High rates of complications in advanced stage gastric cancer after laparoscopic gastrectomy

Abstract

Purpose: The inclusion criteria for laparoscopic gastrectomy have recently been expanded, and this has led to an increase in the number of publications describing the laparoscopic treatment of advanced gastric cancer. The aim of this study was to evaluate morbidity in advanced stage gastric cancer (ASGC; tumor, node, metastasis [TNM] stage II–III) compared with that in early stage gastric cancer (ESGC; TNM stage I) in patients undergoing laparoscopic assisted distal gastrectomy (LADG). Methods: The clinical data of 448 consecutive patients who underwent LADG with R0 resection for gastric cancer at the Gyeongsang National University Hospital were retrospectively analyzed. Results: The morbidity and mortality rates for radical distal gastrectomy were 20.3% (91/448) and 0.2% (1/448), respectively. Wound problems were the most common complication (4.7%, n=21), followed by leakage (4.5%, n=20), and postoperative bleeding (3.8%, n=17). We found ASGC had higher frequencies of postoperative ileus (0.8% vs. 5.4%), wound problems (3.1% vs. 10.9%), and pulmonary complications (4% vs. 7%) than ESGC in the LADG (P<0.05). Conclusion: Among patients who underwent LADG, ASGC patients had higher rates of postoperative ileus and wound and pulmonary complications than ESGC patients. ASGC patients should be closely monitored for these complications after LADG.
