Coffee enema for preparation for small bowel video capsule endoscopy: a pilot study

Area of Science:

• Gastroenterology
• Medical Procedures
• Diagnostic Imaging

Background:

• Coffee enemas are an alternative therapy believed to stimulate bile excretion.
• Excreted bile can compromise small bowel preparation for video capsule endoscopy (VCE).
• The role of coffee enemas in VCE preparation is not well-established.

Purpose of the Study:

• To evaluate the feasibility and effectiveness of coffee enemas for small bowel preparation during VCE.
• To compare bowel preparation quality between patients receiving coffee enema plus polyethylene glycol (PEG) and PEG alone.

Main Methods:

• A pilot study involving 34 patients undergoing VCE.
• 17 patients received coffee enema plus 2 L PEG; 17 control patients received 2 L PEG only.
• Bowel preparation quality was assessed in proximal, mid, and distal small bowel segments.

Main Results:

• No significant difference in proximal small bowel preparation between groups.
• A trend towards better mid and distal small bowel preparation in the coffee enema plus PEG group.
• No complications or adverse events were reported in the coffee enema group.

Conclusions:

• Coffee enemas appear to be a feasible option for VCE preparation with no significant adverse events.
• Combined coffee enema and PEG may enhance mid and distal small bowel visualization.
• Further prospective randomized trials are needed to confirm these findings and optimize VCE preparation.
