[PMID: 38877371 DOI: 10.1007/s11695-024-07361-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Revised: 06/06/2024] [Accepted: 06/07/2024] [Indexed: 06/16/2024]
Abstract
PURPOSE Although bariatric surgery is associated with a decrease in obesity complications, it may affect the children's growth by a maternal nutritional deficiency. This study was conducted to assess the effect of maternal bariatric surgery on offspring anthropometry. MATERIALS AND METHODS In a mixed cohort, anthropometric status of children aged 5 years or less born to mothers with a history of bariatric surgery was compared with a control group consists of peers born to mothers with obesity but without bariatric surgery. Anthropometric indices including crude and quantile values for BMI, weight, height, and head circumference at birth and the first 5 years of life were measured. Then, the adjusted effect of maternal surgical history on anthropometric status was estimated by linear regression. RESULTS From a total of 56 children, 28 born to mothers with a history of bariatric surgery, and 28 born to mothers with obesity but without bariatric surgery. At birth, weight (2915 vs 3225 g) and BMI (11.72 vs 12.94 kg/m2) were lower in the group with maternal bariatric surgery than in the control group (P = 0.02 and P = 0.03, respectively), although after regression adjustment, there was only a significant difference between the two groups in height for age value in children less than 5 years old (B = 0.872, P-value = 0.001). CONCLUSION Bariatric surgery with decrease of weight indices at birth has a probable influence on growth and development in next years. Therefore, it is recommended further studies to identify unknown effect of types of preconception surgical procedures on childhood outcomes.

BMC Surg 2024; 24:156. [PMID: 38755612 PMCID: PMC11097460 DOI: 10.1186/s12893-024-02438-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2024] [Accepted: 05/06/2024] [Indexed: 05/18/2024] Open
Abstract
PURPOSE Hypoalbuminemia and anemia are commonly observed indications for one anastomosis gastric bypass (OAGB) reversal and remain significant concerns following the procedure. Sufficient common channel limb length (CCLL) is crucial to minimize nutritional complications. However, limited literature exists regarding the impact of CCLL on OAGB outcomes. This study aimed to assess the effect of CCLL on weight loss and nutritional status in patients who underwent OAGB. METHODS A prospective cohort study was conducted from August 2021 to July 2022, involving 64 patients with a body mass index of 40-50 kg/m2. The standardized length of the biliopancreatic limb (BPLL) for all patients in this study was set at 175 cm. Additionally, the measurement of the common channel limb length (CCLL) was performed consistently by the same surgeon for all included patients. RESULTS The mean age and BMI of the patients were 39.91 ± 10.03 years and 43.13 ± 2.43 kg/m2, respectively, at the time of surgery. There was a statistically significant negative correlation between CCLL and percent total weight loss (%TWL) at the 12-month mark after OAGB (P = 0.02). Hypoalbuminemia was observed in one patient (1.6%), while anemia was present in 17 patients (26.6%) at the one-year follow-up. Statistical analysis revealed no significant difference in the incidence of anemia and hypoalbuminemia between patients with CCLL < 4 m and those with CCLL ≥ 4 m. CONCLUSION A CCLL of 4 m does not appear to completely prevent nutritional complications following OAGB. However, maintaining a CCLL of at least 4 m may be associated with a reduced risk of postoperative nutritional deficiencies.

