Objective: An analysis of ambulatory hysteroscopic procedures. Design: Retrospective study.Setting: Dept. of Obstetrics and Gynecology of the 1 st Faculty of Medicine, Charles University and the General Faculty Hospital, Apolinářská 18, Prague 2, Czech Republic. Methods: The sample consists of 225 patients who underwent ambulatory hysteroscopy, during the period between September 1999 to February 2000. The sample makes up 46.3% of the total number of hysteroscopies performed during that period. The procedures were performed under a paracervical block, only rarely in combination with analgesic sedation. Results: Indications for the procedure were most often abnormal uterine bleeding peri- or postme- nopausally, 51.2%, abnormal ultrasound findings in 9.8%, and endometrial polyps in 1.8%. In only 23.11% of cases, hysteroscopy was performed in the frame of TCS (transcervical surgery), the remaining procedures were diagnostic. The paracervical block was a great benefit to the comfort of the ambulatory procedures. In 93%, the procedure was evaluated as comfortable, in 4.8% there was discomfort, and in only 2.2% general anesthesia was used due to significant pain. We did not observe any early or late complications. Conclusion: Hysteroscopy can be performed as an ambulatory procedure, assuming quality quip- ment, an experienced surgeon, and properly administered local anesthesia. Our results demon- strate that hysteroscopy is not only a diagnostic procedure, but can be used for certain procedures in the area of TCS (with low or intermediate level of difficulty).
