RESUMEN
PURPOSE: The use of a nonadjustable silicone band around the gastric pouch of Roux-en-Y gastric bypass (RYGB) to reduce the recurrence of obesity is still being debated in the literature. The primary objective of this study was to evaluate banded and non-banded RYGB regarding % total weight loss (%TWL) and complications up to 10 years postoperatively and regarding the removal rate of the silicone band. MATERIAL AND METHODS: A retrospective study of the medical records of all patients submitted to banded and non-banded RYGB between 2000 and 2020 was conducted. Clinical data (age, gender, weight, body mass index-BMI, comorbidities, %TWL, and the prevalence of vomiting) and laboratory data (hemoglobin, serum iron, albumin, and vitamin B12) were obtained preoperatively and at 6 months, 1, 2, 3, 5, 7, and 10 years for both groups and at 12, 15, and 20 years after banded RYGB. RESULTS: In total, 858 patients underwent RYGB: 409 underwent banded RYGB and 449 underwent non-banded RYGB. In the preoperative period, banded RYGB patients were heavier and had higher rates of hypertension and dyslipidemia. The %TWL was higher in the banded RYGB group up to 7 years. The prevalence of vomiting is much higher in this group, which also had lower laboratory test values. Of the banded RYGB patients, 9.53% had to have the silicone ring removed after presenting complications. CONCLUSION: Banded RYGB promotes significantly higher rates of TWL at the expense of a higher frequency of food intolerance and vomiting.

Roux-en-Y gastric bypass (RYGB) and gastric sleeve (GS) have been associated with significant reductions in bone mineral density (BMD) and fluctuations in serum levels of calciotropic hormones. These changes pose a risk to bone health. The study assessed the short-term (12 and 24 months) effects of RYGB and GS on BMD and calciotropic hormones. PubMed, Embase, and Cochrane Library databases were searched. Analyses considered follow-up (12 and 24 months) with BMD as main outcome at three sites (femoral neck, total hip, and lumbar spine) and one for each calciotropic hormone (25 OH vitamin D and parathyroid hormone [PTH]). Estimated effect sizes were calculated as standardized mean differences (SMD), confidence interval of 95%, and P value. Nine studies totaling 473 participants (RYGB = 261 and GS = 212) were included. RYGB resulted in lower BMD than GS at 12 months for femoral neck (SMD = -0.485, 95% CI [-0.768, -0.202], P = .001), lumbar spine (SMD = -0.471, 95% CI [-0.851, -0.092], P = .015), and total hip (SMD = -0.616, 95% CI [-0.972, -0.259], P = .001), and at 24 months for total hip (SMD = -0.572, 95% CI [-0.907, -0.238], P = .001). At 24 months, 25 OH vitamin D was lower in RYGB than GS (SMD = -0.958 [-1.670, -0.245], P = .008) and PTH levels were higher in RYGB than in GS (SMD = 0.968 [0.132, 1.804, P = .023]). RYGB demonstrated significant reduction in regional BMD. It also induces lower serum 25 OH vitamin D and higher PTH levels than GS. The results support the need for preventive bone health measures in the short-term postoperative period, especially in the case of RYGB.

BACKGROUND: Revisional surgery is technically demanding and is usually associated with higher intraoperative and perioperative risks than primary procedures. The objective of this study is to compare outcomes of patients who had gastric bypass procedures performed as a rescue procedure for failed gastric banding, with those who had a primary gastric bypass. MATERIALS AND METHODS: The group of patients undergoing revisional gastric bypass for failed gastric band was matched in a 1:2 ratio with control patients who underwent a primary RYGB, based on gender, score, preoperative body mass index, and comorbidities. Data were retrospectively retrieved. RESULTS: Thirty one (33.3%) patients underwent band removal and gastric bypass (group A) and 62 (66.6%) only primary gastric bypass (group B). Nonsignificant differences were seen in operative time, operative bleeding, or length of stay. Complications were more frequent in group A. Postoperative weight at 12-month follow-up was greater in group A, however, not statistically significant. Changes in weight, both absolute, and percentage were not different between groups. This observation was also true for BMI, in which no significant differences were seen. Overall, mean follow-up was 16 ± 3.2 months. CONCLUSION: Gastric bypass can be performed as revisional bariatric surgery, with low complication rates and acceptable outcomes, though not with the same safety as a primary procedure. Gastric bypass is a satisfactory option for patients with a failed gastric band.

