Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

171
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 I: Esophagogastroduodenoscopy

348
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 V: ERCP01:26

Endoscopic Procedures V: ERCP

898
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.

Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

184
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:

Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

329
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,...

Lower GI Series: Barium Enema01:23

Lower GI Series: Barium Enema

494
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...

Area of Science:

  • Gastroenterology
  • Endoscopy
  • Geriatric Medicine

Background:

  • Single-balloon enteroscopy (SBE) is a key tool for diagnosing and treating small bowel conditions, particularly obscure gastrointestinal bleeding and iron deficiency anemia.
  • The safety and efficacy of SBE in the elderly population, however, remain understudied.

Purpose of the Study:

  • To evaluate the safety and feasibility of both antegrade and retrograde SBE in elderly patients.
  • To compare diagnostic yield, therapeutic yield, and complication rates across different age groups.

Main Methods:

  • A retrospective cohort study analyzed 284 SBE procedures performed between March 2011 and May 2020.
  • Patients were categorized into three groups: under 65, 65-75, and over 75 years old.
  • Statistical analyses included ANOVA, chi-squared tests, and logistic regression to compare outcomes.

Main Results:

  • Elderly patients (over 75) showed a higher likelihood of GI bleeding as an indication for SBE.
  • Diagnostic yield (68.0%) and therapeutic intervention rates (58.5%) were significantly higher in the elderly group.
  • Angioectasias were the most common finding and were more prevalent in the elderly (44%).
  • Overall complication rates were low (0.9%) and comparable across all age groups.

Conclusions:

  • Single-balloon enteroscopy is a safe and feasible procedure for elderly patients.
  • SBE demonstrates superior diagnostic and therapeutic yields in older individuals, primarily due to a higher incidence of small bowel angioectasias.
