Laparoscopic-assisted Distal Gastrectomy and Totally Laparoscopic Distal Gastrectomy for Gastric Cancer

June 28, 2026 updated by: Dazhi Xu, Fudan University

A Multi-center Prospective Randomized Controlled Trial Comparing the Quality of Life Between Laparoscopic-assisted Distal Gastrectomy (LADG) and Totally Laparoscopic Distal Gastrectomy (TLDG) for Gastric Cancer

The aim of this study is comparing the short-term quality of life between laparoscopy-assisted distal gastrectomy and totally laparoscopic distal gastrectomy for gastric cancer.

Study Overview

Status

Status

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

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

Although totally laparoscopic distal gastrectomy (TLDG) and laparoscopic-assisted distal gastrectomy (LADG) are both minimally invasive surgeries for gastric cancer with the same surgical treatment principles, in the former, all surgical processes are performed intracorporeally, while, in the latter, extracorporeal gastro-enteric anastomosis is achieved. Whether the procedural differences between TLDG and LADG affect quality of life （QOL）is still under debate.To evaluate how each laparoscopic surgery affect QOL of patients with gastric cancer, it is necessary to compare the postoperative QOL (scoring by questionnaire) between the patients undergoing TLDG and LADG through a multi-center randomized controlled trial.

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

20 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

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.
