May 17, 2015 updated by: wei bo

Compared With Robotic-assisted and Laparoscopic-assisted Gastrectomy for Gastric Cancer on Surgical,Clinical and Oncological Outcomes

The study aims to compare the clinical outcomes between robotic-assisted and laparoscopic-assisted gastrectomy for gastric cancer,and evaluate the the feasibility and safety of robotic gastrectomy. Furthermore, the investigators can explore the patients who are more suitable for robotic gastrectomy.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

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

This is a prospective study lasting 36 months.

Minimally invasive gastrectomy is accepted widely in Asian countries. Laparoscopic-assisted gastrectomy offers improved early postoperative outcomes and improved long-term oncologic outcomes,but it still has its own limitations.The advantages of robotic surgery include a 3D imagine, convenient movements of the robotic arm, no tremor, and ambidextrous capability.

This study therefore aimed to compare the clinical results between robotic-assisted gastrectomy(RAG) using the da Vinci Surgical System and conventional laparoscopic-assisted gastrectomy(LAG) in gastric cancer patients.To evaluate the the feasibility and safety of robotic gastrectomy and explore the patients who are more suitable for robotic gastrectomy.

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.

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.
