Abstract
INTRODUCTION Endoscopy prior to bariatric surgery is not always performed, and in sleeve gastrectomy (SG), the surgical specimen is not always sent for pathological examination. There is limited data on the frequency of clinically significant findings in SG specimens or correlation with preoperative endoscopy. METHODS We reviewed 426 consecutive SG patients to determine the concordance of preoperative endoscopy findings in patients with clinically significant postoperative pathology. RESULTS Preoperative endoscopy was performed on 397 patients (93.2%). Three hundred seventy-three patients had preoperative endoscopy and surgical pathology results available. Then, 20/373 (5.4%) patients had potentially significant postoperative pathology, including intestinal metaplasia, autoimmune metaplastic atrophic gastritis (AMAG), gastrointestinal stromal tumors, and/or gastric cancer. The overall incidence of AMAG in the entire cohort was 2.3%. Preoperative gastric biopsies (to include gastric body) identified AMAG in nearly 1/2 of patients. Patients with clinically significant postoperative pathology results had a median [interquartile range] of 3 [3-5] tissue blocks examined as compared to 3 [1-3] for the remainder of the cohort (p < 0.001). CONCLUSION This is one of the largest studies describing clinically significant postoperative pathology after SG. AMAG, in particular, is of particular importance as it is associated with a 3-fivefold increase in risk for gastric cancer. The incidence of significant postoperative pathology in this population is small but potentially clinically significant and requires validation in larger studies. We recommend wider sampling in preoperative endoscopy (body and antrum), especially in patients being planned for gastric bypass, consideration for routine pathological examination of SG surgical specimens, with careful gross examination and targeted sampling.

Abstract
BACKGROUND Whether the benefits of the robotic platform in bariatric surgery translate into superior surgical outcomes remains unclear. The aim of this retrospective study was to establish the 'best possible' outcomes for robotic bariatric surgery and compare them with the established laparoscopic benchmarks. METHODS Benchmark cut-offs were established for consecutive primary robotic bariatric surgery patients of 17 centres across four continents (13 expert centres and 4 learning phase centres) using the 75th percentile of the median outcome values until 90 days after surgery. The benchmark patients had no previous laparotomy, diabetes, sleep apnoea, cardiopathy, renal insufficiency, inflammatory bowel disease, immunosuppression, history of thromboembolic events, BMI greater than 50 kg/m2, or age greater than 65 years. RESULTS A total of 9097 patients were included, who were mainly female (75.5%) and who had a mean(s.d.) age of 44.7(11.5) years and a mean(s.d.) baseline BMI of 44.6(7.7) kg/m2. In expert centres, 13.74% of the 3020 patients who underwent primary robotic Roux-en-Y gastric bypass and 5.9% of the 4078 patients who underwent primary robotic sleeve gastrectomy presented with greater than or equal to one complication within 90 postoperative days. No patient died and 1.1% of patients had adverse events related to the robotic platform. When compared with laparoscopic benchmarks, robotic Roux-en-Y gastric bypass had lower benchmark cut-offs for hospital stay, postoperative bleeding, and marginal ulceration, but the duration of the operation was 42 min longer. For most surgical outcomes, robotic sleeve gastrectomy outperformed laparoscopic sleeve gastrectomy with a comparable duration of the operation. In robotic learning phase centres, outcomes were within the established benchmarks only for low-risk robotic Roux-en-Y gastric bypass. CONCLUSION The newly established benchmarks suggest that robotic bariatric surgery may enhance surgical safety compared with laparoscopic bariatric surgery; however, the duration of the operation for robotic Roux-en-Y gastric bypass is longer.

Abstract
Background and study aims Concomitant hiatal hernia (HH) repair with transoral incisionless fundoplication (TIF) is a therapeutic option for patients with HH > 2 cm and gastroesophageal reflux disease (GERD). Data comparing this approach with laparoscopic Nissen fundoplication (LNF) are lacking. We performed an exploratory analysis to compare these two approaches' adverse events (AEs) and clinical outcomes. Patients and methods This was a multicenter retrospective cohort study of HH repair followed by LNF versus HH repair followed by TIF in patients with GERD and moderate HH (2-5 cm). AEs were assessed using the Clavien-Dindo classification. Symptoms (heartburn/regurgitation, bloating, and dysphagia) were compared at 6 and 12 months. Results A total of 125 patients with HH repair with TIF and 70 with HH repair with LNF were compared. There was no difference in rates of discontinuing or decreasing proton pump inhibitor use, dysphagia, esophagitis, disrupted wrap, and HH recurrence between the two groups ( P > 0.05). The length of hospital stay (1 day vs. 2 days), 30-day readmission rate (0 vs. 4.3 %), early AE rate (0 vs. 18.6 %), and early serious AE rate (0 vs. 4.3 %) favored TIF (all P < 0.05). The rate of new or worse than baseline bloating was lower in the TIF group at 6 months (13.8 % vs. 30.0 %, P = 0.009). Conclusions Concomitant HH repair with TIF is feasible and associated with lower early and serious AEs compared to LNF. Further comparative efficacy studies are warranted.

