Abstract
PURPOSE OF REVIEW The purpose of this review is to summarize the therapeutic approach for lipodystrophy syndromes with conventional treatment options and metreleptin therapy in detail and to point out the current investigational treatments in development. RECENT FINDINGS The observation of leptin deficiency in patients with lipodystrophy and the potential of leptin replacement to rescue metabolic abnormalities in animal models of lipodystrophy were followed by the first clinical study of leptin therapy in patients with severe lipodystrophy. This and several other long-term studies demonstrated important benefits of recombinant human leptin (metreleptin) to treat metabolic abnormalities of lipodystrophy. These studies ultimately led to the recent FDA approval of metreleptin for the treatment of generalized lipodystrophy and EMA approval for both generalized and partial lipodystrophy. Additional research efforts in progress focus on novel treatment options, predominantly for patients with partial lipodystrophy. Current treatment of generalized lipodystrophy includes metreleptin replacement as an adjunct to diet and standard treatment approach for metabolic consequences of lipodystrophy. Beyond metreleptin, a number of different compounds and treatment modalities are being studied for the treatment of partial lipodystrophy.

Abstract
Objective We investigated whether vertical sleeve gastrectomy (VSG) and Roux-en-Y gastric bypass surgery (RYGB) have a differential impact on post-operative risk of acute pancreatitis (AP). Methods This retrospective study uses the 2012–2014 National Readmission Database. We compared morbidly obese patients who underwent VSG (n = 205,251), RYGB (n = 169,973), and hernia repair (HR) control (n = 16,845). Our main outcome was rates of AP within 6 months post- vs. 6 months pre-surgery in VSG, RYGB, and HR. We also investigated risk factors and outcomes of AP after bariatric surgery. Results The rates of AP increased post- vs. pre-VSG (0.21% vs. 0.04%; adjusted odds ratio [aOR] = 5.16, P < 0.05) and RYGB (0.17% vs. 0.07%; aOR = 2.26, P < 0.05) but not post-HR. VSG was associated with a significantly greater increase in AP risk compared to RYGB (aOR = 2.28; 95% CI: 1.10, 4.73). Furthermore, when compared to HR controls, only VSG was associated with a higher AP risk (aOR = 7.58; 95% CI: 2.09, 27.58). Developing AP within 6 months following bariatric surgery was mainly associated with younger age (18–29 years old: aOR = 3.76 for VSG and aOR: 6.40 for RYGB, P < 0.05) and gallstones (aOR = 85.1 for VSG and aOR = 46 for RYGB, P < 0.05). No patients developed “severe AP” following bariatric surgery. Conclusions More patients develop AP within 6 months after VSG compared to RYGB and controls. This risk is highest for younger patients and those with gallstones. Prospective studies examining mechanisms and prevention are warranted.

Abstract
BACKGROUND The use of robotic platforms in performing laparoscopic Roux-en-Y gastric bypass (LRYGB) is increasing, though their safety compared with the conventional laparoscopic approach remains unclear. OBJECTIVE The objective of this study was to evaluate perioperative data and 30-day outcomes of conventional and robot-assisted LRYGB using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program data registry. SETTING University health network, United States. METHODS We reviewed all conventional and robot-assisted LRYGB cases entered between January 1 and December 31, 2016 in the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program data registry. Demographic characteristics and 30-day outcomes were analyzed based on separate Mann-Whitney rank sums tests, χ2, or Fisher's exact tests as appropriate, with P ≤ .05 denoting statistical significance with no adjustment for multiple testing. RESULTS Of the 39,425 patients who underwent LRYGB, 2822 were robot-assisted. The robot-assisted approach required significantly more time (138 versus 108 min, P < .0001). Rates of organ space infection, bleeding, and other significant adverse events after the conventional and robot-assisted approaches were .3% versus .5% (P = .13), 1.1% versus .8% (P = .11), and 2.3% versus 2.3% (P = .96), respectively. There were also no significant differences in the rates of mortality, length of stay, reoperation, or readmission between the 2 groups. CONCLUSIONS Robot-assisted LRYGB is an increasingly popular alternative to the conventional laparoscopic approach. According to the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database, the early safety of these 2 techniques is equal, although the robotic approach requires more operative time.

