Popis: Background/purpose We developed EUS-guided double-balloon occluded gastrojejunostomy (EPASS) for gastric drainage tract obstruction. The success of EPASS depends on the proximity of the stomach and the gastrointestinal (GI) tract near the ligament of Treitz. The aim of this study is to clarify the GI anatomy near the ligament of Treitz. Methods One thousand and sixteen cases imaged upper GI radiography using barium were retrospectively evaluated. Morphologically, the GI tract running near the ligament of Treitz was divided in three types: Type I: The 4th portion of the duodenum (D4) approaches the stomach; Type II: D4 does not approach the stomach; Type III: D4 forms a loop to the jejunum. The minimum distance between the stomach and the GI tract near the ligament of Treitz was measured. Results Based on the morphological classification, 74.6% in the study group was classified in Type I, 22.0% in Type II, and 3.3% in Type III, respectively. The median minimum distance in Type II/III group were significantly longer, compared with the Type I (P Conclusions The GI anatomy near the ligament of Treitz was clarified using upper GI radiography. It is divided into three patterns, and one-fourth of cases may have difficulty in EUS-guided gastrojejunostomy.
