Background:
We evaluated the relationship between comorbidities associated with obesity, body mass index (BMI), and development of intestinal metaplasia (IM) after vertical sleeve gastrectomy (VSG).
Materials And Methods:
All VSG specimens performed at an academic center between 2011 and 2018 were reviewed. All specimens underwent histopathologic assessment, while those with findings suspicious for IM underwent additional immunohistochemical work up. Baseline patient characteristics and demographic data were obtained from Iran National Obesity Surgery Database by retrospective review.
Results:
A total of 862 adult individuals underwent VSG during the study period and specimens were histopathologically examined. All patients had preoperative upper endoscopy. The most common histopathologic diagnosis was miscellaneous findings (57.8%) followed by no pathologic finding (36.7%). The minority of patients (5.5%) had IM. Although 40.5% of patients had positive Helicobacter pylori infection preoperatively, just 13.8% had still positive infection postoperatively. A significant association was found between IM and hypercholesterolemia (odds ratio: 1.95; 95% confidence interval: 1.1, 3.5).
Conclusion:
This study found a correlation between histopathologic changes in patients with IM and hypercholesterolemia. Prospective research studies are recommended to further examine this correlation.

01:17Gastritis-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...

01:23Gastritis III: Clinical Manifestations and Management
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
01:28Peptic Ulcer Disease II: Pathophysiology
Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.
