Show Answer & Explanation

Correct Answer

c) Combination of sliding and paraesophageal hernia

Explanation

Hiatal hernias are classified based on the position of the gastroesophageal junction and stomach. Type I involves upward displacement of the GEJ into the thorax. Type II has a normally positioned GEJ with part of the stomach herniating alongside the esophagus. Type III is a mixed hernia where both the GEJ and stomach herniate into the thoracic cavity. Option (d) is more consistent with a giant paraesophageal hernia (Type IV).

Teaching Points

Type I is the most common and associated with GERD
Type III is a mixed hernia involving GEJ and stomach
Type II and III have higher risk of volvulus and strangulation
Large hernias with most of the stomach in chest are Type IV
