Esophagogastroduodenoscopy-assisted bowel preparation for colonoscopy

Area of Science:

• Gastroenterology
• Endoscopy
• Clinical Trials

Background:

• Effective bowel preparation is crucial for successful colonoscopy.
• Conventional split-dose polyethylene glycol (PEG) regimens can be challenging for inpatients to tolerate.
• Esophagogastroduodenoscopy (EGD) offers a potential route for improved bowel preparation delivery.

Purpose of the Study:

• To compare the quality and tolerance of EGD-assisted bowel preparation versus conventional split-dose PEG for inpatient colonoscopy.

Main Methods:

• A randomized controlled trial involving hospitalized patients undergoing colonoscopy after EGD.
• Patients received either EGD-assisted PEG (2L endoscopically, 1L orally) or conventional PEG (2L evening prior, 1L morning of).
• Primary outcomes included bowel preparation quality and patient tolerance.

Main Results:

• EGD-assisted PEG resulted in superior bowel preparation quality (4.1 vs 6.5, P = 0.0005).
• Seventy-four percent of patients tolerated EGD-assisted PEG well, compared to 46% for conventional PEG (P = 0.0133).
• EGD-procedural time increased (24 vs 15 min, P < 0.0001), with no difference in sedation or adverse events.

Conclusions:

• EGD-assisted administration of PEG solution improves bowel preparation quality and patient tolerance in selected hospitalized patients.
• This method offers a viable alternative to conventional split-dose regimens for inpatient colonoscopy.
• Further research may explore broader application and optimization of this technique.
