Same-day bidirectional endoscopy (BDE) is a commonly performed procedure, but the optimal sequence for the procedure with moderate conscious sedation is not well established. This study investigated the optimal sequence for same-day BDE under moderate conscious sedation and carbon dioxide insufflation in terms of sedation doses, patient discomfort, and colonoscopy performance.A prospective randomized controlled study of 120 patients who were scheduled for BDE examination was performed. Colonoscopy followed by esophagogastroduodenoscopy (EGD) examination was performed in 60 patients (colonoscopy-EGD group), and EGD followed by colonoscopy examination was performed in another 60 patients (EGD-colonoscopy group). Endoscopists and patients completed a questionnaire to assess objective and subjective discomfort.Baseline demographics, procedure indications, bowel preparation quality, cecal intubation rate/time, colonoscopy withdrawal time, endoscopic interventions, BDE procedure time, colon polyp/adenoma detection rates, patient discomfort, and adverse events were similar between the two study groups. The total doses of fentanyl and midazolam were significantly higher for the colonoscopy-EGD group than for the EGD-colonoscopy group (83.4 ± 17.7 vs 68.7 ± 18.6 μg and 6.3 ± 1.4 vs 5.2 ± 1.3 mg, P 0.0001 and P 0.0001, respectively). The recovery time to discharge was significantly longer for the colonoscopy-EGD group than for the EGD-colonoscopy group (43.5 ± 16.2 vs 34.5 ± 8.9 min, P = 0.0003).Esophagogastroduodenoscopy followed by colonoscopy is the optimal sequence for same-day BDE under moderate conscious sedation and carbon dioxide insufflation. Following this order allows for a reduction of sedation doses and for shorter recovery times. |
