Endoscopic and histopathological assessment of individuals undergoing one anastomosis gastric bypass: a 2-year follow-up.

BACKGROUND: There is much debate over the occurrence of biliary reflux to the gastric pouch after one anastomosis gastric bypass (OAGB) and its potential risks. OBJECTIVE: To assess endoscopic and histopathological findings following a standardized protocol of biopsy collection two years after OAGB. METHODS: A historical cohort study was conducted, based on a prospectively collected database, which involved 39 participants who underwent OAGB. Participants underwent clinical evaluation and esophagogastroduodenoscopy at the time of surgery and 24 months afterward. Post-operatively, biopsy specimens in esophagogastric junction, pouch, and anastomosis were systematically collected. RESULTS: 92.3% of the participants were female and the mean age was 37 ± 8.5 years. The mean body mass index (BMI) significantly decreased from 37.6 ± 5.7 kg/m2 to 27 ± 4.1 kg/m2 after 2 years (p < 0.001). The mean %TWL was 27.2 ± 10.5%. The prevalence of non-erosive gastritis significantly increased from 25.6 to 51.3% (p = 0.02). Erosive gastritis significantly decreased from 28.2 to 10.3% (p = 0.04). Four cases of marginal ulcers were identified (10.3%). The commonest histopathological finding was mild inflammation in 74.3% (esophagogastric junction), 58.9% (pouch), and 71.8% (anastomosis). There was one case of focal intestinal metaplasia in each site of interest and no cases of dysplasia or severe inflammation. CONCLUSIONS: Using a standardized protocol of post-operative biopsy collection, low rates of severe endoscopic and histopathological abnormalities were observed two years after OAGB. Nevertheless, as most patients have histologically proven inflammation, bile in the gastric pouch, and endoscopic gastritis, long-term surveillance is essential because of the uncertain risk of these abnormalities.

Effects of bariatric surgery on renal function: a retrospective cohort study comparing one-year outcomes between one-anastomosis gastric bypass and Roux-en-Y gastric bypass.

BACKGROUND: Evidence on the effect of one-anastomosis gastric bypass (OAGB) on renal function is limited. OBJECTIVE: To compare the evolution of estimated renal function observed 1 year after OAGB and Roux-en-Y gastric bypass (RYGB) in individuals with obesity. DESIGN AND SETTING: Observational, analytical, and retrospective cohort study. Tertiary-level university hospital. METHODS: This study used a prospectively collected database of individuals who consecutively underwent bariatric surgery. Renal function was assessed by calculating the estimated glomerular filtration rate (eGFR), according to the Chronic Kidney Disease Epidemiology Collaboration. The one-year variation in the eGFR was compared between the procedures. RESULTS: No significant differences in age, sex, obesity-associated conditions, or body mass index were observed among individuals who underwent either OAGB or RYGB. OAGB led to a significantly higher percentage of total (P = 0.007) and excess weight loss (P = 0.026). Both OAGB and RYGB led to significantly higher values of eGFR (103.9 ± 22 versus 116.1 ± 13.3; P = 0.007, and 102.4 ± 19 versus 113.2 ± 13.3; P < 0.001, respectively). The one-year variation in eGFR was 11 ± 16.2% after OAGB and 16.7 ± 26.3% after RYGB (P = 0.3). Younger age and lower baseline eGFR were independently associated with greater postoperative improvement in renal function (P < 0.001). CONCLUSION: Compared with RYGB, OAGB led to an equivalent improvement in renal function 1 year after the procedure, along with greater weight loss.

WEIGHT LOSS AND QUALITY OF LIFE AFTER ONE ANASTOMOSIS GASTRIC BYPASS: A 2-YEAR FOLLOW-UP STUDY.

