“…Recently, our study group investigated the impact of timing within the week on the short-term results following elective right hemicolectomy for colon cancer; it was not proven that there was evidence of worse outcomes on Fridays compared to Mondays. 24 Notably, a smaller number of elective right hemicolectomies were performed on Fridays, similar to the finding on PDs. This reduction in the number of the surgeries may have also reduced the total workload burden during the weekends and could have some role in equalizing surgical mortality throughout the week.…”

Background/Purpose: The day of the week can impact medical treatment outcomes; however, few large-scale, disease-specific studies have focused on the association between the day of the week and mortality in patients after pancreatoduodenectomy for pancreatic head cancer.Methods: Data were obtained from the National Clinical Database. Twentytwo clinical variables were adopted for hierarchal logistic regression modeling to determine adjusted odds ratios (ORs) for surgical mortality after elective pancreatoduodenectomy. Results:The 30-day mortality and surgical mortality rates were 1.0% and 1.7%, respectively (n = 29 720). Surgeries were performed the least on Fridays (13.4%) compared with other weekdays. Crude rates of severe postoperative complications (mean, 14.1%; range, 13.5%-14.8%) and pancreatic fistulas (mean, 10.0%; range, 9.6%-10.3%) remained stable throughout the week. Unadjusted/adjusted ORs did not significantly differ between Friday and Monday (0.868, 95% CI: 0.636-1.173, P = .365, and 0.928, 95% CI: 0.668-1.287, P = .653, respectively), and results were similar for the remaining weekdays. Nineteen independent factors were associated with surgical mortality.

“…42 Moreover, the mortalities after right hemicolectomy or pancreatoduodenectomy were not affected by day of the week. 43,44 In addition, in emergency surgery for acute diffuse peritonitis, antithrombotic drug usage was associated with a slight increase of intraoperative blood loss, which was thought to have little effect on clinical practice. 45 Much new evidence using the huge database of the NCD has been successively published.…”

Aim The National Clinical Database (NCD) of Japan is a nationwide data entry system for surgery, and it marked its 10th anniversary in 2020. The aim was to present the 2020 annual report of gastroenterological surgery of the NCD. Methods The data of the surgical procedures stipulated by the training curriculum for board‐certified surgeons of the Japanese Society of Gastroenterological Surgery in the NCD from 2011 to 2020 were summarized. Results In total, 5 622 845 cases, including 593 088 cases in 2020, were extracted from the NCD. The total number of gastroenterological surgeries increased gradually in these 10 years, except for the year 2020 due to the COVID‐19 pandemic. The annual number of surgeries of each organ, except the pancreas and liver, decreased by 0.4%–13.1% in 2020 compared to 2019. The surgical patients were consistently aging, with more than 20% of all gastroenterological surgeries in 2020 involving patients aged 80 years or older. The participation of board‐certified surgeons increased for each organ (75.9%–95.7% in 2020). The rates of endoscopic surgery also increased constantly. Although the incidences of postoperative complications of each organ increased by 0.7%–7.9% in these 10 years, postoperative mortality rates decreased by 0.2%–1.5%. Conclusions We present here the short‐term outcomes of each gastroenterological operative procedure in 2020. This review of the 10‐years of NCD data of gastroenterological surgery revealed a consistent increase of the number of surgeries (except for in 2020), especially endoscopic procedures, and aging of the Japanese population. The good safety of Japanese gastroenterological surgeries was also indicated.
