The DeMeester score is used in the evaluation of which surgical condition?

• A Severity of portal hypertension in cirrhosis
• B Quantification of gastro-oesophageal reflux disease using 24-hour pH monitoring data ✓
• C Post-operative anastomotic leak grading after oesophagectomy
• D Severity of oesophageal dysmotility on high-resolution manometry

Explanation

The DeMeester score is a composite score derived from 24-hour ambulatory oesophageal pH monitoring that quantifies the severity of gastro-oesophageal reflux disease. It incorporates six components: total pH <4 time (%), upright pH <4 time (%), supine pH <4 time (%), total number of reflux episodes, number of episodes >5 minutes, and the longest reflux episode. A DeMeester score >14.72 is considered pathological (>95th percentile of normal). It is used to objectively confirm GERD before anti-reflux surgery (Nissen fundoplication) and to document recurrent reflux post-operatively.
