August 11th, 2007 Guage
Premalignant disease and esophageal cancer refers to a certain form of esophageal disorders, is an independent disease. Major :
(1) cardiac spasms : Due to the disease of the esophageal wall myenteric plexus or absence of esophageal disease caused neuromuscular dysfunction. When food into esophageal and gastric cardia relaxation of weakening or not sensitive, it can not enter the food stomach, esophagus caused cavity retention and the mucosa of chronic inflammatory stimulus and esophageal cancer is the relevant factors.
(2) hiatal hernia : esophageal hiatus because of the expansion and increased abdominal pressure, stomach and other abdominal viscera into the mediastinum. Hiatal hernia patients for gastric reflux caused reflux esophagitis and esophageal ulcer, due to the long lead to esophagitis and esophageal stenosis. Hiatal hernia development of cancer, subject to certain time, the incidence rate of 0 32% to 10%.
(3) esophageal diverticulum : diverticulum of the esophagus cancer, were found to pharyngoesophageal diverticulum, but also seen in other parts of the diverticulum. Cancer occurred in the recreation room or diverticula mouth. Diverticulum cancer diverticulum was mainly due to slower esophageal emptying, the food remains stimulate indoor recreation so I diverticulum or chronic inflammation and ulcers, which prompted the cancer occurred.
(4) polyps and esophageal papilloma : yes to the sudden growth of the tumor cavity, relatively rare. Beattie tumor or FNR to the esophageal wall and connected to the relatively slow growth rate, but such cases prone to cancer.
These premalignant disease and esophageal cancer are more closely related. According to literature, their cancer rates vary considerably, with the precancerous disease duration, esophageal emptying obstacle to the extent and by the stimulation of other parts of a certain relationship, but more important is to decide on whether there with the pathological changes, including inflammation, ulcers, narrow, mucosal atrophy. Leukoplakia so.
