Abstract
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.

Abstract
BACKGROUND Long-term outcome data for bariatric surgery in patients with severe obesity (SO) (body mass index [BMI] 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 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.

Abstract
OBJECTIVES To describe gastrointestinal-related side-effects reported following 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.

Nutritional and Lifestyle Behaviors Reported Following One Anastomosis Gastric Bypass Based on a Multicenter Study. Nutrients 2023; 15:nu15061515. [PMID: 36986245 PMCID: PMC10053792 DOI: 10.3390/nu15061515] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2023] [Revised: 03/13/2023] [Accepted: 03/15/2023] [Indexed: 03/30/2023] Open
Abstract
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.

Abstract
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.

Abstract
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.

Abstract
BACKGROUND There are data on the safety of cancer surgery and the efficacy of preventive strategies on the prevention of postoperative symptomatic COVID-19 in these patients. But there is little such data for any elective surgery. The main objectives of this study were to examine the safety of bariatric surgery (BS) during the coronavirus disease 2019 (COVID-19) pandemic and to determine the efficacy of perioperative COVID-19 protective strategies on postoperative symptomatic COVID-19 rates. METHODS We conducted an international cohort study to determine all-cause and COVID-19-specific 30-day morbidity and mortality of BS performed between 01/05/2020 and 31/10/2020. RESULTS Four hundred ninety-nine surgeons from 185 centres in 42 countries provided data on 7704 patients. Elective primary BS (n = 7084) was associated with a 30-day morbidity of 6.76% (n = 479) and a 30-day mortality of 0.14% (n = 10). Emergency BS, revisional BS, insulin-treated type 2 diabetes, and untreated obstructive sleep apnoea were associated with increased complications on multivariable analysis. Forty-three patients developed symptomatic COVID-19 postoperatively, with a higher risk in non-whites. Preoperative self-isolation, preoperative testing for SARS-CoV-2, and surgery in institutions not concurrently treating COVID-19 patients did not reduce the incidence of postoperative COVID-19. Postoperative symptomatic COVID-19 was more likely if the surgery was performed during a COVID-19 peak in that country. CONCLUSIONS BS can be performed safely during the COVID-19 pandemic with appropriate perioperative protocols. There was no relationship between preoperative testing for COVID-19 and self-isolation with symptomatic postoperative COVID-19. The risk of postoperative COVID-19 risk was greater in non-whites or if BS was performed during a local peak.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

[PMID: 33268323 DOI: 10.1016/j.soard.2020.09.022] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Revised: 08/17/2020] [Accepted: 09/14/2020] [Indexed: 11/18/2022]
Abstract
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.

Associations of dietitian follow-up counselling visits and physical exercise with weight loss one year after sleeve gastrectomy. Eat Weight Disord 2020; 25:143-150. [PMID: 29987777 DOI: 10.1007/s40519-018-0531-0] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2018] [Accepted: 06/18/2018] [Indexed: 01/09/2023] Open
Abstract
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.

Abstract
BACKGROUND The endocannabinoid (eCB) system plays a key role in the development of obesity and its comorbidities. Limited information exists on the changes in circulating eCBs following bariatric surgery. OBJECTIVES This study aims to (i) assess the circulating levels of eCBs and related molecules and (ii) examine the association between their levels and numerous clinical/metabolic features pre- and post-operatively. METHODS Sixty-five morbidly obese patients (age 42.78 ± 9.27 years; BMI 42.00 ± 5.01 kg/m2) underwent laparoscopic sleeve gastrectomy (LSG) surgery, and were followed up for 12 months. Data collected included anthropometrics and metabolic parameters. The serum levels of the eCBs, 2-arachidonoylglycerol (2-AG), anandamide (AEA); and their related molecules, arachidonic acid (AA) and oleoylethanolamine (OEA) were measured by liquid chromatography-mass spectrometry. RESULTS Levels of 2-AG, AEA, and AA were reduced post operatively with no differences in serum OEA levels. The delta changes in eCB levels between pre- and post-operation were correlated with the delta of different metabolic parameters. Positive correlations were found between delta AA and waist circumference (WC) (r = 0.28, P < 0.05), free fat mass (r = 0.26, P < 0.05), SteatoTest score (r = 0.45, P < 0.05), and ALT (r = 0.32, P < 0.05). Delta AEA levels positively correlated with WC (r = 0.30, P < 0.05). Delta 2-AG levels positively correlated with total cholesterol (r = 0.27, P < 0.05), triglycerides (r = 0.55, P < 0.05), and SteatoTest score (r = 0.27, P < 0.05). Delta OEA levels negatively correlated with fasting glucose levels (r = - 0.27, P < 0.05). CONCLUSIONS This study provides compelling evidence that LSG surgery induces reductions in the circulating 2-AG, AEA, and AA levels, and that these changes are associated with clinical benefits related to the surgery including reduced fat mass, hepatic steatosis, glucose, and improved lipid profile.

