Modern diagnosis and treatment of hiatal hernias.

PURPOSE: Hiatal hernias are a common finding on radiographic or endoscopic studies. Hiatal hernias may become symptomatic or, less frequently, can incarcerate or become a volvulus leading to organ ischemia. This review examines latest evidence on the diagnostic workup and management of hiatal hernias.

METHODS: A literature review of contemporary and latest studies with highest quality of evidence was completed. This information was examined and compiled in review format.

RESULTS: Asymptomatic hiatal and paraesophageal hernias become symptomatic and necessitate repair at a rate of 1% per year. Watchful waiting is appropriate for asymptomatic hernias. Symptomatic hiatal hernias and those with confirmed reflux disease require operative repair with an anti-reflux procedure. Key operative steps include the following: reduction and excision of hernia sac, 3 cm of intraabdominal esophageal length, crural closure with mesh reinforcement, and an anti-reflux procedure. Repairs not amenable to key steps may undergo gastropexy and gastrostomy placement as an alternative procedure.

CONCLUSIONS: Hiatal hernias are commonly incidental findings. When hernias become symptomatic or have reflux disease, an operative repair is required. A minimally invasive approach is safe and has improved outcomes.