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.

The authors evaluated, retrospectively, the endoscopic sleeve gastroplasty impact in seven HIV patients, regarding effectiveness and safety outcomes. The mean baseline body mass index (BMI) was 33.76 kg/m2. The mean baseline CD4+ cell count was 690.43 cells/mm3, and the baseline viral load was undetectable. After 6 months, absolute weight loss, percentage of excess weight loss, percentage total weight loss, and BMI reduction were 20.2 ± 2.6 kg, 85.5 ± 11.1%, 21.3 ± 2.4%, and 7.1 ± 0.8 kg/m2, respectively. No patients presented severe adverse events. After 6 months, the viral load remained undetectable and the mean CD4+ cell count was 710.57 cells/mm3. The endoscopic sleeve gastroplasty is an effective and safe procedure to perform in obese HIV patients.

BACKGROUND: Endoscopic sleeve gastroplasty (ESG) is an option for patients with Class I and II obesity or patients who refuse to undergo a laparoscopic bariatric surgery. The aims of this study are as follows: (1) to demonstrate a short-term outcome after primary ESG and (2) to compare the effectiveness of weight loss between Class I and Class II obesity patients. METHODS: Patients undergoing ESG at four bariatric centers in Brazil between April 1, 2017 and December 31, 2018 were prospectively enrolled in the study (BMI 30.0-39.9 kg/m2). ESG was performed using Overstitch (Apollo Endosurgery, Austin, TX). Descriptive analysis, t test, Chi-square test, and Mann-Whitney test were used to present the results. RESULTS: A total of 233 patients underwent primary ESG. The mean age and BMI of the patients were 41.1 years and 34.7 kg/m2, respectively. Following ESG, the mean percentage of total weight loss (TWL) was 17.1% at 6 months and 19.7% at 12 months. Percentage of excess BMI loss (EBMIL) was 47.3% at 6 months and 54.8% at 12 months after ESG. The mean EBMIL was significantly greater among patients with Class I obesity than those with Class II obesity at 6 (51.1% vs. 43.7%) and 12 months (60.2% vs. 49.2%). One patient experienced bleeding during the procedure that was managed with sclerotherapy. CONCLUSION: Short-term results suggest that ESG is a safe and effective option for patients with Class I and II obesity.

BACKGROUND AND AIMS: Obesity is a pandemic affecting approximately 700 million adults worldwide, with an additional 2 billion overweight. Endoscopic sleeve gastroplasty (ESG) is a minimally invasive endoscopic bariatric therapy that involves remodeling of the greater curvature in an effort to reduce gastric capacity and delay gastric emptying. A variety of ESG suture patterns has been reported. This study is the first to use a uniform "U" stitch pattern across all centers to simplify technical aspects of the procedure and limit cost. This also uniquely assessed outcomes in all body mass index (BMI) categories and changes in metabolic rate, lean body mass, and adipose tissue composition. METHODS: This is a multicenter analysis of prospectively collected data from 7 centers including patients with overweight and obesity who underwent ESG. Primary outcomes included absolute weight loss, percent total body weight loss (%TWL), change in BMI, and percent excess weight loss (%EWL) at 6 and 12 months in overweight and obese classes I, II, and III. Secondary outcomes included adipose tissue, lean body mass reduction, and metabolic rate analyzed by bioimpedance. Additionally, immediate or delayed adverse events (AEs) were analyzed. Clinical success was defined as achieving ≥25% EWL at 1 year with ≤5% serious AE (SAE) rate following the American Society for Gastrointestinal Endoscopy (ASGE)/American Society for Metabolic and Bariatric Surgery (ASMBS) threshold. RESULTS: A total of 193 patients underwent ESG during the study period. All groups had >10% TWL and >25% EWL at 6 months of follow-up. On average, %TWL was 14.25% ± 5.26% and 15.06% ± 5.22% and the %EWL 56.15% ± 22.93% and 59.41% ± 25.69% at 6 months and 1 year of follow-up, respectively. %TWL was 8.91% ± .3%, 13.92% ± 5.76%, 16.22% ± 7.69%, and 19.01% ± .95% and %EWL 56.21% ± 2.0%, 62.03% ± 27.63%, 54.13% ± 23.46%, and 46.78% ± 2.43% for overweight and obesity classes I, II, and III, respectively, at 1 year. Male sex, age <41 years, and higher BMI were predictors of achieving a TWL ≥10% at 1-year follow-up. There was a significant reduction in adipose tissue from baseline. SAEs occurred in 1.03%, including 2 perigastric collections needing surgery. CONCLUSIONS: ESG appears to be feasible, safe, and effective in the treatment of patients with overweight and obesity according to ASGE/ASMBS thresholds.

