title: Evaluation of Clavien-Dindo classification in patients undergoing total gastrectomy for gastric cancer.
abstract: The Clavien-Dindo classification for postoperative complications has been established as a standardized system and applied in many fields of surgery. The aim of our study was to assess the complications after total gastrectomy using the Clavien-Dindo classification and identify risk factors related to them. Four hundred and fifteen patients who underwent total gastrectomy for gastric cancer between April 2009 and September 2014 were enrolled in this study. Postoperative complications were graded, and possible risk factors related to complications were analyzed. The overall complication rate was 13.3 %, with the severe complications classified as grade III or above accounting for 3.1 %. Age of 65 years old or more, higher TNM staging, and open surgery were identified as independent risk factors for overall complications. Age of 65 years old or more, ASA score of 3 or more, multiorgan resection, and retrieved lymph nodes of 30 or more were identified as independent risk factors for severe complications. The Clavien-Dindo system has a broad applicability and facilitates the assessment on the incidence and severity of complications. Large-scaled, prospective clinical trials using the classification are necessary to evaluate the postoperative complications of total gastrectomy for gastric cancer.
