Current interest in hepatic resections1 for various benign and malignant tumors has caused physicians at the Memorial Hospital to seek methods for decreasing blood loss. Bleeding from the point of suture has been most troublesome when the conventional eye-type needles and sutures are used. The doubled suture at the butt of the needle tears the thin liver capsule and vascular parenchyma, which results in massive blood loss during extended liver resections.
After four years of extensive clinical and laboratory trial at the Memorial Hospital with various sizes of sutures (000 to 3) and needles (1.0, 2.0, 3.0, and 3.5 in.) with blunt and taper points, our final choice was a size 1 chromic gut suture swaged on a half circle 3.5-in. taper point needle with a diameter of 0.046 in. This atraumatic suture permits an adequate amount of tissue to be encompassed in a single bite and is large
