Laparoscopic graspers cause identifiable tissue trauma during gallbladder surgery. This study establishes a reliable human model to histologically assess this grasper-induced injury.

Area of Science:

  • Surgical pathology
  • Minimally invasive surgery
  • Histology

Background:

  • Laparoscopic cholecystectomy involves tissue manipulation with surgical graspers.
  • Potential for iatrogenic tissue trauma from laparoscopic graspers is a concern.
  • A validated model is needed to assess grasper-tissue interactions.

Purpose of the Study:

  • To characterize the histopathological effects of laparoscopic grasper use.
  • To establish a reproducible human model for studying grasper-induced tissue trauma.
  • To test the hypothesis that graspers cause distinct histological injury.

Main Methods:

  • Prospective, blinded examination of gallbladder specimens from 19 patients.
  • Excision of grasped (sample) and non-grasped (control) gallbladder tissue.

  • Histological assessment for markers of crushed tissue injury by a blinded pathologist.

    • Main Results:

    • Pathologist correctly identified the grasped specimen in 13 of 19 cases (P = 0.003).
    • Focal thinning of the gallbladder wall was significantly more prevalent in grasped specimens (P = 0.0002).
    • Epithelial loss was significantly higher in grasped specimens (P < 0.0001).

    Conclusions:

    • Laparoscopic graspers induce histologically assessable tissue trauma.
    • The study successfully developed a reproducible human model for grasper-tissue interaction.
    • Findings confirm that graspers cause distinct tissue injury during laparoscopic procedures.
