In the March 2021 issue (273[3]:557–563) of Annals of Surgery, the article by Beelen et al., “Decreasing trends in intestinal resection and re-resection in Crohn's disease: a nationwide cohort study”, included incorrect data in a part of the results section. The discovered error did not alter the conclusion of the manuscript. The online version of the article has been updated to include all of the necessary changes, and we have provided a list of the important text corrections and revised versions of Figure 1 and Figure 2 below, and Supplemental Figure in the Supplemental Materials. Please note that we refer readers to the updated online version of the article. The authors apologize for this error.

Intestinal resection rate in CD patients between 1991 and 2015 (A) its corresponding piecewise linear model (B) and corresponding 95% confidence intervals. Prevalence of Crohn's disease: prevalence per 100,000 persons.
Intestinal resection rate in CD patients according to anatomic location: Ileocolonic, colon, small bowel, and rectum and corresponding 95% confidence interval. Prevalence of Crohn's disease: prevalence per 100,000 persons.

Page 557, paragraph 4 of the abstract, lines 3–5 should read: “The annual intestinal resection rate decreased nonlinearly from 1.9/100,000 (1991) to 0.2/100,000 (2015). A significantly steeper-decrease was observed before 1999 (slope –0.13) as compared to subsequent years (slope –0.03) (p<0.001).”

Page 558, paragraph 2 of the results, lines 10–33 should read: “The total intestinal resection rate decreased nonlinearly during the study period from 1.9/100,000 in 1991 to 0.2/100,000 in 2015 (Figure 1A). The piecewise linear model used a breakpoint in 1999 with a slope of -0.13 (95% CI [-0.15, -0.11]) per year until 1999 and -0.03 (95% CI [-0.04, -0.03]) per year after 1999 (both p<0.001) (Figure 1B). Similar nonlinear decreasing trends were observed for all subgroups of intestinal resection. The overall decrease was most substantial for ileocolonic resections, from 0.7/100,000 in 1991 to 0.1/100,000 in 2015. Colon and small bowel resections decreased from 0.6/100,000 in 1991 to 0.05/100,000 in 2015 and 0.6/100,000 in 1991 to 0.07/100,000 in 2015, respectively (Figure 2). Rectum resection rates decreased from 0.05/100,000 in 1991 to 0.001/100,000 in 2015. Piecewise linear models used the year 2000 as the breakpoint for ileocolonic resections and small bowel resections, with corresponding slopes until and after 2000 of –0.05 (95% CI [-0.05, –0.04]) and –0.01 (95% CI [-0.01, –0.01]), respectively, for ileocolonic and -0.03 (95% CI [-0.04, -0.03]) and -0.01 (95% CI [-0.02, -0.01]) for small bowel resections (all p<0.001). The year 1998 was found to be the breakpoint for colon resections, with a slope of –0.04 (95% CI [-0.05, –0.04]) until 1998 and –0.01 (95% CI [-0.01, –0.01]) after 1998. Rectum resection models showed a linear decrease without the need for a breakpoint. Here the slope was –0.002 (95%CI [-0.002, –0.001]) (Supplementary figure, Supplemental Digital Content 3,”
