Purpose: To evaluate the safety and efficacy of a new vessel-sealing device (LigaSure) for laparoscopic varicocelectomy.
Materials And Methods: To evaluate the safty, after elective varicocelectomy, the internal spermatic veins (n = 8) were sealed ex vivo with a 5-mm laparoscopic Maryland-style LigaSure (LigaSure Lap), and bursting pressures were measured. To evaluate the efficacy, a retrospective review of our clinical experience with LigaSure (n = 13) and clip (n = 13) in laparoscopic bilatelal varicocelectomy from June 2000 to October 2002 was performed and certain parameters were abstracted, including operative time, estimated blood loss and perioperative complications.
Result: In the ex vivo study the mean varicocele vessele diameter was 2.5 +/- 0.8 mm (mean +/- SD) and bursting pressure was 449 +/- 95.2 mmHg. Six were burst in normal vessel walls at the average bursting pressure of 442 mmHg and two in the occlusions at the average bursting pressure of 508 mmHg. The difference was not statistically significant. Reliable vessel sealing was achieved in all the patients. The mean operative time showed significant decrease in the LigaSure group compared with the clip group, 70 +/- 20 minutes versus 117 +/- 27 minutes (p < 0.05). Estimated blood loss was minimal and no perioperative complications occurred in both groups.
Conclusions: Our study suggests that a vessel-sealing device appears to be a safe and feasible alternative to the clip in laparoscopic varicocelectomy. It offers the advantage of reducing operative time.

Background: Hysterectomy is one of the most common surgical procedures performed in the United States and most are now being performed in a minimally invasive approach. Electrosurgery and vessel sealing devices are needed in order to provide hemostasis and vascular coaptation; however, there is no guiding evidence and limited recommendations for the use of the currently available devices for laparoscopic hysterectomy. The purpose of this study is to provide a systematic review of electrosurgical devices used in benign hysterectomy and perform a meta-analysis to find the overall effect of various outcomes.

Importance: Electrosurgical vessel sealing devices for vaginal hysterectomy have demonstrated reduced postoperative pain. This modality, however, has not been evaluated in patients undergoing vaginal hysterectomy with pelvic reconstruction.
Objective: The aim of the study was to describe postoperative pain levels utilizing the LigaSure vessel sealing device for vaginal hysterectomy in patients undergoing major reconstructive surgery.

Surgical cutting with electrosurgical tools facilitates tissue dissection and vessel sealing, preventing blood loss. The extent of tissue necrosis due to temperature elevations is dependent on the cutting technique, device design, coating properties and power settings, but the influence of these parameters is not fully understood. Here we conduct a comprehensive comparative analysis of thermal damage comparing (1) manual user-controlled and robotic electrosurgical cutting approaches for (2) varying electrodes and coatings, and power settings.

Background: Bipolar vessel-sealing devices (BVSD) have been used for muscle transection in canine limb amputations; however, a retrospective study of their use, and particularly the short-term complications, has not yet been reported.
Objectives: To describe the use of a BVSD as the main method for muscle transection in canine limb amputations and to report the incidence of short-term incisional complications following these surgeries.
Animals And Procedure: Medical records of dogs undergoing limb amputations using a BVSD from January 2017 to December 2018 were reviewed for demographics, preoperative findings, intraoperative complications, and short-term outcomes.
