Abstract:
Objective To evaluate effects of alimentary reconstruction procedures (integral continual jejunal interposition, Billroth Ⅱ and isolated jejunal interposition) after subtotal gastrectomy on postoperative plasma gastrin, motilin and cholecystokinin. Methods Twenty-four dogs were divided into 3 groups undergoing distal subtotal gastrectomy and three different digestive tract reconstruction (integral continual jejunal interposition, Billroth Ⅱ and isolated jejunal interposition). The concentration of plasma gastrin, motilin and cholecystokinin were detected by enzyme-linked immunosorbent assay before and after operation. Results Two months after operation, plasma gastrin level of the integral continual jejunal interposition group (2. 2 ±0. 7 ) ng/L, ( 3.9 ± 0. 8 ) ng/L was significantly lower than that of preoperative both in fasting and postprandial state (3.8 ± 1.0) ng/L, (5.3 ± 1.6) ng/L, all P ＜0.05, but was significantly higher than other two groups in postprandial state (2. 7 ± 1.0) ng/L, (3.6 ±0. 6) ng/L, P ＜0. 05. Two months after operation, plasma motilin concentration of integral continual jejunal interposition group (577 ±204) ng/L, (1003 ± 209) ng/L were significantly higher than that of preoperative both in fasting and postprandial (429 ± 128) ng/L, (854 ± 218 ) ng/L, P ＜ 0. 05. The postoperative plasma motilin of integral continual jejunal interposition group ( 1003 ± 209 ) ng/L was significantly higher than other two groups in postprandial state (840 ±205) ng/L, (986 ± 189) ng/L, P ＜0. 05. Two months after operation,plasma cholecystokinin concentration of integral continual jejunal interposition group ( 19.6 ± 2.0 ) ng/Lwere significantly higher than that of preoperative both in postprandial ( 19.0 ± 2. 0) ng/L, P ＜ 0. 05. The postoperative plasma cholecystokinin of integral continual jejunal interposition group ( 19. 6 ± 2. 0) ng/L was significantly lower than other two groups (22.2 ± 2. 1 ) ng/L, (20. 1 ± 2. 5 ) ng/L, P ＜ 0. 05. Conclusion Integral continual jejunal interposition after distal gastrectomy maintains the postoperative plasma motilin and gastrin in a relatively higher level and decreases the concentration of plasma cholecystokinin.
