Triethanolamine cream retention enema was given once every night before going to bed during radiotherapy until the end of radiotherapy. Triethanolamine cream retention enema was given once before going to bed the day after radiotherapy for 3 months.

Preparation method: Pull out the syringe piston, add 15ml triethanolamine cream, add 30ml normal saline, gently pat, shake well.

Specific methods of retention enema: at night before going to bed, empty urine and feces, prepare enema liquid into the syringe, connect the special catheter, and insert the other end of the special catheter into the anus (the special catheter can be applied with lubricant such as tea oil before insertion).

Use a special catheter, insert a special catheter about 15cm from the anus, and inject enteral liquid while withdrawing, so that the liquid is retained in the rectum; The above treatment was performed before bed and retained overnight.

RTOG/EORTC criteria were used to evaluate the severity of acute and chronic radiation rectal injury. The time (days) of acute radiation rectal injury were evaluated and recorded

Clinical symptoms were assessed using the Simple Clinical Colitis Activity Index (SCCAI) designed by the Inflammatory Bowel Disease Research Group at the Royal Free Hospital School of Medicine.

SCCAI in this study included 6 items, with a total score of 0-16. The higher the score, the more severe the symptoms.
