LAPAROSCOPIC AND LAPAROTOMY BARIATRIC SURGERY IN A PUBLIC HOSPITAL IN BRAZIL: ARE THERE DIFFERENCES IN COSTS AND COMPLICATIONS?

BACKGROUND: Despite its increasing popularity, laparoscopy is not the option for bariatric surgeries performed in the Brazilian public health system. AIMS: To compare laparotomy and laparoscopic access in bariatric surgery, considering aspects such as morbidity, mortality, costs, and length of stay. METHODS: The study included 80 patients who were randomly assigned to perform a Roux-en-Y gastric bypass. They were equally divided in two groups, laparoscopic and laparotomy. The results obtained in the postoperative period were evaluated and compared according to the Ministry of Health protocol, and later, in their outpatient returns. RESULTS: The surgical time was similar in both groups (p=0.240). The costs of laparoscopic surgery proved to be higher, mainly due to staplers and staples. The patients included in the laparotomy group presented higher rates of severe complications, such as incisional hernia (p<0.001). Costs related to social security and management of postoperative complications were higher in the open surgery group (R$ 1,876.00 vs R$ 34,268.91). CONCLUSIONS: The costs related to social security and treatment of complications were substantially lower in laparoscopic access when compared to laparotomy. However, considering the operative procedure itself, the laparotomy remained cheaper. Finally, the length of stay, the rate of complications, and return to labor had more favorable results in the laparoscopic route.

RESUMO RACIONAL: Apesar de sua crescente popularidade, a laparoscopia não é a via de acesso em cirurgias bariátricas realizadas no sistema público de saúde brasileiro. OBJETIVOS: Comparar os acessos laparoscópico e laparotômico em cirurgia bariátrica, considerando aspectos como morbidade, mortalidade, custos e tempo de hospitalização. MÉTODOS: Foram incluídos 80 pacientes candidatos a by-pass gástrico em Y-de-Roux, aleatoriamente divididos em dois grupos, de acordo com a via de acesso. Os resultados obtidos no período pós-operatório foram avaliados e comparados de acordo com o protocolo do Ministério da Saúde, e posteriormente, em seus retornos ambulatoriais. RESULTADOS: O tempo cirúrgico foi semelhante em ambos os grupos (p=0.240). Os custos da cirurgia laparoscópica foram maiores, principalmente devido aos grampeadores e cargas. Contudo, os pacientes designados à via aberta apresentaram maior índice de complicações graves, como hérnia incisional (p<0.001). Desta forma, os custos com o tratamento das complicações e com o seguro social foram maiores neste grupo (R$ 1,876.00 vs R$ 34,268.91). CONCLUSÃO: Os gastos relacionados ao seguro social e ao tratamento de complicações foram substancialmente menores na cirurgia laparoscópica quando comparada à cirurgia aberta. Entretanto, considerando o procedimento operatório em si, a via aberta foi a mais acessível financeiramente. Por fim, o tempo de hospitalização, a taxa de complicações e o tempo de retorno ao trabalho tiveram resultados mais favoráveis na via laparoscópica.

OBJECTIVE: to analyse clinical and epidemiological characteristics, postoperative complications, and weight loss in patients undergoing conventional vertical gastrectomy in a hospital under Brazil's Public Health System (SUS). METHODS: cross-sectional longitudinal retrospective study based on data collection from medical records for variable analysis in patients undergoing open vertical gastrectomy in SUS, from July 2013 to January 2017. RESULTS: we analysed 296 patients operated on during the study period, of which 54% were male. The average age was of 39.9 years ±11.4; the average body mass index (BMI) was of 43.5kg/m² in the preoperative period and of 30.3kg/m² in the postoperative period; and the excess weight loss was of 73.6% (83.24% had an excess weight loss greater than 50%). Preoperative BMI was higher in the group with weight loss below 50%. We observed a 5.4% rate of early complications requiring hospitalization and a 1% mortality rate. CONCLUSION: open vertical gastrectomy is a safe and effective weight loss technique, which can be more performed in SUS. Among the variables evaluated in our work, the previous BMI was the only one related to the postoperative success.

