摘要

BACKGROUND Retrograde single balloon enteroscopy(SBE)is a minimally invasive procedure which is less frequently performed compared with antegrade SBE.There are few studies on the retrograde through-the-scope enteroscopy(TTSE),a novel technique for evaluation of the small bowel.AIM To compare the clinical utility and safety of retrograde TTSE with retrograde SBE.METHODS Clinical data and complications of retrograde TTSE(2014-2018)and retrograde SBE(2011-2018)performed in a community hospital were reviewed and presented as mean±SD or frequency(%)and compared using proper statistical tests.Technical success was defined as insertion of the enteroscope>20 cm beyond ileocecal valve.RESULTS Data obtained from 54 retrograde SBE in 49 patients and 27 retrograde TTSE in 26 patients were studied.The most common indication for retrograde enteroscopy was iron deficiency anemia(41 patients)followed by gastrointestinal bleeding(37 patients),and chronic diarrhea(7 patients).The duration of retrograde SBE procedure(91.9±34.2 min)was significantly longer compared with retrograde TTSE(70.5±30.7 min)(P=0.04).Technical success was comparable in TTSE[23/27(85.2%)]and SBE[41/54(75.9%)(P=0.33)].The mean depth of insertion beyond the ileocecal valve in retrograde SBE(92.5±70.0 cm)tended to be longer compared with retrograde TTSE(64.6±49.0 cm)(P=0.08).No complication was observed in this study.CONCLUSION Both retrograde TTSE and retrograde SBE are feasible and safe.Retrograde TTSE takes a shorter time and has a comparable technical success with SBE.TTSE has a lower capacity of small bowel insertion.
