Prognostic risk factors of early gastric cancer-a western experience.

Purpose: Lymph node metastasis (LNM) is the leading cause of tumor recurrence in early gastric cancer (EGC). Since endoscopic resection (ER) can be performed in EGC with curative intention when no LNM are present, this study wants to determine the risk factors for LNM in EGC.

Methods: One hundred twenty-four patients who have had an operative resection because of EGC were analyzed.

Off-pump coronary artery bypass prevents visceral organ damage.

Objectives: Visceral malperfusion after coronary artery bypass grafting (CABG) results in high morbidity and mortality. This study was designed to evaluate the effect of CABG performed by surgical techniques on visceral perfusion and function.

Methods: Pigs (n = 28) were studied in four groups: I.
