Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the study is to determine if short-term outcomes of colon resections after full bowel preparation (mechanical bowel preparation plus oral antibiotics) are superior to colon resections with no bowel preparation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The design involves random allocation of eligible patients to full bowel preparation or no bowel preparation in 1:1 ratio. After that colon resection is performed in both groups.

Short-term outcomes are assessed in 30 day period after surgery. This is a superiority trial evaluating statistical superiority. Rate of anastomotic leak is anticipated to decrease from 8% (data from local registry) to 3%. For power of 80% enrolment of 586 patients is required.

The intent-to-treat principle is used for the data analysis.
