Pyloric obstruction is divided into edematous pyloric obstruction, scarred pyloric obstruction, pyloric obstruction caused by malignant tumors, and external pressure pyloric obstruction. The treatment of scar pyloric obstruction needs to be decided according to the specific conditions of the patient: 1. If the patient is <60 years old and in good physical condition, it is recommended that the patient take surgical procedures to remove the scar and perform reconstruction of the digestive tract; 2. If the patient is older or has combined cardiopulmonary disease and cannot tolerate surgery, endoscopic stent placement can be considered to ensure the patency of the patient's digestive tract through the expansion of the stent, so that the patient can eat and improve their quality of life.
