RESUMO
BACKGROUND/AIMS: The aim of this prospective study was to characterize gastric myoelectrical activity in patients with Roux-en-Y reconstruction after previous Billroth gastrectomy. METHODOLOGY: Thirteen patients entered the study (6 men and 7 women, aged 35-57). The mean time from Roux-en-Y reconstruction to electrogastrography (EGG) recording was 5 years. Surface cutaneous EGG was recorded using a Digitrapper EGG in the morning both fasting and after a standard solid test meal. All patients assessed their dyspeptic symptoms at the time of EGG in a semi-quantitative subjective scale. RESULTS: EGG was abnormal in all studied patients (but one postprandial recording). Dyspepsia was not meal-related and was not more severe in Helicobacter pylori positive patients. There was a significant negative correlation between time from Roux-en-Y reconstruction to EGG recording and bradygastria percent activity, both fasted and postprandial (r = -0.576; p = 0.0022). There was an inverse trend between severity of dyspepsia and normal slow-wave rhythm percent activity. Older patients tended to have more severe dyspepsia. CONCLUSIONS: The results of this study suggest that abnormal EGG recording is associated with dyspepsia in patients after Roux-en-Y reconstruction.

BACKGROUND/AIMS: The prognosis of inoperable carcinomas of esophagus is poor, and therapeutic efforts are generally limited to palliation. The aim of this study was to retrospectively evaluate the effectiveness of intraluminal high dose rate brachytherapy in the palliative treatment of tumorous esophageal stenoses. METHODOLOGY: Between February 1997 and July 2002 intraluminal brachytherapy was performed in 19 patients with inoperable esophageal carcinoma (squamous cell carcinoma in 14 cases and adenocarcinoma in 5 cases). All patients had dysphagia at presentation. Brachytherapy was performed using high dose rate afterloading system. RESULTS: Dysphagia was improved in all patients. The mean survival was 248 days. No mechanical complications were observed during introduction of the applicator. CONCLUSIONS: Our experience indicates that intraluminal brachytherapy is an effective and safe method of palliation of dysphagia caused by malignant esophageal stenosis.