INTRODUCTION: Obesity is a pandemic associated with significant comorbidities such as type 2 diabetes (T2DM). RYGB is an effective treatment modality for obesity and T2DM. However, bariatric surgery is currently limited to a relatively small population of patients. The duodenal-jejunal bypass sleeve (DJBS) has recently emerged as a promising therapy for obesity and T2DM by providing similar physiological effects to RYGB. We describe a case of a patient with a previously placed DJBS presenting with abdominal pain from anchor erosion managed with an endoscopic approach. METHODS: A 58-year-old man with obesity and T2DM who had failed prior medical therapy for obesity was referred for DJBS placement. This was placed without complications. At 8 weeks follow-up, he developed abdominal pain and vomiting prompting immediate endoscopic evaluation. RESULTS: EGD revealed an anchor erosion resulting in mild stenosis of the pylorus. Additionally, hyperplastic tissue was found to be adhered to the device in the duodenal bulb. Endoscopic removal with balloon dilation was unsuccessful, and a stent was placed in a "stent-in-stent" fashion through the sleeve to compress the area of tissue ingrowth encouraging local tissue necrosis and device extraction. At 15 days follow-up, the stent was removed; however, the DJBS remained adhered and immobile. Next, the ingrowing hyperplastic tissue was resected in a piecemeal fashion. This resulted in mobilization of the sleeve anchors in the duodenal bulb and successful removal of the DJBS. CONCLUSIONS: DJBS endoscopic removal is safe and effective even in challenging cases, thus preventing the need for surgical intervention.

BACKGROUND AND STUDY AIMS: Ring complications after a banded Roux-en-Y gastric bypass (RYGB) are usually managed surgically. The aim of this study was to analyze the safety and effectiveness of endoscopic removal of noneroded rings after banded-RYGB, by inducing intragastric erosion of the ring using a self-expandable plastic stent (SEPS). PATIENTS AND METHODS: A total of 41 patients with banded RYGB who had noneroded rings and food intolerance were prospectively enrolled. Patients were treated with endoscopic SEPS placement and ring removal. Data from time of stenting, resolution of symptoms, need for endoscopic dilation, and complications were recorded. RESULTS: Successful ring removal was possible in all patients. In 21 cases, the SEPS induced complete erosion, and in 17 cases the ring was removed a month later because of incomplete erosion at the time of SEPS removal. Nine patients (22.0â%) needed endoscopic dilation after stent removal in order to treat fibrotic strictures. Food tolerance was observed in 32 patients (78.0â%) after the procedure. No patient needed surgery and there were no deaths. CONCLUSIONS: Endoscopic removal of the ring using SEPS appeared to be safe and effective after a banded RYGB.