Abstract
In the last decade, the number of bariatric surgery procedures increased dramatically in Israel similar to what has occurred worldwide. Bariatric surgery procedures have a proven efficacy in the treatment of morbid obesity. However, post-operative complications that involve the gastrointestinal tract may occur. Beyond the importance of early diagnosis and treatment, it is crucial to understand that we may decrease and prevent some of the complications by selecting the bariatric procedure according to the patient's medical background. This review addresses diagnosis, treatment and prevention of gastrointestinal diseases pre- and post-bariatric surgery procedures. Recommended pre-operative diagnostic procedures are listed including the eradication of helicobacter pylori and the protective effect of proton pump inhibitors. We reviewed the effect of specific bariatric procedures on gastroesophageal reflux disease and on intestinal motility. Prevention and treatment of nutritional deficits and metabolic complications are also discussed. Finally, this document was written by a panel of experts representing the attitudes of the Israeli Societies for Metabolic and Bariatric Surgery (ISMBS), Pharmaceutical (PSI), Study of Obesity and the Israeli Gastroenterology and Liver Diseases Association, all endorsed by the Institute for Quality in Medicine of the Israeli Medical Association (IMA).

Abstract
Although elective laparoscopic cholecystectomy is the accepted strategy after endoscopic retrograde cholangiopancreatography (ERCP), papillotomy, and common bile duct (CBD) clearance, the decision to perform a cholecystectomy in high-risk elderly comorbid patients remains subjective and is controversial. The aim of this study was to examine the outcome of elderly patients with cholecystectomy deferral after successful initial endoscopic removal of CBD stones. The study examined a retrospective patient database, which included all patients aged >60 years who underwent an ERCP for CBD stones at the Chaim Sheba Medical Center. The study cohort was divided according to whether a subsequent cholecystectomy was performed and also by age 60 to 80 or >80 years. All biliary-related complications were recorded. The primary outcome measures were biliary complications, perioperative and periprocedural mortality, CBD stone recurrence, and the need for future surgical intervention. There were 111 patients (mean age 79.4 ± 9.1 years) who underwent ERCP with follow-up. After excluding 11 patients, 100 patients were left for analysis, 46 of whom underwent a cholecystectomy and 54 were observed without operation. There were significant longer term biliary complications in five of the operated patients (10.9%) and in four of the unoperated cases (7.4%). All biliary-related complications were managed successfully by conservative means except for one fatality in the nonoperated group. Biliary-related complications after successful ERCP for CBD stones were unaffected by surgery but were more commonly observed in older cases. A watch and wait policy may be justified in elderly comorbid patients.

Abstract
INTRODUCTION Best practices for patient education in bariatric surgery (BS) remain undefined. The aims of this study were to evaluate the effect of an online lecture on nutrition knowledge, weight loss expectations, and anxiety among BS candidates and present a new tool to assess this knowledge before BS. METHODS An interventional non-randomized controlled trial on 200 BS candidates recruited while attending a pre-BS committee. The first 100 consecutive patients were assigned to the control group and the latter 100 consecutive patients to the intervention group and were instructed to watch an online lecture of 15-min 1-2 weeks prior to surgery. All participants completed a BS nutrition knowledge and the state-trait anxiety inventory (STAI) questionnaires at the pre-BS committee and once again at the pre-surgery clinic. Body mass index (BMI), comorbidities, surgery type, marital status, and number of dietitian sessions were obtained from medical records. RESULTS Data for paired study questionnaires scores were available for 128 patients (n = 69 and n = 59 for the control and intervention groups, respectively), with a mean age and BMI of 40.3 ± 11.4 years and 41.3 ± 4.9 kg/m2, respectively. The BS nutrition knowledge and the state anxiety scores increased for both study groups at the pre-surgery clinic as compared to the pre-BS committee (P ≤ 0.028), but the improvement in the nutrition knowledge score was significantly higher for the intervention group (P = 0.030). No within or between-group differences were found for the trait anxiety items score. The "dream" and "realistic" weight goals were lower than the expected weight loss according to 70% excess weight loss (EWL) for both study groups at both time-points (P < 0.001 for all). CONCLUSION Education by an online lecture prior to the surgery improves BS nutrition knowledge, but not anxiety. ClinicalTrials.gov number: NCT02857647.

