BackgroundColonoscopy is the most frequent exam used to evaluate colonic mucosa, allowing the diagnosis and treatment of many diseases. The appropriate bowel preparation is indispensable for the realization of colonoscopy. Therefore, it is necessary the use of laxative medications, preferentially by oral administration.AimTo compare two medications used in bowel preparation in adult patients going to ambulatory colonoscopy and to analyze the patients' profile.MethodsA double-blind prospective study with 200 patients, randomized in two groups: one that received polyethilene glycol and another that received lactulose. The patients answered to questionnaires to data compilation, as tolerance, symptoms and complications related to preparation. Besides, it was also evaluated the prepare efficacy related to the presence of fecal residue.ResultsIntestinal habit alterations and abdominal pain were the main reasons to realize the exams and hypertension was the most prevalent comorbidity. Ten percent of the ones who received lactulose didn't get to finish the preparation and 50% considered the taste "bad, but tolerable". The most common subjective symptom after the medication was nausea, especially after lactulose. During the exam, most of the patients who used lactulose had a "light discomfort" and the ones who used polyethilene glycol considered the discomfort as "tolerable". The quality of the preparation was good in 75%, undependable of the medication that was used.ConclusionPolyethilene glycol was more tolerable when compared to lactulose, without difference on the quality of the preparation.

-Background -Diabetes mellitus type 2 is not infrequently associated with obesity and can be prevented, improved and even reversed with the different types of bariatric operations. Aim -To compare serum glucose levels on pre and postoperative periods in patients undergoing gastroplasty with Capella and gastric sleeve techniques. Method -A descriptive and prospective analysis of serum glucose levels was done on pre and post-operative patients undergoing these operations. Results -Of the 83 patients analyzed, 76 (91.5%) were female. Ages ranged from 21 to 64 years, with average age of 44 years. Seventy-seven (92.7%) underwent gastroplasty (Capella) and six (7.3%) to gastric sleeve. The pre-operative blood glucose ranged from 125 to 500 mg / dL and dropped to 76 to 120 mg / dL in the post-operative period of three months. Of the 77 patients taking medication for diabetes, 57 had metformin 850 to 3500 mg daily, 18 glibenclamide 5 to 10 mg per day and 17 insulin. After three months of operation, 92.2% stopped using drugs for diabetes and 100% of those who remained medicated decreased from more than 65% the dose of the drug, and none remained dependent of insulin treatment. Conclusion -Bariatric surgery is effective method to improve and even reverse type 2 diabetes mellitus. ABCDDV/814RESUMO -Racional -O diabete melito tipo 2 está, com certa frequência, associado à obesidade mórbida e pode ser prevenido, melhorado e até mesmo revertido com as diversas modalidades de operações bariátricas. Objetivos -Comparar as glicemias séricas pré e pós-operatórias dos pacientes submetidos à gastroplastia com as técnicas de Capella e sleeve gástrico. Método -Estudo descritivo e prospectivo com análises das glicemias séricas pré e pós-operatórias de pacientes submetidos à gastroplastia. Resultados -Dos 83 pacientes analisados, 76 (91,5%) eram do sexo feminino. A idade variou de 21 a 64 anos, sendo 44 anos a idade média. Setenta e sete (92,7%) foram submetidos à gastroplastia (Capella) e seis (7,3%) à sleeve gástrico. A glicemia pré-operatória variou de 125 a 500 mg/dL caindo para a variação de 76 a 120 mg/dL no pós-operatório de três meses. Dos 77 pacientes que usavam tratamento medicamentoso para a diabete, 57 tomavam metformina de 850 a 3500 mg por dia, 18 glibenclamida de 5 a 10 mg por dia e 17 insulina. Após 3 meses da operação, 92,2% cessaram o uso de medicamentos para diabete e em 100% dos que permaneceram medicados houve redução de mais de 65% na dose do fármaco, sendo que nenhum permaneceu dependente de insulina no tratamento. Conclusão -A cirurgia bariátrica constitui-se em método eficaz para a melhora e até mesmo reversão do diabete melito tipo 2.
