Abstract

Insights

The fluoroscopy-guided "Loop method" safely and effectively removes migrated esophageal stents (MES) in 100% of cases. This technique offers a viable alternative for stent removal, with no major complications observed.

Area of Science:

  • Gastroenterology
  • Interventional Endoscopy
  • Medical Imaging

Background:

  • Migrated esophageal stents (MES) pose a clinical challenge, necessitating safe and effective removal techniques.
  • Esophageal stenting is a common procedure for managing dysphagia, but stent migration can occur.

Purpose of the Study:

  • To evaluate the efficacy and safety of a novel fluoroscopy-guided

Main Methods:

  • A retrospective study analyzed 25 patients who underwent migrated esophageal stent removal using the "loop method" under fluoroscopy.
  • Primary outcomes included technical success and complications; secondary outcomes assessed procedure time, radiation exposure, and biochemical markers (WBC, Hb, PLT, ALB, ALT, TB, UN, CRP) pre- and post-procedure.

Main Results:

  • The "loop method" achieved 100% technical success with no major complications.
  • Mean procedure time was 39.44 minutes and mean radiation exposure was 332.88 mGy, with no significant differences between benign and malignant cases.
  • Significant improvements were observed in hemoglobin and albumin levels post-procedure, while other biochemical markers remained largely unchanged.

Conclusions:

  • Fluoroscopy-guided "Loop method" is an effective and safe technique for migrated esophageal stent removal.
  • This method presents a valuable alternative for managing migrated esophageal stents, demonstrating high success rates and a favorable safety profile.

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 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,...

Endoscopic 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.

Esophageal Strictures-II: Clinical Features and Management

Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

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...
