Esophagoscopy, flexible, transoral; with placement of endoscopic stent (includes pre- and post-dilation and guide wire passage, when performed)
CPT4 code
Name of the Procedure:
Esophagoscopy, flexible, transoral; with placement of endoscopic stent (includes pre- and post-dilation and guide wire passage, when performed)
Summary
An esophagoscopy is a procedure where a flexible tube with a camera (endoscope) is inserted through the mouth to examine the esophagus. During this specific procedure, an endoscopic stent is also placed to keep the esophagus open, which can include dilation (stretching) of the esophagus and the use of a guide wire.
Purpose
This procedure is used to address conditions that cause narrowing or blockage of the esophagus, such as strictures, tumors, or scar tissue. The goal is to improve swallowing and ensure the esophagus remains open for food and liquid passage.
Indications
Conditions that may warrant this procedure include esophageal cancer, benign strictures, achalasia, and esophageal injuries. Patients experiencing difficulty swallowing (dysphagia), frequent choking, or significant weight loss due to esophageal blockage may be candidates.
Preparation
Patients may need to fast for several hours before the procedure. They should inform their healthcare provider about any medications they are taking, especially blood thinners. Pre-procedure diagnostics may include barium swallow X-rays, upper GI series, or esophageal manometry.
Procedure Description
- The patient is typically given a sedative or anesthesia.
- The endoscope is introduced through the mouth and gently guided down the esophagus.
- The esophagus is examined visually.
- If necessary, the esophagus is dilated using a balloon or other dilators.
- A guide wire is placed to help position the stent.
- The stent is introduced and positioned across the narrowed or blocked area.
- Post-stent placement, the endoscope is removed.
Duration
The procedure typically takes about 30 minutes to 1 hour.
Setting
The procedure is performed in a hospital's endoscopy suite or an outpatient surgical center.
Personnel
A gastroenterologist or a specialized surgeon typically performs the procedure, assisted by nurses and possibly an anesthesiologist.
Risks and Complications
Common risks include sore throat, minor bleeding, and temporary swallowing difficulties. Rare but more serious risks include perforation of the esophagus, infection, severe bleeding, and stent migration.
Benefits
The primary benefit is the immediate improvement in swallowing and passage of food and liquids. Depending on the condition treated, benefits are usually noticed right after recovery from anesthesia.
Recovery
Post-procedure care includes monitoring for a few hours for any immediate complications. Patients may need to follow a soft diet initially and avoid strenuous activities. Follow-up appointments are essential to monitor stent position and esophagus healing.
Alternatives
Alternative treatments may include surgical interventions, dilation without stenting, or medication management. Each alternative has its pros and cons, like surgical risks or less immediate relief from symptoms.
Patient Experience
During the procedure, the patient will be under sedation or anesthesia, so discomfort is minimized. Post-procedure, a sore throat and minor discomfort can be expected, but pain management is provided. Recovery is relatively quick, with most patients resuming normal activities within a few days.
