Objective: To evaluate our first experience with bipolar electrode (Verspoint, Johnson&Johnson) for transcervical surgery. Design: Prospective study. Setting: Department of Obstetrics and Gynecology, 1 st medical Faculty, Charles University, Pra- gue. Methods: Twenty procedures with bipolar electrode in normal saline as distension fluid were performed between September and November 1999. All 20 patients undervent office diagnostic hysteroscopy with biopsy sampling which demonstrated benign histological finding. We used Olympus operative 7 mm hysteroscope, Versapoint system with bipolar electrodes (twiz- le, spring, ball). In 13 cases we vaporized intrauterine polyps, in 4 cases we vaporized intrauterine submucous myoma (grade I-ESH), in 1 case we dissecated intrauterine septum and in 2 cases we performed intrauterine adhesiolysis. Local anesthesia-paracervical block was employed in 50% of procedures and general anesthesia was employed in 50% of cases. Results: The surgeon evaluated the degree of diffculty during the procedure as comfortible and easy to use in case of intrauterine polyp, intrauterine septum and intrauterine adhesions vapori- sation, as mild difficulty in submucous myoma to 2cm and moderate/severe difficulty in case of myoma vaporisation of more than 2 cm size. No complications were registered during or post procedure, we did not registered no sign of hyponatremia, no complains regarding pain or dis- comfort from patients. Conclusion: The adventage of Versapoint bipolar system for intrauterine operative hysteroscopy is the use of normal saline as distention fluid, which decreases pre and postoperative complicati- ons. We evaluated the vaporisation of pedunculate intrauterine patologies up to 2 cm as comfor- tible and easy to use. Combined to local anesthesia it appears to be a useful system for office hysteroscopy and transcervical surgery.
