Changes of rat body weight with time following operations among the four groups. A: Obstructive jaundice (OJ) rats ate markedly less food and there was a slowly increasing trend of body weight between the 1^st, 8^th and 15^th day (P = 0.155). On the contrary, weight gain was more significant in sham operation (SH) rats compared with that in OJ rats on the 8^th and 15^th day. After relief of OJ, the appetite of internal biliary drainage (ID) rats recovered and the body weight of ID rats on the 15^th day became significantly higher than that on the 8^th day. ^bP < 0.01 vs OJ; ^cP < 0.05 vs SH; ^fP < 0.01 vs external biliary drainage (ED); B: Weight loss was observed in ED rats and the body weight on day 15 was significantly lower than that on the 1^st or 8^th day. ^gP < 0.05, ^hP < 0.01 vs D15.