OBJECTIVE: To analyze the late results of advanced Chagasic megaesophagus treatment by esophagectomy associated with the use of proton pump inhibitor (omeprazole) as for the incidence of esophagitis and Barrett's esophagus in the remaining stump. METHODS: We studied patients with advanced megaesophagus undergoing esophagectomy and transmediastinal esophagogastroplasty. Patients were divided into three groups: A (20) with esophageal replacement by full stomach, without the use of omeprazole; B (20) with esophageal replacement by full stomach, with omeprazole 40 mg/day introduced after the first postoperative endoscopy and maintained for six years; and C (30) with esophageal replacement by gastric tube with use of omeprazole. Dysphagia, weight loss and BMI were clinical parameters we analyzed. Upper gastrointestinal endoscopy was performed in all patients, and determined the height of the anastomosis, the aspect of the mucosa, with special attention to possible injuries arising from gastroesophageal reflux, and the patency of the esophagogastric anastomosis. RESULTS: We studied 50 patients, 28 males (56%) and 22 (44%) females. All underwent endoscopy every year. In the first endoscopy, erosive esophagitis was present in nine patients (18%) and Barrett's esophagus, in four (8%); in the last endoscopy, erosive esophagitis was present in five patients (8%) and Barrett's esophagus in one (2%). When comparing groups B and C, there was no evidence that the manufacturing of a gastric tube reduced esophagitis and Barrett's esophagus. However, when comparing groups A and C, omeprazole use was correlated with reduction of reflux complications such as esophagitis and Barrett's esophagus (p <0.005). CONCLUSION: The use of omeprazole (40 mg/day) reduced the onset of erosive esophagitis and Barrett's esophagus during the late postoperative period.

Objetivo : analisar os resultados tardios do tratamento do megaesôfago chagásico avançado através da esofagectomia associada ao IBP (omeprazol), com vistas à incidência de esofagite e esôfago de Barrett do coto esofagiano remanescente. Métodos : foram estudados pacientes com megaesôfago avançado submetidos à esofagectomia e à esofagogastroplastia transmediastinal posterior. Os pacientes foram distribuídos em três grupos: A (20) com substituição esofagiana por meio do estômago total, sem o uso do omeprazol; B (20) com substituição esofagiana por meio do estômago total, sem o uso do omeprazol durante este período; após a primeira endoscopia, realizada no pós-operatório, foi introduzido IBP (omeprazol 40mg/dia) e mantido por seis anos; e C (30) com substituição esofagiana por meio do tubo gástrico com uso do omeprazol. A disfagia, a perda ponderal e o IMC foram os parâmetros clínicos analisados. A endoscopia digestiva alta foi realizada em todos os pacientes. Foi determinada a altura da anastomose, a aparência do aspecto da mucosa, com especial atenção para possíveis lesões oriundas de refluxo gastresofágico, a patência da anastomose esofagogástrica. Resultados : na primeira endoscopia, a esofagite erosiva esteve presente em nove pacientes (18%) e o esôfago Barrett, em quatro (8%); na última endoscopia, a esofagite erosiva esteve presente em quatro pacientes (8%) e o esôfago de Barrett em um (2%). Comparando-se os grupos B e C, não houve redução da esofagite e do esôfago de Barrett. Porém, comparando-se os grupos A e C, houve redução de complicações do refluxo, como esofagite e o esôfago de Barrett (p<0,005). Conclusão : os resultados obtidos permitem concluir que o uso de omeprazol (40mg/dia) reduziu o aparecimento de esofagite erosiva e esôfago de Barrett no decorrer do pós-operatório tardio.

BACKGROUND: Obesity is a public health problem, for which the prevalence has increased worldwide at an alarming rate, affecting 1.7 billion people in the world. OBJECTIVE: To describe the technique employed in incomplete penetration of gastric band where endoscopic management and/or primary closure is not feasible. MATERIAL AND METHODS: Laparoscopic removal of gastric band was performed in five patients with incomplete penetrance using Foley catheterization in the perforation site that could lead to the development of a gastro-cutaneous fistula. CLINICAL CASES: The cases presented include a leak that required surgical lavage with satisfactory outcome, and one patient developed stenosis 3 years after surgical management, which was resolved endoscopically. In all cases, the penetration site closed spontaneously. DISCUSSION: Gastric band erosion has been reported in 3.4% of cases. The reason for inserting a catheter is to create a controlled gastro-cutaneous fistula, allowing spontaneous closure. CONCLUSIONS: Various techniques have been described: the totally endoscopic, hybrid techniques (endoscopic/laparoscopic) and completely laparoscopic. A technique is described here that is useful and successful in cases where the above-described treatments are not viable.