Análise de prevalência e preditores de deficiências nutricionais após gastrectomia vertical / Prevalence analysis and predictors of nutritional deficiencies after sleeve gastrectomy

Objetivo: Avaliar a prevalência de deficiências nutricionais no pós-operatório de gastrectomia vertical (GV) e a influência do uso de multivitamínicos e da perda peso. Materiais e métodos: análise retrospectiva de 190 pacientes submetidos a GV de 2013 a 2017. Foi avaliada uma dosagem sérica de micronutrientes e a relação com a perda de peso. Resultados: dos 190 pacientes, 28,97% apresentavam anemia, 11,22% apresentaram ferritina baixa, deficiências de albumina (2%), zinco (1%), vitamina B12 (4,35%) e a vitamina D (9,78%). Além disso, 34,4% precisou repor vitamina D, 27,2% vitamina B12 e 12,5% ferro. A deficiência de vitamina D foi diretamente relacionada com peso pré-operatório mais elevado(p=0,038). Não houve relação entre o uso de multivitamínicos ou perda de peso e a prevalência das deficiências nutricionais. Conclusões: o peso pré-operatório elevado foi um preditor de deficiência de vitamina D no pós operatório.

Objective: Assess the prevalence of nutritional deficiencies in the postoperative period of sleeve gastrectomy and the influence of multivitamins use and weight loss. Methods: A retrospective and cross-sectional analysis of 190 patients who underwent sleeve gastrectomy from 2013 to 2017. Micronutrients levels were analyzed and compared with weight loss. Results: Anemia was present in 28.97% of the patients, and 11.22% had low ferritin, albumin (2%)and zinc (1%) levels. Regarding vitamin deficiencies, vitamin B12 was low in 4.35% and vitamin D in 9.78%. Besides, 34.4% of the sample required vitamin D supplementation, 27.2% vitamin B12 supplementation, and 12.5% iron supplementation. Vitamin D deficiency was directly related to higher preoperative weight (p = 0.038). There was no link between the use of multivitamins or weight loss and the prevalence of nutritional deficiencies. Conclusions: High preoperative weight was a predictor of postoperative vitamin D deficiency.

Predictors of Success in Bariatric Surgery: the Role of BMI and Pre-operative Comorbidities.

BACKGROUND: This is a retrospective review of 204 patients who underwent bariatric surgery. The impact of weight regain (WR), pre-operative comorbidities and BMI values on the recurrence of comorbidities was evaluated, and an equation was elaborated to estimate BMI at 5 years of bariatric surgery. METHODS: Pre-operative data, after 1 year and after 5 years, was collected from the medical records. Descriptive analyses and bivariate hypothesis tests were performed first, and then, a generalised linear regression model with Tweedie distribution was adjusted. The hit rate and the Kendall coefficient of concordance (Kendall's W) of the equation were calculated. At the end, the Mann-Whitney test was performed between the BMI, WR and the presence of comorbidities, after a post-operative period of 5 years. RESULTS: The adjustment of the model resulted in an equation that estimates the mean value of BMI 5 years after surgery. The hit rate was 82.35% and the value of Kendall's W was 0.85 for the equation. It was found that patients with comorbidities presented a higher median WR (10.13%) and a higher mean BMI (30.09 kg/m2) 5 years after the surgery. CONCLUSIONS: It is concluded that the equation is useful for estimating the mean BMI at 5 years of surgery and that patients with low pre-operative HDL and folic acid levels, with depression and/or anxiety and a higher BMI, have a higher BMI at 5 years of surgery and higher incidence of comorbid return and dissatisfaction with post-operative results.

COMPLICATIONS RELATED TO GASTRIC BYPASS PERFORMED WITH DIFFERENT GASTROJEJUNAL DIAMETERS.

