RESUMEN
PURPOSE: The aim of this study was to investigate the actual incidence of symptomatic Petersen's hernias (PH) as well as identify risk factors for their occurrence. METHODS: Search was performed in Medline (via PubMed), Web of Science, and Cochrane library, using the keywords "Petersen Or Petersen's AND hernia" and "Internal hernia." Only studies of symptomatic PH were eligible. Fifty-three studies matched our criteria and were included. Risk of bias for each study was independently assessed using the checklist modification by Hoy et al. Analysis was performed using random-effects models, with subsequent subgroup analyses. RESULTS: A total of 81,701 patients were included. Mean time interval from index operation to PH diagnosis was 17.8 months. Total small bowel obstruction (SBO) events at Petersen's site were 737 (0.7%). SBO incidence was significantly higher in patients without defect closure (1.2% vs 0.3%, p < 0.01), but was not significantly affected by anastomosis fashion (retrocolic 0.7% vs antecolic 0.8%, p = 0.99). SBO incidence was also not significantly affected by the surgical approach (laparoscopic = 0.7% vs open = 0.1%, p = 0.18). However, retrocolic anastomosis was found to be associated with marginally, but not significantly, increased SBO rate in patients with Petersen's space closure, compared with the antecolic anastomosis (p = 0.09). CONCLUSION: PH development may occur after any gastric operation with gastrojejunal anastomosis. Contrary to anastomosis fashion and surgical approach, defect closure was demonstrated to significantly reduce SBO incidence. Limitations of this study may include the high heterogeneity and the possible publication bias across the included studies.

PURPOSE: Floppy eyelid syndrome (FES) is a clinical entity characterized by palpebral hyperlaxity and chronic conjunctivitis. Patients' eyelids evert ("flip inside out"), leading to eye irritation, dryness, grittiness, and tearing. More severe cases can lead to significant ocular complications, such as keratoconus and impaired eyesight. Research has revealed an association between FES and obstructive sleep apnea syndrome (OSAS). OSAS is also one of the most common comorbidities among patients with obesity and an indication for bariatric surgery. This is one of the first studies to explore FES in a group of patients who have undergone bariatric surgery. MATERIALS AND METHODS: This was a retrospective study. A total of 88 patients completed a survey by mail or telephone. Additional data on demographics and baseline preoperative clinical information was extracted from the online medical records and the MBSAQIP database. RESULTS: Thirty-nine patients (44%) recalled having chronic ocular symptoms before their bariatric surgery, among whom six reported palpebral laxity and/or an established diagnosis of FES. The majority of them (67%) rated their symptoms postoperatively as "somewhat" or "significantly improved." The patients that reported improvement in their ocular symptoms also experienced an improvement in their OSAS severity. CONCLUSION: Bariatric surgery might affect the clinical course of FES and the severity of symptoms. Treating OSAS, the underlying mechanism of FES, is a possible mechanism of how bariatric surgery can help patients. It is also critical for bariatric surgeons to consider FES when patients with obesity, particularly those with OSAS, present with chronic eye symptoms.