Abstract
Abstract
Background
Robotic Roux-en-Y gastric bypass (RRYGB) is performed in an increasing number of bariatric centers worldwide. Previous studies have identified a number of demographic and clinical variables as predictors of postoperative complications after laparoscopic Roux-en-Y gastric bypass (LRYGB). Some authors have suggested better early postoperative outcomes after RRYGB compared to LRYGB. The objective of the present study was to assess potential predictors of early postoperative complications after RRYGB.
Methods
A retrospective analysis of two prospective databases containing patients who underwent RRYGB between 2006 and 2019 at two high volumes, accredited bariatric centers was performed. Primary outcome was rate of 30 day postoperative complications. Relevant demographic, clinical and biological variables were entered in a multivariate, logistic regression analysis to identify potential predictors.
Results
Data of 1276 patients were analyzed, including 958 female and 318 male patients. Rates of overall and severe 30 day complications were 12.5% (160/1276) and 3.9% (50/1276), respectively. Rate of 30 day reoperations was 1.6% (21/1276). The overall gastrointestinal leak rate was 0.2% (3/1276). Among various demographic, clinical and biological variables, male sex and ASA score >2 were significantly correlated with an increased risk of 30 day complication rates on multivariate analysis (OR 1.68 and 1.67, p=0.005 and 0.005, respectively).
Conclusion
This study identified male sex and ASA score >2 as independent predictors of early postoperative complications after RRYGB. These data suggest a potentially different risk profile in terms of early postoperative complications after RRYGB compared to LYRGB. The robotic approach might have a benefit for patients traditionally considered to be at higher risk of complications after LRYGB, such as those with BMI >50. The present study was however not designed to assess this hypothesis and larger, prospective studies are necessary to confirm these results.

Abstract
Background The field of bariatric surgery has seen peaks and troughs in the types of metabolic procedures performed. Our primary aim was to evaluate bariatric case volumes among fellows enrolled in bariatric Fellowship Council (FC)-accredited programs. Our secondary aim was to assess trends in revisional case volumes. Methods We reviewed de-identified FC case logs for all bariatric surgery-accredited programs from 2010 through 2019. The number of primary sleeve gastrectomy, gastric band, gastric bypass, biliopancreatic diversion, and major revisional bariatric surgical procedures (defined as a revision with creation of a new anastomosis) were graphed for each academic year. Fellows were stratified into quartiles based on the number of revisional operations per year and graphed over ten years. Volumes of primary gastric bypass, major revisions, and total anastomotic cases were compared over time using ANOVA with p < 0.05 considered significant. Results Case volumes for 822 fellows were evaluated. Sleeve gastrectomy had a significant surge in 2010 and plateaued in 2016. The fellows’ number of primary gastric bypasses had a non-significant decrease from 84 to 75 cases/fellow from 2010 to 2019. This decrease was offset by a significant increase in major revisional surgery from 8 to 19 cases/fellow. As a result, the number of anastomotic cases did not change significantly over the study time period. Interestingly, as revisional volume has grown, the gap between quartiles of fellowship programs has widened with the 95th percentile growing at a much faster rate than lower quartiles. Conclusion The volume of bariatric procedures performed in the last decade among FC fellows follows similar trends to national data. Major revisional cases have doubled with the most robust growth isolated to a small number of programs. As revisional surgery continues to increase, applicants interested in a comprehensive bariatric practice should seek out training programs that offer strong revisional experience.

