Chow A, Neville A, Kolozsvari N. Smoking in bariatric surgery: a systematic review. Surg Endosc 2021; 35:3047-3066. [PMID: 32524412 DOI: 10.1007/s00464-020-07669-3] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2020] [Accepted: 05/20/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND The prevalence of smoking among patients undergoing bariatric surgery has been reported to be as high as 40%. The effect of smoking in the perioperative period has been extensively studied for various surgical procedures, but limited data are available for bariatric surgery. The objective of this study is to review the existing literature to assess: (1) the impact of smoking on postoperative morbidity and mortality after bariatric surgery, (2) the relationship between smoking and weight loss after bariatric surgery, and (3) the efficacy of smoking cessation in the perioperative period among bariatric surgery patients. METHODS A comprehensive search of electronic databases including MEDLINE, EMBASE and the Cochrane Library from 1946 to February 2020 was performed to identify relevant articles. Following an initial screen of 940 titles and abstracts, 540 full articles were reviewed. RESULTS Forty-eight studies met criteria for analysis: five structured interviews, three longitudinal studies, thirty-two retrospective studies and eight prospective studies. Smoking within 1 year prior to bariatric surgery was found to be an independent risk factor for increased 30-day mortality and major postoperative complications, particularly wound and pulmonary complications. Smoking was significantly associated with long-term complications including marginal ulceration and bone fracture. Smoking has little to no effect on weight loss following bariatric surgery, with studies reporting at most a 3% increased percentage excess weight loss. Rates of smoking recidivism are high with studies reporting that up to 17% of patients continue to smoke postoperatively. CONCLUSIONS Although current best practice guidelines recommend only a minimum of 6 weeks of abstinence from smoking prior to bariatric surgery, the findings of this review suggest that smoking within 1 year prior to bariatric surgery is associated with significant postoperative morbidity. More investigation is needed on strategies to improve smoking cessation compliance among bariatric surgery patients in the perioperative period.

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.

Lo HC, Wu SM. Reappraisal learning curve of laparoscopic Roux-en Y gastric bypass: retrospective results of one hundred and eight cases from a low-volume unit. BMC Surg 2021; 21:86. [PMID: 33588802 PMCID: PMC7885431 DOI: 10.1186/s12893-021-01058-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2020] [Accepted: 01/12/2021] [Indexed: 11/30/2022] Open
Abstract
Background This study aimed to reevaluate the learning curve of laparoscopic Roux-en Y gastric bypass (LRYGB) in the modern era while considering a single surgeon’s experience. Methods From the beginning of our LRYGB practice, all patients who met the regional criteria and underwent primary LRYGB were retrospectively enrolled. Patients with a body mass index (BMI) > 50 kg/m2 were excluded. Those who underwent surgery in 2016–17, 2018 and 2019 by a single surgeon with 10 + years of laparoscopic experience were assigned to groups A, B and C, respectively. The patient demographics and 30-day outcome data, including the operation time, length of stay (LOS), emergency room visits, readmission, and reoperation, were compared among the groups. Results One hundred and eight patients met the inclusion criteria; 36, 38, and 34 patients were assigned to groups A, B and C, respectively. There were no differences in age, sex distribution or common comorbidities among the groups; however, B had a lower BMI (35.1 kg/m2 vs. 37.0 kg/m2) and a higher rate of hypertension (44.7% vs. 22.2%) than group A. The operation time was markedly reduced (96.1 min and 114.9 min, p < 0.001), and the LOS was shortened (2.2 days and 2.9 days, p < 0.001) in group B compared to group A and remained stationary in group C, with no further reduction in 30-day complications. Conclusion The learning process of LRYGB can be shortened to approximately 30 cases if conducted selectively by experienced laparoscopic surgeons. Further follow-up is required to verify the long-term safety and applicability in other patient subgroups.

Variables Associated with Short-Term Weight Loss in a Cohort of Patients with Morbid Obesity According to Age and Three Types of Bariatric Surgery. J Clin Med 2020; 9:jcm9113537. [PMID: 33147793 PMCID: PMC7692348 DOI: 10.3390/jcm9113537] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2020] [Revised: 10/28/2020] [Accepted: 10/29/2020] [Indexed: 11/26/2022] Open
Abstract
Background The percentage of excess weight lost (%EWL) after bariatric surgery (BS) shows great discrepancies from one individual to another. Objective To evaluate the %EWL one year after BS and to determine the existence of baseline biomarkers associated with weight loss. Methods We studied 329 patients with morbid obesity undergoing three types of BS (biliopancreatic diversion (BPD), Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG)), depending on the %EWL one year after surgery: good responders (GR) (%EWL ≥ 50%) and non-responders (NR) (%EWL < 50%). Results The GR presented a higher percentage of change in anthropometric and biochemical variables compared to the NR group, even within each type of BS. There was a greater percentage of GR among those who underwent RYGB. The patients who underwent SG showed the lowest decrease in biochemical variables, both in GR and NR. Within the GR group, those with a lower age showed greater improvement compared to the other age groups. A %EWL ≥50% was negatively associated with the age and atherogenic index of plasma (AIP), and positively with the type of BS (RYGB). Conclusions The GR group was associated with lower age and AIP and undergoing RYGB. Additionally, those patients who underwent SG showed a lower metabolic improvement.

