Use of the TDT for Prevention of Anastomotic Leakage After Laparoscopic Anterior Resection for Rectal Cancer
A study testing with TDT and without TDT in people with Anastomotic Leakage and Rectal Neoplasms, run by Third Military Medical University at 1 site in China.
Trial summary
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. Read more about this study

Inclusion criteria: all consecutive 18 to 80 years old individuals diagnosed as primary rectal adenocarcinoma with the lower edge of the tumor less than 10 cm from the anal verge were considered eligible; with the classification of American Society of Anaesthesiologist (ASA) of I, II, or III; Laparoscopic LAR+ with double stapling technique (DST) was planned to perform for the patients. All the preoperative procedures should comply with the guideline for the diagnosis and treatment of colorectal cancer.
Exclusion criteria: The emergency operation for rectal cancer with obstruction, bleeding, or perforation would be excluded. Patients with inflammatory bowel disease (IBD), familial adenomatous polyposis (FAP), recurrent rectal cancer, or synchronous cancer would not be suitable. Patients with preoperative radiotherapy were excluded. Patients who underwent other types of surgeries for rectal cancer, including Hartmann's procedure, abdominoperineal resection (APR), intersphincteric resection ( ISR), et al. were excluded intraoperatively

About this study
Official title: The Use of the Transanal Drainage Tube for Prevention of Anastomotic Leakage After Laparoscopic Anterior Resection for Medium & Low Rectal Cancer
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.
Read the detailed description
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
with TDTProcedure or surgery
Also called with transanal drainage tube
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. In this group, a silicone tube (28Fr, Sumitomo Bakelite Co, Japan) was inserted through the anus and the tip of the tube was placed approximately 5 cm above the anastomosis at the end of the surgery in patients from the TDT group. The tube was fixed with a skin suture and connected to a drainage bag. TDT was planed to remove 3-7 days after surgery and early removal was allowed if the patient experienced intolerable pain.
without TDTProcedure or surgery
Also called without transanal drainage tube
After laparoscopic anterior resection and double-stapling technique anastomosis were finished, none additional proceduce was done.

What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of AL
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.
Measured: 30 days after surgery
Secondary outcomes (3)
Grades of AL
The grades of AL, including grade B, grade C. The severity grading of AL is defined according to the International Study Group of Rectal Cancer
Measured: within 30 days after surgery
Postoperative Anal Pain Score
Postoperative pain score. Numerical Rating Scale (NRS) for pains is used to assess the anal postoperative pain score of patients in the TDT group. NRS is the simplest and most commonly used scales for pain evaluation.The numerical scale is most commonly 0 to 10, with 0 being no pain and 10 being the worst pain imaginable. (for the details, please see the literature below FERREIRA-VALENTE M A, PAIS-RIBEIRO J L, JENSEN M P. Validity of four pain intensity rating scales[J]. Pain. 2011, 152(10): 2399-2404)
Measured: within 30 days after surgery
Incidence of TDT-related Adverse Events: bleeding
TDT-related adverse events :bleeding
Measured: within 30 days after surgery

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.
