Kolonoskopi Sırasında Hasta Pozisyonunun Değiştirilmesinin Kolonoskopi Süresi, İleal Entübasyon Oranı Ve Polip Sayısına Etkisi

Abstract

Objective: Colonoscopy is universally considered as the conventional tool for the identification and removal of adenomatous polyps. The aim was to evaluate the effect of position change on the cecal and ileal intubation rates and the detection rate of polyps. In this way, it is aimed to accelerate the colonoscopy procedure time and increase its sensitivity. Methods: The study included 943 patients aged between 17 and 90 years presented for a diagnostic colonoscopy at our hospital surgery clinic from January 2008 to December 2018. Results: The results indicated significantly lower median cecal and ileal intubation time and higher polyps detection rate owing to change in the patient’s posture to supine than in the left lateral position during colonoscopy procedure (p<0.0001). Moreover, cecal (p<0.0001) and ileal (p=0.001) intubation time was negatively correlated with the number of polyps detected. The age of the participating patients was the demographic factor found to be positively correlated with the number of polyps detected (p<0.0001). Furthermore, changing the patient’s posture to supine led to an 11% increase in the polyp detection rate in the cecum, ascending colon, and hepatic flexure combined regions (p<0.0001). The odds of detection of polyps in this region were 2.11 (95%CI, 1.60-2.78) times higher in supine posture compared to the left lateral position. Conclusion: The above findings strengthen the relevance of the position of the patient in the polyp detection rate during colonoscopy procedures.