PURPOSE: To evaluate the long-term outcomes of revisional malabsorptive bariatric surgery. MATERIALS AND METHODS: Malabsorptive bariatric procedures are increasingly performed in the revisional setting. We collated and analysed prospectively recorded data for all patients who underwent a revisional Biliopancreatic diversion + / - duodenal switch (BPD + / - DS) over a 17-year period. RESULTS: We identified 102 patients who underwent a revisional BPD + / - DS. Median follow-up was 7 years (range 1-17). There were 21 (20.6%) patients permanently lost to follow-up at a median of 5 years postoperatively. Mean total weight loss since the revisional procedure of 22.7% (SD 13.4), 20.1% (SD 10.5) and 17.6% (SD 5.5) was recorded at 5, 10 and 15 years respectively. At the time of revisional surgery, 23 (22.5%) patients had diabetes and 16 (15.7%) had hypercholesterolaemia with remission of these occurring in 20 (87%) and 7 (44%) patients respectively. Nutritional deficiencies occurred in 82 (80.4%) patients, with 10 (9.8%) patients having severe deficiencies requiring periods of parenteral nutrition. Seven (6.9%) patients required limb lengthening or reversal procedures. There were 16 (15.7%) patients who experienced a complication within 30 days, including 3 (2.9%) anastomotic leaks. Surgery was required in 42 (41.2%) patients for late complications. CONCLUSION: Revisional malabsorptive bariatric surgery induces significant long-term weight loss and comorbidity resolution. High rates of temporary and permanent attrition from follow-up are of major concern, given the high prevalence of nutritional deficiencies. These data question the long-term safety of malabsorptive bariatric procedures due to the inability to ensure compliance with nutritional supplementation and long-term follow-up requirements. KEY POINTS: ⢠Revisional bariatric surgery workload is increasing ⢠Revisional malabsorptive surgery is efficacious for weight loss and comorbidity resolution ⢠Revisional malabsorptive surgery is associated with high rates of nutritional deficiencies ⢠Attrition from follow-up in this specific cohort of patients is of particular concern due to the risk of undiagnosed and untreated nutritional deficiencies.

BACKGROUND: Intragastric balloon (IGB) use is indicated for patients whose BMI precludes the option of bariatric surgery or who need to lose weight prior to undergoing surgery. It is a minimally invasive procedure and currently there are two main models of IGBs in use, the non-adjustable intragastric balloon (NIB), implanted for six months, and the adjustable intragastric balloon (AIB), implanted for up to 12 months. OBJECTIVE: Analyze clinical characteristics between patients receiving non-adjustable gastric balloon and the adjustable (prolonged implantation) intragastric balloon. METHODS: This was a cross-sectional study of 470 patients diagnosed as obese or overweight who had balloon implantation from October 2011 to July 2018. The associations between percentage excess weight loss versus clinical and demographic variables were calculated using the chi-squared test. Independent samples were submitted to the Student's t test to determine the quantitative variables, with a confidence interval of 95%. Calculation of excess weight was based on an estimated ideal weight that would correspond to a BMI of 24.99 kg/m2. RESULTS: A total of 414 patients completed the treatment achieving an average total body weight loss (%TBWL) of 15.4±7 with the NIB and 15.5±9.6 with the AIB. Overweight patients achieved higher excess weight loss (%EWL) values using AIBs (157.2±82.5) and obese patients did so with NIB use (56±29.7). Women achieved higher %EWL values (65.6±62.2) than men (48±27.1). Individuals who attended >4 consultations with a nutritionist (60.8%) achieved TBWL >18%. All of those P-values were <0.001. CONCLUSION: Obese individuals and women registered the greatest weight losses. Overweight patients achieved greater losses using AIB and obese patients did so using NIBs. NIB use was associated with higher EWL percentages. Nutritional accompaniment had a positive impact on the %TBWL.

RESUMO CONTEXTO: O uso do balão intragástrico (BIG) é indicado para pacientes cujo IMC contraindica a cirurgia bariátrica ou que necessitam perder peso antes da cirurgia. É um procedimento minimamente invasivo e atualmente existem dois modelos principais de BIG - o balão intragástrico não ajustável (BINA), implantado por seis meses, e o balão intragástrico ajustável (BIA), por até 12 meses. OBJETIVO: Analisar os fatores associados aos resultados clínicos comparando o uso de balão intragástrico não ajustável com o uso de balão intragástrico ajustável. MÉTODOS: Estudo transversal em 470 pacientes, com sobrepeso ou obesidade, submetidos ao tratamento entre outubro 2011 e julho de 2018. A associação entre as porcentagens da perda de excesso de peso (%PEP) e da perda do peso total (%PPT) com as variáveis demográficas e clínicas foram calculados com o teste qui-quadrado (P<0,05). Foi utilizado o teste t de Student para amostras independentes para comparar variáveis quantitativas, com IC 95%. O cálculo do excesso de peso foi estimado em peso ideal correspondente a um IMC de 24.99 kg/m2. RESULTADOS: Um total de 414 pacientes realizaram o tratamento até o final, com %PPT média de 15,4±7 no BINA e 15,5±9,6 no BIA. Os com sobrepeso apresentaram maiores %PEP no BIA (157,2±82,5) e os obesos maiores %PEP no BINA (56±29,7), com P<0,001. Mulheres (65,6±62,2) apresentaram maiores %PEP do que homens (48±27,1), com P<0,001. Os indivíduos que atenderam a >4 consultas com nutricionista obtiveram %PPT >18% (60,8%), com P<0,001. CONCLUSÃO: Obesos e mulheres tiveram maiores perdas ponderais. Maior perda de peso foi identificada em pacientes com sobrepeso que utilizaram BIA e em obesos os quais utilizaram BINA. O BINA esteve associado com maiores taxas de %PEP. O acompanhamento nutricional impactou positivamente na %PPT.

