Anatomy of the Intestines01:23

Anatomy of the Intestines

87.5K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Small Intestine01:15

Small Intestine

4.0K
The small intestine is primarily responsible for digestion and nutrient absorption. It spans from the pyloric sphincter to the ileocecal valve and connects to the large intestine.
The small intestine is divided into three main sections - the duodenum, jejunum, and ileum. The duodenum, approximately 25 cm long, is nearest the stomach. It acts as a 'mixing bowl,' where chyme (partially digested food) blends with digestive enzymes from the pancreas and liver. The duodenum's unique...

Large Intestine01:09

Large Intestine

5.1K
The large intestine is divided into three main regions: the cecum, colon, and rectum. Extending from the ileocecal valve to the anus, it frames the small intestine on three sides.
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...

Endoscopic Studies II: Thoracocentesis01:26

Endoscopic Studies II: Thoracocentesis

1.5K
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

1.2K
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 II: Colonoscopy

755
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

Endoscopic full thickness biopsy (EFTB) offers a less invasive method for diagnosing gastrointestinal neuromuscular diseases. This technique provides adequate tissue samples, comparable to surgical biopsies, with a favorable safety profile.

Area of Science:

  • Gastroenterology
  • Surgical Innovation
  • Diagnostic Pathology

Background:

  • Accurate diagnosis of gastrointestinal neuromuscular diseases necessitates full thickness biopsy for comprehensive histologic evaluation.
  • Historically, surgical biopsies were the standard for obtaining adequate tissue samples.
  • Endoscopic techniques are evolving to provide less invasive diagnostic options.

Purpose of the Study:

  • To review the evolution of biopsy procedures for gastrointestinal neuromuscular diseases.
  • To present current techniques of endoscopic full thickness biopsy (EFTB).
  • To highlight EFTB's role in diagnosing gastrointestinal neuromuscular disorders.

Main Methods:

  • Review of advancements in endoscopic full thickness resection techniques.
  • Focus on clip-assisted close-then-cut EFTB.
  • Evaluation of early clinical experiences and safety profiles.

Main Results:

  • Endoscopic full thickness biopsy (EFTB) provides adequate full-thickness specimens, including the myenteric plexus and ganglia.
  • Clip-assisted EFTB demonstrates acceptable safety profiles in early clinical use.
  • Endoscopic methods show non-inferiority to surgical biopsies in terms of tissue adequacy.

Conclusions:

  • EFTB is a promising, less invasive approach for diagnosing gastrointestinal neuromuscular diseases.
  • It potentially decreases complication risks compared to surgical biopsies.
  • Further large prospective studies are required to confirm efficacy, safety, and patient outcomes.
