RESUMEN
BACKGROUND: Obesity is associated with an increased incidence of at least 13 types of cancer. Although bariatric surgery has been associated with a reduced risk of hormonal cancers, data for non-hormonal cancers are scarce. The aim of this study was to evaluate the effect of bariatric surgery on the incidence of non-hormonal cancers. METHODS: Cochrane, Embase, PubMed, Scopus, and Web of Science were searched for articles between 1984 and 2018, following the PRISMA system. Meta-analysis was conducted using a random-effect model with subgroup analysis by procedure and cancer type. RESULTS: From 2526 studies screened, 15 were included. There were a total of 18 583 477 patients, 947 787 in the bariatric group and 17 635 690 in the control group. In comparison to the non-surgical group, the bariatric group had a lower incidence of cancer (OR .65 (95 per cent c.i. 0.53 to 0.80); P < 0.002). In the subgroup analysis, Roux-en-Y gastric bypass and sleeve gastrectomy were associated with decreased risk of developing cancer, while no difference was observed with adjustable gastric banding. When evaluated by cancer type, liver (OR 0.417 (95 per cent c.i. 0.323 to 0.538)), colorectal (OR 0.64 (95 per cent c.i. 0.49 to 0.84)), kidney and urinary tract cancer (OR 0.77 (95 per cent c.i. 0.72 to 0.83)), oesophageal (OR 0.60 (95 per cent c.i. 0.43 to 0.85)), and lung cancer (OR 0.796 (95 per cent c.i. 0.45 to 0.80)) also presented a lower cancer incidence in the bariatric group. CONCLUSION: Bariatric surgery is related to an almost 50 per cent reduction in the risk of non-hormonal cancers.

BACKGROUND: The single-anastomosis duodenoileal bypass with sleeve (SADI-S) is a relatively new bariatric procedure. In 2020, the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) started reporting outcomes for SADI-S. OBJECTIVES: We aimed to study the perioperative safety of SADI-S and compare it with other established bariatric procedures utilizing the MBSAQIP database. SETTING: Academic hospital, United States. METHODS: The 2020 MBSAQIP Participant Use File was used to evaluate SADI-S outcomes. We included SADI-S primary cases and excluded revisions and concurrent operations. A 5:1 propensity matched analysis (PMA) for 20 variables was performed to compare the outcomes of the SADI-S with the Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) and a 2:1 PMA to the biliopancreatic diversion with duodenal switch (BPD/DS). RESULTS: There were 255 primary SADI-S reported in 2020. After PMA, the only significant complications between the RYGB and SADI-S cohorts were Clavien-Dindo grade IVa and IVb (.1% and 1.4% versus 1.6% and 7.1%, respectively). SADI-S had more Clavien-Dindo grade II, IVa, and IVb complications than the SG cohort (1.3% versus 3.5%, P = .03; .2% versus 1.6%, P = 0; 1.% versus 7.1%, P = 0). When compared with BPD/DS, outcomes including readmission, reoperation, and intervention were not statistically significant. CONCLUSION: SADI-S, in its early adoption stage, has a higher incidence of perioperative complications than RYGB and SG. It has comparable 30-day outcomes to BPD/DS.

BACKGROUND: Roux-en-Y gastric bypass (RYGB) is a recognized, safe bariatric procedure with minimal complications. Marginal ulceration, however, remains a challenging problem with an incidence of 8-12%. While chronic NSAID use is an established risk factor for ulcer formation, aspirin use itself as a cause for marginal ulceration is still unclear. We aim to compare the rates of marginal ulceration in RYGB with and without aspirin use. METHODS: PubMed, ScienceDirect, Cochrane, Web of Science, and Google Scholar were searched for articles between 2008 and 2021 by two independent reviewers using the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA). The risk of bias was assessed using Newcastle-Ottawa Scale. Meta-analysis was conducted using a fixed-effect model. RESULTS: From 5324 studies screened, we included 3 studies. Two studies had a low risk of bias, and the other one presented a high risk of bias on the Newcastle-Ottawa Scale. We included 24,770 patients, 1911 with aspirin use and 22,859 without aspirin use. After the meta-analysis, patients who used aspirin had a significantly higher marginal ulceration rate than those who did not (OR = 1.33 [95% CI 1.08 to 1.63], P < .002; I2 = 39%). CONCLUSIONS: Aspirin use is associated with increased rates of marginal ulceration after RYGB.

