- The Edmonton Obesity Staging System: assessing a potential tool to improve the management of obesity surgery in the Brazilian public health services(2020) OGASSAVARA, Nicolas Chiu; DIAS, Joao Gabriel Magalhaes; PAJECKI, Denis; SIQUEIRA, Jose de Oliveira; SANTO, Marco Aurelio; TESS, Beatriz HelenaBackground: Limited access to publicly funded, insurance-covered, and self-paid obesity surgery is a reality worldwide. Waiting lists for procedures are usually based on chronologic criteria and body mass index (BMI)-defined obesity categorization. Obesity classification systems assess overall health and have been proposed as an alternative. Objective: To investigate the correlation between BMI-based classification and the Edmonton Obesity Staging System (EOSS) to support current evidence that the assessment of the clinical severity of obesity could be a helpful tool to maximize access to surgery. Setting: University hospital, Brazil. Methods: Retrospective analysis of all 2011 to 2014 adult patients who underwent obesity surgery under the public health system. Data on sex, age, presurgical BMI, and co-morbidities were extracted from hospital records. Spearman correlation coefficients were used to assess the strength and direction of the relationship between BMI classification and EOSS. Results: Of 565 patients, 79% were female, mean age 44.1 +/- 10.9 years and mean BMI 46.9 +/- 6.2 kg/m(2). The most common EOSS stage was 2 (86.5%), followed by stages 3 (8.5%) and 1 (4.9%). There was no correlation between the severity of obesity measured by BMI and EOSS (p = - .030, P = .475). Older patients had higher Edmonton scores (p = .308, P < .001). No difference was observed regarding sex. Conclusions: No correlation was found between EOSS and BMI and between these and sex. Age correlated with both obesity indicators. EOSS was reproducible in Brazilian surgical patients and may be an important tool from a health services perspective contributing to the more efficient use of limited resources for obesity surgery.

A.; CECCONELLO, I.- Tratamento de curto prazo com liraglutide no reganho de peso após cirurgia bariátrica(2013) PAJECKI, Denis; HALPERN, Alfredo; CERCATO, Cintia; MANCINI, Marcio; CLEVA, Roberto de; SANTO, Marco AurélioOBJECTIVE: To evaluate the results of the use of liraglutide in a group of patients undergoing surgical treatment of morbid obesity with unsatisfactory weight loss or regain of more than 15% of minimum reached weight. METHODS: The authors conducted a retrospective analysis of 15 operated patients who had excess weight loss <50% after two years of follow-up or regained weight more than 15% of the minimum reached weight. We included only patients who had the expected ""surgical anatomy"", assessed by contrast radiography and endoscopy. Mean age was 47.2 ± 12.5 years, and patients received liraglutide at doses from 1.2 to 3.0 mg/day for eight to 28 weeks follow-up. RESULTS: Surgical treatment induced a weight loss of 34.1 ± 16.5 kg. The average weight regain after 5.3 ± 3.3 years was 14.2 ± 12.1 Kg. The average weight was significantly reduced after treatment with liraglutide (100.9 ± 18.3 kg. vs Kg 93.5 ± 17.4, p <0.0001). Six patients had nausea and two discontinued therapy due to the cost of medication. CONCLUSION: medical treatment directed to the control of satiety using liraglutide may be an alternative treatment of patients with poor weight loss or weight regain after surgery when no technical problem has been identified.
conferenceObject Assessment of Body Composition in Morbid Obesity: a Comparative Study Between Body Impedance and Adiposity index Methods(2012) SANTO, M. A.; RICCIOPPO, D.; PAJECKI, D.; KAWAMOTO, F.; MATSUDA, M.; CECCONELLO, IIntroduction Obesity has become an epidemic public health problem. A reliable method to assess body composition and monitor the effectiveness of treatments for the morbid obesity is mandatory. However, there is still controversy as to which method to use for this purpose. Two Methods are validated in the literature, bioelectrical impedance analysis (BIA) and body adiposity index (BAI). The present study compared these methodologies. Materials & Methods We evaluated 167 patients undergoing bariatric surgery, women prevailed (82.59 %), averaging 44 years-old and mean BMI of 49.48 kg/m2. Weight, height and hip circumference were measured. Body fat (BF) was calculated by BIA and BAI. The following formulas were used: BIA: BF in kg=023.25+(0.09x resistance in ohms)+(1.00x weight in kg)-(0.08xheight in cm)+(0.13x age in years). BAI: BF% of the total weight 0 (hip circumference in centimeters/height in meters x height in meters)-18. Results The patients had an average of 53.35 % (± 5.37) of BF according to BIA, and BAI showed 50.51 % (± 13.59) of BF. There is no difference between the two Methods (p<0,05), even when stratified by BMI (BMI<45, 4550). Essa diferença variou quando o IMC foi dividido em três faixas, abaixo de 45 kg/m2 a diferença foi de 3,1 %, entre 45,1 a 49,99 kg/m2 a diferença foi de 3,78 %, acima de 50 kg/m2 a diferença foi de 1,86%. Discussion The BAI is a simple method of implementation, low cost and effective, when compared to other Methods validated for morbidly obese patients. Conclusion BAI is an effective method to assess BF, comparable to BIA, and also proved to be effective in super obese patients.- Reply to comment on Sleeve Gastrectomy Versus Roux-en-Y Gastric Bypass in the Elderly: 1-Year Preliminary Outcomes in a Randomized Trial (BASE Trial)(2022) PAJECKI, Denis; DANTAS, Anna Carolina Batista
conferenceObject Preoperative Weight Loss in Super Obesity: Influence on Perioperative Morbidity and Mortality in Patients undergoing Gastric Bypass(2012) SANTO, M. A.; RICCIOPPO, D.; PAJECKI, D.; KAWAMOTO, F.; MATSUDA, M.; CECCONELLO, IIntroduction Super obesity (SO) is increasing in greater proportions, and now represents 30 % of morbidly obese patients. In SO morbidity and mortality rates are greater. The preoperative weight loss in SO decreases operative time, and apparently diminishes morbidity. Based on these data, we initiated a program of preoperative weight loss for the SO. The treatment is based on hospitalization, low-calorie diet, biometrics control and physical activities, aiming to analyze weight loss and influence of weight loss in the perioperative outcome. Materials & Methods Thirty patients underwent our SO preop weight loss program, from 2006 to 2011. The mean age was 46 years, and mean BMI of 66 kg/m2 and the majority was female. All patients underwent gastric bypass after the weight loss. The average caloric intake was 5 cal/Kg/day. Results The mean weight loss was 1.9 kg/week, and after 14 weeks the mean weight loss was15.2 % of initial weight. The mean hospital stay was 21.3 weeks, and the mean weight loss was 19.7 %. All had satisfactory recovery from surgery. The mortality was null. In the last five years, from the total of 592 surgeries, 193 was performed in SO. The SO and general morbidity was 11.14 % and 20.2 %, respectively, and mortality 0.84 % and 2.07 %. Discussion In SO a preoperative weight loss is an important tool to reduce surgical risks. Hospitalization, with low-calorie diet and multidisciplinary follow-up is a safe and effective way to achieve weight loss preoperatively. Conclusion After a mean of 19,7 % of initial body weight loss, the studied group showed an important decreasing in morbimortality when compared with our previous experience. Preoperative weight loss should be encouraged in SO, and a specific program can significantly diminish surgical risks in this complex group of obeses.