•One anastomosis gastric bypass (OAGB) led to significant weight loss after 2 years. •OAGB associated was well-succeeded in regards to weight loss in most individuals. •OAGB led to significant improvement of quality of life (QoL) assessed by the BAROS system. •"Self-steem" and "work capacity" were the most positively affected QoL domains after OAGB. Background - Studies assessing quality of life (QoL) after one anastomosis gastric bypass (OAGB) are currently scarce. Objective - To analyze the main weight loss outcomes and QoL in individuals undergoing OAGB during a 2-year follow-up. Methods - This is a retrospective study based on a prospectively collected database including individuals which underwent OAGB at a tertiary-level university hospital. After 2-years, excess weight loss was assessed, and post-surgical therapeutical success was determined using Reinhold's criteria. QoL was assessed through the Bariatric Analysis and Reporting Outcomes System (BAROS). Results - Out of 41 participants, 90.2% were female and the average age was 38±8.3 years old. The average body mass index significantly decreased from 37.1±5.6 kg/m2 to 27±4.5 kg/m2 after 2-years (P< 0.001). The mean percentage of excess weight loss was 84.6±32.5%. Regarding weight loss outcomes, 61% were considered "excellent", while 26.8% were "good" according to Reinhold's criteria. With regards to QoL assessed by BAROS, most individuals achieved a score classified as either "excellent" (26.8%), "very good" (36.6%), or "good" (31.7%). The highest degrees of satisfaction achieved were in the domains "self-esteem" and "work capacity", in which 75.6% and 61%, respectively, were classified as "much better". Conclusion - OAGB associated with significant weight loss and resolution of obesity-related medical conditions, as well as relevant QoL improvement assessed by the BAROS system.

Brazilian national bariatric registry - pilot study.

INTRODUCTION: Brazil is a world leader in bariatric surgery. However, the actual number of surgeries performed in the country is still unknown. It is necessary to implement an instrument to monitor the quality of care provided. This study evaluated the implementation of a Bariatric Surgery Data Registry in Brazil. METHODOLOGY: the registry was developed with Dendrite Clinical Systems Ltd., with data collected prospectively on an internet-based software. Seven centers were selected based on surgical volume and data entry commitment. The project covered three years after system implementation. RESULTS: 1,363 procedures performed by 17 surgeons were included. Most patients were female (67.2%), with average age of 39 years old and average baseline BMI of 41.5kg/m2. Diabetes mellitus was present in 34.5%, and hypertension in 40.1%. Roux-en-Y gastric bypass was performed in 79.3%, 95.5% by laparoscopy. There was one in-hospital death of cardiovascular cause. The average hospital stay was 2.03 days. The surgery-related complication rate was 0.97% in the first month, with three reoperations. Short-term follow-up was recorded in 75.6% and one-year follow-up in 21.64%. Total body weight loss was 10% in 30 days, rising to 33.3% after one year, with no difference between surgical techniques. CONCLUSIONS: the population profile was in accordance with the global registry of the International Federation for the Surgery of Obesity and Metabolic Disorders. The main difficulty encountered was low postoperative data entry. The experience acquired in this project will help advance data collection and knowledge of the safety and effectiveness of bariatric surgery in Brazil.

Trajectory of NAFLD characteristics after Roux-en-Y gastric bypass: a five-year historical cohort study.

BACKGROUND: The long-term effects of bariatric surgery on the course of non-alcoholic fatty hepatopathy (NAFLD) are not fully understood. OBJECTIVE: To analyze the evolution of NAFLD characteristics through noninvasive markers after Roux-en-Y gastric bypass (RYGB) over a five-year period. DESIGN AND SETTING: Historical cohort study; tertiary-level university hospital. METHODS: The evolution of NAFLD-related characteristics was evaluated among 49 individuals who underwent RYGB, with a five-year follow-up. Steatosis was evaluated through the hepatic steatosis index (HSI), steatohepatitis through the clinical score for non-alcoholic steatohepatitis (C-NASH) and fibrosis through the NAFLD fibrosis score (NFS). RESULTS: 91.8% of the individuals were female. The mean age was 38.3 ± 10 years and average body mass index (BMI), 37.4 ± 2.3 kg/m2. HSI significantly decreased from 47.15 ± 4.27 to 36.03 ± 3.72 at 12 months (P < 0.01), without other significant changes up to 60 months. C-NASH significantly decreased from 0.75 ± 1.25 to 0.29 ± 0.7 at 12 months (P < 0.01), without other significant changes up to 60 months. NFS decreased from 1.14 ± 1.23 to 0.27 ± 0.99 at 12 months (P < 0.01), and then followed a slightly ascending course, with a marked increase by 60 months (0.82 ± 0.89), but still lower than at baseline (P < 0.05). HSI variation strongly correlated with the five-year percentage total weight loss (R = 0.8; P < 0.0001). CONCLUSION: RYGB led to significant improvement of steatosis, steatohepatitis and fibrosis after five years. Fibrosis was the most refractory abnormality, with a slightly ascending trend after two years. Steatosis improvement directly correlated with weight loss.

