Findings with swan-type double-bending gastrofiberscope.

Area of Science:

• Gastroenterology
• Endoscopy
• Medical Imaging

Background:

• Traditional endoscopic methods have limitations in visualizing specific gastric regions.
• Accurate assessment of gastric anatomy and pathology is crucial for diagnosis and treatment.

Purpose of the Study:

• To evaluate the utility of a swan-type double-bending gastrofiberscope for detailed observation of the cardia, posterior wall of the upper corpus, and pyloric region.
• To correlate endoscopic findings with gastric conditions such as cardia dysfunction, pathological elevations, and gastric ulcers.

Main Methods:

• Utilized a swan-type double-bending gastrofiberscope for endoscopic examinations.
• Observed and classified features of the cardia, esophagogastric junction, posterior wall of the upper corpus, and pyloric region.
• Analyzed fold patterns, elevations, and signs of ulcer healing and recurrence.

Main Results:

• Clear visualization of the cardia and esophagogastric junction, enabling diagnosis of cardia dysfunction based on fold morphology and air inflation.
• Classification of posterior wall upper corpus elevations into three types (flat, slightly elevated, highly elevated) for pathological assessment.
• Detailed observation of pyloric region folds (radiated, transverse, lost) correlated with erosions and endoscopic signs of gastric ulcer healing (radiating vessels, scar contraction) and recurrence.

Conclusions:

• The swan-type gastrofiberscope significantly improves visualization of key gastric areas, facilitating diagnosis of cardia dysfunction.
• Endoscopic assessment of posterior wall elevations and pyloric region fold changes provides insights into pathological conditions and ulcer progression.
• The study highlights the value of specific endoscopic findings in monitoring gastric ulcer healing and recurrence.
