Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

89
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:

Lower GI Series: Barium Enema01:23

Lower GI Series: Barium Enema

255
A Barium Enema, or a lower GI series, is a specialized radiographic examination designed to visualize the lower gastrointestinal tract, specifically the colon and rectum. This procedure is instrumental in diagnosing various conditions such as colorectal cancer, polyps, diverticulosis, and inflammatory bowel disease.
Procedure Details
The examination begins by inserting a lubricated rectal tube into the patient's rectum to administer a radiopaque barium solution. The barium flow is carefully...

Enteral Nutrition I: Orogastric and Nasogastric Feeding01:26

Enteral Nutrition I: Orogastric and Nasogastric Feeding

254
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...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

77
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...

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy01:26

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

80
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

202
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,...

Area of Science:

  • Pediatric Surgery
  • Colorectal Surgery
  • Defecation Disorders Management

Background:

  • Antegrade colonic enemas (ACE) are an effective treatment for defecation disorders, improving patient quality of life.
  • Current best practices for ACE channel placement, including type, age, and diagnosis, lack standardization.
  • Understanding practice patterns is crucial for optimizing ACE procedures.

Purpose of the Study:

  • To describe current practice patterns and patient characteristics related to antegrade colonic enema (ACE) channel placement.
  • To identify variations in ACE channel type and age at placement across institutions.
  • To analyze the influence of underlying diagnoses on ACE channel selection.

Main Methods:

  • Multicenter retrospective study of 500 children with ACE channels from 2017-2022.
  • Data collected from sites participating in the Pediatric Colorectal and Pelvic Learning Consortium (PCPLC).
  • Kruskal-Wallis test used to analyze variations in age at surgery by site.

Main Results:

  • Significant variation in median age at ACE channel placement across institutions (p=0.009).
  • Malone appendicostomy (74.2%) was the most common channel type, followed by cecostomy (23.2%).
  • Anorectal malformation was the primary indication for Malone and Neo-Malone appendicostomies, while idiopathic constipation predominated for cecostomy.

Conclusions:

  • Practice patterns for ACE channel placement exhibit significant institutional variation.
  • Age at placement and channel type differ across specialty pediatric colorectal centers.
  • Further research focusing on diagnosis- and age-specific outcomes is necessary to refine ACE recommendations.
