Official Description

Esophagogastric fundoplasty, with fundic patch (Thal-Nissen procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Esophagogastric fundoplasty, specifically the Thal-Nissen procedure, is a surgical intervention designed to address complications arising from a hiatal hernia and gastroesophageal reflux disease (GERD). This procedure aims to restore the normal anatomical position of the stomach and esophagus, thereby alleviating symptoms associated with reflux. The term "fundoplasty" refers to the surgical technique that involves the manipulation of the fundus, which is the upper part of the stomach, to create a barrier against the backflow of gastric contents into the esophagus. The procedure is performed using a transpleural approach, which involves accessing the esophagus through the pleural cavity, allowing for better visualization and mobilization of the esophagus and surrounding structures. The surgical steps include making incisions in the diaphragm and stomach, mobilizing the greater curvature of the stomach, and utilizing a split thickness skin graft to reinforce the fundus. The ultimate goal of the Thal-Nissen procedure is to create a functional valve mechanism at the esophagogastric junction, thereby reducing the incidence of reflux and improving the patient's quality of life.

1. Indications

The Thal-Nissen procedure is indicated for patients suffering from conditions that necessitate surgical intervention to correct anatomical and functional abnormalities of the esophagus and stomach. The following are the primary indications for this procedure:

  • Hiatal Hernia - A condition where a portion of the stomach protrudes through the diaphragm into the chest cavity, often leading to gastroesophageal reflux.
  • Gastroesophageal Reflux Disease (GERD) - A chronic condition characterized by the backflow of stomach contents into the esophagus, causing symptoms such as heartburn, regurgitation, and discomfort.

2. Procedure

The Thal-Nissen procedure involves several critical steps to effectively perform the fundoplasty. Each step is designed to ensure proper alignment and function of the esophagus and stomach.

  • Step 1: Mobilization of the Esophagus - The procedure begins with the mobilization of the esophagus using a transpleural approach, which allows the surgeon to access the esophagus through the pleural cavity for better visualization and manipulation.
  • Step 2: Diaphragmatic Incision - A radial incision is made through the diaphragm to expose the stomach, facilitating further surgical steps.
  • Step 3: Mobilization of the Greater Curvature - The greater curvature of the stomach is mobilized to allow for the necessary adjustments to be made during the procedure.
  • Step 4: Prolapse of the Fundus - The fundus of the stomach is allowed to prolapse into the chest cavity, which is a key aspect of the fundoplasty technique.
  • Step 5: Incision of the Esophagus - The lower aspect of the esophagus is incised longitudinally to the fundus of the stomach, which is crucial for widening the gastric inlet.
  • Step 6: Widening the Gastric Inlet - The edges of the incision are approximated transversely to widen the gastric inlet, enhancing the flow of food and reducing reflux.
  • Step 7: Harvesting the Skin Graft - A split thickness skin graft is harvested and tacked to the fundus of the stomach to provide additional support and reinforcement.
  • Step 8: Placement of the Dilator - A dilator is passed through the mouth into the esophagus and stomach to maintain the desired width of the lumen at the esophagogastric junction.
  • Step 9: Wrapping the Fundus - The fundus is wrapped around the esophagus and sutured to the right side of the esophagus, creating pressure distally to prevent gastroesophageal reflux.
  • Step 10: Placement of Anchoring Sutures - Anchoring sutures are placed from the esophagus to the fundus and then to the diaphragm to secure the new anatomical position.
  • Step 11: Reduction of the Fundus - The fundus is reduced through the diaphragm back into the abdominal cavity, and the anchoring sutures are tied to maintain stability.
  • Step 12: Closure of Incisions - Finally, the dilator is removed, chest tubes are placed as necessary, and the incisions are closed to complete the procedure.

3. Post-Procedure

After the Thal-Nissen procedure, patients typically require monitoring for any complications related to the surgery. Post-procedure care may include pain management, monitoring for signs of infection, and ensuring proper function of the esophagogastric junction. Patients may also need to follow specific dietary guidelines during the recovery period to facilitate healing and prevent complications. The expected recovery time can vary, but patients are generally advised to avoid strenuous activities for a period to allow for proper healing of the surgical site.

51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