The Impact of Metabolic and Bariatric Surgery on Apo B100 Levels in Individuals with high BMI: A Multi-Centric Prospective Cohort Study. Obes Surg 2024:10.1007/s11695-024-07258-6. [PMID: 38744799 DOI: 10.1007/s11695-024-07258-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2024] [Revised: 04/19/2024] [Accepted: 04/24/2024] [Indexed: 05/16/2024]
Abstract
BACKGROUND Metabolic and Bariatric surgery (MBS) leads to significant weight loss and improvements in obesity-related comorbidities. However, the impact of MBS on Apolipoprotein B100 (Apo-B100) regulation is unclear. Apo-B100 is essential for the assembly and secretion of serum lipoprotein particles. Elevated levels of these factors can accelerate the development of atherosclerotic plaques in blood vessels. This study aimed to evaluate changes in Apo-B100 levels following MBS. METHODS 121 participants from the Iranian National Obesity and Metabolic Surgery Database (INOSD) underwent Laparoscopic Sleeve Gastrectomy (LSG) (n = 43), One-Anastomosis Gastric Bypass (OAGB) (n = 70) or Roux-en-Y Gastric Bypass (RYGB) (n = 8). Serum Apo-B100, lipid profiles, liver enzymes, and fasting glucose were measured preoperatively and six months postoperatively. RESULTS Apo-B100 levels significantly decreased from 94.63 ± 14.35 mg/dL preoperatively to 62.97 ± 19.97 mg/dL after six months (p < 0.01), alongside reductions in total cholesterol, triglycerides, LDL, VLDL, AST, and ALT (p < 0.05). Greater Apo-B100 reductions occurred in non-diabetics versus people with diabetes (p = 0.012) and strongly correlated with baseline Apo-B100 (r = 0.455, p < 0.01) and LDL levels (r = 0.413, p < 0.01). However, surgery type did not impact Apo-B100 changes in multivariate analysis (p > 0.05). CONCLUSION Bariatric surgery leads to a significant reduction in Apo-B100 levels and improvements in lipid profiles and liver enzymes, indicating a positive impact on dyslipidemia and cardiovascular risk in individuals with high BMI.

Abstract
PURPOSE Gastroesophageal reflux disease (GERD) is an issue after one anastomosis gastric bypass (OAGB) and modification of OAGB with adding an anti-reflux system may decrease the incidence of postoperative GERD. This study aimed to compare the efficacy of the anti-reflux mechanism to treat preoperative GERD and prevent de novo GERD. METHODS A prospective randomized clinical trial study was conducted on patients with a body mass index of 40 and more from August 2020 to February 2022. Patients undergoing one anastomosis gastric bypass with and without anti-reflux sutures (groups A and B, respectively). These patients had follow-ups for one year after the surgery. GERD symptoms were assessed in all the patients using the GERD symptom questionnaire. RESULTS The mean age was 39.5 ± 9.8 years and 40.7 ± 10.2 years in groups A and B respectively. GERD symptoms remission occurred in 76.5% and 68.4% of patients in groups A and B, respectively. The incidence of de novo GERD symptoms was lower in group A, compared to group B (6.2% and 16.1% in groups A and B respectively), without any statistically significant difference (p-value: 0.239). CONCLUSION GERD symptoms and de novo GERD after OAGB seems to be under-reported after OAGB. This study suggests that applying an anti-reflux suture can decrease de novo GERD symptoms.

Comparative Analysis of Mortality Rates among Morbidly Obese Individuals: A Study of Patients Undergoing Bariatric Surgery, Nonsurgical Morbidly Obese Individuals, and the General Population. Obes Facts 2024:1-9. [PMID: 38657591 DOI: 10.1159/000538968] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2023] [Accepted: 04/15/2024] [Indexed: 04/26/2024] Open
Abstract
INTRODUCTION Mortality decreases following bariatric surgery. We explored the extent of the reduction and whether or not it reaches the general population level in a large cohort of patients with obesity. This study aimed to compare all-cause mortality between patients with obesity who undergo bariatric surgery and those who do not, with the general Iranian population during the same period. METHOD Data from Iran's National Obesity Surgery Database were used to establish a large cohort of patients registered between 2009 and 2019. The current vital status of the patients was determined by utilizing post-surgery follow-up data for those who underwent the operation. For patients without a surgery record, a predefined checklist was filled out through telephone interviews. Death data from the National General Registrar's office were obtained for all cohort members. RESULTS Of 13,313 cohort members, 12,915 were eligible for analysis. The median age at the first visit was 38 years, and 78% were women. 6,190 patients (47.9%) underwent bariatric surgery, and 6,725 patients (52.1%) were not yet operated on at the time of analysis. We observed 139 deaths during 53,880 person-years follow-ups. The median follow-ups for operated-on and not operated-on groups were 4 and 4.8 years. The mortality rates among nonoperated patients were 2.89 times higher (standardized mortality ratio [SMR] = 2.89, 95% CI: 2.36-3.53) than those in the general population, while in operated patients, the mortality rate decreased to 1.82 as high (SMR = 1.82, 95% CI: 1.34-2.46). CONCLUSION The risk of death has been diminished in the operated-on group. It still remains considerably higher than the risk in the general population.

