《老友》专家门诊:我曾因腺瘤做了胃大部分切除术。目前残胃呈毕罗氏改变,吻合口通畅,未见异常。现在我要问的是溃疡好了,残胃应如何保护? “Old Friends” expert clinic: I had a major gastrectomy for adenomas. At present, the residual stomach was changed by Roche, and the anastomosis was smooth and no abnormalities were found. What I want to ask now is a good ulcer. How can the residual stomach be protected?
