简要总结
The rate of anastomotic leakage after laparoscopic anterior resection（LAR） for medium & low rectal cancer is still high. the transanal drainage tube (TDT) was thought to be useful for deduce the rate. There were several studies, but most of them were not randomized controlled trial (RCT) studies. There was only one RCT study with enough samples, but it was designed for open anterior resection, and the patients underwent diverting stoma were excluded, so there was the selection bias. LAR now is thought to been with the same effect, and it is safe and feasible. So a RCT investigation for the use of TDT for prevention of anastomotic leakage after LAR for medium & low rectal cancer is needed.
详细描述
Patients were randomly assigned to two groups, the TDT and non-TDT group after the laparoscopic LAR and DST procedure was decided during operation. Randomization was obtained through a computer-generated random number sequence allocation. Surgeon blinding was performed to ensure all the intraoperative decisions made by the surgeon were not interfered with by the grouping. All the operative procedures fully complied with the guideline for the diagnosis and treatment of colorectal cancer and the technique of total mesorectal excision (TME). The preservation of the left colonic artery was judged by the surgeon according to his own experiences and assessment of the patient's conditions. When the anastomosis was accomplished, the discretion of DS construction was made by the surgeon based on assessing the risk factors of AL. Pelvic drainages were used in all cases in this study. After completion of the anastomosis and further DS construction if necessary, the surgeon would be notified to implement the intervention based on the randomizing results.

结局指标
主要结局
Incidence of AL
时间窗: 30 days after surgery
The primary endpoint was the AL within 30 days after surgery. AL is defined when the following symptoms were noticed: abdominal pain, fever, peritonitis, leukocytosis, procalcitonin (PCT) or c-reactive protein (CRP) increase, discharge of feces, pus, or gas from the drainage or vagina, septicemia with pelvic abscess. All clinically suspicious symptoms were confirmed by digital rectal examination, computed tomography (CT) scan or surgery when necessary. The severity grading of AL was defined according to the International Study Group of Rectal Cancer. In the present study, AL was referred to grade B and C, asymptomatic AL (grade A) was not considered because no active therapeutic intervention was required.
