Brief Summary
The goal of this clinical trial is to learn if enema works to prevent low anterior resection syndrome (LARS) in adults. The main questions it aims to answer are:
- 1.To describe the level of stoma adaptation before and after the patients received enemas during the stoma period as well as the levels and trends of LARS, bowel function, sleep quality, and quality of life after stoma reduction surgery
- 2.To compare the effects and advantages and disadvantages of antegrade and retrograde enema, and to investigate whether these two types of enema can provide safe and effective preventive measures for the prevention of LARS, the improvement of bowel function, and the enhancement of sleep and quality of life in rectal cancer patients after low anterior resection.
- 3.Receive either antegrade or retrograde enema or no enema based on the standard of care at 1 month after anterior rectal resection, until the ileostomy reversal.
- 4.Keep a diary of their symptoms.

Study Arms (3)
standard of care
NO INTERVENTIONThe standard of care (SOC) was implemented following low anterior resection, which included the distribution of pamphlets and instructional videos to patients and their caregivers.
antegrade enema
EXPERIMENTALParticipants assigned to this group received the standardized of care as the basis for the intervention. The enema is administered through the distal end of the ileocecal stoma, directed towards the anus.
retrograde enema
EXPERIMENTALParticipants assigned to this group received the standardized of care as the basis for the intervention. The enema is administered retrogradely via the anus.
Interventions
The enema is administered retrogradely via the anus. The enema commences one month post-operatively for patients with well-healed wounds, absence of stoma-related complications, and no evidence of anastomotic leakage upon digital examination, until ileostomy reversal. the catheter is gently and slowly inserted 7-10 cm through the anus. The initial irrigation volume is set at 500 ml and is gradually increased based on the patient's tolerance, up to a maximum of 1000 ml. 39-41°C warm water is the choice. Enemas are administered twice weekly, with each session limited to a duration of 30 minutes.

The enema commences one month post-operatively for patients with well-healed wounds, absence of stoma-related complications, and no evidence of anastomotic leakage upon digital examination, until ileostomy reversal. Using a disposable catheter, insert it about 20 cm. The initial irrigation volume is set at 500 ml and is gradually increased based on the patient's tolerance, up to a maximum of 1000 ml. 39-41°C warm water is the choice. Enemas are administered twice weekly, with each session limited to a duration of 30 minutes.