BACKGROUND: Increased body mass index is a known risk factor for increased adverse events post-hysterectomy. The effects of previous bariatric surgery on outcomes after inpatient hysterectomy are not well elucidated. METHODS: The 2016 to 2018 National Inpatient Sample was queried for patients who underwent hysterectomy using International Classification of Disease 10 Procedure Codes before a matched analysis was performed to neutralize the potential confounding effects of comorbidities, body mass index, and age. Patients were divided into the following 2 groups: a case group (those with a history of bariatric surgery) and a control group (those without a history of bariatric surgery). Patients in the respective groups were matched 1:2 by age, Elixhauser comorbidity score, and body mass index at the time of surgery to analyze the risk of complications and mean length of stay. RESULTS: When 1:2 case-control matching was performed, women with a history of bariatric surgery (N = 595) had significantly fewer complications and decreased mean length of stay than the non-bariatric group (N = 1,190), even after controlling for body mass index at the time of hysterectomy. CONCLUSIONS: When matched for age, body mass index, and comorbidity score, patients with previous bariatric surgery had fewer complications and shorter lengths of stay than patients without a history of bariatric surgery. Women with a body mass index ≥40 kg/m2 requiring non-urgent hysterectomy may benefit from undergoing bariatric surgery first.

INTRODUCTION: Marginal ulcer (MU) is a common complication following Roux-en-Y gastric bypass (RYGB) with an incidence rate of up to 25%. Several studies have evaluated different risk factors associated with MU with inconsistent findings. In this meta-analysis, we aimed to identify the predictors of MU after RYGB. METHODS: A comprehensive literature search of PubMed, Embase, and Web of Science databases was conducted through April 2022. All studies that used a multivariate model to assess risk factors for MU after RYGB were included. Pooled odds ratios (OR) with 95% confidence intervals (CI) for risk factors reported in ≥ 3 studies were obtained within a random-effects model. RESULTS: Fourteen studies with 344,829 patients who underwent RYGB were included. Eleven different risk factors were analyzed. Meta-analysis demonstrated that Helicobacter pylori (HP) infection (OR 4.97 [2.24-10.99]), smoking (OR 2.50 [1.76-3.54]), and diabetes mellitus (OR 1.80 [1.15-2.80]), were significant predictors of MU. Increased age, body mass index, female gender, obstructive sleep apnea, hypertension, and alcohol use were not predictors of MU. There was a trend of an increased risk of MU associated with nonsteroidal anti-inflammatory drugs (OR 2.43 [0.72-8.21]) and a lower risk of MU with proton pump inhibitors use (OR 0.44 [0.11-2.11]). CONCLUSIONS: Smoking cessation, optimizing glycemic control, and eradication of HP infection reduce the risk of MU following RYGB. Recognition of predictors of MU after RYGB will allow physicians to identify high-risk patients, improve surgical outcomes, and reduce the risk of MU.

BACKGROUND: Gastrojejunal (GJ) anastomotic stenosis is a well-described complication after Roux-en-Y gastric bypass (RYGB); however, its impact on weight loss outcomes is not well elucidated. METHODS: We performed a retrospective cohort study of adult patients who underwent RYGB at our institution between 2008 and 2020. Propensity score matching was used to match 30 patients who developed GJ stenosis within the first 30 days post-RYGB with 120 control patients who did not develop this outcome. Short and long-term complications and mean percentage of total body weight loss (TWL) were recorded at 3 months, 6 months, 1 year, 2 years, 3 to 5 years, and 5 to 10 years postoperatively. Hierarchical linear regression modeling was used to analyze the association between early GJ stenosis and the mean percentage of TWL. RESULTS: Patients who developed early GJ stenosis had a 13.6% increase in the mean percentage of TWL when compared with controls in the hierarchical linear model [ P < 0.001 (95% CI: 5.7; 21.5)]. These patients were also more likely to present to an intravenous infusion center (70% vs 4%; P < 0.01), require readmission within 30 days (16.7% vs 2.5%; P < 0.01), and/or develop an internal hernia (23.3% vs 5.0%) postoperatively. CONCLUSIONS: Patients who develop early GJ stenosis after RYGB have a greater degree of long-term weight loss compared with patients who do not develop this complication. Although our findings support the key contribution that restrictive mechanisms play in maintaining weight loss after RYGB, GJ stenosis remains a complication associated with significant morbidity.

