A Clinical Study to Evaluate the Efficacy and Safety of Hyoscine Butylbromide Capsules for Preoperative Preparation in Painless Gastrointestinal Endoscopy Procedures

Sponsor: Shanghai Jiao Tong University School of Medicine

Summary

Gastrointestinal endoscopy procedures, including upper gastrointestinal endoscopy and colorectal endoscopy, represent a fundamental and important method for examining and managing digestive tract diseases, with both diagnostic and therapeutic applications. They are also utilized as effective tools for surveillance of gastrointestinal tumors. During upper gastrointestinal endoscopy procedures, gastric peristalsis may restrict the operative field of view and access, significantly affecting procedural precision. Excessive peristalsis not only affects the observation of simple lesions but also impacts other procedural maneuvers Therefore, during upper gastrointestinal endoscopy procedures, antispasmodic agents are commonly used to suppress gastrointestinal motility, ultimately facilitating endoscopic visualization. However, most antispasmodic agents, such as hyoscine butylbromide (Buscopan), cimetropium bromide (Algiron), and atropine, must be administered by injection. Intravenous or intramuscular administration causes patient pain and anxiety, and increases medical costs. Some researchers have taken an alternative approach by spraying L-menthol onto the gastric mucosa during gastroscopy to reduce gastric peristalsis. Although study results and adverse reaction profiles have demonstrated its superiority, the application process still presents operational inconveniences. Furthermore, these drugs should be used with caution as they may cause potential adverse reactions, including dry mouth, urinary retention, temporary impairment of visual accommodation, palpitations, anaphylactic shock, and hyperglycemia.
