Abstract
An adult case of congenital segmental dilatation of the jejunum with malrotation was treated by resecting the dilated tract and performing an end-to-end anastomosis. The progress of this case was reported along with a review of the literature. 1) 9 cases of congenital segmental dilatation of the intestine with malrotation, including this case (Babut et al. 1977; Komi 1974; Kusaba et al. 1983; Rossi 1973; Swenson et al. 1959) have been reported . The relative morbidity for males and females was 2 : 7. The location in the jejunum was high in 6 cases. 2) the morbidity was the highest in infants . The etiology of this disease still remains unclear. 3) Differential diagnosis of this disease from Hiruschsprung's disease in infants and from mechanical ileus in adults is important. 4) With resection of the dilated tract and end-to-end anastomosis, g results can be obtained. This method is recognized as the best treatment. 5) The etiology of this disease is unknown. Physiological and biochemical research must be continued until the etiology is clarified.
