Abstract:
Objective To evaluate the significance of endoscopic ultrasonography (EUS) in the diagnosis of linitis plastica.Methods Twenty one cases of linitis plastica were examined by EUS; the results were compared with those of conventional gastroscopy with biopsies, gastrointestinal X ray, CT, and the postoperative pathological findings.Results The ultrasonography of lanitis plastica manifested as 1. The second, third and fourth layers of stomach wall thickened at the lesion site, and disappearance of the layered structure of the invaded stomach wall, the thickened stomach wall have the thickness of (1 68?0 37) cm in average; 2. 95 24% of the lesion shows hypo echoic patterns; 3. The confines of lesion in EUS are beyond those of the conventional endoscopies. 4. 85 7% of the lesion tends to grow along the transverse axis of stomach in continuous distribution; 5.The border of lesion is readily distinguished, but in enlarged picture blurred boundary is the evidence of infiltrative growth of the lesion. The coincidence rate of ESU in diagnosing linitis plastica is 90 48%, that is evidently higher than that of conventional endoscopy 52 38% ( P =0 0095), gastrointestinal X ray 61 11% ( P =0 0396) and CT 35 29% ( P =0 0059). Compared with the postoperative pathological diagnosis, the diagnostic accuracy of T, N staging by ESU are 80 95% and 85 71% respectively. The accuracy of predicting resectability by ESU was 71 43% (15/21).Conclusion ESU has the superiority of raising the diagnostic accuracy and is helpful in predicting the border of lesion and the resectability.