Central obesity is the main risk factor for obstructive sleep apnea (OSA). Whether there exists a central-obesity anthropometric that better explains apnea-hypopnea index (AHI) variability in the general population and in sleep cohorts is unknown, and this is even less explored among increasing grades of obesity. The objective of the study is to investigate whether there is an anthropometric that better explains AHI variability in a sample of morbidly obese women awaiting bariatric surgery (BS). A prospective multicentre cross-sectional study was conducted in consecutive women before BS. Demographic and anthropometric characteristics included age, body mass index (BMI), neck circumference (NC), waist circumference (WC), hip circumference (HC) and waist-to-hip ratio (WHR). OSA was diagnosed by polysomnography. The capacity of anthropometrics to explain AHI variance was investigated using regression linear models. A total of 115 women were evaluated: age, 44 ± 10 years; BMI, 46 ± 5 kg/m2 ; AHI, 35 ± 26 events/hr. AHI was associated with all anthropometrics except weight, height and HC. The best univariate predictor was WHR, which accounted for 15% of AHI variance. The simplest model (age + BMI) accounted for 9%, which increased to 20% when applying more complex measurements (age + BMI + NC + WC + HC). The explanatory capacity did not change significantly when applying a simpler model (age + WHR + NC, 19%). In this female morbidly obese cohort, anthropometrics explained one-fifth of AHI variability. WHR is the best univariate parameter and models including waist and neck data provide more information than BMI when explaining AHI variability. Thus, even in young women with extreme obesity, OSA seems to be linked to a specific central-obesity phenotype rather than to a whole-obesity pattern.

BACKGROUND: Four commercially available intragastric balloons have been used for the management of obesity and underwent randomized controlled trials (RCTs), and we aimed to compare them using a network meta-analysis approach. METHODS: Several databases were queried from inception to May 26, 2017, and we included RCTs enrolling patients treated with Orbera, Heliosphere, ReShape Duo, and Obalon compared with another balloon, sham, or open-label control group. Two investigators independently abstracted data. A random effects frequentist network meta-analysis and relative ranking of agents using surface under the cumulative ranking probabilities were performed. RESULTS: We included 15 trials at low risk of bias (only two were head-to-head). Compared to control groups, the two fluid-filled devices were associated with significant outcome (% total body weight loss) at 6 months: Orbera, 6.72% (95% CI, 5.55, 7.89) and ReShape Duo 4% (95% CI 2.69, 5.31). Only one of the two gas-filled devices was associated with significant outcome at 6 months: Obalon 3.3% (95% CI 2.30, 4.30), and not the second: Heliosphere 6.71% (95% CI - 0.82, 14.23). Fluid-filled devices had the highest likelihood of superiority in achieving the outcome at 6 months (96.8%) and at 12 months (96.6%). The quality of evidence was high for comparisons against control. CONCLUSIONS: Fluid-filled balloons are more likely to produce weight loss compared to gas-filled balloons or lifestyle intervention. However, they may be associated with a higher rate of intolerance and early removal. This information will aid clinicians in device selection and engaging patients in shared decision-making.