Background: Among the options for surgical treatment of obesity, the most widely used has been the Roux-en-Y gastric bypass. The gastrojejunal anastomosis can be accomplished in two ways: handsewn or using circular and linear stapled. The complications can be divided in early and late. Aim: To compare the incidence of early complications related with the handsewn gastrojejunal anastomosis in gastric bypass using Fouchet catheter with different diameters. Method: The records of 732 consecutive patients who had undergone the bypass were retrospectively analyzed and divided in two groups, group 1 with 12 mm anastomosis (n=374), and group 2 with 15 mm (n=358). Results: The groups showed anastomotic stenosis with rates of 11% and 3.1% respectively, with p=0.05. Other variables related to the anastomosis were also analyzed, but without statistical significance (p>0.05). Conclusion: The diameter of the anastomosis of 15 mm was related with lower incidence of stenosis. It was found that these patients had major bleeding postoperatively and lower surgical site infection, and in none was observed presence of anastomotic leak.

Racional: Entre as opções para o tratamento cirúrgico da obesidade, o mais utilizado é o bypass gástrico em Y-de-Roux. A anastomose gastrojejunal dele pode ser realizada de duas maneiras, manualmente ou utilizando grampeador linear e circular, e as complicações são dividas em precoces e tardias. Objetivo: Comparar a incidência de complicações precoces relacionadas com a confecção manual da anastomose gastrojejunal no bypass gástrico utilizando sonda de Fouchet com calibres diferentes. Métodos: Foi realizada análise retrospectiva transversal com 732 pacientes submetidos ao procedimento, divididos em dois grupos, grupo 1 com anastomose de 12 mm (n=374), e grupo 2 de 15 mm (n=358). Resultados: Os grupos apresentaram taxas de estenose de anastomose de 11% e 3,1% respectivamente, com p=0,05. Outras variáveis relacionadas à anastomose também foram analisadas, porém sem significância estatística (p>0,05). Conclusão: O diâmetro da anastomose de 15 mm esteve relacionado à menor ocorrência de estenoses. Verificou-se, contudo, que estes pacientes apresentaram maior sangramento no pós-operatório e menor infecção de sítio cirúrgico. Não ocorreram fístulas na presente casuística.

PROPOSAL OF A REVISIONAL SURGERY TO TREAT SEVERE NUTRITIONAL DEFICIENCY POST-GASTRIC BYPASS.

BACKGROUND: The gastric bypass has nutritional and electrolyte disturbances rate of approximately 17%. The most common deficits are protein malnutrition, ferric and zinc, in addition to the vitamin. Although rare, some malnutrition stages reach such severity that ends up being necessary hospitalization and sometimes revisional or reversal surgical procedures. AIM:: To present a proposal of surgical revision for treatment of severe malnutrition after bariatric surgery. METHODS:: The procedure is to reconstitute the food transit through the duodenum and proximal jejunum, keeping the gastric bypass restrictive component. As an additional strategy, the gastric fundus resection is performed, aiming to intensify the suppression of the greline and avoiding excessive weight regain. RESULTS:: After initial stabilization, nutritional and electrolytic support, the procedure was performed in two patients as definitive treatment of malnutrition status. Good results were observed at one year follow up. CONCLUSION:: As improvement option and/or resolution of the nutritional alterations, surgical therapy is one of the alternatives. There is still no consensus on the surgical technique to be performed. This procedure is based on pathophysiological factors for the treatment of this condition, with good initial results, without significant clinical alterations. Longer follow-up will determine its effectiveness. RACIONAL:: O bypass gástrico consta com taxa de distúrbios nutricionais e eletrolíticos de aproximadamente 17%. Os déficits mais frequentes são a desnutrição proteica, férrica e de zinco, além das vitamínicas. Apesar de raros, alguns quadros de desnutrição atingem tal gravidade que acaba sendo indicada internação e, por vezes, procedimentos cirúrgicos revisionais ou de reversão. OBJETIVO:: Apresentar proposta de cirurgia revisional para tratamento de desnutrição severa após bypass gástrico. MÉTODOS:: O procedimento consiste em reconstituir o trânsito alimentar pelo duodeno e jejuno proximal, mantendo o componente restritivo do bypass gástrico. Como estratégia adicional, é realizada ressecção do fundo gástrico, visando intensificar a supressão da grelina e evitando reganho excessivo de peso. RESULTADO:: Após estabilização inicial com suporte hidroeletrlítico e nutricional, o procedimento foi realizado em dois pacientes como tratamento definitivo do quadro de desnutrição. Bons resultados foram observados em seguimento de um ano. CONCLUSÃO:: Como opção de melhora e/ou resolução da defasagem nutricional, a terapia cirúrgica é uma das alternativas. Ainda não há consenso quanto à técnica a ser utilizada. O procedimento aqui apresentado é baseado em fatores fisiopatológicos para o tratamento desta condição, com bons resultados iniciais, sem efeitos colaterais significativos. Seguimento de mais longo prazo é necessário para determinação de sua eficácia.

