Study on weight loss outcomes after bariatric surgery to determine a metric least influenced by preoperative BMI.

Background: Percentage excess weight loss (%EWL) and percentage total weight loss (%TWL) are used for reporting outcomes after bariatric surgery. However, they are not ideal for comparing outcomes on populations of varied initial body mass index (BMI). This study aimed to validate a recently introduced metric - percentage alterable weight loss (%AWL), after laparoscopic sleeve gastrectomy (LSG) and Roux-en-Y gastric bypass (LRYGB).

Endovascular retrograde recanalization in Asian critical limb ischaemia patients.

Background: To evaluate endovascular retrograde recanalization of critical limb ischaemia (CLI) patients with chronic total occlusions (CTOs) in an Asian population.

Methods: We conducted a single centre-based retrospective review of CLI patients with CTOs who had undergone endovascular retrograde recanalization using the subintimal arterial flossing with antegrade-retrograde intervention technique.

Results: A total of 40 CLI patients with CTOs underwent endovascular intervention.

Early outcomes of laparoscopic sleeve gastrectomy in a multiethnic Asian cohort.

Background: Laparoscopic sleeve gastrectomy (LSG) has become a popular bariatric operation worldwide.

Objectives: To report early outcomes of patients with LSG performed.

Settings: University hospital and a restructured hospital, Singapore.

The use of a second biopsy from the gastric body for the detection of Helicobacter pylori using rapid urease test.

Introduction: The use of an additional biopsy from the gastric body may help improve the detection of Helicobacter pylori during endoscopy. This study aimed to determine whether such an additional biopsy is necessary in routine rapid urease test (RUT), and whether acid suppression and antibiotic therapy affect RUT results.

Methods: Patients recruited had two gastric mucosal biopsies taken - one from the gastric antrum and the other from the gastric body.

Spectral analysis of bowel sounds in intestinal obstruction using an electronic stethoscope.

Aim: To determine the value of bowel sounds analysis using an electronic stethoscope to support a clinical diagnosis of intestinal obstruction.

Methods: Subjects were patients who presented with a diagnosis of possible intestinal obstruction based on symptoms, signs, and radiological findings. A 3M™ Littmann(®) Model 4100 electronic stethoscope was used in this study.

Comparison of torsional and linear mode ultrasonic coagulating shears for sealing veins.

Background: Torsional mode ultrasonic coagulating shears are an alternative device to linear mode shears for hemostatic cutting. The aim of this study was to compare the vessel-sealing quality of torsional and linear mode ultrasonic coagulating shears on human veins.

Materials And Methods: Veins were harvested from 15 patients during varicose vein surgery.

Treatment of Helicobacter pylori in surgical practice: a randomised trial of triple versus quadruple therapy in a rural district general hospital.

Aim: To compare a lansoprazole-based triple versus quadruple therapy for Helicobacter pylori (H pylori) eradication with emphasis on side effect profile, patient compliance and eradication rate at a rural district general hospital in Wales, United Kingdom.

Methods: One hundred one patients with H pylori infection were included in the study. Patients were randomised to receive triple therapy comprising of lansoprazole 30 mg, amoxycillin 1 g, clarithromycin 500 mg, all b.