Abstract
BACKGROUND AND AIMS Longitudinal assessment of body composition following bariatric surgery allows monitoring of health status. Our aim was to elucidate trends of anthropometric and clinical outcomes 3 years following sleeve gastrectomy (SG). METHODS A prospective cohort study of 60 patients who underwent SG. Anthropometrics including body composition analysis measured by multi-frequency bioelectrical impedance analysis, blood tests, liver fat content measured by abdominal ultrasound and habitual physical activity were evaluated at baseline and at 6 (M6), 12 (M12), and 36 (M36) months post-surgery. RESULTS Sixty patients (55% women, age 44.7 ± 8.7 years) who completed the entire follow-up were included. Fat mass (FM) was reduced significantly 1 year post-surgery (55.8 ± 11.3 to 26.7 ± 8.3 kg; P < 0.001) and then increased between 1 and 3 years post-operatively, but remained below baseline level (26.7 ± 8.3 to 33.1 ± 11.1 kg; P < 0.001). Fat free mass (FFM) decreased significantly during the first 6 months (64.7 ± 14.3 to 56.9 ± 11.8 kg; P < 0.001), slightly decreased between M6 and M12 and then reached a plateau through M36. Weight loss "failure" (< 50% excess weight loss) was noticed in 5.0% and 28.3% of patients at M12 and M36, respectively. Markers of lipid and glucose metabolism changed thereafter in parallel to the changes observed in FM, with the exception of HDL-C, which increased continuingly from M6 throughout the whole period analyzed (45.0 ± 10.2 to 59.5 ± 15.4 mg/dl; P < 0.001) and HbA1c which continued to decrease between M12 and M36 (5.5 ± 0.4 to 5.3 ± 0.4%; P < 0.001). There were marked within-person variations in trends of anthropometric and clinical parameters during the 3-year follow-up. CONCLUSIONS Weight regain primarily attributed to FM with no further decrease in FFM occurs between 1 and 3 years post-SG. FM increase at mid-term may underlie the recurrence of metabolic risk factors and can govern clinical interventions.

Abstract
BACKGROUND & AIMS One Anastomosis Gastric Bypass (OAGB) has been accepted as an effective treatment for morbid obesity. However, data are scarce regarding nutritional implications of this procedure. Thus, our aim was to describe the health and nutritional status 12-20 months following OAGB surgery. METHODS A prospective cohort study on patients who underwent OAGB surgery from January 2016 to May 2017 in a large, multi-disciplinary, bariatric clinic. Pre-surgery data including demographic details, anthropometrics, co-morbidities, blood tests and lifestyle habits were obtained from the patients' medical records. Follow-up evaluations were performed 12-20 months post-surgery and data collected included anthropometrics, blood tests, eating and lifestyle parameters, adherence to follow-up regime and gastrointestinal (GI) related side effects. In addition, patients were asked to rate their overall state of health (OSH) from 0 to 100 using a visual analogue scale (VAS). RESULTS Eighty-six OAGB patients (72.1% women) were tested 14.7 ± 2.0 months post-operatively. Their mean age and BMI preoperatively were 46.1 ± 11.4 years and 42.0 ± 4.9 kg/m2, respectively. The mean % excess weight loss at 12-20 months postoperatively was 88.4 ± 19.3%. Lipid and glucose profiles were significantly improved at 12-20 months postoperatively compared to baseline (P < 0.001 for all). Relatively high proportions of nutritional deficiencies were found pre-operatively and postoperatively for iron (33.9% vs. 23.7%, P = 0.238), folate (30.9% vs. 11.8%, P = 0.004), vitamin D (56.6% vs. 17.0%, P < 0.001) and hemoglobin (16.7% vs. 42.9%, P < 0.001). Postoperatively, most participants reported taking multivitamin, calcium, vitamin D and vitamin B12 supplementation (≥62.8%), having participated in at least 6 meetings with a dietitian (51.8%) and presently doing physical activity (69.4%). The mean postoperative OSH VAS score was 88.2 ± 12.3, but most participants reported on flatulence (67.4%) and some reported on diarrhea (25.6%) as GI side effects of the surgery. CONCLUSIONS Substantial improvements in health and anthropometric parameters are found in the short-term follow-up after OAGB, with a satisfactory reported quality of life and adherence to recommendations. However, a high prevalence of some GI side effects, nutritional deficiencies and specially anemia is a matter of concern.

Conversion for failed adjustable gastric banding warrants hiatal scrutiny for hiatal hernia. Surg Endosc 2018; 33:2231-2234.

Abstract
BACKGROUND Failure or complications following laparoscopic adjustable gastric banding (LAGB) may necessitate band removal and conversional surgery. Band position and band-induced chronic vomiting create ideal conditions for de novo hiatal hernia (HH) formation. HH presence impedes and complicates conversional surgery by obscuring crucial anatomical landmarks and hindering precise gastric sleeve or pouch formation. The aim of this study was to evaluate the incidence of a HH in patients with an LAGB undergoing conversion compared to patients undergoing primary bariatric surgery (BS). METHODS Retrospective review of consecutive BS performed between 2010 and 2015. Data collected included demographics, anthropometrics, comorbidities, previous BS, preoperative and intra-operative HH detection, operation time, perioperative complications and length of hospital stay. RESULTS During the study period, 2843 patients (36% males) underwent BS. Of these, 2615 patients (92%) were "primary" (no previous BS-control group), 197 (7%) had a previous LAGB (study group), and 31 (1%) had a different previous BS and were excluded. Reasons for conversion included weight regain, band intolerance and band-related complications. Mean age and body mass index were similar between the study and the control groups. HH was preoperatively diagnosed by upper gastrointestinal (UGI) fluoroscopy in 9.1% and 9.0% of the LAGB and control groups (p = NS), respectively. However, HH was detected intra-operatively in 20.3% and 7.3%, respectively (p < 0.0001). CONCLUSIONS Preoperative diagnosis of a HH by UGI fluoroscopy for patients who have undergone LAGB is unreliable. Intra-operative hiatal exploration is highly recommended in all cases of conversional BS after LAGB.

