Thoracoscopy, surgical; with esophagomyotomy (Heller type)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Thoracoscopy, surgical; with esophagomyotomy (Heller type) is a minimally invasive surgical procedure that involves the use of a thoracoscope, which is a specialized instrument equipped with a camera and light source. This procedure is specifically designed to treat conditions affecting the esophagus, particularly those related to esophageal motility disorders. The term "esophagomyotomy" refers to the surgical incision made in the muscular layer of the esophagus to alleviate symptoms associated with conditions such as achalasia, where the esophagus has difficulty moving food into the stomach. The procedure is performed through small incisions in the chest wall, allowing for a direct view of the esophagus while minimizing trauma to surrounding tissues. The use of video-assisted thoracoscopic surgery (VATS) enhances the surgeon's ability to visualize the surgical field, leading to improved precision and potentially quicker recovery times for patients. The approach typically involves creating an artificial pneumothorax to facilitate access to the esophagus, followed by careful dissection and incision of the esophageal muscle, which is crucial for relieving the obstruction and restoring normal function.

1. Indications

Esophagomyotomy (Heller type) is indicated for patients suffering from specific esophageal motility disorders. The primary conditions for which this procedure is performed include:

  • Achalasia - A condition characterized by the inability of the lower esophageal sphincter to relax, leading to difficulty in swallowing and food obstruction.
  • Esophageal spasm - A disorder that causes intermittent contractions of the esophagus, resulting in chest pain and swallowing difficulties.
  • Other motility disorders - Conditions that affect the normal movement of the esophagus, causing symptoms such as dysphagia (difficulty swallowing) and regurgitation.

2. Procedure

The procedure for thoracoscopy with esophagomyotomy involves several critical steps to ensure successful surgical intervention. The following outlines the procedural steps:

  • Step 1: Incision and Access - A small posterolateral incision is made between the ribs, typically at the fourth, fifth, or sixth intercostal space, near the posterior aspect of the axillary line. This incision allows for the introduction of the videothoracoscope, providing the surgeon with a visual perspective of the esophagus from above.
  • Step 2: Additional Portal Incisions - Two additional portal incisions are created, one anterior and one posterior to the esophagus, to facilitate the introduction of surgical instruments necessary for the procedure.
  • Step 3: Lung and Diaphragm Retraction - Further portal incisions are made, and retractors are inserted to retract the lung and diaphragm, thereby providing better access to the pleural space and the esophagus.
  • Step 4: Creation of Pneumothorax - The pleural space is entered, and air is injected to create an artificial pneumothorax, which collapses the lung and enhances visibility and access to the surgical site.
  • Step 5: Identification and Retraction of the Esophagus - The distal esophagus is identified and retracted using a flexible esophagoscope, allowing for precise manipulation during the incision process.
  • Step 6: Incision of the Esophageal Muscular Layer - The muscular layer of the esophagus is incised longitudinally down to the submucosa using endoscopic scissors or hook cautery. This incision is extended approximately 0.5 cm into the stomach to ensure adequate relief of the obstruction.
  • Step 7: Placement of Chest Tube - Following the completion of the esophagomyotomy, a chest tube is placed through one of the existing portal incisions to facilitate drainage and prevent complications.
  • Step 8: Lung Re-expansion and Closure - The lung is re-expanded, and the portal incisions are closed. A nasogastric tube is then placed to assist with postoperative care and management.

3. Post-Procedure

After the thoracoscopy with esophagomyotomy, patients typically require monitoring for any complications related to the procedure. Expected recovery includes management of pain, monitoring for signs of infection, and ensuring proper function of the esophagus. The placement of a nasogastric tube aids in the initial postoperative feeding protocol, allowing for gradual reintroduction of oral intake as tolerated. Patients may also be advised on activity restrictions and follow-up appointments to assess healing and the effectiveness of the procedure.

53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
