The Glutamate-Serine-Glycine Index as a Biomarker to Monitor the Effects of Bariatric Surgery on Non-alcoholic Fatty Liver Disease.

Objective: Bariatric surgery effectively treats non-alcoholic fatty liver disease (NAFLD). The glutamate-serine-glycine (GSG) index has emerged as a non-invasive diagnostic marker for NAFLD, but its ability to monitor treatment response remains unclear. This study investigates the GSG index's ability to monitor NAFLD's response to bariatric surgery.

Real-World Outcomes for Localised Gastro-Oesophageal Adenocarcinoma Cancer Treated with Perioperative FLOT and Prophylactic GCSF Support in a Single Asian Centre.

Background: Perioperative FLOT (5-fluorouracil, oxaliplatin and docetaxel) is a standard of care for patients with locally advanced gastro-oesophageal adenocarcinoma (GEA) in Western guidelines, but its use is limited in Asian patients. We report outcomes from a single Asian centre of perioperative FLOT with concomitant granulocyte colony-stimulating factor (GCSF) prophylaxis.

Methods: A retrospective analysis of all 56 stage II to III GEA patients treated with perioperative FLOT at the National Cancer Centre Singapore between June 2017 and February 2024 was performed.

Small hiatal hernia and postprandial reflux after vertical sleeve gastrectomy: A multiethnic Asian cohort.

Background: Laparoscopic vertical sleeve gastrectomy (LSG) is a popular bariatric procedure performed in Asia, as obesity continues to be on the rise in our population. A major problem faced is the development of de novo gastroesophageal reflux disease (GERD) after LSG, which can be chronic and debilitating. In this study, we aim to assess the relationship between the presence of small hiatal hernia (HH) and the development of postoperative GERD, as well as to explore the correlation between GERD symptoms after LSG and timing of meals.

Effectiveness of bariatric surgery in diabetes prevention in high-risk Asian individuals.

Introduction: Obesity is a key risk factor in the development of Type 2 diabetes mellitus (T2DM). Bariatric surgery causes a large amount of durable weight loss in those with clinically severe obesity. We reported the effect of weight loss via bariatric surgery on DM prevention in those at high risk of developing DM.

Five-year long-term clinical outcome after bariatric metabolic surgery: A multi-ethnic Asian population in Singapore.

Bariatric surgery is an effective treatment for morbid obesity and its metabolic related comorbidities; type 2 diabetes, hypertension and hyperlipidaemia. 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 surgeries in Asia, we have attempted to provide a regional perspective on 5-year long-term clinical outcomes post bariatric surgery in Singapore.

Laparoscopic wedge resection for suspected large (≥5 cm) gastric gastrointestinal stromal tumors.

Background: Laparoscopic wedge resection (LWR) for small gastric gastrointestinal stromal tumors (GIST) is now widely accepted, but its application for large GISTs remains controversial. This study aims to evaluate the feasibility and safety of LWR for suspected large (≥5 cm) gastric GISTs.

Methods: Retrospective review of 82 consecutive patients who underwent attempted LWR for suspected gastric GIST.

The Effects of Sleeve Gastrectomy and Gastric Bypass on Branched-Chain Amino Acid Metabolism 1 Year After Bariatric Surgery.

Background: Weight loss, early after Roux-en-Y gastric bypass (GB) surgery, is associated with reduced concentrations of plasma branched-chain amino acids (BCAAs) and improved insulin sensitivity. Herein, we evaluated whether changes in BCAAs and insulin sensitivity persist with weight stabilization (1 year) after GB or sleeve gastrectomy (SG).

Methods: We prospectively examined 22 severely obese patients (mean age 40.

Endoscopic self-expandable metallic stenting for palliation of malignant gastric outlet obstruction in Southeast Asia.

Background: Malignant gastric outlet obstruction (GOO) is a pre-terminal event in the natural history of gastric and pancreaticobiliary cancers. The use of endoscopic placement of self-expandable metallic stents (SEMS) is a less invasive alternative palliative option for these patients. This is the first study in Southeast Asia to evaluate the clinical efficacy and safety of endoscopic SEMS placement in patients with malignant GOO.

Single-port laparoscopic distal gastrectomy with D1+β lymph node dissection for gastric cancers: report of 2 cases.

The use of single-port laparoscopic surgery for treating various diseases has increased rapidly. This approach can offer better cosmetic results and less incisional pain. We report the cases of single-port laparoscopic distal gastrectomy with D1+β lymph node dissection for 2 patients with gastric cancers.
