Massive intestinal resection results in short-bowel syndrome (SBS) and is associated with an increased risk of infectious complications mainly caused by the egress of intestinal bacteria to distant organs, a process termed bacterial translocation (BT). The purpose of this experimental study in rats was to investigate in different models of SBS the impact of the type of intestinal resection on bacterial growth in the residual small bowel and on the occurrence of BT. SBS was created in 30 rats either by jejunal resection (JR), by ileal resection (IR) or by ileal resection including the ileocecal valve (IR+ICV). 10 animals underwent only a sham laparotomy (SL) and served as controls. Two weeks after the operative procedure, intestinal bacterial colonization and BT to the portal vein, vena cava, mesenteric lymph nodes, liver and spleen were determined. All resected animals showed a decreased weight gain and a significant bacterial overgrowth in the residual small bowel compared to the SL group. BT occurred after SL in 12 %, after JR in 70%, after IR in 58%, and was significantly less frequent (35 %) after IR+ICV, respectively. These experimental findings suggest that BT in SBS might be promoted by the intestinal bacterial overgrowth in the residual bowel, and the incidence of BT seems to be related to the presence or absence of the ileocecal valve.
