目的：探讨胃癌误诊误治的原因及其对策。方法：对误诊误治所致术后复发的23例胃癌进行回顾性临床分析。结果：临床误诊为胃溃疡出血7例，胃穿孔1例，胃镜检查误诊为良性胃溃疡15例。23例均行单纯胃大部切除术，术后病理检验误诊为胃溃疡2例，误诊时间最长35个月。术后复发时间平均16．6个月，复发后平均生存6．3个月。结论：误诊误治导致胃癌术后腹腔淋巴结、残胃和腹膜复发，影响患者的预后，提高胃癌早期诊断的认识，完善肿瘤诊治规范，可望防止误诊误治，减少术后复发。
Objective: To explore the causes and countermeasures of misdiagnosis and mistreatment of gastric cancer. Methods: Retrospective clinical analysis was performed on 23 cases of gastric cancer recurrence after misdiagnosis and mistreatment. Results: The clinical misdiagnosis was gastric ulcer bleeding in 7 cases, gastric perforation in 1 case, gastroscopy misdiagnosed as benign gastric ulcer in 15 cases. All of the 23 patients underwent simple gastrectomy. Postoperative pathological examinations were misdiagnosed as gastric ulcer in 2 cases. The misdiagnosis time was 35 months. The average time to relapse was 16.6 months, and the average survival time was 6.3 months after relapse. Conclusion: Misdiagnosis and mistreatment result in the recurrence of abdominal lymph nodes, residual stomach and peritoneum after gastric cancer. It affects the prognosis of patients, improves the understanding of early diagnosis of gastric cancer, and improves the diagnosis and treatment of cancer. It is expected to prevent misdiagnosis and mistreatment and reduce postoperative recurrence.
