Purpose: Although laparoscopy-assisted gastrectomy (LAG) has become a popular treatment option for early gastric cancer, information about postoperative complications is limited in the literature and their risk factors vary among investigators. We analyzed the complications and their risk factors of LAG.
Methods: We performed LAGs in 92 gastric cancer patients from July 2006 to December 2009. LAG indication was gastric cancer preoperatively diagnosed as cT1N0. Clinical and operative data and perioperative complications were retrospectively reviewed. According to the surgical experience, cases were divided into early (1∼40) and late (41∼92) groups because operative times stabilized after the 40th case.
Results: There were no open conversion or mortality cases. Complications occurred in 11 patients. Two of them were non-surgical complications: postoperative delirium and cerebral infarction. Surgical complications were ischemic necrosis of transverse colon, duodenal stump leakage, anastomotic bleeding, leakage and stenosis. Univariate analysis proved that lymph node metastasis, and comorbidities were related to complication rate (P=0.000, P=0.032). Multivariate analysis proved that lymph node metastasis was the most important risk factor of complication (P=0.001). Surgical experience was not related to complication rate (12.5% in early period and 11.5% in late period, P=1.000).
Conclusion: Complication rate of LAG was acceptable (11.9%). According to this study, unexpected lymph node metastasis is thought to be the most important risk factor for complications of LAG. Therefore, it is possible to accomplish lower complication rates in this procedure with careful patient selection through accurate preoperative evaluation.
