Laparoscopic gastrectomy for cancer.

Gastric cancer is common worldwide. Tumor location and disease stage differ between Asian and Western countries. Western patients often have higher BMIs and comorbidities that may make laparoscopic resections challenging. Multiple trials from Asian countries demonstrate the benefits of laparoscopic gastrectomy for early gastric cancer while maintaining equivalent short-term and long-term oncologic outcomes compared with open surgery. The outcomes of laparoscopy seem to offer equivalent results to open surgery. In the United States, laparoscopic gastrectomy remains in its infancy and is somewhat controversial. This article summarizes the literature on the epidemiology, operative considerations and approaches, and outcomes for laparoscopic gastrectomy.
