Abstract:
The authors discuss their experience in the surgical treatment of caustic stenosis in the upper gastrointestinal tract. They present operative solutions using isoperistaltic transverse colonic segment in oesophageal stenosis caused by gastric outlet obstruction, or when these two presented together. Further indications for the above were bronchial or tracheo-oesophageal fistulas and oesophageal perforation. Late adaptation of the colonic grafts were measured by radiokinematography and histochemistry. The overall morbidity was 4.9%. Postoperative salivary fistulas closed spontaneously. Late postoperative complications (13.5%) were treated successfully. The multihaustral motility of the graft prevented the reflux, while the altered mucopolysaccharides of the colonic mucosa prevented the ulcer formation. Orv Hetil. 2019; 160(16): 613-618.

Physiology of the Gastrointestinal System II: Digestion and Absorption
Digestion begins in the mouth, where food undergoes mechanical breakdown by chewing and combines with saliva. Salivary amylase, an enzyme in saliva, starts the breakdown of starches into maltose. The food then travels down the esophagus to the stomach.
In the stomach, a...

Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
