Upper GI Series: Barium Swallow01:24

Upper GI Series: Barium Swallow

287
The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.
Purpose and Procedure
Patients undergoing this procedure ingest a liquid containing barium sulfate with a chalky...

Lower GI Series: Barium Enema

264
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...

Endoscopic Procedures I: Esophagogastroduodenoscopy

114
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 Laproscopy

80
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 V: ERCP01:26

Endoscopic Procedures V: ERCP

210
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.

Summary
This summary is machine-generated.

Routine upper gastrointestinal (UGI) series imaging after bariatric surgery has limited value for detecting leaks. Imaging decisions should be guided by clinical signs, not routine protocols, especially after gastric bypass.

Area of Science:

  • Bariatric Surgery
  • Gastrointestinal Imaging
  • Surgical Complications

Background:

  • Post-operative upper gastrointestinal (UGI) series are sometimes used to detect complications after bariatric procedures.
  • The utility of routine UGI imaging in the immediate post-operative period requires further investigation.

Purpose of the Study:

  • To evaluate the usage and diagnostic value of routine upper gastrointestinal (UGI) series for detecting leaks and other complications following bariatric surgery.
  • To identify factors influencing the decision to perform routine post-operative UGI imaging.

Main Methods:

  • Retrospective review of patients who underwent bariatric procedures (gastric bypass or sleeve gastrectomy) between 2008 and 2012.
  • Analysis of routine UGI series findings, complications, and patient demographics.

Main Results:

  • 135 patients (23%) received routine UGI imaging; 127 post-gastric bypass and 8 post-sleeve gastrectomy.
  • UGI series identified only 1 definite leak in gastric bypass patients; no leaks were found in sleeve gastrectomy patients or in the 77% who did not undergo imaging.
  • Sensitivity for leak detection was 100% but positive predictive value was only 20% in gastric bypass patients. Sleeve gastrectomy and male gender decreased likelihood of routine UGI.

Conclusions:

  • Routine UGI series imaging has limited value for detecting anastomotic leaks after gastric bypass and sleeve gastrectomy.
  • Post-operative imaging should be based on clinical parameters rather than routine protocols.
  • Gastric bypass and female gender were associated with increased likelihood of routine UGI imaging; further research is warranted.
