Endoscopic Procedures I: Esophagogastroduodenoscopy

1.8K
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 IV: Sigmoidoscopy and Laproscopy

974
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Endoscopic Procedures V: ERCP

5.1K
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

1.5K
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.
Nasointestinal Feeding
Nasointestinal feeding involves placing a tube...

Area of Science:

  • Gastroenterology
  • Minimally Invasive Surgery
  • Interventional Radiology

Background:

  • Standard gastrostomy tube placement (PEG, PIG) faces challenges in patients with complex medical histories, obesity, or altered anatomy.
  • An aging population and advancements in healthcare increase the prevalence of patients with comorbidities complicating feeding tube insertion.
  • Traditional endoscopic and radiologic gastrostomy techniques may become technically difficult or impossible in these complex cases.

Purpose of the Study:

  • To review first-line gastrostomy techniques.
  • To emphasize the utility and procedural technique of Laparoscopic-Assisted Percutaneous Endoscopic Gastrostomy (LAPEG) for challenging cases.
  • To provide an alternative option for long-term enteral nutrition when standard methods fail.

Main Methods:

  • Review of existing literature on gastrostomy techniques.
  • Emphasis on the combined approach of laparoscopy and percutaneous endoscopic gastrostomy (PEG).
  • Discussion of direct intraperitoneal visualization to ensure safe tube placement.

Main Results:

  • Laparoscopic-assisted PEG (LAPEG) provides direct visualization, ensuring a safe tract free from intervening structures.
  • LAPEG serves as a viable alternative when standard percutaneous endoscopic gastrostomy (PEG) or percutaneous image-guided gastrostomy (PIG) are not feasible.
  • This technique addresses challenges posed by obesity and complex patient anatomy.

Conclusions:

  • Laparoscopic-assisted PEG (LAPEG) is a valuable technique for gastrostomy tube placement in complex patient populations.
  • It enhances safety by providing direct visualization during the procedure.
  • LAPEG expands the options for providing essential enteral nutrition when standard methods are contraindicated or technically impossible.
