Foregut (foregut exclusions) and hindgut (rapid transit of nutrients to the distal intestine) theories are the most commonly used explanations for the metabolic improvements observed after metabolic surgeries. However, several procedures that do not comprise duodenal exclusions, such as sleeve with jejunojejunal bypass, ileal interposition, and transit bipartition and sleeve gastrectomy were found to have similar diabetes remission rates when compared with duodenal exclusion procedures, such as gastric bypass, biliopancreatic diversion with duodenal switch, and diverted sleeve with ileal interposition. Moreover, the complete exclusion of the proximal intestine could result in the malabsorption of several important micronutrients. This article reviews commonly performed procedures, with and without foregut exclusion, to better comprehend whether there is a critical need to include foregut exclusion in metabolic surgery.

Median Arcuate Ligament Syndrome: Where Are We Today?

Median arcuate ligament syndrome, or celiac artery compression syndrome (eponym: Dunbar syndrome), has historically been attributed to pathophysiologic vascular compression causing downstream ischemic symptoms of the organs supplied by the celiac trunk. However, the more we learn about the histology, clinical presentation, and treatment outcomes, health care providers are increasingly correlating the symptoms of MALS with the long-term, repetitive compression of the celiac ganglion rather than the celiac trunk. This article provides a comprehensive review of current MALS literature, emphasizing the multidisciplinary approach these patients require in all phases of their care.

Glucagon-like peptide receptor agonists (GLP-1 RAs) are associated with delayed gastric emptying and may increase the risk of aspiration due to retained gastric contents. There are no guidelines on peri-endoscopic use of GLP-1 RAs, and real-world outcomes in an ambulatory setting remain unknown. This study reports real-world data from an ambulatory center associated with a large tertiary hospital.

Article Synopsis
- The study investigates the presence of achalasia in patients identified with absent contractility on high-resolution manometry (HRM), distinguishing it from other conditions by employing additional tests like barium esophagography and FLIP.
- Out of 164 patients, 20 (12.2%) were diagnosed with achalasia, with notable clinical differences between them and those without obstruction, particularly in symptoms like dysphagia and specific HRM features.
- The findings suggest that even when absent contractility is detected, there remains a significant chance of underlying achalasia, emphasizing the need for thorough diagnostic evaluation beyond just HRM results.
Introduction: Obesity is an increasingly prevalent public health problem often associated with poorly controlled gastroesophageal reflux disease. Fundoplication has been shown to have limited long-term efficacy in patients with morbid obesity and does not address additional weight-related co-morbidities. Roux-en-Y gastric bypass (RYGB) is the gold standard operation for durable resolution of GERD in patients with obesity, and is also used as a salvage operation for GERD after prior foregut surgery.