Abstract
PURPOSE Metabolic and bariatric surgery (MBS) has been shown to enhance the quality of life (QoL) in individuals with obesity. The Bariatric Analysis and Reporting Outcome System (BAROS) is a highly reliable scoring system utilized to assess weight loss, obesity-associated medical conditions, and QoL following MBS. This study aimed to assess the efficacy of sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and one anastomosis gastric bypass (OAGB) in improving health outcomes for individuals with severe obesity, employing the BAROS questionnaire. METHODS A retrospective study was conducted, enrolling 299 patients with a body mass index (BMI) of 40 or higher who had undergone primary MBS (RYGB, OAGB, or SG) and had a 5-year follow-up. Patients were evaluated using the BAROS scoring system, which included measures of % excess weight loss (%EWL), improvement and remission of obesity-related medical problems, and postoperative short-term and long-term complications. RESULTS The mean age and pre-op BMI of the patients was 39.4 ± 9.4 years and 44.6± 6.5 kg/m2, respectively. The total BAROS score was significantly higher in patients who underwent OAGB compared to those who underwent RYGB and SG (P, 0.02). However, no significant differences were observed in other aspects of the BAROS score, such as QoL. CONCLUSION This study demonstrated that all three common metabolic and bariatric surgical procedures (SG, RYGB, and OAGB) significantly improved the QoL after surgery. Furthermore, patients who underwent OAGB had a significantly higher total BAROS score at the 5-year follow-up compared to those who underwent RYGB and SG.

Abstract
PURPOSE Helicobacter pylori (HP) is the most common human infection that has affected up to 50% of the population worldwide. The relationship between HP eradication and weight loss is under debate. The present study aimed to compare weight loss outcomes after Roux-en-Y gastric bypass (RYGB) in HP-negative (HP-) and HP-eradicated (HPe) patients during five years follow-ups. METHODS This retrospective cohort study was conducted on 305 patients aged 18 and more with severe obesity, who underwent primary RYGB from February 2014 to November 2017. The HP-negative and HP-eradicated patients were evaluated for weight loss outcomes during five years follow-ups. RESULTS Patients' mean age, mean weight, and mean body mass index were 38.78 ± 9.9, 114.8 ± 13.6, and 43.37 ± 2.55, respectively. 27.2% of patients who were HP-positive were treated before RYGB. There was no significant difference between the HP- and HPe patients in terms of total weight loss percent (%TWL), 12 to 60 months after RYGB. Excess weight loss percent (%EWL) was higher in HPe patients compared to HP- patients (P = 0.04) at 12-month after RYGB. However, there was no difference in %EWL between these two groups of patients, 36 and 60 months after RYGB. CONCLUSION The results of the present study showed that TWL% had no significant difference in HP- and HPe groups during five years follow-ups after RYGB. The %EWL was higher in HPe patients only at 12 months after RYGB and the difference did not persist over time.

Abstract
BACKGROUND Patients with class I obesity may need metabolic and bariatric surgery (MBS) in the presence of obesity-associated medical problems, but MBS in this class of obesity is under debate. This study aimed to investigate the efficacy and safety of MBS in patients with class I obesity. METHODS AND MATERIALS This study was a historical cohort carried out on 112 patients with class I obesity with body mass index (BMI) of 30-35 kg/m2 with a 24-month follow-up underwent MBS at Rasoul-e-Akram Hospital. The required data were extracted through the Iran National Obesity Surgery Database. The data required for the study consisted of demographic information such as age, gender, and obesity-associated medical problems like type-2 diabetes mellitus (T2DM), hypertension, obstructive sleep apnea, and dyslipidemia before surgery, 6, 12, and 24 months after surgery. RESULTS Mean age of the patients was 38.10 ± 10.04 years; mean BMI was 32.96 ± 1.35 kg/m2 and 83.9% (n = 94) of patients were female. Out of 18 patients with T2DM, 11 patients (61.11%) had complete remission and seven patients (38.88%) had partial remission. Obstructive sleep apnea, hypertension, dyslipidemia, and gastroesophageal reflux disease were observed in 18 (16.07%), 23 (20.53%), 43 (38.39%), and 13 patients (11.60%) before surgery and resolved at 24-month follow-up. Post-operative complications during the 24-month follow-up were checked to assess safety and there were no De novo gastroesophageal reflux disease, intolerance, leakage, pulmonary thromboembolism, deep vein thrombosis, incisional hernia, hypoalbuminemia (Albumin < 3.5 g/dl), excessive weight loss (BMI < 18.5 kg/m2) at any time during 24-months follow-ups and mortality. Early complications occurred as splenic injury in one case (0.89%), wound infection in one patient (0.89%), and extra-luminal bleeding in 10 (8.92%) after surgery, without any mortality. CONCLUSION MBS is safe and effective in class I obesity and can be considered in selected patients with obesity-associated medical problems.

