BACKGROUND Laparoscopic Roux-en-Y gastric bypass (LRYGB) can dramatically ameliorate type 2 diabetes mellitus (T2DM) in morbidly obese patients. However, there is little evidence supporting the effectiveness of LRYGB in low body mass index (BMI) patients. The study was designed to evaluate the safety and results of LRYGB for achieving T2DM remission in(More)
Obesity is a major public health concern around the world, including Asia. Bariatric surgery has grown in popularity to combat this rising trend. An e-mail questionnaire survey was sent to all the representative Asia-Pacific Metabolic and Bariatric Surgery Society (APMBSS) members of 12 leading Asian countries to provide bariatric surgery data for the last(More)
BACKGROUND Laparoscopic colectomy has yet to gain widespread acceptance in cost-conscious health-care institutions. The aim of the present study was to define the cost-benefit relationship of laparoscopic versus open colectomy. METHODS Thirty-two consecutive patients undergoing elective laparoscopic colectomy (LC) by a single colorectal surgeon between(More)
Laparoscopic appendectomy is being performed increasingly, worldwide. To the resident, it provides a valuable opportunity to master basic laparoscopic skills. Studies have shown that laparoscopic appendectomy performed by residents is safe. However, to date, there is no clear evidence for the minimum number of these operations required to achieving(More)
BACKGROUND Performing endoscopic submucosal dissection (ESD) by using standard endoscopy platforms is technically challenging because of the equipment's lack of dexterity. OBJECTIVE To explore the feasibility of using the Master and Slave Transluminal Endoscopic Robot (MASTER), a novel robotics-enhanced endosurgical system, to perform ESD. DESIGN ESD(More)
Adipose-derived stem/stromal cells (ASCs) from the anatomically distinct subcutaneous and visceral depots of white adipose tissue (WAT) differ in their inherent properties. However, little is known about the molecular identity and definitive markers of ASCs from these depots. In this study, ASCs from subcutaneous fat (SC-ASCs) and visceral fat (VS-ASCs) of(More)
Natural orifice transluminal endoscopic surgery (NOTES) has gained widespread interest as a potentially alternative to laparoscopic surgery, but concerns over peritoneal contaminations are unsolved. The aim of our study was to assess the safety of transluminal surgery by investigating the intraperitoneal bacterial load and contamination during transgastric(More)
The inferior surface of the liver’s left lobe overlies important structures such as the hepaticoduodenal ligament, the lesser omentum, and the gastroesophageal junction. Exposure of these structures is mandatory during dissection of lymphatic basin when total laparoscopic gastrectomy is performed. This report describes a liver retraction technique using a(More)
Tumors arising from the esophagogastric junction (OGJ) are increasing in incidence in the west, but data from Asian populations are conflicting. Singapore has a mixed-Asian population with an international lifestyle. This study was designed to examine the changing trends in incidence of gastric cardia cancer (type III) within this population and to compare(More)