Conclusão : O procedimento de reconstituir o trânsito alimentar pelo duodeno e jejuno proximal, mantendo o componente restritivo do by-pass gástrico no tratamento da hipoglicemia hiperinsulinêmica apresentou bons resultados iniciais podendo validar sua indicação para outros casos.

EXTERNAL VALIDATION OF THE DIAREM SCORE AS REMISSION PREDICTOR OF DIABETES MELLITUS TYPE 2 IN OBESE PATIENTS UNDERGOING ROUX-EN-Y GASTRIC BYPASS.

BACKGROUND: DiaRem score consists in preoperative model for predicting remission of type 2 diabetes mellitus in obese patients who underwent gastric bypass. AIM: To evaluate the applicability of DiaRem comparing the scores obtained preoperatively with remission of T2DM after surgery. METHOD: Preoperative parameters such as age, use of insulin, oral hypoglycemic agents and glycated hemoglobin, were retrospectively evaluated in diabetic patients undergoing gastric bypass during the period between July 2012 to July 2013. Through these data the DiaRem score were applied. The results of fasting blood glucose and glycated hemoglobin were requested prospectively. RESULTS: Were selected 70 patients; the remission of T2DM after surgery was found in 42 (60%) and no remission in 28 (40%). Checking the final score, it was observed that: from 0 to 2 points, 94.1% of patients remitted completely; between 3 and 7 had remission in 68.9%, of which 42.8% complete; from 8 to 12, 57.1% achieved complete remission; between 13 to 17, 87.5% did not achieve remission and was not seen this complete remission group; between 18 to 22, 88.9% were not remitted. CONCLUSION: The DiaRem score showed appropriate tool to assess remission of T2DM in obese patients who will undergo gastric bypass.

Verificando a pontuação final, foi visto que as expectativas lançadas pelo escore DiaRem foram atingidas, pois o grupo de pacientes que alcançou a remissão foi o mesmo que obteve as menores pontuações.Conclusão: O escore DiaRem mostrou-se ferramenta apropriada para avaliar remissão de DM2 em obesos que serão submetidos ao bypass gástrico.

Food quality in the late postoperative period of bariatric surgery: an evaluation using the bariatric food pyramid.

Bariatric surgery is an effective intervention in the treatment of obesity, but lifestyle and diet should be monitored after this procedure to ensure success. The Bariatric Food Pyramid was created basing on long-term nutritional care that proposes a standard of healthy living and eating habits considering gastric capacity and specific nutritional needs. The purpose of the current study is to evaluate the life habits and diet quality of patients who have undergone bariatric surgery (who have been recovering for at least 6 months) based on the specific food pyramid. Retrospective data analysis was performed using medical records of patients who had been followed for at least 6 months after bariatric surgery. The following data were collected from patient records: age, gender, education level (years), BMI (preoperative and postoperative), percentage of excess weight loss (EWL) relative to the time of surgery, frequency of physical activity, use of nutritional supplements, usual dietary intake history, and fluid intake. Results were analyzed using descriptive statistics. We evaluated 172 patient records. In this study, there was a low prevalence of physical activity, use of vitamin-mineral supplements, and water intake. There also was low consumption of protein, fruit, vegetables, and vegetable oils. In addition, intake of carbohydrates, sugars, and fats were higher than the recommendations established by the pyramid. The results indicate that patients who have undergone bariatric surgery have an inadequate diet according to food evaluation with the specific pyramid. In the long term, this may lead to weight gain and vitamin and mineral deficiencies.