Abstract
OBJECTIVE To develop and evaluate a novel instrument to measure SEVERE processes using video data. BACKGROUND Surgical video data can serve an important role in understanding the relationship between intraoperative events and postoperative outcomes. However, a standard tool to measure severity of intraoperative events is not yet available. METHODS Items to be included in the instrument were identified through literature and video reviews. A committee of experts guided item reduction, including pilot tests and revisions, and determined weighted scores. Content validity was evaluated using a validated sensibility questionnaire. Inter-rater reliability was assessed by calculating intraclass correlation coefficient. Construct validity was evaluated on a sample of 120 patients who underwent laparoscopic Roux-en-Y gastric bypass procedure, in which comprehensive video data was obtained. RESULTS SEVERE index measures severity of 5 event types using ordinal scales. Each intraoperative event is given a weighted score out of 10. Inter-rater reliability was excellent [0.87 (95%-confidence interval, 0.77-0.92)]. In a sample of consecutive 120 patients undergoing gastric bypass procedures, a median of 12 events [interquartile range (IQR) 9-18] occurred per patient and bleeding was the most frequent type (median 10, IQR 7-14). The median SEVERE score per case was 11.3 (IQR 8.3-16.9). In risk-adjusted multivariable regression models, history of previous abdominal surgery (P = 0.02) and body mass index (P = 0.005) were associated with SEVERE scores, demonstrating construct validity evidence. CONCLUSION The SEVERE index may prove to be a useful instrument in identifying patients with high risk of developing postoperative complications.

Abstract
OBJECTIVE To describe a case of a male adolescent with symptomatic idiopathic intracranial hypertension (IIH) associated with obesity treated with bariatric surgery. CASE DESCRIPTION A 16-year-and-6-month-old severely obese boy [weight: 133.6 kg; height: 1.74 m (Z score: +0.14); BMI: 44.1 kg/m2 (Z score: +4.4)], Tanner pubertal stage 5, presented biparietal, high-intensity, and pulsatile headaches, about five times per week, associated with nocturnal awakenings, and partial improvement with common analgesics, for three months. Ophthalmologic evaluation evidenced bilateral papilledema. Cranial computed tomography revealed no mass or anatomic abnormalities. Lumbar puncture showed increased intracranial pressure of 40 cmH2O (reference value: <28 cmH2O) with a normal content. After being diagnosed with IIH, the patient was started on acetazolamide. However, after three months, he was still symptomatic. He was diagnosed with obesity due to excess energy intake and, as he had failed to lose weight after a conventional clinical treatment, bariatric surgery was indicated. The patient (at 16 years and nine months) underwent an uncomplicated laparoscopic sleeve gastrectomy. Ophthalmologic evaluation, performed five months after surgery, revealed normal visual acuity in both eyes and improvement of bilateral papilledema. Follow-up at 18 months showed a 67.5% loss of excess weight (weight: 94.5 kg and BMI: 31.2 kg/m2) and complete resolution of IIH symptoms. COMMENTS IIH is characterized by increased intracranial pressure with no evidence of deformity or obstruction of the ventricular system on neuroimaging. It has been associated with obesity. Bariatric surgery may be a valid alternative approach for morbidly obese adolescent patients with refractory symptoms.

Abstract
Background and Aims: Elderly patient might experience an increased risk of complications after laparoscopic Roux-en-Y gastric bypass. We aimed to perform a meta-analysis of comparative studies on this issue in patients aged 60 years or older. Material and Methods: A systematic literature search was performed. Medline, Cochrane Library, Embase, Scopus, and Google Scholar were searched until July 2016 for studies on outcomes of laparoscopic Roux-en-Y gastric bypass in elderly versus younger patients. Primary outcomes were mortality and overall complications. Secondary outcomes were length of hospital stay, excess weight loss percentage, effect on diabetes, hypertension, hyperlipidemia and obstructive sleep apnea. Heterogeneity across the studies was evaluated by the I2 test, and a random effects model was used. Results were expressed as mean difference and risk ratio (RR). Results: Seven studies involving 3128 patients were retrieved and included in this study. A significantly increased risk of mortality and overall complications was observed among patients older than 60 years compared with younger ones (RR, 6.12; 95% confidence interval 1.08–34.83; p = 0.04; RR, 1.51; 95% confidence interval 1.07–2.11; p = 0.02). Particularly, elderly patients experienced 1% increased risk of mortality and 3% increased risk of overall complications. Length of stay, diabetes, and obstructive sleep apnea remission rates were similar among the groups. Excess weight loss percentage was significantly greater among younger patients (mean difference, −3.44; 95% confidence interval −5.20, −1.68; p < 0.001), as were hypertension (RR, 0.57; 95% confidence interval 0.42–0.76; p < 0.001) and hyperlipidemia (RR, 0.61; 95% confidence interval 0.45–0.83; p = 0.002) remission rates. Conclusion: Laparoscopic Roux-en-Y gastric bypass in patients older than 60 years may be a risky bariatric surgery operation due to higher complications and mortality and may not be as effective as in patients younger than 60 years. Thus, older patients should be carefully counseled before this procedure for individual risk–benefit assessment.

Abstract
BACKGROUND Sleeve gastrectomy is a relatively new procedure that developed as a result of rapid innovation in the field of bariatric surgery. As with any newly developed operation, there is a learning curve that potentially can be associated with higher morbidity. Real-time surgical mentoring reduces the learning curve effect but can be time intensive for the mentor. The aim of this initiative was to evaluate the feasibility, effectiveness, and satisfaction of surgical telementoring for laparoscopic sleeve gastrectomy. This is the first national specialty society effort to determine if the "remote presence" of an expert surgeon (mentor) can help practicing surgeons improve skills. METHODS The experience of 15 surgical trainees (mentees) who performed laparoscopic sleeve gastrectomy under real-time telementoring by 7 mentors was reviewed. Telementoring was implemented using the Visitor1® remote presence system with two-way live audio and video communication. The receiving platform utilized a conventional laptop, iPad, or iPhone. The mentee followed a structured telementoring program including didactic learning, live case teleobservation, and telementoring of 2-3 cases. A survey on the quality of the telecommunication and effectiveness of the mentoring was performed by the mentor and mentee on a scale of "exceeded," "met," "almost met," or "failed to meet" expectations. The overall telementoring experience was rated on a scale of 1 for "poor" to 5 for "excellent." RESULTS Based on the mentees' survey, the overall telementoring experience was rated as 4.8. Despite the mentees having experience with laparoscopic sleeve gastrectomy, most commented that the telementoring experience was an excellent educational tool and they learned some new techniques they plan to apply it in their practice. Based on the mentors' survey, the overall telementoring experience was rated as 4.7. All mentors stated that they were satisfied with the telementoring sessions and there were no unexpected intraoperative occurrences. There were some logistical limitations including difficulties in scheduling of cases or the delay of cases. CONCLUSIONS Surgical instruction by telementoring was shown to be feasible, practical, and successful, and was highly rated in this study by both the mentors and mentees. The currently utilized telementoring platform is thus an effective educational tool that can facilitate acquisition of surgical skills and assist with the conventional on-site surgical mentoring model.

