Prospective randomized study of open versus laparoscopy-assisted distal gastrectomy with extraperigastric lymph node dissection for early gastric cancer.

BACKGROUND: Laparoscopy-assisted surgery with extraperigastric lymph node dissection for gastric cancers has been described, but the clinical benefits of these surgeries still are unclear. Short-term clinical outcomes were compared between laparoscopy-assisted distal gastrectomy (LADG) and conventional open distal gastrectomy (ODG) for early gastric cancer in a prospective randomized fashion.
METHODS: For this study, 28 patients with early gastric cancers in the lower half of the stomach were randomly assigned to either LADG (n = 4) or ODG (n = 14). Postoperative pain, levels of acute inflammatory responses, and pathologic evaluation of the operative specimens were compared.
RESULTS: The LADG group required a significantly shorter period of postoperative epidural anesthesia, showed significantly lower levels of serum interleukin-6 and C-reactive protein, and had no major postsurgery complications. Pathologic examinations showed that surgery was equally radical in the two groups.
CONCLUSION: The findings show that LADG with extraperigastric lymph node dissection is a safe and less invasive alternative to the open procedure.
