Introduction:
Helicobacter pylori is a gram-negative gut bacterium associated with dyspepsia, peptic ulcer disease, and gastric cancer, whose prevalence is still common in developing countries. Upper gastrointestinal endoscopy is the gold standard, first-line investigation for evaluating gastrointestinal disorders. The aim of the study was to find out the prevalence of Helicobacter pylori infection among patients undergoing upper gastrointestinal endoscopy in a tertiary care centre.
Methods:
A descriptive cross-sectional study was conducted in a tertiary health care centre among the patients undergoing upper gastrointestinal endoscopy from 5 January 2020 to 5 January 2023 after obtaining ethical approval from the Institutional Review Committee. Convenience sampling method was used. The point estimate was calculated at a 99% Confidence Interval.
Results:
Among 1,975 patients, Helicobacter pylori infection was found in 561 (28.41%) (25.79-31.03, 99% Confidence Interval). The indication for upper gastrointestinal endoscopy was mostly dyspepsia 256 (45.68%) followed by abdominal pain 205 (36.54%). The most common endoscopic finding was gastritis 445 (79.32%) followed by hiatal hernia 93 (16.58%). The commonest biopsy finding was chronic active gastritis 478 (85.20%).
Conclusions:
The prevalence of Helicobacter pylori infection among patients undergoing upper gastrointestinal endoscopy was found to be similar to other studies done in similar settings. The persistence of H. pylori emphasizes the need of continuous research to address ever evolving H. pylori infections and resistance that are developing against available treatment modalities.
Keywords:

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.

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...
