To Assess the Effect of Intraperitoneal Cut Suture Ends in Pediatric Minimally Invasive Surgery - A Study in Wistar...

Area of Science:

• Surgical Innovation
• Minimally Invasive Surgery
• Biomaterials Science

Background:

• Advanced minimal access surgery requires extensive intracorporeal suturing.
• Cut suture ends left in the operative field increase surgical time.
• Safe methods for managing suture ends are needed to improve efficiency.

Purpose of the Study:

• To assess the effect of intraperitoneal cut suture ends in pediatric minimally invasive surgery.
• To evaluate the inflammatory reaction and adhesion formation caused by different suture materials left in the peritoneal cavity.
• To determine if leaving suture ends behind is safe and can save time in laparoscopic procedures.

Main Methods:

• An experimental study in Wistar rats subjected to laparotomy.
• Three groups of rats received different suture materials (braided absorbable, braided nonabsorbable, nonbraided nonabsorbable) left intraperitoneally.
• Animals were observed for 4 weeks, and the degree of peritoneal inflammatory reaction and adhesions was assessed.

Main Results:

• No morbidity or mortality was observed in any group.
• A significantly higher rate of adhesions was found in the braided nonabsorbable suture group (polyester) compared to the other groups.
• No adhesions were observed with the nonbraided nonabsorbable suture material (polyamide).

Conclusions:

• Braided suture materials, particularly nonabsorbable ones, should preferably be removed from the peritoneal cavity to minimize adhesion formation.
• Non-braided suture ends can be safely left intraperitoneally, potentially saving time and effort in advanced laparoscopic surgeries.
• Further histological studies are recommended to quantify the inflammatory response and validate these findings.
