Official Description

Partial esophagectomy, distal two-thirds, with thoracotomy and separate abdominal incision, with or without proximal gastrectomy; with colon interposition or small intestine reconstruction, including intestine mobilization, preparation, and anastomosis(es)

Common Language Description

The procedure described by CPT® Code 43118 is a complex surgical intervention known as a partial esophagectomy, specifically targeting the distal two-thirds of the esophagus. This procedure is performed through a thoracotomy, which involves making an incision in the chest, and a separate abdominal incision, allowing access to both the thoracic and abdominal cavities. The surgery may be conducted with or without a proximal gastrectomy, which is the partial removal of the stomach. A key aspect of this procedure is the reconstruction of the esophagus, which can be achieved using either a segment of the colon or small intestine. This involves mobilizing and preparing the chosen segment of intestine, followed by creating an anastomosis, or surgical connection, to either the pharynx or the remaining portion of the esophagus. The surgical approach typically includes a right posterior thoracotomy, where the skin is incised, and the incision is extended through the soft tissues to access the thoracic cavity. The procedure requires careful dissection to expose the esophagus while preserving critical structures such as the pneumogastric and recurrent nerves, as well as the azygous vein and bronchial artery. The esophagus is meticulously freed from surrounding tissues, and a separate incision in the abdomen allows for exploration of the peritoneal cavity and mobilization of the stomach. The esophagus is then transected near the esophagogastric junction, and if necessary, a portion of the stomach may also be excised to ensure complete removal of any malignancy. The choice of using a section of colon or small intestine for reconstruction depends on various factors, including the extent of the disease and the specific anatomy of the patient. The procedure is intricate, requiring precise measurements and careful handling of vascular structures to ensure adequate blood supply to the graft. Following the anastomosis, a jejunostomy tube is placed to facilitate feeding and decompression, highlighting the complexity and the need for meticulous surgical technique in this procedure.

1. Indications

The procedure described by CPT® Code 43118 is indicated for patients with conditions affecting the esophagus that may require surgical intervention. These indications include:

  • Malignancy of the Esophagus - The procedure is often performed to remove cancerous tumors located in the distal esophagus.
  • Severe Esophageal Strictures - Patients with significant narrowing of the esophagus that cannot be managed through less invasive means may require this surgery.
  • Benign Esophageal Tumors - Non-cancerous growths that obstruct the esophagus may necessitate surgical removal.
  • Esophageal Perforation - In cases where the esophagus has been perforated, surgical intervention is required to prevent further complications.

2. Procedure

The procedure involves several critical steps, each essential for the successful completion of the partial esophagectomy:

  • Step 1: Incision and Access - A right posterior thoracotomy is performed, beginning with an incision through the skin and extending through the soft tissues. The scapula is retracted to allow entry into the thoracic cavity without disrupting the pleura.
  • Step 2: Esophageal Exposure - Retropleural dissection is conducted to retract the lung and expose the esophagus. Key structures such as the pneumogastric and recurrent nerves, as well as the azygous vein and bronchial artery, are identified to avoid injury during the procedure.
  • Step 3: Esophageal Mobilization - The esophagus is carefully freed from surrounding tissues using both blunt and sharp dissection techniques, ensuring that it is adequately mobilized for removal.
  • Step 4: Abdominal Incision - A separate incision is made in the upper abdomen to explore the peritoneal cavity. The stomach is mobilized, and the diaphragmatic hiatus is split to access the lower posterior mediastinum and the esophagus.
  • Step 5: Transection of the Esophagus - The esophagus is transected near the esophagogastric junction. If necessary, a portion of the stomach may also be excised to ensure complete removal of malignancy.
  • Step 6: Graft Preparation - If a section of colon is used for reconstruction, the omentum is dissected off the colon. For a left colon interposition graft, the middle colic artery is ligated, and the left and right flexures are mobilized while preserving collateral circulation.
  • Step 7: Graft Measurement and Transection - The required length of the colon graft is determined by measuring the distance from the tethering left colic artery to the planned anastomosis site. The colon is then transected at the marked site.
  • Step 8: Anastomosis - The colon graft is placed in a bowel bag for protection as it is passed into the posterior mediastinum. The thoracic esophagus and colon graft are anastomosed, followed by securing the graft at the diaphragm and anastomosing the distal end of the colon graft to the stomach.
  • Step 9: Restoration of Continuity - The remaining segments of the colon, both distal and proximal to the harvested segment, are anastomosed to restore continuity of the gastrointestinal tract.
  • Step 10: Placement of Jejunostomy Tube - A jejunostomy tube is placed for feeding and decompression, ensuring that the patient can receive nutrition post-operatively.

3. Post-Procedure

After the completion of the partial esophagectomy, patients typically require close monitoring in a postoperative setting. Expected recovery includes managing pain, monitoring for any signs of complications such as infection or anastomotic leaks, and ensuring proper nutrition through the jejunostomy tube. Patients may need to stay in the hospital for several days to ensure adequate recovery and to begin transitioning to oral intake as tolerated. Follow-up care is essential to assess the healing of the anastomosis and to monitor for any long-term complications related to the surgery.
