Gastric cancer is a rare condition affecting patients with familial adenomatous polyposis (FAP). The mainstay of treatment is total gastrectomy. Since duodenal cancer is the most common cause of death after total colectomy in FAP, endoscopic surveillance for duodenal cancer is mandatory. Here, we describe the use of an isoperistaltic jejunal loop interposition technique to reconstruct the digestive tract after total gastrectomy in 2 patients with FAP. There were no early or late complications. Both patients are still alive and in good clinical condition. They did not experience weight loss or symptoms of dumping syndrome. Duodenal endoscopic surveillance after this technique was easier than after the classical Roux-en-Y reconstruction. Hence, regular follow-up was possible for both patients.

家族性腺瘤性息肉病患者胃癌全胃切除术后等蠕动空肠环插入术

胃癌是一种影响家族性腺瘤性息肉病 (FAP) 患者的罕见疾病。主要治疗方法是全胃切除术。由于十二指肠癌是 FAP 全结肠切除术后最常见的死亡原因，因此对十二指肠癌进行内镜监测是强制性的。在这里，我们描述了在 2 名 FAP 患者全胃切除术后使用等蠕动空肠袢插入技术重建消化道。没有早期或晚期并发症。两名患者都还活着，临床状况良好。他们没有体重减轻或倾倒综合征的症状。这种技术后的十二指肠内窥镜监测比经典的 Roux-en-Y 重建后更容易。因此，对两名患者进行定期随访是可能的。
