Summary

This study shows laparoscopic transgastric suturing is a feasible method for controlling bleeding peptic ulcers in pigs. The technique, using sclerosing agents and sutures, shows promise for future human applications in gastrointestinal surgery.

Area of Science:

  • Minimally Invasive Surgery
  • Gastroenterology
  • Surgical Innovation

Background:

  • Peptic ulcers frequently cause upper gastrointestinal bleeding.
  • Endoscopic treatments for bleeding ulcers can be unsuccessful.
  • A novel laparoscopic approach was investigated for controlling ulcer bleeding.

Purpose of the Study:

  • To assess the feasibility of a laparoscopic transgastric technique for controlling bleeding peptic ulcers.
  • To evaluate the efficacy of transgastric suturing in a porcine model.
  • To explore potential applications in human surgery.

Main Methods:

  • Twenty pigs underwent creation of posterior gastric ulcers using a "lift and cut technique."
  • Bleeding ulcers were treated with sclerosing agents (epinephrine and ethanolamine oleate).

  • Intraluminal suturing with 2-0 silk and intracorporeal knots was performed laparoscopically.

    • Main Results:

    • Gastric ulcers averaged 7 mm in diameter and extended into the vascular submucosa.
    • Significant bleeding (2 cm³/min) occurred in 40% of ulcers.
    • Sclerotherapy and intraluminal sutures successfully controlled bleeding in 95% of cases, with technical feasibility in 80%.

    Conclusions:

    • Laparoscopic transgastric suturing, combined with sclerotherapy, effectively controls bleeding peptic ulcers.
    • This technique demonstrates promise for future human application in managing gastrointestinal bleeding.
    • Developed intragastric suturing skills may benefit other surgical procedures.