Abstract
BACKGROUND Endoscopic sleeve gastroplasty (ESG) is an endolumenal, organ-sparing therapy for obesity, with wide global adoption. We aimed to explore the efficacy and safety of ESG with lifestyle modifications compared with lifestyle modifications alone. METHODS We conducted a randomised clinical trial at nine US centres, enrolling individuals aged 21-65 years with class 1 or class 2 obesity and who agreed to comply with lifelong dietary restrictions. Participants were randomly assigned (1:1·5; with stratified permuted blocks) to ESG with lifestyle modifications (ESG group) or lifestyle modifications alone (control group), with potential retightening or crossover to ESG, respectively, at 52 weeks. Lifestyle modifications included a low-calorie diet and physical activity. Participants in the primary ESG group were followed up for 104 weeks. The primary endpoint at 52 weeks was the percentage of excess weight loss (EWL), with excess weight being that over the ideal weight for a BMI of 25 kg/m2. Secondary endpoints included change in metabolic comorbidities between the groups. We used multiple imputed intention-to-treat analyses with mixed-effects models. Our analyses were done on a per-protocol basis and a modified intention-to-treat basis. The safety population was defined as all participants who underwent ESG (both primary and crossover ESG) up to 52 weeks. FINDINGS Between Dec 20, 2017, and June 14, 2019, 209 participants were randomly assigned to ESG (n=85) or to control (n=124). At 52 weeks, the primary endpoint of mean percentage of EWL was 49·2% (SD 32·0) for the ESG group and 3·2% (18·6) for the control group (p<0·0001). Mean percentage of total bodyweight loss was 13·6% (8·0) for the ESG group and 0·8% (5·0) for the control group (p<0·0001), and 59 (77%) of 77 participants in the ESG group reached 25% or more of EWL at 52 weeks compared with 13 (12%) of 110 in the control group (p<0·0001). At 52 weeks, 41 (80%) of 51 participants in the ESG group had an improvement in one or more metabolic comorbidities, whereas six (12%) worsened, compared with the control group in which 28 (45%) of 62 participants had similar improvement, whereas 31 (50%) worsened. At 104 weeks, 41 (68%) of 60 participants in the ESG group maintained 25% or more of EWL. ESG-related serious adverse events occurred in three (2%) of 131 participants, without mortality or need for intensive care or surgery. INTERPRETATION ESG is a safe intervention that resulted in significant weight loss, maintained at 104 weeks, with important improvements in metabolic comorbidities. ESG should be considered as a synergistic weight loss intervention for patients with class 1 or class 2 obesity. This trial is registered with ClinicalTrials.gov, NCT03406975.

Abstract
BACKGROUND Gastric outlet obstruction secondary to foregut gastrointestinal malignancies can be managed with a variety of medical, endoscopic, and surgical options. Laparoscopic gastrojejunostomy is an option for those patients who are able to tolerate an operation as a long-term palliative option. This operation may be associated with some significant postoperative technical and nontechnical complications, including delayed gastric emptying. This paper describes an incision-less, endoscopic option that we propose can be used to salvage a functionally obstructed gastrojejunostomy. CASE DESCRIPTION A 57-year old male patient had a history of pancreatic adenocarcinoma causing gastric outlet obstruction and underwent a previously created surgical gastrojejunostomy at an outside hospital. His procedure was complicated by anastomotic leak and essentially persistent obstructive symptoms secondary to delayed gastric emptying. Though his anastomosis was demonstrably patent, these symptoms were thought to be secondary to a functional obstruction at the gastrojejunostomy. After repeated workups and many failed attempts to treat these symptoms, he ultimately underwent endoscopic placement of an uncovered colonic stent into the efferent limb of his gastrojejunostomy. This allowed for preferential drainage of gastric contents down the efferent limb, and improvement of his delayed gastric emptying. CONCLUSIONS In a select group of patients with advanced foregut malignancy, and with high re-operative risks, salvage endoscopic stenting may be useful in the palliation of symptoms from a functionally obstructed gastrojejunostomy.

Abstract
INTRODUCTION/PURPOSE Some clinical indicators suggest hypercoagulability/hyperaggregability in patients with morbid obesity. Thromboelastography (TEG®) has been used to profile coagulation status in surgical patients. We aimed to assess coagulation profiles in patients with morbid obesity undergoing bariatric surgery by correlating demographic and patient characteristics to pre-operative TEG® values. MATERIALS AND METHODS Pre-operative TEG® values from 422 patients undergoing bariatric surgery were evaluated. TEG® results were analyzed by gender, use of medications known to alter the coagulation profile, and body mass index (BMI). RESULTS Patients have a mean of 45.03 ± 11.8 years, female (76.3%), and with a mean BMI of 42 kg/m 1. The overall coagulation profile of female patients was significantly different from males, even in the sub-cohort without use of medications known to alter coagulation. The majority of patients (94%) with a G value > 15 dynes/cm 1 (clot strength) were female. In females, there was no association between BMI and TEG® values; however, in men, there was a statistically significant difference in TEG® values for those with BMI < 40 kg/m 1 compared to those with BMI > 50 kg/m2. CONCLUSIONS TEG®-based analysis of coagulation profiles offers unique insights. Compared to laboratory normal values (R time, angle, maximal amplitude, and G values), patients with morbid obesity may have a tendency for hypercoagulability/hyperaggregability, with mean values at the higher limit. A significant hypercoagulable difference in TEG® values was identified in female as compared to male patients. Male patients with a BMI greater than 50 kg/m2 were also found to be increasingly hypercoagulable.

