Achados tomográficos das alterações abdominais pós-operatórias dos pacientes submetidos ao derivação gastrojejunal em Y-de-Roux sem anel

Abstract

Objective: To evaluate by CT scan in patients undergoing laparoscopic Roux-en-Y gastric bypass without a ring for treatment of morbid obesity that looked for medical assistance after the operation. Methods: We studied 40 CT exams from patients attended at the radiology service with the intention to clarify abdominal complains. The patients were in post-bariatric surgical follow-up and were operated in the same hospital. We excluded patients who had undergone bariatric surgery by other surgical techniques, operated by another surgical team and the ones who did not agree with the administration of oral or intravenous iodinated contrast media and exceeding the weight limit of the examination table. Results: The patients were aged from 23 to 70 years, 11 male and 29 female. There were no extra-abdominal changes, and 30 of the 40 patients had CT findings within normal limits. The presence of stenosis at the gastrojejunal anastomosis was found in one patient, internal hernias occurred in five, anastomotic leak in one and the presence of abscess occurred in three of patients. Conclusion: Total abdominal CT failed to inform the cause of the symptoms in 87.5% of patients seeking medical re-evaluation for symptoms of post-operative bariatric surgery.
