Textbook outcome as a predictor of long-term prognosis in ampullary cancer: A retrospective cohort study

Figure 1 Textbook outcome achievement after pancreaticoduodenectomy for ampullary cancer and annual trends during the study period. A: Achievement rates of individual textbook outcome components and the overall textbook outcome rate after pancreaticoduodenectomy; B: Annual surgical volume of patients with ampullary cancer undergoing pancreaticoduodenectomy and annual textbook outcome rates from 2012 to 2022; C: Annual number of patients who failed to achieve textbook outcome and the distribution of non-textbook outcome events from 2012 to 2022. POPF: Postoperative pancreatic fistula; PPH: Postpancreatectomy hemorrhage; AC: Ampullary cancer; TO: Textbook outcome.

Figure 2 Kaplan-Meier curves for overall survival after pancreaticoduodenectomy in patients with ampullary cancer. A: Overall survival curve for the entire cohort of patients with ampullary cancer (n = 347); B: Overall survival curves stratified by textbook outcome achievement. Survival differences between groups were compared using the log-rank test. The numbers at risk are shown below the plots. TO: Textbook outcome.

Figure 3 Kaplan–Meier curves for disease-free survival after pancreaticoduodenectomy in patients with ampullary cancer. A: Disease-free survival curve for the entire cohort of patients with ampullary cancer (n = 347); B: Disease-free survival curves stratified by textbook outcome achievement. Survival differences between groups were compared using the log-rank test. The numbers at risk are shown below the plots. TO: Textbook outcome.
