RESUMO
The increasing rate of obesity and life expectancy will lead to increasing numbers of bariatric procedures in the elderly. We aim to report the early (≤ 30 days) adverse events of One-Anastomosis Gastric Bypass (OAGB) in this patient population. Assuta Bariatric Centers in Israel. Retrospective review of perioperative OAGB outcomes between elderly group (≥ 65 years) and non-elderly group (18-64 years) at high-volume bariatric centers between January 2017-December 2021. Operative time, length of stay (LOS), and overall ≤ 30 days complication rates, as ranked by the Clavien-Dindo Classification (CDC) were compared. There were 6618 patients (non-elderly group) and 104 (elderly group) who underwent OAGB. Gender and preoperative BMI were comparable between the two age groups. The elderly group had significantly higher rate of ischemic heart disease and chronic renal failure. The number of patients with LOS ≥ 3 days was significantly higher in the elderly group [19.4% (n = 20) vs. 6.6% (n = 331), respectively; p < 0.001]. The total early adverse events were higher in the elderly group with no statistical significance [7.7% (n = 8) vs. 3.8% (n = 250), respectively; p = 0.062]. The rate of minor and major adverse events and reoperation rate was comparable between the two groups. The rate of readmissions was significantly higher in the elderly group 5.8% (n = 6) vs. 1.9% (n = 124), respectively p = 0.015. There was 0.06% mortality (n = 2) in the non-elderly group. OAGB is a relatively safe metabolic and bariatric surgery for elderly obese patients with early (≤ 30 days) morbidity rates similar to the non-elderly population.

BACKGROUND: Long-term outcome data for bariatric surgery in patients with severe obesity (SO) (body mass index [BMI] ï³ 50 kg/m2) are scarce. OBJECTIVES: To compare perioperative morbidity and long-term outcomes between patients with SO and non-SO (NSO). METHODS: Patients with SO who underwent primary bariatric surgery with a follow-up ï³ 5 years were age- and gender-matched with NSO patients in a retrospective, case-control study. Data included demographics, BMI, co-morbidities, early outcomes, current and nadir weight, co-morbidity status, and general satisfaction. RESULTS: Of 178 patients, 49.4% were male, mean age 44.5 ± 14 years. Mean preoperative BMI was 54.7 ± 3.6 and 41.8 ± 3.8 kg/m2 in SO and NSO, respectively (P = 0.02). Groups were similar in preoperative characteristics. Depression/anxiety was more prevalent in NSO (12.4% vs. 3.4%, P = 0.03). Obstructive sleep apnea was higher in SO (21.3% vs. 10.1%, P = 0.04). Sleeve gastrectomy was performed most often (80.9%), with a tendency toward bypass in SO (P = 0.05). Early complication rates were: 13.5% in SO and 12.4% in NSO (P = 0.82). Mean follow-up was 80.4 ± 13.3 months. BMI reduction was higher in SO (31.8 ± 5.9 vs. 26.8 ± 4.2 kg/m2, P < 0.001) and time to nadir weight was longer (22.1 ± 21.3 vs. 13.0 ± 12.0 months, P = 0.001). Co-morbidity improvement and satisfaction were similar. CONCLUSIONS: Patients with SO benefited from bariatric surgery with reduced BMI and fewer co-morbidities. No added risk of operative complications was found compared to patients with NSO.

OBJECTIVES: To describe gastrointestinal-related side-effects reported following the One Anastomosis Gastric Bypass (OAGB). METHODS: A multicenter study among OAGB patients across Israel (n = 277) and Portugal (n = 111) who were recruited to the study based on time elapsed since surgery was performed. An online survey with information on demographics, anthropometrics, medical conditions, and gastrointestinal outcomes was administered in both countries simultaneously. RESULTS: Respondents from Israel (pre-surgery age of 41.6 ± 11.0 years, 75.8% females) and Portugal (pre-surgery age of 45.6 ± 12.3 years, 79.3% females) presented mean excess weight loss of 51.0 ± 19.9 and 62.4 ± 26.5%, 89.0 ± 22.0 and 86.2 ± 21.4%, and 89.9 ± 23.6 and 98.2 ± 20.9% (P < 0.001 for both countries), at 1-6 months, 6-12 months, and 1-5 years post-surgery, respectively. Median Gastrointestinal Symptom Rating Scale score was similar between time elapsed since surgery groups among respondents from Israel and Portugal (≤1.97 and ≤2.12). A notable proportion of respondents from Israel and Portugal at all time points reported 1-3 bowel movements per day (≤62.8 and ≤87.6%), Bristol stool scale categories which represent diarrhea-like stools (≤51.9 and ≤56.3%), having discomfort due to flatulence (≤79.4 and ≤90.2%), and mild to severe dyspepsia symptoms (≤50.5 and ≤73.0%). CONCLUSIONS: A notable proportion of OAGB patients might experience certain gastrointestinal symptoms postoperatively, including flatulence, dyspepsia, and diarrhea-like stools.