RESUMEN
INTRODUCTION: Severe adhesions in patients with previous abdominal operations may lead to a more challenging subsequent bariatric surgery [1, 2]. In this context, sleeve gastrectomy (SG) is the preferred weight loss surgery since it solely involves stomach resection (without bowel involvement) in one abdominal compartment. Additionally, SG has lower complication rates and a shorter operative time than other bariatric procedures [3, 4]. In this paper, we present a multimedia video of the management of a pancreatic leak after SG in a patient with multiple previous abdominal surgeries. MATERIALS AND METHODS: A 40-year-old female with a BMI of 36 kg/m2 and obesity-related comorbidities presented to our clinic for bariatric surgery evaluation. The patient had a history of a motor vehicle accident requiring a splenectomy, a liver laceration requiring packing and reoperation with an open abdomen for more than a month. This was followed by a hernia repair with component separation. Preoperative workup was completed, including an upper endoscopy (EGD) that was negative for esophagitis. The computed tomography (CT) scan showed an area in the left upper quadrant with no bowel loops adherent to the abdominal wall, thus a safer area for accessing the abdominal cavity (Fig. 1). The SG itself was challenging due to severe adhesions. These adhesions were between the bowel and abdominal wall, bowel and bowel, stomach and liver, and posterior stomach and pancreas (video). Once adhesiolysis was completed, the stomach was tailored successfully without intraoperative complications. The patient was discharged on postoperative day 1 with stable vitals and laboratory exams while tolerating a liquid diet. RESULTS: On postoperative day 2, the patient returned to the emergency department with abdominal pain, increased heart rate (120 per minute), and a white blood cell count (WBC) of 20,000 th/µL. The CT scan showed a left upper quadrant collection with no evidence of air or contrast extravasation from the sleeve, as shown in Fig. 2. The patient became unstable and did not respond adequately to resuscitation efforts. Due to the extensive dissection in the primary operation, we elected to perform a laparoscopic exploration on an urgent basis. A collection (dark fluid) was noted in the left upper quadrant, but no sleeve staple line leak was found even with the air leak test (Fig. 2). Drainage and wash out were completed, and 2 abdominal drains were placed. Although the patient had symptomatic improvement postoperatively, an EGD with fluoroscopy was repeated, and no leak was noted (Fig. 3). The fluid evaluation showed increased lipase suggesting the diagnosis of a pancreatic leak. A liquid diet was initiated, and the initial drain in the left upper quadrant was exchanged to a higher caliber one (16F 40 cm locking loop drain). The patient was stable and eventually discharged home on postoperative day 6. Eventually, the drains were draining less than 10 mL and then downsized and removed. The patient's weight loss journey continued afterward with no other complications at 10-month follow-up. CONCLUSIONS: Pancreatic leak is a rare but potentially severe complication after SG, especially in the difficult abdomen.

BACKGROUND: Severe obesity leads to a higher incidence of ventral hernias, thus complicating up to 8% of bariatric procedures. The optimal management of these hernias continues to be a controversial topic. We present our novel approach of utilizing an omental plug for concomitant ventral hernia management during metabolic surgery. METHODS: To prevent early bowel incarceration and obstruction during bariatric surgery, we sutured the omentum circumferentially to the edges of the hernia defect and to the hernia sac itself with absorbable suture. RESULTS: Four patients were managed with this novel omental plug technique. All patients were female. The mean age was 53 years (range 39 to 68 y), the mean body-mass index was 54.75 kg/m 2 (range 49 to 59 kg/m 2 ), and the mean follow-up was 4.6 months (range 1.5 to 6.5 mo). There were no hernia-related complications through the follow-up period. CONCLUSION: The omental plug technique is a feasible, inexpensive, and safe alternative for ventral hernias with the potential prevention of bowel incarceration during bariatric surgery. This approach allows deferring the definitive hernia repair for a later stage.

