INTRODUCTIONOutcomes 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.

MATERIALS AND METHODSA 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.

RESULTSThere 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.

CONCLUSIONLSG 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.

Helicobacter pylori (H. pylori) is an infection that has a role in causing dyspepsia and complications such as peptic ulcer disease and gastric malignancies. In the primary care setting, one can adopt a stepwise approach with the 'test-and-treat' strategy to manage H. pylori-associated dyspepsia in young patients without alarm symptoms. Empiric first-line therapies should be for a two-week duration; options include clarithromycin-containing triple therapy alone or with the addition of bismuth, concomitant therapy and bismuth quadruple therapy. Post-treatment carbon urea breath test must be performed at least four weeks after the end of treatment to confirm the cure. Options for empiric second-line treatment include bismuth quadruple therapy and levofloxacin-containing triple therapy. Patients with persistent or alarm symptoms should be referred for further evaluation. Patients with persistent infection should be referred for gastroscopy so that gastric biopsies can be obtained for H. pylori culture and antibiotic susceptibility testing.
