  • 초록  

    A mature teratoma of the pancreas has rarely been reported, and postoperative superior mesenteric artery syndrome (SMAS) is extremely rare in pediatric pancreatic surgery. A 12-year-old girl underwent an enucleation of the large mature teratoma located at the pancreas uncus. Although her postoperative recovery was fair, the bile-stained gastric juice continued draining at a rate of>1.5 l per day for 2 weeks. An upper gastrointestinal series revealed an abrupt disruption with to-and-fro peristalsis at the third portion of the duodenum. Endoscopy revealed an extrinsic pulsatile compression of this third portion. The aortomesenteric angle measured 12 o on ultrasonography, which met the criteria for SMAS. The patient underwent a modified transposition procedure, ''switching jejunojejunostomy,'' on postoperative day 18. The gastrointestinal passage gradually improved, and complete oral intake was established 1 month after the first surgery. It was considered that the clinical symptoms of SMAS were caused by an anatomical deformation after the pancreatic tumor resection. Switching jejunojejunostomy was found to be an acceptable therapeutic option for this condition.
