Insights

Anal endosonography (AES) reveals distinct features of the anal canal in children. This imaging technique is valuable for assessing anal anatomy in healthy children and evaluating surgical outcomes in those with anorectal malformations.

Area of Science:

  • Pediatric imaging
  • Gastroenterology
  • Surgical anatomy

Background:

  • Congenital anorectal malformations require precise surgical correction.
  • Accurate anatomical assessment is crucial for successful outcomes.
  • Endosonography offers detailed visualization of pelvic floor structures.

Purpose of the Study:

  • To characterize the endosonographic features of the anal canal in healthy children.
  • To compare these findings with those in children with congenital anorectal malformations.
  • To assess the utility of anal endosonography (AES) in evaluating post-surgical anal anatomy.

Main Methods:

  • Anal endosonography (AES) was performed on two groups of children.
  • Group 1: 30 healthy controls.
  • Group 2: 15 children with congenital anorectal malformations.

Main Results:

  • Sphincter elements were clearly visualized in normal children.
  • The intersphincteric plane showed a characteristic double image in children.
  • AES accurately identified neoanus placement in 13 of 15 post-anorectoplasty patients.

Conclusions:

  • This study provides detailed endosonographic descriptions of the pediatric anal canal.
  • AES is a useful tool for anatomical assessment in children, particularly after anorectoplasty for anorectal malformations.

Endoscopic Procedures I: Esophagogastroduodenoscopy

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 Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

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 III: Video Capsule Endoscopy

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, unexplained...

Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...
Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

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:
