Introduction
Chronic anemia is a common, coinciding or presenting diagnosis in patients with paraesophageal hernia (PEH). Presence of endoscopically identified ulcerations frequently prompts surgical consultation in the otherwise asymptomatic patient with anemia. Rates of anemia resolution following paraesophageal hernia repair (PEHR) often exceed the prevalence of such lesions in the study population. A defined algorithm remains elusive. This study aims to characterize resolution of anemia after PEHR with respect to endoscopic diagnosis.
Materials and methods
Retrospective review of a prospectively maintained database of patients with PEH and anemia undergoing PEHR from 2007 to 2018 was performed. Anemia was determined by preoperative labs: Hgb < 12 mg/dl in females, Hgb < 13 mg/dl in males, or patients with ongoing iron supplementation. Improvement of post-operative anemia was assessed by post-operative hemoglobin values and continued necessity of iron supplementation.
Results
Among 56 identified patients, 45 were female (80.4%). Forty patients (71.4%) were anemic by hemoglobin value, 16 patients (28.6%) required iron supplementation. Mean age was 65.1 years, with mean BMI of 27.7 kg/m2. One case was a Type IV PEH and the rest Type III. 32 (64.0%) had potential source of anemia: 16 (32.0%) Cameron lesions, 6 (12.0%) gastric ulcers, 12 (24.0%) gastritis. 10 (20.0%) had esophagitis and 4 (8%) Barrett’s esophagus. 18 (36%) PEH patients had normal preoperative EGD. Median follow-up was 160 days. Anemia resolution occurred in 46.4% of patients. Of the 16 patients with pre-procedure Cameron lesions, 10 (63%) had resolution of anemia. Patients with esophagitis did not achieve resolution. 72.2% (13/18) of patients with no lesions on EGD had anemia resolution (p = 0.03).
Conclusion
Patients with PEH and identifiable ulcerations showed 50% resolution of anemia after hernia repair. Patients without identifiable lesions on endoscopy demonstrated statistically significant resolution of anemia in 72.2% of cases. Anemia associated with PEH adds an indication for surgical repair with curative intent.
