NCT06300879

Brief Summary

This is a single-center, open-label, Phase Ib/II study aiming to assess the perioperative safety and postoperative outcomes of a novel surgical technique in treating primary adenocarcinoma located in the upper 1/3 of the stomach or gastroesophageal junction (Siewert II or III). The study will enroll 30 patients who will undergo totally laparoscopic proximal gastrectomy with esophagogastrostomy by fissure technique. Clinical data will be collected to evaluate perioperative safety. Patients will be followed for at least 3 months, during which endoscopy will be performed to analyze occurrences and reasons for anastomotic-related complications. Additionally, the quality of life after surgery will be evaluated by QLQ-C30 and QLQ-STO22.

Outcome Measures

Primary Outcomes (5)

  • Assess intraoperative Perioperative Safety by Duration of surgery.

    Time spent on the whole operation(minutes)

    intraoperative

  • Assess intraoperative Perioperative Safety by Duration of anastomosis.

    Time spent on the anastomosis in minutes

    intraoperative

  • Assess intraoperative Perioperative Safety by blood loss .

    Intraoperative blood loss in milliliters

    intraoperative

  • Postoperative recovery course

    Time to remove the drain tube,flatus, to liquid diet, and soft diet are used to assess the postoperative recovery course, which is a composite outcome measure.

    30 days after the surgery

  • Postoperative TNM staging by Pathological findings .

    AJCC(American Joint Committee on Cancer)-8th TNM staging system will be used to obtain pathology of tumor .

    30 days after the surgery

Secondary Outcomes (4)

  • The incidence of postoperative reflux esophagitis

    3 months after surgery

  • The incidence of postoperative anastomotic stenosis

    3 months after surgery

  • Quality of Life at 3 Months Postoperatively will be assessed by EORTC QLQ-C30

    3 months after surgery

  • Quality of Life at 3 Months Postoperatively will be assessed by EORTC QLQ-STO22 scale

    3 months after surgery

Study Arms (1)

Experimental group

EXPERIMENTAL

Performing totally laparoscopic proximal gastrectomy with esophagogastrostomy by fissure technique

Procedure: Performing totally laparoscopic proximal gastrectomy with esophagogastrostomy by fissure technique

Interventions

Surgical Operation: 1. Gastric Resection Range:Proximal gastrectomy, preserving 2/3 of the distal stomach. 2. Lymph Node Dissection Range:D1+ to D2 lymph node dissection. 3. Anastomosis Method: esophagogastrostomy by fissure technique. 4. Anastomosis Risk Management Plan:For a rupture with a maximum diameter less than or equal to 5mm, repair with 4-0/3-0 absorbable sutures and proceed with the anastomosis.For a rupture with a maximum diameter greater than 5mm or failed anastomosis, resect that part of the remaining stomach, change to proximal gastrectomy, and perform double-channel anastomosis. 5. Surgical Approach:Totally laparoscopic proximal gastrectomy.
