ABSTRACT
INTRODUCTION: Shankhaprakshalana (SP) is a yogic method aiming to cleanse the bowel. It involves the use of warm saline water and a combination of five asanas. This study was designed to assess the effectiveness and safety of bowel preparation by SP. METHODS: This is a retrospective observational study of prospectively collected data. Patients planned for colonoscopy were screened and enrolled to undergo bowel preparation by SP on the day of the colonoscopy. Patients having comorbid conditions, poor performance status, suspected or previously diagnosed intestinal stricture and past history of major abdominal surgery and those unable to perform asanas of SP were excluded. A low-fiber diet was advised for one day before the colonoscopy. Patients were advised to drink 400 mL of lukewarm saline water followed by five asanas (exercises) of SP, each done eight times dynamically and sequentially. After completing six such cycles, patients underwent colonoscopy. Boston Bowel Preparation Scale (BBPS) score was used to assess the quality of bowel preparation. RESULTS: Total 238 patients were included. The major indications for colonoscopy were abdominal pain (35.3%), hematochezia (23.9%), diarrhea (20.2%), constipation (10.9%) and anemia (9.7%). The mean age was 37.7 (± 12) years. The mean BBPS was 8 (± 1.2). Bowel preparation was inadequate (BBPS < 6) in only two patients. Mean segmental BBPS for the three segments of the colon (right, transverse and left) was 2.6 (± 0.5), 2.7 (± 0.4) and 2.6 (± 0.7), respectively. Minor adverse events (nausea, abdominal pain, vomiting, giddiness and bloating) were noted in 10 participants (4.2%), which did not require hospitalization. Bowel preparation was completed in 133 (± 35) minutes. CONCLUSION: Shankhaprakshalana is an effective and safe method to achieve adequate bowel preparation before colonoscopy. Since this is a single-center and retrospective study, future multi-centric, prospective studies comparing it with the standard bowel preparation regimens are warranted.
