Abstract
BACKGROUND
The role of laparoscopic surgery for the treatment of gastric cancer is still controversial, particularly in terms of oncologic efficacy. The aim of this study was to compare short-term outcomes of laparoscopic and open resection for gastric cancer at a single Western institution.
SUBJECTS AND METHODS
This study was designed as a matched cohort study from a prospective gastric cancer database. Forty-one patients undergoing laparoscopic gastrectomy for gastric cancer between June 2008 and January 2012 were matched with 41 patients undergoing open gastrectomy in the same time period. Patient pairing was done according to age, gender, type of gastrectomy (subtotal or total), and tumor stage via a randomized statistical method. The short-term outcomes and oncologic adequacy of the laparoscopic and open procedures were compared. A D2 lymph node dissection was performed in the majority of patients in both groups.
RESULTS
The two study groups were similar with respect to patient and tumor characteristics. Laparoscopic procedures were associated with a decreased blood loss (118.7 versus 312.4 mL, P<.005), incidence of surgery-unrelated complications (3 versus 9 patients, P<.05), and duration of hospital stay (8.1 versus 11.5 days, P<.05) but increased operative time for both subtotal (223.5 versus 158.2 minutes, P<.001) and total (298.1 versus 185.5 minutes, P<.001) gastrectomies. The mean number of retrieved lymph nodes after D2 dissection was similar: 30.0 for laparoscopic and 29.7 for open patients.
CONCLUSIONS
Within the limitations of a nonrandomized analysis, this study shows that the laparoscopic approach is a safe and oncologically adequate option for the treatment of gastric cancer, which compares favorably with open gastrectomy in short-term outcomes.
