Conventional unabsorbable suture material can lead to gall salt precipitation and thus to gall stone formation. Catgut segments may cause identical sequelae if they are displaced into the lumen of the biliary tract under certain conditions. The reaction of polyglycolic acid (PGA) as well as of polyglactin material was tested under in-vitro conditions. PGA material disintegrated within 9 weeks; precipitation of gall salts was not observed. Polyglactin samples showed stable durability up to 22 weeks under the same conditions; firmly adherent small concrements could be demonstrated. In accordance with these observations, PGA material seems to be the most appropriate suture material for the surgery of the biliary tract at the time being.
传统的不可吸收缝合材料可导致胆盐沉淀，进而导致胆结石形成。如果肠线节段在某些情况下移位到胆道腔内，可能会引起相同的后遗症。在体外条件下测试了聚乙醇酸（PGA）以及聚乳酸材料的反应。PGA材料在9周内分解；未观察到胆盐沉淀。在相同条件下，聚乳酸样品显示出长达22周的稳定耐久性；可以证明有牢固附着的小结石。根据这些观察结果，PGA材料目前似乎是胆道手术中最合适的缝合材料。
