Partial median sternotomy: anterior approach to the upper thoracic esophagus.

Based upon experience with cervicothoracic esophageal carcinomas in which resection of the manubrium, adjacent clavicles, and ribs has facilitated exposure of the tumor, it has been found that a partial upper sternal split (without resection) provides access to the upper thoracic esophagus to the level of the carina. With a knowledge of the anatomic relationships of the esophagus in this area, this direct anterior approach has been used for both benign and selected malignant diseases involving the upper thoracic esophagus. A partial median sternotomy has been used in 11 patients with the following esophageal pathology: upper- and/or middle-third malignancy (six), benign upper-third stricture (three), perforation of upper-third esophagogastric anastomotic stricture (one), and cricopharyngeal achalasia in association with a chronic cervical compression fracture that prevented extension of the neck (one). The following operations were performed: blunt esophagectomy with cervical esophagogastric anastomosis (six), segmental esophageal resection with primary anastomosis (three), drainage of perforation (one), and extended cervical esophagomyotomy (one). A chylothorax developed in one patient with carcinoma, the only major postoperative complication in this group. Transient hoarseness occurred in two patients. Careful evaluation of the patient with upper thoracic esophageal pathology, focusing on the type, extent, and location of the abnormality relative to the level of the carina, as well as the habitus of the patient, often indicates that a partial sternotomy can be utilized to facilitate the operation.