[Nutritional consultations frequency after bariatric surgery]. / Avaliação da frequência em consultas nutricionais dos pacientes após cirurgia bariátrica.

BACKGROUND: With the growth of surgical interventions to reduce obesity, there is a necessity of a periodic nutritional attendance at long term to ensure the nutritional status of the patients. AIM: To assess the adherence to the periodic nutritional attendance of patients undergoing bariatric surgery. METHODS: Data were collected from registration forms of a nutrition service from patients who underwent bariatric surgery between 2001 and 2008. RESULTS: Were evaluated 469 registration forms, of which 83% corresponded to female and 16.8% to male, with a mean age of 38.2 ± 12.03 years. The attendance showed an average of 2.04 ± 0.77 pre-operatively queries and 3.4 ± 9.19 post-operative queries and there was progressive reduction in assiduity of these patients in surgical follow-up. CONCLUSION: There was a high dropout of the patients in post-operative nutritional attendance, being primarily concerned about the high dropout after two years of surgery; this tendency may result in metabolic complications and regain of lost weight.

Gastroplastia como tratamento do diabete melito tipo 2 / Gastroplasty as a treatment for type 2 diabetes mellitus

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 por cento) eram do sexo feminino. A idade variou de 21 a 64 anos, sendo 44 anos a idade média. Setenta e sete (92,7 por cento) foram submetidos à gastroplastia (Capella) e seis (7,3 por cento) 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 por cento cessaram o uso de medicamentos para diabete e em 100 por cento dos que permaneceram medicados houve redução de mais de 65 por cento 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.

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 post-operative 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 percent) were female. Ages ranged from 21 to 64 years, with average age of 44 years. Seventy-seven (92.7 percent) underwent gastroplasty (Capella) and six (7.3 percent) 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 percent stopped using drugs for diabetes and 100 percent of those who remained medicated decreased from more than 65 percent 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.

Temporary ileostomy for the preservation of colon fistula in patients with postoperative complications: case report

Among the postoperative complications in the digestive system, the fistulae are the most common ones. The changes resulting from these fistulae are very important, once they can determine the patient's situation and the development of multiple organic failures. This paper reports the case of a patient who had relevant complications after having undergone temporary ileostomy to maintain the colon fistulized. About 90 to 95% of the digestive tract fistulae have spontaneous resolution. In some cases, the general state of the patient compromises the spontaneous closure. In this study, after one month of nutritional support and medicine treatment, the spontaneous closure of the colon fistula did not occur, thus, a surgical intervention was necessary to solve the case. (AU)

Dentre as complicações pós-operatórias do aparelho digestório, as fístulas apresentam alta incidência. As alterações decorrentes dessas fístulas são muito importantes, pois podem determinar o agravamento do estado geral do paciente e o desenvolvimento de insuficiências orgânicas múltiplas. O presente trabalho relata o caso de um paciente com complicações relevantes após a realização de uma ileostomia temporária para preservação do cólon fistulizado. A maioria (90-95%) das fístulas do trato digestório tem resolução espontânea; entretanto, em alguns casos, o estado geral do paciente compromete o fechamento espontâneo. No caso em estudo, após um mês de suporte nutricional e tratamento medicamentoso, o fechamento espontâneo da fístula de cólon não ocorreu, sendo necessária a intervenção cirúrgica para resolução do caso.

Tratamento da obesidade mórbida com gastrectomia vertical / Treatment of morbid obesity with vertical gastrectomy

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 pósoperatória 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 por cento) 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/m² (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 por cento). Como evolução pós-operatória, 24 pacientes (21 por cento) necessitaram de cuidados em unidade de terapia intensiva e houve um total de quatro óbitos (3,5 por cento). 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.

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 percent) of the patients were male and the average age was 38 years old. The body mass index was 45,9 kg/m². About the time of hospitalization, there was a minimum of 3 and maximum of 48 days. The main comorbidity was systemic arterial hypertension (63 percent). About the evolution after the surgery, 24 patients (21 percent) needed intensive care and four patients died (3,5 percent). 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.
