Author Spotlight: Point-of-Care Ultrasound for Gastric Content Assessment and Risk Stratification in Perioperative Care

Abstract:
Gastric ulcers have been thought to occur only in the pyloric gland area. However, endoscopic examinations using the Congo red test showed that 18 of the ulcers examined (7.8%) were surrounded by an acid-secreting area, and so were in the fundic gland area. Histological examination of specimens obtained by gastrectomy also showed that five of the lesions examined (4.5%) were located in the fundic gland area. Ulcers in the fundic gland area were found most frequently in the angle and lower gastric body, adjacent to acid-secreting boundary. These ulcers were associated with little or no fundal gastritis, whereas ulcers in the pyloric gland area were usually associated with moderate or severe fundal gastritis. Unlike ulcers of similar depth in the pyloric gland area, ulcers surrounded by normal fundic mucosa healed rapidly and completely. No recurrence of these ulcers was seen in a 1-year endoscopic follow-up period.

Pathophysiology of Peptic Ulcer Disease: Injurious Factors
In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds...

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
