Gastrectomy, stomach, duodenum, esophagus empty into the intestinal fluid anti-caused inflammation of the esophagus. In particular, most of total gastrectomy and proximal gastrectomy reflux esophagitis caused great suffering to patients.
Pathophysiology of gastric cancer after surgery – reflux esophagitis (1) pathogenesis: the main two, that is, anti-digestive juice into the esophagus and esophageal reflux liquid in the discharge delay, the former as the basic factor. The main reasons causing total gastrectomy or proximal gastrectomy, resection of the lower esophageal sphincter responsible for the door, chest muscle legs, chest muscle esophageal ligaments, responsible for such door notch disappeared, resulting in significantly lower esophageal pressure, the formation of reflux .
Esophageal fluid discharge delay and smooth the whole gastrointestinal tract is the same. Distal subtotal gastrectomy, line-style building completed the surgery, the door can notch angle Select passivation oblique muscle damage to the stomach, the stomach bubble changes, combined with resection of gastrin secretion in the distal stomach was significantly decreased lower esophageal sphincter pressure drop , resulting in esophageal cleft Temple. Therefore, distal subtotal gastrectomy leaves, can also be found reflux esophagitis.
Gastric cancer after surgery pathophysiology – reflux esophagitis (2) preventive measures: total gastrectomy or proximal gastrectomy surgical reconstruction of the line of jejunal interposition operation, and anastomotic esophageal side of the remnant stomach and duodenum or asked from anastomotic side should 25_30Cill. Proximal gastric resection, such as esophageal anastomosis, the best blocking gastric stump, gastric remnant esophageal end to side anastomosis, the anastomotic suture parties mentioned in the remnant stomach on the posterior wall of the esophagus to form a "human responsibility door notch."
Pathophysiology of gastric cancer after surgery – reflux esophagitis, the side most of gastrectomy, BI-style redevelopment, the duodenum should be fully free rod, the World stomach, duodenum notch after the doors are still capable of preservation responsibility. If patients have a habit of constipation, the cause should be removed, so that stool.