Abstract
AIMS Transoesophageal echocardiography (TEE) and multidetector computed tomography (MDCT) currently serve as imaging modalities for left atrial appendage (LAA) occlusion preprocedural planning. We assessed the feasibility of MDCT-based models to predict the correct size of device for LAA occlusion procedures. METHODS AND RESULTS Patients planned for LAA occlusion underwent MDCT before implantation, which was used for creating and printing 3D LAA models. Three cardiologists evaluated the 3D models and predicted the correct size of the device by manual manipulation. These predictions were compared with the actual device implanted during the procedure. Twenty-nine patients were included in this study. AMPLATZER and WATCHMAN devices were deployed in 12 and 17 patients, respectively. Two procedures were aborted due to failure of occlusion; all three physicians predicted it. There was good correlation between the 3D models and the inserted device for AMPLATZER devices with a concordance correlation coefficient of 0.778 (p=0.001) and poor agreement for WATCHMAN devices - concordance correlation coefficient of 0.315 (p=0.203). Agreement among the three physicians for AMPLATZER and WATCHMAN devices was excellent, with a calculated average intra-class correlation of 0.915 and 0.816, respectively. CONCLUSIONS We found LAA printed 3D models to be accurate for prediction of LAA occluder device size for the AMPLATZER device but not for the WATCHMAN device.

Abstract
INTRODUCTION Various definitions for bariatric surgery (BS) success exist, with weight loss and comorbidity resolution outcomes being the most prominent. The study's aim was to compare how various healthcare professionals perceive success in BS. METHODS A 29-item, 10-point Likert scale online survey was distributed via email to Israeli healthcare professionals involved in the different BS aspects using common national professional organizations. These included bariatric surgeons, dietitians, social workers, psychologists, psychiatrists, primary care physicians, gastroenterologists, and nurses. Statement relevancy to BS success was rated. An item was classed as "very important" for BS success if at least 70% of participants rated it 8 or higher in each subgroup. Inter-observer agreement was calculated using kappa statistics. Data on specific occupation, years-in-practice, and major workplace were collected as well. RESULTS A total of 155 responses was obtained. The majority of respondents were dietitians (34.8%, n = 54), followed by bariatric surgeons (31.0%, n = 48) and nurses (14.8%, n = 23). Most respondents work mainly at public hospitals (32.9%, n = 51), followed by private hospitals (26.5%, n = 41). The mean years-in-practice among all healthcare professionals was 8.5 ± 8.5 years. Overall inter-observer agreement for prioritized items in accordance to BS success among all health professional subgroups was fair (Fleiss kappa = 0.278, P < 0.001), while dietitians and mental health specialists showed the highest agreement rate (Cohen's kappa = 0.592, P < 0.001). CONCLUSION The study highlights the various views on defining BS success by different healthcare professionals, although there was some overlap of core outcomes prioritized by all professionals. International uniform definitions for BS success are required.

Abstract
BACKGROUND Data on adherence to postoperative lifestyle recommendations by bariatric patients are scarce. Thus, the aim of this study was to evaluate adherence to selected recommendations during the first year following laparoscopic sleeve gastrectomy (LSG) surgery. METHODS A prospective cohort study with 12 months of follow-up on 100 LSG patients was conducted. Data were collected at baseline and at 3 (M3), 6 (M6), and 12 (M12) months post-surgery and included anthropometrics, biochemical tests, food intake, food tolerance, common surgery-related side effects, physical activity (PA), supplementation, and number of follow-up meetings with a dietitian. RESULTS Data were available for 77 patients (57.1% women, mean age 43.1 ± 9.3 years and preoperative BMI 42.1 ± 4.8 kg/m2). Only a minority of the patients adhered to the recommended protein intake ≥60 g/day at all time points (≤40.3%) and ≥6 meetings with a dietitian at M12 (41.6%). Half of the patients performed ≥150 min/week of PA at all time points (≤50.6%) as recommended. PA of ≥150 min/week was associated with better lipid and glucose changes at M6 and M12 (P ≤ 0.044). Most of the patients adhered to the recommended supplementation at all time points (≥57.1%). Adherence to supplementation at M12 was significantly associated with higher serum levels of folic acid, iron, hemoglobin, and vitamins D and B12 (P ≤ 0.056 for all). Adherence to all recommendations was not significantly associated with excess weight loss ≥60% at M12 (P ≥ 0.195 for all). CONCLUSION Bariatric patients have medium to high adherence to the major lifestyle recommendations during the first year following LSG; however, adherence to those recommendations was not related to better weight loss at short-term follow-up. Adherence to recommended supplementation was associated with better micronutrient status 1 year postoperatively.

