Abstract
PURPOSE Bariatric surgery is currently considered the most effective and durable treatment option for morbid obesity. Laparoscopic sleeve gastrectomy (LSG) has become a popular technique and may currently be the most frequently practiced surgical operation to treat obesity. However, no objective analyses of its learning curve have been reported. OBJECTIVE to analyze the learning curve for LSG. MATERIALS AND METHODS We included all LSGs performed in our hospital (University Hospital, Spain; Public Practice) from April 2013 to February 2016. The learning curve for LSG was evaluated using cumulative sum (CUSUM) analysis. All variables among the learning curve phases were compared. RESULTS According to the CUSUM analysis, the learning curve was divided into three unique phases: early learning (the initial 26 patients), acquisition of skills (the middle 30 patients), and mastery of technique (the final 56 patients). The operative time and gastric stenosis significantly decreased with progression of the learning curve without differences in the 30-day postoperative complication rate, postoperative stay, or weight loss. CONCLUSION According to this study, the learning curve for LSG can be divided into 3 distinct phases, and about 25 patients are needed to demonstrate an improvement in surgical skill.

Abstract
To evaluate whether the learning curve for sleeve gastrectomy could be completed after 50 cases. First 100 patients undergoing LSG under a newly trained laparoscopic surgeon were included in this study and divided into two groups of 50 consecutive patients each. Perioperative outcomes were compared to recently introduced global benchmarks. Short-term weight loss was calculated as Total Weight Loss Percent (%TWL) and complications were classified in accordance with the Clavien–Dindo classification. CUSUM analysis was performed for operative time and hospital stay. Mean preoperative age and BMI were 41.8 ± 10.3 years and 42.9 ± 5.4 kg/m2, respectively. Demographics and rate of patients with previous surgery were comparable preoperatively in the two groups. Mean operative time was 92.1 ± 19.3 min and hospital stay was 3.4 ± 0.6 days as per our standard protocol of discharge. Uneventful postoperative course was recorded in 93% of patients and only one case of staple line leak was registered in the first 50 cases (group 1). No statistical difference in BMI and %TWL was found between the two groups at any time of follow-up. Comparison between two groups showed a significant reduction in hospital stay and operative time after the first 50 LSGs (p < 0.05). LSG can be performed by newly trained surgeons proctored by senior tutors. At least 50 cases are needed to meet global benchmark cut-offs and few more cases may be required to reach the plateau of the learning curve.

Abstract
BACKGROUND The most commonly performed bariatric procedures are laparoscopic Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (LSG). Impact of learning curves on operative outcome has been well shown, but the necessary learning curves have not been clearly defined. This study provides a systematic review of the literature and proposes a standardization of phases of learning curves for RYGB and LSG. METHODS A systematic literature search was performed using PubMed, Web of Science, and CENTRAL databases. All studies specifying a number or range of approaches to characterize the learning curve for RYGB and LSG were selected. RESULTS A total of 28 publications related to learning curves for 27,770 performed bariatric surgeries were included. Parameters used to determine the learning curve were operative time, complications, conversions, length of stay, and blood loss. Learning curve range was 30-500 (RYGB) and 30-200 operations (LSG) according to different definitions and respective phases of learning curves. Learning phases described the number of procedures necessary to achieve predefined skill levels, such as competency, proficiency, and mastery. CONCLUSIONS Definitions of learning curves for bariatric surgery are heterogeneous. Introduction of the three skill phases competency, proficiency, and mastery is proposed to provide a standardized definition using multiple outcome variables to enable better comparison in the future. These levels are reached after 30-70, 70-150, and up to 500 RYGB, and after 30-50, 60-100, and 100-200 LSG. Training curricula, previous laparoscopic experience, and high procedure volume are hallmarks for successful outcomes during the learning curve.

