Laparoscopic sleeve gastrectomy for morbidly obese adolescents in Singapore

INTRODUCTION@#Laparoscopic sleeve gastrectomy (LSG) outcomes among adolescents and factors associated with adolescent obesity in Singapore were evaluated.@*METHODS@#Prospectively collected data of patients aged 16-19 years who underwent LSG was retrospectively reviewed. A lifestyle questionnaire, Berlin and Epworth scores, and Patient Health Questionnaire-9 scores were collected. Preoperative anthropometrics, comorbidities, weight loss and body composition outcomes were recorded.@*RESULTS@#Among 208 LSGs, 13 (6.3%) were performed on obese adolescents. Mean age and body mass index (BMI) at first presentation were 19.1 ± 0.9 (range 16.8-19.8) years and 46.2 ± 6.3 (range 36-57) kg/m, respectively. There was family history of obesity (n = 7) and regular consumption of high-calorie drinks (n = 12). Most patients had comorbidities (n = 12), including hypertension (n = 5), asthma (n = 4), diabetes mellitus (n = 3), hernia (n = 3) and obstructive sleep apnoea requiring continuous positive airway pressure support (n = 3). At one year, excess weight loss was 64.3% ± 34.7% (range 21.8%-101.5%), while BMI and fat mass dropped to 31.2 ± 7.6 (range 23-40) kg/m and 17.4 kg, respectively. Pain score was 2/10 at 24 hours after surgery. Mean postoperative stay was 2.7 days. No complications or readmissions occurred. Remission of diabetes mellitus and hypertension was reported in two of three and four of five adolescents, respectively, within one year of surgery.@*CONCLUSION@#LSG is a safe option for adolescents with good short-term weight loss outcomes and remission of metabolic comorbid conditions.

Is Laparoscopic Sleeve Gastrectomy for Asian Super Obese a Safe and Effective Procedure?

<p><b>INTRODUCTION</b>Outcomes of bariatric surgery for super obese Asians are not well reported. We aimed to compare short-term outcomes of laparoscopic sleeve gastrectomy (LSG) in Asian patients with body mass index (BMI) <47.5 kg/m to those with BMI •••••• ≥47.5 kg/m.</p><p><b>MATERIALS AND METHODS</b>A total of 272 patients from Singapore university hospital who underwent LSG from 2008 to 2015 with a follow-up of at least 6 months were included in the study. Primary endpoint was weight loss at 1-year and 3-years. Morbid obesity (Group 1, G1) was defined as BMI <47.5 kg/m and super obesity (Group2, G2) was defined as BMI ≥47.5 kg/m.</p><p><b>RESULTS</b>There were 215 patients in G1 and 57 patients in G2 (mean preoperative weight: 107.3 kg and 146.8 kg; mean follow-up: 27.9 and 26.8 months, respectively). Mean total weight loss at 3-year of 41.9 kg for G2 was significantly higher ( = 0.003) than 27.2 kg for G1. Mean percentage excess weight loss (EWL) did not differ at 3-years. There was no difference in operating time, blood loss, length of stay, 30-day morbidity and readmission. There were no conversions and mortality in both groups. Remission of herpertension ( - 0.001) and dyslipidaemia ( = 0.038) were significantly associated with achieving EWL percentage (%EWL) >50 in G1.</p><p><b>CONCLUSION</b>LSG is an equally safe and effective operation in Asians with BMI ≥47.5 kg/m2 when compare to patients with BMI <47.5 kg/m in achieving significant weight loss and improvement in comorbidities. Super obese lose more weight but have lower %EWL.</p>

Attitudes and Concerns of Diabetic Patients towards Bariatric Surgery as Treatment of Diabetes

<p><b>INTRODUCTION</b>Bariatric surgery is increasingly recognised as an effective treatment for type 2 diabetes that significantly improves glycaemic control, even achieving remission. This study examined perceptions and concerns of diabetic patients towards bariatric surgery as a treatment option for diabetes.</p><p><b>MATERIALS AND METHODS</b>A total of 150 patients were recruited from a specialised diabetic outpatient clinic and completed a questionnaire (items were rated on a Likert scale from slightly important [lowest score of 1] to extremely important [maximum score of 5]). Logistic regression was performed to identify factors influencing decision for surgery.</p><p><b>RESULTS</b>The 74 males and 76 females had mean age of 50 (range 20 to 78) and body mass index (BMI) of 29.6 kg/m(range 18.1 to 51); 61% considered surgery favourably. Predictive factors for interest in surgery: higher educational levels (OR = 2.3; 95% CI, 1.2 to 4.4), duration of diabetes (OR = 0.4; 95% CI, 0.2 to 1.0) and use of insulin (OR = 2.1; 95% CI, 1.1 to 4.1). Reasons for surgery: desire for remission (Likert scale 4.7 ± 0.7), to prevent complications (Likert scale 4.5 ± 0.9) and to reduce medications (Likert scale 4.3 ± 1.1). For those not keen on surgery, main reasons were fear of surgery (Likert scale 4 ± 1.5) and satisfaction with current therapy (Likert scale 3.7 ± 1.6).</p><p><b>CONCLUSION</b>Many diabetic patients would consider surgery as an option to improve their metabolic disorder (greater interest in patients with higher educational levels, currently using insulin and with shorter duration of diabetes). Surgical complications, length of recovery and duration of benefits were the main concerns.</p>
