ABSTRACT

BACKGROUND:

Obesity is one of the world’s greatest health problems. The Roux-en-Y gastric bypass is the gold standard treatment for severe obesity. Surgery in obese patients has an acceptable level of morbidity and mortality. The superobese patient, a subcategory of severe obese patients with a high surgical risk has not yet been analyzed as a group.

METHODS:

A retrospective and prospective cohort study was conducted enrolling 135 patients submitted to Roux-en-Y gastric bypass for treatment of severe obesity at the " Hospital das Clínicas" , Federal University of Pernambuco, Recife, PE, Brazil, between November 1997 and September 2003. The independent variables were possible risk factors of adverse

outcomes:

age, gender, weight, body mass index, diabetes, hypertension, hypercholesterolemia, sleep apnea, cardiopathy/coronariopathy, pneumopathy or any other co-morbidity. The dependent variables were major complications, minor complications and death.

RESULTS:

Diabetes (RR = 1.6 and CI = 1.02-2.40) and sleep apnea (RR = 1.8 and CI = 1.18-2.64) were associated to minor complications. Cardiopathy/coronariopathy were associated with major complications (RR = 5.42 and CI = 1.22-2.40) and death (RR = 16.25 and CI = 3.00-87.95). BMI >55 kg/m² was associated with minor complications (RR = 1.58 and CI = 1.04-2.40), major complications (RR = 3.17 and CI = 1.03-9.80) and death (P = 0.007). After logistic regression, the body mass index >55 kg/m² remained as a strong risk factor of death (OR = 3.6 and CI = 1.05-12.32).

CONCLUSIONS:

The body mass index >55 kg/m² was the main risk factor for severe complications and death. Other risk factors affecting the outcome were diabetes, obstructive sleep apnea and cardiopathy/coronariopathy.
RESUMO
RACIONAL A obesidade é um dos grandes problemas de saúde mundial. A gastroplastia em Y-de-Roux é o padrão-ouro para o tratamento do obeso severo. Cirurgia em pacientes obesos tem aceitáveis índices de morbidade e mortalidade. O paciente superobeso, subgrupo de obesos graves, apresenta risco cirúrgico elevado, ainda não avaliado.

MÉTODOS:

Foi realizado estudo retrospectivo e prospectivo envolvendo 135 pacientes superobesos submetidos a gastroplastia em Y-de-Roux para tratamento de obesidade severa no Hospital das Clínicas da Universidade Federal de Pernambuco, Recife, PE, no período de novembro de 1997 até setembro de 2003. As variáveis independentes foram possíveis fatores de risco idade, sexo, peso, índice de massa corpórea, diabetes, hipertensão, hipercolesterolemia, apnéia do sono, cardiopatia/coronariopatia, pneumopatia ou qualquer outra co-morbidade. As variáveis dependentes foram as complicações graves, complicações leves e óbito.

RESULTADOS:

Diabetes (RR = 1.6 and CI = 1.02-2.40) e apnéia do sono (RR = 1.8 and CI = 1.18-2.64) foram associados a complicações leves. Cardiopatia/coronariopatia foram associadas a complicações graves (RR = 5.42 and CI = 1.22-2.40) e óbito (RR = 16.25 and CI = 3.00-87.95). Índice de massa corporal >55 kg/m² foi associado a complicações leves (RR = 1.58 and CI = 1.04-2.40), complicações graves (RR = 3.17 and CI = 1.03-9.80) e óbito. Após regressão logística, o índice de massa corporal >55 kg/m² permaneceu como forte fator de risco para óbito (OR = 3.6 and CI = 1.05-12.32).

CONCLUSÃO:

O índice de massa corporal >55 kg/m² foi o principal fator de risco para complicações severas e óbito. Outros fatores de risco que afetaram os resultados foram diabetes, apnéia do sono e cardiopatia/coronariopatia.