Abstract
BACKGROUND Single anastomosis gastric bypass (SAGB) has been established as a safe and effective bariatric procedure. SAGB has also been suggested as a conversion option from other procedures, but so far not extensively explored in that direction. METHODS The study retrospectively reviewed and analyzed 154 consecutive SAGB procedures, including 48 conversional SAGB (cSAGB) and 106 primary SAGB (pSAGB). Preoperative physical dimensions and perioperative complications were obtained. Patients were followed 1, 3, and 6 months postoperatively, with weight measurements compared between groups. RESULTS Operative times were longer in the cSAGB group but length of hospital stay was the same for both groups. Sixty-five percent of the cSAGB group had adjustable banding as a primary operation, and 94 % opted for conversion due to insufficient weight loss or regain thereof. Follow-up data availability was 98, 82, and 79 % for the three checkpoints. Three and 6 months postoperatively, cSAGB had inferior mean excess weight loss (EWL) compared to pSAGB, though both groups were successful after 6 months (mean EWL >50 %). Body mass index loss was significantly higher for pSAGB for the first postoperative 3 months. Low complication rates in both groups precluded statistical comparison in that respect. DISCUSSION Initial weight loss after conversional SAGB is inferior to primary SAGB after 6 months. The observed safety of cSAGB is comparable to previous evidence for this procedure in the conversional settings. CONCLUSION SAGB may be considered as a safe and effective conversional procedure, but not as effective as pSAGB for initial weight loss.

The Intact ® breast lesion excision system as a therapeutic device for selected benign breast lesions. Breast J 2017; 24:304-308. [PMID: 29024205 DOI: 10.1111/tbj.12931] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2016] [Revised: 01/18/2017] [Accepted: 02/16/2017] [Indexed: 11/28/2022]
Abstract
The aim of this paper is to evaluate our Unit's initial experience using the Intact breast lesion excision system as a therapeutic excision option for benign or borderline breast lesions, which otherwise would entail open operative excision. The study includes the first 111 patients who underwent therapeutic excision with the intact radiofrequency system between December 2012 and May 2016 performed at the Meirav Center for Breast Health, at the Chaim Sheba Medical Center, Ramat Gan Israel. The indications for the procedure included those patients who have benign, or atypical high risk lesions following a previous core needle biospy (CNB) who would have normally undergone conventional excision biopsy. After reviewing each case separately, we found that the use of the BLES system as a treatment device permitted the avoidance of operations that would have been otherwise indicated, in 98 cases of the total 111 in the cohort (88.3%). Thirteen cases eventually had to undergo surgical excision. In eight cases pathology was upgraded from the initial CNB to invasive or noninvasive carcinoma. Although the INTACT sysytem is most commonly used as an alternative biopsy technique for its diagnostic capabilities, this study assessed its clinical role as a definitive therapeutic excisional modality in selected cases of benign breast disease. It proved valuable in the majority of cases with avoidance of surgery where it was traditionally indicated, (98/111, 88.3%) and as definitive fibroadenoma management in a further 28 patients.

Abstract
BACKGROUND Bariatric surgery (BS) is effective in treating obesity and its associated comorbidities. However, there is a paucity of data on the effect of BS on thyroid function in hypothyroid patients, specifically in those treated with thyroid hormone replacement therapy (THR). The aim of this study was to assess the effect of BS on thyroid function and on THR dosage in patients with hypothyroidism. METHODS A retrospective analysis of prospectively collected data of all hypothyroid patients who underwent BS between 2010 and 2014 was performed. Data collected included demographic and anthropometric measurements, as well as changes in thyroid hormone levels and THR dosage up to a year from surgery. RESULTS During the study period, 93 hypothyroid patients (85 females, 91%), 83 of which treated with replacement thyroid hormone, underwent BS. Laparoscopic sleeve gastrectomy was performed in 77 (82.8%) and Roux-en-Y gastric bypass in 16 patients. Average age and body mass index (BMI) were 46.6 ± 11.2 years and 43.7 ± 6.4 kg/m2, respectively. Mean BMI and thyroid-stimulating hormone (TSH) significantly deceased after 6 and 12 months following surgery whereas mean free T4 levels remained stable. TSH decrease was directly correlated to baseline TSH but not to BMI reduction. One year after surgery, 11 patients (13.2%) did not require THR, while the rest required a significantly lower average dose (P < 0.02). CONCLUSIONS There is a favorable effect of BS on the hypothyroid bariatric population. This includes improvement of thyroid function and reduction of thyroid medication dosages. Further studies are required to evaluate an influence of THR absorption and compare different types of bariatric surgeries.

