Post-operative cognitive dysfunction in patients following gastrointestinal endoscopic treatment.
Applied Neuropsychology. Adult 2023 January 20
We aimed to explore the changes in post-operative cognitive dysfunction (POCD) after gastrointestinal endoscopic treatment using detailed neuropsychological assessments. Patients hospitalized for gastrointestinal endoscopic polypectomy were recruited for neuropsychological evaluations, which included the Chinese version of the Mini-Mental State Examination (MMSE), Auditory-Verbal Learning Test, Digit Span Test (DST), Trail Making Task (TMT), Verbal Fluency Test, Clock Drawing Test, and Stroop test. Cognitive assessments were performed twice: one day before and 24 h after treatment. Healthy control subjects participated in the neuropsychological assessment during the same intervals. Detailed cognitive assessments were performed for 40 patients and 60 control subjects. Based on the Z scores, the incidence of POCD 24 h after gastrointestinal endoscopic treatment was 20%. Patients with POCD had significant impairment in the post-operative MMSE, forward DST, TMT, and Stroop interference effect correct count tests (all p < 0.05). Our preliminary results showed that patients were not fully recovered, and 20% had impairment in multiple cognitive assessments 24 h after a gastrointestinal endoscopy. As attention was affected, safety while discharging those patients should be a concern.
