THE DIAGNOSTIC YIELD OF ILEAL INTUBATION DURING COLONOSCOPY AMONG PATIENTS WITH GASTROINTESTINAL COMPLAINTS

Aims Ileal intubation and biopsy are considered as a main method for diagnosis of IBD, enteropathy and etc, nevertheless there is no definite recommendation for routinely ileal intubation during colonoscopy in patients without IBD suspicion. The aim of this study was to evaluate necessity of terminal ileum intubation during endoscopy among patients with GI complaints but without IBD suspicion.

Methods We performed 1100 colonoscopy under intravenous sedation between October 2018 and November 2019. The examination was performed using Olympus CV 170 and Olympus CV 190 Plus and NBI technique was used. 95% of patients were prepared with PEG and all patients had complaints meteorism, diarrhea, constipation, abdominal pain etc.

Almost 100% cases were performed successful ileal intubation excluding oncological obstructions. In 90% cases duration of intubation was about 1 minute, in 10% cases maximum duration was 5 minutes.

Results The terminal ileum was successfully intubated in 1092 patients . Isolated ileal lesions were present in 54 cases (5%) and biopsy was taken for each patient. The various abnormalities were found erosions, ulcers, polypoid lesions, villous atrophy, cobblestone mucosa etc. In 34 cases (3,2%) macroscopic abnormalities were present both in ileum and colon. Additionally, the information about previous ileal pathologies were in less than 20 % cases.

Conclusions Ileal intubation during colonoscopy find out isolated ileal pathologies in 5% cases and it is 1,58 times more than combined ileal and colonic pathologies. Therefore, there are no significant waste of time or difficulties for ileal intubation, but outcome is more valuable.
