OBJECTIVE: The present study was aimed at evaluating radiological findings of delayed postoperative upper gastrointestinal series in patients submitted to Fobi-Capella surgery. MATERIALS AND METHODS: Radiological studies of 41 patients, six to nine months following the surgery. RESULTS: The following pathological alterations have been found: hiatal hernia (17%), gastroesophageal reflux disease (19.5%) and sliding of the silastic ring (4.8%). Least frequent findings have been the following: enterocutaneous fistula (2.4%), stenosis of the gastric pouch outlet (2.4%), bezoar (2.4%), and non-visualization of the silastic ring caused by its removal due to patient intolerance (2.4%). Anatomical alterations resulting from the surgery have been clearly demonstrated. CONCLUSION: The present study could demonstrate anatomical alterations and complications resulting from Fobi-Capella surgery.

Breast reconstruction using myocutaneous flaps has been widely used in patients undergoing modified radical mastectomy for the treatment of breast cancer with significant improvement in esthetical results, which also helps to improve self-esteem of the patients as it minimizes the feeling of mutilation, without changing disease prognosis. Previously, it was believed that there was no risk of recurrence in the reconstructed breast due to the complete removal of breast tissue. However, histological studies have shown that a small amount of glandular tissue may remain after mastectomy, with a high potential for malignancy. Clinical follow-up of mastectomy patients is recommended as most recurring lesions occur at the flap margins and can be detected by palpation. In addition, the inclusion of mammographic and ultrasound monitoring has been proposed for the follow-up of patients as these methods may contribute to the diagnosis of recurrent lesions before they become palpable.

OBJECTIVE: To identify and classify the radiographic patterns of megaesophagus in Chagas disease, as seen on esophagograms and chest X-rays. MATERIALS AND METHODS: This was a prospective study of 35 patients diagnosed with esophageal disease via manometry. The changes found on esophagograms were stratified according to Rezende's classification, divided into four categories (grades I through IV) determined by the degree of dilatation and impairement of esophageal motility. We subsequently correlated that ranking with the chest X-ray findings: gastric air bubble; air-fluid level; and mediastinal widening. RESULTS: Among the 35 patients, the esophageal disease was classified as grade I in 9 (25.7%), grade II in 3 (8.6%), grade III in 19 (54.3%), and grade IV in 4 (11.4%). None of the patients with grade I esophageal disease showed changes on chest X-rays. In two of the three patients with grade II disease, there was no gastric air-bubble, although there were no other findings in any of the grade II patients. Of the 19 patients with grade III disease, 15 had abnormal findings on X-rays. All four patients with grade IV disease showed abnormalities. CONCLUSION: The use of Rezende's classification is feasible, encompassing findings ranging from the subtle changes that characterize the initial phases of esophageal disease to the complete akinesia seen in dolicomegaesophagus. Chest X-ray findings are more common in patients with advanced stages of the disease and indicate the degree of esophageal involvement in Chagas disease.
