Area of Science:

  • Gastroenterology
  • Medical Technology

Background:

  • Colonoscopy is crucial for managing colorectal diseases, including prevention, diagnosis, and treatment.
  • Technological advancements have expanded the applications of colonoscopy.
  • As an invasive procedure, colonoscopy carries risks requiring specialist expertise.

Purpose of the Study:

  • To report on the authors' experience with 1,234 colonoscopies.
  • To analyze indications, bowel preparation effectiveness, and complication rates.

Main Methods:

  • Review of 1,234 colonoscopies performed by specialists.
  • Analysis of patient indications, bowel preparation methods (10% mannitol), and outcomes.
  • Documentation of complications such as perforation and bleeding post-polypectomy.
