Diagnóstico y tratamiento del déficit de hierro, con o sin anemia, pre y poscirugía bariátrica / Diagnosis and treatment of iron deficiency, with or without anemia, before and after bariatric surgery

La cirugía bariátrica es una modalidad terapéutica para la obesidad grave que se utiliza cada vez con más frecuencia, y permite que el paciente consiga una pérdida de peso mantenida en el tiempo y una resolución o mejoría de la mayor parte de las enfermedades asociadas. Una de las principales complicaciones a medio y a largo plazo es el déficit de hierro y la anemia ferropénica, que puede afectar hasta al 50% de los casos, y deteriora de manera importante la calidad de vida del paciente. Estas alteraciones pueden estar presentes desde el preoperatorio. El objetivo de la presente revisión es elaborar unos esquemas de diagnóstico y tratamiento del déficit de hierro y la anemia ferropénica en el pre y postoperatorio de la cirugía bariátrica (AU)

Bariatric surgery (BS) is an increasingly used therapeutic option for severe obesity which allows patients to achieve sustained weight loss over time and resolution or improvement in most associated pathological conditions. Major mid- and long-term complications of BS include iron deficiency and iron-deficient anemia, which may occur in up to 50% of cases and significantly impair patient quality of life. These changes may be present before surgery. The aim of this review was to prepare schemes for diagnosis and treatment of iron deficiency and iron-deficient anemia before and after bariatric surgery (AU)

Criteria for the request of preoperative tests among oral and maxillofacial surgeons.

OBJECTIVE: The aim of this study was to analyze the criteria employed for the requesting of preoperative tests among maxillofacial surgeons. MATERIALS AND METHODS: Thirty maxillofacial surgeons working in Aracaju (Brazil) received a questionnaire to fill out. The study inquired about the practice of requesting preoperative tests for healthy patients scheduled to undergo elective surgery. RESULTS: Most of the surgeons interviewed requested tests that are not recommended for the case in question. The highest frequency of requests was a complete blood count, coagulation test, blood glucose test and chest radiograph. CONCLUSION: The absence of strict rules for the requesting of preoperative tests causes uncertainty and a lack of criteria regarding pre-surgical conduct. It was not possible to clearly define the criteria used by surgeons for requesting such tests, as the clinical characteristics of the hypothetical case presented suggest a smaller number of tests.