Abstract
Purpose To analyze the effectiveness of vertical gastrectomy in the treatment of
obese patients, adherence to clinical follow-up and the influence of factors
such as gender and age. Methods This is a retrospective, observational and descriptive study, conducted with
patients undergoing vertical gastrectomy, operated at Hospital São Domingos,
between January 2016 and July 2018. Results Most patients undergoing vertical gastrectomy were female (n = 193, 72.28%)
and had a mean age of37.11 ± 8.96 years old. The loss of follow-up was
56.18%. Among adherent patients (n = 117; 43.82%), most patients were female
(n = 89; 76.07%) and had a mean age of 37.92 ± 9.85 years old. The mean body
mass index (BMI) of the adherents in the preoperative was 37.85 ± 3.72
kg/m2. Both BMI and excess weight (EW) showed a statistically
significant difference between pre- and postoperative period. Percentage of
excess weight loss (% EWL) was satisfactory for 96.6% of adherent patients.
Older patients had a statistically significant lower % EWL compared to the
other groups. Conclusions Vertical gastrectomy was effective in the treatment of obese patients, with
significant weight loss.

Abstract
Endoscopic sleeve gastroplasty (ESG) is a therapeutic endoscopic technique for reducing the size of the gastric reservoir in obese patients, using a full-thickness endoscopic suturing device. The effectiveness of ESG in weight loss is significantly greater than that of high-intensity diet and lifestyle therapy and lower than that of laparoscopic sleeve gastrectomy (LSG). The efficacy at 12 months after ESG in terms of percentage of total body weight loss and excess body weight loss was approximately 16% and 60%, respectively. The well-known predictive factors for increased weight loss by ESG are good compliance with regular monitoring and post-procedure care involving a multidisciplinary team approach. Although the underlying mechanism of weight loss induced by ESG is debatable, delayed gastric emptying and early satiation are some of the proposed mechanisms. The pooled rate of adverse events after ESG reported in several meta-analysis studies ranged from 1.5% to 2.3% and the incidence of new-onset gastroesophageal reflux disease after ESG was negligible, indicating that ESG has a superior safety profile to LSG. Moreover, ESG reduced the risk of obesity-related metabolic comorbidities, evidenced by the reduction in HbA1c level, systolic blood pressure, triglyceride level, and risk of hepatic steatosis and fibrosis; it even improved the quality of life. ESG could be considered safe and qualify as an alternative treatment to LSG.

Abstract
Bariatric revisional surgery represents an important new issue for obese patients because of the considerable rate of failure and complications following bariatric surgery. As the frequency of bariatric procedures increases, so too does the incidence of revisional surgery, which has become becoming increasingly important. The surgeon must know the indications and the results of the various revisional procedures in order to best guide the therapeutic decision. The current challenge is to correctly select the patients for revisional surgery and to choose the appropriate procedure in each case. Multidisciplinary management is essential to patient re-assessment and to prepare the patient for a re- intervention. The objective of this update, based on data from all the most recent studies concerning revisional surgery, is to guide the surgeon in the choice of the revisional procedure, depending on patient characteristics, co-morbidities, the previously performed procedure, the type of failure or complication observed, but also on the surgeon's own habits and the center's expertise. The collected results show that revisional surgery is difficult, with higher complication rates and weight-loss results that are often lower than those of first-intent surgery. For these reasons, patient selection must be rigorous and multidisciplinary and the management in expert centers of these difficult situations must be encouraged.

Abstract
INTRODUCTION Laparoscopic sleeve gastrectomy (LSG) is the most popular bariatric procedure worldwide. A tremendous recent increase in the number of LSGs has not been driven by an accurate learning process, especially in low volume bariatric centers. The cumulative-sum (CUSUM) method is an effective analysis of the learning process, taking intraoperative and postoperative variables into account. This study was aimed at establishing a CUSUM learning curve for LSG in order to define the number of procedures needed to achieve sufficient surgical skill. METHODS All LSGs performed by a single general surgeon between September 2014 and November 2017 were considered. We hypothesized that the key t variables related to the LSG learning process (LP) are: operative time (OT), intraoperative complications or difficulties, need for expert assistance, length of hospital stay (LOS), and 3-month postoperative morbidity. All of these parameters are binary variables analyzed with the risk-adjusted CUSUM method. Two groups, learning group (LG) and experienced group (EG), were identified and compared by univariate analysis. Multivariate analysis was performed to identify the variables most closely associated with operative time and surgical success. One-year weight loss outcomes were likewise analyzed. RESULTS One hundred and ten (110) consecutive LSGs were considered. CUSUM-LSG showed that the mean number of consecutive interventions necessary to reach proficiency in LSG was 58. In multivariate analysis, surgical success was negatively correlated with longer operative time and need for expert assistance. Body mass index was not correlated with surgical success. CONCLUSION Fifty-eight LSG procedures were required to achieve surgical skill. Operative time and the need for expert assistance were variables most closely associated with surgical success. ACGME COMPETENCY Practice-based learning and improvement.

