Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Urinary and sexual dysfunction are recognized complications of rectal cancer surgery in men. This study compared robot-assisted total mesorectal excision (RTME) and laparoscopic total mesorectal excision(LTME) with regard to these functional outcomes.Sphincter- preservation outcomes for low rectal cancer was observed as well.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Robot-assisted total mesorectal excision
Robot-assisted total mesorectal excision (RTME) for rectal cancer. Two different RTME procedures were chose to personalized patients. Generally, when the tumor located within 5-15cm from the anal verge, low anterior resection (LAR) was employed, and tumor located below 5cm, abdominoperineal resection (APR) was applied usually.
Procedure: robot-assisted total mesorectal excision
The Da Vinci Surgical System may help to protect subtle anatomical structure and provide more functional protection when compared to laparoscopic surgery. This study aimed to compare RTME and laparoscopic total mesorectal excision (LTME) for rectal cancer with regard to Urinary, sexual function and sphincter- preservation outcomes.
Active Comparator: Laparoscopic total mesorectal excision
Traditional laparoscopic total mesorectal excision (LTME) for rectal cancer was performed. The Urinary, sexual function and sphincter- preservation outcomes were evaluated.
Procedure: laparoscopic total mesorectal excision
Traditional laparoscopic total mesorectal excision (LTME) for rectal cancer.

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
Time Frame
Incidence of sexual and urinary dysfunction
Time Frame: One years after surgery
One years after surgery

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
disease-free survival(DFS )
Time Frame: 3 years disease-free survival
DFS was defined as from the date of randomization to the date of tumor recurrence or death from any cause
3 years disease-free survival
Anus preservation rate
Time Frame: One years after surgery
One years after surgery

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.
