Introduction: Hiatal hernia is a condition where a part of the stomach protrudes through an opening in the diaphragm into the chest cavity, which can cause gastroesophageal reflux disease (GERD), and other symptoms such as heartburn, regurgitation, abdominal and chest pain, and chronic cough. Due to symptom overlap with other digestive issues, diagnosis can be challenging. Advances in research have revealed significant pathophysiological mechanisms linking hiatal hernia and GERD. Early studies focused on local pathophysiology, whereas current research emphasizes the interconnection of symptoms and diagnostic aspects to improve disease management and understanding. Objective: The main aim of this study is to analyze the laparoscopic treatment of hiatal hernia and GERD, with a particular focus on the case presentation of patients treated using this method at the General Hospital Zadar. Participants and Methods: The study will utilize data from all patients diagnosed with hiatal hernia who underwent laparoscopic surgery between 2015 and 2023. The analysis will be based on the hospital information system (BIS) of the General Hospital Zadar to present patient cases. After collecting relevant data using case presentation forms, data will be analyzed using descriptive statistical methods and Microsoft Excel. Results: The database search identified a total of 49 patients who underwent laparoscopic surgery between 2015 and 2023. Five patients were excluded from further analysis due to insufficient data, resulting in a final analysis of 44 patients. Conclusion: This study emphasizes the importance of recognizing and treating hiatal hernia and gastroesophageal reflux disease (GERD) promptly, particularly considering their impact on patients' quality of life. Laparoscopic treatment has proven to be an effective option with a low complication rate, offering patients quicker recovery and better postoperative outcomes. Based on the study's overall results conducted at the General Hospital Zadar, laparoscopic surgery can be considered the gold standard in treating hiatal hernia, potentially reducing GERD symptoms.