Abstract
PURPOSE Endoscopic sleeve gastroplasty (ESG) has grown in popularity as a potential minimally invasive bariatric procedure with acceptable short- and medium-term outcomes. This review aims to assess the safety and weight loss outcomes of ESG and compare it with laparoscopic sleeve gastrectomy (LSG). MATERIAL AND METHODS A comprehensive search of MEDLINE, EMBASE, Cochrane and World Wide Web was conducted. RESULTS Five studies were reviewed, three ESG cohort studies and two case-matched cohort studies comparing ESG with LSG. Total unique ESG and LSG patients were 1451 and 203, respectively. All papers demonstrated a modest short-term total body weight loss (TBWL%) at 6 months ranging from 13.7 to 15.2% for ESG. Comparably, the two LSG papers demonstrated a superior TBWL% of 23.5 and 23.6% at 6 months, with one paper reporting a 12-month TBWL% of 29.3%. Two ESG papers reported medium-term results at 18 and 24 months of 14.8% and 18.6%, respectively. Excluding Clavien-Dindo 1 complications, ESG had a complication rate between 2.0 and 2.7%, while comparatively, LSG had a complication rate between 9.2 and 16.9% (current literature reported as 8.7%). In both procedures, there were no grade IV or V complications. CONCLUSION ESG when compared with LSG has lower short-term weight loss outcomes with fewer complications. Weight loss results for ESG appear to plateau after the 1-year mark. The future and uptake of ESG as a minimally invasive bariatric procedure will be determined by its long-term data on potential weight loss sustainability.

Abstract
OBJECTIVE To determine the clinical, radiographic, and endoscopic findings of sleeve stenosis after sleeve gastrectomy and to correlate treatment with outcomes. METHODS We identified 43 patients who underwent barium studies to evaluate upper GI symptoms after laparoscopic sleeve gastrectomy. The clinical, radiographic, and endoscopic findings were reviewed and correlated with treatment and outcomes. RESULTS 26 patients (60%) had sleeve stenoses. All stenoses appeared as short segments of smooth, tapered narrowing, with a mean length of 8.0 mm and mean width of 7.5 mm, and 24 (92%) were located in the proximal or distal third of the sleeve. 23 patients (88%) had upstream dilation, and 1 (4%) had retained food proximal to the stenosis. 23 (70%) of 33 patients with obstructive symptoms and 3 (30%) of 10 without obstructive symptoms had sleeve stenoses. Endoscopy revealed sleeve stenosis in 8 (67%) of 12 patients with radiographic stenosis. Endoscopic dilation resulted in improvement/resolution of symptoms in seven (88%) of 8 patients. CONCLUSION Sleeve stenosis after sleeve gastrectomy was characterized radiographically by a short segment of smooth, tapered narrowing, typically in the proximal or distal third of the sleeve. Approximately, 70% of patients with obstructive symptoms and 30% with non-obstructive symptoms had sleeve stenosis. One-third of radiographically diagnosed stenoses were not seen at endoscopy. The barium study, therefore, is a useful test for sleeve stenosis in patients with obstructive or nonobstructive symptoms after sleeve gastrectomy. Advances in knowledge: This article describes the appearance and location of sleeve stenoses after laparoscopic sleeve gastrectomy and the clinical presentation and treatment options for these patients.