Abstract
BACKGROUND AND OBJECTIVES Stage III malignant melanoma is a heterogeneous disease where those cases deemed marginally resectable or irresecatble are frequently incurable by surgery alone. Targeted therapy takes advantage of the high incidence of BRAF mutations in melanomas, most notably the V600E mutation. These agents have rarely been used in a neoadjuvant setting prior to surgery. METHODS Thirteen consecutive patients with confirmed BRAFV600E regionally advanced melanoma deemed marginally resectable or irrresectable, were treated with BRAF inhibiting agents, prior to undergoing surgery. The primary outcome measures were a successful resection and pathological response. Disease-free survival was a secondary outcome measure. RESULTS Overall, 12/13 patients showed a marked clinical responsiveness to medical treatment, enabling a macroscopically successful resection in all cases. Four patients had a complete pathological response with no viable tumor evident in the resected specimens and eight patients showed evidence of minimally residual tumor with extensive tumoral necrosis and fibrosis. One patient progressed and died before surgery. At a median follow up of 20 months, 10 patients remain free of disease. CONCLUSIONS Perioperative treatment with BRAF inhibiting agents in BRAFV600E mutated Stage III melanoma patients facilitates surgical resection and affords satisfactory disease free survival.

Abstract
INTRODUCTION The European Association of Endoscopic Surgeons (EAES) conducted this study aiming to identify the top research questions which are relevant to surgeons in Minimal Access Surgery (MAS). This is in order to promote and link research questions to the current clinical practice in MAS in Europe. METHODS Using a systematic methodology, (modified Delphi), the EAES members and leadership teams were surveyed to obtain consensus on the top research priorities in MAS. The responses were categorized and redistributed to the membership to rate the level of importance of each research question. The data were reported as the weighted average score with a scale from 1 (lowest agreement) to 5 (highest agreement). RESULTS In total, 324 of 2580 (12.5%) of the EAES members and the leaders responded to the survey and contributed to the final consensus. The ranked responses over the 80th percentile identified 39 research priorities with rating ranged from 4.22 to 3.67. The top five highest ranking research priorities in the EAES were centered on improving training in MAS, laparoscopic surgery for benign upper gastrointestinal conditions, integration of novel technology in OR, translational and basic science research in bariatric surgery and investigating the role of MAS in rectal cancer. CONCLUSION An EAES research agenda was developed using a systematic methodology and can be used to focus MAS research. This study was commissioned by the European Association for Endoscopic Surgery (EAES).

Abstract
AIM To investigate the role of cardiac CT angiography (CCTA) in predicting optimal left atrial appendage (LAA) occluder size and procedure outcome. METHODS AND RESULTS Thirty-six patients underwent pre-procedural CCTA. CCTA and TEE LAA orifice diameters and perimeters were compared with the implanted device size. CCTA 3D configuration was correlated with procedure outcome. Watchman™ device (N = 18): diameters were 21 ± 4, 26 ± 5 and 25 ± 3 mm for TEE, CCTA and inserted device, respectively. Average perimeters were 61 ± 10, 74 ± 8 and 78 ± 11 mm for TEE, CCTA and inserted device, respectively. Better agreement with the device size was found for CCTA compared to TEE (Bland-Altman). ACP™ device (N = 15): diameters were 20 ± 5, 25 ± 4 and 23 ± 4 for TEE, CCTA and inserted device, respectively. Average perimeters were 58 ± 11, 72 ± 15 and 72 ± 13 mm for TEE, CCTA and inserted device, respectively. Excellent correlation and agreement with the device size was found for CCTA compared to TEE. CCTA perimeter >100 mm and "cactus" 3D configuration had a specificity of 96 and 81% respectively for procedure failure. CONCLUSIONS CCTA LAA ostial perimeter predicted better the optimal occluder size as compared with the currently used LAA TEE diameter. Moreover, CCTA 3D data may help in predicting potential complications.

Abstract
BACKGROUND Although laparoscopic sleeve gastrectomy (LSG) has been shown to have a long-term antidiabetic effect, little is known regarding the immediate response to surgery. This study's objective was to evaluate the glycemic and lipid metabolic response in the first postoperative week. METHODS The study included 21 obese diabetic participants. Glycemic markers, lipids, and hepatic function tests were measured just prior to surgery and at 1 week and 3 months postoperatively. Two participants were dropped prior to all measurements due to technical reasons, and two more were lost to follow-up. RESULTS At 1 week after surgery, compared to preoperative baseline, we found reduced hemoglobin A1c (7.63 to 7.31, P < 0.001), insulin (24.96 to 10.92, P < 0.05), and borderline significant homeostatic model assessment insulin resistance (HOMA-IR, 9.48 to 3.91, P > 0.05). Low-density lipoprotein (LDL) cholesterol increased and high-density lipoprotein (HDL) cholesterol decreased. Three months after surgery, hemoglobin A1c, insulin, and HOMA-IR continued to decrease (6.05, 7.11, and 1.92, respectively, P < 0.05), with hemoglobin A1c correlated to weight loss (P < 0.05). Triglycerides, triglyceride to HDL ratio, and total cholesterol to HDL ratio also decreased, but there was no significant change in LDL cholesterol or HDL versus presurgery levels. Reduced triglyceride levels were correlated with reduced alanine transaminase (ALT) and gamma-glutamyl transpeptidase (GGT) (P < 0.05). CONCLUSIONS LSG is associated with marked antidiabetic effects as early as 1 week after surgery, unrelated to weight loss. The antidiabetic effect improves at 3 months. Triglyceride reduction was associated with improved hepatic functions, but cholesterol did not show a meaningful reduction.

