Feeding management before gastrointestinal studies in pigs

Area of Science:

• Veterinary Medicine
• Gastroenterology
• Surgical Research

Background:

• Pigs are valuable models for human gastrointestinal (GI) studies due to physiological and behavioral similarities.
• A clean and motile small intestine is crucial for porcine surgical models, especially for testing tethered ultrasound capsule endoscopes (USCE).
• Existing GI preparation protocols for pigs lack detailed administration, efficacy, and side effect information.

Purpose of the Study:

• To detail a method for preparing the porcine GI tract for surgery and USCE.
• To evaluate the efficacy and safety of a high-energy liquid diet for porcine GI preparation.
• To establish a reliable protocol for achieving a clean, motile small intestine in pigs.

Main Methods:

• Eleven female pigs were administered a high-energy liquid diet prior to surgery and USCE.
• The diet's acceptance, ease of administration, and impact on intestinal cleanliness and motility were assessed.
• Physiological and behavioral parameters were monitored for any abnormalities.

Main Results:

• The high-energy liquid diet was readily accepted and easily administered to the pigs.
• The diet successfully produced a clean and motile small intestine in all subjects.
• No detectable physiological or behavioral abnormalities were observed in the pigs post-administration.

Conclusions:

• A high-energy liquid diet is an effective and safe method for porcine gastrointestinal tract preparation.
• This dietary regimen supports the use of pigs as reliable models for human GI studies and capsule endoscope testing.
• The detailed protocol provides valuable technical information for future research involving porcine GI models.