Abstract
BACKGROUND Patients with a body mass index (BMI) >35 kg/m2 who need kidney transplant present with increased postoperative mortality and reduced kidney graft survival compared to patients with a lower BMI. For this reason, obese patients are often excluded from the transplantation waiting list. The aim of this study was to evaluate the feasibility and the results of laparoscopic sleeve gastrectomy (LSG) for obese patients awaiting a kidney transplant. METHODS This was a retrospective study on patients with dialysis-dependent renal failure (DDRF) operated on at two first-level bariatric centers in Paris (France). All the patients were contraindicated for kidney transplantation due to the presence of morbid obesity. RESULTS Nine DDFR patients with a mean BMI of 45.9 kg/m2 underwent LSG for the treatment of obesity. Furthermore, all patients presented with hypertension and sleep apnea and six out nine were diabetics. In the immediate postoperative period, all patients were transferred to the intensive care unit (mean stay of 2.1 days). The only major adverse event was a delayed weaning from mechanical ventilation in one patient. The mean hospital stay was 5.5 days (3-12). The total weight loss (TWL) was 27.1, 33.6, and 39.5 kg at 6, 12, and 18 months, respectively. One patient underwent renal transplantation 18 months after LSG, and the other five patients were actively listed for kidney transplantation. CONCLUSIONS According to the results of this small sample series, LSG seems to be an effective and safe procedure in DDRF patients with concomitant obesity and can increase access to transplantation.

Abstract
BACKGROUND Bariatric surgery is widely accepted as the best treatment for obesity and type 2 diabetes mellitus (T2DM). The Roux-en-Y gastric bypass (RYGB) and the sleeve gastrectomy (SG) have become the predominant bariatric procedures in the USA over the last several years, although the most recent trends in selection are unknown. OBJECTIVE The objective of this study is to assess selection trends, readmission rates, and cost of bariatric procedures in the USA from 2012 to 2015. METHODS We used the Premier database from 2012 to 2015 to examine trends in incidence of RYGB, adjustable gastric banding (LAGB), and SG; readmissions; and cost. Multivariate regression was performed to identify predictors of readmission. RESULTS The proportion of SG went up from 38 to 63% while the RYGB decreased from 44 to 30% over this time period. LAGB has decreased in use from 13 to 2%. In comparison to RYGB, readmission was less likely for SG (OR 0.64), males (OR 0.91), and more likely for black race (OR 1.27). The overall proportion of patients seeking RYGB with type 2 diabetes was higher than with SG (36 versus 25%), but SG has now overtaken RYGB as the most common procedure among diabetics. The SG is less costly than RYGB ($11,183 versus $13,485). CONCLUSIONS There is a continued overall trend in the increased popularity of the SG and decreased utilization of the RYGB and LAGB, although growth of the SG appears to be slowing. This is also true among patients with type 2 diabetes mellitus. Regardless of surgery type, underinsured and African-American race were more likely to be readmitted.

Abstract
BACKGROUND Class III obesity is a global health emergency associated with an increase in the incidence of many other diseases such as type 2 diabetes mellitus, hypertension, hyperlipidemia, cancer, obstructive sleep apnea, nonalcoholic fatty liver disease, osteoarthritis, infertility, and mental health disorders. Minimal work has been published regarding the efficacy of laparoscopic sleeve gastrectomy (LSG) in the veteran population to surgically manage morbid obesity. DESIGN Retrospective analysis of LSG performed at a Veterans Affairs Medical Center (VAMC) between 2010 and 2017. Veterans were followed from their enrollment in the bariatric program until twelve months following LSG. The primary outcome of interest was excess and total weight loss with resolution of associated comorbidities. RESULTS Excess weight loss at nine and 12 months was 43.5% and 40.7% and total weight loss was 20.1% and 19.0%, respectively. LSG performed at a VAMC resulted in 86.9% improvement in type 2 diabetes mellitus and a 66.1% improvement in hypertension and 74.3% improvement in hyperlipidemia. Approximately 10.0% of diabetics obtained partial and 9.0% obtained complete resolution of their disease. Similarly, 22.0% of Veterans obtained partial and 13.0% obtained complete resolution from hypertension. Complete resolution from hyperlipidemia was achieved in 8.8% of Veterans. There were no postoperative complications or staple line leaks. CONCLUSION LSG is a safe and effective tool for morbid obesity with clinical and serological improvements for individuals who are unable to lose weight with medical management alone.

