Resultados cardiometabólicos de largo plazo tras cirugía bariátrica: control de comorbilidades, pérdida y reganancia de peso a los 5 años de seguimiento / Long-term cardiometabolic results after bariatric surgery: Control of comorbidities, weight loss and regain at 5 years of follow-up

Introducción. La cirugía bariátrica y metabólica (CBM) es efectiva en lograr pérdida de peso a corto plazo. Sin embargo, existe evidencia limitada en desenlaces clínicos y metabólicos a largo plazo. Métodos. Estudio longitudinal retrospectivo con pacientes llevados a baipás gástrico en Y de Roux (BGYR) o gastrectomía en manga (MG) por laparoscopia en Bogotá, D.C., Colombia, entre 2013 y 2021. El cambio de peso, control de comorbilidades y resultados metabólicos se recopilaron al inicio del estudio, 3, 6 y 12 meses después de cirugía, y anualmente hasta el quinto año. Las tasas de control de comorbilidades se evaluaron mediante la prueba Kaplan-Meier. Se utilizó un modelo de riesgos proporcionales de Cox para evaluar el efecto de covariables en la reganancia de peso. Resultados. De 1092 pacientes con CBM (71,4 % MG y 28,6 % BGYR), 67 % eran mujeres, con mediana de edad 48 años e índice de masa corporal de 35,5 Kg/m2. Después de cinco años de seguimiento, la tasa de control en diabetes mellitus fue 65,5 %, en hipertensión 56,6 % y en dislipidemia 43,6 %. La tasa de reganancia de peso fue 28 %, sin diferencias entre MG vs BGYR (p=0,482). El tiempo promedio hasta peso nadir fue 14 meses. La edad al momento de CBM fue el mejor predictor independiente de reganancia (HR=1,02, IC95% 1,01-1,04), pero con efecto clínico modesto. Conclusión. La CBM es segura y muestra beneficios a largo plazo en la pérdida de peso y control de comorbilidades en población colombiana.

Introduction. Bariatric and metabolic surgery (BMS) has shown its efficacy in achieving short-term weight loss. However, there is limited evidence regarding long-term clinical and metabolic outcomes. Methods. Retrospective longitudinal study with patients who underwent laparoscopic Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) interventions in Bogotá, Colombia, between 2013 and 2021. Weight change, comorbidity control, and metabolic outcomes were collected at the onset, 3-, 6-, and 12-month post-surgery, and annually up to the fifth year. Comorbidity control rates were assessed using the Kaplan-Meier test. A Cox proportional hazards model was used to evaluate the effect of covariates on weight regain. Results. Of 1092 patients with BMS (71.4% SG and 28.6% RYGB), 67% were women, with a median age of 48 years, BMI 35.5 kg/m2. After five years of follow-up, the control rate in diabetes mellitus was 65.5%, in hypertension 56.6%, and dyslipidemia 43.6%. The weight regain rate was 28% with no differences between SG vs RYGB (p=0.482). The mean time to nadir weight was 14 months. Age at the time of BMS was the best independent predictor of weight regain (HR=1.02, 95%CI: 1.01-1.04), but with a modest clinical effect. Conclusion. BMS is safe and shows long-term benefits in weight loss and control of comorbidities in Colombian population.

Gastroplastia como medida terapêutica em pacientes obesos hipertensos / Gastroplastia as a therapeutic measure in obese hypertensive patients

A hipertensão arterial (HA) e a obesidade são doenças crônicas que se interrelacionam por meio de um quadro complexo de comunicação hormonal e uma série de cascatas enzimáticas. Isso faz com que o manejo dessas comorbidades seja complexo e multifatorial, muitas vezes levando a abandono ou falha terapêutica por parte de pacientes e profissionais de saúde, levando, então, às complicações dessas patologias. Há diversas formas de manejo e a gastroplastia, também conhecida como cirurgia bariátrica, é uma técnica cirúrgica que vem apresentando como alternativa satisfatória para o manejo terapêutico (AU).

Arterial hypertension (AH) and obesity are chronic diseases that are interrelated through a complex framework of hormonal communication and a series of enzymatic cascades. This makes the management of these comorbidities complex and multifactorial, often leading to treatment abandonment or failure by patients and health professionals, thus leading to complications of these pathologies. There are several forms of management and gastroplasty, also known as bariatric surgery, is a surgery that has been presented as a satisfactory alternative for therapeutic management (AU),

Factores de riesgo asociados a la pérdida insuficiente o ganancia significativa de peso en pacientes sometidos a cirugía bariátrica / Risk factors associated with insufficient weight loss or significant weight gain in patients undergone bariatric surgery

