Incidence, significance and remission of tubal spasm during attempted hysteroscopic tubal sterilization.

Four hundred three attempted hysteroscopic tubal sterilizations were performed. Tubal spasm was encountered in 37 cases (9.2%) and prevented bilateral placement of tubal plugs in 16 of those cases. There was some evidence that glucagon was associated with a higher rate of remission and that women using barrier birth control methods experienced a lower incidence of tubal spasm. A number of other factors were found to be unrelated to tubal spasm and its remission.
