Limited low-air insufflation is optimal for colonoscopy

Area of Science:

• Gastroenterology
• Endoscopy

Background:

• Air insufflation is critical for colonoscopy but optimal levels are not well-defined.
• This study aimed to determine the best air insufflation strategy for colonoscopic examinations.

Purpose of the Study:

• To identify optimal air insufflation levels during colonoscopy.
• To evaluate the impact of different insufflation strategies on procedure efficiency and patient comfort.

Main Methods:

• Colonoscopies were randomized into three groups: high-air, low-air, and limited low-air insufflation (rectum/sigmoid only).
• Evaluated outcomes included completion rate, cecal intubation time, propofol dose, need for abdominal compression, and post-procedure bloating.

Main Results:

• Completion rates were similar across all groups.
• Limited low-air insufflation (Group C) showed a significantly shorter cecal intubation time compared to standard low-air (Group B).
• Group C required less abdominal compression and reported significantly less post-procedure bloating compared to Groups A and B.

Conclusions:

• Limited low-air insufflation in the rectum and sigmoid colon is the preferred method for colonoscopy.
• This technique enhances patient comfort and procedural efficiency.
