Outcomes of use of electromagnetic guidance with responsive insertion technology (RIT) during colonoscopy: a prospective randomized controlled trial.

Background and study aims Colonoscopy can be technically challenging and cause discomfort in patients. The integrated Scope Guide assist is built in to show that with its use outcomes are improved during colonoscopy. We aimed to test the usefulness of the Magnetic Scope Guide Assist (ScopeGuide ) with respect to cecal intubation time, and other procedural quality outcomes. Patients and methods We conducted a prospective study of outpatients undergoing elective colonoscopy at the endoscopic units of the University of Alabama at Birmingham (UAB) from March 2016 to July 2016. Patients were randomly assigned in a 1:1 block design to groups that either had standard colonoscopy or Scope-guided colonoscopy. The primary outcome measure was cecal intubation time (CIT). Secondary outcome measures included use of manual pressure, position changes for cecal intubation and sedation requirements. Results Three hundred patients were randomized to either group; standard (n = 150) vs. Scope-guided (n = 150). The mean CIT was not statistically different for the standard and the Scope-guided groups (4.6 vs. 4.3 minutes; P  = 0.46). There were also no statistical differences in frequency of manual pressure applied (16.7 % for Scope-guided vs. 19.1 % for standard; P  = 0.65) or position changes (11.4 % for scope guided vs. 8.8 % standard; P  = 0.56). Sedation requirements showed lesser use of midazolam (3.9 mg vs. 4.7 mg, P  = 0.003) in the Scope-guide group, while there was no significant difference in use of fentanyl (fentanyl - 62.1 mg vs. 68.9 mg, P  = 0.09 similar between groups, for Scope-guided vs. standard groups, respectively). Adverse events were similar in both groups. Conclusions In patients undergoing routine elective colonoscopy, use of ScopeGuide by experienced colonoscopists did not improve CIT or affect the frequency of ancillary maneuvers. The benefit of this device during training of endoscopists could be considered for further studies.

Predictors for outcomes and readmission rates following double balloon enteroscopy: a tertiary care experience.

AIM: The objectives of this study are to examine clinical characteristics of patients undergoing anterograde and retrograde double balloon enteroscopy (DBE) and to assess factors predicting positive diagnostic yield, therapeutic yield, and readmission. METHODS: We conducted a retrospective cohort study of patients (n = 420) who underwent DBE at a tertiary care center between 2012 and 2016 at a tertiary referral center. Measures of central tendency and frequency distributions were used for univariate analysis. Chi-square and t-test analyses were used to compare patient characteristics. Logistic regression was used to predict outcomes of interest. RESULTS: Of patients included in the study, 59 % were male with a mean age of 61.49 (SD = 15.15) Altered anatomy was noted in 14 %, while 5 % and 13 % of patients had end stage renal disease (ESRD) and current use of anticoagulation, respectively. The most common indication for DBE was obscure gastrointestinal bleed (OGIB) (33 %). Forty-nine patients had obscure and overt gastrointestinal bleeding (GIB) and 22 % had occult GIB with iron deficiency. The cohort's rate of positive diagnostic yield was 73 % and 35 % for therapeutic yield. The 30-day and 6-month readmission rates were both 11 %. A higher proportion of those readmitted were male (75 % vs 57 %, P  = 0.027) and had longer procedural time (38.68 vs 46.57, P  = 0.011). Likewise, occult GIB with iron deficiency anemia and iron deficiency alone (OR = 2.45, CI: 1.233 - 4.859, P  = 0.011), inpatient status (OR 2.42, CI 1.344 - 4.346, P  = 0.003), and longer procedural time (OR = 1.02, CI: 1.004 - 1.029, P  = 0.008) were associated positively with readmission. CONCLUSION: DBE procedures have relevant efficacy for both diagnostic and therapeutic yield while evaluating small bowel disease. Readmission rates are low and more in those with GI bleed and iron deficiency with longer index procedural times.