This study aimed to describe nutritional and lifestyle parameters following one-anastomosis gastric bypass (OAGB). A multicenter study among OAGB patients across Israel (n = 277) and Portugal (n = 111) was performed. Patients were approached according to the time elapsed since surgery. An online survey with information regarding demographics, anthropometrics, and nutritional and lifestyle aspects was administered in both countries simultaneously. Respondents from Israel (pre-surgery age of 41.6 ± 11.0 years, 75.8% females) and Portugal (pre-surgery age of 45.6 ± 12.3 years, 79.3% females) reported changes in their appetite (≤94.0% and ≤94.6%), changes in their taste (≤51.0 and ≤51.4%), and intolerance to specific foods (i.e., red meat, pasta, bread, and rice). Bariatric surgery-related eating recommendations were generally followed well, but a trend toward lower adherence was evident in groups with longer time elapsed since surgery in both countries. Most respondents from Israel and Portugal reported participation in follow-up meetings with a surgeon (≤94.0% and 100%) and a dietitian (≤92.6% and ≤100%), while far fewer reported participation in any follow-up meeting with a psychologist/social worker (≤37.9% and ≤56.1%). Patients following OAGB might experience changes in appetite, taste, and intolerance to specific foods. Adherence to bariatric surgery-related eating recommendations is not always satisfying, especially in the longer term post-surgery.

BACKGROUND: Reports of long-term (> 5-15-year) outcomes assessing the safety and efficacy of primary revisional laparoscopic sleeve gastrectomy (LSG) are few. METHODS: Retrospective long-term comparisons of primary (pLSG) and revisional (rLSG) procedures were matched for gender, age ± 5 years, and body mass index (BMI) ± 5 kg/m2. Weight loss, associated medical condition status, and patient satisfaction were evaluated. RESULTS: Between May 1, 2006, and December 31, 2016, 194 matched patients with severe obesity (mean BMI 44.1 ± 6.7 kg/m2; age 44.2 ± 10.0 years, 67.0% female) underwent pLSG (n = 97) or rLSG (n = 97) and were followed for a mean 12.1 ± 1.5 vs 7.6 ± 2.1 years. Respective mean weight regain from nadir was 15.0 ± 14.4 kg vs 11.9 ± 12.2 kg. Respective percent mean total weight loss and excess weight loss were 20.9 ± 12.7% and 51.8 ± 33.1%, and 18.3 ± 12.8% and 43.4 ± 31.6% at last follow-up, with no significant difference between groups. Resolution of type 2 diabetes (HbA1C < 6.5%, off medications) was 23.1% vs 11.1%; hypertension 36.0% vs 16.0%; and hyperlipidemia 37.1% vs 35.3%. Patients in the pLSG group were significantly more satisfied with LSG (59.8% vs 43.3%, p < 0.05) and more likely to choose the procedure again. CONCLUSIONS: There were no significant differences in long-term weight loss or associated medical condition outcomes in matched pLSG and rLSG patients.

