To treat pancreatic exocrine insufficiency, physicians often prescribe enterically coated pellets of pancreatin to be taken with meals. The pellets are only partially effective in correcting the digestion and absorption of fat. We sought to determine in normal subjects whether emptying of pellets from the postcibal stomach was dose-related and whether the gastric emptying of lipophilic Creon-20 or Pancrease was altered by the presence or the absence of oil in a meal. Gastric emptying of pellets surface-labeled with 113mIn or 99mTc was followed with a gamma camera for 300 min after isocaloric meals. From our observations, we concluded that gastric emptying of 0.28-1.12 g of 1-mm or 2-mm pellets was dose-related (P < 0.01) and emptying of neither Creon-20 nor Pancrease was much affected by oil in the meal.

Introduction: Gastrointestinal (GI) magnetic resonance imaging (MRI) enables simultaneous assessment of gastric peristalsis, emptying, and intestinal filling and transit. However, GI MRI in animals typically requires anesthesia, which complicates physiology and confounds interpretation and translation to humans. This study aimed to establish GI MRI in conscious rats, and for the first time, characterize GI motor functions in awake versus anesthetized conditions.

Objectives: Cyclic vomiting syndrome (CVS) remains a diagnostic challenge due to its nonspecific presentation despite consensus-based diagnostic criteria. There is a need for improved, evidence-based diagnostic criteria. We hypothesized that symptoms differ quantitatively between children with CVS versus other vomiting conditions and that current diagnostic criteria are not sufficiently sensitive for diagnosing CVS.

Older adults are encouraged to increase their protein intake and engage in more physical activity to preserve muscle mass. However, since protein is considered the most satiating macronutrient, this advice might lead to a decrease in overall energy consumption. Physical activity is also recommended to older adults to enhance appetite, as it has been shown to help regulate appetite in younger adults, yet there is limited evidence to support this in older populations.

Semaglutide, a glucagon-like peptide-1 receptor agonist, used for Type 2 diabetes mellitus and more recently for weight loss, often causes gastrointestinal adverse effects such as delayed gastric emptying and abdominal discomfort. Current literature has not described an associated case of gastric pneumatosis with semaglutide use. We report a 61-year-old man on semaglutide for 9 months with gastric pneumatosis.

Introduction: Gastroparesis is a debilitating gastroduodenal disorder for which gastric peroral endoscopic myotomy (GPOEM) has emerged as an efficacious treatment option. However, response to GPOEM varies between 50% and 80%, such that preoperative predictors of treatment success are needed to guide patient selection.
Methods: We performed a systematic review to identify predictors of clinical and functional response to GPOEM among adult patients with gastroparesis (PROSPERO: CRD42023457359).
