SURGICAL TREATMENT OF SEVERE OBESITY IN TEENS: LATE RESULTS.

BACKGROUND: In children is estimated that the prevalence of overweight and obesity has increased up to five times in developed countries and up to four in developing countries. In Brazil, the proportion of children and adolescents who are overweight also increased from approximately 4.1% to 13.9%. AIM: To evaluate the surgical results of severe obesity in adolescents. METHODS: Retrospective descriptive study of 2737 patients with severe obesity that underwent Roux-en-Y gastric bypass selecting from the total 44 patients with mean age of 18.1 years, 14 males and 30 females, most (37) operated by laparotomy. There was follow-up of 20 patients (45.45%). All were followed preoperatively by a multidisciplinary team and had indication confirmed for surgical unanimous approval of all team members. RESULTS: Among the 20 adolescent, 14 were female. From five teenagers using anti-hypertension or hypoglycemic drugs before surgery, four (80%) had drug discontinuation and one (20%) reduced the dose in 50% postoperatively. The average weight loss was 45.4 kg after a mean follow up of 60 months. There were no deaths or severe postoperative complications. Among those who underwent postoperative follow-up with a multidisciplinary team, 18 were with BMI<30. CONCLUSIONS: Adolescents undergoing Roux-en-Y gastric bypass has good response in relation to weight loss and improvement of comorbidities. There was a low rate of complications and no deaths. All patients were satisfied with their personal results.

Racional: Em crianças estima-se que a prevalência de sobrepeso e obesidade aumentou até cinco vezes nos países desenvolvidos e até quatro naqueles em desenvolvimento. No Brasil, a proporção de crianças e adolescentes com excesso de peso também cresceu de aproximadamente 4,1% para 13,9%.Objetivo: Avaliar os resultados cirúrgicos da obesidade severa em pacientes adolescentes.Métodos: Estudo retrospectivo e descritivo de 2737 pacientes portadores de obesidade severa e submetidos à derivação gástrica em Y-de-Roux selecionando deles 44 com idade média de 18,1 anos. Houve seguimento ambulatorial de 20 pacientes (45,45%). Todos foram acompanhados pré-operatoriamente por equipe multidisciplinar e tiveram sua indicação cirúrgica confirmada após a aprovação unânime de todos os membros da equipe.Resultados: Entre os 20 pacientes adolescentes 14 eram mulheres. Cinco do adolescentes em uso de anti-hipertensivos ou hipoglicemiantes antes da operação, quatro (80%) tiveram a suspensão da medicação e um (20%) reduziu a dose em 50% no pós-operatório. A média de perda ponderal foi de 45,4 kg após seguimento médio de 60 meses. Não houve mortalidade no grupo estudado nem complicações operatórias graves. Entre os que realizaram o acompanhamento pós-operatório com equipe multidisciplinar, 18 ficaram com IMC<30.Conclusões: Adolescentes submetidos à derivação gástrica em Y-de-Roux tiveram boa resposta em relação à perda de peso e melhora das comorbidades. Apresentaram baixa taxa de complicações e nenhum óbito. Todos ficaram satisfeitos com os resultados.

Revision surgery for treatment of weight regain after Roux-en-Y gastric bypass.

BACKGROUND: This study aims to evaluate results on revision surgery for weight regain after gastric bypass, based on surgical technique and follow-up. METHODS: This study is a retrospective analysis of 29 patients who presented weight regain on follow-up after more than 5 years, divided into four groups according to revision surgery type: group 1 (n = 9) includes patients who underwent an increase in the length of the alimentary limb to 200 cm; group 2 (n = 13) are patients who underwent an increase in the length of the alimentary limb and placing of a silicon ring; group 3 (n = 2) are patients who underwent an increase in the length of the alimentary limb and gastric plication, and group 4 (n = 5) are patients who underwent gastric plication and placing of a silicon ring. RESULTS: The average preoperative weight before revision surgery was 117.8 kg, and the average postoperative follow-up for revision surgery was 13.7 months. Weight loss after revision surgery was observed in all groups but was greater in patients with longer revisional postoperative follow-up. Patients who underwent placing of a silicon ring presented greater weight loss than those who had had such a band since the original gastric bypass operation. CONCLUSIONS: Data suggest that revision surgery may be a useful tool in achieving weight loss in patients presenting weight regain following gastric bypass, obesity, bariatric surgery, gastric bypass, weight regain, and revision surgery.
