胃切除术后复发性溃疡的主要原因有分泌酸的粘膜切除不足及不彻底地胃窦切除残留胃窦粘膜。前者通过X线钡餐检查,发现残胃很大,后者常通过纤维内镜在吻合口近端小弯侧或十二指肠残留顶部取粘膜活检,以发现是否残留胃窦粘膜。 “Bombesin”一种可以刺激胃窦G细胞分泌胃泌素的肽类物质,亦可确定有无胃窦粘膜
The main causes of recurrent ulcers after gastrectomy are insufficient secretion of acid mucosal resection and incomplete gastric antrum resection of residual gastric antral mucosa. The former through the X-ray barium meal examination found a large residual stomach, the latter often through fiber endoscopy in the proximal end of the anastomotic less curved side or duodenal residual mucosa biopsy to find out whether the residual antral mucosa. “Bombesin,” a peptide substance that stimulates gastrin secretion in gastric antral G cells, can also determine whether there is gastric mucosa in the antrum.