The IFSO Worldwide One Anastomosis Gastric Bypass Survey: Techniques and Outcomes?

INTRODUCTION: One anastomosis gastric bypass (OAGB) has become one of the most commonly performed gastric bypass procedures in some countries. OBJECTIVES: To assess how surgeons viewed the OAGB, perceptions, indications, techniques, and outcomes, as well as the incidence of short- and long-term complications and how they were managed worldwide. METHODS: A questionnaire was sent to all IFSO members in all 5 chapters to study the pattern of practice and outcomes of OAGB. RESULTS: Seven hundred and forty-two surgeons responded. The most commonly performed procedures were sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and OAGB. Preoperatively, 70% of the surgeons performed endoscopy routinely. In regards to weight loss, 83% (570 surgeons) responded that OAGB produces better weight loss than SG, and 49% (342 surgeons) responded that OAGB produces better weight loss than RYGB. The most common length of the biliopancreatic limb (BPL) utilized was 200 cm. Sixty-seven percent of surgeons did not measure the total length of the small bowel. In patients with reflux disease and history of smoking, 53% and 22% of surgeons respectively still offered OAGB as a treatment option. Postoperatively, leak was documented in 963 patients, and it was the leading cause for mortality. Leak management was conservative in 35%. Conversion to RYGB was performed in 31%. In 16% the anastomosis was reinforced, 6% of the patients were reversed, and other procedures were performed in 12%. Revision of OAGB for malnutrition/steatorrhea or severe bile reflux was reported at least once by 37% and 45% of surgeons, respectively (200 cm was the most commonly encountered biliopancreatic limb BPL in those revised for malnutrition). Most common strategy for revision was conversion to RYGB (43%), reversal to normal anatomy (32%), shortening of the BPL (20%), and conversion to SG (5%). Nevertheless, 5 out of 98 mortalities (5%) were due to liver failure/malnutrition. CONCLUSION: There are infrequent but potentially severe specific complications including malnutrition, liver failure, and bile reflux that may require surgical correction after OAGB.

Revisional surgery in severe nutritional complications after bariatric surgical procedures: report of four cases from a single institution and review of the literature.

INTRODUCTION: bariatric surgery is currently the only treatment that leads to long-term and sustained weight loss and decreased morbidity and mortality in morbidly obese individuals. Roux-en-Y bypass causes weight loss by restricting food intake associated with reduced intestinal absorption, in addition to multiple endocrine and satiogenic effects. Biliopancreatic diversion promotes weight loss mainly due to poor absorption of the nutrients ingested. Both procedures exclude parts of the gastrointestinal tract. OBJECTIVE: to describe four cases of revisional surgery after primary bariatric surgery, due to serious nutritional complications, and to review the literature regarding this subject. METHODS: a retrospective analysis of patients of Unicamps bariatric center database and review of the literatures were performed. RESULTS: four patients were identified, 2 women and 2 men, with a mean age of 48 years. The mean body mass index before revisional surgery was 23.7 kg/m2. Three patients underwent Scopinaro biliopancreatic diversion, and onde patient underwent Roux-en-Y gastric bypass. The revisional surgeries were revision, conversion, and reversion. One patient died. For the review of the literature 12 articles remained (11 case reports and 1 case series). Another five important original articles were included. CONCLUSION: fortunately, revision surgery is rarely necessary, but when indicated it has increased morbidity, It can be revision, reverion or conversion according to the severity of the patient and the primary surgery performed.

