Endosonographic findings of gastric ectopic pancreas: A single center experience

Abstract

The characteristic EUS features of ectopic pancreas are indistinct borders, lobulated margins, presence of anechoic duct-like structures, a mural growth pattern, and localization within two or more layers. These EUS features are potentially useful for differentiating ectopic pancreas from other mesenchymal tumors in the stomach.

Therapeutic Management of Submucosal Gastric Tumors: A Series of Six Cases with Ectopic Pancreas in the Stomach and Description of a Novel Endoscopic Full-Thickness Resection Technique of the Gastric Wall

“…Central umbilication or dimpling is a typical upper endoscopy finding indicative of ectopic pancreas, however, this finding has been described to be present in 34.6%-90.0% of cases [15,16]. A central umbilication was present in only one of our cases (case 4).…”

“…Previous reports described heterogeneous echogenity, indistinct borders and presence of anechoic duct-like structures to be typical EUS findings of ectopic pancreas [15,16]. Using EUS, Park et al distinguished between the well endoscopically removable superficialtype, where pancreatic tissue is located in the mucosal/submucosal layers and the deep-type, where endoscopic removal is less feasible [15].…”

“…Using EUS, Park et al distinguished between the well endoscopically removable superficialtype, where pancreatic tissue is located in the mucosal/submucosal layers and the deep-type, where endoscopic removal is less feasible [15]. EUS was performed in cases 3 and 5, heterogeneous echogenity was only seen in case 5.…”

“…Due to the diversity of gastric polyps and the difficulty of the diagnosis of heterotopic pancreas, we considered removal of the lesions when possible. Hase et al and Park et al limited the possibility of endoscopic removal to superficial lesions [15,20].…”

Endosonogragphic features of lesions suggesting gastricectopic pancreas: experience of a single tertiary center

“…Chen et al and Park et al reported the average diameter of gastric ectopic pancreas lesions as 12 mm (8-20 mm) and 14 mm (6-37 mm), respectively (7,14). Endoscopic appearances with central dimpling (or umbilication), orifice, or diverticulation with elevated edges are helpful in diagnosing probable ectopic pancreas preoperatively.…”