The influence of patient- and surgeon-specific factors on operative duration and early postoperative outcomes in shoulder arthroplasty. J Shoulder Elbow Surg 2017; 26:1011-1016. [PMID: 28139387 DOI: 10.1016/j.jse.2016.10.025] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2016] [Revised: 10/06/2016] [Accepted: 10/26/2016] [Indexed: 02/01/2023]
Abstract
BACKGROUND Increased operative duration has been shown to have demonstrable effects on the outcomes and complications in multiple areas of orthopedic surgery. We sought to determine if patient- and surgeon-specific factors correlated to operative duration in shoulder arthroplasty. Our hypothesis was that increased surgeon and trainee volume would decrease operative times and that more complex pathology would increase operative duration. METHODS A retrospective review of primary and revision total and reverse shoulder arthroplasties performed at a single institution from 2012 through 2015 was performed evaluating the correlation between specific patient and surgeon factors and operative duration. The influence of operative duration on postoperative length of stay and risk of readmission within 30 days was also analyzed. RESULTS For surgeon-specific factors, high surgeon volume (>30 shoulder arthroplasties/year) was associated with shorter operative duration (105.9 vs. 128.3 minutes; P < .001). Progression through the fellowship academic year was found to be associated with decreased surgical times (100.7 vs. 116.5 minutes; P < .0001). Certain complex pathologic processes (reverse shoulder arthroplasty for sequelae of prior fracture, total shoulder arthroplasty for dysplastic glenoid morphology, revision surgery) showed increased operative times. Patients with postoperative readmission had a longer mean operative time (163 vs. 107.1 minutes). CONCLUSIONS Increased surgeon and trainee volumes were associated with decreased operative duration in shoulder arthroplasty. Patients with more complex pathology were more likely to have increased surgical times. Postoperative readmission within 30 days was associated with increased operative duration. Consideration of patient selection by surgeons to minimize operative times may reduce readmissions.

Abstract
Bariatric surgery is currently the most effective option for the treatment of morbid obesity and its associated comorbidities. Recent clinical and experimental findings have challenged the role of mechanical restriction and caloric malabsorption as the main mechanisms for weight loss and health benefits. Instead, other mechanisms including increased levels of satiety gut hormones, altered gut microbiota, changes in bile acid metabolism, and/or energy expenditure have been proposed as explanations for benefits of bariatric surgery. Beside the standard proximal Roux-en-Y gastric bypass and the biliopancreatic diversion with or without duodenal switch, where parts of the small intestine are excluded from contact with nutrients, resectional techniques like the sleeve gastrectomy (SG) have recently been added to the armory of bariatric surgeons. The variation of weight loss and glycemic control is vast between but also within different bariatric operations. We surveyed members of the Swiss Society for the Study of Morbid Obesity and Metabolic Disorders to assess the extent to which the phenotype of patients influences the choice of bariatric procedure. Swiss bariatric surgeons preferred Roux-en-Y gastric bypass and SG for patients with type 2 diabetes mellitus and patients with a body mass index >50 kg/m2, which is consistent with the literature. An SG was preferred in patients with a high anesthetic risk or previous laparotomy. The surgeons’ own experience was a major determinant as there is little evidence in the literature for this approach. Although trends will come and go, evidence-based medicine requires a rigorous examination of the proof to inform clinical practice.

Abstract
INTRODUCTION The prevalence of smoking habits in severe obesity is higher than in the general population. There is some evidence that smokers have different temperaments compared to non-smokers. The aim of this study is to evaluate the associations between smoking status (smokers, ex-smokers and non-smokers) and temperament characteristics in bariatric surgery candidates. METHODS We analyzed data on temperament of 420 bariatric surgery candidates, as assessed by the AFECTS scale, in an exploratory cross-sectional survey of bariatric surgery candidates who have been grouped into smokers, ex-smokers and non-smokers. RESULTS We detected significant statistical differences in temperament related to the smoking status in this population after controlling the current use of psychiatric medication. Smokers had higher anxiety and lower control than non-smokers. Ex-smokers with BMI >50 kg/m(2) presented higher coping and control characteristics than smokers. CONCLUSIONS Smoking in bariatric surgery candidates was associated with lower control and higher anxious temperament, when controlled by current use of psychiatric medication. Smokers with BMI >50 kg/m(2) presented lower coping and control than ex-smokers. Assessment of temperament in bariatric surgery candidates may help in decisions about smoking cessation treatment and prevention of smoking relapse after surgery.

