The effects of vagotomy on bacterial translocation: an experimental study
The effects of truncal vagotomy and proximal gastric vagotomy on bacterial translocation in rats were investigated in this experiment. The rats were divided into three groups. Only esophageal and gastric manipulations were performed in the control group (Group I). The anterior and posterior vagi were found and 0.5- to 1-cm pieces were taken out in the truncal vagotomy + pyloric dilatation group. In addition, pyloric dilatation was performed using a Fogarty catheter (Group II). The branches of the vagi, which lead to the rumen and corpus, were first tied with 5/O silk and then resected in the proximal gastric vagotomy group (Group III). All animals were sacrificed on the 7th day. Qualitative and quantitative tissue cultures of cecum, liver, spleen, mesenteric lymph node, and blood from vena cava were taken and a tissue sample from the ileum was obtained for histopathological examination with light microscopy. At the end of microbiologic study, the bacterial concentration on the cecal wall was 10.68 x 10(8) in the truncal vagotomy group, while it was 0.53 x 10(8) in the proximal gastric vagotomy group. Bacterial translocation was observed more in vagotomy groups than in control groups on the mesenteric lymph node, liver, and sple...Continue Reading