[PMID: 29625744 DOI: 10.1016/j.soard.2018.02.027] [Citation(s) in RCA: 148] [Impact Index Per Article: 24.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2017] [Revised: 02/25/2018] [Accepted: 02/28/2018] [Indexed: 02/07/2023]
Abstract
BACKGROUND The laparoscopic sleeve gastrectomy is now the most common bariatric operation in the United States and has become an established procedure in the armamentarium of the bariatric surgeon. However, this has happened without the strong support of long-term outcomes data, namely the rate of revision and durability of the weight loss. Newly published data from around the world are starting to show alarming trends in these 2 areas. This paper will examine the published and presented data with at least a 7-year follow-up. OBJECTIVES This is a meta-analysis on published data with at least 7 years of follow-up from the laparoscopic sleeve gastrectomy. SETTING Online published articles. METHODS We performed a meta-analysis of publications with at least 7 years of follow-up with the keywords "laparoscopic, bariatric, sleeve gastrectomy, sleeve, long-term, long, term, results, follow-up, follow up, conversion, 7 years, 8 years, 9 years, 10 years, 11 years." We queried the PubMed, MEDLINE, and ClinicalKey search engines, which included abstracts as well. The I2 statistic was used to determine the heterogeneity across the studies. In presence of heterogeneity, a random effect model using the Dersimonian and Laird method was used to estimate the pooled estimates. The results were summarized using effect size along with a 95% confidence interval (CI). Meta-regression was also used to assess the effect of body mass index and follow-up years on the incidence of recidivism at ≥7 years. RESULTS Nine cohort studies met the inclusion criteria, with a total of 2280 patients included initially. Only 652 patients had completed ≥7 years of follow-up. At ≥7 years, the long-term weight recidivism rate was estimated to be 27.8% (I2 = .60%; 95% CI: 22.8%-32.7%) with a range of 14% to 37%. The overall revision rate was estimated to be 19.9% (I2 = 93.8%; 95% CI: 11.3%-28.5%). This was broken down into 13.1% (I2 = 93.8%; 95% CI: 5.6%-20.6%) due to weight regain (5 studies) and 2.9% (I2 = 60.8%; 95% CI: 1%-4.9%) due to gastroesophageal reflux disease (5 studies). CONCLUSIONS Based on available data up to the beginning of 2017, bariatric surgeons should be aware of the long-term outcomes of the sleeve gastrectomy, especially regarding revisions and weight regain. It is incumbent on the surgeon to make sure that bariatric patients are truly informed regarding the long-term results of the sleeve gastrectomy.

Abstract
OBJECTIVE To review the complications of bariatric surgery and their diagnosis with intravenous contrast-enhanced multidetector computed tomography (MDCT). MATERIAL AND METHODS We retrospectively studied all patients who underwent gastric bypass or sleeve gastrectomy at our center during 2013 or 2014. We classified complications into early complications (appearing within 30 days of the intervention) and late complications. RESULTS We reviewed 155 cases and found 24 complications in 22 patients: 16 early complications (7 intraperitoneal hematomas, 5 anastomotic dehiscences, 2 intestinal obstructions, and 2 external hernias) and 8 late complications (3 internal hernias, 3 intestinal perforations, and 2 marginal ulcers). Two patients died. All of these complications were diagnosed with intravenous contrast-enhanced MDCT, except one, which required a barium transit study. CONCLUSION The rate of complications in bariatric surgery is high and the associated mortality is not negligible. Radiologists need to know the normal findings in these patients so they can quickly identify possible complications, most of which can be diagnosed with intravenous contrast-enhanced MDCT.

Abstract
BACKGROUND Rates of weight normalization and obesity remission after Roux-en-Y gastric bypass (GB) are unknown. This study evaluated weight loss, rates of achieving body mass index (BMI) <25 or 30 kg/m2, recidivism, and predictors of success following GB. METHODS We retrospectively studied weight and BMI at baseline, 2 and 6 months, and annually at 1-7 years in 219 patients undergoing GB at the University of Michigan from January 2008 to November 2010. RESULTS Follow-up was excellent for a population traditionally associated with high attrition rates with data availability of 157/219, 145/219, 144/219, 134/219, 123/219, 82/161, and 29/64 patients at 1-7 years, respectively. Mean baseline BMI was 47.0 kg/m2. Weight normalization (BMI <25 kg/m2) occurred in 2.3-6.8% of patients. More importantly, 47% of patients achieved remission of obesity (BMI <30 kg/m2) at some time point and 24% (52/219) at the last observed time point. BMI <30 kg/m2 was associated with a lower initial BMI and follow-up for more than 2 years. CONCLUSIONS Rates of weight normalization are low after GB; however, a large number of patients achieved BMI <30 kg/m2. While the percent total weight loss and excess weight loss are both quite high in the entire cohort and this is likely associated with significant health benefits, our results still underscore the need to address obesity with intensive clinical attention earlier in its course.

