Abstract
To evaluate the effectiveness of laparoscopic assisted total gastrectomy (LATG), we compared its early surgical outcomes with those of conventional open total gastrectomy (OTG) in patients who were diagnosed as having early gastric cancer preoperatively. We retrospectively analyzed early surgical outcomes in 190 consecutive patients who underwent total gastrectomy for early gastric cancer between January 2009 to April 2010. The patients were divided into those who underwent LATG and those who underwent OTG. Their early surgical outcomes were analyzed to evaluate the effectiveness of LATG. There was no significant difference in postoperative complication rates (P = 0.291). But in the analysis of other early surgical outcomes, we found that LATG could improve time to first flatus (P < 0.001), time to commencement of soft diet (P = 0.034), administration of analgesics (P = 0.024), pain score (Numeric Rating Scale), and hospital discharge (P = 0.045). Although LATG didn't show better results for postoperative complications than those of OTG, LATG contributes to the improvement of early surgical outcomes, including bowel movement, pain score and hospital discharge. Therefore, we suggest that LATG could be a method to improve early surgical outcomes in patients who need total gastrectomy.
