The Risk Factors of Reflux Complication after Gastrectomy for Proximal Gastric Cancer

ABSTRACT

PURPOSE: The aim of this study was to investigate the risk factors of reflux associated complications (reflux symptoms, reflux esophagitis, and esophageal stricture) after gastrectomy for proximal gastric cancer. METHODS: 150 patients with proximal gastric cancer were included from January 2005 to December 2008. Their medical and surgical records were retrospectively analyzed concerning clinical and pathologic characteristics, operation methods, morbidity, reflux associated complications and nutritional states. RESULTS: Tumor sizes and operation methods were statistically significant in univariate analysis of risk factors for reflux associated complications (P0.05). However, reflux complications were significantly more common in proximal gastrectomy groups (72.4%) than in total gastrectomy groups (29.5%). Severe reflux esophagitis (LA classification C or D) was found in only proximal gastrectomy groups. CONCLUSION: Total gastrectomy is favorable for proximal early gastric cancer in terms of reduced esophageal reflux complications.