Abstract
BACKGROUND A primary measure of the success of a procedure is the whether or not additional surgery may be necessary. Multi-institutional studies regarding the need for reoperation after bariatric surgery are scarce. OBJECTIVES The purpose of this study is to evaluate the rate of revisions/conversions (RC) after 3 common bariatric procedures over 10 years in the state of New York. SETTING University Hospital, involving a large database in New York State. METHODS The Statewide Planning and Research Cooperative System database was used to identify all patients undergoing laparoscopic adjustable gastric banding (LAGB), sleeve gastrectomy (SG), and Roux-en-Y gastric bypass (RYGB) between 2004 and 2010. Patients were followed for RC to other bariatric procedures for at least 4 years (up to 2014). Multivariable cox proportional hazard regression analysis was performed to identify risk factors for additional surgery after each common bariatric procedure. Multivariable logistic regression was used to check the factors associated with having ≥2 follow-up procedures. RESULTS There were 40,994 bariatric procedures with 16,444 LAGB, 22,769 RYGB, and 1781 SG. Rate of RC was 26.0% for LAGB, 9.8% for SG, and 4.9% for RYGB. Multiple RC ( = />2) were more common for LAGB (5.7% for LAGB, .5% for RYGB, and .2% for LSG). Band revision/replacements required further procedures compared with patients who underwent conversion to RYGB/SG (939 compared with 48 procedures). Majority of RC were not performed at initial institution (68.2% of LAGB patients, 75.9% for RYGB, 63.7% of SG). Risk factors for multiple procedures included surgery type, as LAGB was more likely to have multiple RC. CONCLUSIONS Reoperation was common for LAGB, but less common for RYGB (4.9%) and SG (9.8%). RC rate are almost twice after SG than after RYGB. LAGB had the highest rate (5.7%) of multiple reoperations. Conversion was the procedure of choice after a failed LAGB.

Abstract
BACKGROUND Laparoscopic Roux-en-Y gastric bypass (LRYGB) produces durable and clinically significant weight loss. We aim to characterize the trajectory of weight loss, and demonstrate the predictive ability of three-month performance on final weight loss. METHODS Retrospective analysis of 1097 consecutive LRYGB patients allowed for assessment of conformity of various weight loss trajectory models. Establishing exponential decay as the optimal fit, initial, three-month and final BMI values were used to determine empiric rate constants (λ3). Empirically derived weight loss curves and associated rate constants (λ) were generated. RESULTS Exponential decay optimally characterizes post-LRYGB weight loss trajectory. Final weight loss can be characterized by λ3, as well as by the demographics black race (P = 0.008) and initial BMI (P < 0.001). Stratification by three-month weight loss allowed derivation of weight loss trajectory curves to predict weight at any point until and including plateau. CONCLUSIONS Weight loss after LRYGB conforms well to exponential decay, and postoperative trajectory can thus be predicted early. This allows the clinician early identification and intervention upon patients at risk of poor performance.

Abstract
BACKGROUND Weight regain and type-2 diabetes relapse has been reported in a significant proportion of vertical sleeve gastrectomy (VSG) patients in some studies, but definitive conclusions regarding the long-term comparative effectiveness of VSG and Roux-en-Y gastric bypass (RYGB) surgery are lacking both in humans and rodent models. This study's objective was to compare the effects of murine models of VSG and RYGB surgery on body weight, body composition, food intake, energy expenditure, and glycemic control. METHODS VSG, RYGB, and sham surgery was performed in high-fat diet-induced obese mice, and the effects on body weight and glycemic control were observed for a period of 12 weeks. RESULTS After the initial weight loss, VSG mice regained significant amounts of body weight and fat mass that were only marginally lower than in sham-operated mice. In contrast, RYGB produced sustained loss of body weight and fat mass up to 12 weeks and drastically improved fasting insulin and HOMA-IR compared with sham-operated mice. Using weight-matched control groups, we also found that the adaptive hypometabolic response to weight loss was blunted by both VSG and RYGB, and that despite large weight/fat regain, fasting insulin and HOMA-IR were markedly improved, but not reversed, in VSG mice. CONCLUSIONS VSG is less effective to lastingly suppress body weight and improve glycemic control compared with RYGB in mice. Given similar observations in many human studies, the run towards replacing RYGB with VSG is premature and should await carefully controlled randomized long-term trials with VSG and RYGB.