Introducción. La cirugía bariátrica es efectiva para inducir una rápida pérdida del exceso de peso, pero existen dudas sobre la duración de este efecto a largo plazo. Este estudio buscaba identificar la proporción de pacientes operados que presentaron una pérdida insuficiente o una ganancia significativa de peso y los posibles factores relacionados. Métodos. Estudio de cohorte retrospectivo en pacientes adultos sometidos a cirugía bariátrica. Se describieron variables demográficas y clínicas. Se realizó un análisis multivariado para identificar factores relacionados con un peso fuera de metas posterior a la cirugía. Resultados. Se incluyeron 187 pacientes, 117 con baipás gástrico y 70 con manga gástrica. La mediana de índice de masa corporal preoperatorio fue 41,3 kg/m2 y postoperatorio de 28,8 kg/m2. El 94,7 % de los pacientes en ambos grupos logró una adecuada pérdida del exceso de peso. La ganancia de peso mayor del 20 % se presentó en el 43,5 % de los pacientes, siendo mayor en el grupo de manga gástrica (p<0,004). Los factores independientes para ganancia de peso fueron el sexo masculino (OR 5,5), cirugía tipo manga gástrica (OR 3,4), síndrome de apnea del sueño (OR 2,9) y enfermedad mental medicada (OR 2,8). Conclusión. La cirugía bariátrica produce una pérdida del exceso de peso suficiente en casi la totalidad de los pacientes, pero un buen número recuperan peso luego de 3 años. Los principales factores asociados a ganancia de peso son el sexo masculino y la cirugía tipo manga gástrica

Introduction. Bariatric surgery is highly effective in inducing rapid excess body weight loss but there are doubts about its effect on long-term. This study seeks to identify the number of patients that underwent bariatric surgery who present insufficient weight loss or significant weight gain and the possible related factors. Methods. Retrospective cohort study of adult patients who underwent bariatric surgery. Demographic and clinical variables are described. A multivariate analysis was performed to identify factors related to patient weight outside the set goals postoperatively. Results. 187 patients were included (117 gastric bypass, 70 gastric sleeve). The median preoperative body mass index was 41m/kg2 and 28.8m/kg2 postoperatively. 94.7% of the patients in both groups achieved adequate excess body weight loss. Weight gain (>20%) occurred in 43.5% of the patients, with the probability being higher in the gastric sleeve group (p<0.004). Independent factors for weight gain were male gender (OR 5.5), gastric sleeve surgery (OR 3.4), sleep apnea syndrome (OR 2.9), and mental illness under treatment (OR 2.8). Conclusions. Bariatric surgery produces sufficient loss of excess weight in almost all patients, but a good number of them regain weight after 3 years. The main factors associated with weight gain are male gender and gastric sleeve surgery

Baipás gástrico versus manga gástrica para el controlde diabetes tipo 2 en pacientes obesos / Gastric bypass versus gastric sleeve for the management of type 2 diabetes in obese patients

Introducción. La diabetes mellitus tipo 2 y la obesidad son enfermedades con alta prevalencia, gran morbi-mortalidad y elevados costos en salud. La cirugía bariátrica ha demostrado efectividad para inducir pérdida de peso y un control adecuado de la glicemia. Métodos. Estudio observacional analítico retrospectivo, realizado entre 2014 y 2019 en una institución de alta complejidad. Se incluyeron pacientes prediabéticos y diabéticos sometidos a cirugía bariátrica tipo baipás gástrico en Y-de-Roux o manga gástrica. Se analizaron la mejoría o resolución de la diabetes y la pérdida del exceso de peso a los 6, 12, 24 y 36 meses luego de la cirugía. Resultados. Se incluyeron 103 pacientes en el estudio, 45 pacientes diabéticos y 58 pacientes prediabéticos. La única variable perioperatoria con diferencia estadísticamente significativa fue el tiempo quirúrgico mayor en el baipás (70 vs. 47,5 minutos; p<0,001). La pérdida de exceso de peso fue mayor en el baipás. Los pacientes diabéticos sometidos a baipás tuvieron un mayor porcentaje de resolución o control comparados con los sometidos a manga gástrica. En los pacientes prediabéticos hubo resolución en ambos grupos luego de 24 meses de seguimiento. Conclusión. El baipás gástrico y la manga gástrica presentan excelentes resultados en cuanto a pérdida de peso y control metabólico en pacientes con diabetes mellitus tipo 2 y prediabetes, pero en nuestros pacientes se lograron resultados superiores en ambos aspectos con el baipás gástrico

Introduction. Type 2 diabetes mellitus and obesity are diseases with high prevalence, high morbidity and mortality and high health costs. Bariatric surgery has proven effective in inducing weight loss and adequate glycemic control. Methods. Retrospective analytical observational study conducted between 2014 and 2019 in a high-complex institution. Prediabetic and diabetic patients undergoing Roux-en-Y gastric bypass or gastric sleeve were included; analyzing the improvement or resolution of diabetes and the loss of excess weight at 6, 12, 24 and 36 months after surgery. Results. One-hundred and three patients were included in the study, 45 diabetic patients and 58 pre-diabetic patients. The only perioperative variable with a statistically significant difference was the longer surgical time in the bypass (70 vs. 47.5 min; p<0.001). Loss of excess weight was always greater in bypass. Diabetic patients who underwent bypass had a higher percentage of resolution or control compared to those who underwent the sleeve procedure. In pre-diabetic patients, there was 100% resolution in both groups after 24 months of follow-up. Conclusion. Gastric bypass and gastric sleeve present excellent results in terms of weight loss and metabolic control in patients with type 2 diabetes mellitus and pre-diabetes, but superior results in both aspects were achieved with the first technique in our patients

Review and pictorial essay on complications of bariatric surgery

SUMMARY Obesity is a chronic disease characterized by excess fat in the body and a real public health problem. Bariatric surgery, in recent decades, has gained space in its treatment due to the efficiency obtained in weight loss and significant reduction of the related comorbidities. The most commonly performed bariatric procedures include Roux-en-Y gastric bypass, adjustable gastric band, and laparoscopic sleeve gastrectomy. Possible complications described include fistulas, dehiscence, marginal ulcers, intestinal obstruction, internal hernias, and anastomotic stenosis. These complications may have unfavorable clinical outcomes since symptoms are often nonspecific. Abdominal computed tomography (CT) is an important tool in the evaluation of postoperative complications, both in the immediate and late postoperative status of patients undergoing such a procedure. We analyzed the most illustrative tomographic findings of the different complications after reducing gastroplasty in 203 patients without distinction of age or gender. Correct interpretation requires radiologists to understand the surgical technique since postoperative anatomy and surgery-specific complications may be obstacles to proper interpretation.

