Endoscopic Instrumentation Linked to Insulation Failures

After 10 uses, robotic instrumentation has higher rate of insulation failures than laparoscopic

TUESDAY, Aug. 2 (HealthDay News) -- Robotic and laparoscopic endoscopic instrumentations -- particularly robotic -- are associated with high incidence and prevalence of insulation failure (IF) after 10 procedures, according to a study published in the August issue of the American Journal of Obstetrics & Gynecology.

Mercedes Espada, M.D., from the Hospital Quirón Madrid in Spain, and colleagues investigated the incidence, prevalence, and location of IF in laparoscopic and robotic instruments. A total of 78 robotic and 298 laparoscopic instruments were tested at 20 W and 2.64 kV in phase A, and 60 robotic and 308 laparoscopic instruments were tested at 20 W/1 kV and 20 W/4.2 kV, respectively, in phase B.

The investigators found that the robotic group had a significantly higher prevalence (32 versus 13 percent) and incidence (80 versus 36 percent) of IF after 10 uses in phase A compared to the laparoscopy group. In phase B, 81.7 percent of robotic, and 19.5 percent of laparoscopic instruments demonstrated IF.

"There is a high incidence and prevalence of IF in robotic and laparoscopic electrosurgical instruments, even when tested according to manufacturer specifications of voltage," the authors write.
