Hyperthermic intraperitoneal chemoperfusion (HIPEC) negatively impacts colonic anastomosis healing in rats. Both pre- and post-anastomosis HIPEC reduced bursting pressure and collagen, indicating impaired wound healing.

Area of Science:

  • Surgical oncology
  • Gastrointestinal surgery
  • Wound healing research

Background:

  • Controversy exists regarding hyperthermia and chemotherapy's effects on intestinal anastomosis healing.
  • Hyperthermic intraperitoneal chemoperfusion (HIPEC) is a treatment modality with potential impacts on surgical sites.

Purpose of the Study:

  • To investigate the effects of HIPEC on colonic anastomosis wound healing in a rat model.
  • To evaluate the influence of HIPEC timing (pre- vs. post-anastomosis) on healing outcomes.

Main Methods:

  • Thirty-six rats underwent colonic anastomosis and were randomized into control, pre-HIPEC, and post-HIPEC groups.
  • Hyperthermic intraperitoneal chemoperfusion utilized mitomycin C (20 mg/m²).
  • Outcomes assessed included bursting pressure, collagen deposits, inflammation, and foreign body reactions at 4 and 10 days.

Main Results:

  • Both HIPEC groups exhibited significantly lower bursting pressure compared to the control group.
  • Reduced collagen deposition was observed in HIPEC groups, correlating with lower bursting pressure.
  • No significant difference in healing impairment was noted between pre- and post-anastomosis HIPEC.

Conclusions:

  • HIPEC significantly impairs wound healing in colonic anastomosis in a rat model.
  • The timing of HIPEC relative to anastomosis does not alter the negative impact on healing.
  • Findings suggest careful consideration of HIPEC in patients with colonic anastomosis.
