CPT® Code 43361

Gastrointestinal reconstruction for previous esophagectomy, for obstructing esophageal lesion or fistula, or for previous esophageal exclusion; with colon interposition or small intestine reconstruction, including intestine mobilization, preparation, and anastomosis(es)

The CPT® Code 43361 refers to a complex surgical procedure known as gastrointestinal reconstruction, specifically performed following a previous esophagectomy. This procedure is indicated for patients who have obstructing esophageal lesions, fistulas, or have undergone esophageal exclusion. The reconstruction can involve the use of either a section of the colon or the small intestine, which is selected based on the specific clinical scenario and the surgeon's assessment. The procedure entails several critical steps, including the mobilization and preparation of the intestine or colon, as well as the creation of anastomoses, which are surgical connections between the segments of the gastrointestinal tract. The complexity of the procedure is underscored by the need to preserve blood supply to the graft, ensuring adequate perfusion, and the potential requirement for additional surgical interventions, such as enlarging the thoracic inlet or performing a median sternotomy, to facilitate access to the anastomosis site. Overall, this procedure aims to restore gastrointestinal continuity and function in patients who have experienced significant esophageal pathology.
