Choking sensation (especially with water and liquid diet) and heartburn are the most common complaints of most patients after total gastrectomy, both of which often make postoperative patients miserable and even afraid to eat. The reason for this is that after total gastrectomy, the esophagus and small intestine must be anastomosed to re-establish the digestive tract, but the uncoordinated and inconsistent contraction and peristalsis of the two make patients choke when eating, often especially when drinking water or eating liquid food; in addition, total gastrectomy makes the body lose the two natural anti-reflux barriers of the cardia and pylorus, and the small intestine retrograde peristalsis makes the corrosive digestive fluid containing bile and pancreatic juice enter the esophagus. The regurgitation of digestive juices containing bile and pancreatic juices into the esophagus stimulates the esophageal mucosa and causes heartburn. Therefore, patients after total gastrectomy can ease the symptoms through appropriate dietary regulation, which should be noted as follows: drink water and eat liquid food in small amounts and swallow slowly, avoid swallowing large mouthfuls, avoid too cold and irritating food; keep sitting, slope lying or walking for 20 to 30 minutes after meals, avoid flat lying position after meals; when resting and sleeping, if conditions allow, take the head high about 30 degrees slope position, avoid When resting or sleeping, if possible, you can adopt a head high slope position of about 30 degrees, but not a flat position; you can take some pro-intestinal dynamics drugs to reduce small intestine retrograde peristalsis.
