Using the LigaSure vessel sealing device in the large uterus at laparoscopic hysterectomy
Objective:
To compare intraoperative hemorrhage and other operative parameters between patients with large and small weighted uterus who underwent laparoscopic hysterectomy (LH).
Materials And Methods:
Forty-six patients intending to have LH were divided into two groups according to uterine weight (group 1 > 300 grams vs. group 2 < 299 grams). Intraoperative blood loss, operating time, periopera- tive complications, and duration of hospitalization were compared.
Results:
Intraoperative blood loss was significantly higher in the large uterus group (group 1); 350 (227-454) ml vs. 250 (182-320) ml (p < 0.001). However, it was not significantly different between the groups in the laparoscopy step. Mean operating time was 90 (77-103) minutes and 80 (62-98) minutes in groups 1 and 2, respectively (p < 0.001) revealing ten-minute delay in group 1. Similarly, this was also not significantly different in the laparoscopy step. No significant differences were found between two groups; in terms of hemoglobin concentration decrease, major and minor complications, and hospitalization duration.
Conclusion:
The authors conclude that LigaSure can be safely used for LH in patients with a large uterus.

Overview of Blood Vessels
Arteries and Arterioles: Arteries are muscular and elastic vessels that primarily carry oxygenated blood from the heart to body tissues, except for the pulmonary artery, which carries deoxygenated blood. They have thick walls to withstand high pressure and contain a layer of muscle tissue, allowing them to expand or contract as...
