Bariatric surgery is an effective treatment for morbid obesity and its metabolic related comorbidities - Type II Diabetes, Hypertension and Hyperlipidaemia.1 However, the literature is scarce regarding the long-term outcome after bariatric surgery especially among multi-ethnic Asian populations. Considering the growing number of bariatric metabolic operations in Asia, we have attempted to provide a regional perspective on 5-year long-term clinical outcomes post bariatric surgery in Singapore. Between years 2010 to 2016, all bariatric operative cases consisted of 393 Laparoscopic Sleeve Gastrectomy (LSG), 125 Laparoscopic Roux-En-Y Gastric Bypass (RYGB) and 43 Laparoscopic Mini-gastric Bypass (MGB) were included...

Mini-gastric bypass/One-anastomosis gastric bypass (MGB-OAGB) is an effective bariatric technique for treating overweight and obesity, controlling and improving excess-weight-related comorbidities. Our study evaluated OAGB characteristics and resulting weight evolution, plus surgical success criteria based on various excess weight loss indicators. A prospective observational study of 100 patients undergoing OAGB performed by the same surgical team (two-year follow-up). Surgical characteristics were: surgery duration, associated complications, bowel loop length, hospital stay, and weight loss at 6 postoperative points...

With over 600 million people being obese, and given the scientific demonstration of the advantages of surgical treatment, bariatric surgery is on the rise. The promising long-term results in terms of weight loss, and particularly in relation to comorbidities and the control/cure rate, mean that the number of procedures performed in all countries remains high. However, the risk of potentially complex or fatal complications, though small, is present and is related to the procedures per se . This review is a guide for bariatric and/or general surgeons, offering a complete overview of the pathogenesis of anastomosis and staple line following the most common laparoscopic bariatric procedures: sleeve gastrectomy, gastric bypass, and mini-gastric bypass...

BACKGROUND: Laparoscopic single anastomosis (mini-)gastric bypass (LSAGB) has been validated as a safe and effective treatment for morbid obesity. However, data of the long-term outcome remain lacking. METHODS: Between October 2001 and December 2015, 1731 morbidly obese patients who received LSAGB as primary bariatric procedure at the Min-Sheng General Hospital were recruited. Surgical outcome, weight loss, resolution of comorbidities, and late complications were followed, then compared with groups of laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG)...

BACKGROUND: An increasing number of surgeons worldwide are now performing one anastomosis/mini gastric bypass (OAGB/MGB). Lack of a published consensus amongst experts may be hindering progress and affecting outcomes. This paper reports results from the first modified Delphi consensus building exercise on this procedure. METHODS: A committee of 16 recognised opinion-makers in bariatric surgery with special interest in OAGB/MGB was constituted. The committee invited 101 OAGB/MGB experts from 39 countries to vote on 55 statements in areas of controversy or variation associated with this procedure...

This paper reports a case of Petersen's space hernia after mini gastric bypass. This is an anecdotal post-operative complication in the mini gastric bypass technique, with an estimated rate of 1/5000 cases. Similar cases described in the literature were treated by the surgical hernia reduction and the closure of the mesenteric defect. Our patient had a unique management, performing a conversion to Roux-en-Y gastric bypass with dissection of the biliopancreatic limb at the anastomosis and creation of a variable foot-point anastomosis with excellent mid-term post-operative results...

BACKGROUND: Ten to 50% of patients who received restrictive bariatric operations may require reoperation for unsatisfactory weight loss or weight regain. Failed restrictive procedures are usually managed with conversion to another bariatric procedure with a favor of conversion to laparoscopic gastric bypass. Our aim is to evaluate two different bypass techniques, laparoscopic RY gastric bypass (RYGB) versus single-anastomosis (mini-) gastric bypass (SAGB) as a revision option (R-RYGB and R-SAGB) for failed restrictive bariatric operations...

PURPOSE OF REVIEW: Morbid obesity and type-2 diabetes mellitus (T2DM) are both major public health problems. Bariatric surgery is a proven and effective treatment for these conditions; laparoscopic Roux-en-Y gastric bypass (RYGB) is currently the gold-standard treatment. One-anastomosis gastric bypass (OAGB) is described as a simpler, safer, and non-inferior alternative to RYGB to treat morbid obesity. Concerning T2DM, experts of the OAGB procedure report promising metabolic results with good long-term remission of T2DM; however, heterogeneity within the literature prompted us to analyze this issue...

Many surgeons believe mini gastric bypass (MGB) is more likely to cause micronutrient malabsorption compared to Roux-en-Y gastric bypass (RYGB). Till date, there is no published study evaluating haematological indices and haematinic levels in patients undergoing MGB and comparing these with a matched cohort of RYGB. Two hundred patients who underwent MGB between October 2012 and October 2015 were matched to 200 patients who underwent RYGB for age, sex, body mass index and time of surgery. We then compared haemoglobin, mean corpuscular volume, iron, ferritin, vitamin B12 and folic acid levels preoperatively and at 6 monthly intervals after surgery until 2 years...
