In our previous survey of experts, surgeon’s decision-making process (DMP) about protective ileostomy (PI) creation after anterior resection was investigated. Based on our previous data, a multiple choice questionnaire has been developed. The aim is to perform a quantitative analysis of the results obtained from an international survey and to describe the clinical practice worldwide. Ten questions were related to participants’ demographics and, 20 questions (of which 17 Likert scale questions) investigated the DMP regarding PI creation. To evaluate the tendency of the answers in the Likert-type questions, the mean of the answers obtained was compared with the mean point of the Likert scale. The survey was completed by 1019 physicians. Neoadjuvant chemoradiotherapy and distance of the anastomosis from the anal verge ≤ 10 cm were each considered alone sufficient to justify creation of a PI, with statistically significant differences in comparison to the mean point of the scales in (p = < 0.0001 in both cases). Total Mesorectal Excision alone was not considered a factor sufficient to create a PI (p = 0.416). Most of the participants agree to define their approach to create a PI “tailored” to patients’ risk factors (p = < 0.0001) and “influenced by my experience” in case of patients with low/moderate risk of anastomotic leakage (p = < 0.0001). This study provides useful insights on the worldwide clinical practice regarding creation of PI following anterior resection. Given the lack of standardization and evidence-based guidelines, this analysis may be helpful to assist surgeons’ practice.
