Laparoscopic versus open distal gastrectomy for locally advanced gastric cancer: a case–control study

Abstract

In a non-specialized setting, laparoscopic distal gastrectomy (LDG) for locally advanced diseases remains controversial, particularly given to the technical demands of the learning curve required to perform an adequate resection with D2 lymph node dissection. Inclusion criteria for this statistically generated matching controlled study were all patients who underwent subtotal laparoscopic gastrectomies from January 2006 until September 2009 for locally advanced gastric adenocarcinoma (stage II-IIIb), compared with matched patients who underwent the same procedure in an open fashion during the same period. Sixty case-matched patients were evaluated (30 laparoscopic vs. 30 open). Operative time was significantly longer (p<0.05) for LDG. Benefits for LDG (p<0.05) were observed among surgical short-term outcome (postoperative hospital stay, ambulation, first bowel movement, first flatus, first stool, first eating and use of analgesic drugs) and postoperative non-surgical site complications (cardiopulmonary, urinary, etc.). The 42months' overall survival was similar (p=0.646). Laparoscopic gastrectomy is a safe technique in a non-academic hospital setting for locally advanced gastric cancer; it seems to be adequate in terms of margin status and adequate lymph node retrieval and is associated with additional benefits as a decreased length of hospital stay, a decreased narcotic use and fewer complications.
