The modern absorbable suture materials are well introduced in colonic surgery. Surgeon's intension is to reduce foreign body reactions by using small sized sutures and will be limited by the suture holding capacity of the tissue. Suture holding capacity of the human colon is about 9 +/- 2 N. Wound healing of colon anastomoses normally lasts 10 to 12 days. The braided absorbable suture materials Dexon, Dexon plus and Vicryl (size 3-0 USP) have a knot breaking strength of about 10 N after 12 days implantation in the human colon, the monofilament absorbable sutures PDS and Maxon have about 20 N resting strength after implantation. These results document that the size 3-0 USP (2-metric) should be the lowest limit for the braided absorbable suture materials used in colonic surgery.
现代可吸收缝合材料在结肠手术中已得到充分介绍。外科医生的意图是通过使用小号缝线来减少异物反应，但这会受到组织对缝线握持力的限制。人体结肠对缝线的握持力约为9±2牛。结肠吻合口的伤口愈合通常持续10至12天。编织可吸收缝合材料Dexon、Dexon plus和Vicryl（3-0 USP规格）在植入人体结肠12天后的结断裂强度约为10牛，单丝可吸收缝线PDS和Maxon植入后的静息强度约为20牛。这些结果表明，3-0 USP（2-公制）规格应是结肠手术中使用的编织可吸收缝合材料的最低限度。
