[Laparoscopy versus laparotomy. An animal experiment study comparing adhesion formation in the dog]

Area of Science:

• Veterinary Surgery
• Surgical Complications
• Abdominal Adhesions

Background:

• Abdominal adhesions are a common complication following surgical procedures.
• Adhesions can lead to significant morbidity, including intestinal obstruction and chronic pain.
• Minimizing adhesion formation is a key goal in surgical innovation.

Purpose of the Study:

• To compare the incidence and severity of postoperative adhesions after laparoscopic versus open abdominal surgery in dogs.
• To evaluate the impact of surgical approach on adhesion formation following specific abdominal procedures.

Main Methods:

• Seven dogs underwent laparoscopic procedures and seven underwent open laparotomy for abdominal exploration, cecal resection, abdominal wall deserosation, and omentum resection.
• Postoperative adhesions were quantified using computer-aided measurement 8 days after surgery.

Main Results:

• Laparoscopic surgery led to significantly fewer adhesions compared to open laparotomy (P < 0.001).
• Open surgery resulted in extensive adhesions, including abdominal incision adhesions and interenteric adhesions.
• Identical surgical manipulations (cecal resection, deserosation) produced similar adhesion patterns regardless of the approach, indicating the approach itself influences adhesion formation.

Conclusions:

• The laparoscopic approach is associated with a significant reduction in postoperative abdominal adhesions in dogs.
• Laparoscopic surgery may offer a reduced risk of adhesion-related complications compared to conventional open surgery.
• Further research into laparoscopic techniques can help mitigate surgical complications in veterinary medicine.
