Objective:To study the effect of endoscopic ligation for early stage carcinoma and benign polyp of stomach.Methods:The early stage cancer in situ and polyp (d＜1.0cm) of stomach were sucked and resected with the endoscopic ligation advice which is used in esophgeal varice ligation.The remained tissue were observed histopathologically whether there had any malignant cell in it and follow-up of 3～6 months was mode by endoscopy.Results:Form 1996 to 1999,56 patients received endscopic ligation.Of these patients,8 cases had gastric early carcinoma (2 cases superficial flat type,4 cases superficial elevated type,2 cases carcinoma in situ),48 cases had gastric benign polyps (38 cases infammatory polpy,10 cases polpypous adeoma).After the endscopic ligation,no malignnant cell was found in remained tissues and no polyp recured within the follow-up period.So this method was demonstrated to be safe,cheap and good effective method for early stage carcinoma,minicarcinoma,carcinoma in situ and benign polyp (d＜1.5cm) of stomach.It deserves being widespread.