Abstract
BACKGROUND Gallbladder (GB) cancer is rare. Most cases are incidentally found in specimens after a cholecystectomy. Cholelithiasis is almost always present when this diagnosis is made. Obesity is a known risk factor for gallstone formation and thus may be related to GB cancer. OBJECTIVES To highlight the importance of evaluating the gallbladder before surgery, resecting the gallbladder whenever required, and screening the resected tissue for malignancy. METHODS We retrospectively searched a prospectively maintained database of all bariatric procedures during the last 8 years for cases of concomitant laparoscopic sleeve gastrectomy (LSG) and laparoscopic cholecystectomy (LC). Pathologic reports of the gallbladders were reviewed. Demographic data and perioperative parameters were documented. RESULTS Of 2708 patients reviewed, 1721 (63.55%) were females and 987 (36.45%) males. Excluded were 145 (5.35%) who had a previous cholecystectomy. Of the remaining 2563, 180 (7.02%) had symptomatic gallbladder disease and underwent LSG with LC. Of these, two females (BMI 53 kg/m2 and 47 kg/m2, both age 60) were found by histological examination to have adenocarcinoma in their GB specimens (1.11%). Both were reoperated, which included partial hepatectomy of the GB bed, resection of the cystic stump, lymph node dissection, and resection of the port sites. One patient is doing well, with no evidence of disease at a postoperative follow-up of 4 years. The second patient had recurrent disease with peritoneal spread and ascites 20 months post-surgery and died 18 months later. CONCLUSIONS GB cancer is a rare finding in cholecystectomy specimens. The incidence of this entity might be higher in obese older females owing to the higher incidence of cholelithiasis in these patients.

Abstract
BACKGROUND Obesity causes specific sexual problems, including diminished sexual desire, poor performance and avoidance of sexual encounters. OBJECTIVES To systematically evaluate the effect of bariatric surgery on patients' sexual function as compared to their preoperative status. METHODS Bariatric surgery candidates were given a validated sexual function questionnaire the day before surgery and again 6 months after surgery. Females were polled with the Female Sexual Function Index (FSFI) and males with the Brief Sexual Function Inventory (BSFI). Statistical analysis was performed to elucidate differences in response to the questionnaires. RESULTS The study population included 34 females and 14 males. Mean age and body mass index (BMI) were 40.2 ± 10.2 years and 43.4 ± 5.3 kg/m2, respectively. Postoperative BMI was 31.4 ± 4.9 kg/m2 (P < 0.001). Laparoscopic sleeve gastrectomy was performed in 36 patients and laparoscopic Roux-Y gastric bypass in 12. In females, the FSFI index rose significantly from 24 to 30 (P = 0.006), indicating increased sexual performance and satisfaction. In males the BSFI increased from 40.2 to 43.9 but did not reach statistical significance (P = 0.08). However, general satisfaction, desire and erection were each significantly improved within the BSFI. CONCLUSIONS In addition to the well-documented medical and quality-of-life benefits of bariatric surgery, there is also clear improvement in patients' sexual function, both physical and psychosexual.

Abstract
BACKGROUND Laparoscopic Roux-Y gastric bypass (LRYGBP) is the gold-standard procedure for the treatment of morbid obesity. It has been reported to be somewhat more efficient and durable than laparoscopic sleeve gastrectomy (LSG). However, it is considered more invasive and, therefore, more hazardous. There is a lack of unity in complication reporting following bariatric surgery. Thus, there is a possible misconception regarding the relative safety of the two major bariatric procedures performed worldwide. This may have contributed to a shift in practice with LSG gaining momentum "at the expense" of LRYGBP. The aim of this study was to evaluate the relative safety of primary LSG and LRYGBP according to the Clavien-Dindo complication grading system. METHODS A total of 2651 and 554 patients underwent primary LSG and LRYGBP, respectively at three high-volume centers. Thirty-day perioperative complications were recorded and graded. Length of hospital stays (LOS) and readmission rates were collected as well. RESULTS Complications occurred in 110 (3.7%) and 24 (4.3%) patients following LSG and LRYGBP, respectively (p = 0.9). No significant difference was found between the groups regarding overall and complication-grade-specific rates. Individual complication types were unevenly distributed, but not significantly so. Patients with complications were older than those without (47 and 43 years, respectively; p = 0.01). Gender was not a risk factor for complication. Median LOS and readmission rates were not significantly different. CONCLUSIONS LSG and LRYGBP are equally safe, at least in the perioperative period. Acknowledging and conveying this finding to surgeons and patients alike is important and might cause a pendulum shift in the distribution of bariatric procedures performed.

