What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
3 years disease-free survival
Time Frame: 3 years
Disease-free survival is defined as the time from date of surgery to the date of rectal cancer recurrence or metastasis or cancer-related death (locoregional or distant recurrence) .
3 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Pathologic outcomes
Time Frame: 1 week post operatively
Pathologic outcomes are defined as TME quality, negative CRM and negative DRM, length of proximal resection margin (PRM), length of DRM, and the number of retrieved lymph nodes.The TME quality was graded based on the criteria proposed by Nagtegaal et al. as complete, nearly complete, or incomplete.Positive resection margin, including circumferential resection margin (CRM) and distal resection margin (DRM), was defined as the presence of cancer cells within 1 mm from the cut edge.
1 week post operatively
30-day postoperative complications
Time Frame: 1 month within operatively
Thirty-day postoperative complications included any complications occurring within 30 days after surgery. Postoperative complications were graded according to the Clavien-Dindo classification. Severe complications were defined as Clavien-Dindo III-V.
1 month within operatively
30-day postoperative mortality
Time Frame: 30 days post operatively
Thirty-day operative mortality is defined as deaths occurring from any cause during the first 30 postoperative days.
30 days post operatively
Overall survival
Time Frame: 3 and 5 years post operatively
Overall survival is defined as the time from date of surgery to date of death from any cause.
3 and 5 years post operatively
Locoregional recurrence rate
Time Frame: 3 and 5 years post operatively
Locoregional recurrence was defined as the presence of any anastomotic, pelvic or perineal tumour documented by clinical and/or pathological examination.
3 and 5 years post operatively

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Operative time
Time Frame: Day 1
Operative time is defined as the time from skin incision to the completion of skin suture.
Day 1
Conversion to Open Surgery
Time Frame: Day 1
The conversion is defined as any part of the mesorectal dissection using the traditional open surgery. The surgeon decided the conversion after considering patient safety, technical difficulties, and relevant conditions influencing the completion of TME.
Day 1
Estimated blood loss
Time Frame: Day 1
Estimated blood loss will be measured according to the suction and the weight of wet gauze, and then minus the irrigation.
Day 1
Length of hospital stay
Time Frame: from the completion of the surgery till discharge from hospital
Duration of hospital stay measured from the day of surgery until the day of discharge from hospital.
from the completion of the surgery till discharge from hospital
Patient self-reported bladder and sexual function
Time Frame: at postoperative 3,6 and 12 months
Patient self-reported bladder and sexual function as assessed by the International Prostatic Symptom Score(I-PSS©) for male and female bladder function and the International Index of Erectile Function (IIEF) Female Sexual Function Index(FSFI©) for sexual function.
at postoperative 3,6 and 12 months
Health related quality of life
Time Frame: at postoperative 3,6 and 12 months

at postoperative 3,6 and 12 months

Primary Completion (ANTICIPATED)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