Abstract
OBJECTIVE Despite following international guidelines and conducting routine preoperative dietary counseling, every bariatric surgeon will encounter technical challenges in laparoscopic gastric bypass surgery. We present a series of patients in whom the bariatric procedure was stopped after encountering insufficient exposure during diagnostic laparoscopy. These patients were sent back for dietary counseling and underwent surgery after conservative weight loss. The data from this two-step procedure are analyzed and discussed. METHODS This concept was applied and studied in 14 patients from a series of 620 bariatric procedures. Patients who underwent a primary laparoscopic gastric bypass (n = 593) were used as references. RESULTS The patients in the study group were significantly heavier than those in the reference group (165 vs. 127 kg, p < 0.001), with 79 % having a BMI >50 kg/m(2). The patients lost a median of 11 kg after 2 months of conservative treatment, and the mean BMI decreased from 55.7 to 52.6 kg/m(2). All the patients in the study group underwent laparoscopic surgery for the second procedure with no need for conversion. The complication rate was not elevated in the study group. Overall hospital costs were higher for the study group compared with those for the primary laparoscopic bypass group (27,136 vs. 19,601 USD, p = 0.034). CONCLUSION The primary laparoscopic procedure can be stopped in patients with insufficient exposure instead of having them undergo conversion to open surgery. These patients may undergo successful laparoscopic procedures after conservative weight loss with no increased risk and with all of the possible benefits of a laparoscopic approach. As a result of this study, we have established a fixed, preoperative lower limit of 10 % excess weight reduction before accepting superobese patients (BMI >50 kg/m(2)) for surgery at our hospital.

Abstract
BACKGROUND Venous thromboembolism is the most common preventable cause of hospital death. The objective of this study was to clarify risk factors for postoperative bleeding related to thromboprophylaxis after laparoscopic colorectal cancer surgery. METHODS The study was conducted at 23 Japanese institutions and included patients with colorectal cancer who underwent laparoscopic or open surgery followed by fondaparinux treatment. We performed a retrospective analysis from a prospectively maintained database. We used multivariate analyses to evaluate clinical risk factors for prophylaxis-related bleeding events. RESULTS After multivariate analysis, male gender, intraoperative blood loss of less than 25 mL, and a preoperative platelet count below 15 × 104/μL were found to be independent risk factors in the laparoscopic surgery group. Only the preoperative platelet count was an independent risk factor in the open surgery group. CONCLUSIONS Different prophylactic treatments for postoperative venous thromboembolism may be necessary in laparoscopic vs open surgery for colorectal cancer.

Abstract
Controversy exists regarding the effectiveness and safety of bariatric/metabolic surgery in elderly patients. We performed a systematic review on this issue in patients aged 60 years or older. MEDLINE, Cochrane Library, Embase, Scopus, and Google Scholar were searched until August 2015 for studies on outcomes of bariatric surgery in elderly patients. The results were expressed as pooled proportions (%) with 95% confidence intervals. Heterogeneity across the studies was evaluated by the I2 test, and a random-effects model was used. Twenty-six articles encompassing 8,149 patients were pertinent with this issue and included data on bariatric surgery outcomes in elderly population. Fourteen patients died during the 30-day postoperative period, with a pooled mortality of 0.01%. Pooled overall complication rate was 14.7%. At 1-year follow-up, pooled mean excess weight loss was 53.77%, pooled diabetes resolution was 54.5%, and pooled hypertension resolution was 42.5%, while pooled lipid disorder resolution was 41.2%. Outcomes and complication rates of bariatric surgery in patients older than 60 years are comparable to those in a younger population, independent of the type of procedure performed. Patients should not be denied bariatric surgery because of their age alone.

Abstract
BACKGROUND Obesity is increasingly prevalent disease worldwide and bariatric surgery is the most effective treatment for the most severe cases. The Roux-en-Y gastric bypass is still the most used technique all over the world and the laparoscopic approach has been preferred by surgeons with different approaches, propositions and techniques in performing the procedure. AIM To report the surgical aspects of the systematization and results of the simplified laparoscopic gastric bypass (Brazilian technique). METHODS Were included all patients undergoing this procedure from January 2001 to July 2014; were described and analyzed aspects of this technique, the systematization and complications associated with the procedure. RESULTS A total of 12,000 patients (72% women) were included, with a mean age of 43 years (14-76) and a mean BMI of 44.5 (35-90 kg/m2). Mean total operative time was 72 minutes (36-270) and the mean hospital stay was 36 hours. There were 303 cases of gastrojejunostomy stenosis (2.5%), 370 patients had gastrointestinal bleeding (3%) with only one lap revision due to a enteroanastomosis bleeding and six revisions related to intestinal obstruction caused by impacted clots in the jejunojenunostomy. Blood transfusion was needed in 32 patients (0.3%); Petersen hernia was diagnosed in 18 (0.15%) and digestive fistula in 54 (0.45%), which led to reoperation in 43 of them (67%). The overall mortality was 0.1% (fistula with sepsis=8, pulmonary thromboembolism=3; intestinal obstruction associated with sepsis=1). CONCLUSION The simplified laparoscopic gastric bypass is a feasible and safe option with low complication rate and easy reproducibility for education and training in bariatric surgery.

Abstract
In 2012, an expert panel composed of presidents of each of the societies, the European Chapter of the International Federation for the Surgery of Obesity (IFSO-EC), and of the European Association for the Study of Obesity (EASO), as well as of the chair of EASO Obesity Management Task Force (EASO OMTF) and other key representatives from IFSO-EC and EASO, devoted the joint Medico-Surgical Workshop of both institutions to the topic of metabolic surgery in advance of the 2013 European Congress on Obesity held in Liverpool. This meeting was prompted by the extraordinary advancement made in the field of metabolic and bariatric surgery during the past decade. It was agreed to revise and update the 2008 Interdisciplinary European Guidelines on Surgery of Severe Obesity produced by focusing in particular on the evidence gathered in relation to the effects on diabetes and the changes in the recommendations of patient eligibility criteria. The expert panel allowed the coverage of key disciplines in the comprehensive management of obesity and obesity-associated diseases, aimed specifically at updating the clinical guidelines to reflect current knowledge, expertise and evidence-based data on metabolic and bariatric surgery.

