Sutured laparoscopic cholecystojejunostomy evolved in an animal model

Area of Science:

• Veterinary Surgery
• Surgical Innovation
• Gastrointestinal Surgery

Background:

• Surgical anastomoses, particularly bilioenteric reconstructions, require reliable techniques for optimal healing and function.
• Existing suturing methods can be time-consuming and may lead to complications like adhesions.
• Improved surgical tools and techniques are crucial for enhancing patient outcomes in veterinary and human medicine.

Purpose of the Study:

• To develop and evaluate a novel, efficient knotting technique for initiating and terminating suture lines.
• To introduce and assess a specially designed curved needle ('Endoski' needle) for improved tissue passage during anastomosis.
• To assess the efficacy and healing of cholecystojejunal anastomoses constructed using these new techniques in a porcine model.

Main Methods:

• Acute and chronic surgical experiments were performed on young pigs over a 2-year period.
• A new quick knotting technique and a curved 'Endoski' needle were utilized.
• Cholecystojejunal anastomoses were created using a semi-closed technique with a single layer of continuous polyglactin sutures.

Main Results:

• The developed knotting technique and needle facilitated the construction of surgical anastomoses.
• Chronic experiments demonstrated patent and well-healed bilioenteric anastomoses capable of satisfactory bile conveyance after common bile duct ligation.
• A notable finding was the virtual absence of adhesions around the anastomoses in the chronic experimental group.

Conclusions:

• The novel knotting technique and curved needle offer an efficient method for creating surgical anastomoses.
• These techniques promote excellent healing and patency in bilioenteric reconstructions, as evidenced by successful bile flow and minimal adhesions.
• The findings suggest a potential for improved outcomes in surgical procedures requiring bilioenteric anastomosis.