RESUMEN
BACKGROUND: The MBSAQIP has been used to evaluate risk and create risk models. Previous studies have determined what complications matter most. STUDY DESIGN: This study was a registry-based analysis of patients who underwent laparoscopic Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) between January 1, 2015, and December 31, 2019, at centers participating in MBSAQIP. Cases were identified using Current Procedural Terminology. Patients less than 18 years old were excluded. A chi-square test was used to assess differences in the prevalence of complications and effects across years. Using a multivariable Poisson regression model with a link log and robust estimation, prevalence ratio estimates and 95% CI were obtained. RESULTS: A total of 690,770 observations met the inclusion criteria. Mean (SD) age was 44.5 (±12.0) years, and mean (SD) BMI was 45.2 kg/m2 (±7.9). SG cases accounted for 73.45% of all observations. There was a significant relative reduction in readmissions, end-organ dysfunction, and all-cause mortality from 2015 to 2019 in the SG subgroup. There were also noticeable reductions in 30-day readmission, ICU admission, and end-organ dysfunction in the RYGB subgroup. For complications, bleeding, postoperative pneumonia, and stroke were significantly decreased in the RYGB subgroup, but only bleeding was significantly decreased in the SG subgroup during the 5-year study period. CONCLUSIONS: There has been a continuous improvement in several (but not all) outcomes through the years that the MBSAQIP has been collecting data. Different outcomes were reduced between the SG and RYGB subgroups, and the decrease in all-cause mortality was only noted in the SG subgroup.

BACKGROUND: Although revisions account for 17% of cases performed at bariatric centers of excellence, scarce data exists on whether index operation type influences outcomes after secondary operations. OBJECTIVE: We designed a study investigating the effect of primary procedure type on weight loss and perioperative complications after conversion bariatric surgery. SETTING: Tertiary Referral Hospital, USA. METHODS: We performed a retrospective review of patients undergoing conversion from sleeve gastrectomy (SG) or adjustable gastric band (AGB) to Roux-en-Y gastric bypass (RYGB) from 2009 to 2019. Post-operatively, we measured short- and medium-term complications and changes in body weight at various time points. Univariate and regression analyses were performed. RESULTS: Forty-two (SG) patients and 116 (AGB) patients underwent conversion to RYGB, most commonly for GERD (57.1%) in SG patients vs. weight regain (77.6%) in AGB patients. Mean pre-conversion BMI was 36.7 kg/m2 (SG) vs 43.8 kg/m2 (AGB). Mean time to conversion (months) was 52.9 (SG) vs 94.7 (AGB). Complication rate was 9.5% (SG) vs 6% (AGB) at 30 days (p = 0.48) and 31%(SG) vs 14.5% (AGB) (p = 0.02) at 2 years. Mean post conversion %TWL was 11.6% (SG) vs 24.6% (AGB) in patients with GERD/dysphagia (p = 0.014) and 20.7% (SG) vs 27.6% (AGB) in patients converted for weight-related reasons (p = 0.027) at 1 year. Overall mean %TWL was 13.2% (SG) vs 24.7% (AGB) at 2 years (p < 0.0035). CONCLUSION: After conversion to RYGB, patients with AGB experience better short- and medium-term weight loss than those with SG, even after accounting for conversion indications. SG to RYGB conversions have a higher resolution of reflux disease.

