[Distal subtotal gastrectomy and gastreectomy in surgical treatment of patients with gastric cancer: a systematic review and meta-analysis].

The choice of distal subtotal gastrectomy and gastrectomy with D2 lymphadenectomy in patients with distal gastric cancer is not regulated by evidence-based medicine. The boundaries of minimal surgical clearance from the tumor edge vary from 2.5 cm to 6 cm. An updated meta-analysis shows that postoperative mortality and morbidity are significantly higher after gastrectomy compared to distal subtotal gastrectomy while overall 5-year survival is similar.
