Malfuncionamiento de dispositivos quirúrgicos en cirugía pediátrica: estudio de la base de datos de experiencia de...

The increasing prevalence of laparoscopic surgery in pediatric cases underscores the critical importance of surgical device safety. However, research specifically examining device malfunctions in pediatric procedures remains limited. This retrospective database study aims to characterize the types of surgical stapler and energy device malfunctions encountered within the pediatric population.

This study is a retrospective analysis of the Manufacturer and User Facility Device Experience (MAUDE) database to identify reported malfunctions of energy devices (Harmonic, Thunderbeat, LigaSure, and CoolSeal) and surgical staplers in pediatric patients. The review encompassed reports from 2017 to 2023, focusing exclusively on patients aged 18 and under. Duplicate entries were eliminated by comparing patient age, incident date, and incident descriptions. Reports involving animal studies, adult patients, or those lacking patient age information were excluded from the analysis.

From a pool of 12,040 incident reports, 75 (0.61%) pertained to pediatric patients. After eliminating redundancies, 61 distinct cases were examined, encompassing malfunctions of surgical staplers (n = 31), Thunderbeat (n = 8), LigaSure (n = 20), and CoolSeal (n = 2). No deaths were recorded. A significant proportion (83.9%) of surgical stapler malfunctions involved the JustRight 5 mm Stapler, with the primary issue being failure to form a complete staple line. In LigaSure and CoolSeal, the predominant problem was sealing failure. Thunderbeat most frequently exhibited material fragmentation. Overall, 36.1% of the incidents resulted in patient injury, including bleeding (with one transfusion), bowel perforations, and bowel obstructions. Two cases required conversion to open surgery, and five necessitated additional surgical interventions. No root cause of malfunction was identified.

Although surgical devices undergo stringent safety protocols, malfunctions continue to be reported. The voluntary nature of the MAUDE database likely contributes to an underestimation of the true incidence of these events. Consequently, further research is warranted to comprehensively understand the nature and patient impact of device malfunctions.
