ABSTRACT
All parts of the gastrointestinal tract are accessible for study using nuclear medicine techniques. We have studied the effect of esophageal reconstruction surgery, in different periods of time, after surgical procedure. Oncologic patients (19) were evaluated after esophageal reconstruction surgery with gastric (group II - 14 patients) or colonic tube (group III - 5 patients) and they were compared with 15 healthy volunteers (group I). Gastric emptying was performed in the same subjects using solid food (egg sandwich) labeled with 99mTc-phytate. In emptying gastric studies, the mean (T1/2) of the patients was much faster than those of the control (p<0.05) when 1/3 distal tube was considered as stomach. However, there was no difference between the T1/2 of group II and group III. We concluded that this nuclear medicine method could be useful in the monitoring the surgical reconstruction of the esophagus.

Nas complicaçöes da diabetes mellitus pode estar incluido o comprometimento da inervaçäo esofagiana, levando a distúrbios motores do esôfago, mesmo em fases näo sintomáticas. Tendo em vista a simplicidade e a sensibilidade do método cintilográfico no estudo da motilidade esofagiana, os autores propuseram a comparar o tempo de trânsito esofagiano com radionuclídeo em pacientes portadores de diabetes mellitus e em individuos normais. Foram estudados 33 pacientes diabéticos e 26 controles, sendo divididos em grupo A (dependente de insulina) e B (näo dependentes). O estudo mostrou que as alteraçöes no tempo de trânsito esofagiano predominam nos grupos diabéticos näo dependentes de insulina, näo havendo relaçäo com o tempo de duraçäo da doença. No grupo dependente, as anormalidades encontradas tiveram relaçäo com o tempo de doença