RESUMO A obesidade é uma doença crônica caracterizada pelo excesso de tecido adiposo no organismo e um verdadeiro problema de saúde pública. A cirurgia bariátrica, nas últimas décadas, ganhou espaço no seu tratamento devido à eficiência obtida na perda ponderal e redução importante de comorbidades relacionadas. Os procedimentos bariátricos mais comumente realizados incluem o bypass gástrico em Y-de-Roux, a banda gástrica ajustável e a gastrectomia vertical — Sleeve — por via laparoscópica. Entre as complicações possíveis descritas podem ser citadas: fístulas, deiscências, úlceras marginais, obstrução intestinal, hérnias internas e estenose de anastomoses. Essas complicações podem apresentar desfechos clínicos desfavoráveis, uma vez que os sintomas são frequentemente inespecíficos. A tomografia computadorizada de abdome (TC) constitui uma importante ferramenta na avaliação de complicações pós-operatórias, tanto no status pós-cirúrgico imediato quanto tardias, de pacientes submetidos a tal procedimento. Foram analisados os achados tomográficos mais ilustrativos das diferentes complicações pós-gastroplastia redutora ocorridas em 203 pacientes sem distinção de idade ou gênero. A correta interpretação requer que os radiologistas compreendam a técnica cirúrgica, uma vez que a anatomia pós-cirúrgica e as complicações específicas da cirurgia podem ser obstáculos para a adequada interpretação.

Opportunities and challenges of endoscopic sleeve gastroplasty / 南方医科大学学报

Obesity and its complications, such as type 2 diabetes, hypertension, hyperlipidemia, nonalcoholic fatty liver, are serious global public health problems. Endoscopic sleeve gastroplasty (ESG) can reduce the length and width of the stomach by simulating the anatomical structure of surgical sleeve gastrectomy to reduce the capacity of the stomach, and is safe and effective to reduce weight. ESG has the advantages of non- invasiveness, no gastrectomy, repeatability, simple operation, no incision scar, few complications, short hospital stay and quick postoperative recovery. As an intermediate means of medical treatment and surgery, ESG provides a new method for weight loss for obese patients who cannot tolerate or are unwilling to undergo surgery. Herein we trace the origin of ESG, analyze the unique advantages of ESG suture, explore the technical improvement in the development of ESG, and briefly describe the weight reduction effect of ESG and compare the curative effect of ESG with laparoscopic sleeve gastrectomy. ESG has undergone rapid development and maturity but also faces such challenges as the lack of established standard procedures, unclear weight reduction mechanism, and clarification of the indications for operation. Still, ESG is expected to become the mainstream technique for weight reduction.

Comparative analysis between patients undergoing Gastric Bypass and Sleeve Gastroplasty in a private hospital in Sao Luis-MA

Abstract Purpose: To compare the satisfaction levels about the surgery and anesthesia management, and to analyze the postoperative outcomes of patients undergoing Gastric Bypass and Sleeve Gastroplasty surgeries in a private hospital in Sao Luís-MA. Methods: The sample consisted of patients undergoing Bypass and Sleeve bariatric surgeries from August 2018 to August 2019, who were in the range of 18 and 70 years old and had not used drugs or presented cardiac arrhythmias, dilated cardiomyopathy, and conduction disorder heart. Data were collected from the evaluation forms and recorded in a form with closed questions. Results: Most patients were female (Bypass - 56% and Sleeve - 67.4%) and aged between 30 and 39 years old (Bypass - 32% and Sleeve - 55.8%). Information (Bypass - 92% and Sleeve - 86.1%) was the highest satisfaction index found. Sleepiness in the immediate postoperative period (Bypass - 92% and Sleeve - 93%) was the main side effect. There were no postoperative complications in patients between the two types of surgery. Conclusions: Patients submitted to Bypass and Sleeve were completely satisfied with the perioperative management. There was no statistically significant difference when comparing adverse effects between the techniques.

