本文报告使用纤维胃镜检查手术后胃135例观察结果。吻合口炎多与其它病变并存,单纯性吻合口炎较少。大量胆汁返流与残胃炎及吻合口浅表炎症、溃疡的发病密切有关。对纤维胃镜与 X 线钡餐检查资料俱全的87例进行对比分析,结果表明纤维胃镜检查明显优越于 X 线钡餐检查,尤其对浅表炎性病变更具有价值。 This article reports the use of fiberoptic gastroscopy for the observation of 135 cases of stomach after surgery. Anastomotic stomatitis and other lesions coexist, and simple anastomotic stomatitis is less. A large amount of bile reflux is closely related to residual gastritis and superficial inflammation of the anastomosis and the incidence of ulcers. A comparative analysis of 87 patients with fiberoptic gastroscopy and X-ray barium examination data revealed that the gastroscopy was significantly superior to X-ray barium examination, especially for superficial inflammatory disease changes.
