Bacteriological and histological studies of puerperal fallopian tubes after tubal sterilisation.

Puerperal fallopian tubes were studied to detect bacteriological and histological changes after tubal sterilization to verify the clinical belief that morbidity after tubal ligation increases if performed beyond 24 hours when bacterial invasion of the fallopian tubes occurs progressively during the early days of puerperium. In 40 control cases histological evidence of salpingitis was observed in 4 cases (10%) and bacteriological culture was positive in 5 (12.5%). In the study group (n=160) histological evidence of salpingitis was observed in 15.1% of cases. In 87% of cases organisms could be isolated from both of the tubes and in the remainder of the cases organisms were cultured from 1 side. The same type of organisms from the cervical swabs were cultured in 77.4% of cases and different types occurred in 9.6% of cases. Only 38.7% of cases having positive tubal culture had histologcdal evidence of salpingitis whereas 9.7% of cases with sterile tubes showed histological evidence of salpingitis which is statistically significant at P < .001. It is concluded that the presence of microorganisms in the fallopian tubes early in puerperium does not seem to be related to delivery-sterilization interval. Neither does it significantly increase postoperative morbidity. Therefore tubal sterilization can be carrried out successfully and safely at any time during early puerperium after normal or instrummental delivery provided intrauterine manipulation was not done or anemia was not present.
