Laparoscopy, surgical, esophagomyotomy (Heller type), with fundoplasty, when performed

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A laparoscopic Heller-type esophagomyotomy is a surgical procedure designed to alleviate symptoms associated with esophageal conditions, particularly achalasia. This minimally invasive technique involves the division of the muscle fibers at the lower esophageal sphincter to facilitate easier passage of food from the esophagus into the stomach. The procedure is performed using a laparoscope, which is a thin, lighted tube inserted through small incisions in the abdomen. The term "fundoplasty" refers to the surgical technique that may be performed in conjunction with the esophagomyotomy to reinforce the lower esophageal sphincter and prevent reflux. During the procedure, pneumoperitoneum is established, allowing the surgeon to visualize the abdominal cavity clearly. Multiple laparoscopic ports are inserted to provide access for surgical instruments. The surgical team inspects the stomach and esophagus, identifies critical anatomical structures, and performs necessary dissections to ensure a successful outcome. The myotomy involves careful cutting of both longitudinal and circular muscle fibers to relieve pressure at the esophagogastric junction, while the fundoplasty, if indicated, involves suturing the gastric fundus to the diaphragm to enhance the effectiveness of the myotomy and reduce the risk of postoperative complications.

1. Indications

The laparoscopic Heller-type esophagomyotomy with fundoplasty is indicated for patients suffering from specific esophageal conditions that impede normal swallowing and cause significant discomfort. The primary indications include:

  • Achalasia A condition characterized by the inability of the lower esophageal sphincter to relax, leading to difficulty in swallowing and food retention in the esophagus.
  • Esophageal dysmotility Disorders that affect the coordinated muscle contractions of the esophagus, resulting in swallowing difficulties.
  • Severe gastroesophageal reflux disease (GERD) When associated with achalasia, where the esophagus fails to function properly, leading to reflux symptoms.

2. Procedure

The laparoscopic Heller-type esophagomyotomy with fundoplasty involves several critical procedural steps, which are detailed as follows:

  • Step 1: Establishing pneumoperitoneum The procedure begins with the establishment of pneumoperitoneum, which is the introduction of carbon dioxide gas into the abdominal cavity to create a working space for the laparoscopic instruments. This is typically achieved through a Veress needle or a trocar.
  • Step 2: Insertion of laparoscopic ports Following pneumoperitoneum, four to five laparoscopic ports are inserted into the upper abdomen. These ports allow for the introduction of the laparoscope and other surgical instruments necessary for the procedure.
  • Step 3: Inspection of the stomach and esophagus The laparoscope is inserted through one of the ports, enabling the surgical team to visually inspect the stomach and esophagus for any abnormalities or complications.
  • Step 4: Dissection of the gastric fundus The gastric fundus is grasped and pulled down to expose the area. Short gastric vessels are divided to facilitate further dissection. The phrenoesophageal ligament is cut to enhance visibility of the anterior gastric cardia and distal esophagus.
  • Step 5: Dissection of the esophagogastric junction The area behind the esophagogastric junction is carefully dissected, and a drain may be placed as needed. The vagus nerves are identified and protected throughout the procedure to prevent complications.
  • Step 6: Identification of the squamocolumnar junction An endoscope is utilized to identify the squamocolumnar junction, which is crucial for the subsequent myotomy.
  • Step 7: Performing the myotomy Traction is applied at the esophagogastric junction, and the gastric cardia is incised longitudinally, starting just distal to the squamocolumnar junction and extending approximately 6-8 cm into the esophageal muscle. Both longitudinal and circular muscle fibers are divided to expose the submucosa.
  • Step 8: Insufflation and inspection The stomach is insufflated through the endoscope, and the incision is inspected to ensure that all muscle fibers along the entire length of the incision have been adequately divided. Any remaining muscle fibers are cut to ensure complete myotomy.
  • Step 9: Manometry catheter placement A manometry catheter is placed in the stomach to obtain pressure recordings, which help assess the effectiveness of the myotomy.
  • Step 10: Final inspection and fundoplasty Areas of positive pressure along the incision site are inspected again, and any intact muscle fibers are divided. Following the completion of the myotomy, a fundoplasty is performed as needed. For a Dor anterior fundoplasty, the fundus is folded over the abdominal side of the myotomy and sutured to the crural diaphragm to reinforce the lower esophageal sphincter.

3. Post-Procedure

Post-procedure care following a laparoscopic Heller-type esophagomyotomy with fundoplasty typically involves monitoring the patient for any complications, managing pain, and ensuring proper recovery. Patients may be advised to follow a specific diet, starting with clear liquids and gradually progressing to solid foods as tolerated. Follow-up appointments are essential to assess the surgical site, evaluate the effectiveness of the procedure, and monitor for any signs of complications such as infection or reflux. The expected recovery time may vary, but many patients can return to normal activities within a few weeks, depending on their overall health and the complexity of the surgery.