Abstract
Background Postoperative morbidity after laparoscopic bariatric surgery is considered higher for patients undergoing revisional versus primary procedures. The objective of this retrospective cohort study was to compare outcomes between patients undergoing primary versus revisional robotically assisted laparoscopic (RAL) Roux-en-Y gastric bypass (RYGB). Methods Data of all patients who underwent RAL primary and revisional RYGB between 2009 and 2019 at two accredited, high-volume bariatric surgery centers—the Memorial Hermann – Texas Medical Center, Houston, TX, and the Tower Health, Reading Hospital, Reading, PA, were analyzed. Primary outcomes were early (< 30 days) and overall postoperative complications. Secondary outcomes included intraoperative complications, operative times, conversions to laparotomy, length of hospital stay, early (< 30 days) postoperative readmissions and deaths. Results Data of 1072 patients were analyzed, including 806 primary and 266 revisional RAL RYGB procedures. Longer operative times (203 versus 154 min, P < 0.001), increased number of readmissions for oral intolerance (10.5% versus 6.7%, P = 0.046) and higher rate of gastrojejunal stricture (6.4% versus 2.7%, P = 0.013) were found in the revisional group. Gastrointestinal leak rates were 0.2% for the primary versus 1.1% for the revisional group (P = 0.101). Early (< 30 days) reoperations rates were 2.2% for the primary versus 1.1% for the revisional group (P = 0.318). There were no statistically significant differences between groups in overall and severe complication rates. Conclusion Patients undergoing RAL primary and revisional RYGB had comparable overall outcomes, with a non-significant higher early complication rate in the revisional group. Despite the study being underpowered to detect differences in specific complication rates, the morbidity seen in the revisional RYGB group remains markedly below literature reports of revisional laparoscopic RYGB and might suggest a benefit of robotic assistance. Further prospective studies are needed to confirm these results.

Abstract
BACKGROUND Laparoscopic repair of recurrent as opposed to primary paraesophageal hernias (PEHs) are historically associated with increased peri-operative complication rates, worsened outcomes, and increased conversion rates. The robotic platform may aid surgeons in these complex revision procedures. The aim of this study was to compare the outcomes of patients undergoing robotic assisted laparoscopic (RAL) repair of recurrent as opposed to primary PEHs. METHODS Patients undergoing RAL primary and recurrent PEH repairs from 2009 to 2017 at a single institution were reviewed. Demographics, use of mesh, estimated blood loss, intra-operative complications, conversion rates, operative time, rates of esophageal/gastric injury, hospital length of stay, re-admission/re-operation rates, recurrence, dysphagia, gas bloat, and pre- and post-operative proton pump inhibitor (PPI) use were analyzed. Analysis was accomplished using Chi-square test/Fischer's exact test for categorical variables and the Mann-Whitney U test for continuous variables. RESULTS There were 298 patients who underwent RAL PEH repairs (247 primary, 51 recurrent). They were followed for a median (interquartile range) of 120 (44, 470) days. There were no significant differences in baseline demographics between groups. Patients in the recurrent PEH group had longer operative times, increased use of mesh, and increased length of hospital stay. They were also less likely to undergo fundoplication. There were no significant differences in estimated blood loss, incidence of intra-operative complications, re-admission rates, incidence of post-operative dysphagia and gas bloat, and incidence of post-operative PPI use. There were no conversions to open operative intervention or gastric/esophageal injury/leaks. CONCLUSIONS Although repair of recurrent PEHs are historically associated with worse outcomes, in this series, RAL recurrent PEH repairs have similar peri-operative and post-operative outcomes as compared to primary PEH repairs. Whether this is secondary to the potential advantages afforded by the robotic platform deserves further study.

Abstract
After careful review, the authors have noticed the following mistakes in the article entitled "Trocar site closure with a novel anchor based (neoClose®) system versus standard suture closure: A prospective randomized controlled trial": - Correct closure times are 19.9 seconds (SD 9.9) for the study group and 31.0 seconds (SD 20.1) for the control group (initial incorrect values were 20.2 seconds (SD 10.1) and 30 seconds (SD 19.1) respectively). The new correct P-value is <0.0001 (initial incorrect P-value was 0.0002). - Correct maximal needle depth values are 3.2 cm (SD 0.93) for the study group and 4.9 cm (SD 1.97) for the control group (initial incorrect values were 3.3 cm (SD 0.9) and 5.2 cm (SD 1.6) respectively). P-value remains unchanged at <0.0001. For these two outcomes, some values of control group patients were mistakenly included in the study group. These errors only marginally affected the mean and standard deviation values. Statistical significance of the results was not affected and the conclusions of the study remain unchanged.

