[en] 13 total gastrectomy (TG) cases with Roux-Y esophagojejunostomy and 12 subtotal gastrectomy (STG) cases with Billroth II gastrojejunostomy were examined with ^99mTc-PHY semisolid gastrointestinal imaging. The gastric half emptying time (GHET) and mean intestinal transit time (MITT) were analyzed. The GHET of normal subjects (NOR), STG and TG group were 33.7, 19.65 and 8.3 min respectively. There was significant difference between them (P<0.05). The MITT of NOR, STG and TG was 197.4, 202.58 and 237.22, respectively. The MITT in TG was significantly slower than that of NOR (P<0.01) and STG (P<0.05). This report provided a new valuable method for detecting gastrointestinal function disorders