Randomized, double-blind, placebo-controlled study of the analgesic effect of intraoperative esmolol for laparoscopic gastroplasty

Abstract Purpose To evaluate the analgesic effect of esmolol in patients submitted to laparoscopic gastroplasty. Methods Forty patients aged between 18 and 50 years with American Society of Anesthesiologists (ASA) physical status scores of II and III who underwent gastric bypass were allocated to two groups. Group 1 patients received a 0.5-mg/kg bolus of esmolol in 30 mL of saline before induction of anesthesia, followed by an infusion at 15 µg/kg/min until the end of surgery. Group 2 patients received 30 mL of saline as a bolus and then an infusion of saline. Anesthesia included fentanyl (3 µg/kg), propofol (2-4 mg/kg), rocuronium (0.6 mg/kg), and 2% sevoflurane, with remifentanil if necessary. The following parameters were evaluated: pain intensity over 24h, remifentanil consumption, the first analgesic request, morphine consumption, and side effects. Results Pain intensity was lower in the esmolol group except at T0 (after extubation) and 12h postoperatively. Remifentanil supplementation, recovery time, and postoperative morphine supplementation were lower in the esmolol group. No differences in the time to the first analgesic request or side effects were found between the groups. Conclusion Intraoperative esmolol promotes reductions in pain intensity and the need for analgesic supplementation without adverse effects, thus representing an effective drug for multimodal analgesia in gastroplasty.

Lipoabdominoplastia em âncora / Anchor lipoabdominoplasty

A obesidade mórbida se caracteriza por acúmulo de tecido adiposo que se distribui de maneira heterogênea em todo o organismo, tendo a gastroplastia como o mais recente método de tratamento cirúrgico. Após perda considerável de peso, o doente apresenta sobras cutâneas, sob essas sobras acumulam-se secreções que favorecem a instalação de infecções cutâneas que podem ser minimizadas com a execução de dermolipectomias. Os autores descrevem a técnica de lipoabdominoplastia em âncora, adaptando os princípios de descolamento reduzido do retalho, lipoaspiração de abdome e flancos, e preservação da fáscia de Scarpa infraumbilical associado à marcação pré-cirúrgica em "Fleur-de-Lis". A técnica foi realizada em 17 pacientes em pós-operatório tardio de gastroplastia, entre janeiro de 2018 e junho de 2019, com idade entre 35 a 66 anos, sendo 16 pacientes do sexo feminino e 1 do sexo masculino. Todos os pacientes foram operados com exames pré-operatórios dentro da normalidade, condições clínicas satisfatórias e IMC<30. Na presente série de casos, um paciente apresentou epidermólise de coto umbilical; todos os pacientes apresentaram edema e equimoses, e um paciente apresentou seroma no 13º dia de pós-operatório. Hematoma, necrose, infecção, deiscência de ferida operatória ou eventos tromboembólicos não foram observados em nenhum paciente. A técnica demostrou ser segura e eficaz no tratamento de pacientes com excedente cutâneo abdominal, com melhora do contorno corporal, porém há necessidade de maior tempo de acompanhamento pós-operatório e maior número de casos operados para melhor mensurar os resultados, bem como a incidência de complicações.

Morbid obesity is characterized by the accumulation of adipose tissues distributed heterogeneously throughout the body, and gastroplasty is the latest method of surgical treatment. After considerable weight loss, patients present with excess skin under which secretions accumulate, increasing susceptibility for skin infections, which can be minimized with dermolipectomy. Herein, we describe the anchor lipoabdominoplasty technique, adapting the principles of reduced flap detachment, abdominal and flank liposuctions, and preservation of the infraumbilical Scarpa's fascia associated with the preoperative fleurde- lis marking. The technique was used for seventeen patients, including sixteen women and one man, with late postoperative gastroplasty, aged 35­66 years in the period from January 2018 to June 2019. The patients presented with normal preoperative testing, satisfactory clinical conditions, and body mass index scores less than 30 kg/m2. In the present case series, one patient had umbilical cord remnant epidermolysis; all patients had edema and ecchymosis; and one patient had seroma on postoperative day 13. Hematoma, necrosis, infection, wound dehiscence, or thromboembolic events were not observed in any patient. The technique is safe and effective in the treatment of patients with abdominal excess skin, improving their body contour. However, longer postoperative follow-up periods and more cases are necessary to better measure the results and incidence of complications.

Critical analysis of surgical treatment techniques of morbid obesity / Análise crítica das técnicas de tratamento cirúrgico da obesidade mórbida

ABSTRACT Introduction: Obesity is a disease of high prevalence in Brazil and in the world, and bariatric surgery, with its different techniques, is an alternative treatment. Objective: To compare techniques: adjustable gastric band (AGB), sleeve gastrectomy), Roux-en-Y gastric bypass (RYGB) and biliopancreatic diversion (BPD) analyzing leaks, bleeding, death, weight loss, resolution of type 2 diabetes, systemic arterial hypertension, dyslipidemia and obstructive sleep apnea. Methods: Were selected studies in the PubMed database from 2003 to 2014 using the descriptors: obesity surgery; bariatric surgery; biliopancreatic diversion; sleeve gastrectomy; Roux-en-Y gastric bypass and adjustable gastric banding. Two hundred and forty-four articles were found with the search strategy of which there were selected 116 studies through the inclusion criteria. Results: Excess weight loss (EWL) after five years in AGB was 48.35%; 52.7% in SG; 71.04% in RYGB and 77.90% in BPD. The postoperative mortality was 0.05% in the AGB; 0.16% on SG; 0.60% in RYGB and 2.52% in BPD. The occurrence of leak was 0.68% for GBA; 1.93% for SG; 2.18% for RYGB and 5.23% for BPD. The incidence of bleeding was 0.44% in AGB; 1.29% in SG; 0.81% in RYGB and 2.09% in BPD. The rate of DM2 resolved was 46.80% in AGB, 79.38% in SG, 79.86% in RYGB and 90.78% in BPD. The rate of dyslipidemia, apnea and hypertension resolved showed no statistical differences between the techniques. Conclusion: The AGB has the lowest morbidity and mortality and it is the worst in EWL and resolution of type 2 diabetes. The SG has low morbidity and mortality, good resolution of comorbidities and EWL lower than in RYGB and BPD. The RYGB has higher morbidity and mortality than AGB, good resolution of comorbidities and EWL similar to BPD. The BPD is the worst in mortality and bleeding and better in EWL and resolution of comorbidities.

