Midgut malrotation and incomplete rotation are common causes of neonatal intestinal obstruction. At end of 10 week of intrauterine life, cecum will be placed in subhepatic region temporarily and descends to right lower quadrant by eleventh week. Arrest of cecum in subhepatic region or undescended cecum is a rare congenital anomaly of mid gut. Usually, it remains asymptomatic and is diagnosed incidentally. If any pathology occurs in anomalous part, like appendicitis then the diagnosis and treatment will be challenging in all age groups. Variation in blood supply have also been reported with anomalies leading to iatrogenic injuries during colonoscopy and surgeries. Lack of knowledge of these rare variations may lead to delayed diagnosis of appendicitis leading to perforation and surgical emergencies. In the present case, we describe an undescended cecum and its associated variation in branching pattern of superior mesenteric artery.
中肠旋转不良和不完全旋转是新生儿肠梗阻的常见原因。在子宫内生活10周结束时,盲肠会暂时位于肝下区域,并在第11周时下降至右下腹。盲肠停滞在肝下区域或盲肠未下降是一种罕见的中肠先天性异常。通常,它没有症状,是偶然被诊断出来的。如果异常部位出现任何病变,如阑尾炎,那么在所有年龄组中诊断和治疗都将具有挑战性。也有报道称,这些异常会导致血供变化,从而在结肠镜检查和手术期间造成医源性损伤。对这些罕见变异缺乏了解可能会导致阑尾炎诊断延迟,进而导致穿孔和外科急症。在本病例中,我们描述了一个未下降的盲肠及其相关的肠系膜上动脉分支模式变异。
