Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

1.5K
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.

Enteral Nutrition I: Orogastric and Nasogastric Feeding

2.3K
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...

Inflammatory Bowel Disease V: Surgical Management

830
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Area of Science:

  • Gastroenterology
  • Biomaterials Science
  • Medical Device Engineering

Background:

  • Enteral stents have evolved significantly in design and composition, leading to expanded clinical applications.
  • Initially used for palliative care in malignant diseases, their role has broadened to first-line treatments for various gastrointestinal (GI) disorders.
  • Indications now include endoscopic management of fistulas and leaks, in addition to restoring lumen patency.

Purpose of the Study:

  • To critically review recent literature on enteral stents.
  • To provide guidance for endoscopists in selecting appropriate stents for optimal patient management.
  • To highlight the expanding therapeutic landscape of gastrointestinal prostheses.

Main Methods:

  • Systematic review of recently published literature on enteral stents.
  • Analysis of different stent types, including self-expandable plastic and metal stents (uncovered, partially covered, fully covered), and biodegradable stents.
  • Evaluation of emerging technologies such as drug-eluting stents.

Main Results:

  • Diverse enteral stent designs (plastic, metal, biodegradable) offer tailored solutions for GI conditions.
  • Stents are effective in palliation, restoring patency, and managing complex issues like fistulas and leaks.
  • Drug-eluting stents are emerging as a dual-purpose option for palliative treatment and local chemotherapy.

Conclusions:

  • Enteral stents represent a rapidly advancing field with diverse applications in gastroenterology.
  • The choice of stent depends on specific clinical indications, patient factors, and desired outcomes.
  • Continued research and evaluation are crucial for optimizing the use of these prostheses in clinical practice.
