The annular pancreas (AP) is an uncommon congenital anomaly, characterised by a circumferential envelope in the second portion of the duodenum. In recent years, some genetic component has been found in the etiology. A newborn full-term male, weighing at 1910 g at birth, had a history of intrauterine growth restriction and diagnosis of tetralogy of Fallot, Down syndrome and congenital hypothyroidism. Duodenal membrane is suspected after persistent postprandial vomiting and abdominal distension; his abdomen was distended, hyperresonant and soft. The gastroduodenal series showed data compatible with a duodenal membrane so exploratory laparotomy was performed, finding the pancreas completely wrapping the second portion of the duodenum, so a diamond-shaped-duodenoduodenostomy anastomosis was performed. The AP should be considered, especially in male neonates with postprandial vomiting, abdominal distension, who show some other congenital anomaly, and in the abdominal X-ray, the sign of the double bubble is observed.
环状胰腺是一种罕见的先天性异常，其特征为十二指肠第二部被胰腺组织环形包绕。近年来，病因学研究发现其发病存在一定的遗传因素。一名足月男婴，出生体重1910克，有子宫内生长受限病史，诊断为法洛四联症、唐氏综合征及先天性甲状腺功能减退症。患儿出现餐后持续性呕吐及腹胀，怀疑存在十二指肠隔膜；腹部膨隆，呈鼓音，质地柔软。胃十二指肠造影显示结果符合十二指肠隔膜表现，遂行剖腹探查术，术中发现胰腺完全包绕十二指肠第二部，于是进行了菱形十二指肠十二指肠吻合术。对于餐后呕吐、腹胀且合并其他先天性异常的男性新生儿，尤其是腹部X线检查出现双泡征时，应考虑环状胰腺的可能。
