A knitted tubular fabric is made from a synthetic yarn having a low capacity for liquid absorption; the ends of the tubular fabric are stitched closely so that the fabric will lie flat; the fabric is elongated in shape compared to its width and is used to provide a barrier around the edge of a surgical site, particularly in the abdomen, to be held in place by hand or by mechanical retractors to hold back away from the site other internal organs; the interior of the tubular fabric may be provided with a thin flexible liquid impervious sheet and which is held in place by parallel stitching along the length of the fabric.
