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.
headings -Obesity. Body mass index. Gastroplasty.abstRact -Background -Vertical gastrectomy is an option to morbid obesity treatment.Removing a relevant part of the stomach's great curvature, a gastric tube is created with low volumetric capacity, giving to the operation the restrictive characteristic. Aim -To evaluate the patients submitted to vertical gastrectomy regarding gender, age, body mass index, associated comorbidities, time of hospitalization and evolution on the early postoperative period. Methods: This was a descriptive and retrospective study that analyzed the medical records of 114 morbidly obese patients submitted to vertical gastrectomy. Results: A hundred and seven (93,8%) of the patients were male and the average age was 38 years old. The body mass index was 45,9 kg/m 2 . About the time of hospitalization, there was a minimum of 3 and maximum of 48 days. The main comorbidity was systemic arterial hypertension (63%). About the evolution after the surgery, 24 patients (21%) needed intensive care and four patients died (3,5%). Conclusions -Vertical gastrectomy constitutes a safe and effective method to the weight loss on morbid obeses, being a surgical technique with low morbimortality and good immediate surgical results.Resumo -Racional -A gastrectomia vertical constitui-se em uma das opções de tratamento para a obesidade mórbida. Com a remoção de parte relevante da grande curvatura gástrica, cria-se um estômago tubular com pequena capacidade volumétrica, dando a característica restritiva à operação. Objetivos -Avaliar os pacientes submetidos à gastrectomia vertical quanto ao gênero, idade, índice de massa corporal, co-morbidades associadas, tempo de internamento e evolução pós-operatória a curto prazo. Métodos -Realizou-se um estudo descritivo e retrospectivo em que foram analisados os prontuários de 114 pacientes obesos mórbidos submetidos à gastrectomia vertical. Resultados -Dos 114 pacientes, 107 (93,8%) eram do gênero masculino, sendo que a idade média foi de 38 anos (19 a 55). O índice de massa corporal médio foi de 45,9 kg/m 2 (35 a 65). O tempo de internamento teve um mínimo de 3 e máximo de 48 dias. A principal co-morbidade associada foi a hipertensão arterial sistêmica (63%). Como evolução pós-operatória, 24 pacientes (21%) necessitaram de cuidados em unidade de terapia intensiva e houve um total de quatro óbitos (3,5%). Conclusões -A gastrectomia vertical constitui-se em método seguro e eficaz para perda de peso em obesos mórbidos, sendo uma técnica cirúrgica com baixa morbimortalidade e bons resultados cirúrgicos imediatos. correspondência:Alcides José Branco Filho,
Gastric plication associated with fundoplication was effective in treating reflux disease with surgical indication and for weight loss in obese patients. Appetite control occurs, but not due to ghrelin, because no significant decrease of its plasmatic levels was observed.
-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.
OBJETIVO: Avaliar a cicatrização da ferida incisional da parede abdominal de ratos hepatectomizados quanto à concentração de colágeno, reação inflamatória e angiogênese. MÉTODOS: Utilizaram-se 48 ratos distribuídos aleatoriamente para laparotomia com e sem hepatectomia. As cicatrizes foram estudadas no 3º, 7º e 14º dia de pós-operatório. Analisou-se a densidade do colágeno por método histoquímico e a angiogênese por método imunohistoquímico. RESULTADOS: A análise do colágeno total mostrou menor concentração no plano da pele e da tela subcutânea, nas cicatrizes abdominais do grupo experimento (p3=0,011; p7=0,004 e p14=0,008). A densidade de colágeno I foi inferior no grupo hepatectomizado, principalmente no 3º dia, tanto na pele e tela subcutânea (p=0,038) quanto no plano aponeurótico (p=0,026). Houve menor concentração de colágeno III nos dois planos estudados, embora não significante. A resposta inflamatória foi semelhante em todos os tempos, nos dois grupos. Verificou-se que a angiogênese desenvolveu-se mais precocemente no grupo controle (p3=0,005 e p7=0,012) e mais tardiamente no grupo experimento (p14=0,048). CONCLUSÃO: A hepatectomia leva ao atraso do processo cicatricial, interferindo na síntese do colágeno e na angiogênese.