PURPOSE: The objective of this post-market study was to evaluate long-term safety and efficacy of aspiration therapy (AT) in a clinical setting in five European clinics. MATERIALS AND METHODS: The AspireAssist® System (Aspire Bariatrics, Inc. King of Prussia, PA) is an endoscopic weight loss therapy utilizing a customized percutaneous endoscopic gastrostomy tube and an external device to aspirate approximately 30% of ingested calories after a meal, in conjunction with lifestyle counseling. A total of 201 participants, with body mass index (BMI) of 35.0-70.0 kg/m2, were enrolled in this study from June 2012 to December 2016. Mean baseline BMI was 43.6 ± 7.2 kg/m2. RESULTS: Mean percent total weight loss at 1, 2, 3, and 4 years, respectively, was 18.2% ± 9.4% (n/N = 155/173), 19.8% ± 11.3% (n/N = 82/114), 21.3% ± 9.6% (n/N = 24/43), and 19.2% ± 13.1% (n/N = 12/30), where n is the number of measured participants and N is the number of participants in the absence of withdrawals or lost to follow-up. Clinically significant reductions in glycated hemoglobin (HbA1C), triglycerides, and blood pressure were observed. For participants with diabetes, HbA1C decreased by 1% (P < 0.0001) from 7.8% at baseline to 6.8% at 1 year. The only serious complications were buried bumpers, experienced by seven participants and resolved by removal/replacement of the A-Tube, and a single case of peritonitis, resolved with a 2-day course of intravenous antibiotics. CONCLUSION: This study establishes that aspiration therapy is a safe, effective, and durable weight loss therapy in people with classes II and III obesity in a clinical setting. TRIAL REGISTRATION: ISRCTN 49958132.

BACKGROUND & AIMS: Reshape Duo is a saline-filled dual, integrated intragastric balloon (IGB) approved by the Food and Drug Administration for weight loss in patients with obesity. In a prospective, randomized trial, obese patients who received the balloon had significantly greater percent excess weight loss (%EWL) compared with patients treated with diet and exercise alone. However, there are limited data on the real-world efficacy of the Reshape balloon. METHODS: We performed a retrospective study of data collected from 2 academic centers and 5 private practices in which all patients paid for the IGB and follow-up visits out of pocket. The IGB was removed after 6 months. We collected data (demographic, medical, and laboratory) from 202 adults (mean age 47.8 ± 10.8 years; 83% female) with a baseline mean body mass index of 36.8 + 8.4 kg/m2 who had IGB insertion for weight loss therapy, along with counselling on lifestyle modifications focused on diet and exercise. Primary outcomes were percent total body weight loss (%TBWL) and %EWL at 1, 3, 6, 9, and 12 months after the procedure. RESULTS: Mean %TBWL at 1, 3, 6, 9 and 12 months was 4.8 ± 2.4%, 8.8 ± 4.3%, 11.4 ± 6.7%, 13.3 ± 7.8%, and 14.7 ± 11.8%, respectively. Data were available from 101 patients at 6 months and 12 patients at 12 months; 60.4% of patients achieved more than 10% TBWL and 55.4% had more than 25% EWL. Seventeen patients (8.4%) had esophageal tears during balloon insertion, with no intervention required. Thirteen patients (6.4%) had their IGB removed before the end of the 6-month treatment period. Nausea, vomiting, and abdominal pain were the most common adverse effects, occurring in 149 (73.8%), 99 (49%), and 51 (25.2%) patients. In one patient, the IGB migrated distally leading to small intestinal obstruction requiring surgical removal. CONCLUSION: In a retrospective analysis of real-world patients who received the Reshape Duo IGB, we found it to be a safe and efficacious endoscopic method for producing weight loss, with most patients achieving greater than 10% TBWL at 6 months.

