ABSTRACT Background: Obesity is a major health problem. One anastomosis-gastric bypass (OAGB) is a restrictive and malabsorptive weight loss surgery that carries the same characteristics of Roux-en-Y gastric bypass in its status as a weight loss mechanism; but, its results remain controversial. Aim: To describe the technique and outcomes of OAGB and its effects on weight loss and remission of comorbidities. Methods: Retrospective review of all patients who underwent OAGB procedure from January 2017 to January 2018. Patients’ baseline characteristics were recorded. The routine in follow-up were at 1, 3, 6 and 12 months. Results: A total of 51 patients underwent OAGB. The mean age was 43.8±9.3 years, mean weight was 125±31 and mean BMI was 55.8±12 kg/m2. With regard to comorbidities, 64.7% had type 2 diabetes mellitus (T2DM), 43.1% systemic arterial hypertension (SAH) and 51% dyslipidemia. The BMI decreased for 48.4±1.3 to 31±4.4 at 12 months (p=0.0001) and we obtained an average decreased of 65% excess weight loss (EWL) at 12 months of follow-up. There was improvement in the values of total cholesterol (CT) (p=0.348); triglycerides (TGC) (p=0.0001); LDL (p=0.06), HDL (p=0.029) and A1C (p=0.405). Remission of T2DM al 12 months follow-up after surgery was 57% (p=0.124), remission of SAH 37% (p=0.040) and remission of dyslipidemia of 43% (p=0.967). Conclusions: OAGB is a commonly performed and safe procedure. Short term results appear promising; however, long-term follow-up is necessary to evaluate complications and possible nutritional effects.

Bariatric surgery is an important therapy in weight loss. However, adherence to follow-up is critical and may be influenced by the patient-surgeon relationship. To test this hypothesis, bariatric surgical patients were surveyed from March 2013 to March 2015 via the National Association for Weight Loss Surgery webpage and social media outlets. Surgical outcomes and adherence to follow-up were collected, and aspects of the patient-surgeon relationship were assessed via the Likert scale. Correlations between survey item responses were calculated using Fisher's exact test, Student's t test, and Spearman's rho rank correlation. Three hundred twenty patients responded (n = 287 completed in entirety and n = 33 partially completed); 48 months was the median time to survey from operation (interquartile range, 22–84 months). Eighty-six per cent (n = 276) of patients rated their relationship with their operative surgeon as “average” to “very good.” Thirteen per cent (n = 43) rated their relationship as “poor” to “very poor.” Positive relationship with the operative surgeon and lack of complication were associated with adherence to follow-up ( P = 0.0001 and P = 0.002, respectively). The presence of complication did not affect the overall patient-surgeon relationship ( P = 0.5), although aspects of the patient-surgeon relationship were correlated to complications. There was no association between weight loss at one year and patient-surgeon relationship ( P = 0.6) or presence of complication ( P = 0.1). The findings of this study support the role of a positive patient-surgeon relationship in achieving long-term follow-up in post-bariatric surgical patients.

Abstract Purpose The treatment of people with severe obesity and BMI > 50 kg/m2 is challenging. The present study aims to evaluate the short and mid-term outcomes of one anastomosis gastric bypass (OAGB) with a biliopancreatic limb of 150 cm as a primary bariatric procedure to treat those people in a referral center for bariatric surgery. Material and Methods Data of patients who underwent OAGB for severe obesity with BMI > 50 kg/m2 between 2010 and 2017 were collected prospectively and analyzed retrospectively. Follow-up comprised clinical and biochemical assessment at 1, 3, 6, 12, 18, and 24 months postoperatively, and once a year thereafter. Results Overall, 245 patients underwent OAGB. Postoperative mortality was null, and early morbidity was observed in 14 (5.7%) patients. At 24 months, the percentage total weight loss (%TWL) was 43.2 ± 9, and percentage excess weight loss (%EWL) was 80 ± 15.7 (184 patients). At 60 months, %TWL was 41.9 ± 10.2, and %EWL was 78.1 ± 18.3 (79 patients). Conversion to Roux-en-Y gastric bypass was needed in three (1.2%) patients for reflux resistant to medical treatment. Six patients (2.4%) had reoperation for an internal hernia during follow-up. Anastomotic ulcers occurred in three (1.2%) patients. Only two patients (0.8%) underwent a second bariatric surgery for insufficient weight loss. Conclusion OAGB with a biliopancreatic limb of 150 cm is feasible and associated with sustained weight loss in the treatment of severe obesity with BMI > 50 kg/m2. Further randomized studies are needed to compare OAGB with other bariatric procedures in this setting. Graphical abstract