RESUMO Introdução: A obesidade é afecção de alta prevalência no Brasil e no mundo e a cirurgia bariátrica, com suas diferentes técnicas, é alternativa para o tratamento. Objetivo: Comparar as técnicas da banda gástrica ajustável (BGA), gastrectomia vertical (GV), gastroplastia com derivação em Y-de-Roux (GDYR) e derivação biliopancreática (DBP) focando fístula, sangramento, óbito, perda e reganho ponderal, e resolução das comorbidades diabete melito tipo 2 (DM2), hipertensão arterial sistêmica (HAS), dislipidemia e apneia obstrutiva do sono (AOS). Métodos: Buscou-se os estudos na base de dados PubMed de 2003 a 2014 usando os descritores: obesity surgery; bariatric surgery; biliopancreatic diversion; sleeve gastrectomy; Roux-en-Y gastric bypass e adjustable gastric banding. Dessa busca foram recuperadas 244 publicações sendo selecionados 116 após aplicar os critérios de inclusão/exclusão. Resultados: A perda de excesso de peso (PEP) após cinco anos foi 48,35% na BGA; 52,7% na GV; 71,04% na GDYR e 77,90% na DBP. A mortalidade pós-operatória foi 0,05% na BGA; 0,16% na GV; 0,60% na GDYR e 2,52% na DBP. A ocorrência de fístulas foi 0,68% para BGA; 1,93% para GV; 2,18% para GDYR e 5,23% para DBP. A ocorrência de sangramento foi 0,44% na BGA; 1,29% na GV; 0,81% na GDYR e 2,09% na DBP. A taxa do DM2 resolvida foi de 46,80% na BGA, 79,38% na GV, 79,86% na GDYR e 90,78% na DBP. A taxa de dislipidemia, apneia e hipertensão resolvidas não demonstraram diferenças estatísticas entre as técnicas. Conclusões: A BGA apresenta a menor morbimortalidade e é a pior em PEP e resolução do DM2. A GV apresenta baixa morbimortalidade, boa resolução das comorbidades e PEP inferior às GDYR e DBP. A GDYR apresenta morbimortalidade superior à BGA, boa resolução das comorbidades e PEP semelhante à DBP. A DBP é a pior em mortalidade e sangramento e melhor em PEP e resolução das comorbidades.

Current Status of Bariatric Endoscopy in Obesity Control / 대한내과학회지

Obesity and metabolic syndrome affect ~40% of individuals in the United States alone. They are significant conditions that can cause severe economic problems. Obesity is also a global issue, with ~400 million obese adults worldwide. Moreover, the number of overweight children is increasing. Bariatric surgery is the gold standard treatment for obesity; however, endoscopic approaches may have a significant role in improving metabolic syndrome and achieving weight loss. Many endoscopic methods have been introduced, some of which are currently available and some that are undergoing experimentation. Endoscopists have a role in the treatment of obesity because endoscopic therapies are expected to become safer and more efficacious in the coming years. Endoscopic bariatric therapies can be categorized as space occupying, malabsorption, and gastric volume reduction. In this review, we summarize the currently available endoscopic procedures.

Introdução: Os pacientes submetidos à gastroplastia apresentam importante perda de peso e a cirurgia plástica representa um importante meio de tratamento do excesso de pele. Método: Estudo prospectivo foi realizado em pacientes submetidos à abdominoplastia pós-gastroplastia no período de janeiro de 2011 a dezembro de 2016 em hospital público. As variáveis analisadas foram: IMC (Índice de Massa Corporal) antes da gastroplastia e antes da cirurgia plástica, perda de peso, peso do retalho retirado, comorbidades e complicações. Resultados: 107 pacientes que realizaram abdominoplastia foram incluídos. Média de idade foi 41 anos. O IMC médio antes da cirurgia plástica foi 27,6 ± 3,7 Kg/m2. Perda de peso médio foi 47,7 ± 17,3 Kg. O IMC máximo antes da gastroplastia foi 45,5 ± 7,5 Kg/m2 e o IMC foi 18,6 ± 9,3 Kg/m2. Comorbidades presentes antes da plástica foram: hipertensão arterial (11,1%), artropatia (4,6%), diabete melito (5,6%) e síndrome metabólica (5,6%). Catorze (13,1%) pacientes realizaram herniorrafia durante a abdominoplastia. A taxa de complicações foi 31,5%. O peso antes da gastroplastia, IMC antes da gastroplastia, perda de peso médio, comorbidades, peso do retalho do abdome e IMC > 20Kg/m2 foram fatores associados significativamente a complicações pós-operatórias. Conclusões: A gastroplastia em Y de Roux foi uma terapêutica efetiva na resolução de comorbidades em obesos. Comorbidades, peso antes da gastroplastia, perda de peso médio, quantidade de tecido retirado do abdome e IMC > 20Kg/m2 levaram significativamente a mais complicações em pacientes pósbariátricos submetidos à abdominoplastia. A cirurgia plástica é importante no cuidado integral ao paciente obeso e otimizou os resultados alcançados com a cirurgia bariátrica.

