Official title
Comparison of Gastroesophageal Reflux and Quality of Life Between Double-tract and Tubular Gastric Anastomosis in Proximal Gastric Cancer Patients
Overview
This study includes patients diagnosed with proximal gastric cancer (Siewert type II/III, cT1-3N0-1M0) across six tertiary hospitals, who underwent either double-tract reconstruction (DTR) or tubular gastric anastomosis (TGA). Participants were divided into two groups based on the surgical procedure. We conducted a comparative analysis of postoperative outcomes by evaluating electronic medical records, postoperative gastroscopy, 24-hour esophageal pH monitoring, and relevant rating scales.
Interventions
- Procedure Double-tract reconstruction
Patients underwent double-tract reconstruction after radical proximal gastrectomy
Primary outcome measures
- Incidence of postoperative reflux esophagitis [Time frame: 6 month after surgery]
- Severity of reflux esophagitis [Time frame: 6 month after surgery]
Secondary outcome measures (1)
- Postoperative nutritional recovery [Time frame: 1 year after surgery]
Eligibility criteria
Inclusion criteria
- Pathologically confirmed gastric adenocarcinoma by biopsy
- Carcinoma of the upper gastric body or Siewert type II/III adenocarcinoma of the esophagogastric junction (AEG), with a clinical stage of cT1-3N0-1M0
- Age 18-75 years, with a performance status (PS) score of 0-2
- Candidates for planned surgical resection, eligible for either double-tract reconstruction or tubular gastric anastomosis based on preoperative assessment
- No severe dysfunction of vital organs (liver, kidney, heart, lung, or brain), and no severe infection or uncontrolled chronic diseases
Exclusion criteria
- Presence of other malignant tumors or severe chronic diseases (e.g., severe diabetes mellitus, chronic kidney disease, decompensated cirrhosis, etc.)
- Preoperative endoscopic diagnosis of Barrett's esophagus
- Severe preoperative malnutrition (albumin <30 g/L, prealbumin <150 mg/L)
- History of prior upper abdominal surgery, gastrointestinal malformation, or psychiatric disorders
- Preoperative diagnosis of obstructive motor disorders of the cardia (including achalasia spectrum disorders)
- Inability to cooperate with or complete the required postoperative examinations
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
