Laparoscopic anti-reflux surgery is a kind of functional reconstructive surgery, and there are many factors that affect its efficacy besides the surgical operation technique. For example, changes in postoperative dietary habits, changes in lifestyle, individual patient factors, gastrointestinal function, etc., among which changes in dietary habits are more important. Since swelling will occur in the lower esophageal surgical area after laparoscopic anti-reflux surgery, and local adhesions and scar formation will occur later, we need to provide certain guidance on the diet of patients in different periods. 1. The edema in the operated area is most serious in 1 to 3 days after surgery, but because the patients have less food, insufficient energy intake and stronger hunger, some patients will take the initiative to eat semi-liquid, while eating semi-liquid too early will undoubtedly stimulate the inflammation of the lower esophagus and make the esophagus overstretched, aggravating edema; at the same time, the swelling of the operated area of the lower esophagus makes the passage of food obstructed, producing a more serious feeling of swallowing obstruction and aggravating the psychological pressure of patients. Therefore, patients need to be instructed to eat only clear fluids for 1 to 3 days after surgery, while intravenous fluids are supplemented to maintain energy balance. 2.The patient can gradually return to a semi-liquid diet within 1 week after surgery, but it is necessary to slow down the rhythm to return to a normal diet structure, and it is recommended to remain on a semi-liquid diet within 1 month, and return to a normal diet in about 2 to 3 months. 3.For patients with swallowing obstruction, they need to be instructed to change their dietary habits and diet structure to reduce the feeling of swallowing obstruction, and the reasonable suggestion is to eat less and more meals, slow down the speed of eating, and reduce the intake of hard and sticky food, after 2-3 months, the symptoms can gradually disappear. If the symptoms are not relieved by dietary guidance and persistent dysphagia gradually appears, upper gastrointestinal imaging should be performed to clarify the esophageal movement and contrast emptying, and gastroscopic esophageal dilatation treatment is feasible after excluding factors such as sliding of live flap and peresophageal hernia formation.