Abstract
BACKGROUND This study aimed primarily to evaluate the safety of digestive running suture (in gastrojejunal and antecolic jejunojejunal anastomosis closure) using unidirectional absorbable barbed suture (V-Loc 180) in laparoscopic Roux-en-Y gastric bypass (LRYGB) and secondarily to assess the efficacy of V-Loc 180 in reducing operative time. METHODS A prospective cohort study of 315 consecutive patients who underwent LRYGB was performed between October 2009 and October 2012 using an identical procedure technique. For the first 76 patients, a multifilament absorbable suture was used to assess the gastrojejunal anastomosis and the antecolic jejunal suture. For the following 239 patients, a unidirectional barbed monofilament suture was used. Data including operative time, time required for gastric pouch creation, time spent in both anastomoses constructions, conversion rate, and complications were prospectively recorded. RESULTS The postoperative complications did not differ significantly between the two groups. Early complications were observed for 1 patient (1.3%) in the multifilament group and for 14 patients (5.8%) in the barbed procedure group (p > 0.05). Late complications were observed for 1 patient (1.3%) in the multifilament group and for 5 patients (2%) in the barbed procedure group (p > 0.05). A shortened operative time was achieved in the barbed suture group. The mean operative time was 74.3 ± 15.3 min in the Vicryl group versus 62.7 ± 15.5 min in the V-Loc group (p < 0.05). The mean operative time required to fashion the gastrojejunal anastomosis was 21.3 ± 6.3 min in the Vicryl group versus 17.4 ± 5.1 min in the V-Loc group (p < 0.05). The mean operative time required to fashion the jejunojejunal anastomosis was 21.4 ± 4.9 min in the Vicryl group versus 15.2 ± 5.5 min in the V-Loc group (p < 0.05). CONCLUSIONS The authors' experience has demonstrated that the use of interlocked V-Loc suture during LRYGB anastomosis appears to be safe and efficient. The findings show a shortened total operative time in terms of single gastrojejunal or jejunojejunal anastomosis time. No statistically significant differences in early or late postoperative complications were observed between the V-Loc and multifilament absorbable suture patients.

Abstract
Obesity is recognized as a global health crisis. Bariatric surgery offers a treatment that can reduce weight, induce remission of obesity-related diseases, and improve the quality of life. In this article, we outline the different options in bariatric surgery and summarize the recommendations for selecting and assessing potential candidates before proceeding to surgery. We present current data on post-surgical outcomes and evaluate the psychosocial and economic effects of bariatric surgery. Finally, we evaluate the complication rates and present recommendations for post-operative care.

Abstract
OBJECTIVE : To analyze the potential effects of preoperative age on postoperative weight loss in patients who underwent Roux-en-Y gastric bypass (RYGBP) with long-term follow-up data. BACKGROUND : The reasons for individual differences in surgically induced weight loss are not completely understood. To date, there are no available studies specifically aimed at analyzing the effects of age on weight loss in patients undergoing the same operation and with long-term follow-up data. METHODS : Retrospective analysis of prospectively collected data for all patients who underwent RYGBP between 2006 and 2010. To evaluate weight loss, we used preoperative and follow-up body mass index (BMI), analyzed by the mixed-effects linear model for repeated measures. To evaluate age effects, patients were classified in quartiles (≤35 years, 36-42 years, 43-51 years, ≥52 years). RESULTS : A total of 489 patients entered the study; preoperatively, the younger group showed a significantly higher BMI (mean BMI: 48.2 in patients aged ≤35 years, 46.9 in 36-42 years, 45.5 in 43-51 years, 45.7 in ≥52 years, P = 0.014) and a higher percentage of super-obesity (41.6% among patients aged ≤35 years, 28.1% among 36-42 years, 27.6% among 43-51 years, 28.3% among ≥ 52 years, P = 0.047). In spite of this, younger patients experienced a significantly greater and prolonged BMI decrease during the entire follow-up period and the BMI trend over time resulted significantly modified according to age quartiles (P = 0.036). CONCLUSIONS : This study provides a new prognostic factor in bariatric surgery: patient age. Because advanced age represents a risk factor for complications and mortality, and given that bariatric surgery may not be as effective in older patients compared to younger subjects, we believe that surgical indications in patients older than 50 years should be carefully weighed up.

Abstract
In 2012, an outstanding expert panel derived from IFSO-EC (International Federation for the Surgery of Obesity-European Chapter) and EASO (European Association for the Study of Obesity), composed by key representatives of both Societies including past and present presidents together with EASO's OMTF (Obesity Management Task Force) chair, agreed to devote the joint Medico-Surgical Workshop of both institutions to the topic of metabolic surgery as a pre-satellite of the 2013 European Congress on Obesity (ECO) to be held in Liverpool given the extraordinarily advancement made specifically in this field during the past years. It was further agreed to revise and update the 2008 Interdisciplinary European Guidelines on Surgery of Severe Obesity produced in cooperation of both Societies by focusing in particular on the evidence gathered in relation to the effects on diabetes during this lustrum and the subsequent changes that have taken place in patient eligibility criteria. The expert panel composition allowed the coverage of key disciplines in the comprehensive management of obesity and obesity-associated diseases, aimed specifically at updating the clinical guidelines to reflect current knowledge, expertise and evidence-based data on metabolic and bariatric surgery.

