Salpingitis /Endosalpingitis is best confirmed by:

Both Hysteroscopy and laparoscopy cab give a confirmed diagnosis of salpingitis and endosalpingitis. Features of salpingitis such as pus extruding from the fimbrial end and adhesions can be visualized under direct laparoscopy. Although both the procedures cannot be used as a routine investigation, they are sure to confirm the diagnosis. Ref: Blaustein's Pathology of the Female Genital Tract By Ancel Blaustein, Robe J.