BACKGROUND: Long-term laparoscopic sleeve gastrectomy (LSG) outcomes in patients with obesity are scarce. We aimed to examine the outcomes and subjective experience of patients who underwent primary LSG with long-term follow-up. METHODS: The study is a retrospective observational analysis of patients who underwent primary LSG in a single center with 5-15 years of follow-up. Patients' hospital chart data supplemented by a detailed follow-up online questionnaire and telephone interview were evaluated. RESULTS: The study sample included 578 patients (67.0% female) with 8.8 ± 2.5 years of mean follow-up, with a response rate to the survey of 82.8%. Mean baseline age and body mass index (BMI) were 41.9 ± 10.6 years and 42.5 ± 5.5 kg/m2, respectively. BMI at nadir was 27.5 ± 4.9 kg/m2, corresponding to a mean excess weight loss (EWL) of 86.9 ± 22.8%. Proportion of patients with weight regain, defined as nadir ≥ 50.0% EWL, but at follow-up < 50.0% EWL, was 34.6% (n = 200) and the mean weight regain from nadir was 13.3 ± 11.1 kg. BMI and EWL at follow-up were 32.6 ± 6.4 kg/m2 and 58.9 ± 30.1%, respectively. The main reasons for weight regain given by patients included "not following guidelines," "lack of exercise," "subjective impression of being able to ingest larger quantities of food in a meal," and "not meeting with the dietitian." Resolution of obesity-related conditions at follow-up was reported for hypertension (51.7%), dyslipidemia (58.1%) and type 2 diabetes (72.2%). The majority of patients (62.3%) reported satisfaction with LSG. CONCLUSIONS: In the long term, primary LSG was associated with satisfactory weight and health outcomes. However, weight regain was notable.

BACKGROUND: The European Association for Endoscopic Surgery Bariatric Guidelines Group identified a gap in bariatric surgery recommendations with a structured, contextualized consideration of multiple bariatric interventions. OBJECTIVE: To provide evidence-informed, transparent and trustworthy recommendations on the use of sleeve gastrectomy, Roux-en-Y gastric bypass, adjustable gastric banding, gastric plication, biliopancreatic diversion with duodenal switch, one anastomosis gastric bypass, and single anastomosis duodeno-ileal bypass with sleeve gastrectomy in patients with severe obesity and metabolic diseases. Only laparoscopic procedures in adults were considered. METHODS: A European interdisciplinary panel including general surgeons, obesity physicians, anesthetists, a psychologist and a patient representative informed outcome importance and minimal important differences. We conducted a systematic review and frequentist fixed and random-effects network meta-analysis of randomized-controlled trials (RCTs) using the graph theory approach for each outcome. We calculated the odds ratio or the (standardized) mean differences with 95% confidence intervals for binary and continuous outcomes, respectively. We assessed the certainty of evidence using the CINeMA and GRADE methodologies. We considered the risk/benefit outcomes within a GRADE evidence to decision framework to arrive at recommendations, which were validated through an anonymous Delphi process of the panel. RESULTS: We identified 43 records reporting on 24 RCTs. Most network information surrounded sleeve gastrectomy and Roux-en-Y gastric bypass. Under consideration of the certainty of the evidence and evidence to decision parameters, we suggest sleeve gastrectomy or laparoscopic Roux-en-Y gastric bypass over adjustable gastric banding, biliopancreatic diversion with duodenal switch and gastric plication for the management of severe obesity and associated metabolic diseases. One anastomosis gastric bypass and single anastomosis duodeno-ileal bypass with sleeve gastrectomy are suggested as alternatives, although evidence on benefits and harms, and specific selection criteria is limited compared to sleeve gastrectomy and Roux-en-Y gastric bypass. The guideline, with recommendations, evidence summaries and decision aids in user friendly formats can also be accessed in MAGICapp: https://app.magicapp.org/#/guideline/Lpv2kE CONCLUSIONS: This rapid guideline provides evidence-informed, pertinent recommendations on the use of bariatric and metabolic surgery for the management of severe obesity and metabolic diseases. The guideline replaces relevant recommendations published in the EAES Bariatric Guidelines 2020.

