Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

2.3K
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

7.0K
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 II: Nasointestinal and Gastrostomy Feeding

1.9K
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 III: Video Capsule Endoscopy

1.4K
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,...

Enteral Nutrition I: Orogastric and Nasogastric Feeding

2.8K
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...

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:

    Summary

    Percutaneous endoscopic gastrostomy is a key operative endoscopy procedure for long-term enteral feeding. This article details its indications, contraindications, complications, and procedural steps for surgeons.

    Area of Science:

    • Gastroenterology
    • Surgical Endoscopy

    Background:

    • Percutaneous endoscopic gastrostomy (PEG) is a vital intervention in digestive system operative endoscopy.
    • It serves as the primary method for patients requiring prolonged enteral nutrition.
    • Understanding PEG procedures is crucial for managing patients needing nutritional support.

    Purpose of the Study:

    • To outline the primary indications for performing PEG.
    • To identify contraindications that preclude PEG.
    • To describe potential complications associated with PEG and detail its procedural stages.

    Main Methods:

    • Review of established percutaneous endoscopic gastrostomy techniques.
    • Analysis of clinical data regarding PEG indications, contraindications, and outcomes.

  • Description of the step-by-step surgical process for PEG insertion.

    • Main Results:

    • Key indications for PEG include dysphagia and upper gastrointestinal obstruction.
    • Contraindications involve severe coagulopathy and upper GI tract anatomical abnormalities.
    • Common complications include site infection, dislodgement, and peritonitis.

    Conclusions:

    • Percutaneous endoscopic gastrostomy is an effective and essential procedure for enteral feeding.
    • Comprehensive knowledge of indications, contraindications, and potential complications is vital for safe application.
    • This guide aims to support both novice and experienced surgeon-endoscopists in performing PEG.
