    Introduction Serrated polyposis syndrome (SPS) increases colorectal cancer (CRC) risk. We describe the numbers of colonoscopies and polypectomies performed to achieve and maintain low polyp burdens, and the feasibility of expanding surveillance intervals in patients who achieve endoscopic control. Methods We retrospectively evaluated a prospectively collected database on 115 SPS patients undergoing surveillance at Indiana University Hospital between June 2005 and May 2018. The endoscopist provided surveillance interval recommendations based on polyp burden. Endoscopic control was considered successful if surveillance examinations exhibited fewer polyps and if no or only an occasional polyp ≥1 cm in size was present at follow-up. Initial control was designated the clearing phase and the maintenance phase was surveillance after control was established. Results In total, 87 patients (75.7%) achieved endoscopic control, with some others in the clearing phase at this writing. Achieving control required a mean of 2.84 colonoscopies (including the baseline) over 20.4 months and a mean total 27.9 polyp resections. After establishing control, 71 patients were recommended to receive ≥24-month follow-up. Of those, 60 patients (69.0% of patients with initial control) continued surveillance at our center. The mean interval between colonoscopies during maintenance was 19.3 months with 6.74 mean polypectomies per procedure on polyps primarily <1 cm. There were no incident cancers or colon surgeries during maintenance. Conclusion Most patients achieved control of polyp burden with 2 to 3 colonoscopies over 1 to 2 years. After reaching control, 60 patients returned at intervals up to 24 months with no incident cancers and no surgeries required. Expansion of surveillance intervals to 24 months is effective and safe for many SPS patients who reach control of polyp burden

    BACKGROUND: Efficiency is an important aspect of endoscopic practice that has received limited study. We evaluated the impact of scribing electronic pre-procedure history and physical examinations, and electronic procedure reports on endoscopist efficiency. METHODS: We used a stopwatch to measure the time between the procedures (scope out to scope in), pre-procedure patient assessment time, and procedure report generation time for 180 consecutive procedures performed by a single endoscopist with or without a scribe for recording history and physical and procedure reports. Schedulers were unaware of whether a scribe would be present. RESULTS: Mean times for recording the pre-procedure history and physical and procedure reports were reduced by 34% (p = 0.001) and 71% (p < 0.0001), respectively, when scribes were used. The mean time saved by the endoscopist from scribing the history and the physical and procedure reports was 2.12 and 1.59 min, respectively. When both processes were scribed, the endoscopist spent 42% (p = 0.033) longer in the recovery area (absolute mean increase 1.01 min) compared with when no scribes were utilized. The total time saved per 6.5-h procedure block with both scribes averaged to 41.7 min. CONCLUSION: The use of scribes to record history and physical examination notes and procedure reports saved enough endoscopist time to allow additional procedures or longer procedures, or to free the time for other tasks

    Objectives To determine the safety and effectiveness of the middle cranial fossa (MCF) approach in repairing spontaneous cerebrospinal fluid (sCSF) leaks. Study Design Retrospective cohort study. Methods Patient with sCSF leaks repaired by MCF approach between January 1, 2014 and August 31, 2019 were included. Demographic information, clinical and surgical findings, and postoperative outcomes were recorded. Results The cohort (n = 45) included 24 tegmen repairs by multilayer reconstruction using hydroxyapatite cement and 21 cases of multilayer repair without hydroxyapatite cement. Ten MCF repairs were performed on patients ≥65 years old. Twenty (53%) ears had multiple tegmen defects (range, 1–9 tegmen defects) and 78% of patients had ≥1 encephaloceles. All sCSF leaks were resolved with one surgical intervention. There were no major intracranial complications. Transient expressive aphasia occurred in 2 patients. Medical complications occurred in four patients. There were no short-term postoperative CSF leaks with bone cement reconstruction and two postoperative leaks without bone cement. One resolved with lumbar drain (LD) and the other resolved without treatment. The average (SD) length of stay (LOS) with bone cement was shorter than in patients without bone cement (2.54 [0.83] days vs. 3.52 [1.99] days, P < .05). There have been no long-term CSF leak recurrences with an average (SD) follow-up of 13.5 (12.9) months (range 0.25–46 months). Conclusions MCF approach for sCSF repairs demonstrate efficacious outcomes, particularly with tegmen reconstruction using hydroxyapatite cement. The approach exhibited no serious adverse events and few complications requiring intervention. Therefore, MCF is a safe and effective approach to resolve sCSF leaks

