What
Under sedation or anesthesia, the lesion is assessed and marked via gastroscopy, often with submucosal injection for elevation first. EMR is often performed by circumferential incision followed by snare resection, while ESD involves layered dissection with specialized instruments until complete resection. Intraoperative hemostasis is performed concurrently, and the specimen is retrieved for pathology. Post-operative monitoring for signs of bleeding and perforation is conducted. The above is general health information and not medical advice; specific details are subject to specialist assessment and hospital protocols.
How
- Assess the lesion using a gastroscope under sedation or anesthesia.
- Perform submucosal injection and circumferential incision or layered dissection.
- Perform intraoperative hemostasis and retrieve the specimen for pathological examination.
- Monitor for signs of bleeding and perforation after surgery.
Recovery
Monitor for abdominal pain, fever, melena, etc. after surgery. Early stages often involve liquid or semi-liquid diets, gradually resuming solid foods. Avoid strenuous exercise and heavy physical activity in the short term. Follow-up visits are used for wound assessment and pathological interpretation, followed by decisions on follow-up or additional treatment. Whether air travel and MRI/security checks are permissible depends on whether metal clips are retained and is confirmed by the doctor.
- Monitor symptoms such as abdominal pain, fever, and melena.
- Eat liquids early and gradually resume solid foods.
- Determine the follow-up time and security check according to the doctor's advice.
FAQ
Will it recur after surgery?
New or residual lesions may still occur, and endoscopic follow-up is required as directed by the doctor; the follow-up interval is determined by the pathological results and individual risk.
Is general anesthesia required?
Sedation or general anesthesia can be selected based on lesion size, patient tolerance, and hospital procedures; the method of anesthesia is jointly assessed by the anesthesia and endoscopy teams.
How soon can I return to work or fly?
It is recommended to arrange this after the follow-up evaluation is stable; if metal clips are retained, the doctor will explain travel and security check precautions and carry the report with you.
How is the post-operative diet arranged?
Usually starting with liquid or semi-liquid diets, gradually transitioning to a normal diet; avoid spicy, rough, and alcoholic foods, and follow the doctor's instructions.
What are the differences between EMR and ESD?
EMR is mostly used for smaller or suitable for piecemeal lesions; ESD is more commonly used in the pursuit of en bloc resection and accurate staging. The choice depends on lesion characteristics and assessment.
How are pathology reports and follow-up conducted?
Pathology is issued uniformly by the hospital, and the doctor will develop a follow-up and additional treatment plan based on the results; the specific nodes are determined by individual recovery and assessment.
Does the fee include pathology and hospitalization?
Usually includes the surgery itself, basic monitoring, and pathology, etc., but the contents of different hospital packages vary; subject to the official quotation and list.
How are the risks of perforation and bleeding managed?
Injection, clipping, and coagulation can be used to control bleeding during surgery; post-operative vigilance for abdominal pain, fever, or melena is required. If these occur, seek medical attention promptly.
