Development and Validation of a Post-Radiotherapy Prediction Model for Bowel Dysfunction After Rectal Cancer Resection.

Background & Aims: The benefit of radiotherapy for rectal cancer is based largely on a balance between a decrease in local recurrence and an increase in bowel dysfunction. Predicting postoperative disability is helpful for recovery plans and early intervention. We aimed to develop and validate a risk model to improve the prediction of major bowel dysfunction after restorative rectal cancer resection with neoadjuvant radiotherapy using perioperative features.

Risk Factors of Delayed Recovery of Gastrointestinal Function After Ileostomy Reversal for Rectal Cancer Patients.

Purpose: The aim of this study was to identify the risk factors associated with delayed recovery of gastrointestinal function after ileostomy reversal for rectal cancer patients.

Methods: In this retrospective study, the data of rectal cancer patients who underwent ileostomy reversal from January 2018 to December 2019 at the Sixth Affiliated Hospital of Sun Yat-sen University were assessed to investigate potential risk factors of delayed flatus after ileostomy reversal.

Results: A total of 282 patients were eligible for this study.
