Pneumatosis cystoides intestinalis

A brief outline of the aetiology and pathogenesis of pneumatosis cystoides intestinalis is given followed by a review of four cases which have occurred in the Glasgow area recently. The radiological appearances of the condition are considered in detail.     

Pneumatosis cystoides intestinalis associated with pyloric stenosis

Pneumatosis cystoides intestinalis is a rare condition characterized by the presence of gas-filled cysts in the bowel wall. A case is reported which was associated with peptic ulcer and in which there was involvement of the ileum and pre-pyloric region of the stomach. Stomach involvement is a rare occurrence. Chronic pneumoperitoneum was also present. The mechanism of its occurrence is discussed.     

Pneumatosis cystoides intestinalis associated with ascites and pyloric stenosis secondary to a chronic duodenal ulcer: case report

A thirty eight year old female with a long standing history of a chronic duodenal ulcer presented at the Nyeri Provincial General Hospital with vomiting, abdominal pain and abdominal distension. Oesophago-gastro-duodenoscopy revealed a tight pyloric stenosis while abdominal ultrasonography showed ascites. At laparatomy, she was coincidentally found to have pneumatosis cystoides intestinalis (PCI). The recent literature is reviewed and this case of PCI associated with ascites and pyloric stenosis secondary to a chronic duodenal ulcer is reported.     

Pneumatosis cystoides intestinalis. Treatment with oxygen via close-fitting mask.

Four patients with pneumatosis cystoides intestinalis were recently treated with oxygen via a close-fitting mask. They responded initially to this therapy, with cessation of all symptoms and, after seven days of treatment, with return of proctoscopic and barium-contrast roentgenographic findings in the colon to normal. However, the disease recurred in one of the four patients after six months. There is a potential hazard of toxic effects from oxygen, and this may be detected by frequent measurement of pulmonary vital capacity. Our experience corroborates the efficacy of oxygen therapy in the treatment of this disorder but we question its long-term effectiveness in all cases.     

Intestinal emphysema (Pneumatosis cystoides intestinalis) in a gnotobiotic pig.

A gnotobiotic pig monocontaminated with an enteropathogenic Escherichia coli was subsequently hyperimmunized to produce a monotypic antiserum. At necropsy, multiple, air filled cysts were found in the wall of the large intestine. The etiology of this condition is still conjectural. However, select strains of E. coli may cause or contribute to intestinal emphysema in swine.     

Primary pneumotosis cystoides intestinalis

We describe an unusual case of pneumatosis cystoides intestinalis (PCI) in a patient with chronic pulmonary disease. A 79-year-old woman was hospitalized due to abdominal fullness and bowel habit change. Colonoscopy revealed numerous round cystic lesions in the sigmoid colon, which bled easily on contact. Due to persistent local peritonitis, a left hemicolectomy with primary anastomosis was performed. The patient has done well in the 12 months following surgery.     

肠囊样积气症临床病理学观察

目的 整理1例肠囊样积气症及文献中12例的诊治结果,探讨肠囊样积气症的临床病理特征.方法 收集本院诊治肠囊样积气症1例的临床及病理资料,查阅文献,收集临床及病理资料完整的病例12例,对患者的性别、年龄等临床资料及大体所见、病理诊断等相关情况进行分析比较.结果 临床以胃肠道症状为主,男性略多于女性,发病年龄宽泛,主要发病部位为结肠,活检镜下可见囊腔,多核巨细胞、炎细胞浸润等.结论 肠囊样积气症是一种罕见的消化系统疾病,其临床表现易与其他消化道疾病相混淆,需在疾病早期进行肠镜检查及病理活检后明确诊断进而进行规范化治疗.