Abstract
BACKGROUND The Orbera intragastric balloon (IGB) has been approved by the US Food and Drug Administration for use in patients with a body mass index (BMI) between 30 and 40 kg/m2 and is in wide use worldwide as a primary and bridge obesity management tool. The balloon filling volume (BFV) ranges between 400 and 700 mL of saline. Our objective was to determine whether there is an association between BFV and clinically relevant endpoints, namely weight loss outcomes, balloon tolerability, and adverse events. METHODS A systematic review of studies investigating the use of the Orbera IGB system for obesity treatment was performed. Data was examined using random effects modelling and meta-regression analyses. RESULTS Forty-four studies (n = 5549 patients) reported BFV and % total body weight loss (TBWL) at 6 months. Pooled %TBWL at 6 months was 13.2% [95% CI 12.3-14.0]. A funnel plot demonstrated a low risk of publication bias. Meta-regression showed no statistically significant association between filling volume and %TBWL at 6 months (p = 0.268). Higher BFV was associated with lower rates of esophagitis (slope = -0.008, p < 0.001) and prosthesis migration (slope = -0.015, p < 0.001). There was no association between BFV and early removal (p = 0.1), gastroesophageal reflux symptom (p = 0.64), or ulcer rates (p = 0.09). CONCLUSIONS No association was observed between Orbera IGB filling volume and weight loss outcomes. Higher volumes appear to be associated with lower migration and esophagitis rates; thus, a balloon filling volume of 600-650 mL is recommended.

Abstract
BACKGROUND The utilization of robotic platforms for general surgery procedures such as hernia repair is growing rapidly in the United States. A limited amount of data are available evaluating operative outcomes in comparison to standard laparoscopic surgery. We completed a retrospective review comparing robotic and laparoscopic ventral hernia repair to provide safety and outcomes data to help design a future prospective trial design. METHODS A retrospective review of 215 patients undergoing ventral hernia repair (142 robotic and 73 laparoscopic) was completed at two large academic centers. Primary outcome measure evaluated was recurrence. Secondary outcomes included incidence of primary fascial closure, and surgical site occurrences. RESULTS Propensity for treatment match comparison demonstrated that robotic repair was associated with a decreased incidence of recurrence (2.1 versus 4.2%, p < 0.001) and surgical site occurrence (4.2 versus 18.8%, p < 0.001). This may be because robotic repair was associated with increased incidence of primary fascial closure (77.1 versus 66.7%, p < 0.01). Analysis of baseline patient populations showed that robotic repairs were completed on patients with lower body mass index (28.1 ± 3.6 versus 34.2 ± 6.4, p < 0.001) and fewer comorbidities. CONCLUSIONS Our retrospective data show that robotic repair was associated with decreased recurrence and surgical site occurrence. However, the differences noted in the patient populations limit the interpretability of these results. As adoption of robotic ventral hernia repair increases, prospective trials need to be designed in order to investigate the efficacy, safety, and cost effectiveness of this evolving technique.

Abstract
BACKGROUND AND AIMS Many patients who undergo bariatric surgery will experience weight regain and effective strategies are needed to help these patients. A dilated gastrojejunal anastomosis (GJA) has been associated with weight recidivism after Roux-en-Y gastric bypass surgery (RYGB). Endoscopic transoral outlet reduction (TORe) with a full thickness endoscopic suturing device (Overstitch, Apollo Endosurgery, Austin, TX) is a minimally invasive therapeutic option. The primary aim of this project was to examine the safety and long-term efficacy data from three bariatric surgery centers and to conduct a systematic review and meta-analysis of the existing literature. METHODS Patients who underwent TORe with the Overstitch device from Jan 2013 to Nov 2016 at 3 participating bariatric surgery centers were included in the multicenter analysis. For the systematic review and meta-analysis, a comprehensive search of multiple English databases was conducted. Random effects model was used. RESULTS 130 consecutive patients across three centers underwent TORe with an endolumenal suturing device. These patients (mean age 47; mean BMI 36.8) had experienced 24.6% weight regain from nadir weight after RYGB. Average weight lost at 6, 12, and 18 months after TORe was 9.31 ± 6.7 kg (N = 84), 7.75 ± 8.4 kg (N = 70), 8 ± 8.8 kg (N = 46) (p < 0.01 for all three time points), respectively. The meta-analysis included 330 patients. The pooled weight lost at 12 months was 8.4 kg (95% CI 6.5-10.3) with no significant heterogeneity across included studies (p = 0.07). Overall, 14% of patients experienced nausea, 18% had pain and 8% required a repeat EGD. No serious adverse events reported. CONCLUSION When implemented as part of a multidisciplinary intervention, TORe using endolumenal suturing is safe, reproducible, and effective approach to manage weight recidivism after RYGB and should be utilized early in the management algorithm of these patients.

Abstract
AbstractComplications of the laparoscopic adjustable gastric band, including erosion, have been well described. Increasingly, endoscopic techniques are being utilized to manage complications of this and other weight loss procedures. The authors presented what was believed to be one of the first reported cases of successful endoscopic removal of an eroded gastric band during pregnancy. A complete description of the case and review of the relevant literature is provided. Endoscopy for management of eroded adjustable gastric bands needs to be part of the armamentarium of surgeons and endoscopists who deal with complications of weight loss surgery.

