Objective     To investigate the feasibility of ileocecal interposition graft as substitute for pylorus after conventional distal gastrectomy.      Methods     Fourteen Bama minipigs were randomized into sham laparotomy group and ileocecal interposition graft group (group Ⅱ) after subtotal distal gastrectomy (n=7 in each group). Electrogastrogram was recorded by BL-410 biologic experiment enginery system for 60 min at 2

nd

4

th

6

th

month after operation. The mean frequency of slow wave (MFSW) and the index of abnormal slow wave (IASW) were calculated and compared.      Results     After operation

MFSW was of no great changes and of no statistical difference. At  2

nd

4

th

month after operation

IASW in group Ⅱ was

higher than that in sham laparotomy group (P0.01 at 2

P0.05 at 4

while at 6

th

month

no difference was among the two groups.      Conclusion     Ileocecal interposition graft as substitute for pylorus after conventional distal gastrectomy is feasible.