INTRODUÇÃO Os pacientes ex-obesos necessitam de uma abordagem complexa, diante do grande excesso de pele decorrente da perda ponderal. Em alguns casos, muitas cirurgias plásticas são necessárias, não havendo uma padronização na associação destas cirurgias. No segmento superior do corpo, a região dos braços, a lateral do tórax e as mamas normalmente são acometidas, principalmente nas mulheres. Diversas técnicas foram desenvolvidas com o objetivo de alcançar resultados melhores e com cicatrizes mais escondidas. Algumas técnicas podem ser associadas, sendo realizadas em um único tempo cirúrgico. Quando a equipe é bem estruturada, o tempo cirúrgico é reduzido, significando mais segurança para o paciente. MÉTODO: Os autores apresentam uma técnica que oferece padronização no tratamento do ex-obeso, que é realizada em tempo único: a Mamoplastia (pela técnica de Pitanguy ou com aposição de prótese mamária), a Toracoplastia (com a retirada do excesso de pele na lateral do tórax) e a Braquioplastia (realizada com um desenho retilíneo na parte mais inferior dos braços). RESULTADOS: Os sete casos foram avaliados quanto ao tempo cirúrgico, à localização das cicatrizes, à forma final e à simetria. Entre as complicações, houve deiscências parciais (14%) e cicatrizes hipertróficas (14%). O resultado estético foi satisfatório para os pacientes em 84% dos casos, sendo que a qualidade da cicatrização do paciente, queloide ou cicatrizes hipercrômicas, foi a maior causa de insatisfação. CONCLUSÃO: A utilização da técnica de Toracobraquio-mamoplastia em um único tempo se mostrou efetiva no tratamento do ex-obeso, oferecendo mais uma opção, diante das outras cirurgias que estes pacientes normalmente necessitam.
INTRODUCTION Ex-obese patients require a complex surgical approach because of the large amount of excess skin due to their massive weight loss. In some cases, several plastic surgeries are needed, and there is no existing standard in the coordination of these surgeries. In the upper segment of the body, the arms, side of the thorax, and breasts are usually affected, mainly in women. Several techniques have been developed with the aim of achieving better results with better hidden scars. Some techniques may be associated, being carried out in a single surgical procedure. A well-structured surgical team leads to a reduced surgical time, which means higher safety for the patient. METHOD: We present a technique for standardization in the treatment of ex-obese patients that is performed in a single step, comprising mammoplasty (according to Pitanguy's technique or with placement of breast prosthesis), thoracoplasty (with the removal of excess skin on the side of the chest), and brachioplasty (performed with a rectilinear drawing at the lowest part of the arms). RESULTS: Seven cases were evaluated in terms of surgical time, location of the scars, and final shape and symmetry. The complications included partial dehiscence (14%) and hypertrophic scars (14%). The aesthetic result was satisfactory for 84% of the patients; on the other hand, the quality of cicatrization, keloid, and hypertrophic scars were the major causes of dissatisfaction. CONCLUSION: The use of the thoracobrachio-mammoplasty technique in a single surgical time was effective in the treatment of ex-obese patients, offering yet another option among other surgeries that these patients usually need.

