2.3 Laboratory data and Imaging study
laboratory results showed a leukocytosis (white blood cell (WBC):15600/MCL), neutrophilia (absolute count of polymorphonuclear calls: 12948/MCL), C-reactive protein level (4.4 mg/dL), and ketonuria(acetone:4+) (WBC:4-6/hpf, epithelial cell: 0-1/hpf, few bacteria) in urine analysis.
Ultrasonography (US) confirmed an ileal–ileal invagination as a ”doughnut” sign with obstructive findings, free abdominopelvic fluid, and no vascular flow in invaginated Loup in doppler investigations.
