Silk is one of the most common sutures in surgical operations, because it is easy to
handle and apply the proper tension in tissues. It produces little but appreceable foreign
body reaction, when applied in tissues. With 38 tissues from cases of vasovasostomy,
who had different time lapsed, the chronological reaction of tissues are made in four
stages. It can be a guide for the determination when a silk suture is introduced in
tissue.
And, there is a general agreement in that, though silk is classified as non-absorbable,
it is fragmented and absorbed during a period of years. However, four case over 7
years, where the silk filaments maintain their shape and are still shining, are observed.
