Clinical Analysis Of Gastric Stump Cancer: A Report Of 47 Cases

【Objective】: To elucidate gastric stump carcinoma's clinical characteristics and study its occurrence mechanism,also investigate the pattern of lymph node metastasis and optimal surgery for patients with gastric stamp carcinoma.【Methods】:The clinical data of 47 case admitted during the period from January 1999 to January 2009 are analyzed restrospectively.【Results】:Gastric stamp carcinomas often rise after subtotal gastrectomy with BillrothII and males is common. The focus lies to gastric mucosa adjacent to anstomotic stoma.In this group of cases,pathological stage I,II,IIIandVI is4.5.18.20,Among them,31caes undergo curative resection,and the metastasis rates of lymph node of N1(group1,2,3,4,7,10,11)is the highest(54.6%).All 2 patients undergoing non-resection only died within one year,and the 1.3. 5-yeat survival rates of patient (n=31) with curative resection were significantly better than those of patients(n=14)with palliatine gastrectomy.【Conclusions】:(1)Proliferative activity of duodenal reflux and Hp should be responsible for the high incidence of patients with gastric cancer in the Long-standing gastrectomy patients.In order to decrease the incidence of stump carcinoma effectively,it seems reasonable to perform reconstruction procedures(e.g,B-I or Roux-en-Y anastomosis)for those withgastrectomy.(2)The five-year survival rate of primary gastric cancer after resection and adequate lymphadenectomy is better than those of patient with palliatine gastrectomy . (3)patient with gastric stump carcinoma can gain better prognosis by undergoing curative resection with adequale lymphadenectomy and early diagnose and precaution.
