Abstract
Background: Gastroesophageal reflux disease - a condition where esophagus becomes irritated or inflamed due to acid reflux from the stomach. Another kind of acid reflux-causes respiratory and laryngeal signs and symptoms, is Laryngopharyngeal Reflux or "Extra Esophageal Reflux Disease". Laryngopharyngeal Reflux - backflow of stomach contents into throat that is into hypo pharynx.Primary defect in GERD -lower esophageal sphincter dysfunction whereas primary defect in LPR is upper esophageal sphincter dysfunction. Unlike GERD, LPR is unlikely to produce heartburn, and is called silent reflux. Injury to the human larynx does not require large volumes or continuous reflux of acidic gastric contents If antecedent injury- to vocal cord owing to viral infection, smoking, alcohol or voice abuse only intermittent exposure causes LPR symptoms. The pharynx and larynx are devoid of the acid clearance mechanism as found in the esophagus and are more liable to injury. LPR is usually easily diagnosed using Reflux Symptom Index and Reflux Finding Score. Here we undertake this study to find incidence of LPR in diagnosed cases of GERD, demographic profile of LPR patients and risk factors of LPR. Objectives of the study: To study incidence of LPR in diagnosed cases of GERD To study association of various risk factors in patients with LPR To study demographic profile in LPR patients Materials and Methods: All endoscopically diagnosed adult patients with GERD will be taken between july 2019 to Nov 2021. All patients will be contacted through telephonic communication,patients who give consent will be asked questions regarding the risk factors like alcohol intake, smoking, BMI, irregular food habits,history of consuming spicy foods,early sleep after food intake and RSI Endoscopic images will be assessed for RFS and hiatus hernia RSI- >13 and RFS- >7 -considered as LPR Results: In this study 62 patients were taken. Majority of study patients were in the age group of 29-39 years (39.1%). There was female preponderance in our study. LPR was present in 37 patients. Most of the patients were in normal BMI range. 64.8% had irregular intervals between meals. In our study 86.5% had a habit of early sleeping after intake of food. Most common comorbidity found in LPR patients was hypertension (27.4%) Conclusion: Incidence of LPR in GERD patients found to be 59.67% LPR was found to be predominant in females Most of the patients had irregular food intake, spicy food intake,early sleeping after food as risk factors for LPR. Even though 24 hour pH monitoring is the gold standard investigation for diagnosis of LPR, Reflux Symptom Index & Reflux Finding Score are easy tools in identifying patients with LPR as it is non-invasive and easy to perform.