Background: Bariatric surgery is the most effective treatment for weight loss and obesity-related comorbidity resolution. However, bariatric surgery is not readily offered in specific populations due to the lack of data assessing its feasibility. This study intends to evaluate bariatric surgery in patients with an existing ostomy. Methods: We conducted a retrospective case series to assess the safety of Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) in patients with an end ileostomy or colostomy. Patient demographics, including obesity-related comorbidities, overall health status (American Society of Anesthesiologists score), and short-term complications (up to 30 days postoperatively), were analyzed. Results: Six patients were included. The mean age was 58 years, and the mean preoperative body mass index was 41.6. Three patients had a colostomy, and three had an ileostomy. The mean time of ostomy before surgery was 11 years. Two ostomies were due to trauma, two due to inflammatory bowel disease, one due to cancer, and one due to scleroderma. Mean postoperative follow-up was 23 months. No patient had increased ostomy output or infusion center visit. One patient had an ED visit, one had a short-term complication, and one had SG conversion to RYGB. Conclusions: Bariatric surgery is technically feasible in selected patients with ileostomy/colostomy with a reasonable short-term safety profile.
RESUMEN
BACKGROUND: Two large nationwide databases collect data on common operations in the United States. The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) collects bariatric data, whereas the National Quality Improvement Program (NSQIP) gathers details on a broader range of general surgical cases. OBJECTIVE: Evaluate the differences in rates of complications between both databases regarding Roux-en-Y gastric bypass and sleeve gastrectomy. SETTING: National databases, United States. METHODS: We evaluated the MBSAQIP and NSQIP from 2017 to 2019 using the procedure codes 43644 and 43775. Fifteen common complications were evaluated. Propensity-matched analyses (PMAs) were done to control for differences across databases. Significantly different variables after a PMA were included in multivariable models. The data were examined for differences between the 2 databases before and after the PMA, with and without adjustment for operation type. RESULTS: There were 483,361 cases reported in the MBSAQIP and 57,598 in the NSQIP. PMA matched 57,479 cases for each database. Seven complications were different, with higher rates reported in the NSQIP than in the MBSAQIP: myocardial infarction, sepsis, organ/space surgical site infections, deep vein thrombosis, urinary tract infections, pulmonary embolism, ventilator dependence >48 hours, and pneumonia. When adjusting for the procedure performed, sleeve gastrectomy in the NSQIP had higher rates of organ/space surgical site infections, deep vein thrombosis, sepsis, and death. Roux-en-Y gastric bypass in the NSQIP had higher rates of organ/space surgical site infections, ventilator dependence >48 hours, urinary tract infections, myocardial infarction, deep vein thrombosis, and sepsis. CONCLUSION: When compared with the MBSAQIP, the NSQIP reports higher rates of bariatric complications. Further studies are needed to confirm the reasons behind this.

BACKGROUND: Single anastomosis duodenal-ileal bypass with sleeve (SADI-S) is a novel bariatric surgery modified from the classic biliopancreatic diversion with duodenal switch (BPD-DS). These surgical modifications address most BPD-DS hurdles, but the risk of bile reflux may hinder SADI-S acceptance. We aimed to evaluate the event rate of bile reflux after SADI-S. METHODS: PubMed, ScienceDirect, Cochrane, Web of Science, and Google Scholar were used to search English articles between 2008 and 2021 by two independent reviewers using the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA). The risk of bias was assessed using Newcastle-Ottawa Scale and the JBI tool. Event rates were meta-analyzed using Comprehensive Meta-Analysis (CME) V3. RESULTS: Out of 3,027 studies analyzed, seven were included. Studies were published between 2010 and 2020. Six out of 7 studies were retrospective. Three studies had a low risk of bias, three studies had a moderate risk of bias, and one had a high risk of bias. The mean follow-up was 10.3 months. The total number of patients was 2,029, with 25 reports of bile reflux, resulting in an incidence of 1.23%, with an event rate of 0.016 (95% CI 0.004 to 0.055). CONCLUSIONS: Bile reflux has not been demonstrated to be problematic after SADI-S in this meta-analysis. Further long-term studies are needed.

