[Pathological observations on fallopian tubes after sterilization]

From animal experiments and clinical observation of 130 cases of tubal anastomosis, it has shown that the dilatation of salpinx and adhesion of pelvic organs may occur after ligation of oviduct tube. The present study showed that: (1) tubal dilatation is the result of simple hydrosalpinx and is related to inadequate location of tubal ligation; (2) the mechanical stimulus caused by rough ligation end and large scar is an important factor in producing adhesion of pelvic organs; (3) delicate and gentle operation and choosing isthmus portion to ligate is helpful in prevention of the above changes.