Abstract
Bariatric surgery can effectively reduce body weight and treat obesity associated metabolic diseases such as diabetes mellitus. There are also benefits for an individual's functional status and psychological health. A multi-disciplinary evaluation should be offered to the individual as the first essential step in considering bariatric surgery as a treatment. This evaluation should include a thorough medical assessment, as well as psychological and dietetic assessments. In this best practice article, we outline the current recommendations for referral for bariatric surgery. We also present the data for pre-operative assessment before bariatric surgery, with particular reference to cardiovascular disease and obstructive sleep apnoea. We describe the literature on outcomes after bariatric surgery, including the results for mortality, weight loss, remission of diabetes and associated endocrine disorders such as hypogonadism. Within this review, we will illustrate the impact of bariatric surgery on self-image, psychological health and perceived health and functional status. Finally, we briefly detail the potential complications of bariatric surgery, and offer advice on post-operative care and surveillance.

Abstract
BACKGROUND Resident work hour reforms were developed by Aga Khan University Postgraduate Medical education committee in the year 2005. These reforms were implemented by the section of Orthopedics in winter 2006. We designed this study to determine if there is a difference in morbidity and mortality following Dynamic Hip Screw (DHS) fixation for intertrochanteric fracture patients before and after implementation of work hour reforms. METHODS Patients who underwent DHS fixation for inter-trochanteric fracture from January 2005 to December 2008 were included. These patients were divided into two groups. Group A included those patients who underwent DHS fixation prior to the implementation of work hour reforms and Group B patients had their hip fracture surgery after the implementation of these reforms. RESULTS The mean operative time was 1.6±0.6 h and 1.3±0 h for group A and B patients respectively (p<0.001). There was no change in the rates of wound infection, length of hospital stay, post operative ambulation status, inadequate fixation, repeat surgeries and mortality in the two groups. CONCLUSION Resident work hour reform was associated with a significant decrease in the mean operative time for patients undergoing DHS fixation. However morbidity and mortality following DHS fixation for Intertrochanteric fractures has not decreased after implementation of these reforms. Further research evaluating patient outcomes in orthopedic surgery following work-hour restrictions are needed. Moreover, the impact of these reforms on the educational and research activities of the residents also needs to be determined.

Abstract
OBJECTIVE To provide evidence-based guidelines for patient selection and to recommend the medical and nutritional aspects of multidisciplinary care required to minimize perioperative and postoperative risks in patients with severe obesity who undergo weight loss surgery (WLS). RESEARCH METHODS AND PROCEDURES Members of the Multidisciplinary Care Task Group conducted searches of MEDLINE and PubMed for articles related to WLS in general and medical and nutritional care in particular. Pertinent abstracts and literature were reviewed for references. Multiple searches were carried out for various aspects of multidisciplinary care published between 1980 and 2004. A total of 3000 abstracts were identified; 242 were reviewed in detail. RESULTS We recommended multidisciplinary screening of WLS patients to ensure appropriate selection; preoperative assessment for cardiovascular, pulmonary, gastrointestinal, endocrine, and other obesity-related diseases associated with increased risk for complications or mortality; preoperative weight loss and cessation of smoking; perioperative prophylaxis for deep vein thrombosis and pulmonary embolism (PE); preoperative and postoperative education and counseling by a registered dietitian; and a well-defined postsurgical diet progression. DISCUSSION Obesity-related diseases are often undiagnosed before WLS, putting patients at increased risk for complications and/or early mortality. Multidisciplinary assessment and care to minimize short- and long-term risks include: comprehensive medical screening; appropriate pre-, peri-, and postoperative preparation; collaboration with multiple patient care disciplines (e.g., anesthesiology, pulmonary medicine, cardiology, and psychology); and long-term nutrition education/counseling.

Abstract
BACKGROUND This study purposed to explore the impact of hospital volume and surgeon volume on hospital resource utilization after bariatric surgery and to identify the predictors of length of stay (LOS) and hospital treatment cost in a nationwide population in Taiwan. METHODS This population-based cohort study retrospectively analyzed 2,674 bariatric surgery procedures performed from 1997 to 2008. Hospitals were classified as low- and high-volume hospitals if their annual number of bariatric surgeries were <35 and ≥ 35, respectively. Surgeons were classified as low- and high-volume surgeons if their annual number of bariatric surgeries were <15 and ≥ 15, respectively. Hierarchical linear regression models were used to predict LOS and hospital treatment cost. RESULTS The mean LOS was 7.67 days and the LOS for high-volume hospitals/surgeons was, on average, 28%/31% shorter than that for low-volume hospitals/surgeons. The mean hospital treatment cost was US$2,344.08, and the average hospital costs for high-volume hospitals/surgeons were 10%/13% lower than those for low-volume hospitals/surgeons. Advanced age, male gender, high Charlson co-morbidity index, and current treatment in a low-volume hospital, by a low-volume surgeon, and via open gastric bypass were significantly associated with long LOS and high hospital treatment cost (P < 0.001). CONCLUSIONS The data suggest that annual surgical volume is the key factor in hospital resource utilization. The results improve the understanding of medical resource allocation for this surgical procedure and can help to formulate public health policies for optimizing hospital resource utilization for related diseases.

Abstract
CONTEXT: Superobese patients who undergo gastric bypass have a greater incidence of complications. The greater incidence of comorbidity in this group leads to a higher surgical risk, and a need for special care. By analyzing the risk factors identified in the preoperative period, scoring them, constructing a score and assessing the occurrence of serious complications and death, we will have elements to identify which patients are at greater risk. OBJECTIVE: To determine the accuracy of the Recife Score for predicting serious postoperative complications and death in superobese patients who undergo Roux-en-Y gastric bypass surgery by the conventional method. METHODS: An ambidirectional study was conducted to validate the diagnostic test on 203 severely obese patients submitted to Roux-en-Y gastric bypass at the Hospital das Clínicas of the Federal University of Pernambuco, Recife, PE, Brazil, from September 1997 to May 2007. The dependent variables were major postoperative complications and death. The independent variable was the Recife Score. The data were analyzed using the Epi-Info 3.5.1 program. The accuracy of the Recife Score was analyzed considering the following parameters: sensitivity, specificity, positive predictive value, negative predictive value, positive verisimilitude ratio and negative verisimilitude ratio. RESULTS: The accuracy of the Recife Score with cut-off points higher than 3 and higher than 5 to predict serious postoperative complications was, respectively, a frequency of complications of 12.3%, with a risk ratio of 2.83, sensitivity of 57.1% and specificity of 69.8%, and 12.5%, with a risk ratio of 1.88, sensitivity of 7.1% and specificity of 96.3%. The accuracy of the Recife Score with cut-off points higher than 3 and higher than 5 to predict death was, respectively, a frequency of death of 7.7%, with a risk ratio of 10.62, sensitivity of 83.3% and specificity of 69.5%, and 12.5%, with a risk ratio of 4.88, sensitivity of 16.7% and specificity of 96.5%. CONCLUSION: A Recife Score >3 prior to conventional gastric bypass presents a high level of accuracy in the prediction of serious postoperative complications and death.