Introduction: Patients who undergo vertical-banded gastroplasty- Roux-en-Y gastric bypass (VBG-RYGB) have significant weight loss, and abdominoplasty (AP) is an effective corrective surgery for removing excess skin. Methods: A prospective study conducted from January 2011 to December 2016 in a public hospital evaluated patients who underwent AP after VBG-RYGB. The analyzed variables were body mass index (BMI) before VBG-RYGB, BMI before AP, weight loss, weight of the excised abdominal flap, comorbidities, and complications. Results: For this study, 107 patients who underwent AP were included. The patients' mean age was 41 years; BMI before AP, 27.6 ± 3.7 kg/m2; and mean weight loss, 47.7 ± 17.3 kg. The maximum BMI before bariatric surgery was 45.5 ± 7.5 kg/m2, and the difference between the maximum BMI before VBG-RYGB and before corrective surgery was 18.6 ± 9.3 kg/m2. The comorbidities observed before VBG-RYGB were arterial hypertension (11.1%), arthropathy (4.6%), diabetes mellitus (5.6%), and metabolic syndrome (5.6%). Fourteen patients (13.1%) underwent herniorrhaphy during AP. The overall complication rate was 31.5%. Weight before VBGRYGB, BMI before VBG-RYGB, mean weight loss, comorbidities, abdominal flap weight, and BMI of >20 kg/m2 were significantly associated with postoperative complications. Conclusions: VBGRYGB was an effective approach to reduce comorbidities in obese patients. Comorbidities, weight before VBG-RYGB, mean weight loss, amount of tissue removed from the abdomen, and BMI of >20 kg/m2 significantly increased the complication rate in the gastric bypass patients who underwent AP. Furthermore, AP is fundamental for the comprehensive care of obese patients and has optimized the results achieved with VBG-RYGB.

Airway positive pressure vs. exercises with inspiratory loading focused on pulmonary and respiratory muscular functions in the postoperative period of bariatric surgery / Pressão positiva nas vias aéreas versus exercícios com carga inspiratória na função pulmonar e na função muscular respiratória no pós-operatório de cirurgia bariátrica

ABSTRACT Background: Bariatric surgery can trigger postoperative pulmonary complications due to factors inherent to the procedure, mainly due to diaphragmatic dysfunction. Aim: To evaluate and compare the effects of two levels of positive pressure and exercises with inspiratory load on lung function, inspiratory muscle strength and respiratory muscle resistance, and the prevalence of atelectasis after gastroplasty. Methods: Clinical, randomized and blind trial, with subjects submitted to bariatric surgery, allocated to two groups: positive pressure group, who received positive pressure at two levels during one hour and conventional respiratory physiotherapy and inspiratory load group, who performed exercises with load linear inspiratory pressure, six sets of 15 repetitions, in addition to conventional respiratory physiotherapy, both of which were applied twice in the immediate postoperative period and three times a day on the first postoperative day. Spirometry was performed for pulmonary function analysis, nasal inspiratory pressure for inspiratory muscle strength and incremental test of respiratory muscle resistance for sustained maximal inspiratory pressure, both preoperatively and on hospital discharge on the second postoperative day. Results: There was no significant difference (p> 0.05) in the expiratory reserve volume and in the tidal volume in the pre and postoperative periods when compared intra and intergroup. There was no significant difference (p>0.05) in the nasal inspiratory pressure and the maximal inspiratory pressure maintained in the inspiratory load group in the intragroup evaluation, but with a significant difference (p<0.05) compared to the positive pressure group. The prevalence of atelectasis was 5% in both groups with no significant difference (p>0.05) between them. Conclusion: Both groups, associated with conventional respiratory physiotherapy, preserved expiratory reserve volume and tidal volume and had a low atelectasis rate. The inspiratory loading group still maintained inspiratory muscle strength and resistance of respiratory muscles.

RESUMO Racional : A cirurgia bariátrica pode desencadear complicações pulmonares no pós-operatório devido a fatores inerentes ao procedimento, sobretudo pela disfunção diafragmática. Objetivo : Avaliar e comparar os efeitos da aplicação de dois níveis de pressão positiva e dos exercícios com carga inspiratória na função pulmonar, força muscular inspiratória e resistência muscular respiratória e na prevalência de atelectasia após gastroplastia. Métodos : Ensaio clínico, randomizado e cego, com sujeitos submetidos à cirurgia bariátrica, alocados em dois grupos: grupo pressão positiva, que recebeu pressão positiva em dois níveis, durante uma hora e fisioterapia respiratória convencional e grupo carga inspiratória, que realizou exercícios com carga linear pressórica inspiratória, seis séries de 15 repetições, além da fisioterapia respiratória convencional, sendo ambos aplicados duas vezes no pós-operatório imediato e três vezes ao dia no primeiro dia de pós-operatório. Foram realizados espirometria para análise da função pulmonar, pressão inspiratória nasal para força muscular inspiratória e teste incremental de resistência muscular respiratória para pressão inspiratória máxima sustentada, no pré-operatório e no dia da alta hospitalar, no segundo dia de pós-operatório. Resultados : Não houve diferença significativa (p>0,05) no volume de reserva expiratório e no volume corrente no pré e no pós-operatório quando comparados intra e intergrupo. Não houve diferença significativa (p>0,05) na pressão inspiratória nasal e na pressão inspiratória máxima sustentada no grupo carga inspiratória na avaliação intragrupo, mas com diferença significativa (p<0,05) comparada ao grupo pressão positiva. A prevalência de atelectasias foi de 5% em ambos os grupos sem diferença significativa (p>0,05) entre eles. Conclusão : Ambos os grupos, associados à fisioterapia respiratória convencional, preservaram o volume de reserva expiratório e o volume corrente e apresentaram baixo índice de atelectasias. O grupo carga inspiratória ainda manteve a força muscular inspiratória e a resistência dos músculos respiratórios.