Abstract
Human natural killer (NK) cells play an important role in anti-viral immunity. However, studying their activation kinetics during infection is highly problematic. A clinical trial of a therapeutic virus provided an opportunity to study human NK cell activation in vivo in a controlled manner. Ten colorectal cancer patients with liver metastases received between one and five doses of oncolytic reovirus prior to surgical resection of their tumour. NK cell surface expression of the interferon-inducible molecules CD69 and tetherin peaked 24-48 h post-infection, coincident with a peak of interferon-induced gene expression. The interferon response and NK cell activation were transient, declining by 96 h post-infection. Furthermore, neither NK cell activation nor the interferon response were sustained in patients undergoing multiple rounds of virus treatment. These results show that reovirus modulates human NK cell activity in vivo and suggest that this may contribute to any therapeutic effect of this oncolytic virus. Detection of a single, transient peak of activation, despite multiple treatment rounds, has implications for the design of reovirus-based therapy. Furthermore, our results suggest the existence of a post-infection refractory period when the interferon response and NK cell activation are blunted. This refractory period has been observed previously in animal models and may underlie the enhanced susceptibility to secondary infections that is seen following viral infection.

Abstract
INTRODUCTION The growth of bariatric surgery has resulted in varying types of procedures with increasing complexity. Robotic digital platforms are employed in bariatric surgery to address this increasing complexity in the high-risk obese patient population with difficult anatomy. MATERIALS AND METHODS This review explores the literature and examines the reported outcomes and complications in using robotics for bariatric surgery. Robotic approaches to adjustable gastric banding, sleeve gastrectomy, gastric bypass, and biliopancreatic diversion with duodenal switch are examined. Revisional cases, learning curves, and cost effectiveness are reviewed, with an eye toward the future of bariatric surgery as the use of robotics is adopted. CONCLUSION Digital platforms are showing great promise as enabling technology which advance bariatric outcomes. With increasingly complex bariatric cases being performed and revised, the insertion of digital information between the surgeon and the patient leads to better operations for the patient and the surgeon.

Abstract
BACKGROUND & AIMS Transoral esophagogastric fundoplication (TF) can decrease or eliminate features of gastroesophageal reflux disease (GERD) in some patients whose symptoms persist despite proton pump inhibitor (PPI) therapy. We performed a prospective, sham-controlled trial to determine if TF reduced troublesome regurgitation to a greater extent than PPIs in patients with GERD. METHODS We screened 696 patients with troublesome regurgitation despite daily PPI use with 3 validated GERD-specific symptom scales, on and off PPIs. Those with at least troublesome regurgitation (based on the Montreal definition) on PPIs underwent barium swallow, esophagogastroduodenoscopy, 48-hour esophageal pH monitoring (off PPIs), and high-resolution esophageal manometry analyses. Patients with GERD and hiatal hernias ≤2 cm were randomly assigned to groups that underwent TF and then received 6 months of placebo (n = 87), or sham surgery and 6 months of once- or twice-daily omeprazole (controls, n = 42). Patients were blinded to therapy during follow-up period and reassessed at 2, 12, and 26 weeks. At 6 months, patients underwent 48-hour esophageal pH monitoring and esophagogastroduodenoscopy. RESULTS By intention-to-treat analysis, TF eliminated troublesome regurgitation in a larger proportion of patients (67%) than PPIs (45%) (P = .023). A larger proportion of controls had no response at 3 months (36%) than subjects that received TF (11%; P = .004). Control of esophageal pH improved after TF (mean 9.3% before and 6.3% after; P < .001), but not after sham surgery (mean 8.6% before and 8.9% after). Subjects from both groups who completed the protocol had similar reductions in GERD symptom scores. Severe complications were rare (3 subjects receiving TF and 1 receiving the sham surgery). CONCLUSIONS TF was an effective treatment for patients with GERD symptoms, particularly in those with persistent regurgitation despite PPI therapy, based on evaluation 6 months after the procedure. Clinicaltrials.gov no: NCT01136980.

Abstract
OBJECTIVE To report our results from series of robotic-assisted laparoscopic augmentation enterocystoplasty (RALAE) performed in a completely intracorporeal fashion. METHODS Patients who underwent RALAE with or without the creation of a catheterizable channel between 2006 and 2011 at the University of Texas, Houston and Northwestern Memorial Hospital were identified. Perioperative and follow-up data were analyzed. Preoperative and postoperative urodynamic data were analyzed when available. RESULTS Twenty-two patients with neurogenic bladder underwent RALAE with or without the creation of a catheterizable channel. Fifteen patients underwent robotic augmentation enterocystoplasty alone, and 7 patients had creation of a catheterizable channel (4 Monti and 3 Mitrofanoff). There was 1 conversion to an open procedure in a patient undergoing concomitant creation of an appendicovesicostomy. Mean follow-up was 38.9 months (range, 6.2-72.1 months). Mean operative time was 365 minutes (range, 220-788 minutes); mean estimated blood loss was 110 mL (range, 30-250 mL). Median time to return of bowel function was 5 days (range, 2-17 days). Preoperative and postoperative urodynamic data were available for 13 patients. Mean cystometric capacity increased by 52%, and mean maximal bladder pressures decreased by 40. There were 5 minor complications (Clavien grade 1-2) and 4 major complications (Clavien grade 3-4). No patient experienced a wound infection. CONCLUSION RALAE is a feasible approach that provides potential benefits over open bladder reconstruction in the neurogenic voiding dysfunction population.

