Non-exposed endoscopic wall-inversion surgery (NEWS) offers a novel approach to gastric tumor resection. This technique aims to minimize contamination and tumor seeding during full-thickness resection, showing promising initial results in a small patient cohort.

Area of Science:

  • Gastroenterology
  • Surgical Innovation
  • Oncology

Background:

  • Gastric full-thickness resection traditionally risks intra-abdominal contamination and tumor seeding due to iatrogenic perforation.
  • Minimizing contamination and resected tissue volume is crucial for improving patient outcomes in gastric surgery.

Purpose of the Study:

  • To introduce and evaluate the preliminary outcomes of a novel surgical technique, non-exposed endoscopic wall-inversion surgery (NEWS).
  • To assess the feasibility, safety, and efficacy of NEWS in patients with gastric sub-mucosal tumors (SMT).

Main Methods:

  • NEWS involves marking the tumor, submucosal injection, laparoscopic seromuscular dissection with closure, and endoscopic mucosubmucosal incision.
  • Specimen retrieval is performed perorally.

  • A clinical observation cohort study was conducted on six patients undergoing NEWS for gastric SMT.

    • Main Results:

    • Initial attempts in three patients experienced perforation due to technical challenges.
    • After device modification, the procedure was successfully completed in the subsequent three patients.
    • No complications were observed in any of the six cases, demonstrating a safe learning curve.

    Conclusions:

    • NEWS facilitates en bloc full-thickness gastric resection.
    • The technique theoretically avoids peritoneal contamination and tumor dissemination.
    • NEWS presents a promising alternative for gastric tumor resection, potentially improving safety and reducing complications.
