纳入标准: |
1. 各种原因导致的胃流出道梗阻患者;术前常规胃镜检查时根据胃内可见度进行评分,胃准备不充分者定义为胃内可见度评分≥3分。胃内可见度评分如下: 准备质量:充分 得分:0 镜下所见:整个黏膜清晰,无液体残留 得分:1 镜下所见:清澈的液体残留物 得分:2 镜下所见:评估区域<25%的能见度降低(混浊液体、粘液、气泡、食物残渣等潴留) 准备质量:不充分 得分:3 镜下所见:评估区域25-50%的能见度降低(混浊液体、粘液、气泡、食物残渣等潴留) 得分:4 镜下所见:评估区域>50%的能见度降低(混浊液体、粘液、气泡、食物残渣等潴留) 得分:5 镜下所见:评估区域大部分(>75%)的能见度降低(混浊液体、粘液、气泡、食物残渣等潴留、 得分:6 镜下所见:大量的食物残渣、粘液、混浊液潴留导致胃内扩张 2. 需要完成EUS诊疗; 3. 签署临床研究知情同意书。 |

Inclusion criteria |
1. Patients with gastric outlet obstruction (GOO) caused by various factors; preoperative routine endoscopy is scored based on intragastric visibility, and inadequate gastric preparation is defined as an intragastric visibility score of ≥3. The gastric visibility scoring criteria are as follows: Preparation quality: Adequate Score 0 Endoscopic findings: The entire mucosa is clearly visible, with no residual fluid. Score 1 Endoscopic findings: Clear residual fluid is present. Score 2 Endoscopic findings: Visibility is reduced in <25% of the assessed area due to retained turbid fluid, mucus, bubbles, food residue, or other materials. Preparation quality: Inadequate Score 3 Endoscopic findings: Visibility is reduced in 25%–50% of the assessed area due to retained turbid fluid, mucus, bubbles, food residue, or other materials. Score 4 Endoscopic findings: Visibility is reduced in >50% of the assessed area due to retained turbid fluid, mucus, bubbles, food residue, or other materials. Score 5 Endoscopic findings: Visibility is reduced in most of the assessed area (>75%) due to retained turbid fluid, mucus, bubbles, food residue, or other materials. Score 6 Endoscopic findings: Gastric distension caused by a large amount of retained food residue, mucus, and turbid fluid. 2. Patients requiring the completion of endoscopic ultrasound (EUS) diagnosis and treatment; 3. Patients who have signed the clinical study informed consent form. |

Exclusion criteria: |
1. Inability to insert the suction tube due to altered anatomical conditions; 2. Patients unable to tolerate surgery due to concurrent severe coagulation disorders, severe cardiopulmonary disease, or poor general condition; 3. Patients with suspected gastrointestinal perforation; 4. Patients who are uncooperative due to mental illness or severe intellectual disability; 5. Refusal of the patient or their legal guardians to participate in the study; 6. Study participants who have already been enrolled in other clinical studies. |