Did the COVID-19 pandemic change the weight reduction in patients with obesity after bariatric surgery? BMC Public Health 2023; 23:1975. [PMID: 37821928 PMCID: PMC10568805 DOI: 10.1186/s12889-023-16837-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Accepted: 09/26/2023] [Indexed: 10/13/2023] Open
Abstract
BACKGROUND The COVID-19 pandemic has significantly impacted healthcare services worldwide, including bariatric surgery. There is a concern that the pandemic-induced stay-at-home orders and social restrictions may negatively affect weight reduction outcomes post-bariatric surgery. This study aimed to examine the impact of the COVID-19 on weight loss up to six months after three types of bariatric surgeries including One-Anastomosis Gastric Bypass (OAGB), RY Gastric Bypass (RYGB), and Sleeve Gastrectomy (SG) before and two time periods during the COVID-19 pandemic. METHODS We conducted a retrospective study using data from a comprehensive database of bariatric surgery patients in Iran. We recruited 882 patients who underwent bariatric surgery from the initiation of COVID-19 to 6 months before public vaccination (Time period 3); among them, 311 patients underwent surgery in the first six months of the pandemic (Time period 2). These patients were compared with 1368 ones in the control group who completed their 6 months follow-up before the pandemic. The study compared the BMI reduction, excess weight loss (EWL), and total weight loss (TWL) outcomes between these groups using Generalized Estimating Equations (GEE) with gamma distribution to adjust for factors that were unevenly distributed across the groups. RESULTS The age of participants in time periods 2 and 3 had a mean (standard deviation) of 38.97 (10.99) and 38.84 (10.71), respectively. In all groups, the majority of patients were females, accounting for 76.02%, 71.06%, and 75.74% for the control group and time periods 2 and 3, respectively. There was no significant difference between the groups in terms of weight reduction, as measured by BMI reduction, EWL, and TWL (related P values: 0.283, 0.465 and 0.169). Regression analysis indicated that higher baseline BMI values were associated with greater BMI reduction (0.04, 95% CI: 0.03-0.05), but this did not translate to higher EWL or TWL. Males showed greater BMI reduction (0.33, 95% CI: 0.18-0.49) and EWL (1.58, 95% CI: 0.79-2.37) than females, while females achieved higher TWL compared to males. Among different types of surgery, the OAGB resulted in more weight reduction among patients in the study. CONCLUSION In conclusion, our study reveals that bariatric surgery remains effective for weight reduction during the first 6 months of the pandemic in Iran. Implementation of pandemic protocols ensures comparable efficacy to non-pandemic times. However, caution is needed in generalizing results beyond our specific context due to study limitations. Further research is essential to comprehensively assess the pandemic's broader impact on bariatric surgery outcomes under varying conditions.

Abstract
BACKGROUND Childhood obesity is an important worldwide issue of serious medical and social concern. One anastomosis gastric bypass (OAGB) is an approved, effective, and long-lasting procedure for weight loss and the remission of obesity-associated medical problems in the adult patients, but its efficacy and safety in children and adolescents are still on debate. This study aimed to evaluate safety and efficacy of OAGB compare to SG and RYGB during a 5-year follow-up. METHODS A retrospective cohort study on children and adolescents with severe obesity who underwent primary OAGB, sleeve gastrectomy (SG), and Roux-e-Y gastric bypass (RYGB) at an academic hospital, between March 2016 and December 2020. RESULTS Two hundred twenty-eight patients with 24 to 60 months of follow-up including 107 SG, 37 RYGB, and 84 OAGB were included in the final analysis. The mean age, preoperative weight, and BMI were 15.71 ± 2.09 years (range, 9-18 years), 126.3 ± 22.0 kg (74.5-215 kg), and 45.1 ± 6.9 kg/ m2 (36.4-79.3 kg/m2), respectively. The mean of follow-up was 30.05 ± 19.98 months. The mean of ∆BMI was 30.2 ± 5.1, 30.0 ± 5.4, and 31.1 ± 6.8 at 12th, 36th, and 60th months postoperative. At the 60-month follow-up, there were statistically significant differences in ΔBMI between SG and OAGB and SG and RYGB. CONCLUSION OAGB is a safe and effective procedure for the treatment of obesity in children and adolescents in 24 to 60 months follow-ups.

