Brief Summary
The study will examine potential biological and genetic mechanisms leading to hiatal and paraesophageal hernia formation in predisposed individuals. It is expected that these patients will have defects in the normal production and maturation of collagen and other connective tissue proteins, thus leading to weakness in the diaphragm that may allow for spontaneous herniation. Comparison of tissue and blood samples from these patients (study group) will be made to those from individuals undergoing lower esophageal surgery who have not developed a concurrent hernia (i.e. esophageal myotomy for achalasia and laparoscopic gastric bypass or laparoscopic adjustable gastric banding for morbid obesity - control group).

Hiatal/Paraesophageal hernia patients
patients with hiatal or paraesophageal hernias
control group
patients without hiatal or paraesophageal hernias who are undergoing crural dissection for heller myotomy, or who are undergoing gastric bypass surgery
Eligibility Criteria
Patients to be enrolled in the study will be standard referrals to our group from primary care physicians or other specialists who feel that surgical correction of a diaphragmatic hernia or achalasia is necessary. Additionally, patients referred to our practice for weight reduction surgery will also be considered eligible for enrollment.
You may qualify if:
- Any patient undergoing paraesophageal hernia repair, esophageal myotomy, laparoscopic gastric bypass, or laparoscopic adjustable gastric banding.
You may not qualify if:
- Pregnant females, minors, prisoners