One anastomosis gastric bypass (OAGB) is an emerging bariatric procedure, yet data on its effect on the gastrointestinal tract are lacking. This study sought to evaluate the incidence of small-intestinal bacterial overgrowth (SIBO) following OAGB; explore its effect on nutritional, gastrointestinal, and weight outcomes; and assess post-OABG occurrence of pancreatic exocrine insufficiency (PEI) and altered gut microbiota composition. A prospective pilot cohort study of patients who underwent primary-OAGB surgery is here reported. The pre-surgical and 6-months-post-surgery measurements included anthropometrics, glucose breath-tests, biochemical tests, gastrointestinal symptoms, quality-of-life, dietary intake, and fecal sample collection. Thirty-two patients (50% females, 44.5 ± 12.3 years) participated in this study, and 29 attended the 6-month follow-up visit. The mean excess weight loss at 6 months post-OAGB was 67.8 ± 21.2%. The glucose breath-test was negative in all pre-surgery and positive in 37.0% at 6 months (p = 0.004). Positive glucose breath-test was associated with lower reported dietary intake and folate levels and higher vitamin A deficiency rates (p ≤ 0.036). Fecal elastase-1 test (FE1) was negative for all pre-surgery and positive in 26.1% at 6 months (p = 0.500). Both alpha and beta diversity decreased at 6 months post-surgery compared to pre-surgery (p ≤ 0.026). Relatively high incidences of SIBO and PEI were observed at 6 months post-OAGB, which may explain some gastrointestinal symptoms and nutritional deficiencies.

BACKGROUND: Bariatric patients have a high prevalence of hiatal hernia (HH). HH imposes various difficulties in performing laparoscopic bariatric surgery. Preoperative evaluation is generally inaccurate, establishing the need for better preoperative assessment. OBJECTIVE: To utilize machine learning ability to improve preoperative diagnosis of HH. METHODS: Machine learning (ML) prediction models were utilized to predict preoperative HH diagnosis using data from a prospectively maintained database of bariatric procedures performed in a high-volume bariatric surgical center between 2012 and 2015. We utilized three optional ML models to improve preoperative contrast swallow study (SS) prediction, automatic feature selection was performed using patients' features. The prediction efficacy of the models was compared to SS. RESULTS: During the study period, 2482 patients underwent bariatric surgery. All underwent preoperative SS, considered the baseline diagnostic modality, which identified 236 (9.5%) patients with presumed HH. Achieving 38.5% sensitivity and 92.9% specificity. ML models increased sensitivity up to 60.2%, creating three optional models utilizing data and patient selection process for this purpose. CONCLUSION: Implementing machine learning derived prediction models enabled an increase of up to 1.5 times of the baseline diagnostic sensitivity. By harnessing this ability, we can improve traditional medical diagnosis, increasing the sensitivity of preoperative diagnostic workout.

Non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) are prevalent liver conditions that underlie the development of life-threatening cirrhosis, liver failure and liver cancer. Chronic necro-inflammation is a critical factor in development of NASH, yet the cellular and molecular mechanisms of immune dysregulation in this disease are poorly understood. Here, using single-cell transcriptomic analysis, we comprehensively profiled the immune composition of the mouse liver during NASH. We identified a significant pathology-associated increase in hepatic conventional dendritic cells (cDCs) and further defined their source as NASH-induced boost in cycling of cDC progenitors in the bone marrow. Analysis of blood and liver from patients on the NAFLD/NASH spectrum showed that type 1 cDCs (cDC1) were more abundant and activated in disease. Sequencing of physically interacting cDC-T cell pairs from liver-draining lymph nodes revealed that cDCs in NASH promote inflammatory T cell reprogramming, previously associated with NASH worsening. Finally, depletion of cDC1 in XCR1DTA mice or using anti-XCL1-blocking antibody attenuated liver pathology in NASH mouse models. Overall, our study provides a comprehensive characterization of cDC biology in NASH and identifies XCR1+ cDC1 as an important driver of liver pathology.

BACKGROUND: Although diverting loop ileostomy (DLI) reversal is considered to be a relatively simple procedure, it is not immune from major morbidity. We aimed to compare outcomes of DLI reversal between elderly and non-elderly patients. METHODS: Retrospective review of all patients who underwent DLI reversal at a single tertiary medical centre between 2010 and 2020. The elderly group consisted of patients 70 or older compared to a control group of those younger than 70 years. RESULTS: During the study period, 307 patients underwent DLI reversal. Of these, 76 patients were in the elderly group (mean age 75.6) and 231 in the control group (mean age 55.3). The groups were comparable in terms of mean time interval between the creation of the ileostomy and reversal (242 versus 255 days, respectively, P = 0.5), choice between stapled and hand-sewn anastomoses (97.4% stapled anastomosis versus 93.1%, P = 0.086), median post-operative length of stay (5 days in both, P = 0.086), rates of post-operative complications (26.3% versus 26.8%, P = 0.99), severe complications (5.3% versus 6.9%, P = 0.81) and 30-day readmission rates (13.2% versus 10.8%, P = 0.58). Multivariate analysis found the time interval between the creation of the stoma and its reversal to be the only significant risk factor for major post-operative morbidity. Age was not found to be correlated with post-operative morbidity. CONCLUSION: The outcomes of loop ileostomy reversal in elderly patients are similar to non-elderly patients. Efforts should be made to decrease the time interval between the creation of the stoma and its reversal as this is a significant risk factor for major post-operative morbidity.