Abstract
BACKGROUND AND AIMS Several studies have shown the association between obesity and sleep. Roux-en-Y gastric bypass (RYGB) surgery may improve sleep disturbances in patients with obesity by influencing a variety of factors. This study aims to evaluate the impact of bariatric surgery on sleep quality. METHODS Patients with severe obesity referred to the obesity clinic of a center from September 2019 to October 2021 were collected. The patients were divided into two groups, depending on whether they underwent RYGB surgery. Medical comorbidities and self-report questionnaires regarding sleep quality, anxiety, and depression were collected at baseline and 1-year follow-up. RESULTS 54 patients were included, including 25 in the bariatric surgery group and 29 in the control group. However, five patients in the RYGB surgery group and four patients in the control group were lost in the follow-up. Pittsburgh Sleep Quality Index (PSQI) was decreased from a mean of 7.7 to 3.8 in the bariatric surgery group (p-value<0.001). In contrast to the control group, the number of patients with obstructive sleep apnea was significantly reduced in the bariatric surgery group. CONCLUSIONS We showed a significant improvement in sleep quality following RYGB surgery. Obstructive sleep apnea, obesity/overweight, and depressive symptoms significantly improved in our study. There is a lack of a better understanding of the association between these factors and sleep quality following surgery. Therefore, further studies are recommended regarding this issue.

[PMID: 36947225 DOI: 10.1007/s00464-023-10011-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2023] [Accepted: 03/09/2023] [Indexed: 03/23/2023]
Abstract
PURPOSE Sleeve gastrectomy (SG) has gained worldwide popularity by surgeons due to acceptable results in weight loss and obesity-associated medical problems. Distance from the pylorus during antral resection in SG may be effective in decreasing the occurrence of gastroesophageal reflux disease (GERD). The aim of this study was to evaluate GERD symptoms and weight loss outcomes in two groups of SG patients with different start points of antral resection. METHODS This is a prospective cohort study on 220 patients who underwent SG between June 2019 and July 2021, aged 18 and above, BMI ≥ 40 kg/m2, or BMI > 35 kg/m2 with at least one obesity-associated medical problem. According to the start point of antral resection the patients were divided in two groups (group A: from 2 cm of pylorus and group B: from 4 cm of pylorus). Evaluation of GERD was performed using GerdQ questionnaire at 12-month follow up. RESULTS Mean age and BMI of all patients were 37.6 ± 10 year and 44.8 ± 5.7 kg/m2 at the time of SG. Totally 153(69.5%) of the patients were female. De novo GERD after 12 months in the groups A and B was found in 18 (20%) and 19 (21%) patients. TWL% at 12-month follow ups, were 33.9% and 32.5% in group A and B, respectively. CONCLUSION Antral resection's start point has no statistically significant effect on the excess and total weight loss indices, resolution of the obesity-related medical problems and De novo GERD between 2 and 4 cm start point for antral resection during SG.

Abstract
PURPOSE The present research was conducted to evaluate the effect of the severity of dumping syndrome (DS) on weight loss outcomes after Roux-en-Y gastric bypass (RYGB) in patients with class III obesity. METHODS The present retrospective cohort study used the dumping symptom rating scale (DSRS) to evaluate the severity of DS and its correlation with weight loss outcomes in 207 patients 1 year after their RYGB. The patients were assigned to group A with mild-to-moderate DS or group B with severe DS. RESULTS The mean age of the patients was 42.18 ± 10.46 years and their mean preoperative BMI 42.74 ± 5.59 kg/m2. The total weight loss percentage (%TWL) in group B was insignificantly higher than that in group A, but besides that was not significantly different in the two groups. CONCLUSION The present findings suggested insignificant relationships between the presence and severity of DS after RYGB and adequate postoperative weight loss.

