A 9-year-old boy was admitted to our hospital due to vomiting for 4 days. He had no history of operation. A plain X-ray film demonstrated dilated intestinal gas. Ultrasonography showed a cystic mass 10 cm in diameter cranial to the cystic bladder. Drainage of the cystic mass using ultrasonography was performed because the cystic mass was considered to be the origin of obstructive ileus. Chylous fluid (200 ml) was drainaged, and ileus disappeared the following day. Mesenteric chylous cyst was suspected by CT scanning as well. Elective surgery for mesenteric chylous cyst was performed due to persistent drainage of fluid, although ielus did not occur again after the drainage procedure. Laparotomy showed a dark red mesenteric cyst of the jejunum 8 cm in diameter. Partial resection of the jejunum was performed. The size of the cyst was 7.5×6 cm in diameter, and histological study showed lymphangioma of the mesentery. This case is considered to show the usefulness of ultrasonography and ultrasonographic drainage for primary ileus in childhood.

Key words
mesenteric cylous cyst, primary ileus in the childhood, ultrasonographic drainage for mesenteric cyst
