Endofaster Robot for Gastroesophageal Submucosal Tumors: A Randomized Controlled Study

2026年6月17日 更新者：The First Affiliated Hospital of Soochow University

Effectiveness and Safety of the Endofaster Surgical Robot System for Precise Dissection of Gastroesophageal Submucosal Tumors: A Single-Center Randomized Controlled Study

In endoscopic treatment for gastric submucosal tumors arising from the muscularis propria, does robot-assisted surgery yield a higher serosa preservation rate, shorter operative time and lower complication rates than conventional endoscopic procedures?

描述

Inclusion Criteria:

  1. Aged 18 to 80 years old;
  2. Submucosal tumors originating from the muscularis propria of gastric fundus, highly suspected as gastrointestinal stromal tumor (GIST) confirmed by endoscopic ultrasonography (EUS) and contrast-enhanced computed tomography (CT);
  3. Tumor diameter ranging from 1.0 cm to 3.0 cm;
  4. No active ulcer or bleeding on the lesion surface before operation;
  5. American Society of Anesthesiologists (ASA) physical status class I-III;
  6. Voluntarily signed written informed consent.

Exclusion Criteria:

  1. Tumor adhesion to serosa with unclear interface shown on EUS;
  2. High-risk GIST or distant metastasis indicated by imaging or endoscopy;
  3. History of gastric surgery or radiotherapy;
  4. High bleeding risk including coagulation disorders and patients unable to discontinue anticoagulant medications;
  5. Pregnant or breastfeeding women;
  6. Failure to cooperate with follow-up.

武器和干预

参与者组/臂
干预/治疗
实验性的：RG（Robot group）
1.Marking and mucosal incision.2.Grasp the tumor or its pedicle with the robotic flexible arm, apply continuous and steady traction toward the luminal side to dynamically expose the anatomical space between the tumor capsule and normal muscular layer.3.Perform meticulous dissection along the capsule-muscular layer interface using an ESD knife, and preserve the integrity of the serosa as much as possible.4.En bloc resection and removal of the tumor.5.Verification of serosal integrity: The procedure can be completed only if air/water insufflation test shows negative results. Mucosal defects are closed by standard techniques.
设备：Robot system
After Marking and mucosal incision，Grasp the tumor or its pedicle with the robotic flexible arm, apply continuous and steady traction toward the luminal side to dynamically expose the anatomical space between the tumor capsule and normal muscular layer.
有源比较器：TG（Traditional Group）
The procedures are performed by surgeons of equivalent seniority via conventional endoscopic full-thickness resection (EFTR) or modified endoscopic submucosal dissection (modified ESD). If a safe dissection plane cannot be established, full-thickness incision is conducted followed by closure using over-the-scope clip (OTSC), covered stent or suturing techniques. Leakage is assessed and managed in accordance with standard protocols.
设备：Non-robotic conventional endoscopy
Conventional endoscopy without Robot

Postoperative fever is defined as a body temperature ≥ 37.5 ℃ within 7 days after surgery. All febrile cases during this period are included, including non-infectious absorption fever.
Within 7 days after surgery
Postoperative infection
大体时间：Within 30 days after surgery
Postoperative infection is diagnosed when body temperature reaches ≥ 38.5 ℃, or temperature ≥ 38.0 ℃ persists for more than 3 consecutive days starting from postoperative day 3. Diagnosis shall be confirmed by clinical symptoms, abnormal laboratory inflammatory indicators or positive microbial culture results. Simple absorption fever is excluded.
Within 30 days after surgery