Abstract
BACKGROUND Although several risk factors affecting weight loss outcomes with bariatric procedures have been identified, the effect of age, gender, race, and illness severity on postoperative outcomes of laparoscopic gastric bypass has not been extensively examined. METHODS The University HealthSystem Consortium database is an administrative and financial database that provides information on the inpatient stay. A retrospective analysis of patient outcomes was performed using 4-year discharge data from the University HealthSystem Consortium database. RESULTS A total of 37,765 patients underwent laparoscopic gastric bypass. The women exhibited significantly reduced mortality, morbidity, intensive care unit (ICU) admissions (9.87% male versus 6.73% female; P <.001), duration of hospitalization (2.72 ± 4.03 d for men versus 2.59 ± 2.88 d for women; P <.001), and hospital costs ($17,346 ± $15,397 for men versus $14,383 ± $11,170 for women; P <.001). Blacks demonstrated significantly greater 30-day readmission rates, duration of hospitalization, and costs compared with whites. Hispanics had lower ICU admission and hospital costs compared with whites. With increasing age, an increased risk of overall morbidity, ICU admissions, duration of hospitalization, and costs was observed. Compared with the minor severity group, the major/extreme severity group had significantly greater observed mortality, overall morbidity, ICU admissions, duration of hospitalization, and hospital costs. CONCLUSION The present study identified gender, race, age, and illness severity as risk factors affecting postoperative outcomes after laparoscopic gastric bypass. Male gender and increasing age were overall associated with an increased risk of complications. Significant racial disparities in the outcome measures were observed with blacks having an increased risk of adverse events. Illness severity was shown to adversely affect the surgical outcomes in laparoscopic gastric bypass.

Abstract
BACKGROUND The objective of this study was to determine the relationship between perioperative complications and the severity of obstructive sleep apnoea (OSA) in patients undergoing bariatric surgery who had undergone preoperative polysomnography (PSG). METHODS The records of 797 patients, age >18 yr, who underwent bariatric operations (442 open and 355 laparoscopic procedures) at Mayo Clinic and were assessed before operation by PSG, were reviewed retrospectively. OSA was quantified using the apnoea-hypopnoea index (AHI) as none (≤ 4), mild (5-15), moderate (16-30), and severe (≥ 31). Pulmonary, surgical, and 'other' complications within the first 30 postoperative days were analysed according to OSA severity. Logistic regression was used to assess the multivariable association of OSA, age, sex, BMI, and surgical approach with postoperative complications. RESULTS Most patients with OSA (93%) received perioperative positive airway pressure therapy, and all patients were closely monitored after operation with pulse oximetry on either regular nursing floors or in intensive or intermediate care units. At least one postoperative complication occurred in 259 patients (33%). In a multivariable model, the overall complication rate was increased with open procedures compared with laparoscopic. In addition, increased BMI and age were associated with increased likelihood of pulmonary and other complications. Complication rates were not associated with OSA severity. CONCLUSIONS In obese patients evaluated before operation by PSG before bariatric surgery and managed accordingly, the severity of OSA, as assessed by the AHI, was not associated with the rate of perioperative complications. These results cannot determine whether unrecognized and untreated OSA increases risk.

Abstract
BACKGROUND Weight loss improves the cardiovascular and metabolic risk associated with obesity. However, insufficient data are available about the health effects of weight gain, separate from the obesity itself. We sought to determine whether the changes in body weight before open gastric bypass surgery (OGB) would have a significant effect on the immediate perioperative hospital course. METHODS A retrospective chart review of 100 consecutive patients was performed to examine the effects of co-morbidities and body weight changes in the immediate preoperative period on the hospital length of stay and the rate of admission to the surgical intensive care unit (SICU). RESULTS Of our class III obese patients undergoing OGB, 95% had ≥1 co-morbid condition and an overall SICU admission rate of 18%. Compared with the patients with no perioperative SICU admission, the patients admitted to the SICU had a greater degree of insulin resistance (homeostatic model analysis-insulin resistance 10.8 ± 1.3 versus 5.9 ± 0.5, P = .001), greater serum triglyceride levels (225 ± 47 versus 143 ± 8 mg/dL, P = .003), and had gained more weight preoperatively (.52 ± .13 versus .06 ± .06 lb/wk, P = .003). The multivariate analyses showed that preoperative weight gain was a risk factor for a longer length of stay and more SICU admissions lasting ≥3 days, as were a diagnosis of sleep apnea and an elevated serum triglyceride concentration. CONCLUSION The results of the present retrospective study suggest that weight gain increases the risk of perioperative SICU admission associated with OGB, independent of the body mass index. Sleep apnea and elevated serum triglyceride levels were also important determinants of perioperative morbidity. In view of the increasing epidemic of obesity and the popularity of bariatric surgical procedures, we propose that additional clinical and metabolic research focusing on the understanding of the complex relationship among obesity, positive energy balance, weight gain, and perioperative morbidity is needed.

