Congenital intestinal atresia requires emergency surgery soon after birth. Lymphangioma, a benign tumor, is caused by an anomalous lymphatic system. We report a case of congenital intestinal atresia associated with a mesenteric cystic lymphangioma in a low birth weight neonate.
At 21 weeks of pregnancy, ultrasonography revealed a cystic lesion in the fetal abdominal cavity. At 31 weeks, magnetic resonance imaging showed dilatation of the small intestine. This low birth weight (1752 g) male infant was born by vaginal delivery at 32 weeks 3 days' gestation. Laparotomy on day 2 of life revealed jejunal atresia and a mesenteric cyst. The cyst was removed and intestinal anastomosis was performed. Histologically, the cyst proved to be a mesenteric lymphangioma.
The most popular theories regarding the mechanism of congenital intestinal atresia include reperfusion injury and intestinal tract blood flow disturbance. In this fetus, intestinal torsion had occurred around the mesenteric cystic lymphangioma, which apparently disturbed the mesenteric blood flow and caused intestinal atresia.
There have been few reports of the combination of a mesenteric cystic lymphangioma and congenital intestinal atresia. This case supports the theory that small bowel atresia and stenosis are caused by accidental blood flow disturbance.
先天性肠闭锁出生后需尽快进行急诊手术。淋巴管瘤是一种良性肿瘤,由异常的淋巴系统引起。我们报告一例低体重新生儿先天性肠闭锁合并肠系膜囊性淋巴管瘤的病例。
妊娠21周时,超声检查发现胎儿腹腔有一囊性病变。31周时,磁共振成像显示小肠扩张。这名低体重(1752克)男婴在孕32周3天时经阴道分娩出生。出生后第2天进行剖腹手术,发现空肠闭锁和一个肠系膜囊肿。切除囊肿并进行了肠吻合术。组织学检查证实该囊肿为肠系膜淋巴管瘤。
关于先天性肠闭锁机制的最流行理论包括再灌注损伤和肠道血流紊乱。在这个胎儿中,围绕肠系膜囊性淋巴管瘤发生了肠扭转,这显然扰乱了肠系膜血流并导致肠闭锁。
肠系膜囊性淋巴管瘤与先天性肠闭锁合并的报道很少。该病例支持小肠闭锁和狭窄是由意外的血流紊乱引起的这一理论。
