Endoscopic Procedures II: Colonoscopy

Endoscopic Procedures II: Colonoscopy

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Area of Science:

Veterinary Medicine
Equine Physiology

Background:

Cecal cannulation is crucial for nutritional and digestive physiology research in horses.
Existing techniques pose risks such as peritonitis and are technically demanding.

Purpose of the Study:

To describe a novel, two-stage technique for permanent cecal cannulation in standing horses.
To evaluate the safety and efficacy of this new cannulation method.

Main Methods:

A two-stage surgical procedure involving laparotomy, exteriorization of the cecal base, and subsequent cannula insertion.
Ten horses underwent the cannulation procedure.

Main Results:

One horse experienced cecal rupture after the first stage; two others had mild transient colic.
Four of nine horses experienced transient colic after cannula insertion, resolving within 24 hours.
Complete healing of the cannula site occurred in approximately 30 days.

Conclusions:

The described two-stage technique offers a safer and technically simpler alternative for permanent cecal cannulation in horses.
This method reduces the risk of peritonitis associated with intestinal leakage.
