\n\t\t\tRandomised Trial of Time Efficiency of Electrosurgical Devices: LigaSureTM<\/sup> Blunt Tip & LigaSureTM<\/sup> XP\t<\/h1>\n\t\t\t

Background<\/h3>\t\t\t\n\t\t\t\t

This randomised trial compared two Medtronic electrosurgical devices to evaluate whether a
newer, more costly technology provides any benefit in terms of time e\ufb03ciency. The LigaSure\u2122 LF1837 (LF) was the standard device used in hysterectomy procedures before the trial. The newer LigaSure\u2122 XP device features a longer jaw length and enhanced seal strength, requiring fewer seals during procedures. The trial aimed to determine whether these features resulted in shorter operating times compared to the current practice.<\/p>\n\t\t\t

Objective<\/h3>\t\t\t\n\t\t\t\t

To compare the surgical operating times between LigaSure\u2122 XP (XP) and the standard energy device, LigaSure\u2122 Blunt Tip (LF), in laparoscopic hysterectomy procedures. The study also aimed to assess the potential health economics di\ufb00erence from a private hospital payer perspective.<\/p>\n\t\t\t\t\"GetAttachmentThumbnail\"\n\t\t\t

Method<\/h3>\t\t\t\n\t\t\t\t

A total of 24 devices were tested: 12 LF and 12 XP, which were randomly assigned to consecutive cases. All surgeries were performed for benign conditions and involved total laparoscopic hysterectomy (TLH) with bilateral salpingo-oophorectomy (BSO). The “electrosurgical use time” was defined as the period from the first activation of the LigaSure\u2122 device at the round ligament to the start of vaginal cu\ufb00 closure. This standardised measurement excluded other patient-related factors (i.e. adhesions).<\/p>\n\t\t\t

Results<\/h3>\t\t\t\n\t\t\t\t

The average age (57.7 vs. 58.7 years), height (1.64m vs. 1.64m), weight (76kg vs. 74.4kg), and BMI (28.1 vs. 27.4) were similar between the LF and XP groups, respectively. Uterine weight (147g vs. 119g) was also comparable, with no statistically significant or clinically meaningful di\ufb00erences. The electrosurgical use time was significantly shorter for the XP group (20.3 minutes) compared to the LF group (26.6 minutes) (p < 0.01).<\/p>\n\t\t\t

Conclusions<\/h3>\t\t\t\n\t\t\t\t

The XP device resulted in a time saving of over six minutes per case. Using private health
insurance data, the average cost per minute in the operating theatre for benign hysterectomy is $62.43 (Private Hospital Data Bureau: Annual Report 2023-24, Department of Health and Aged Care). This translates to a potential time-related cost saving of $390 per case. The savings in operating time su\ufb03ciently o\ufb00set the additional cost of the newer device, and further cost reductions may be realized from a private hospital payer perspective. This could translate to greater benefit in more complex surgery requiring increased device use.<\/p>\n\t\t\t
