Abstract
Background
To investigate the incidence of and factors associated with postoperative complications and failure to rescue following laparoscopic and open gastrectomy for gastric cancer.
Study design
We analyzed the records of 4124 patients who underwent a laparoscopic or open gastrectomy for gastric cancer. One-to-one propensity score matching was performed to compare the difference between the two groups.
Results
A total of 4124 patients were included in the study, 627 of whom (15.2 %) developed postoperative complications. Postoperative deaths occurred in 23 (0.6 %) patients with serious complications. In the propensity score matching analysis with 1361 pairs, no significant differences in the rates of overall complications (14.2 vs. 16.5 %, p = 0.093) were observed between laparoscopic and open gastrectomy group. In-hospital mortality decreased in patients who underwent laparoscopic gastrectomy compared to patients who underwent open gastrectomy (0.3 vs. 1.2 %, p = 0.004). Failure to rescue rates were lower in patients who underwent laparoscopic gastrectomy (2.1 vs. 7.6 %, p = 0.008). Multivariate analysis showed that older age, tumor location, TNM stage classification, extent of gastric resection, operative time and intra-operative blood loss were adverse risk factors for postoperative complications. Laparoscopic gastrectomy was found to be a protective factor for failure to rescue. Complications associated with failure to rescue included abdominal bleeding, anastomotic leakage and cardiac events. In-hospital mortality increased as the number of complications per patient increased.
Conclusions
Assuming equal competence with open and laparoscopic approaches of a surgeon, the proportion of patients with postoperative complications were similar among those who underwent laparoscopic gastrectomy compared to patients who underwent open gastrectomy. However, when complications occurred, patients with open gastrectomy were more likely to die.
