Total thoracic esophagectomy for esophageal cancer.

BACKGROUND

Many current methods of esophageal resection have drawbacks that result in inadequate proximal resection, inadequate lymphadenectomy, and difficult gastric and splenic access. We describe a technique that allows reliable and safe access to the chest, abdomen, and neck.

STUDY DESIGN

From 1988 to 1995, 113 patients (82 men; mean age 65.3 +/- 4.5 years) with carcinoma of the esophagus or esophagogastric junction (middle third in 34, lower third in 41, and cardia in 38) underwent total thoracic esophagectomy. The histology was adenocarcinoma in 71 (62.8%), squamous cell carcinoma in 32 (28.3%), and undifferentiated carcinoma in 10 (8.9%) of the patients; 57 tumors (50.5%) were stage III. The esophagus and stomach were mobilized through a left thoracoabdominal incision. After completion of the esophageal resection, the fundus of the stomach was sutured to the esophageal stump to allow later delivery of the stomach into the neck. The esophagogastric anastomosis was performed with continuous single-layer absorbable suture through a left oblique cervical incision.

RESULTS

The mean duration of the operation was 309.2 +/- 47.9 minutes. Hospital stay ranged from 5 to 49 days (median, 12 days). The perioperative mortality rate was 4.4%. Anastomotic leak occurred in six patients (5.3%), one of whom died. The proximal resection margin was microscopically free of tumor in all cases, and with a minimum followup period of 18 months, there has been no anastomotic recurrence in any patient. Actuarial survival at 1 year was 63.4% +/- 4.9%, at 3 years 41.4% +/- 5.9%, and at 5 years 22.7% +/- 6.3%.

CONCLUSIONS

Total thoracic esophagectomy through the left chest with a separate left cervical incision allows clear access to the esophagus and stomach and good tumor clearance. This procedure may be performed with a low rate of anastomotic leakage, a very low mortality rate, and no anastomotic tumor recurrence.