Weight Loss and Vomiting 1 Year After Banded Versus Non-banded One Anastomosis Gastric Bypass: a Prospective Randomized Trial.

BACKGROUND: The weight loss outcomes after banded one-anastomosis gastric bypass (OAGB) remain to be determined. OBJECTIVE: To compare weight loss and vomiting 1 year after banded versus non-banded OAGB. METHODS: This is a prospective, open-label, randomized study, which evaluated 33 individuals with morbid obesity, which underwent banded (16 individuals) and non-banded OAGB (17 individuals) and were followed up for 12 months. Weight loss (percentages of total weight loss-%TWL-and excess weight loss-%EWL) and occurrence of vomiting were assessed and compared before surgery and after 6 and 12 months. RESULTS: At baseline, there were no differences between groups in regard to age, gender, and body mass index (BMI). At 6 and 12 months post-op, and the overall mean %TWL regardless of band use was 22.4 ± 7% and 29 ± 6.9%, respectively, and the overall average %EWL regardless of band use was 66.8 ± 22.9% and 86.3 ± 24%, respectively. %TWL did not differ between the banded and non-banded groups at 6 (21.8 ± 6.8% vs. 23.1 ± 7.4%; p = 0.7) and 12 months post-op (27.5 ± 6.6% vs. 30.4 ± 7.1%; p = 0.3), as well as %EWL at 6 (67 ± 22.9% vs. 67.6 ± 23.6%; p = 0.6) and 12 months post-op (83.5 ± 24.4% vs. 89 ± 24.1%; p = 0.4). The occurrence of vomiting did not significantly differ between banded and non-banded OAGB at 6 (12.5% vs. 11.8%; p = 0.9) and 12 months post-op (12.5% vs. 5.9%; p = 0.5). CONCLUSION: OAGB led to an overall satisfactory weight loss after 1 year, regardless of band use. Banded OAGB did not lead to neither significantly higher weight loss nor more vomiting than non-banded OAGB 1 year after surgery.

Does weight gain, throughout 15 years follow-up after Nissen laparoscopic fundoplication, compromise reflux symptoms control?

BACKGROUND: Gastroesophageal reflux disease is defined by the abnormal presence of gastric content in the esophagus, with 10% incidence in the Western population, being fundoplication one treatment option. AIM: To evaluate the early (six months) and late (15 years) effectiveness of laparoscopic fundoplication, the long term postoperative weight changes, as well as the impact of weight gain in symptoms control. METHODS: Prospective study of 40 subjects who underwent laparoscopic Nissen's fundoplication. Preoperatively and early postoperatively, clinical, endoscopic, radiologic, manometric and pHmetric evaluations were carried out. After 15 years, clinical and endoscopic assessments were carried out and the results compared with the early ones. The presence or absence of obesity was stratified in both early and late phases, and its influence in the long-term results of fundoplication was studied, measuring quality of life according to the Visick criteria. RESULTS: The mean preoperative ages, weight, and body mass index were respectively, 51 years, 69.67 kg and 25.68 kg/m2. The intraoperative and postoperative complications rates were 12.5% and 15%, without mortality. In the early postoperative period the symptoms were well controlled, hernias and esophagitis disappeared, the lower esophageal sphincter had functional improvement, and pHmetry parameters normalized. In the late follow-up 29 subjects were assessed. During this period there was adequate clinical control of reflux regardless of weight gain. In both time periods Visick criteria improved. CONCLUSION: Fundoplication was safe and effective in early and late periods. There was late weight gain, which did not influence effective symptoms control.

The recommendations of the Brazilian College of Surgeons and the Brazilian Bariatric and Metabolic Surgery Societies on the return of bariatric and metabolic operations in geographic regions of the country where the procedures have been allowed by local policies, in the period of COVID-19 pandemic.

