Resultados de la manometría del cuerpo esofágico y del asa de yeyuno en pacientes operados por cáncer gástrico con gastrectomía total 5 años después de la cirugía

Abstract

IntroductionThe most preferred technique to reconstruct the intestinal transit after total gastrectomy for gastric cancer is the Roux-en-Y esophagus-gastrostomy which prevents the reflux of alkaline intestinal juice. The purpose of this study was to analyze the esophageal motility and the motility of the jejunal loop in patients subjected to total gastrectomy. Patients and methodA prospective sample of 17 total gastrectomy patients operated on 5 years before was studied using high resolution esophageal manometry including the first 7cm of the jejunal loop. ResultsManometry results showed normal esophageal body motility with the exception of the maximum intrabolus pressure that was elevated in all patients. The jejunal loop motility was disordered and ineffective. ConclusionsEsophageal body motility was normal 5 years after the surgical procedure. However, maximum intrabolus pressure was elevated and the most plausible reason would be the jejunal loop that exerts resistance to the bolus passage due to its ineffective motility. However, this fact does not have a significant clinical impact.
