Changing from two‐ to one‐operator colonoscopy insertion technique is feasible with similar quality outcomes

BACKGROUND AND AIM: Colonoscopy can be performed with two‐operator (2OP) or one‐operator (1OP) methods. This study aimed to investigate the feasibility and colonoscopy quality outcomes for the two different colonoscopy insertion techniques. METHODS: One colonoscopist from Changhua Christian Hospital...

Sumario:BACKGROUND AND AIM: Colonoscopy can be performed with two‐operator (2OP) or one‐operator (1OP) methods. This study aimed to investigate the feasibility and colonoscopy quality outcomes for the two different colonoscopy insertion techniques. METHODS: One colonoscopist from Changhua Christian Hospital learned and changed the colonoscopy insertion technique from 2OP to 1OP during 2013. Real‐life results of screening colonoscopies performed by this colonoscopist between these two insertion techniques (year 2012: 2OP vs year 2014: 1OP) were retrospectively reviewed and compared. RESULTS: In total, 219 screening colonoscopies were reviewed (2OP group, n = 103 vs 1OP group, n = 116). No differences were noted between both groups in terms of patient age, gender, weight, and height. The overall cecum intubation was 98.2%, adenoma detection rate (ADR) was 29.7%, and colonoscopy withdrawal time was 518.58 ± 972.04 s. On comparing colonoscopy quality outcomes between both methods, no differences were observed in cecal intubation rates (2OP vs 1OP: 100 vs 96.6%, P = 0.1626), ADR (28 vs 31%, P = 0.7401), and colonoscopy withdrawal time (454.88 ± 178.21 vs 576.92 ± 1325.01 s, P = 0.355). However, the 1OP group demonstrated significantly shorter colonoscopy insertion time (2OP vs 1OP: 298.28 ± 202.95 vs 216.21 ± 121.99 s, P = 0.003). CONCLUSION: Colonoscopy quality outcomes were not impaired when one endoscopist changed the colonoscopy practice pattern from 2OP to 1OP. However, 1OP significantly shortened the colonoscopy insertion time.
