What is a disease of the digestive system
Digestive system diseases include diseases of the esophagus, stomach, intestines, liver, gallbladder, pancreas, and organs such as the peritoneum, mesentery, and omentum. Digestive diseases are common diseases. In China, the mortality of gastric cancer and liver cancer ranks second and third in the ranking of malignant tumor mortality, respectively. In recent years, the prevalence of colorectal cancer and pancreatic cancer has increased significantly. Peptic ulcer is one of the most common digestive diseases. In recent years, the number of doctors may have decreased due to the popularization of Helicobacter pylori eradication and lower relapse rate. Chronic viral hepatitis B and post-hepatitis cirrhosis have been quite common in China. Alcoholic liver disease and alcoholic cirrhosis are quite common in Western countries, and in recent years, it has also gradually increased in China. With the development of society, the disease spectrum in our country is also changing. Gastroesophageal reflux disease and functional gastrointestinal disease, which have not received much attention in our country in the past, have attracted great attention in the field of gastroenterology in China in recent years. Inflammatory bowel disease was a common disease in western countries in the past, and it is rare in China, but in recent years, reports in China have been increasing. Investigations in recent years have shown that non-alcoholic fatty liver disease has become one of the common chronic liver diseases in China.
Next, let 0010010 #39;s understand the examination method of digestive system diseases.
Common endoscopy methods for digestive system diseases
Gastroscopy: The electronic gastroscopy uses a microelectronic camera system with clear images, high resolution, and video storage capabilities. The role of gastroscopy is mainly used for diagnosis and treatment. Due to the direct diagnosis of gastroscopy and the ability to perform pathological biopsy, it can diagnose all esophageal, gastric, and duodenal bulb lesions in a few calls.
Colonoscopy: those with blood in the stool, chronic diarrhea or long-term constipation, those with a clear diagnosis of abdominal mass, those with anemia and occult blood (), those with weight loss and suspected colonic disease, those with follow-up after colon cancer surgery, X-ray barium enema suspected of having colon Patients with disease; those with colorectal polyps and other diseases requiring colonoscopy.
Enteroscopy: mainly used for small intestinal lesions. At present, there are two types of push-type electronic enteroscopy and double-balloon electronic enteroscopy. The former inspection range: from the descending part of the duodenum to about 1/2 of the jejunum, and the double balloon enteroscopy can check all the jejunum and ileum, and the inspection time takes about 2-3 hours. Clinically, unexplained abdominal pain, diarrhea, and mid-abdominal masses with unexplained periumbilical causes are unclear. X-ray small intestine angiography is suspected of ileum disease.
Duodenoscope: mainly used for the examination and treatment of common bile duct and pancreatic diseases.
Capsule endoscope: It was developed by Israeli scientists in August 2000. It consists of a miniature camera and a transmitter. The capsule size is 26 * 11 mm and the weight is 3.7 g. It is a disposable item. After swallowing from the oral cavity, the images of the capsules reaching different parts are sent to the wireless receiver tied to the waist of the patient by gastrointestinal peristalsis.The storage and analysis of the computer can clearly see the images of the stomach, small intestine and total colon. . Because the small intestine is a relatively blind area for endoscopy, capsule endoscopy is of the greatest significance for the diagnosis of small intestinal lesions. At present, a few large domestic hospitals have been launched. Because the cost of examination is expensive, it is necessary to strictly grasp the indications. Whether the general patient needs to be examined should be determined by an experienced digestion expert.
Endoscopic ultrasound: also called endoscopic ultrasound. The miniature high-frequency ultrasound probe is placed at the top of the endoscope. After the endoscope is inserted into the digestive lumen, the morphological structure and lesion images of the mucosal surface in the cavity are directly observed through the endoscope. The wall hierarchy, the origin of the lesion and the extent of tumor infiltration, as well as the surrounding organ tissue structure and lesion images, are an organic combination of endoscopy and ultrasound technology, opening a new way for the diagnosis of gastrointestinal diseases.
How to choose the endoscopy method for digestive system diseases should be combined with the actual situation.