INTRODUCTION: Laparoscopic sleeve gastrectomy (LSG) is the most popular bariatric procedure performed worldwide. However, many patients undergo secondary surgery due to either weight-related and complication-related reasons or both. Conversional options vary with one-anastomosis gastric bypass (OAGB) and Roux-n-Y gastric bypass (RYGB) being the most common. The aim of the study was to assess the safety and efficacy of converting failed LSG to either OAGB or RYGB, and compare weight-related results and post-conversion complications. METHODS: Retrospective review of hospital records of patients who underwent conversion from LSG to either RYGB or OAGB due to insufficient weight loss or weight regain in 7 bariatric centers between 2013 and 2019. Data retrieved included demographics, anthropometrics, comorbidities, indication for conversion, conversion type, complications, and weight loss. RESULTS: During the study period, 396 patients were included in the study. Eighty-four (21%) patients were lost to follow-up. RYGB and OAGB were performed in 119 and 144 patients, respectively. Mean age and body mass index (BMI) at revision were 44.2 years (range 19-72) and 40.6 ± 5.9 kg/m2 (range 35-71), respectively. Of these, 191 (73%) were female. Percent total body weight loss (%TWL) was 16% ± 1% for the RYGB group vs. 23% ± 12% for the OAGB group (p = 0.0007) at a median follow-up of 29 months (range 7-78 months) following conversion. Gastroesophageal reflux disease (GERD) was significantly higher 1 year following conversion to OAGB vs. RYGB occurring in 25 (17.4%) and 9 (7.6%) patients, respectively (p = 0.018). CONCLUSIONS: Conversion of LSG to OAGB, compared to RYGB, results in increased weight loss but a higher rate of GERD and potential nutritional deficiencies.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is common in bariatric surgery candidates. We evaluated the effect of sleeve gastrectomy (SG) on NAFLD using validated non-invasive measures. METHODS: Patients with morbid obesity and NAFLD, planned for SG, were evaluated before and after surgery. Data collected included anthropometrics, biochemistry, adiponectin, SteatoTest™, NashTest™, FibroTest™, OWLiver® test and real-time ShearWave™ elastography (SWE). RESULTS: Twenty-six subjects were included in the study, mean age 44.1 ± 4.8 years, 69.2% males. One year following SG, body mass index decreased significantly from 41.7 ± 4.8 kg/m2 to 29.6 ± 4.5 kg/m2. Concomitantly, significant improvements in triglycerides, ALT, diabetes markers and adiponectin were observed. Mean steatosis, as measured by SteatoTest™, was significantly improved. Steatohepatitis score measured by NashTest™ and OWLiver® significantly decreased. Mean fibrosis, as measured by SWE liver stiffness and FibroTest™, did not change over time. CONCLUSION: Steatosis and steatohepatitis are significantly improved by SG as measured by non-invasive measures.