Prioritizing surgical procedures aims at facilitating patient's access according to the clinical needs, maximizing access equity, and minimizing the damage from delayed access. Previous categorization of elective bariatric surgery have been adapted to define an objective prioritizing system that reflects those principles for bariatric and metabolic operations. Given the factors that contribute to the morbidity and mortality of obese and type 2 diabetes patients, surgical prioritization should be based on clinical risk stratification. For patients with type 2 diabetes, we suggest that the operation may be prioritized for those with a higher risk of morbidity and mortality in a relatively short term. Likewise, it is necessary to guide the surgical team regarding the necessary care both in the pre, per and postoperative periods of bariatric and metabolic surgery. These recommendations aim to reduce the risk of in-hospital contamination of the surgical team among health professionals and between health professionals and patients. In summary, these recommendations have been shaped after a thorough analysis of the available literature and are extremely important to mitigate the harm related to the clinical complications of obesity and its comorbidities while keeping healthcare providers' and patients' safety.

Endoscopic Argon Plasma Coagulation vs. Multidisciplinary Evaluation in the Management of Weight Regain After Gastric Bypass Surgery: a Randomized Controlled Trial with SHAM Group.

BACKGROUND: Roux-en-Y gastric bypass is one of the most widely performed bariatric surgeries. However, the relapse of obesity occurs in approximately 20% of patients and enlargement of the anastomosis is one of the factors associated with this relapse. Endoscopic treatment of the anastomosis has been proposed to assist in renewed weight loss. One endoscopic technique is the narrowing of the anastomosis argon plasma coagulation (APC). OBJECTIVE: Evaluate the effectiveness and safety of the endoscopic treatment of an enlarged anastomosis with APC. METHODS: A randomized controlled study was conducted comparing APC to exclusive multidisciplinary management after weight regain. RESULTS: Forty-two patients were divided into two groups: APC (n = 22) and control (n = 20). After 14 months of follow-up with a crossover at 6 months, significant improvement in satiety and greater weight loss were found in the APC group and after crossover. APC was associated with significant weight loss [9.73 (7.46, 12) vs. + 1.38 (- 1.39, 2.15)], a reduction in the anastomosis diameter [p < 0.001], early satiation [0.77 (0.44, 1.11) vs. - 0.59 (- 0.95, - 0.23), p < 0.001], and increased quality of life measured using the EQ5D index [p = 0.04] and EQ5D VAS scale [p = 0.04]. Considering total mean weight loss throughout the entire follow-up, weight loss was similar in both groups (13.02 kg in the APC and 11.52 kg in the control). CONCLUSION: Treatment of the gastrojejunal anastomosis with APC was effective and safe, with significant weight loss, the return of early satiation, and an improvement in quality of life.

Bariatric Surgery Offer in Brazil: a Macroeconomic Analysis of the Health system's Inequalities.

BACKGROUND: Brazil currently holds the second place in the worldwide ranking of the largest number of bariatric surgical procedures performed. The offer of bariatric surgery in the public health system is not sufficient for its demand; it remains to be determined whether the recent economic downturn affected this offer. OBJECTIVE: To analyze the proportion of bariatric surgeries performed by the public system in Brazil and assess the influence of macroeconomic variables over time. METHODS: This is a nationwide analysis which correlated the estimated number of bariatric surgeries in Brazil in both public and private health-providing systems from 2003 through 2017 with the main macroeconomic variables of Brazil during the evaluated period (gross domestic product [GDP], inflation rate, and unemployment rate), and both overall and public healthcare expenditures. RESULTS: The proportion of surgeries performed in the public system varied from 7.1% in 2014 to 10.4% in 2004. There was a significant positive correlation between the public proportion of surgeries with the unemployment rate (R = 0.55666; P = 0.03868). There were significant negative correlations between the proportion of public surgeries with the public health expenditure per capita (R = - 0.88811; P = 0.00011) and with the public percentage of healthcare expenditure per capita (R = - 0.67133; P = 0.01683). CONCLUSION: There were direct correlations between the number of public bariatric procedures and the unemployment rate, as well as with the public healthcare expenditure per capita. Despite the increase in the number of public procedures, its proportion reveals an insufficiency of the current offer of bariatric surgery provided by the public system.

