LONGER CECUM INSERTION TIME AND MORE INADEQUATE COLONIC PREPARATION IN PATIENTS WITH ACROMEGALY: IS A DIFFERENT COLONOSCOPY PREPARATION NEEDED?

Abstract

Purpose. To investigate whether there is a difference between acromegalic and non-acromegalic cases in terms of bowel preparation and colonoscopic intervention. Methods. Patients with controlled and uncontrolled acromegaly and as a control group (CG) patients without acromegaly between January 2010 and March 2014 were included. Groups were compared regarding adequacy of bowel preparation, cecal insertion time (CIT) and colonoscopy results. Results. Fifty-nine patients with acromegaly (controlled n=30, uncontrolled n=29) and 73 age and gender matched volunteers without acromegaly were evaluated. CIT in cases with controlled, uncontrolled acromegaly cases and in CG was 5.33 {[}4.00-6.00], 7.00 {[}4.91-11.31], and 3.10 {[}2.35-4.65] minutes, respectively (p<0.001). Cases in CG had shorter CIT compared to controlled and uncontrolled acromegaly cases ( p=0.014 and p<0.001, respectively). There was no significant difference regarding CIT between controlled and uncontrolled acromegaly cases (p=0.247). Six (20\%) of controlled acromegaly patients, 10 (35\%) of uncontrolled acromegaly patients and three (4\%) of CG had inadequate bowel cleansing (p<0.001). Although statistically insignificant, cases with inadequate bowel cleansing had tendency towards having prolonged CIT in comparison to cases with adequate bowel cleansing (6.00 {[}3.87-9.00] and 4.16 {[}2.95-5.70] minutes, respectively, p=0.07). Conclusion. Inadequate bowel cleansing is one of the main problems encountered during colonoscopic investigation/surveillance in acromegalic patients. Therefore, a different protocol for colonoscopy preparation may be needed for these cases.