    SIC-8000 versus hetastarch as a submucosal injection fluid for endoscopic mucosal resection: a randomized controlled trial

    Background and Aims Viscous solutions provide a superior submucosal cushion for endoscopic mucosal resection (EMR). SIC-8000 (Eleview, Aries Pharmaceuticals, La Jolla, Calif) is a commercially available FDA approved solution but hetastarch is also advocated. We performed a randomized trial comparing SIC-8000 to hetastarch as submucosal injection agents for colorectal EMR. Methods This was a single-center double-blinded randomized controlled trial performed at a tertiary referral center. Patients were referred to our center with flat or sessile lesions measuring ≥15 mm in size. The primary outcome measures were the Sydney Resection Quotient (SRQ) and the rate of en bloc resections. Secondary outcomes were total volume needed for a sufficient lift, number of resected pieces, and adverse events. Results There were 158 patients with 159 adenomas (84 SIC-8000 and 75 hetastarch) and 57 serrated lesions (30 SIC-8000 and 27 hetastarch). SRQ was significantly better in the SIC-8000 group compared with hetastarch group (9.3 vs 8.1, p=0.001). There was no difference in the proportion of lesions with en bloc resections. The total volume of injectate was significantly lower with SIC-8000 (14.8 mL vs 20.6 mL, p=0.038) Conclusions SIC-8000 is superior to hetastarch for use during EMR in terms of SRQ and total volume needed, although the absolute differences were small

    Objective To compare differences in audiologic outcomes between slim modiolar electrode (SME) CI532 and slim lateral wall electrode (SLW) CI522 cochlear implant recipients. Study Design Retrospective cohort study. Setting Tertiary academic hospital. Methods Comparison of postoperative AzBio sentence scores in quiet (percentage correct) in adult cochlear implant recipients with SME or SLW matched for preoperative AzBio sentence scores in quiet and aided and unaided pure tone average. Results Patients with SLW (n = 52) and patients with SME (n = 37) had a similar mean (SD) age (62.0 [18.2] vs 62.6 [14.6] years, respectively), mean preoperative aided pure tone average (55.9 [20.4] vs 58.1 [16.4] dB; P = .59), and mean AzBio score (percentage correct, 11.1% [13.3%] vs 8.0% [11.5%]; P = .25). At last follow-up (SLW vs SME, 9.0 [2.9] vs 9.9 [2.6] months), postoperative mean AzBio scores in quiet were not significantly different (percentage correct, 70.8% [21.3%] vs 65.6% [24.5%]; P = .29), and data log usage was similar (12.9 [4.0] vs 11.3 [4.1] hours; P = .07). In patients with preoperative AzBio <10% correct, the 6-month mean AzBio scores were significantly better with SLW than SME (percentage correct, 70.6% [22.9%] vs 53.9% [30.3%]; P = .02). The intraoperative tip rollover rate was 8% for SME and 0% for SLW. Conclusions Cochlear implantation with SLW and SME provides comparable improvement in audiologic functioning. SME does not exhibit superior speech recognition outcomes when compared with SLW

    Impact of a ring fitted cap on insertion time and adenoma detection: a randomized controlled trial

    Background and Aims: Devices for flattening colon folds can improve polyp detection at colonoscopy. However, there are few data on the endoscopic ring fitted cap (EndoRings, EndoAid, Caesarea, Israel). We sought to compare adenoma detection with EndoRings with that of standard high-definition colonoscopy. Methods: A single-center randomized controlled trial of 562 patients (284 randomized to EndoRings and 278 to standard colonoscopy) at 2 outpatient endoscopy units in the Indiana University Hospital system. Adenoma detection was the primary outcome measured as adenoma detection rate (ADR) and adenomas per colonoscopy (APC). We also compared sessile serrated polyp detection rate (SSPDR), insertion times, withdrawal times, and ease of passage through the sigmoid colon. Results: EndoRings was superior to standard colonoscopy in terms of APC (1.46 vs 1.06, p=0.025) but there were no statistically significant differences in ADR or SSPDR. Mean withdrawal time (in patients with no polyps) was shorter and insertion time (all patients) was longer in the EndoRings arm by 1.8 minutes and 0.75 minutes, respectively. One provider had significantly higher detection with EndoRings and contributed substantially to the overall results. Conclusions: EndoRings can increase adenoma detection without significant increase in procedure time, but the effect varies between operators. EndoRings slows colonoscope insertion