EARLY WEIGHT LOSS OUTCOMES AND GLUCOSE METABOLISM PARAMETERS AFTER BANDED VERSUS NON-BANDED ONE ANASTOMOSIS GASTRIC BYPASS: A PROSPECTIVE RANDOMIZED TRIAL.

BACKGROUND: The influence of the placement of a band on the outcomes of one anastomosis gastric bypass (OAGB) has not been appropriately studied yet. OBJECTIVE: To compare early weight loss and glucose metabolism parameters following banded versus non-banded OAGB. METHODS: A prospective randomized study, which evaluated 20 morbidly obese individuals who underwent banded and non-banded OAGB and were followed-up for three months. Weight loss (percentage of excess weight loss - %EWL and percentage of body mass index loss - %BMIL) and glucose metabolism outcomes (glucose, insulin and homeostasis model assessment - HOMA) were compared. RESULTS: The banded group presented a significantly higher %EWL at one month (29.6±5.5% vs 17.2±3.4%; P<0.0001) and two months post-surgery (46±7% vs 34.2±9%; P=0.004544), as well as a significantly higher %BMIL at one month (9.7±1.1% vs 5.8±0.8%; P<0.0001), two months (15±1.4% vs 11.5±2.1; P=0.000248), and three months (18.8±1.8% vs 15.7±3.2%; P=0.016637). At three months, banded OAGB led to significant decreases of insulin (14.4±4.3 vs 7.6±1.9; P=0.00044) and HOMA (3.1±1.1 vs 1.5±0.4; P=0.00044), whereas non-banded OAGB also led to significant decreases of insulin (14.8±7.6 vs 7.8±3.1; P=0.006) and HOMA (3.2±1.9 vs 1.6±0.8; P=0.0041). The percent variation of HOMA did not significantly differ between banded and non-banded OAGB (P=0.62414); overall, the percent variation of HOMA was not correlated with %EWL (P=0.96988) or %BMIL (P=0.82299). CONCLUSION: Banded OAGB led to a higher early weight loss than the standard technique. Banded and non-banded OAGB led to improvements in insulin resistance regardless of weight loss.

Effects of bariatric surgery on renal function: a retrospective cohort study comparing one-year outcomes between one-anastomosis gastric bypass and Roux-en-Y gastric bypass

ABSTRACT BACKGROUND: Evidence on the effect of one-anastomosis gastric bypass (OAGB) on renal function is limited. OBJECTIVE: To compare the evolution of estimated renal function observed 1 year after OAGB and Roux-en-Y gastric bypass (RYGB) in individuals with obesity. DESIGN AND SETTING: Observational, analytical, and retrospective cohort study. Tertiary-level university hospital. METHODS: This study used a prospectively collected database of individuals who consecutively underwent bariatric surgery. Renal function was assessed by calculating the estimated glomerular filtration rate (eGFR), according to the Chronic Kidney Disease Epidemiology Collaboration. The one-year variation in the eGFR was compared between the procedures. RESULTS: No significant differences in age, sex, obesity-associated conditions, or body mass index were observed among individuals who underwent either OAGB or RYGB. OAGB led to a significantly higher percentage of total (P = 0.007) and excess weight loss (P = 0.026). Both OAGB and RYGB led to significantly higher values of eGFR (103.9 ± 22 versus 116.1 ± 13.3; P = 0.007, and 102.4 ± 19 versus 113.2 ± 13.3; P < 0.001, respectively). The one-year variation in eGFR was 11 ± 16.2% after OAGB and 16.7 ± 26.3% after RYGB (P = 0.3). Younger age and lower baseline eGFR were independently associated with greater postoperative improvement in renal function (P < 0.001). CONCLUSION: Compared with RYGB, OAGB led to an equivalent improvement in renal function 1 year after the procedure, along with greater weight loss.

Human hybrid NOTES transvaginal sleeve gastrectomy: initial experience.

Laparoscopic sleeve gastrectomy is gaining popularity as a treatment of morbid obesity. It is a relatively new procedure with a postoperative follow-up not exceeding 5 years. The natural orifice transluminal endoscopic surgical procedures are also gaining in popularity, and we are now experiencing the first transition from animal to human trials. We describe the first sleeve gastrectomy surgery for morbid obesity using the vagina as the natural orifice in the form of a hybrid natural orifice transluminal endoscopic surgery transvaginal sleeve gastrectomy, including the short-term outcomes and complications.

