Abstract

Intravenous propofol can provide a superior quality of sedation compared to standard sedation for upper gastrointestinal endoscopy. However, the utility of propofol sedation for the endoscopic early detection of superficial pharyngeal and esophageal squamous cell carcinoma has not been investigated. In a multicenter, prospective trial, 255 patients with esophageal squamous cell carcinomas (ESCCs) were assigned to receive propofol sedation or no sedation according to their own willingness. The primary aim was to compare the detection rates of superficial cancer in the pharyngeal region and the esophagus between two groups. The secondary aim was to evaluate factors associated with technical adequacy. The detection rate was higher in the propofol sedation vs. no sedation group for H&N region (6.06% vs. 2.40%), but not significantly (P=0.22). However, the small lesion (less than 10 mm in diameter) detection rate was higher in sedation vs. no sedation group for H&N region (88.89% vs. 33.33%; P=0.048). The median time for pharyngeal observation in the sedation group was faster than in the no sedation group (20.6 s vs. 44.3 s; P<0.001). Ninety-five percent of H&N region evaluations were totally complete in sedation compared with sixty...Continue Reading
