Diagnostic laparoscopy is needed after abnormal hysterosalpingography to prevent over-treatment with IVF.

The additional value of laparoscopy was investigated with respect to diagnosis and further treatment decisions after abnormal hysterosalpingography (HSG) and prior to intrauterine insemination (IUI). In a retrospective chart review, the number of patients with abnormal HSG who finally need IVF treatment based on the laparoscopic findings was evaluated. Independent of whether HSG showed unilateral or bilateral tubal pathology, IVF was the final treatment decision in only 74 (29%) cases where laparoscopy showed bilateral abnormalities. IUI treatment was advised in 121 (48%) patients with laparoscopically normal findings or unilateral abnormalities. Fifty-seven (23%) patients were treated by IUI after receiving laparoscopic surgery of unilateral adhesions or endometriosis stage 1-2 or after ablation of moderate-severe endometriosis in a second operation. In cases of bilateral tubal abnormalities revealed by HSG, bilateral pathology was confirmed by laparoscopy in at least 58 (46%) patients and they were advised to be treated by IVF after laparoscopy. The agreement between abnormalities found by HSG and abnormalities found by laparoscopy requiring IVF treatment was poor even when HSG showed bilateral pathology. Based on these findings, it is concluded that laparoscopy is mandatory after abnormal HSG findings in the work-up prior to IUI to prevent over-treatment with IVF.