Abstract
Obesity is a worldwide epidemic, and those suffering from obesity have increased morbidity and mortality rates. There are various causes of obesity and many treatment options for patients suffering from obesity, including nonsurgical treatments. However, bariatric surgery is often the best choice for optimal weight loss and the attenuation of comorbidities. Currently, laparoscopic sleeve gastrectomy is the most common type of bariatric surgery in the United States due to its technical simplicity, feasibility, and overall positive outcomes. This article discusses bariatric surgical criteria and selection, expected perioperative course, potential complications after surgery, and nursing implications for the care of bariatric patients. A case report is used to exemplify stages of surgical care and follow-up treatment for patients who undergo laparoscopic sleeve gastrectomy.

Abstract
PURPOSE OF REVIEW Patients with type 1 diabetes (T1D) are typically viewed as lean individuals. However, recent reports showed that their obesity rate surpassed that of the general population. Patients with T1D who show clinical signs of type 2 diabetes such as obesity and insulin resistance are considered to have "double diabetes." This review explains the mechanisms of weight gain in patients with T1D and how to manage it. RECENT FINDINGS Weight management in T1D can be successfully achieved in real-world clinical practice. Nutrition therapy includes reducing energy intake and providing a structured nutrition plan that is lower in carbohydrates and glycemic index and higher in fiber and lean protein. The exercise plan should include combination stretching as well as aerobic and resistance exercises to maintain muscle mass. Dynamic adjustment of insulin doses is necessary during weight management. Addition of anti-obesity medications may be considered. If medical weight reduction is not achieved, bariatric surgery may also be considered.

Abstract
PURPOSE OF REVIEW The review assesses the role of non-pharmacologic therapy for obesity and chronic kidney disease (CKD) associated refractory hypertension (rf HTN). RECENT FINDINGS Hypertensive patients with markedly heightened sympathetic nervous system (SNS) activity are prone to develop refractory hypertension (rfHTN). Patients with obesity and chronic kidney disease (CKD)-associated HTN have particularly heightened SNS activity and are at high risk of rfHTN. The role of bariatric surgery is increasingly recognized in treatment of obesity. Current evidence advocates for a greater role of bariatric surgery in the management of obesity-associated HTN. In contrast, renal denervation does not appear have a role in the management of obesity or CKD-associated HTN. The role of baroreflex activation as adjunctive anti-hypertensive therapy remains to be defined.

Abstract
This review article focuses on gastroduodenal and pancreatic surgeries with the goal of identifying radiologic findings that translate to important surgical considerations. The topics covered include partial gastrectomy with reconstruction techniques, total gastrectomy, pancreaticoduodenectomy, and pancreaticojejunostomy. Indications, contraindications, surgical techniques, and postoperative imaging are described within each of these topics. Knowledge of these surgical techniques is extremely helpful for the interpreting radiologists to identify expected postoperative anatomy and related complications that would remain clinically relevant to our surgical colleagues and direct timely patient management.

Abstract
Bariatric surgery is highly successful in improving health compared to conventional dietary treatments. It has been suggested that the gut microbiota is a relevant factor in weight loss after bariatric surgery. Considering that bariatric procedures cause different rearrangements of the digestive tract, they probably have different effects on the gut microbiota. In this study, we compared the impact of medical treatment, sleeve gastrectomy and Roux-en-Y gastric bypass on the gut microbiota from obese subjects. Anthropometric and clinical parameters were registered before, 6 and 12 months after treatment. Fecal samples were collected and microbiota composition was studied before and six months post treatment using 16S rRNA gene sequencing and qPCR. In comparison to dietary treatment, changes in intestinal microbiota were more pronounced in patients subjected to surgery, observing a bloom in Proteobacteria. Interestingly, Bacteroidetes abundance was largely different after six months of each surgical procedure. Furthermore, changes in weight and BMI, or glucose metabolism, correlated positively with changes in these two phyla in these surgical procedures. These results indicate that distinct surgical procedures alter the gut microbiota differently, and changes in gut microbiota might contribute to health improvement. This study contributes to our understanding of the impact of weight loss surgery on the gut microbiota, and could be used to replicate this effect using targeted therapies.
