Conditions

Proximal Early Gastric Cancer

Brief summary

This study is a multicenter, open-label, prospective, randomized parallel-controlled trial. The purpose is to explore whether the incidence rate of reflux esophagitis (RE) within 12 months after surgery is non-inferior for the DFT group compared to the DTR group.

Detailed description

This study will enroll patients with proximal gastric cancer scheduled to undergo laparoscopic proximal gastrectomy. The patients will be randomly divided into two groups. One group will undergo laparoscopic proximal gastrectomy with double-flap technique (DFT) anastomosis, while the other group will undergo laparoscopic proximal gastrectomy with double-tract reconstruction (DTR). The primary endpoint is the proportion of patients who develop reflux esophagitis within 12 months after surgery. The secondary endpoints include postoperative complications, surgery-related indicators, and postoperative nutritional status.

Interventions

PROCEDUREdouble-flap technique(DFT); double-tract reconstruction(DTR),

DFT (experiment group). Patients receive double flap technique after laparoscopic proximal gastrectomy. DTR (control group). Patients receive double-tract reconstruction after laparoscopic proximal gastrectomy.

Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1; 4. American Society of Anesthesiologists (ASA) classification of I to III; 5. Acceptable for laparoscopic proximal gastrectomy with preoperative examinations (based on endoscopic ultrasound and/or contrast-enhanced computed tomography of the thorax and abdomen) confirming the following oncological features: Primary tumor located in the upper part of the stomach (proximal 1/3 of the stomach) or gastroesophageal junction; Length of esophageal invasion ≤ 1 cm, tumor maximum diameter ≤ 4 cm; Preoperative staging T1-3N0M0 (based on AJCC 8th edition TNM clinical staging); 6. Voluntary signing of informed consent.

Exclusion criteria

Conditions deemed unsuitable for participation in this study by the investigator.

Proportion of patients with reflux esophagitisWithin 12 months after surgeryThe percentage (%) of patients developing postoperative reflux esophagitis after surgery in the two group.

Secondary

MeasureTime frameDescription
Operation timePerioperative periodFrom the beginning of surgery to the end of surgery
Kamikawa anastomosis timePerioperative periodThe time of making the seromuscular flap and the time of esophagogastrostomy were included
intraoperative blood lossPerioperative periodThe operation begins to end the amount of bleeding.
Weight changeWithin 12 months after surgeryCalculated in kilograms
Body Mass Index (BMI)Within 12 months after surgeryweight and height will be combined to report BMI in kg/m\^2
Albumin valueWithin 12 months after surgeryThe concentration of albumin in the blood, expressed in g/L.
Postoperative complicationsWithin 12 months after surgeryEvaluated using the Clavien-Dindo classification to assess the severity of postoperative complications.
Hemoglobin valueWithin 12 months after surgeryThe concentration of Hemoglobin in the blood, expressed in g/L.
Folic acid valueWithin 12 months after surgeryThe concentration of Folic acid value in the blood, expressed in ng/mL.
Vitamin B12 valueWithin 12 months after surgeryThe concentration of Vitamin B12 value in the blood, expressed in uug/L.
Ferritin valueWithin 12 months after surgeryThe concentration of Vitamin B12 value in the blood, expressed in ug/L.
Nutritional risk screening 2002Within 12 months after surgeryThe nutritional status is assessed using the Nutrition Risk Screening 2002 (NRS-2002) scale, with a scoring range of 0 to 7 points. A higher score indicates a worse nutritional status.
Pre albumin valueWithin 12 months after surgeryThe concentration of pre albumin in the blood, expressed in g/L.