BACKGROUND: One anastomosis gastric bypass (OAGB) is gaining favor. Anastomotic perforation is a dreaded complication. OBJECTIVES: To describe a series of patients presenting with delayed (> 90 days) perforation of a marginal ulcer (MU) following OAGB. SETTING: Two university hospitals, Israel. METHODS: A retrospective query identifying patients after OAGB admitted with delayed MU perforation. Demographic characteristics, time between OAGB to presentation, clinical, laboratory and imaging at presentation and management data were collected. RESULTS: Between 1/2017-1/2020, 7 patients were identified. Mean body mass index (BMI) and time difference between OAGB and perforation were 14 kg/m2 (range 7-23) and 13 months (range 4-23), respectively. All presented with upper abdominal pain, 4 had concomitant nausea and vomiting. One patient displayed tachycardia, none had fever and 3 exhibited leukocyte abnormalities. C-reactive protein ranged widely (2-311 mg/L). Mean albumin level was 2.9 g/dL (range 1.9-4). Pneumoperitoneum was demonstrated in half of plain abdominal films and all computed tomography (CT) scans. Management was tailored to clinical status. Four patients underwent laparoscopic primary repair with omentopexy. Two patients were initially managed nonoperatively, one eventually requiring conversion to Roux-en-Y gastric bypass (RYGB) while the other recovered without further intervention. One patient underwent exploratory laparotomy and "damage control" management with pouch gastrostomy and double-barrel jejunostomy. Risk factors for MU were present in 4 cases. Mean length of hospital stay was 18 days (range 3-79 days). CONCLUSIONS: Perforation of MU may occur months to years after OAGB even without risk factors. Laboratory results are unreliable. The CT scan is diagnostic. A tailored approach can achieve good outcomes.

BACKGROUND: Surgery for obesity and metabolic diseases has been evolved in the light of new scientific evidence, long-term outcomes and accumulated experience. EAES has sponsored an update of previous guidelines on bariatric surgery. METHODS: A multidisciplinary group of bariatric surgeons, obesity physicians, nutritional experts, psychologists, anesthetists and a patient representative comprised the guideline development panel. Development and reporting conformed to GRADE guidelines and AGREE II standards. RESULTS: Systematic review of databases, record selection, data extraction and synthesis, evidence appraisal and evidence-to-decision frameworks were developed for 42 key questions in the domains Indication; Preoperative work-up; Perioperative management; Non-bypass, bypass and one-anastomosis procedures; Revisional surgery; Postoperative care; and Investigational procedures. A total of 36 recommendations and position statements were formed through a modified Delphi procedure. CONCLUSION: This document summarizes the latest evidence on bariatric surgery through state-of-the art guideline development, aiming to facilitate evidence-based clinical decisions.

BACKGROUND: The worldwide prevalence of obesity nearly tripled between 1975 and 2016. There are limited data quantifying national trends. The aim of this study is to evaluate and summarize current trends in bariatric surgery in Israel. METHODS: Data for all bariatric surgeries (BS) performed between January 2014 and December 2018 was collected from the Israel National Bariatric Surgery Registry (INBSR) and analyzed. RESULTS: During the study period, 42,296 BS were included in the INBSR. Females accounted for 68% and the mean age and body mass index were 41.6 ± 12.6 years and 42.0 ± 5.4 kg/m2, respectively. Most of the patients were Jewish, but there was a significant rise in number of Arabs undergoing BS during the study period. There was a gradual decline in the annual numbers of BS, except for a small rise in 2015. There was a significant rise in the rate of One Anastomosis-Mini Gastric Bypass (OAGB-MGB), from 0.1% in 2014 to 46.1% in 2018, making it the most prevalent BS in that year. Laparoscopic sleeve gastrectomy (SG) surgeries decreased steadily, from 80% in 2014 to 37% in 2018. The annual rate of Roux-en-Y gastric bypass (RYGB) remained essentially constant at 10%. The annual rates of gastric banding decreased sharply and the annual rates of duodenal switch, single anastomosis duodenal switch and biliopancreatic diversion were negligible. Bariatric surgery was distributed evenly between private (50.4%) and public (49.6%) hospitals. CONCLUSIONS: The numbers of BS are decreasing in Israel. There is a gradual but noticeable shift from SG to OAGB-MGB.

