Preoperative factors correlated with post-bariatric surgery weight loss.

Whether preoperative parameters can predict weight loss following bariatric surgery is a matter of debate. We conducted a longitudinal and prospective pilot study on 35 patients that underwent bariatric surgery, with a 12-month follow-up. In the preoperative period, a high HOMA-beta index, lower fasting blood glucose, and lower HbA1c were correlated with a lower BMI at 12 months. Traditional preoperative factors, such as weight and BMI, were correlated with the postoperative BMI values. The presence of well-controlled diabetes may influence weight loss after surgery.

Modificacao do afastador de Bennett-Jones para a cirurgia das vias biliares. / Modification of the Bennett-Jones retractor for bile duct surgery

As dificuldades tecnicas encontradas na cirurgia das vias biliares em pacientes obesos permitiram modificacoes no afastador de Bennett-Jones. As modificacoes introduzidas no referido afastador consistiram na variacao do tamanho das laminas metalicas, segundo o grau de obesidade dos pacientes.Foram estudados 15 pacientes submetidos a colecistectomia, com ou sem coledocostomia onde os autores apresentam sua experiencia con este novo metodo, comentando as indicacoes, os aspectos tecnicos e os resultados obtidos
