[Functional study of intestinal transplants after esophagectomy].

The Authors contribute their experience covering 228 cases of esophagoplasty after esophagectomy for cancer of the esophagus and of the esophagogastric junction, from 1980 to 1989. Thirty four of these patients (24 EGP, 8 EDP, 2 ECP) underwent accurate functional investigation by X-ray, manometry, pH-metry and scintigraphy. The investigation into esophagogastroplasty in particular revealed that the transposed organ is devoid of motor activity and that emptying is therefore achieved by gravity. It was also shown that the entity of the alkaline, acid and mixed-type reflux is linked to the site of the anastomosis: greater proximity of the anastomosis translates into lower involvement. An investigation into esophagojejunoplasty, instead, highlighted normal motor function: no cases presented reflux of the alkaline type. The two cases of colon plasty investigated presented efficient emptying even though manometry could not detect the presence of motor waves of the propulsive type. The authors conclude that, although the jejunum constitutes the best prosthetic element to transpose from the functional point of view, highly inconsistent and precarious vascularization limits the use of this organ to the higher anastomoses only. Therefore the Authors claim that the stomach, despite its tendency to behave as an inert tube, is still the best choice for transpositions following esophagectomy.