Reasons for Preoperative Patient Attrition among Bariatric Surgery Candidates: Patients' Point of View. Obes Surg 2023; 33:492-497. [PMID: 36689143 PMCID: PMC9869823 DOI: 10.1007/s11695-022-06373-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 11/20/2022] [Accepted: 11/28/2022] [Indexed: 01/24/2023]
Abstract
PURPOSE Obesity has become a global health concern, associated with decreased quality of life and life expectancy. Although bariatric surgery has many benefits (e.g., substantial and durable weight loss, amelioration of comorbidities, and improvement in functionality), its patient attrition rate is relatively high. Therefore, we aim to assess the causes of withdrawal from our program. MATERIALS AND METHODS We interviewed patients who dropped out of our bariatric surgery program between January 2016 and December 2021. A total of 1999 patients were eligible for bariatric surgery during this period, and 255 patients withdrew from the program. We interviewed patients over the phone to find out the reason for withdrawal. We divided participants into two groups: dropouts before and during the COVID-19 pandemic. Several options explaining the reason for leaving the program were presented to the patients to choose from. RESULTS The number of patients who withdrew from the program before and during the COVID-19 pandemic was 135 (8.9%) and 120 (25.2%), respectively. Before the COVID-19 pandemic, most patients (49.1%) stated that the long waiting time was the cause of withdrawal. Even though during the COVID-19 pandemic, the main causes of attrition were the fear of contracting the disease and COVID-19 infection; the most common reason unrelated to COVID-19 was still the long preoperative preparation. CONCLUSION Long waiting time was the most common cause of patient attrition before bariatric surgery. To reduce the attrition rate, more studies should be conducted to find an optimized waiting time before bariatric surgery.

Abstract
PURPOSE Sleeve gastrectomy (SG) is the most common bariatric procedure worldwide. It has been reported that there is a strong association between SG and the development of gastroesophageal reflux disease (GERD) and Barrett's esophagus (BE). This study was conducted to evaluate esophagogastroduodenoscopy (EGD) findings in patients with a history of SG with more than 5-year follow-up. METHODS This is a retrospective cohort study of prospectively maintained database. Inclusion criteria included patients who underwent SG between April 2015 and March 2016, aged 18 and above, BMI ≥ 40 kg/m2. Patients with 5 years of follow-up were invited to take part in the study and underwent EGD and biopsy. RESULTS One hundred twenty-six patients were recruited with a mean age of 44.6 ± 11.1 years. After a 5-year follow-up, there were 31 (29.5%) patients with reflux esophagitis. The grades of GERD were A, B, and C in 16 (15.2), 12 (11.4), and 3 (2.9%) patients, respectively. Incidence of BE was 5.7% after 5 years from SG. There was a 16.6% lost to follow-up at 5 years after SG. CONCLUSION The diagnosis and severity of GERD and the search for BE justify endoscopic surveillance in all long-term post-sleeve patients, regardless of reflux symptoms.

Abstract
INTRODUCTION Multidisciplinary care after bariatric surgery is essential for long-term safety and optimal weight loss. However, many patients do not participate in routine postoperative follow-ups. We have explored the determinants of patients' adherence to scheduled follow-up visits after bariatric surgery. METHOD A retrospective cohort study was performed on patients who underwent bariatric surgery from 2009 to 2019. Cohort participants with a proportion of attendance above the median were compared with those below the median in the first-year post-operation and the period after that. We assumed that the contribution of each predefined session to the overall attendance at eligible sessions is not equal. We weighted each predefined session by the proportion of attendance of all cohort members scheduled for that session. We then calculated the proportion of attendance for each individual at each period. Discriminatory logistic regression was used to identify factors separating adherers from non-adherers. RESULTS We followed 5245 patients who underwent bariatric surgery for up to 10 years. The median follow-up was 2 years. Patients with the following characteristics were more likely to comply with the postoperative attendance schedule: female sex, older age, higher body mass index at the first visit, non-smoker, readmission after surgery, being operated in a general hospital, and one-anastomosis gastric bypass (OAGB) or Roux-en-Y gastric bypass (RYGB) surgery type. Comorbidities did not significantly affect patients' adherence to the predefined follow-up schedules. CONCLUSION Younger male smokers are more likely non-adherers. Patients with comorbidities are not at an increased risk of missing predefined postoperative follow-up visits.

