Clinical analysis of 35 cases of upper gastrointestinal heterotopic pancreas / 重庆医学

Objective To explore the cinical ,endoscopic and endoscopic ultrasonography (EUS) manifestations of upper gastro-intestinal heterotopic pancreas(HP) and the treatment value .Methods The clinical data in 35 cases of upper gastrointestinal HP confirmed by pathology in our hospital were retrospectively analyzed for summarizing its clinical symptoms ,endoscopic and EUS manifestations and the treatment effect under endoscopy .Results Among all the 35 cases ,the cinlincal symptoms were in 30 cases , upper abdominal pain in 18 cases ,abdominal distension in 5 cases ,belching in 4 cases ,melena in 3 cases ,the lesion was located in gastric antrum in 23 cases ,in gastric body in 3 cases ,in gastric fundus in 3 cases ,in gastric angle in 2 cases ,in the junction of gastric antrum and corpus ventriculi in 2 cases ,in durodenal bulb in 2 cases ,most HP were represented by protuberant lesions under endos-copy ,the diameter of the lesions ranged 0 .5-2 .0 cm .20 cases were centrally umbilicated hollow with ducts opening on the top of the protuberant lesion .Under EUS ,the lesions involved submucosa in 28 cases ,mucosa in 2 cases ,muscularis mucosae in 4 cases , and muscularis propria in 1 case .4 cases appeared as the midium echo ,24 cases as hypoecho and 7 cases as mixed echo ,among them ,the tubular structure echo within the lesions were found in 10 cases .20 cases were treated by endoscopic mucosal resection (EMR) ,15 cases were performed the ligation combined with the high frequency electroresection .Intraoperative bleeding occurred in 3 cases and no other complicntions such as perforation occurred .Conclusion The clinical manifestations of upper gastrointestinal HP have no specificity .Gastroendoscopy combimed with EUS has the important value in the diagnosis and endoscopis therapy .En-doscopic EMR and ligation combined with the high frequency electroresection are the safe and effective means for treating upper gastrointestinal HP .
