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.