Abstract
BACKGROUND We evaluated the relationship between comorbidities associated with obesity, body mass index (BMI), and development of intestinal metaplasia (IM) after vertical sleeve gastrectomy (VSG). MATERIALS AND METHODS All VSG specimens performed at an academic center between 2011 and 2018 were reviewed. All specimens underwent histopathologic assessment, while those with findings suspicious for IM underwent additional immunohistochemical work up. Baseline patient characteristics and demographic data were obtained from Iran National Obesity Surgery Database by retrospective review. RESULTS A total of 862 adult individuals underwent VSG during the study period and specimens were histopathologically examined. All patients had preoperative upper endoscopy. The most common histopathologic diagnosis was miscellaneous findings (57.8%) followed by no pathologic finding (36.7%). The minority of patients (5.5%) had IM. Although 40.5% of patients had positive Helicobacter pylori infection preoperatively, just 13.8% had still positive infection postoperatively. A significant association was found between IM and hypercholesterolemia (odds ratio: 1.95; 95% confidence interval: 1.1, 3.5). CONCLUSION This study found a correlation between histopathologic changes in patients with IM and hypercholesterolemia. Prospective research studies are recommended to further examine this correlation.

Abstract
In patients with BMI ≥ 50 kg/m2, it is difficult to select an appropriate procedure that can lead to optimum results. This study aims to evaluate mid-term weight loss outcomes in patients with BMI ≥ 50 kg/m2 following one anastomosis gastric bypass (OAGB) as a one-stage procedure. A prospective study was conducted on patients with BMI ≥ 50 kg/m2, aged 18 years and above who had undergone primary OAGB from January 2016 to February 2019 with at least two years follow-ups. A total of 197 patients with BMI ≥ 50 kg/m2 had underwent OAGB. The mean age was 38 years and the mean pre-operative BMI was 53.7 kg/m2. Mean EWL% were 63.7%, 67.8% and 66.2% at one, two and five years after OAGB respectively. The highest level of EWL% was 68.4%, which was achieved in the 18th month following OAGB. OAGB can be performed safely in patients with BMI ≥ 50 kg/m2 as a one-stage procedure with acceptable weight loss outcomes and remission of obesity associated medical problems.

Five-year outcomes of one anastomosis gastric bypass as conversional surgery following sleeve gastrectomy for weight loss failure. Sci Rep 2022; 12:10304. [PMID: 35717435 PMCID: PMC9206653 DOI: 10.1038/s41598-022-14633-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2022] [Accepted: 06/09/2022] [Indexed: 11/29/2022] Open
Abstract
The most accepted procedures as conversion for poor weight changes after sleeve gastrectomy (SG), are malabsorptive surgeries. This study was designed to evaluate the 5-year outcomes of One Anastomosis Gastric Bypass (OAGB) following SG due to weight loss failure and weight regain. From September 2014 to January 2017, totally 23 patients with a history of SG conversion to OAGB in terms of weight loss failure or weight regain who had completed their 5-year follow-ups were studied. Some obesity related co-morbidities containing type-2 diabetes (DM), hypertension (HTN), dyslipidemia, obstructive sleep apnea (OSA) and gastroesophageal reflux disease (GERD) were also investigated at 1, 2, 3 and 5 years after conversional surgery. All cases had remission/improvement in DM, DLP, HTN and OSA 1 year after conversional OAGB. Analysis showed statistically significant (P < 0.001) change in trend of BMI. Mean BMI before conversional surgery, at 1, 2, 3and 5 years were 46.3 ± 10.4, 34.5 ± 8.5, 34.1 ± 8.6, 35.7 ± 8.7 and 37.5 ± 11.6, respectively. Mean percent excess weight loss (%EWL) at 1, 2, 3 and 5 years was 51.6 ± 11.0, 52.9 ± 13.1, 45.5 ± 16.4 and 41.0 ± 18.0, respectively. Mean percent total weight loss (%TWL) at 1, 2, 3 and 5 years was 26.6 ± 5.9, 27.4 ± 7.2, 23.9 ± 9.2 and 20.9 ± 9.3, respectively. OAGB is an effective conversional procedure for insufficient weight loss and weight regain following failed SG and lead to satisfactory changes in obesity associated medical problems. The optimal weight loss results are obtained at 2-year follow-ups and these effects are then reduced.