Background and Aims: The aim of this study was to evaluate the long-term (5-year follow-up) results of laparoscopic sleeve gastrectomy in terms of weight loss and obesity-related comorbidities, as well as the risk factors associated with postoperative nutritional deficiencies. Material and Methods: The first 99 consecutive patients who underwent laparoscopic sleeve gastrectomy for the treatment of morbid obesity between October 2008 and August 2011 at Tartu University Hospital were followed prospectively in cohort study. The outpatient hospital follow-up visits were conducted at 3 months, 1 year, and 5 years postoperatively. At 5 years, the follow-up rate was 90.9%; 86 laparoscopic sleeve gastrectomy patients were included in final analysis. Results: The mean excess weight loss (%EWL) was 44.3% ± 13.0%, 75.8% ± 23.1%, and 61.0% ± 24.3% at 3 months, 1 year, and 5 years, respectively. A linear association between preoperative weight and weight at 5 years was found. Remission rates at 5-year follow-up for type 2 diabetes, hypertension, dyslipidemia, and obstructive sleep apnea were 68.8%, 32.7%, 27.4%, and 61.5%, respectively (all p < 0.05). There was a statistical difference (p < 0.05) in the dynamics of triglyceride, low-density lipoprotein, and high-density lipoprotein level at 5-year follow-up but the level of total cholesterol did not show significant improvement. The risk for cumulative iron, vitamin B12 deficiency, and anemia was 20%, 48%, and 28%, respectively. Conclusion: In conclusion, laparoscopic sleeve gastrectomy ensured long-term excess weight loss 61.0% at 5 years. Laparoscopic sleeve gastrectomy has a long-term effect on significant improvement in the median values of triglycerides, low-density lipoproteins, and high-density lipoproteins, but not on total cholesterol levels. There is a risk of postoperative vitamin B12 and iron deficiency.

Abstract
BACKGROUND The laparoscopic mini-gastric bypass is a newly emerged surgical procedure in recent years. Owe to safe and simple process and effective outcomes, laparoscopic mini-gastric bypass has quickly become one of the most popular procedures in some countries. The safety and effectiveness of laparoscopic mini-gastric bypass versus laparoscopic sleeve gastrectomy remain unclear. METHODS A systematic literature search was performed in PubMed, Embase, Cochrane library from inception to May 20, 2017. The methodological quality of Randomized Controlled Trials and non-Randomized Controlled Trials were, respectively, assessed by Cochrane Collaboration's tool for assessing risk of bias and Newcastle-Ottawa scale. The meta-analysis was performed by RevMan 5.3 software. RESULTS Patients receiving mini-gastric bypass had a lot of advantageous indexes than patients receiving sleeve gastrectomy, such as higher 1-year EWL% (excess weight loss), higher 5-year EWL%, higher T2DM remission rate, higher hypertension remission rate, higher obstructive sleep apnea (OSA) remission rate, lower osteoarthritis remission rate, lower leakage rate, lower overall late complications rate, higher ulcer rate, lower gastroesophageal reflux disease (GERD) rate, shorter hospital stay and lower revision rate. No significant statistical difference was observed on overall early complications rate, bleed rate, vomiting rate, anemia rate, and operation time between mini-gastric bypass and sleeve gastrectomy. CONCLUSION Mini-gastric bypass is a simpler, safer, and more effective bariatric procedure than laparoscopic sleeve gastrectomy. Due to the biased data, small sample size and short follow-up time, our results may be unreliable. Large sample and multicenter RCT is needed to compare the effectiveness and safety between mini-gastric bypass and sleeve gastrectomy. Future study should also focus on bile reflux, remnant gastric cancer, and long term effectiveness of mini-gastric bypass.

Abstract
PURPOSE The use of laparoscopic sleeve gastrectomy (LSG) is increasing worldwide. Although post-LSG gastric stenosis (GS) is less frequent, it has not been well defined and lacks standardized management procedures. The objective of the present study was to describe a series of patients with GS symptoms after LSG and to develop a standardized management procedure for this complication. METHODS We performed a retrospective analysis of a prospective database of patients presenting with GS after LSG procedures performed between January 2008 and March 2014. The primary efficacy criterion was the frequency of post-LSG GS. GS was classified as functional (i.e. a gastric twist) or organic. The secondary efficacy criteria included the time interval between LSG and diagnosis of GS, the type of stenosis, the type of management, and the follow-up data. RESULTS During the study period, 1210 patients underwent primary or secondary LSG. Seventeen patients had post-operative symptoms of GS (1.4%); one patient had achalasia that had not been diagnosed preoperatively and thus was excluded from our analysis. The median time interval between LSG and diagnosis of GS was 47.2 days (1-114). Eleven patients had organic GS and six had functional GS. Seven patients required nutritional support. Endoscopic treatment was successful in 15 patients (88.2%) after balloon dilatation (n = 13) or insertion of a covered stent (n = 2). Two of the 15 patients required conversion to Roux-en-Y gastric bypass (11.8%). CONCLUSION GS after LSG is a rare complication but requires standardized management. Most cases can be treated successfully with endoscopic balloon dilatation.