First human experience with endoscopically delivered and retrieved duodenal-jejunal bypass sleeve.

BACKGROUND: We report the first human experience with an endoscopic duodenal-jejunal bypass sleeve (DJBS) in a community hospital. METHODS: The DJBS is a 60-cm sleeve anchored in the duodenum to create a duodenal-jejunal bypass. In a 12-patient prospective, open-label, single-center, 12-week study, the device was endoscopically implanted, left in situ, and retrieved. The study included 5 men and 7 women, with a mean body mass index of 43 kg/m(2). Of the 12 patients, 4 had type 2 diabetes. The primary endpoints were the incidence and severity of adverse events. The secondary outcomes included the percentage of excess weight loss and changes in co-morbid status. RESULTS: The DJBS was endoscopically delivered and retrieved in all patients (mean implant/explant time of 26.6 and 43.3 min, respectively). Of the 12 patients, 10 were able to maintain the device for 12 weeks and 2 underwent explantation after 9 days secondary to poor device placement. Several self-limited adverse events were possibly or definitely related to the device, including 6 episodes of abdominal pain, 18 of nausea, and 16 of vomiting, mainly within 2 weeks of implantation. Two partial pharyngeal tears occurred during explantation. Implant site inflammation was encountered in all patients. No device-related event was considered severe. The average percentage of excess weight loss for the 10 patients with the device in place for 12 weeks was 23.6%, with all patients achieving at least 10% excess weight loss. All 4 diabetic patients had normal fasting plasma glucose levels without hypoglycemic medication for the entire 12 weeks. Of these 4 patients, 3 had decreased hemoglobin A(1c) of > or =.5% by week 12. CONCLUSION: The DJBS can be safely delivered and removed endoscopically and left in situ for 12 weeks. The device had a favorable safety and encouraging efficacy profile. Randomized prospective trials are warranted.

Nationwide Macroeconomic Variables and the Growth Rate of Bariatric Surgeries in Brazil.

BACKGROUND: The effect of nationwide economic issues on the necessary expansion in the number of bariatric procedures remains unclear. OBJECTIVE: This study aims to determine whether there are correlations between the growth rate in the number of bariatric surgeries and the major macroeconomic variables over time in Brazil. METHODS: It is a nationwide analysis regarding the number of bariatric surgeries in Brazil and the main national macroeconomic variables from 2003 through 2016: gross domestic product (GDP), inflation rate, and the unemployment rate, as well as the evolution in the number of registered bariatric surgeons. RESULTS: There were significant positive correlations of the growth rate of surgeries with the early variations of the GDP (R = 0.5558; p = 0.04863) and of the overall health expenditure per capita (R = 0.78322; p = 0.00259). The growth rate of the number of bariatric surgeries was not correlated with the unemployment and inflation rates, as well as with the growth rate of available bariatric surgeons. CONCLUSION: There were direct relationships between the growth rate of bariatric surgeries and the evolutions of the GDP and health care expenditure per capita. These variables appear to influence the nationwide offer of bariatric surgery.

Perda de peso e qualidade de vida após o Bypass Gástrico de Anastomose Única: resultados de um seguimento de 2 anos / Weight loss and quality of life after one anastomosis gastric bypass: a 2-year follow-up study

