Endoscopic suturing for gastrointestinal conditions shows promise. Preliminary mucosal ablation or resection before suturing significantly improves tissue healing compared to simple apposition, suggesting a need for further human trials.

Area of Science:

  • Gastroenterology
  • Minimally Invasive Surgery
  • Surgical Innovation

Background:

  • Minimally invasive surgery has spurred the development of endoscopic suturing techniques for gastrointestinal (GI) conditions.
  • Current techniques primarily achieve simple apposition of GI mucosa, but long-term mucosal apposition efficacy is undetermined.
  • This study investigates if preliminary mucosal manipulation is necessary for effective endoscopic suturing.

Purpose of the Study:

  • To evaluate the necessity of preliminary mucosal manipulation in endoscopic suturing.
  • To compare the long-term mucosal apposition of different endoscopic suturing techniques.
  • To assess the impact of mucosal ablation or resection on tissue healing in endoscopic suturing.

Main Methods:

  • Seven dogs underwent laparotomy and gastrotomy for proximal gastric mucosa exposure.

  • Three suturing techniques were applied: simple mucosal apposition, electrosurgical mucosal ablation, and mucosal resection before closure.
  • Histological scoring of tissue healing was performed after 2 weeks.

    • Main Results:

    • Mucosal ablation before apposition significantly enhanced tissue healing compared to simple apposition.
    • Histologic scores for ablation (1.5) and resection (1.25) were similar and superior to simple apposition (0.9).
    • The difference in healing scores between techniques was statistically significant (p=0.02).

    Conclusions:

    • Endoscopic suturing presents a potential alternative for managing various GI conditions.
    • Incorporating tissue ablation or mucosal resection before apposition warrants consideration for evolving endoscopic techniques.
    • Further human studies are essential to confirm the safety and long-term efficacy of these modified approaches.
