Abstract

Background: Gastric cancer continues to be one of the malignant tumor types with high morbidity and mortality worldwide. Although remarkable improvements have been made to combat gastric cancer, surgery is still the first choice of treatment for gastric cancer.

Methods: This was a single-center and retrospective study. A total of 110 patients who underwent radical gastrectomy with D2 lymph node dissection between 2014 and 2017 were included in this study, and all patients were treated by the same medical staff. Based on the median operating time, patients were grouped into a long-time group (>180 min) and a short-time group (≤180 min). Influences of operating time on outcomes of patients in the short-term and long-term groups were analyzed.

Results: The long-time group showed a higher incidence of postoperative complications compared with the short time group (P < 0.01) with a significant decrease in serum albumin and the prognostic nutritional index value. Moreover, a long operating time was often caused by the operating start time (P < 0.001), excision difficulty caused by lager tumor size (P < 0.001), worse tumor differentiation, and deeper tumor invasion (P < 0.05). However, length of operating time did not significantly influence overall survival of patients who underwent radical gastrectomy.

Conclusions: The results suggested that operating time might be an indicator of the incidence of postoperative complication and that several important variables, such as prognostic nutritional index, serum albumin, operating start time, and excision time, could be intervened in the perioperative period to help patients gain a better outcome after gastrectomy.
