Exploring intraprocedural performance in colonoscopy: Insights from a tertiary care center in Saudi Arabia.

Abstract

Background: Colonoscopy is essential for diagnosing and managing colorectal conditions, and is recognized as the gold standard for early cancer detection and removal of precancerous lesions. The American Society for Gastrointestinal Endoscopy and the American College of Gastroenterology have established benchmark indicators to minimize the risk of interval colorectal cancer. Despite their importance, research on these metrics in Saudi Arabia is limited. This study analyzes key intraprocedural indicators of colonoscopies at a tertiary care center to evaluate adherence to care standards.

Methods: This retrospective study examined 3763 colonoscopies conducted by adult gastroenterologists at Johns Hopkins Aramco Healthcare from January 2021 to December 2022. Procedures were categorized as screening and non-screening, with demographic data collected alongside withdrawal time (WT), cecal intubation rate (CIR), polyp detection rate (PDR), adenoma detection rate (ADR), Boston Bowel Preparation Scale (BBPS), polyp retrieval rate, rectal retroflexion, and adverse events.

Results: The mean age of participants was 54.13 years, with 81.56% of them Saudis and 44.6% female. The average WT was 10 min. The overall CIR was 93.6% (94.78% for screening), with a PDR of 33.9% and a retrieval rate of 96.6%. ADR for screening participants was 25.63%, and 88.94% of participants achieved a BBPS score of 6 or more. The adverse event rate was at 0.2%, primarily due to bleeding.

Conclusions: The study indicates that colonoscopy procedures adhere to care standards, with ADR among male screening patients approaching 30%. Further research is necessary to evaluate pre- and post-procedural indicators.