Abstract
BACKGROUND In 2008, the Realize Band (RB) adopted a precurved design (RB-C). We present 2-year outcomes data from the first multiinstitutional study of RB-C. The objective of this study was to analyze weight loss and safety data from bariatric practices in the United States, including academic, nonacademic, public, and private. METHODS The study included adult RB-C patients with a preoperative body mass index (BMI)≥40 kg/m(2) or >35 kg/m(2) with co-morbidity. Exclusions included RB-C's label contraindications for use. Outcomes parameters were percent excess weight loss (%EWL), BMI change, number and volume of band adjustments, and adverse events. RESULTS A total of 231 patients met inclusion/exclusion criteria. Of these, 161 had 24-month data available. Mean %EWL was 44.4%±26.9% (P<.0001). BMI decreased from 44.1±5.7 kg/m(2) to 35.3±6.9 kg/m(2) (P<.0001). Percent EWL varied by preoperative BMI (P = .0002), bariatric practice (P<.0001), aftercare frequency (P = .0004), and band fill frequency (P = .0271), but %EWL was not influenced by gender, race, or age (P>.20 each). Adverse events were dysphagia (21.2%), gastroesophageal reflux (21.6%), and vomiting (30.7%). Incidence of pouch dilation, esophageal dilation, and slippage was ≤1%. Revisions (2.2%) were for unbuckled band, tube kinking, slippage, and suspected band leak (1 each). No erosions, explants, or mortality were reported. CONCLUSION RB-C appears to be as well tolerated and effective as the first generation RB for weight loss. The near 45% EWL at 2 years is consistent with other high-quality publications on the RB. Preoperative BMI and frequency of postoperative care, including frequency of band fills, influence %EWL. Significant weight loss is achievable with RB-C despite variable postoperative management practices. The low morbidity and the absence of mortality at 24 months reflect positively on the RB-C characteristics.

Abstract
BACKGROUND Obesity is a systemic disorder associated with an increase in left ventricular mass and premature death and disability from cardiovascular disease. Although bariatric surgery reverses many of the hormonal and hemodynamic derangements, the long-term collective effects on body composition and left ventricular mass have not been considered before. We hypothesized that the decrease in fat mass and lean mass after weight loss surgery is associated with a decrease in left ventricular mass. METHODS Fifteen severely obese women (mean body mass index [BMI]: 46.7+/-1.7 kg/m(2)) with medically controlled hypertension underwent bariatric surgery. Left ventricular mass and plasma markers of systemic metabolism, together with body mass index (BMI), waist and hip circumferences, body composition (fat mass and lean mass), and resting energy expenditure were measured at 0, 3, 9, 12, and 24 months. RESULTS Left ventricular mass continued to decrease linearly over the entire period of observation, while rates of weight loss, loss of lean mass, loss of fat mass, and resting energy expenditure all plateaued at 9 [corrected] months (P <.001 for all). Parameters of systemic metabolism normalized by 9 months, and showed no further change at 24 months after surgery. CONCLUSIONS Even though parameters of obesity, including BMI and body composition, plateau, the benefits of bariatric surgery on systemic metabolism and left ventricular mass are sustained. We propose that the progressive decrease of left ventricular mass after weight loss surgery is regulated by neurohumoral factors, and may contribute to improved long-term survival.

Abstract
Surgical robotics in general surgery has a relatively short but very interesting evolution. Just as minimally invasive and laparoscopic techniques have radically changed general surgery and fractionated it into subspecialization, robotic technology is likely to repeat the process of fractionation even further. Though it appears that robotics is growing more quickly in other specialties, the changes digital platforms are causing in the general surgical arena are likely to permanently alter general surgery. This review examines the evolution of robotics in minimally invasive general surgery looking forward to a time where robotics platforms will be fundamental to elective general surgery. Learning curves and adoption techniques are explored. Foregut, hepatobiliary, endocrine, colorectal, and bariatric surgery will be examined as growth areas for robotics, as well as revealing the current uses of this technology.

