Germ line mutations in the E-cadherin gene account for approximately 30% to 50% of cases of hereditary diffuse gastric cancer syndrome. The estimated cumulative risk of gastric cancer by the age of 80 years in hereditary diffuse gastric cancer families is 67% for men and 83% for women, both of which carry a very poor prognosis if an early diagnosis is not made.
Two siblings with a strong family history of gastric cancer over at least 2 generations, including an aunt testing positive for the E-cadherin gene mutation, presented with positive results of the same mutation. Both siblings underwent a laparoscopic total gastrectomy. The postoperative period was uneventful. A 7-trocar totally laparoscopic surgical approach was used. The esophagojejunal anastomosis was created using a linear stapler in a lateral side-to-side manner. The biliopancreatic limb was 50 cm and the Roux limb was 75 cm in length.
Both siblings recovered without complications. Histologic evaluation revealed benign gastric tissue with no evidence of malignancy. Margins were clear of gastric mucosa. Prophylactic total gastrectomy eliminates the risk of gastric cancer in individuals with E-cadherin gene mutations. This procedure can be performed safely with a laparoscopic approach, resulting in excellent recovery and prognosis. Totally laparoscopic, lateral side-to-side esophagojejunal anastomosis using linear stapler creates an emerged lumen of both the esophagus and the jejunum that carries less risk of stricture, and reflux is prevented by a 75-cm-long Roux limb.
E-钙黏蛋白基因的种系突变约占遗传性弥漫性胃癌综合征病例的30%至50%。在遗传性弥漫性胃癌家族中,到80岁时胃癌的估计累积风险男性为67%,女性为83%,如果不能早期诊断,两者的预后都很差。
两名至少有两代胃癌家族史的兄弟姐妹,包括一名E-钙黏蛋白基因突变检测呈阳性的阿姨,检测出相同突变呈阳性。两名兄弟姐妹均接受了腹腔镜全胃切除术。术后恢复顺利。采用七孔全腹腔镜手术入路。使用直线缝合器以侧侧方式进行食管空肠吻合。胆胰支长度为50 cm,Roux支长度为75 cm。
两名兄弟姐妹均康复且无并发症。组织学评估显示胃组织良性,无恶性证据。切缘无胃黏膜。预防性全胃切除术可消除E-钙黏蛋白基因突变个体患胃癌的风险。该手术可通过腹腔镜方法安全进行,恢复良好且预后良好。使用直线缝合器进行全腹腔镜侧侧食管空肠吻合可形成食管和空肠的通畅管腔,狭窄风险较低,75 cm长的Roux支可防止反流。
