Area of Science:

  • Minimally invasive surgical techniques
  • Gastrointestinal endoscopy
  • Surgical oncology

Context:

  • Sessile polyps involving the whole circumference up to 8 cm present a surgical challenge.
  • Conventional surgical procedures for large polyps can lead to significant morbidity.
  • The development of advanced endoscopic and microsurgical tools is crucial for improving patient outcomes.

Purpose:

  • To evaluate the efficacy and safety of transanal endoscopic microsurgery (TEMS) for large, circumferential sessile polyps.
  • To introduce and assess the potential of endoscopic-microsurgical esophageal dissection.
  • To compare the outcomes of these minimally invasive techniques with conventional surgical methods.

Summary:

  • Transanal endoscopic microsurgery (TEMS) was successfully employed to resect sessile polyps up to 8 cm in circumference, with defects closed by endoscopic suture or anastomosis.

  • The study highlights lower complication and recurrence rates, shorter postoperative courses, and reduced pain compared to traditional procedures.
  • A novel endoscopic-microsurgical approach for esophageal dissection using an operating mediastinoscope demonstrated superiority over conventional methods in animal studies.

    • Impact:

    • TEMS provides a less invasive and more effective treatment option for challenging colorectal polyps.
    • Endoscopic-microsurgical esophageal dissection represents a significant advancement in minimally invasive thoracic surgery.
    • These techniques have the potential to reduce patient recovery time and improve overall surgical outcomes.
