title: [Monofilaments in digestive system surgery].
abstract: The most important physical and chemical properties of the new synthetic absorbable suture materials are shown. Particularly this paper make a comparison between multifilament and monofilament suture wire from the point of view of tensile strength, "in vivo" tensile strength retention, reabsorbability, foreseeability of the reabsorption time of the capillarity. On these theoretical basis the AA. think that actually the best suture wire for the gastrointestinal surgery must be a synthetic absorbable monofilament suture material. Clinical and experimental experience of the AA. utilizing in the surgery of the gastrointestinal tract a copolymer monofilament of the glycolic acid and of the trimethylene carbonate (polyglyconate-Maxon), resorbable by not-enzymatic hydrolysis in about 180 days are described. The clinical experience was acquired performing 43 manual gastroenteric anastomosis by polyglyconate suture material and making an endoscopic follow-up in 19 cases (12 oesophago-jejunal anastomoses and 7 colo-rectal anastomoses). The experimental study consist of 30 enteric anastomosis performed on rats. The results evaluation was made from three points of views: bacteriological, optical diffuse light microscopy and electronic transmission microscopy. The conclusions of the clinical and experimental studies are favourable for the use the polyglyconate suture wire in digestive surgery, and confirm also "in vivo" its theoretical properties.