Abstract Introduction. Obesity is defined as the excess of adipose tissue that deteriorates quality of life and is harmful to health. Its treatment is performed in a multidisciplinary way that ensures weight loss. The high worldwide prevalence and incidence in adolescent patients requires therapeutic interventions that are effective and safe. Bariatric surgery, as a set of surgical procedures, guarantees these characteristics, which is why it has become a valid and effective therapeutic option in patients who do not respond to conventional treatments. Objective. To determine the behavior of weight loss in patients undergoing bariatric surgery at the Hernando Moncaleano Perdomo University Hospital in Neiva, Colombia, in the years 2013 to 2016. Materials and methods. Observational, cross-sectional, retrospective study including a group of patients managed with bariatric surgery in the years 2013 to 2016 at a third level of care hospital. Results. There were 86 patients intervened with bariatric surgery, where 74.4% (64) received laparoscopic gastric bypass (LGB) and 25.6 % (22) laparoscopic gastric sleeve (LGS); 80.2 % were women with an average age of 36 years, all belonging to the subsidized Colombian health regime (64%). The most common comorbidities were osteoarticular disease (82%), arterial hypertension(36%) and type 2 diabetes (29%). There were significant differences (p = 0.003) for the initial and final BMI between two groups. It was determined that the group with the best "optimal" result in terms of %EWL (percentage of excess weight loss) equal or greater than 50% per year, was the LGB (p = 0.026). Finally it was determined that the greatest weight loss was achieved in the group of patients undergoing LGB, with a statistically significant difference; however it is necessary to carry out analytic studies that confirm these results Conclusions: A progressive decrease in weight was evidenced in both groups in the follow-up year; however the LGBgroup achieved better statistically significant results in terms of %EWL per year compared to the LGS group, data that correlates with the global trend in terms of this type of interventions.

Perfil dos pacientes submetidos à cirurgia plástica pós-bariátrica / Post-bariatric plastic surgery patients profile

Introdução: estudos que relacionam qualidade de vida com abdominoplastia demonstram aspectos positivos na vida desses pacientes. O abdômen é uma das cirurgias mais solicitadas após grande perda ponderal. E as cirurgias devem ser indicadas individualizadas. Objetivo: avaliar qual perfil dos pacientes submetidos à abdominoplastia pós-bariátrica no C-HUPES no período de 2008-2015 e comparar dados dos prontuários do C-HUPES com dados disponibilizados pelo DATASUS. Metodologia: trata-se de um estudo observacional, transversal realizado em um hospital universitário no estado da Bahia. Após seleção dos pacientes os dados foram coletados dos prontuários e instrumentos de avaliação padronizados foram aplicados durante avaliação no ambulatório. Foi realizada ainda coleta de dados e estudo de série temporal com dados agregados e secundários oriundos do sistema DATASUS e do Sistema de Informações Hospitalares/SIH. Foram analisadas todas as cirurgias bariátricas e pós-bariátricas realizadas no estado da Bahia no mesmo período de coleta do C-HUPES no período de 2008 a 2015. Resultado: o peso no período da dermolipectomia variou entre 55,4 e 111,8 kg (média de 86,361 Kg) apresentando cerca de 50 kg a menos que antes da gastroplastia. Na avaliação pós-operatória no ambulatório foi constatado uma média de idade de 49 anos, A altura da cicatriz com relação ao púbis foi de 9,1 cm e foi observada uma pequena assimetria entre a distância da extremidade da cicatriz e o eixo central variando de 0 a 6 cm. A média do comprimento da cicatriz horizontal foi de 57,8 cm. Conclusão: identificado uma demanda muito grande de pacientes que necessitam de tratamento pós-gastroplastia. As pacientes são operadas com idade diferente do esperado pela idade das gastroplastias, houve pouco ganho de peso no pós-operatório tardio mesmo operando pacientes com IMC elevado. Foi identificado o uso de códigos de dermolipectomias não estéticas quando poderia ser usado o de cirurgia pós-bariátrica onerando o custo com internamento hospital.

