If the Right Side of the Colon Deserves Double Examination, so Does the Rectum
Douglas K. Rex, MD, MASGE, reviewing Troelsen FS, et al. Clin Gastroenterol Hepatol 2023 Apr 7.
This study used the World Endoscopy Organization classification of postcolonoscopy colorectal cancer (PCCRC) to assess 762 PCCRC cases that accumulated during 1995 to 2021.
PCCRC was located in the cecum in 15.2% of patients, the ascending colon in 15.7%, and the rectum in 23%. Overall, 81% of PCCRC cases were classified as category A, which is a possible missed lesion with an adequate prior examination (complete to the cecum with good or excellent preparation). The fraction attributed to incomplete resection of a previously identified lesion was 11%, with some reduction over time.
