Intestinal manipulation (IM) during abdominal surgery triggers the influx of inflammatory cells, leading to postoperative ileus. Prevention of this local muscle inflammation, using intercellular adhesion molecule‐1 (ICAM‐1) and leukocyte function‐associated antigen‐1‐specific antibodies, has been shown to shorten postoperative ileus. However, the therapeutic use of antibodies has considerable disadvantages. The aim of the current study was to evaluate the effect of ISIS‐3082, a mouse‐specific ICAM‐1 antisense oligonucleotide, on postoperative ileus in mice. Mice underwent a laparotomy or a laparotomy combined with IM after treatment with ICAM‐1 antibodies, 0.1–10 mg kg−1 ISIS‐3082, saline or ISIS‐8997 (scrambled control antisense oligonucleotides, 1 and 3 mg kg−1). At 24 h after surgery, gastric emptying of a 99mTC labelled semi‐liquid meal was determined using scintigraphy. Intestinal inflammation was assessed by myeloperoxidase (MPO) activity in ileal muscle whole mounts. IM significantly reduced gastric emptying compared to laparotomy. Pretreatment with ISIS‐3082 (0.1–1 mg kg−1) as well as ICAM‐1 antibodies (10 mg kg−1), but not ISIS‐8997 or saline, improved gastric emptying in a dose‐dependent manner. This effect diminished with higher doses of ISIS‐3082 (3–10 mg kg−1). Similarly, ISIS‐3082 (0.1–1 mg kg−1) and ICAM‐1 antibodies, but not ISIS‐8997 or higher doses of ISIS‐3082 (3–10 mg kg−1), reduced manipulation‐induced inflammation. Immunohistochemistry showed reduction of ICAM‐1 expression with ISIS‐3082 only. ISIS‐3082 pretreatment prevents postoperative ileus in mice by reduction of manipulation‐induced local intestinal muscle inflammation. Our data suggest that targeting ICAM‐1 using antisense oligonucleotides may represent a new therapeutic approach to the prevention of postoperative ileus.
