All data were analyzed by chi-square test. Results There was significant difference in symptom remission rate between Billroth Ⅱ subtotal gastrectomy, Roux-en-Y gastrojejunostomy and diverticulectomy, diverticulum inverting suture, sphincteroplasty of Oddi (χ~2= 21.269, 4.285, 12.914, 19.266, 3.938, P < 0.05). The difference in complication rate between Billroth Ⅱ subtotal gastrectomy, Roux-en-Y gastrojejunostomy and diverticulectomy, diverticulum inverting suture reached statistical significance (χ~2 =4.164, 9.166, 7.926,4.659, 4.858, P < 0.05).
