Billroth II With Braun Anastomosis After Radical Distal Gastrectomy for Gastric Cancer

January 18, 2024 updated by: Bo Zhang, MD, Sichuan University

Billroth II With Braun Anastomosis Versus Billroth II Anastomosis After Radical Distal Gastrectomy With D2 Lymphadenectomy for Gastric Cancer: a Randomized Controlled Trial

The primary aim of this trial is to rigorously evaluate the comparative benefits and potential risks associated with Billroth II reconstruction with Braun anastomosis versus Billroth II reconstruction alone following distal gastrectomy with D2 lymphadenectomy in patients diagnosed with gastric cancer. This assessment focuses on delineating the therapeutic efficacy, safety profile, and overall clinical outcomes of these two surgical approaches in treating this condition.

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

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.

Contacts and Locations

This section provides the contact details for those conducting the study, and information on where this study is being conducted.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

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

Experimental: Billroth II with Braun Reconstruction
Procedure: Billroth II reconstruction
Billroth II reconstruction, in which a loop of jejunum is mobilized and anastomosed to the gastric remnant
Procedure: Braun Anastomosis
This is an additional surgical connection (anastomosis) created between two parts of the small intestine, specifically between the afferent (incoming) and efferent (outgoing) limbs of the jejunum near the gastrojejunostomy (the new connection between the stomach and small intestine created during a Billroth II procedure).
Active Comparator: Billroth II Reconstruction
Procedure: Billroth II reconstruction
Billroth II reconstruction, in which a loop of jejunum is mobilized and anastomosed to the gastric remnant

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
Incidence of reflux gastritis assessed according to RGB classification
Time Frame: 6 months, 12 months
by endoscopic evaluation
6 months, 12 months

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.
