For anyone who has undergone a colonoscopy, the most dreaded part is often the preparation—drinking liters of laxative solution, enduring hours of discomfort, and hoping the cleanse is thorough enough for an accurate procedure. But what if there were a better way?
A study from Danbury Hospital presented at the American College of Gastroenterology (ACG) Annual Scientific Meeting has shed light on an alternative that outperforms traditional bowel prep methods: colon hydrotherapy (CHT).
Study Findings: Hydrotherapy vs. Traditional Bowel Prep
The study compared same-day colon hydrotherapy (CHT) with two conventional bowel prep methods:
- Polyethylene glycol-electrolyte lavage (PEG-ES) – A large-volume laxative solution often prescribed for colonoscopy prep.
- Aqueous sodium phosphate (ASP) – A smaller-volume prep but associated with potential electrolyte imbalances.
Effectiveness of Cleansing
Endoscopists evaluated the quality of bowel cleansing in different sections of the colon and found:
- Right colon: 92% of CHT patients had a “good” cleanse, compared to 62% (ASP) and 49% (PEG-ES).
- Transverse colon: 100% of CHT patients had a “good” cleanse, compared to 80% (ASP) and 63% (PEG-ES).
- Left colon: 98% of CHT patients had a “good” cleanse, compared to 84% (ASP) and 67% (PEG-ES).
Patient Experience
Colon prep is not just about effectiveness—it’s also about comfort and compliance. Patients in the study were asked to rate their experience based on ease, convenience, and comfort:
- Ease of preparation: 96% of CHT patients rated it as easy, compared to 87% (ASP) and 56% (PEG-ES).
- Convenience: 98% of CHT patients found it convenient, compared to 61% (ASP) and 79% (PEG-ES).
- Comfort: 94% of CHT patients reported a comfortable experience, compared to 71% (ASP) and 36% (PEG-ES).
Perhaps the most telling statistic? When asked if they would choose a different prep for their next colonoscopy, only 4% of CHT patients wanted a different method—compared to 48% (ASP) and 60% (PEG-ES).
Why Colon Hydrotherapy is a Game-Changer
1. More Effective Cleansing
CHT achieves superior cleansing across all sections of the colon. Traditional prep methods rely on the patient’s ability to drink enough solution and tolerate the discomfort, which can lead to incomplete cleansing. Hydrotherapy, by contrast, directly flushes the colon with warm water, ensuring a thorough cleanse.
2. Greater Patient Comfort
The biggest complaint about PEG-ES and ASP is the discomfort—nausea, bloating, cramping, and diarrhea. CHT eliminates the need for excessive liquid consumption and is gentle on the digestive system, making the process far more tolerable.
3. Same-Day Convenience
Colon hydrotherapy can be performed on the same day as the colonoscopy, reducing the disruption to a patient’s routine. Traditional preps require hours (if not an entire day) of preparation, often making it difficult for people with busy schedules.
4. Higher Compliance Rates
One of the biggest challenges in colonoscopy screening is patient compliance—many people avoid the procedure due to the difficulty of prep. Since hydrotherapy is easier and more comfortable, more people may be willing to undergo routine screenings, leading to earlier detection and prevention of colorectal diseases.
Final Thoughts
This study strongly suggests that colon hydrotherapy is a superior alternative to traditional colonoscopy prep methods. It provides better cleansing, greater comfort, and higher patient satisfaction—a win-win for both patients and physicians.
As awareness grows, we may see colon hydrotherapy become a mainstream option for colonoscopy preparation. If you’re due for a colonoscopy, ask your healthcare provider whether CHT is available as an option.
