CPT® Code 43340

The procedure described by CPT® Code 43340 is known as esophagojejunostomy performed via an abdominal approach. This surgical intervention is typically indicated when there has been a prior surgical removal of the stomach, such as in cases where an esophagogastrojejunostomy has failed. The failure may necessitate the excision of an ischemic segment of the jejunum, which is then re-anastomosed to the esophagus. The abdominal approach, also referred to as a transhiatal approach, involves making an incision in the upper abdomen to explore the peritoneal cavity. This allows the surgeon to access the lower posterior mediastinum and distal esophagus effectively. The procedure is critical for restoring continuity between the esophagus and the jejunum, particularly in patients who have undergone significant gastrointestinal surgeries that compromise normal digestive pathways.