Abstract
The obesity epidemic has been recognized as a worldwide problem. More than 1/3 of the adults and about 15% of children and adolescents are overweight. In the search for the reasons for obesity and refractory obesity, some research efforts have recently been directed into the relationship between obesity and attention deficit hyperactivity disorder (ADHD). This link can be explained by two theoretical approaches: ADHD leads to obesity because of the impulsive behavior of ADHD patients; both obesity and ADHD originate from a similar psycho-pathological mechanism. ADHD is usually diagnosed in childhood with symptoms of hyperactivity, impulsivity, and distraction, often continuing into adulthood with symptoms of disorganization, frustration, and excessive emotional reaction. Treatment of ADHD requires a multidisciplinary approach of medication, psychological treatment, occupational therapy (in children) and nutritional assistance. Most studies of the association between ADHD and obesity were performed on subjects seeking help for obesity problems. In this population (both children and adults), the percentage of ADHD was found to be significantly higher than the prevalence of ADHD in the general population. Overweight subjects with ADHD, who were treated with medications, showed improved patterns of weight loss and maintenance. In addition, patients diagnosed with ADHD had lower compliance with follow-up visits after bariatric surgery. It seems that the problem is in the correct diagnosis of ADHD in obese patients, followed by medical as well as cognitive behavioral treatment, that can turn the impulsivity into an advantage, driving patients to positive pathways such as physical activity.

Abstract
OBJECTIVES Elastography assesses the strain of soft tissues and is used to enhance diagnostic accuracy in evaluating breast tumors, but minimal data exist on its ability to accurately assess tumor size. This study was performed to assess the preoperative accuracy of measuring the size of biopsyproven breast cancer lesions with elastography and conventional B-mode sonography compared with the reference standard size measured by histopathologic examination. METHODS Elastography and conventional B-mode sonography were performed on 69 women with histologically proven breast cancer, and tumor sizes on both modalities were recorded. These measurements were compared with the final pathologic size, which was used as the reference standard. The sizes and differences between sonographic, elastographic, and pathologic measurements were statistically tested, and an analysis of equivalence to the reference standard was performed using Bland-Altman plots. RESULTS There was a significant difference between sizes on elastography and pathologic examination, with elastography overestimating the tumor size (P = .0187). Sonography slightly underestimated the tumor size, but this finding was not significant (P = .36). Bland-Altman plots confirmed that sonography but not elastography was an acceptable standard compared with the pathologic size. CONCLUSIONS Breast elastography but not B-mode sonography overestimates the size of breast tumors compared with the final pathologic size.

Abstract
BACKGROUND Modifications to conventional laparoscopic cholecystectomy (CLC) are aimed at decreasing abdominal wall trauma and improving cosmetic outcome. Although single-incision laparoscopic surgery (SILS) provides excellent cosmetic results, the procedure is technically challenging and expensive compared to the conventional laparoscopic approach. OBJECTIVES To describe a novel, hybrid technique combining SILS and conventional laparoscopy using minimal abdominal wall incisions. METHODS Fifty patients diagnosed with symptomatic cholelithiasis were operated using two reusable 5 mm trocars inserted through a single 15 mm umbilical incision and a single 2-3 mm epigastric port. This technique was clubbed "minimal incision laparoscopic cholecystectomy" (MILC). RESULTS MILC was completed in 49 patients (98%). In five patients an additional 3 mm trocar was used and in 2 patients the epigastric trocar was switched to a 5 mmtrocar. The procedure was converted to CLC in one patient. Mean operative time was 29 minutes (range 18-60) and the average postoperative hospital stay was 22 hours (range 6-50). There were no postoperative complications and the cosmetic results were rated excellent by the patients. CONCLUSIONS MILC is an intuitive, easy-to-learn and reproducible technique and requires small changes from CLC. As such, MILC may be an attractive alternative, avoiding the cost and complexity drawbacks associated with SILS.

Abstract
BACKGROUND Crohn's disease (CD) is frequently associated with weight loss and malnutrition. However, as the prevalence of obesity increases worldwide, it may become a clinical problem even in CD. AIM To assess the prevalence of severe/morbid obesity in CD patients and to compare their disease characteristics to nonobese CD patients. METHODS A retrospective analysis of a computerized CD patient database was performed to identify severely/morbidly obese patients (BMI >35). Prevalence was compared to data of the general population. Severely/morbidly obese CD patients were then compared to randomly selected nonobese CD patients (BMI <30) in a 1:3 ratio. RESULTS Thirteen severely/morbidly obese patients out of 560 CD patients were found (2.3%), which is significantly lower than the prevalence in the general population (5.6%, p = 0.001). When compared to 39 nonobese CD patients, colonic disease was significantly more common among severely/morbidly obese CD patients (odds ratio: 6, 95% CI: 1.35-26.3, p = 0.02), while there was no difference in other disease parameters. Interestingly, 4 morbidly obese CD patients had undergone laparoscopic sleeve gastrectomy for treatment of morbid obesity with a favorable surgical course. CONCLUSION CD in severely/morbidly obese patients is more often colonic, but otherwise no different than CD in nonobese patients. Sleeve gastrectomy is a viable therapeutic option for morbidly obese CD patients.