Abstract Background It is already known that Laparoscopic sleeve gastrectomy (LSG) has gained popularity as a stand-alone procedure with good short-term results for weight loss. However, in the long-term, weight regain is considered as a complication. Demand for secondary surgery is rising, partly for this reason, but through that study we try to discover the efficacy of conversion of failed sleeve gastrectomy to one anastomosis gastric bypass (OAGB) regarding weight loss and metabolic outcomes. Objective To asses the efficacy and safety of one anastomosis gastric bypass (OAGB) as a conversion surgery post Sleeve Gastrectomy failure as regard weight loss and metabolic outcomes. Patients and Methods This study is a retrospective cohort study which included 20 patients underwent one anastomosis gastric bypass at Ain-Shams University El-Demerdash Hospital, Cairo, Egypt and specialized bariatric center, Cairo, Egypt From February 2019 to July 2019 with 6 months of postoperative follow up till January 2019. Results In this study, we reviewed and analyzed the outcomes from the revision of the SG due to either inadequate weight loss or weight regain to one anastomosis gastric bypass (OAGB) with %EBWL of 6.65% at 1 month, 13.61 % at 3 months and 20.86% at 6 months. Conclusion OAGB appears to be an effective and safe therapeutic technique as a revisional surgery for failed primary SG with good short-term results for treating morbid obesity and its associated comorbidities with a significantly low rate of complications. However the EBWL was less than what is reported after primary OAGB weight. Multicenter studies with larger series of patients and longer term follow up after SG revisions to OAGB are warranted.

Introduction. Obesity is among the newest health matters that human beings are struggling with. Length of bypassed intestine is important in achievement of most weight loss and least nutritional and absorptive disorders. This study has aimed to assess short-term metabolic and nutritional effects of laparoscopic mini-gastric bypass/one anastomosis gastric bypass (MGB/OAGB) with a loop bypass length of 180 centimeters (cm) and compare these factors among patients with a body mass index (BMI) of 40–45 and 45–50 kilograms per square meter (kg/m2). Methods. 25 patients were put in group 1 (BMI = 40–45 kg/m2) and 25 patients in group 2 (BMI = 45–50 kg/m2). Patients’ BMI, postoperative weight, excess weight loss, and laboratory tests including fasting blood sugar (FBS), lipid profile, serum iron (Fe), ferritin, total iron-binding capacity (TIBC), 25-OH vitamin D, vitamin B12, liver function tests, and albumin were recorded preoperatively and within 3- and 6-month follow-up. Results. Weight loss and BMI reduction was significantly more in patients with higher BMI level (P=0.007), and excess weight loss was higher in patients with lower preoperative BMI level (P=0.007). Six-month follow-up showed statistically significant reduction in total cholesterol, total triglyceride, Fe, and vitamin B12 among patients with higher BMI level (P value <0.05). Conclusion. Based on this study, 180-cm intestinal bypassed length works for patients with a BMI level of 40–45 and 45–50 kg/m2, according to their significant decrease in weight, BMI, and improving glycolipid profile.

Abstract Purpose Since 2014, sleeve gastrectomy (SG) has been the most frequently performed bariatric-metabolic operation worldwide (2018: 386,096). There are only a few studies reporting a long-term follow-up (up to 11 years) available today. The aim of this study was to evaluate the long-term outcome of SG with a follow-up of at least 15 years regarding weight loss, remission of associated medical problems (AMP), conversions, and quality of life (QOL). Setting Multicenter cross-sectional study; university hospital. Methods This study includes all patients who had SG before 2005 at the participating bariatric centers. History of weight, AMP, conversions, and QOL were evaluated by interview at our bariatric center. Results Fifty-three patients met the inclusion criteria of a minimal follow-up of 15 years. Weight and body mass index at the time of the SG were 136.8kg and 48.7kg/m2. Twenty-six patients (49.1%) were converted to Roux-en-Y gastric bypass (RYGB) for weight regain and gastroesophageal reflux within the follow-up period. Total weight loss after 15 years was 31.5% in the non-converted group and 32.9% in the converted group. Remission rates of AMP and QOL were stable over the follow-up period. Conclusion Fifteen years after SG, a stable postoperative weight was observed at the cost of a high conversion rate. Patients converted to RYGB were able to achieve further weight loss and preserve good remission rates of AMP. SG in patients without the need of a conversion to another bariatric-metabolic procedure may be considered effective. Careful preoperative patient selection is mandatory when performing SG.
