel damage as compared to impaired colonic perfusion. Therefore the topographical distribution of PI might be a more specific sign as the general presence or absence of PI. CONCLUSION: The topographical pattern of pneumatosis intestinalis may be predictive of the clinical course of inflammatory bowel disease in preterm infants.

Pneumatosis intestinalis in non-neonatal pediatric patients.

OBJECTIVES: To describe fully pneumatosis intestinalis (PI) in non-neonatal pediatric patients and to characterize those patients with higher risk of poor outcome, including need for surgery and death. METHODS: A retrospective chart review was conducted of all patients 30 days of age and older with PI in a tertiary care children's hospital during an 8-year period. Underlying medical condition, presenting signs and symptoms, radiologic grade of pneumatosis, and events that immediately preceded the onset of PI were reviewed, and their correlation with outcome was assessed. RESULTS: Thirty-seven episodes of PI occurred in 32 patients. Seventy-eight percent of patients were male, and the median age was 29 months. Major patient diagnostic groups identified with PI included healthy children (22%), patients with organ and bone marrow transplant (22%), patients with decompensated congenital heart disease (12.5%), motility disorders (12.5%), gastroschisis (9%), and short bowel syndrome (6%). The most common events that immediately preceded the onset of PI were noninfectious colitis (32%), acute enteric infection or toxin (27%), bowel ischemia (20%), and gastrointestinal dysmotility (17%). Resolution of PI with medical management occurred in 78% of episodes (good outcome). Twenty-two percent of episodes resulted in a poor outcome: patient death (8%) or surgery (14%). The presence of portal venous gas and low mean serum bicarbonate concentration were the only clinical factors that correlated significantly with poor outcome. Only 25% of patients with pneumoperitoneum required surgery. Poor outcome was seen most commonly in 2 patient diagnostic groups: transplant patients (43% of patients) and decompensated cardiac disease (50% of patients). The event that preceded PI also had an impact on outcome. PI preceded by ischemia or graft versus host disease colitis was associated with poor outcome in 50% and 75% of cases, respectively. CONCLUSIONS: PI is a radiologic sign that occurs in a variety of settings in non-neonates. PI preceded by bowel ischemia or graft versus host disease colitis has the worst prognosis, and the presence of portal venous gas and acidosis correlate with poor outcome. Not all patients with pneumoperitoneum require surgical intervention. Overall, outcome of PI in non-neonatal patients was better than that reported in neonates with necrotizing enterocolitis.pneumatosis intestinalis, necrotizing enterocolitis, non-neonatal.
