LigaSure vessel sealing system in vaginal hysterectomy: safety, efficacy and limitations

The aim of this study is to compare vaginal hysterectomy performed with standard technique versus the one performed with LigaSure. Observational-longitudinal-cohort study on 42 women candidates to vaginal hysterectomy because of benign uterine pathology. Outcome variables, methods of analysis, inclusion and exclusion criteria were determined prospectively. Eligible patients were subdivided in Group-A (LigaSure-21 patients), or in Group-B (classical-21 patients). Group-A was divided into Subgroup-A1 (10 patients) and Subgroup-A2 (11 patients), depending on the point where the stump of the uterosacral-ligament was transfixed: Subgroup-A1 at cervical portion, Subgroup-A2 at intermediate portion. For all patients were reported: pre-post surgery haemoglobin and hematocrit, number of sutures, duration of intervention and blood loss, NRS-score on first/third post-operative days. All patients underwent gynaecological examination 30 and 180 days after surgery. General characteristics did not show significant differences between the two groups. Statistically significant differences emerged from the comparison between Group-A versus Group-B in terms of: intraoperative bleeding, post-operative value of haemoglobin, Delta-Hb, number of sutures, surgical time, pain at first and third post-operative day. The 180 days follow-up demonstrated four cases of vaginal vault prolapse, only in the Subgroup-A1 related to thermal damage of the uterosacral ligament. LigaSure vessel sealing system is a safe alternative for securing pedicles in vaginal hysterectomy with significant improvement in patients outcome. Following vaginal vault prolapse, we determined the optimal fixation-site to perform the colposuspension in the intermediate portion of the uterosacral-ligament, especially if the cervical portion received a thermal damage, as occurs during the LigaSure use.