Abstract
BACKGROUND The objective of this study is to evaluate the long-term outcomes following laparoscopic Roux-en-Y gastric bypass (LREYGB) in veteran patients. The VA bariatric population differs from its counterpart in the private sector by the predominance of a male population, a higher percentage of patients from a lower socioeconomic background, a higher mean age, and a higher rate of obesity-related comorbidities. METHODS A retrospective review with prospectively collected data was used to analyze postoperative changes of comorbidities and percent of excess weight loss (% EWL) in consecutive patients who underwent LREYGB between August 2003 and September 2006. RESULTS Among 70 patients, 73% were men with a mean age of 52 years (29-66 years). Average preoperative weight and body mass index were 310 lbs (224-397 lbs) and 46 kg/m(2) (36-60 kg/m(2)), respectively. The incidence of major and minor complications was 1.4% and 15.7%, respectively. There were no mortalities. Follow-up (f/u) was possible in all patients. At a mean f/u rate of 39 months, % EWL was 56%. At 1, 3, and 5 years, % EWL was 61%, 53%, and 59%, respectively. Thirty-five patients (50%) had type 2 diabetes mellitus (T2DM). Glycosylated hemoglobin concentrations returned to normal levels in 91% of patients and improved in an additional 6% of T2DM cases. Only 7% of patients are still maintained on antidiabetic medications. In patients with more than 1 year f/u, most other comorbidities were improved or resolved. CONCLUSIONS Long-term f/u of LREYGB in veteran patients demonstrated significant and durable weight loss (56% EWL) with marked improvements in comorbidities especially T2DM.

Abstract
BACKGROUND Research has demonstrated that laparoscopic Roux-en-Y gastric bypass patients with a lifetime history of a mood disorder have a lower percentage of excess weight loss (%EWL) compared with patients without this lifetime history. No studies have examined the effect of psychiatric history on postoperative outcomes among laparoscopic sleeve gastrectomy (LSG) patients. The objectives of the present study were to determine whether mood disorders relate to the first year of weight loss for patients undergoing LSG at an academic medical center. METHODS A total of 104 patients (78.6% white and 71.2% women), with a median body mass index of 60.35 kg/m(2) (range 31.37-129.14) underwent LSG. The patients were prospectively followed up at 1, 3, 6, 9, and 12 months. The semistructured preoperative psychiatric evaluations demonstrated that 43.1% had a current, and 62.5% a lifetime, diagnosis of a mood disorder. RESULTS LSG patients with current mood disorders had a significantly lower %EWL than patients without a psychiatric diagnosis at the 1-, 3-, 6-, and 9-month follow-up visits. LSG patients with a lifetime history of a mood disorder had a significantly lower %EWL than patients without psychiatric diagnosis at the 1-, 9-, and 12-month follow-up examinations. However, after removing patients with bipolar disorder from the analyses, no significant differences were found in the %EWL between patients with and without a lifetime history of depressive disorders. CONCLUSION Consistent with the laparoscopic Roux-en-Y gastric bypass findings, a lifetime history of mood disorders appears to be associated with significantly less weight loss in LSG patients. These findings highlight the importance of the psychiatric assessment in bariatric patients. Additionally, patients with a current or lifetime history of mood disorders might need additional pre- and postoperative care to improve their outcomes.

Abstract
Background Various techniques of laparoscopic Roux-en-Y gastric bypass have been described. We completely standardized this procedure to minimize its sometimes substantial morbidity and mortality. This study describes our experience with the standardized fully stapled laparoscopic Roux-en-Y gastric bypass (FS-LRYGB) and its influence on the 30-day morbidity and mortality. Methods We retrospectively analyzed 2,645 patients who underwent FS-LRYGB from May 2004 to August 2008. Operative time, hospital stay and readmission, re-operation, and 30-day morbidity/mortality rates were then calculated. The 30-day follow-up data were complete for 2,606 patients (98.5%). Results There were 539 male and 2,067 female patients. Mean age was 39.2 years (range 14–73), mean BMI 41.44 kg/m2 (range, 23–75.5). The mean hospital stay was 3.35 days (range 2–71). Mean total operative time was 63 min (range 35–150). One patient died of pneumonia within 30 days of surgery (0.04%). One hundred and fifty one (5.8%) patients had postoperative complications as follows: gastrointestinal hemorrhage (n = 89, 3.42%), intestinal obstruction (n = 9, 0.35%), anastomotic leak (n = 5, 0.19%) and others (n = 47, 1.80%). In 66 patients, the bleeding resolved without any surgical re-intervention. One hemorrhage resulted in hypovolemic shock with subsequent renal and hepatic failure. Conclusion The systematic approach and the full standardization of the FS-LRYGB procedure contribute highly to the very low mortality and the low morbidity rates in our institution. Gastrointestinal bleeding appears to be the commonest complication, but is self-limiting in the majority of cases. Our approach also significantly reduces operative time and turns the technically demanding laparoscopic Roux-en-Y gastric bypass procedure into an easy reproducible operation, effective for training.

Abstract
INTRODUCTION The prevalence of obesity surgery is increasing rapidly in the UK as demand rises. Consequently, general surgeons on-call may be faced with the complications of such surgery and need to have an understanding about how to manage them, at least initially. Obesity surgery is mainly offered in tertiary centres but patients may present with problems to their local district hospital. This review summarises the main complications that may be encountered. MATERIALS AND METHODS A full literature search was carried out looking at articles published in the last 10 years. Keywords for search purposes included bariatric, surgery, complications, emergency and management. CONCLUSIONS Complications of bariatric surgery have been extensively written about but never in a format that is designed to aid the on-call surgeon. The intricate details and rare complications have been excluded to concentrate on those symptoms and signs that are likely to be encountered by the emergency team.
