Transhiatal Tunnel Valvuloplasty for Reconstruction Following the Laparoscopic Proximal Gastrectomy

April 8, 2024 updated by: Dong Bing Zhao, Cancer Institute and Hospital, Chinese Academy of Medical Sciences

Transhiatal Tunnel Valvuloplasty for Reconstruction Following the Laparoscopic Proximal Gastrectomy，Phase II Trial

Patients who meet the inclusion criteria will undergo laparoscopic proximal gastric cancer radical surgery, and esophagogastric anastomosis will be performed using the ThTV method.

Review the surgical video and record the time for making the extracorporeal muscle flap, tunnel passage time, and anastomosis time. The production time of the muscle flap is based on the electric knife incision of the muscle flap as the starting point, and successfully penetrating the muscle flap as the endpoint. The tunnel passes through time, pulling the residual end of the esophagus, and starting to pass through the gastric muscle flap tunnel as the time starting point. The complete placement of the gastric tube into the lower mediastinum is used as the time endpoint. The anastomosis time is calculated from the first needle of suturing the residual stomach and the posterior wall of the esophagus until the end of the plasma flap suturing. Record perioperative indicators such as surgical time, bleeding volume, and postoperative hospital stay. The definition of anastomotic stenosis is that in gastroscopy, those who cannot pass through the anastomotic site with ultra-fine endoscopy are judged as anastomotic stenosis.

Postoperative pathology was performed using the 8th edition AJCC staging. Follow up every three months after surgery, including blood tests, liver and kidney function, and tumor markers. According to the situation, choose gastroscopy, upper gastrointestinal imaging, and chest abdominal pelvic enhanced CT. Evaluate postoperative reflux symptoms such as heartburn and sternal pain using the Visick grading system. Gastroscopy Los Angeles grading was used to evaluate postoperative reflux esophagitis.

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.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Confirmed by gastroscopy pathological biopsy and imaging examination as early adenocarcinoma of the upper part of the stomach or adenocarcinoma of the esophageal gastric junction;
  2. Tumor diameter<4cm, with no distant metastasis;
  3. Clinical staging T1-3N0-1M0;
  4. On the basis of proximal gastrectomy, 50% of the gastric volume can still be retained;
  5. ECOG-PS status score 0-1 points (Eastern Cooperative Oncology Group).

Exclusion Criteria:

  1. Patients undergoing preoperative neoadjuvant chemotherapy;
  2. Patients with severe cardiovascular and pulmonary diseases who cannot tolerate laparoscopic surgery;
  3. Incomplete clinical data.

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: ThTV（the Transhiatal Tunnel Valvuloplasty technique group）
Patients who meet the inclusion criteria will undergo ThTV anastomosis after proximal gastrectomy
Procedure: the Transhiatal Tunnel Valvuloplasty technique
The ThTV esophagogastrostomy procedure involved placing a lengthy gastric tube into the lower mediastinum, firmly bound to the esophagus.

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
The incidence of postoperative reflux esophagitis
Time Frame: 1 year
postoperative reflux
1 year

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
the incidence of postoperative anastomotic fistula
Time Frame: 1 year
Postoperative anastomotic fistula
1 year
the incidence of anastomotic stenosis
Time Frame: 1 year
postoperative anastomotic stenosis
