Inclusion criteria
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 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
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.
