[Endoscopic study of the uterine cavity. Diagnostic and therapeutic hysteroscopy. I. General aspects]. / Estudio endoscópico de la cavidad uterina. Histeroscopia diagnóstica y terapéutica. I. Aspectos generales.

We present our experience in the first 236 hysteroscopic procedures in Pontificia Universidad Católica of Chile. 219 were performed as part of infertility study and 17 were performed for other reasons. The surgical technique, type of anesthesia, distension procedures and complications are described. The correlation between hysterosalpingographic diagnosis and endoscopic vision is established. The preoperative diagnosis was confirmed in 82% of the uterine cavity synechiae, 72% of the cervical synechiae, 67% of polyps and/or myomas, and in 100% of uterine malformations. Myomas and/or polyps were found in 12% of normal appearing hysterosalpingograms.

The hysteroscopic study and treatment of 136 infertile patients with synechiae of the uterine cavity and/or cervix is presented. The preoperative diagnosis was established by hysterosalpingography. The correlation between the diagnosis by hysterosalpingography and hysteroscopy was 72% for synechiae of the cervix; 73% for mild synechiae; 83.3% for moderate synechiae and 75% for severe synechiae of the uterine cavity. All findings of synechiae were treated hysteroscopically. The history of abortion and puerperal infection were among the most commonly found amnestic data related to the genesis of synechiae. The pregnancy rate was 70%, and 87.5% delivered term pregnancies in patients who did not have other associated factors of infertility.
