The relationship between pneumatosis cystoides intestinalis (PCI) and occupation was studied in 66 patients reported in Japan during a 5-yr-period from 1979-1983. Information concerning their occupation was obtained from 37 (56.1%) patients; 16 patients had secondary PCI and 21 had primary PCI. No particular characteristics were noted in the occupations of secondary PCI patients. Primary PCI, occurring more frequently in females (15/21), affected predominantly the large intestine (20/21), locally involving the sigmoid colon in the majority (14) of the patients. Most patients with primary PCI (16/21) were factory workers, of whom 15 (71.4%) were engaged in degreasing of manufacturing products with trichloroethylene. The high percentage of trichloroethylene workers among the patients with primary PCI suggests that occupational exposure to this agent constitutes an etiological factor in the development of this disease.
对1979年至1983年这5年间日本报告的66例肠气囊肿病（PCI）患者与职业的关系进行了研究。从37例（56.1%）患者那里获得了有关其职业的信息；16例患者为继发性PCI，21例为原发性PCI。继发性PCI患者的职业未发现特殊特征。原发性PCI在女性中更常见（15/21），主要累及大肠（20/21），大多数患者（14例）局部累及乙状结肠。大多数原发性PCI患者（16/21）是工厂工人，其中15例（71.4%）从事用三氯乙烯对制造产品进行脱脂工作。原发性PCI患者中三氯乙烯工人的比例很高，这表明职业性接触该制剂是这种疾病发生的一个病因。