INTRODUCTION: Endoscopic sleeve gastroplasty (ESG) is a novel endoscopic bariatric therapy that complements current medical and surgical therapeutic offerings for weight management and fills an unmet need. Few meta-analyses compared ESG to laparoscopic sleeve gastrectomy (LSG). However, these studies relied on indirect evidence derived from non-comparative studies. Comparative effectiveness data derived from direct comparative studies is needed. We performed a meta-analysis of studies that directly compared ESG with LSG. METHODS: A comprehensive search of PubMed, Embase, and Cochrane databases was conducted. Single-arm studies were excluded. Pooled mean difference (MD) and risk ratio (RR) with 95% confidence intervals (CIs) were obtained within a random-effect model. RESULTS: Seven studies with 6,775 patients (3,413 with ESG vs. 3,362 with LSG) were included. There were significant differences in 6-month (MD - 7.48; 95% CI - 10.44, - 4.52; P < 0.00001), 12-month (MD - 9.90; 95% CI - 10.59, - 9.22; P < 0.00001), and 24-month (MD - 7.63; 95% CI - 11.31, - 3.94; P < 0.0001) TBWL% favoring LSG over ESG. There was a trend toward lower incidence of adverse events with ESG compared to LSG but did not reach statistical significance (RR 0.51, 95% CI 0.23-1.11, P = 0.09). The incidence of new-onset gastroesophageal reflux disease (GERD) was significantly lower after ESG compared to LSG, 1.3% vs. 17.9%, respectively (RR 0.10, 95% CI 0.02-0.53, P = 0.006). CONCLUSIONS: ESG achieved clinically adequate but lower short- and mid-term weight loss when compared to LSG, with fewer adverse events, including GERD. Given the stomach-sparing nature of ESG and acceptable safety profile, it provides an acceptable alternative to LSG for patients with mild-to-moderate obesity.

INTRODUCTION: The aim of the study was to identify factors associated with the causes of in-hospital morbidity and mortality in an elderly Brazilian population due to osteoporotic hip fractures. METHOD: Retrospective cohort study involving a population over 60 years of age admitted to hospital due to osteoporotic hip fractures and followed up from hospitalization to outcome (discharge or mortality) from 2010 to 2018, in a public hospital in Brasília, the capital of Brazil. Multivariate analysis was performed using the Poisson regression model with a robust variance, observing the hierarchical model proposed and the receiver operating characteristic (ROC) curve to obtain the cutoff point for mortality incidence in relation the total length of hospital stay. Significance level was set as p < 0.05. The analyses were conducted using the SAS 9.4 software. RESULT: The mean hospital mortality rate among the 402 patients involved was 18.4%, and the associations made with the outcome mortality were per relevance: respiratory infection, age over 90 years, high preoperative cardiovascular risk, chronic obstructive pulmonary disease (COPD) as comorbidity, serum hemoglobin level ≤ 10 and other infections. Mortality also showed association with longer total length of hospital stay, as well as with prolonged postoperative period. CONCLUSION: Hip fractures in the elderly due to osteoporosis indicate a relationship between the sicker profile of the aging elderly population and the prevalence of chronic diseases strongly associated with in-hospital infections, contributing to increased mortality. There were fewer early interventions, and mortality was also associated with prolonged postoperative period. The aim of this study was not to compare independent variables with each other, but suggests the relationship between the presence of comorbidities, which predisposes to the development of infections, directly linked to mortality.

BACKGROUND: Diabetes mellitus type 2 (DM2) remission after bariatric surgery has long been reported in the medical literature. Glucocorticoid use is associated with weight gain and could theoretically affect diabetes remission post bariatric surgery. OBJECTIVES: The aim is to identify remission rates of DM2 among patients using glucocorticoids after bariatric surgery and assess long-term postsurgical follow-up. METHODS: A retrospective analysis was performed on patients who used glucocorticoids and underwent bariatric surgery at the Mayo Clinic between 2008 and 2020. Data were analyzed for 3-month, 6-month, 1-year, 2-year, and 5-year intervals for factors indicative of diabetes remission. RESULTS: Within our retrospective search, we identified 92 patients who were on any immunosuppressant medication before surgery. Of those, 22 patients had a diagnosis of DM2 while 18 of them were concurrently on glucocorticoids. Diabetes remission occurred in 11 of the 18 DM2 patients (61.11%). There was a statistically significant negative correlation between diabetes remission and combination therapy with glucocorticoids and tacrolimus (P=0.016); patients with a longer duration of DM2 diagnosis (P=0.024), and patients who used insulin three months after the procedure (P=0.001). However, percent total weight loss and the number of preoperative oral DM2 medications were not associated with worse outcomes. CONCLUSIONS: Patients who use systemic glucocorticoids are able to achieve diabetes remission after bariatric surgery. Concurrent therapy with tacrolimus is associated with worse remission outcomes.