Abstract
Laparoscopic sleeve gastrectomy has rapidly been adopted as a primary surgical procedure in bariatric patients. The technique of multiport sleeve gastrectomy is described using 4 to 6 ports and an additional port for a liver retractor. A technique of single-port sleeve gastrectomy has been described, the principal advantages of which appear to reduced postoperative pain and an improved cosmetic outcome. In this paper we describe a novel, and easily reproducible technique for the performance of a sleeve gastrectomy using only 3 ports that does not compromise the procedure and may offset the disadvantages of a multiport technique.

Abstract
Sleeve gastrectomy (SG) has become one of the most commonly used bariatric procedures worldwide. However, data regarding long-term results remain insufficient. The aim of this study was to review the long-term results after SG. We conducted a comprehensive literature search of Medline and the Cochrane Library for articles published until May 2016 on the long-term results (>5 yr) after SG. Studies representing outcomes of SG were included if they reported≥5-year results that contained at least one outcome of interest-weight loss, co-morbidities, long-term complications, or quality of life-and SG was performed as a primary procedure. Of the 297 initially identified articles, 277 studies met the exclusion criteria, and 20 met the inclusion criteria. SG was performed on 2713 patients and 1626 patients reached the≥5-year follow-up point. Among the patients, 71.3% were women and 28.7% were men. The mean preoperative body mass index was 46.9 kg/m2. The duration of follow-up ranged 5 to 11 years. The mean 5-year follow-up rate was 66% (range, 57%-100%). The mean percentage excess weight loss was 58.4%, 59.5%, 56.6%, 56.4%, and 62.5% at 5, 6, 7, 8, and 11 years, respectively. Five years after SG, the resolution or improvement of type 2 diabetes was observed in 77.8% of patients, and arterial hypertension, dyslipidemia, obstructive sleep apnea, gastroesophageal reflux disease, and degenerative joint diseases had improved or resolved in 68.0%, 65.9%, 75.8%, 30.6%, and 55.7% of patients, respectively. This systematic review suggests that SG can lead to substantial and lasting excess weight loss and significant improvement in obesity-related co-morbidities. However, the lack of randomized clinical trials, low follow-up rates, and poorly reported data regarding co-morbidities and quality of life in many of the studies indicate that these findings should be interpreted with caution.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is a worldwide surgical procedure for morbid obesity. However patients selection is still anecdotal. The aim of this study is to analyse clinical and anthropometric parameters correlated with LSG and to check the validity of this procedure for different categories of obese patients. METHODS Two-hundred one consecutive patients were submitted to LSG as a primary bariatric procedure between 2008 and 2014. One year follow-up was completed in 159 patients. Smaller groups of patients completed 2 and 3 years follow-up (78, 46 patients respectively). Median preoperative body mass index (BMI) was 45.4 kg/m2 (range: 34.8-73.8); 135 patients (80%) had one or more comorbidities. Potential correlations between age, gender, preoperative BMI, preoperative excess weight, early excess weight loss (EWL) and 1 and 3 year-EWL were investigated. RESULTS All procedures were regularly completed with laparoscopic approach without conversion to laparotomy. Postoperative complications occurred in six patients (3.7%); no postoperative mortality was observed. Median one-year BMI and EWL were 32.8 kg/m2 and 55.34%, respectively. Three year-EWL was significantly influenced by age, and early EWL. A complete normalization of glycemic levels after the three-year follow-up was also observed in high percentage of diabetic patients. In patients with preoperative BMI>50 kg/m2 we observed most failure cases in terms of EWL and the worst metabolic results. CONCLUSIONS Our experience indicates that LSG is a safe procedure with satisfactory three-year late weight loss in patients with preoperative BMI <50 kg/m2. Promising results, in terms of improvements of comorbidities, were also observed. These results make LSG one of the most attractive first stage surgical procedure for morbid obesity.

