Background: Gastroesophageal disease (GERD) is a highly prevalent gastrointestinal disease. In rural areas, general surgeons perform esophagogastroduodenoscopy (EGD) despite its low diagnostic yield. When EGD findings are equivocal, GERD patients are usually referred to tertiary hospitals for further workup. We envisaged establishing a comprehensive anti-reflux program with diagnostic and therapeutic capabilities in a rural setting.
Study design: This is an IRB approved retrospective chart review of patients who presented with GERD symptoms to a rural anti-reflux clinic between August 2015 and February 2021. Standardized workup included upper gastrointestinal study and EGD with concomitant wireless pH placement. High resolution impedance manometry and gastric emptying scans were selectively utilized initially, then were performed routinely. We used endoFLIP impedance planimetry system starting in February 2019.
Results: A total of 830 patients were evaluated. There were 537 (64.6%) females and 293 (35.4%) males. The average age was 57.7 ± 15.2 years. The average BMI was 30.8 ± 6.7 kg/m2. Approximately one-third of these patients were referred by the primary care provider (PCP) within our health system and a comparable percentage from external PCPs. Self referral was noted in 15.4% and 19.2% were referred by different specialties such as pulmonary (10.7%), surgical for large hiatal hernia (5.8%), inpatient and emergency room (2%), and gastroenterology (0.7%).
Conclusion: Rural surgeons with appropriate endoscopic and laparoscopic training can establish a comprehensive anti-reflux program with diagnostic and therapeutic capabilities. It meets the high community need and can expand to be a regional center. The revenues generated are critical for the financial survival of rural hospitals.