BACKGROUND: Despite the weight loss benefits of bariatric surgery, studies have shown considerably compromised nutritional conditions, particularly in relation to bone metabolism, in patients who have undergone this procedure. The goal of this study was evaluate bone metabolism alterations after gastroplasty through the concentrations of carboxy-terminal cross-linking telopeptides of type-I collagen (CTX) and bone-specific alkaline phosphatase (BSAP) and vitamin D status. METHODS: This study, conducted at the Botucatu School of Medicine University Hospital, UNESP, analyzed 22 women with body mass index (BMI) values higher than 35 kg/m(2) who had undergone Roux-en-Y gastric bypass (RYGB) surgery, prior to and 3 and 6 months after the procedure. RESULTS: The patients were evaluated in relation to their anthropometric profile. Obese patients showed a vitamin D status that was compatible with moderate depletion, thus correlating negatively with parathyroid hormone (PTH) and positively with CTX. After surgery, 25-hydroxyvitamin D [25(OH)D] and CTX concentrations increased significantly. Other tests (calcium, phosphorus, magnesium, total AP and BSAP, and PTH) did not differ between the times of analysis and remained stable within the range of normality. Body fat correlated only with 25(OH)D concentrations and was inversely proportional to their increase. There was a positive correlation between PTH and CTX prior to surgery. CONCLUSIONS: Hypovitaminosis D is prevalent in obese individuals, and RYGB is related to CTX increase without BSAP alteration in the first follow-up semester.

INTRODUÇÃO: Os cirurgiões plásticos têm recebido em seus consultórios e ambulatórios um número cada vez maior de pacientes com queixa de deformidade do contorno corporal após maciças perdas ponderais secundárias a cirurgias bariátricas. Todavia, em função das restrições alimentares e disabsorções cirúrgicas, são frequentes complicações metabólicas e distúrbios nutricionais no pós-operatório tardio das gastroplastias. O objetivo deste estudo é detectar a prevalência dos principais distúrbios nutricionais relacionados à cicatrização em pacientes de ambulatório especializado em cirurgia plástica do paciente pós-gastroplastia. MÉTODO: é um estudo observacional, transversal e descritivo, em que os pacientes foram avaliados clinicamente e através de protocolo laboratorial. RESULTADOS: foram avaliados 32 pacientes com gastroplastia há pelo menos dois anos e estabilidade ponderal há no mínimo seis meses. Os principais distúrbios detectados foram: anemia (56% dos pacientes), com carências na bioquímica do ferro (31,2%) e da vitamina B12 (25%), bem como deficiências dos íons zinco (18,7%) e cobre (3,1%). Houve carências discretas no perfil proteico e ausência de déficits na bioquímica básica e lipidograma. CONCLUSÃO: é dever do cirurgião plástico conhecer a fundo a prevalência dos principais distúrbios nutricionais relacionados à cicatrização na população de pacientes pós-gastroplastia no sentido de corrigir eventuais carências e prevenir complicações. Sabe-se, contudo, que ainda são necessários mais estudos para correlacionar qualquer deficiência alimentar às intercorrências observadas no pós-operatório deste grupo de pacientes.
INTRODUCTION: Plastic surgeons have received in their outpatient clinics an increasing number of patients complaining of body contour defects due to the massive weight loss after a bariatric surgery. However, owing to dietary restrictions and surgical desorption, metabolic complications and nutritional disorders are commonly observed in the late postoperative period after gastroplasty. The aim of this study was to determine the prevalence of major nutritional disorders related to healing in patients at a specialized outpatient plastic surgery clinic who underwent gastroplasty. METHOD: This is an observational, transversal, and descriptive study, in which a laboratory protocol was used to clinically evaluate and assess the patients. RESULTS: Thirty-two patients who underwent gastroplasty at least 2 years previously with weight stability for at least 6 months were evaluated. The major disorders identified included anemia (56% of patients) and deficiency in iron (31.2%), vitamin B12 (25%), zinc ions (18.7%), and copper (3.1%). Mild deficiencies in the protein profile were also observed; however, no deficiencies in basic and lipid biochemistry were noted. CONCLUSION: The plastic surgeon should have an in-depth knowledge about the prevalence of the major nutritional disorders related to healing in postbariatric patients, to allow correction of possible deficiencies and prevention of complications. However, more studies would be required to correlate any dietary deficiency to the complications observed in the postoperative period in this group of patients.
