Background/Purpose A nationwide survey was conducted to identify the clinical presentation of pediatric chronic intestinal pseudo-obstruction (CIPO) in Japan. Methods Data were collected via a questionnaire, ensuring patient anonymity, from facilities that treat pediatric gastrointestinal diseases in Japan. Results Ninety-two responses were collected from forty-seven facilities. Sixty-two patients (28 males, 34 females) met formal diagnostic criteria for CIPO. The estimated pediatric prevalence was 3.7 in 1 million individuals. More than half the children (56.5%) developed CIPO in the neonatal period. Full-thickness intestinal specimens were available for histopathology assessment in forty-five patients (72.6%). Forty-one (91.1%) had no pathological abnormalities and were considered to be idiopathic. Patients were treated according to the local protocol of each facility. Forty-one patients (66.1%) had restricted oral intake of ordinary diets, and twenty-nine (46.8%) depended on parenteral nutrition. No therapeutic intervention, including medication and surgery, successfully improved oral food intake or obstructive symptoms. Only three patients (4.8%) died from enteritis or sepsis. Conclusions In Japan, pediatric CIPO is a rare, serious, and intractable disease. The prognosis with respect to survival is good, but unsatisfactory because of the need for prolonged parenteral nutrition and associated potential for restricted quality of life.
