So does any condition interferingwith the normal peristalsis of the tube. Chronic salpingitis,therefore, is often found associated with and preceding tubalpregnane}. Peritoneal adhesions constricting or distorting the tubes andcongenital narrowness of their caliber may also obstruct thetubal canals. A diverticulum in the tube, an accessory tubalcanal, external transmigration of the ovum, accessory abdominalostia, and atresia of the tube have been noted in connection with ectopic gestation. Clinical History.— In each of the situations noted above the course of gestation may be: somewhat different, and each may present an individual clinical picture on account of the difference in the surrounding anatomical structures which are involved.
