Summary
Capsule retention after small-bowel video capsule endoscopy is rare. Double-balloon endoscopy (DBE) effectively retrieves retained capsules, potentially avoiding surgery and aiding diagnosis.
Area of Science:
- Gastroenterology
- Endoscopy
- Surgical Procedures
Background:
- Capsule retention is a known complication of small-bowel video capsule endoscopy.
- Surgery is the traditional method for capsule retrieval.
Purpose of the Study:
- Determine the incidence and causes of capsule retention.
- Evaluate double-balloon endoscopy (DBE) as a primary retrieval technique.
Main Methods:
- Retrospective analysis of 904 patients undergoing small-bowel video capsule endoscopy.
- Evaluation of DBE as the initial method for retrieving entrapped capsules.
Main Results:
- Capsule retention occurred in 0.88% of patients, causing obstruction in 6.
- All retained capsules were successfully retrieved using DBE.
- Five patients required elective surgery for underlying causes; one needed emergency surgery for perforations.
Conclusions:
- Capsule retention incidence is low.
- DBE is a reliable method for capsule removal, potentially preventing surgery.
- Preoperative retrieval via DBE facilitates diagnosis, staging, and surgical planning.

01:28Endoscopic 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...
01:26Endoscopic 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...

01:26Endoscopic Procedures V: ERCP
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.

01:25Endoscopic 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:
01:29Endoscopic 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:

Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
