目的探讨残胃癌发病原因及其预防措施。方法对30例残胃癌的临床病理资料及化验结果进行回顾性分析。结果残胃癌以腺癌为主,多见于胃空肠吻合口,距第一次手术时间平均为16.8年;原行Billroth-Ⅱ式胃手术25例;残胃过大23例;不吸收缝线残存及异物反应19例;幽门螺杆菌(HP)感染20例。结论残胃癌的发生与十二指肠胃返流、胃内细菌过度生长、胃粘膜细胞营养环境改变、HP感染、残胃过大、不吸收缝线残存及距第一次手术时间长等因素有关。针对病因进行预防可望减少残胃癌的发病。
Objective To investigate the causes of gastric stump cancer and its preventive measures. Methods The clinical and pathological data and laboratory results of 30 cases of gastric residual carcinoma were retrospectively analyzed. Results Residual gastric cancer with adenocarcinoma, more common in the gastrojejunostomy, from the first operation time averaged 16.8 years; original line Billroth-Ⅱ-type gastric surgery in 25 cases; gastric remnant 23 cases; non-absorbable suture remnants And foreign body reaction in 19 cases; Helicobacter pylori (HP) infection in 20 cases. Conclusion The occurrence of residual gastric cancer is related to duodenal reflux, gastric bacterial overgrowth, changes in nutritional status of gastric mucosal cells, HP infection, excessive gastric remnant, non-absorbed suture remnant and long time to first surgery . Prevention of the cause is expected to reduce the incidence of residual gastric cancer.