BACKGROUND & AIMS: The Orbera intragastric balloon (OIB) is a single fluid-filled intragastric balloon approved for the induction of weight loss and treatment of obesity. However, little is known about the effectiveness and safety of the OIB outside clinical trials, and since approval, the Food and Drug Administration has issued warnings to health care providers about risk of balloon hyperinflation requiring early removal, pancreatitis, and death. We analyzed data on patients who have received the OIB since its approval to determine its safety, effectiveness, and tolerance in real-world clinical settings. METHODS: We performed a postregulatory approval study of the safety and efficacy of the OIB, and factors associated with intolerance and response. We collected data from the Mayo Clinic's database of patient demographics, outcomes of OIB placement (weight loss, weight-related comorbidities), technical aspects of insertion and removal, and adverse events associated with the device and/or procedure, from 8 centers (3 academic, 5 private, 4 surgeons, and 4 gastroenterologists). Our final analysis comprised 321 patients (mean age, 48.1 ± 11.9 y; 80% female; baseline body mass index, 37.6 ± 6.9). Exploratory multivariable linear and logistic regression analyses were performed to identify predictors of success and early balloon removal. Primary effectiveness outcomes were percentage of total body weight lost at 3, 6, and 9 months. Primary and secondary safety outcomes were rates of early balloon removal, periprocedural complications, dehydration episodes requiring intravenous infusion, balloon migration, balloon deflation or hyperinflation, pancreatitis, or other complications. RESULTS: Four patients had contraindications for placement at the time of endoscopy. The balloon was safely removed in all instances with an early removal rate (before 6 months) in 16.7% of patients, at a median of 8 weeks after placement (range, 1-6 mo). Use of selective serotonin or serotonin-norepinephrine re-uptake inhibitors at the time of balloon placement was associated with increased odds of removal before 6 months (odds ratio, 3.92; 95% CI, 1.24-12.41). Total body weight lost at 3 months was 8.5% ± 4.9% (n = 204), at 6 months was 11.8% ± 7.5% (n = 199), and at 9 months was 13.3% ± 10% (n = 47). At 6 months, total body weight losses of 5%, 10%, and 15% were achieved by 88%, 62%, and 31% of patients, respectively. Number of follow-up visits and weight loss at 3 months were associated with increased weight loss at 6 months (ß = 0.5 and 1.2, respectively) (P < .05). Mean levels of cholesterol, triglycerides, low-density lipoprotein, and hemoglobin A1c, as well as systolic and diastolic blood pressure, were significantly improved at 6 months after OIB placement (P < .05). CONCLUSIONS: In an analysis of a database of patients who received endoscopic placement of the OIB, we found it to be safe, effective at inducing weight loss, and to reduce obesity-related comorbidities in a real-world clinical population. Rates of early removal (before 8 weeks) did not differ significantly between clinical trials and the real-world population, but were affected by use of medications.

Endoscopic bariatric therapies are predicted to become much more widely used in North America for obese patients who are not candidates for bariatric surgery. Of all the endoscopic bariatric therapies, intragastric balloons (IGBs) have the greatest amount of clinical experience and published data supporting their use. Three IGBs are FDA approved and are now commercially available in the USA (Orbera, ReShape Duo, and Obalon) with others likely soon to follow. They are generally indicated for patients whose BMI ranges from 30 to 40 mg/kg2 and who have failed to lose weight with diet and exercise. IGBs have been shown to be safe, effective, and relatively straightforward to place and remove. Accommodative symptoms commonly occur within the initial weeks post-placement; however, major complications are rare. Gastric ulceration can occur in up to 10% of patients, while balloon deflation with migration and bowel obstruction occurs in <1% of patients. The effectiveness of the Orbera and ReShape Duo IGBs ranges from 25 to 50% EWL (excess weight loss) after 6 months of therapy. The use of IGBs is likely to grow dramatically in the USA, and gastroenterologists and endoscopists should be familiar with their indications/contraindications, efficacy, placement/removal, and complications.

