Colonoscopy in the young: An indication-based analysis of outcome.

BACKGROUND

Data on colonoscopy's diagnostic yield in young adults with lower gastrointestinal symptoms are scarce. We evaluated this yield in young patients by performing an indication-based analysis of outcomes.

METHODS

We reviewed diagnostic colonoscopies performed in young adults (age <50 years) over 10 years. We created two groups of young adults (18-39 years, n = 4941) and quadragenarians (40-49 years; n = 6605), included a control group of average-risk patients referred for screening colonoscopies during the same period (50-60 years, n = 1453). We evaluated clinical indications for colonoscopies among the young and performed an indication-based analysis of patients' outcomes.

RESULTS

Chronic diarrhea and abdominal pain (42.4 and 36.2%), rectal bleeding (19.8 and 18.4%), and constipation were major indications for colonoscopy performance in quadragenarian and younger patients, respectively. Overall, diverticulosis (8.7 vs 1.3 and 3.9%; p

CONCLUSION

We outlined the expected diagnostic yields of colonoscopy performed in young patients for multiple indications, showing that rectal bleeding was consistently associated with CRC and polyp detection.