Abstract
BACKGROUND Despite the health benefits of bariatric surgery (BS) extend beyond WL, better understanding of the WL response may help improve the outcomes of BS. In this context, we aimed to assess patterns within the variability of weight loss (WL) after Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). METHODS WL data from 658 subjects that underwent RYGB (n = 464) or SG (n = 194) as first BS were analyzed. Based on excess WL (EWL), subjects were categorized as good WL responders (EWL ≥ 50 % at nadir weight and throughout follow-up), primarily poor WL responders (1-PWL:EWL < 50 % at nadir weight and thereafter), and secondarily poor WL responders (2-PWL:EWL ≥ 50 % at nadir weight, but <50 % at last follow-up visit). Predictors associated with different WL outcomes were ascertained using regression analysis. RESULTS Median follow-up was 55.7 months. Nadir EWL ranged 12.4-143.6 %; last follow-up visit EWL ranged -22.1-143.6 % and weight regain (WR) ranged 0-64.1 kg. Good WL was found in 75.7 of the cohort. 1-PWL response (4.7 %) was characterized by lesser WL but similar WR as compared to good WL and was associated with larger BMI and diabetes prior to surgery. 2-PWL response (19.6 %) was characterized by larger WR as compared to the other groups and was more common following SG. Lesser percentage of medical appointments kept was associated with 1-PWL and 2-PWL. CONCLUSION Our data show the high inter-individual variability of the WL response at mid-term after RYGB and SG and that poor WL after BS could be illustrated by two different patterns, characterized either by sustained limited WL (1-PWL), or pronounced weight regain (2-PWL).

Abstract
BACKGROUND For the purpose of building best practice guidelines, an international expert panel was surveyed in 2014 and compared with the 2011 Sleeve Gastrectomy Consensus and with survey data culled from a general surgeon audience. OBJECTIVES To measure advancement on aspects of laparoscopic sleeve gastrectomy and identify current best practices. SETTING International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) 2014, Fifth International Summit for Laparoscopic Sleeve Gastrectomy, Montréal, Canada. METHODS In August 2014, expert surgeons (based on having performed>1000 cases) completed an online anonymous survey. Identical survey questions were then administered to general surgeon attendees. RESULTS One hundred twenty bariatric surgeons completed the expert survey, along with 103 bariatric surgeons from IFSO 2014 general surgeon audience. The following indications were endorsed: as a stand-alone procedure (97.5%); in high-risk patients (92.4%); in kidney and liver transplant candidates (91.6%); in patients with metabolic syndrome (83.8%); body mass index 30-35 with associated co-morbidities (79.8%); in patients with inflammatory bowel disease (87.4%); and in the elderly (89.1%). Significant differences existed between the expert and general surgeons groups in endorsing several contraindications: Barrett's esophagus (80.0% versus 31.3% [P<.001]), gastroesophageal reflux disease (23.3% versus 52.5% [P<.001]), hiatal hernias (11.7% versus 54.0% [P<.001]), and body mass index>60 kg/m(2) (5.0% versus 28.0% [P<.001]). Average reported weight loss outcomes 5 years postoperative were significantly higher for the expert surgeons group (P = .005), as were reported stricture (P = .001) and leakage (P = .005) rates. The following significant differences exist between 2014 and 2011 expert surgeons: Patients with gastroesophageal reflux disease should have pH and manometry study pre-laparoscopic sleeve gastrectomy (32.8% versus 50.0%; P = .033); it is important to take down the vessels before resection (88.1% versus 81.8%; P = .025); it is acceptable to buttress (81.4% versus 77.3%; P<.001); the smaller the bougie size and tighter the sleeve, the higher the incidence of leaks (78.8% versus 65.2%; P = .006). CONCLUSION This study highlights areas of new and improved best practices on various aspects of laparoscopic sleeve gastrectomy performance among experts from 2011 and 2014 and among the current general surgeon population.

