Summary

Trans-cervical endometrial resection (TCRE) causes minimal thermal effects and tissue damage. This gynecologic procedure provides excellent histological samples for analysis.

Area of Science:

  • Gynecologic surgery
  • Minimally invasive procedures
  • Surgical pathology

Background:

  • Transcervical endometrial resection (TCRE) is a common gynecologic procedure.
  • Understanding the acute thermal effects and tissue damage is crucial for patient safety and procedural optimization.

Purpose of the Study:

  • To evaluate the acute tissue effects, specifically temperature changes and depth of damage, during TCRE.
  • To assess the impact of different energy settings on these effects.

Main Methods:

  • Eight women undergoing hysterectomy had TCRE performed using an Iglesias resectoscope and 1.5% glycine irrigation.
  • Varying cutting currents (80/120 W) and coagulation settings (40/60 W) were applied.
  • Temperature measurements were taken at uterine vessels, ovarian ligaments, and the serosal surface.

Main Results:

  • A minimal temperature increase of 2.0°C at the serosal surface during coagulation and 0.3°C during resection was observed.
  • Maximum tissue damage depth was limited to 1.7 mm.
  • No significant temperature changes were detected at the uterine vessels or ovarian ligaments.

Conclusions:

  • TCRE demonstrates minimal thermal spread and tissue destruction, preserving tissue integrity for histological examination.
  • The procedure is safe with regard to adjacent structures like uterine vessels and ovarian ligaments.
  • Careful technique in cornual and isthmus regions is advised for optimal outcomes.
