Digestive tract stricture

Introduction There are many causes of gastrointestinal stenosis, such as inflammatory stenosis, postoperative anastomotic stenosis, neoplastic stenosis, dysplasia, dysmotility (cardiac achalasia) and acid-base burns. Clinically, the above digestive tract stenosis is the most common, so it often causes symptoms of dysphagia. In severe cases, it cannot be eaten. The treatment of the water sac, the balloon, the expansion of the Shah's probe or the placement of a metal stent can relieve the stenosis and ease the difficulty of eating.

Cause

(1) The causes of digestive tract stenosis are divided into benign lesions and malignant lesions, common causes

Benign cause

(1) Inflammatory stenosis.

(2) Physical and chemical factors.

(3) Anastomotic stenosis in digestive tract surgery.

(4) stenosis after endoscopic treatment.

(5) Stenosis after radiation therapy.

(6) Digestive tract motility disorders.

(7) Congenital diseases.

(8) Other web diseases, Schatzki's disease.

2. Malignant factors

Esophageal cancer, drug cancer, stomach cancer, pancreatic head cancer, colorectal cancer, etc.

Difficulty swallowing, severe cases can not eat. Digestive endoscopy can make a narrow lesion.

(1) inflammatory stenosis: reflux esophagitis, infectious esophagitis (such as mold, tuberculosis), anastomotic stomatitis after esophagectomy, formation of pyloric ulcer fatigue, short duodenal ulcer near the pyloric tube, Inflammatory bowel disease, intestinal tuberculosis.

(2) Physical and chemical factors: foreign body damage in the digestive tract, burns, acid-alkaline corrosive damage, esophageal foreign body, stones, and external pressure stenosis.

(3) Anastomotic stenosis in digestive tract surgery: postoperative anastomotic fatigue in the stomach (bi-I or Bi-formal), tumor scar after esophageal anastomosis after gastrectomy, shortness after surgery, and colon After the anastomosis with the mark.

(4) stenosis after endoscopic treatment: postoperative glomerular achalasia, esophageal variceal tissue adhesive embolization, postoperative esophageal variceal sclerotherapy.

(5) stenosis after radiotherapy: after radiotherapy in esophageal tumor, postoperative radiotherapy for colorectal cancer, and postoperative pelvic radiotherapy.

(6) Digestive tract motility diseases: achalasia, diffuse esophageal fistula.

(7) Congenital diseases: esophageal management, congenital esophageal insufficiency.

(8) Other web diseases, Schatzki's disease.

(9) Esophageal cancer, Zimen cancer, gastric cancer, pancreatic head cancer, colorectal cancer, etc.

Difficulty swallowing, severe cases can not eat.

Differential diagnosis

(1) inflammatory stenosis: reflux esophagitis, infectious esophagitis (such as mold, tuberculosis), anastomotic stomatitis after esophagectomy, formation of pyloric ulcer fatigue, short duodenal ulcer near the pyloric tube, Inflammatory bowel disease, intestinal tuberculosis.

(2) Physical and chemical factors: foreign body damage in the digestive tract, burns, acid-alkaline corrosive damage, esophageal foreign body, stones, and external pressure stenosis.

(3) Anastomotic stenosis in digestive tract surgery: postoperative gastric anastomosis (Bi-I or Bi-formal) anastomotic fatigue, neonatal esophageal anastomosis after gastrectomy, shortness after surgery, collateral cataract After the anastomosis with the mark.

(4) stenosis after endoscopic treatment: postoperative glomerular achalasia, esophageal variceal tissue adhesive embolization, postoperative esophageal variceal sclerotherapy.

(5) stenosis after radiotherapy: after radiotherapy in esophageal tumor, postoperative radiotherapy for colorectal cancer, and postoperative pelvic radiotherapy.

(6) Digestive tract motility diseases: achalasia, diffuse esophageal fistula.

(7) Congenital diseases: esophageal management, congenital esophageal insufficiency.

(8) Other web diseases, Schatzki's disease.

(9) Esophageal cancer, Zimen cancer, stomach cancer, pancreatic head cancer, colorectal cancer and other dysphagia, severe cases can not eat. Digestive endoscopy can make a narrow lesion.
