Diagnostic hysteroscopic procedures had very low complication rates, so are safe procedures with which to evaluate intrauterine pathology. Operative hysteroscopic procedures were more risky, but the removal of polyps had a very low complication rate (12 times lower than synechiolysis). Half the complications were entry-related, so attention has to be paid to the method of entry with the hysteroscope (ie, no unnecessary dilation of cervix and introduction of the scope under direct vision). The other half of complications were related to surgeons' experience and type of procedure.