Abstract
The aim of this study is to present our preliminary experience with indocyanine green fluorescence (IGF) imaging in laparoscopic sleeve gastrectomy. After dissection of the greater curve sleeve, gastrectomy is performed using a linear articulated stapler. Once the stomach is resected, an indocyanine green solution is prepared and injected in a periferic vein. A laparoscopic system with a high-definition camera system connected to a laparoscope equipped with a specific filter for optimal detection of the near-infrared fluorescence was used at all times as previously reported in a paper of Boni et al. A methylene blue test is routinely performed after near-infrared fluorescence, and a routine gastrografin upper gastrointestinal study is performed on postoperative day 2. We retrospectively identified 15 patients undergoing laparoscopic sleeve gastrectomy between April and October 2014. IGF imaging was used for all patients. A regular and homogeneous perfusion was observed along the entire gastric sleeve including the esophago-gastric junction. On the contrary, the excised specimen appeared devascularized at IGF imaging as expected. Intraoperative methylene blue test was negative in all cases. The contrast swallow did not document any leak. Neither clinical leak nor other complications occurred postoperatively (minimum follow-up of 2 months). IGF is a recent development in minimally invasive surgery. In this preliminary experience, IGF results resemble to intraoperative methylene blue test and postoperative contrast swallow ones. IGF allows a real-time assessment and gives a direct image of tissue perfusion and vascularization. Moreover, IGF may be helpful to explain the exact pathogenesis of gastric leak.

Abstract
Revisional bariatric surgery following laparoscopic sleeve gastrectomy (LSG) failure presents a clinical challenge for the bariatric surgeon. Limited evidence exists in selecting the appropriate revisional operation: laparoscopic gastric bypass (LGB), laparoscopic re-sleeve gastrectomy (LRSG), or other surgical intervention (OSI), to address weight regain. We systematically reviewed the literature to assess the efficacy of existing revisional surgery. A comprehensive search of electronic databases (e.g., Medline, Embase, Scopus, Web of Science, and the Cochrane Library) was completed. All randomized controlled trials, non-randomized comparison study, and case series were included. Eleven primary studies (218 patients) were identified and included in the systematic review. Studies were grouped into three main categories: LGB, LRSG, and OSI. Preoperative body mass index (BMI) was 41.9 kg/m(2) (LGB), 38.5 kg/m(2) (LRSG), and 44.4 kg/m(2) (OSI). After conversion to LGB, BMI decreased to 33.7 and 35.7 kg/m(2) at 12 and 24 months of follow-up, respectively. Excess weight loss (EWL) was 60 and 48 % over the same periods. After LRSG, BMI decreased to 30.4 and 35.3 kg/m(2) with corresponding EWL of 68 and 44 %, at 12 and 24 months, respectively. After OSI, BMI decreased to 27.3 kg/m(2) with an EWL of 75 % at 24-month follow-up but could not be analyzed due to incomplete data collection in primary studies. Both LGB and LRSG achieve effective weight loss following failed LSG. The less technically challenging nature of LRSG may be more widely applicable. Further research is required to elicit sustainability in long-term weight loss benefits.

Abstract
Background: Bariatric procedures are effective options for weight loss (WL) in the morbidly obese. However, some patients fail to lose any weight after bariatric surgery, and mid-term weight maintenance is variable. The aim of this study was to investigate whether initial WL could predict mid-term weight maintenance. Methods: Eighty patients were enrolled, of whom 44 were treated with the BioEnterics Intragastric Balloon (BIB), 21 with laparoscopic adjustable gastric lap-banding (LAGB), and 15 with laparoscopic sleeve gastrectomy (LSG). Percentage of body WL and percentage of excess weight loss (EWL) were calculated at baseline and after 1, 3, 6, and 12 months. Successful WL was defined as EWL >20% for patients treated with BIB and >50% for patients treated with LAGB and SG. Results: Success in the 6th and 12th month was achieved in 80% and 58% of patients in the BIB group, 33% and 40% in the LAGB group, and 60% and 73% in the LSG group. In the BIB group, WL in the 1st month correlated positively with WL at the 6th and 12th month, and an initial WL >6.5% best predicted success (sensitivity 50%, specificity 80%). A similar association was observed in the LAGB group at the 6th and 12th month and an initial WL >9.4% best predicted success (sensitivity 90.0%, specificity 81.2%). In patients treated with LSG, WL in the 3rd month correlated positively with EWL at the 6th and 12th month, with a cutoff value of 17% (sensitivity 66.7%, specificity 100%). Conclusions: WL in the 1st month in patients treated with BIB and LAGB and WL in the 3rd month in patients treated with LSG could be used as a prognostic factor to predict mid-term weight maintenance.