ABSTRACT Background: Studies assessing quality of life (QoL) after one anastomosis gastric bypass (OAGB) are currently scarce. Objective: To analyze the main weight loss outcomes and QoL in individuals undergoing OAGB during a 2-year follow-up. Methods: This is a retrospective study based on a prospectively collected database including individuals which underwent OAGB at a tertiary-level university hospital. After 2-years, excess weight loss was assessed, and post-surgical therapeutical success was determined using Reinhold's criteria. QoL was assessed through the Bariatric Analysis and Reporting Outcomes System (BAROS). Results: Out of 41 participants, 90.2% were female and the average age was 38±8.3 years old. The average body mass index significantly decreased from 37.1±5.6 kg/m2 to 27±4.5 kg/m2 after 2-years (P< 0.001). The mean percentage of excess weight loss was 84.6±32.5%. Regarding weight loss outcomes, 61% were considered "excellent", while 26.8% were "good" according to Reinhold's criteria. With regards to QoL assessed by BAROS, most individuals achieved a score classified as either "excellent" (26.8%), "very good" (36.6%), or "good" (31.7%). The highest degrees of satisfaction achieved were in the domains "self-esteem" and "work capacity", in which 75.6% and 61%, respectively, were classified as "much better". Conclusion: OAGB associated with significant weight loss and resolution of obesity-related medical conditions, as well as relevant QoL improvement assessed by the BAROS system.

RESUMO Contexto: Existem poucos estudos que analisaram a qualidade de vida (QV) após o bypass gástrico de anastomose única (BGAU). Objetivo: Analisar os principais resultados de perda de peso e QV em indivíduos submetidos ao BGAU ao longo de 2 anos de seguimento. Métodos: Este é um estudo retrospectivo baseado em um banco de dados coletado prospectivamente que incluiu indivíduos submetidos ao BGAU em um hospital universitário de nível terciário. Após 2 anos, foi analisado o percentual de perda do excesso de peso (%PEP) e o sucesso terapêutico pós-cirúrgico foi classificado através critérios de Reinhold. A qualidade de vida foi avaliada por meio do Bariatric Analysis and Reporting Outcomes System (BAROS). Resultados: Dos 41 participantes, 90,2% eram do sexo feminino e a idade média foi de 38±8,3 anos. O índice de massa corporal médio diminuiu significativamente de 37,1±5,6 kg/m2 para 27±4,5 kg/m2 após 2 anos (P<0,001). O %PEP médio foi de 84,6±32,5%. Quanto à avaliação dos resultados de perda de peso, 61% foram considerados "excelentes", enquanto 26,8% foram "bons" segundo os critérios de Reinhold. Com relação à QV avaliada pelo BAROS, a maioria dos indivíduos obteve escores classificados como "excelente" (26,8%), "muito bom" (36,6%) ou "bom" (31,7%). Os maiores graus de satisfação alcançados foram nos domínios "autoestima" e "capacidade para o trabalho", nos quais 75,6% e 61%, respectivamente, foram classificados como "muito melhor". Conclusão: O BGAU associou-se à significativa perda de peso e resolução de comorbidades, bem como melhora relevante da qualidade de vida avaliada pelo sistema BAROS.

Live surgery courses: retrospective safety analysis after 11 editions.

INTRODUCTION: Live surgery is a topic of interest at every meeting or course in the field of surgery. The potential of laparoscopy for live broadcasting makes it an excellent tool in continuing medical education. Surgeons who participate in live surgeries are usually experienced, but several conditions may influence the results and safety of a procedure. OBJECTIVES: To analyze safety and outcomes in a series of patients who underwent surgery in the last 10 years in a live surgery course at our institution. SETTING: University public hospital in Spain. METHODS: Retrospective review of patients who underwent surgery during these courses from 2006 to 2016. Morbidity, mortality, and long-term results were analyzed. RESULTS: Of 107 patients, 74 (68.5%) were women, and 38 (35.2%) had revision surgery. Five had surgery during previous editions. The most performed procedures were Roux-en-Y gastric bypass (38.9%), sleeve gastrectomy (16.7%), and duodenal switch (14%). Ten cases were endoscopic procedures. Morbidity was 13% (14 cases), and 6 required early postoperative revision (5.6%). Most of the complications were Clavien types III and I. Bleeding was the most common (72.4%). There was no anastomotic leak, but 1 duodenal stump leak occurred. During follow-up, 6 patients had a surgical complication and 5 required revision surgery. There was no mortality. DISCUSSION: We found higher morbidity and reoperation rates. The conversion rate in long-term follow-up was higher. Despite the educational benefits, we should take into consideration the higher risk to our patients for future editions.