Abstract
BACKGROUND Despite the rapid acceptance of laparoscopic Roux-en-Y gastric bypass (RYGB) by the community and increase in the number of these procedures being done, there is still significant morbidity and mortality. METHODS At the University of Texas Medical School at Houston, we have performed 320 RYGB with robotic assistance (RARYGB). Surgical times, length of stay, morbidity, and mortality have been recorded since the beginning of our robotic experience and represent the world's largest single institution series of RARYGB. Outcome data were examined in a postoperative cohort. RESULTS The average starting BMI was 49.1 kg/m(2), and it declined by 66% to 32.5 kg/m(2) by the end of 1 year. The average operative time was 192 min, and the average length of stay was 2.7 days. Within the first year, there were a total of 77 (24.1%) complications. The foremost complications noted in the literature to be 3% to 11% were all <1% in our series, and we have no mortalities. Compared to our 356 laparoscopic RYGB, there was a significantly lower gastrointestinal leak rate in the robotic arm. A cohort of 79 postoperative patients was analyzed with respect to weight loss, resolution of co-morbidity, and quality of life. While there was no variation in quality of life over time, weight loss, resolution of co-morbidities, and overall outcome score were significantly improved. CONCLUSIONS We effectively perform robotic-assisted RYGB that lowers the morbidity and mortality of this procedure compared to today's standard while maintaining thriving outcomes.

Abstract
BACKGROUND While the majority of patients achieve good outcomes with the LAP-BAND, there is a subset of patients who experience complications or fail to lose sufficient weight after the banding procedure. This study examines the feasibility and outcome of performing laparoscopic Roux-en-Y gastric bypass (RYGBP) as a single-step revision surgery after a failed LAP-BAND procedure. METHODS In the past five years we have performed more than 1400 LAP-BAND procedures. We laparoscopically converted 33 (30 females) of these patients (mean age = 43.8 years) from LAP-BAND to RYGBP because of inadequate weight loss and/or complications. Key steps in the revision procedures were (1) identification and release of the band capsule; (2) careful dissection of the gastrogastric sutures; (3) creation of a small gastric pouch; and (4) Roux-en-Y anterior colic anterior gastric pouch-jejunum anastomosis. Revisions took place at a mean 28.2 months (range = 11-46; SD = 11.3) after the original gastric banding. Change in body mass index (BMI) between pre- and postrevision was evaluated with paired t tests. RESULTS Among the 33 patients who would undergo revision surgery, the mean BMI before the LAP-BAND procedure was 45.7 kg/m2 (range = 39.9-53.0; SD = 3.4) and the mean weight was 126 kg (range = 99-155; SD = 17). The lowest BMI achieved by this group with the LAP-BAND before revision was 39.7 kg/m2 (range = 30-49.2; SD = 4.9); however, the mean BMI at the time of revision was 42.8 kg/m2 (range = 33.1-50; SD = 4.8). The mean revision operative time was 105 min (range = 85-175), and the mean hospital stay was 2.8 days (range = 1-10). Complications included one patient who underwent open reoperation and splenectomy for a bleeding spleen and one patient who required repair of an internal hernia. After conversion to RYGBP, mean BMI decreased to 33.9 kg/m2 at 6 months (p < 0.001) and 30.7 kg/m2 (range = 22-39.6; SD = 5.3) at 12 months or more of followup (average = 15.7 months; p < 0.0001). CONCLUSIONS Laparoscopic conversion from LAP-BAND to RYGBP is safe and can be an alternative for patients who failed the LAP-BAND procedure. However, revision surgery is technically challenging and should be performed only by surgeons who have completed the learning curve for laparoscopic RYGBP.

Abstract
BACKGROUND Several lines of evidence have suggested a link between obesity and heart failure, including chronic inflammation, increased sympathetic tone, and insulin resistance. The goal of this study was to evaluate the changes in systemic metabolism, anthropometrics, and left ventricular (LV) contraction, as well as geometry, in clinically severe obese women after bariatric surgery. METHODS Enrollment was offered consecutively to 22 women with clinically severe obesity. Participants underwent abdominal magnetic resonance imaging to quantify the visceral adipose tissue (VAT) area and tissue Doppler imaging echocardiography to measure the LV contractile function. Fasting blood chemistries were drawn to measure inflammatory markers and to calculate insulin sensitivity. All tests were performed before surgery and 3 months postoperatively. RESULTS Three months after surgery, a significant increase in insulin sensitivity (mean change +/- SEM 34.0 +/- 10.4, P < .0001) was present. The VAT area had significantly decreased (-66.1 +/- 17.8 cm2, P = .002) and was associated with decreases in body mass index, serum glucose concentrations, and high-sensitivity C-reactive protein levels (r = .61 and P = .005, r = .48 and P = .033, and r = .53 and P = .016, respectively). The LV mass decreased significantly (-3.8 +/- 1.7 g/m(2.7), P = .037), and this decrease was associated with a decrease in glucose concentration (r = .46, P = .041). The LV systolic and diastolic contractile function were normal at baseline, and no change occurred after surgery. CONCLUSION The early phase of weight loss after bariatric surgery produces favorable changes in LV geometry, and these are associated with normalization in the glucose metabolism.
