It was reported in a journal article with title: a randomized trial comparing monopolar electrodes using glycine 1.5% with two different types of bipolar electrodes (tcris, versapoint) using saline, in hysteroscopic surgery the objectives of this randomized study was to compare three types of equipment during hysteroscopic resection.This study consist of 200 premenopausal women with menorrhagia caused by dysfunctional bleedings, fibroids, or polyps.Of which, 64 patients were randomized under the monopolar group (age: 44.9 ± 5.1), 71 patients in the tcr group (age: 43.2 ± 5.0), and 65 patients in the gynecare versapoint (ethicon) group (age: 44.6 ± 5.0).In the gynecare versapoint group, reported complications included lack of sterilized equipment (n-1) which lead to exclusion after randomization, technical problems during the procedure (n-4) which led to change of equipment and exclusion after randomization , and perforation (n-1).In conclusion, the results suggest that hysteroscopic resection in saline has an improved safety profile compared with resection in glycine 1.5%, because of the absence of reduction in serum sodium after intravasation.Although the authors observed more fluid deficit in the two saline groups, the authors did not observe any side effects.The tcris appears to be as effective as the monopolar equipment, concerning operating time and tissue removed.
