Clinical Trial Summary

Transanal drainage tube (TDT) has the benefit of reducing intraluminal pressure after rectal surgery and may provide ideal regional environment for anastomotic healing. Postoperative C-reactive protein (CRP) trajectory has a high negative predictive value of 0.99 for ruling out anastomotic leak (AL). Previously, TDT was removed at the surgeon's own discretion. In the present study, we design a single arm study to investigate the safety and efficacy of CRP-guided TDT removal for AL prevention following laparoscopic anterior resection for rectal carcinoma

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	anastomotic rate	anastomotic rate	30 days after surgery
Secondary	the grades of anastomotic leak	The severity grading of anastomotic leak according to the International Study Group of Rectal Cancer	30 days after surgery
Secondary	rates of diarrhea after transanal drainage tube removal	rates of diarrhea after transanal drainage tube removal	from transanal drainage tube removal to 30 days after surgery
Secondary	visual analogue scale to assess anal postoperative pain	visual analogue scale of the included patients to assess the transanal drainage tube tolerability. Visual analogue scale ranges from 0-10. 0 indicates perfectly tolerated while 10 indicates complete intolerant and the tube has to be removed.	from the date of transanal drainage tube positioning until the tube is removed, assessed up to 2 weeks
Secondary	transanal drainage tube-related adverse events	transanal drainage tube-related adverse events such as bleeding and iatrogenic colonic perforations	from the date of transanal drainage tube positioning until the tube is removed, assessed up to 2 weeks
