Background: Obesity and lymphedema pose serious public healthcare problems. Though there are clear links between both chronic conditions, they are rarely treated together.

Methods: We describe the successful management of secondary lower limb lymphedema by the combination of obesity and lymphedema treatment in a 44-year-old patient with a body mass index of 35.

Introduction: For ventral/incisional hernias between 1 and 4 cm, there is still controversy regarding open or laparoscopic mesh repairs. The study evaluated via a propensity-score adjusted analysis, the differences in outcomes between a laparoscopic and open ventral hernia mesh repair.

Methodology: A single institution retrospective cohort study was performed.

Introduction: Malignant gastric outlet obstruction (GOO) has a significant impact on quality of life. Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) has shown promising results. Traditional isolated outcome measures do not sufficiently address critical considerations for end-of-life patients like oral intake tolerance.

Background: Multimodal prehabilitation programs, which may incorporate nutritional supplementation and exercise, have been developed to combat sarcopenia in surgical patients to enhance post-operative outcomes. However, the optimal regime remains unknown. The use of beta-hydroxy beta-methylbutyrate (HMB) has beneficial effects on muscle mass and strength.

Article Synopsis
  • Esophagogastric junction outflow obstruction (EGJOO) is an esophageal disorder with a high integrated relaxation pressure, and while symptoms are usually self-limiting, this study investigates factors that affect symptom resolution.
  • A cohort study of 53 patients revealed that while dysphagia and atypical chest pain were common symptoms, obesity was a significant risk factor for persistent symptoms, with only 37.5% of obese patients seeing resolution compared to 87.2% of non-obese patients.
  • The study emphasizes that addressing obesity may be crucial for improving outcomes in patients with functional EGJOO, as it significantly impacts the likelihood of symptom resolution.

Sarcopenia has been recognized as a determining factor in surgical outcomes and is associated with an increased risk of postoperative complications and readmission. Diagnosis is currently based on clinical guidelines, which includes assessment of skeletal muscle mass but not quality. Ultrasound has been proposed as a useful point-of-care diagnostic tool to assess muscle quality, but no validated cut-offs for sarcopenia have been reported.

Background: The slit-mesh technique for laparoscopic groin hernia repair remains controversial. We present the largest cohort of patients to date that have undergone laparoscopic hernia repair with this technique and aim to evaluate the impact of both techniques on postoperative recurrence and other secondary outcomes.

Methods: A retrospective, single-institution cohort study of patients who underwent a laparoscopic groin hernia repair over a 5.

Introduction: Laparoscopic sleeve gastrectomy (LSG) is associated with postoperative gastroesophageal reflux disease (GERD) and erosive esophagitis (EE). The role of crural repair during LSG is still controversial. The preoperative laxity of the gastroesophageal junction (GEJ), graded by the Hill's classification, is more predictive for postoperative GERD and EE after LSG than the presence of a hiatal hernia seen on endoscopy.

Background: Laparoscopic sleeve gastrectomy (SG) is a widely performed bariatric surgery, but it is associated with an increased risk of gastroesophageal reflux (GERD) in the long term. The addition of fundoplication to laparoscopic SG may improve lower oesophageal sphincter function and reduce postoperative GERD.

Objectives: This systematic review and meta-analysis aims to compare the efficacy and safety of SG plus fundoplication (SG + F) versus SG alone for the treatment of patients with severe obesity (≥35 kg/m).

Background: We aimed to investigate the association between time from admission to appendectomy on perioperative outcomes in order to determine optimal time-to-surgery windows.

Methods: We performed a retrospective review of all the appendectomies performed between July 2018 to May 2020. We first compared the perioperative outcomes using preselected time-to-surgery cut-offs, then determined optimal safe windows for surgery, and finally identified subgroups of patients who may require early intervention.

Background: Laparoscopic sleeve gastrectomy (LSG) is one of the commonest bariatric procedures. However, it is associated with postoperative gastroesophageal reflux disease (GERD) and erosive esophagitis (EE). This study aims to assess the impact of various preoperative clinical and endoscopic characteristics on the development of postoperative GERD and EE.

Article Synopsis
  • The prevalence of hiatal hernias and para-oesophageal hernias (PEHs) is notably lower in Asian populations compared to Western populations, yet giant PEHs can lead to serious health issues.
  • During a 10-year study at Changi General Hospital in Singapore, ten patients underwent surgical repair for giant PEH or parahiatal hernia, with a mix of emergency and elective procedures, showing positive outcomes and no complications.
  • The findings suggest that giant PEHs and parahiatal hernias are often underdiagnosed in Asia, and emphasize the importance of early detection and planned surgical intervention to improve patient outcomes.
