Summary
Enteral feeding stimulates gallbladder contraction, but the effect diminishes as the feeding tube is placed deeper in the intestine. This study evaluated gallbladder motility in dogs receiving Lipofundin via different feeding tube positions.
Area of Science:
- Gastroenterology
- Veterinary Medicine
- Physiology
Background:
- Gallbladder motility during enteral feeding is not well understood.
- Nutritional support is crucial for critically ill patients.
Purpose of the Study:
- To investigate the effect of enteral feeding on gallbladder function in dogs.
- To assess gallbladder contraction in response to Lipofundin infusion at various intestinal locations.
Main Methods:
- Five healthy Beagle dogs were used.
- Lipofundin infusion was administered via feeding tube into the jejunum, duodenojejunal junction, descending duodenum, and stomach.
- Gallbladder volume (GBV) was monitored using ultrasonography.
Main Results:
- Lipofundin infusion induced gallbladder contraction, with maximal contraction observed at 9.2% in the jejunum, 16.5% at the duodenojejunal junction, and 26.3% in the descending duodenum.
- Oral administration of the cholagogue meal resulted in a mean maximal gallbladder contraction of 33.8%.
- Deeper placement of the feeding tube led to reduced and shorter gallbladder contractions.
Conclusions:
- Ultrasound-guided gallbladder emptying is effective for monitoring cholagogue effects.
- The efficacy of enteral feeding in stimulating gallbladder contraction is dependent on the feeding tube's anatomical position.
- Findings suggest that the location of enteral feeding influences gallbladder response.

01:15Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

01:26Enteral Nutrition I: Orogastric and Nasogastric Feeding
Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.

01:20Cholecystitis
Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...
01:17Gallbladder
The gallbladder is a small, pear-shaped organ that plays a crucial role in our digestive system. Measuring about 10 cm in length, it is comparable in size to a kiwi fruit and is located in a hollow area on the lower surface of the liver. The gallbladder's primary function is to store and concentrate bile, a fluid produced by the liver that aids in digestion.
The gallbladder's anatomy consists of three regions: the fundus, body, and neck. Extending from the neck, the cystic duct joins the common...

01:26Endoscopic Procedures V: ERCP
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

01:25Acute Pancreatitis I: Introduction
Acute pancreatitis is the sudden inflammation of the pancreas caused by the early activation of digestive enzymes, leading to the autodigestion of pancreatic tissue. This results in local inflammation and, in severe cases, systemic complications.EtiologyUnderstanding the underlying causes is crucial, as identifying the etiology guides treatment and anticipates complications. Acute pancreatitis can be triggered by various factors, typically grouped into the following clinical categories.Biliary...