Abstract
Purpose Laparoscopic sleeve gastrectomy (LSG) has been gaining marked popularity as a stand-alone treatment for morbid obesity. This study aimed to evaluate the midterm outcomes and efficacy of LSG performed at a single center in Korea. Methods The records of 192 consecutive patients who underwent LSG between April 2009 and December 2012 were retrospectively reviewed. The patients' demographics and surgical outcomes including anthropometric data were analyzed. Results The mean preoperative body mass index was 40.0 ± 7.2 kg/m2, and 120 patients (62.5%) had at least one obesity-related comorbidity. Three patients (1.6%) required endoscopic or surgical intervention to manage postoperative bleeding or leakage. At the postoperative 1-, 2-, 3-, and 4-year follow-ups, the mean percent of excess weight loss (%EWL) values were 72.6%, 80.6%, 71.1%, and 57.8%, respectively, with follow-up rates of 81%, 56%, 58%, and 30% respectively. The overall mean %EWL reached 68.3% ± 27.2% at a mean follow-up of 25 months. Obesity-related comorbidities were resolved in >70% of the patients after surgery. Twelve months after LSG, 25 patients (13.0%) showed a %EWL of <50%; 9 (4.7%) required conversion to gastric bypass due to inadequate weight loss, intolerable reflux symptoms, or intractable diabetes. Conclusion These midterm results show that LSG is a safe and effective surgical procedure for morbidly obese patients. However, a longer follow-up period is necessary to elucidate whether LSG can achieve durable weight loss and long-term outcomes, comparable to those of more aggressive procedures.

Abstract
BACKGROUND Morbidly obese patients display both an autonomic nervous imbalance and impaired glucose metabolism, and both of these conditions can be partially reversed after bariatric surgery. The aim of the present study was to investigate changes in heart rate variability (HRV) and glucose metabolism in patients after laparoscopic sleeve gastrectomy (SG). METHODS Eighteen morbidly obese patients who underwent SG were examined before surgery and at 7, 30, 90, and 180 days after surgery. Indices of HRV included time-domain, frequency-domain, and nonlinear parameters. Glucose metabolism was evaluated by the measuring levels of insulin resistance, glycated hemoglobin (HbA(1c)), and gut hormones. RESULTS The study included 9 men and 9 women with a mean age of 34 years. In the HRV study, the average R-R interval, median R-R interval, standard deviation of the R-R intervals, root mean squared successive difference of the R-R intervals (RMSSD), and the number of pairs of successive normal-to-normal beat intervals that differed by>50 ms significantly increased at 180 days after surgery. Regarding the frequency-domain indices, the low frequency (LF)/high frequency (HF) ratio was more balanced at 90 days after SG compared with baseline, and increases in the total power, LF band, and HF band were observed at 180 days. The assessments of insulin resistance, glucose metabolism, and gut hormones revealed not only improvements in the homeostasis model assessment of insulin resistance and HbA1c levels but also increases in the levels of glucagon-like peptide-1 at 90 and 180 days after surgery compared with baseline. A multivariable regression model revealed significantly negative associations between the perioperative changes in HOMA-IR and changes in both the RMSSD and HF band. CONCLUSIONS SG leads to early improvements in insulin resistance and glucose metabolism that are followed by improvements in HRV indices. Improvements in insulin resistance were associated with increases in the RMSSD and HF band index, but the mechanism of these changes require further study.

Abstract
Bariatric surgery is the most effective therapy to treat obesity and its sequelae. With the increasing incidence of obesity, the number of bariatric procedures has dramatically increased in recent years. The perioperative morbidity reached a very low level, and nearly all revisional bariatric procedures are primarily minimally invasive today. About 10-25% of the patients undergoing bariatric surgery require a revision at some point after their initial operation. Consequently, revisional bariatric surgery has emerged as a distinct practice, performed mainly at tertiary centers, to resolve complications caused by the primary operation and to provide satisfactory weight loss. In this review, our personal experience with revisional bariatric surgery is discussed against the background of the available literature. We further attempt to define major indications for revisional bariatric surgery and balance them with perioperative and long-term morbidity as well as the surgical outcome.
