Correction to: Outcomes of endoscopic treatment for malignant biliary obstruction in patients with surgically altered anatomy: analysis of risk factors for clinical failure (Surgical Endoscopy, (2021), 35, 1, (232-238), 10.1007/s00464-020-07385-y)

There are several places where the P-value and Odds ratio in Table 3 are incorrect: these are shown in the corrected Table 3. The following two sentences related to Table 3 should be corrected: 1. In the Results section of the Abstract, the sentence “In multivariate analysis, the presence of peritoneal dissemination (odds ratio, 7.3; 95% confidence interval, 1.5–43.5, p = 0.02) was as an independent risk factor for clinical failure.” should read: “In multivariate analysis, the presence of peritoneal dissemination (odds ratio, 6.8; 95% confidence interval, 1.6–32.8, p = 0.008) was as an independent risk factor for clinical failure.” 2. In the last line of Clinical outcome section, the sentence “In multivariate analysis, the presence of peritoneal dissemination (odds ratio, 7.3; 95% confidence interval, 1.5–43.5) (p = 0.02) was as an independent risk factor for clinical failure.” should read: “In multivariate analysis, the presence of peritoneal dissemination (odds ratio, 6.8; 95% confidence interval, 1.6–32.8) (p = 0.008) was as an independent risk factor for clinical failure.” The authors regret these errors.
