Surgical Option for Sufficient Safety Margine in Locally Advanced Type II Cardia Cancer-Left Colon Interposition

ABSTRACT

PURPOSE: Radical surgery is the standard therapy for patients with resectable cardia cancer. In the case of type II disease with esophageal invasion, a transhiatal extended radical total gastrectomy is needed or a gastroesophagectomy through an abdomino-thoracotomy, depending on the extent of the esophageal invasion. We analyzed the indications and outcome of left colon interposition as an esophageal substitution. MATERIALS AND METHODS: Between 1 January 1994 and 31 December 2006, 10 patients underwent left colon interposition after gastroesophagectomy through an abdomino-thoracotomy or the tanshiatal approach for type II cardia cancer at the Department of surgery, Yonsei University College of Medicine. The outcomes of these patients were reviewed and compared, with those who underwent a Roux-en-Y, by gender and age matched analysis, retrospectively. RESULTS: There were nine males and one female with a mean age of 52.5 (range, 16~72). The operation time was 449.00+/-87.39 minutes. The mean distance between the proximal resection margin and the cancer was 6.56+/-3.65 cm; the maximum size of the tumor was 9.90+/-3.97 cm. These measures differed significantly from patients who underwent Roux-en-Y. The patients had a double primary cancer in the cardia and esophagus. There were no events of colon necrosis. However, a pneumothorax occurred in one patient (10%) and a proximal anastomotic stricture occurred in one patient. There were no reports of heartburn, regurgitation, thoracic or epigastric fullness, and one patient even gained weight, 16 kg. CONCLUSION: Colon interposition after esophagogastrectomy was safe and effective and should be considered as an additional surgical option for locally advanced type II cardia cancer patients with esophageal invasion.
