Quality indicators for colonoscopy in a Tunisian endoscopy unit

Area of Science:

• Gastroenterology
• Endoscopy
• Colorectal Cancer Screening

Background:

• Colonoscopy is crucial for colorectal cancer prevention and early diagnosis.
• Procedure effectiveness relies on quality indicators like cecal intubation and adenoma detection rates.
• Evaluating these quality indicators is essential for optimizing colonoscopy performance.

Purpose of the Study:

• To assess key colonoscopy quality indicators in a Tunisian endoscopy center.
• To analyze factors influencing cecal intubation rate (CIR) and polyp detection rate (PDR).

Main Methods:

• Retrospective study of 859 colonoscopies performed between January 2009 and March 2013.
• Data collected included demographics, indications, and endoscopic findings.
• Quality indicators analyzed: cecal intubation rate (CIR) and polyp detection rate (PDR), with bowel preparation quality assessed subjectively.

Main Results:

• The cecal intubation rate (CIR) was 61.1%, influenced by bowel preparation quality and screening indication.
• Polyp detection rate (PDR) was 21%, associated with patient age, male gender, bowel preparation, presence of colorectal cancer, and screening indication.
• Multivariate analysis identified bowel preparation quality and screening indication as independent predictors for CIR, and age, bowel preparation, and screening indication for PDR.

Conclusions:

• Bowel preparation quality and procedure tolerance are significant factors affecting colonoscopy quality indicators.
• Improving bowel preparation and patient tolerance are key strategies to enhance colonoscopy performance.
• These findings emphasize the importance of optimizing procedural factors for better colorectal cancer screening outcomes.
