Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding01:15

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

707
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.

Endoscopic Procedures I: Esophagogastroduodenoscopy

751
An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Endoscopic Procedures V: ERCP

2.3K
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.

Enteral Nutrition I: Orogastric and Nasogastric Feeding

1.1K
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.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

Hepatic Portal System01:21

Hepatic Portal System

4.9K
The hepatic portal system, a critical part of our circulatory framework, transports nutrient-laden, deoxygenated blood from the gastrointestinal tract and spleen to the liver. This ingenious system plays an indispensable role in maintaining our body's metabolic equilibrium.
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is...

Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

621
Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...

Area of Science:

  • Gastroenterology
  • Interventional Endoscopy
  • Biliary Interventions

Background:

  • Endoscopic retrograde cholangiopancreatography (ERCP) is standard for obstructive jaundice, but can fail due to anatomical challenges.
  • EUS-guided biliary drainage (BD) emerged as an alternative, facilitated by advancements in EUS technology.
  • Alternative BD methods include surgery and percutaneous transhepatic drainage.

Purpose of the Study:

  • To evaluate EUS-guided biliary drainage as a treatment for obstructive jaundice when ERCP is unsuccessful.
  • To detail the technical aspects and outcomes of EUS-guided hepaticogastrostomy.

Main Methods:

  • EUS-guided puncture and contrast injection of the left biliary tree.
  • Access via the gastric wall through hepatic segment III.
  • Diathermic tract dilation using a cystotome, followed by plastic or metallic stent placement.

Main Results:

  • Technical success rate for hepaticogastrostomy approaches 98%.
  • Complications occur in 15%-20% of cases, including pneumoperitoneum, bilioperitoneum, infection, and stent dysfunction.
  • Partially covered stents (70% covered) were used to mitigate bile leakage.

Conclusions:

  • EUS-guided biliary drainage is a highly successful alternative for obstructive jaundice when ERCP fails.
  • Experienced centers and teams familiar with ERCP can perform this procedure safely.
  • Careful technique and stent selection are crucial for managing complications.
