Total Colonic Decompression After Colonoscopy Decreases Postcolonoscopy Abdominal Pain: A Randomized Double-Blind...

Area of Science:

• Gastroenterology
• Endoscopy
• Patient Outcomes

Background:

• Post-colonoscopy abdominal pain is a common patient complaint.
• Residual bowel gas is a primary suspected cause of this discomfort.

Purpose of the Study:

• To evaluate the efficacy of total colonic decompression in reducing post-colonoscopy abdominal pain.
• To assess the safety of the decompression procedure.

Main Methods:

• 300 patients undergoing colonoscopy were randomized into a decompression or control group.
• Decompression involved air aspiration after colonoscope withdrawal to the cecum.
• Abdominal pain was measured using a visual analogue scale (VAS) before discharge and 24-48 hours post-procedure.

Main Results:

• The decompression group showed a significantly lower incidence of abdominal pain (26.6%) compared to the control group (65.5%).
• Colonic decompression resulted in an 86.1% reduction in abdominal pain.
• Female gender and procedure duration over 800 seconds were independent factors for post-colonoscopy pain.

Conclusions:

• Total colonic decompression is an effective method for reducing post-colonoscopy abdominal pain.
• The procedure is safe and does not introduce new complications.
