Six newborn infants with necrotizing enterocolitis (NEC) were noted to have air confined to Morison pouch as an early sign of pneumoperitoneum. Air in Morison pouch appears as a triangular lucency in the right upper quadrant. Extraluminal air in this location is easily mistaken for air within a loop of bowel if its characteristic appearance is not specifically sought. Review of the literature revealed no reported cases of NEC in which air in Morison pouch was mentioned. The authors' observation of six patients suggests that air in Morison pouch may be more common than previously recognized. Air in Morison pouch has the same significance as more obvious signs of pneumoperitoneum, and its detection is an indication for surgery.
六名患有坏死性小肠结肠炎（NEC）的新生儿被发现，局限于莫里森隐窝的气体是气腹的早期迹象。莫里森隐窝内的气体在右上腹表现为三角形透亮区。如果不特意寻找其特征性表现，该部位的腔外气体很容易被误认为肠袢内的气体。文献回顾显示，尚无提及莫里森隐窝内气体的NEC报道病例。作者对六名患者的观察表明，莫里森隐窝内的气体可能比之前认为的更为常见。莫里森隐窝内的气体与更明显的气腹体征具有相同的意义，其发现是手术的指征。
