Síndromes post gastrectomía: Clínica, Diagnóstico y Tratamiento.

Abstract

Post-gastrectomy syndromes are described as late postoperative complications, where one of the most common cause is bariatric surgery, as it is currently a common procedure. Gastric surgery modifies gastric anatomy and physiology and this affects the development of these entities. Dumping syndrome and alkaline reflux gastritis are described as the most common, while the development of afferent loop syndrome is not as common today. Dumping syndrome is also called gastric emptying syndrome, the symptoms that present are divided into early ones that are gastrointestinal and vasomotor, and late ones where the development of late hypoglycemia in response to hyperinsulinism stands out. On the other hand, we have the afferent loop syndrome, which is a merely mechanical process due to an excessively long afferent loop, where the symptoms reported by these patients are postprandial abdominal pain, cramps and non-food vomiting that completely relieve pain. And alkaline reflux gastritis is due to chronic exposure of the gastric remnant to bilious and pancreatic substances that induce burning postprandial abdominal pain, associated with nausea and bile vomiting without food content that partially relieves abdominal pain. The identification of these syndromes is important since they deteriorate the quality of life of patients and require proper management by physicians.