Introduction: studies that relate quality of life with abdominoplasty demonstrate positive results in patients' quality of life. The abdomen is one of the most requested surgeries after major weight loss. Propouse: the aim of this study was to evaluate the profile of patients who underwent post-bariatric abdominoplasty from C-HUPES in the period 2008-2015 and to compare these data from C-HUPES with data provided by DATASUS. Methodology: the cross-sectional, observational study performed at a university hospital in the state of Bahia. After the selection of the patients the data were collected from the medical records and the standardized evaluation instruments were applied during the outpatient evaluation. We also performed data collection and time series study with aggregated and secondary data from the DATASUS system and the Hospital Information System / SIH. All bariatric and post-bariatric surgeries performed in the state of Bahia without period of collection at C-HUPES Hospital from 2008 to 2015 were analyzed. Results: weight without period of dermolipectomy ranged from 55.4 to 111.8 kg ( Average of 86.361 kg) presenting about 50 kg less than before gastroplasty. In the postoperative evaluation without ambulatory, an average age of 49 years was observed. The height of the scar with respect to the pubis was of 9.1 cm and a small asymmetry was observed between the distance between the ends of the scar and the central axis of the scar. 0 to 6 cm. The mean horizontal scar length was 57.8 cm. Conclusion: a very large need was identified for patients requiring treatment after gastroplasties. As patients are operated at age and different from expected by the age of gastroplasty, there was some weight gain without late postoperative even when operating with patients with high imc. It was identified as the use of non-esthetic dermolipectomy codes where the postoperative surgery could be used in the hospital

Variações dos níveis de ferro e ferritina séricas em pós-operatório tardio de cirurgia de Fobi-Capella: estudo retrospectivo com 862 pacientes / Variations of seric iron and ferritin levels in late postoperative course of Fobi-Capella procedure: a retrospective study with 862 patients

Introdução: No pós-operatório de pacientes submetidos à cirurgia bariátrica, o comportamento do ferro e ferritina séricos são pouco estudados. O objetivo deste estudo foi avaliar a evolução dos níveis séricos destas variáveis no pós-operatório de pacientes submetidos à cirurgia bariátrica. Método: Estudo retrospectivo incluindo pacientes submetidos à cirurgia bariátrica no período de janeiro de 2011 a dezembro de 2013. Foram excluídos pacientes menores de 18 anos, não submetidos à técnica do by-pass gástrico de Fobi-Capella (em Y-de-Roux) e que não possuíam exame laboratorial no acompanhamento ambulatorial. As variáveis registradas foram sexo, idade, data da cirurgia, hemoglobina, ferro e ferritina. Foram comparados resultados com três, seis e 12 meses de pós-operatório. Utilizou-se o teste T pareado para comparação das dosagens laboratoriais ao longo do tempo. O nível de significância adotado foi de 5% (p<0,05). Resultados: Foram analisados dados relativos a 862 pacientes (573 mulheres; 66,5%) com idade mediana de 36 (18-69) anos. Não houve diferença significante ao longo do tempo estudado em relação à hemoglobina (média (DP)=13,1±1,3 g/dl no 3º mês; 13,1±1,5 g/dl no 6º mês; e 13,0±2,0 g/dl no 12º mês; p>0.05). A dosagem de ferro sérico aumentou progressivamente do 3º para o 12º mês de pósoperatório (3º mês: 82,21±26,61 mcg/dl; 6º mês: 91,42±41,00 mcg/dl e 12º mês: 99,79±38,94 mcg/dl; p<0,001). Contrariamente, houve queda da ferritina sérica ao longo do período estudado (3º mês: 234,43±242,86 ng/ml; 6º mês: 208,46±246,64 ng/ml e 12º mês: 155,21±163,08 ng/ ml;p<0.01). Conclusão: Ferro e ferritina séricos têm variações opostas no pós-operatório tardio de cirurgia bariátrica. Entretanto, essas alterações em paciente recebendo atenção nutricional não foram suficientes para determinar anemia no seguimento de até 1 ano de pós-operatório.(AU)

Introduction: The seric changes of iron and ferritin in patients submitted to bariatric procedure are seldom reported. The aim of this study was to evaluate the evolution of the levels of iron and ferritin during the late postoperative course of patients undergoing bariatric surgery. Method: Retrospective study including patients submitted to bariatric procedure from January 2011 to December 2013 with three months of follow-up. Age less of 18 years-old, procedure other than Fobi-Capella gastric by-pass (Roux-en-Y), previous hematological disorders, and lack of postoperative laboratorial exams were items of exclusion criteria. The following variables were collected: sex, age, date of the surgical procedure, hemoglobin, seric iron and ferritin. The data were collected at 3rd; 6th; and 12th postoperative month. Paired T test were used to compare the evolution of the dosages. A 5% level of significance (p<0.05) was established. Results: We analyzed the data of 862 patients ((573 females; 66.5%) with a median age of 36 (18-69) years-old. There was no difference on the hemoglobin levels along the three-time points (mean (SD)=13.1±1.3 g/dl at 3rd month; 13.1±1.5 g/dl at 6th month; and 13.0±2.0 g/dl at 12th month; p>0.05). The seric iron significantly increased from 3rd to 12th postoperative month (3rd month: 82.21±26.61 mcg/dl; 6th month: 91.42±41.00 mcg/dl and 12th month: 99,79±38,94 mcg/dl; p<0,001). Conversely, there was a fall of the seric ferritin along the study (3rd month: 234.43±242.86 ng/ml; 6th month: 208.46±246.64 ng/ml and 12th month: 155.21±163.08 ng/ml; p<0.01). Conclusion: Serum iron and ferritin have opposite variation during late postoperative of bariatric surgery. However, these alterations in patients receiving nutritional attention were not sufficient to promote anemia in the follow-up of at least one year postoperatively.(AU)