La cirugía bariátrica denota complejidad y no está libre de complicaciones. Estas son de causa multfactorial y dependen de factores intrínsecos delpaciente o bien de habilidades técnicas y experiencia del cirujano. En general cualquier complicación puede catalogarse como temprana (< 30 días) otardía (> 30 días) según el tempo de aparición luego de la cirugía.La banda gástrica es uno de los procedimientos bariátricos mas realizados pero con un alto índice de complicaciones, entre las tardías destacan deslizamiento,migración y problemas del reservorio. El Bypass gástrico contnua teniendo mucha fabilidad en cuanto a control de la obesidad pero presentacomplicaciones como las hernias internas, estenosis y úlceras de anastomosis, y fstulas gastro gástricas entre otras, cuyo diagnóstco y manejo precozes importante.La gastrectomía vertcal en manga ha ganado terreno en los últmos años por sus buenos resultados pero también por su baja tasa de complicaciones amediano y largo plazo, dentro de sus problemas tardíos descritos están estenosis, dilatación gástrica y cierta relación con aparición o exacerbación derefujo gastroesofágico. Otro procedimiento bariátrico poco utlizado en la actualidad es la derivación biliopancreátca por su múltples complicacionestardías.La colelitasis es un problema comúnmente documentado luego de cirugía bariátrica en tasas de 30 a 52%, cuya resolución quirúrgica es importantepara evitar complicaciones mayores.
Bariatric surgery denotes complexity and is not free of complicatons. These are multfactorial and depend on intrinsic patent factors or technical skillsand experience of the surgeon. In general any complicatons can be classifed as early (<30 days) or late (> 30 days) as the tme of onset afer surgery.Gastric banding is one of the most performed bariatric procedures but with a high rate of complicatons; late complicatons as slipping, migraton andreservoir problems have been documented. Gastric bypass contnues to have much reliability as to control obesity but has complicatons such as internalhernias, anastomotc strictures and ulcers and gastro gastric fstulas among others, whose diagnosis and early management is important.Sleeve gastrectomy gained ground in recent years for its good results but also for its low complicaton rate in the medium and long term. The lateproblems described are stenosis, gastric dilataton and some relaton to onset or exacerbaton of gastro esophageal refux. Another bariatric procedureused actually is the biliopancreatc diversion but for his multple late complicatons it is less performed.Cholelithiasis is a problem commonly documented afer bariatric surgery rates from 30 to 52%, the surgical resoluton is important to prevent furthercomplicatons.

Obesity is recently considered as the twentieth first century epidemy. An excessive accumulation of adipocytes that constitute metabolically active tissue, plays an important role in lipid and carbohydrate metabolism. In the morbidly obese population dyslipidemia is common. AIM OF OUR STUDY: To determine the content of total cholesterol (TC), HDL-cholesterol (HDL), LDL-cholesterol (LDL) and triacylglicerol (TG) in obese subjects treated with the Bioenterics Intragastric Balloon (BIB). MATERIAL AND METHODS: BIB was placement for 6 months in 21 obese patients, mean age 40 (21-60), with BMI 473 +/- 5.7 kg/m2. The control group consisted of 15 morbidly obese patients treated conservatively. Plasma lipid concentration were assessed by the enzymatic methods. RESULTS: No major complications have been noted in patients with BIB. However, nearly all patients complained of discomfort, nausea and vomiting for the first few days. Over a 6-month-period, a reduction in body mass in the BIB group was 17.1 +/- 8.0 kg as compared to 3.2 +/- 6.4 kg in the control group (p = 0.00003). The biggest reduction in body mass was observed during first month. After one month, total cholesterol (TC) decreased by 17.6% (p < 0.001), triacylglycerol (TG) decreased by 25.5% (p = 0.01), low-density lipoprotein cholesterol (LDL) decreased by 27.5% (p < 0.001). In the control group, the corresponding levels of TC, TG and LDL remained unchanged. The level of HDL increased in both group. CONCLUSIONS: In patients with morbid obesity treated with BIB, weight loss is accompanied by a decrease in concentration TC, LDL and TG and increase in plasma HDL. The reduction of lipid concentration in blood serum may cut down cholesterol-lowering therapy and diminish the risk for development of coronary heart disease.