PURPOSE: To examine associations of patients' attendance to follow-up meetings with a registered dietitian (RD) and physical exercise practices with weight loss during the 1 year following laparoscopic sleeve gastrectomy (SG). METHODS: Of 241 patients with obesity who underwent SG during 2012, 184 (76.3%) participated in a 1-year follow-up telephone interview and had information on number of RD follow-up meetings. Clinical information was available from computerized patient files. Multiple logistic regression analysis, adjusting for propensity score, was computed to reveal factors associated with greater weight loss. RESULTS: The mean %TWL was 31.4 ± 6.1 and the mean number of reported RD meetings during the year following SG was 4.6. The proportion of physically active patients increased by 15% (from 23 to 42) among those who attended at least 3 RD follow-up meetings (n = 123), and by 5% (from 18 to 23) among those who attended fewer than 3 meetings (n = 61) (p = 0.05). Patients conducting physical exercise reported a lower level of pain/discomfort on the EQ5D quality-of-life questionnaire (p = 0.03). The adjusted regression model revealed no association between the number of RD follow-up meetings and weight-reduction success, but physical exercise during the year following SG conferred a 2.6 times greater odds of belonging to the upper two tertiles of the % excess body weight loss ( 95% CI 1.2-5.3). CONCLUSIONS: Patients with better adherence to RD follow-up meetings were also more physically active. Patients on physical exercise also achieved greater weight reduction following SG, and reported less pain or discomfort. Nutritional counselling and physical exercise are necessary to ensure maximal and sustainable benefits from SG. LEVEL OF EVIDENCE: Level III, Cohort study.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is a well-established bariatric procedure. A staple line leak is a recognized complication of LSG. Bougie size has been suggested to impact leak rates. In this study, we evaluate the impact of using 32-34F bougie sizes with LSG on early postoperative outcomes including staple line leaks within our practice. METHODS: This is a retrospective cohort analysis of a prospectively maintained database of all LSG procedures performed between January 2012 and December 2018 at a single medical center. Data collected and analyzed included bougie size, postoperative leak rate, need for re-operation, 12-month excess weight loss, and 30-day morbidity and mortality. RESULTS: During the study period, 3153 patients underwent LSG, of whom 1977 (62.7%) were female. Mean age and body mass index (BMI) were 42.9 ± 12.2 years (range 15-76 years) and 42.4 ± 5.2 kg/m2 (range 27-73), respectively. No intraoperative complications or mortality occurred. There was one case of perioperative mortality due to bleeding (0.03%). Early postoperative adverse events occurred in 131 patients (4.1%): 17 leaks (0.5%), 75 bleeds (2.4%), and 39 (1.2%) other. CONCLUSION: The use of smaller-sized (32-34F) bougies had no impact on staple line leaks in the hands of experienced bariatric surgeons at a high-volume center.

OBJECTIVE: Most published work on bariatric surgery (BS) in adolescents describes outcomes after laparoscopic adjustable gastric banding (LAGB) or Roux-en-Y gastric bypass. We compared the efficacy of LAGB and laparoscopic sleeve gastrectomy (LSG) in adolescents. METHODS: A National Bariatric Registry was queried for adolescents who underwent BS between June 2013 and December 2015. We collected data on weight and height at baseline and 1-year following surgery, subsequent hospitalizations, interventions, and mortality, which were compared at 30 days post-surgery and until last follow-up (maximum 4.2 years post-surgery). Mortality and hospitalization data were extracted from national databases. RESULTS: Two hundred fifty-nine adolescents (60% females) aged 12-19 years were included. Mean age and body mass index (BMI) were 17.5 ± 1.2 years and 45.1 ± 5.0 kg/m2, respectively. LSG (n = 227, 87.6%) and LAGB (n = 32, 12.4%) were the most common procedures performed. LSG group achieved greater average at 1 year BMI loss compared to LAGB group (15.4 ± 4.7 kg/m2 vs. 10.3 ± 5.1 kg/m2 respectively; p = 0.0001) and higher rate with BMI < 30 kg/m2 1 year post-surgery (57.7% (n = 131) vs. 25% (n = 8), respectively; p = 0.0005). Males who underwent LSG reduced BMI more than their female counterparts (p = 0.0001), LSG was the strongest independent predictor for BMI < 30 after 1 year (OR = 4.1; 95% CI 1.7-9.9) followed by age (OR = 1.3; 95% CI1.0-1.6). No mortality was observed. Postoperative hospitalizations between the two groups did not differ (hazard ratio 2.4; 95% CI 0.7-7.9; p = 0.1). CONCLUSION: Compared to LAGB, LSG is superior regarding weight loss with a similar risk of short- and long-term hospitalizations, complications, and interventional procedures. Males lose more weight following LSG.
