AI Article Synopsis
- Gastroenterologists often rate the appropriateness of their own colonoscopies significantly higher than an expert panel, with an average score of 7.2 compared to the panel's 5.4.
- Among the 6004 patients assessed, there was a notable variance in how both groups classified colonoscopy indications, indicating disagreement in their evaluations.
- The study suggests that improving alignment between gastroenterologists' assessments and expert guidelines could help in better determining the necessity of colonoscopies and reducing their overuse.
Article Abstract
Background And Study Aim: Little is known about how gastroenterologists perceive the appropriateness of colonoscopies they perform. The objective of this study was to compare the appropriateness and necessity of colonoscopies as assessed by an expert panel and by the gastroenterologists performing the colonoscopies.
Methods: This observational study included 21 centers in 11 countries. Patients referred for colonoscopy were consecutively included. Appropriateness and necessity of colonoscopies were independently rated on a 9-point scale by the gastroenterologists performing them and by an expert panel using a validated method (RAND). The differences between the ratings from the two groups were examined.
Results: 6004 patients were included in the study. Comparisons of ratings were possible for 5381 (89.6 %) patients. The gastroenterologists' mean appropriateness rating was 7.2 +/- 1.7, and the panel's mean appropriateness rating was 5.4 +/- 2.3 ( P < 0.001). The percentages of indications rated inappropriate, uncertain, appropriate, and necessary were 4.1 %, 23.8 %, 14.2 %, and 58.0 % for the gastroenterologists and 27.2 %, 26.7 %, 25.0 %, and 21.1 % for the panel, respectively. Agreement between the two groups' ratings was poor (28.8 %, kappa = 0.11). Differences between the two groups' ratings decreased with increasing patient age, decreasing health status, and decreasing expertise level of the referring physician. However, the gastroenterologists produced consistently higher ratings.
Conclusions: Compared with an expert panel, gastroenterologists tend to overestimate the appropriateness of colonoscopies they perform. Except for well-delineated reasons, participating gastroenterologists weighed patient characteristics differently from the panel when judging appropriateness. Ways to increase the prospective use of appropriateness criteria in order to improve appropriateness and reduce overuse of colonoscopies should be examined further.

In this manuscript, I comment on the article by Pospisilova published in the recent issue of the journal, in which selective embolization was used to treat anorectal hemangioma, a rare disease causing lower gastrointestinal bleeding. Anorectal hemangioma can easily be mistaken; for example, the patient in this case was previously misdiagnosed with ulcerative colitis. Choosing the appropriate tests and understanding the typical manifestations of anorectal hemangioma under colonoscopy, computerized tomography, magnetic resonance imaging and other tests are beneficial for diagnosis.

Familial adenomatous polyposis (FAP) is an autosomal dominant hereditary disease characterized by the progressive development of multiple adenomatous polyps along the colon. The majority of individuals develop colorectal cancer by the age of 40 within the evolutionary course of the disease. For this reason, screening family members is essential to enable identification, surveillance, and appropriate intervention.

Bile salts are biosurfactants released into the intestinal lumen which play an important role in the solubilisation of fats and certain drugs. Their concentrations vary along the gastrointestinal tract (GIT). This is significant for implementation in physiologically based pharmacokinetic (PBPK) modelling to mechanistically capture drug absorption.
