A novel flexible stapling system enables transoral, full-thickness gastric wall resection for early gastric adenocarcinoma and gastrointestinal stromal tumors, overcoming previous endoscopic limitations.

Area of Science:

  • Gastroenterology
  • Surgical Innovation
  • Endoscopic Procedures

Background:

  • Traditional endoluminal resection is limited to superficial layers (lamina mucosa and submucosa) due to the lack of safe endoscopic methods for closing the deeper gastric wall layers.
  • Maintaining the integrity of the muscularis propria is crucial as current endoscopic techniques cannot reliably ensure gastric wall closure.

Observation:

  • A flexible stapling system, SurgAssist, allows transoral introduction into the stomach alongside a gastroscope.
  • This system facilitated full-thickness inverted resection of gastric wall tumors in two patients with early gastric adenocarcinoma, resecting approximately 4x4 cm sections.

Findings:

  • The study demonstrates the feasibility of transoral, full-thickness gastric wall resection using the SurgAssist stapling system.

Related Experiment Videos

  • Successful resection was achieved in two patients, with one requiring endoscopic hemostasis, and both experienced uneventful postoperative courses.

    • Implications:

    • This transoral surgical approach offers a new, minimally invasive option for treating early gastric adenocarcinoma and gastrointestinal stromal tumors.
    • It expands the possibilities for endoscopic treatment of gastric conditions requiring full-thickness wall resection.
