RESUMO
The ability of a colonoscopist to detect colon polyps is commonly measured by the adenoma detection rate (ADR). The outcome of colonoscopy varies based on ADR, and the relationship between decreasing provider ADR and the increased risk of subsequent fatal colorectal cancer has been clearly established.1 Despite the importance of provider ADR, it is of limited value at lower provider volumes due to imprecise measurements. We have previously shown that ratings of colonoscopy inspection quality (CIQ) from video-taped colonoscopies by experts highly correlate with provider ADR, and can provide colonoscopists with specific techniques in need of remediation.2 It is unclear, however, whether these video-based evaluations are a feasible method of assessing colonoscopy quality due to a reliance upon expert evaluations. The primary aim of this study was to determine whether video-based assessments of colonoscopy inspection quality by colonoscopy-naïve raters (novice raters) correlate with assessments by expert raters and with established colonoscopy quality metrics.

BACKGROUND/GOALS: Inpatient colonoscopy preparations are often inadequate, compromising patient safety and procedure quality, while resulting in greater hospital costs. The aims of this study were to: (1) design and implement an electronic inpatient split-dose bowel preparation order set; (2) assess the intervention's impact upon preparation adequacy, repeated colonoscopies, hospital days, and costs. STUDY: We conducted a single center prospective pragmatic quasiexperimental study of hospitalized adults undergoing colonoscopy. The experimental intervention was designed using DMAIC (define, measure, analyze, improve, and control) methodology. Prospective data collected over 12 months were compared with data from a historical preintervention cohort. The primary outcome was bowel preparation quality and secondary outcomes included number of repeated procedures, hospital days, and costs. RESULTS: On the basis of a Delphi method and DMAIC process, we created an electronic inpatient bowel preparation order set inclusive of a split-dose bowel preparation algorithm, automated orders for rescue medications, and nursing bowel preparation checks. The analysis data set included 969 patients, 445 (46%) in the postintervention group. The adequacy of bowel preparation significantly increased following intervention (86% vs. 43%; P<0.01) and proportion of repeated procedures decreased (2.0% vs. 4.6%; P=0.03). Mean hospital days from bowel preparation initiation to discharge decreased from 8.0 to 6.9 days (P=0.02). The intervention resulted in an estimated 1-year cost-savings of $46,076 based on a reduction in excess hospital days associated with repeated and delayed procedures. CONCLUSIONS: Our interdisciplinary initiative targeting inpatient colonoscopy preparations significantly improved quality and reduced repeat procedures, and hospital days. Other institutions should consider utilizing this framework to improve inpatient colonoscopy value.

BACKGROUND AND AIMS: Endoscopic resection (ER) is a safe and effective treatment for nonmalignant complex colorectal polyps (complex polyps). Surgical resection (SR) remains prevalent despite limited outcomes data. We aimed to evaluate SR outcomes for complex polyps and compare SR outcomes to those of ER. METHODS: We performed a single-center, retrospective, cohort study of all patients undergoing SR (2003-2013) and ER (2011-2013) for complex polyps. We excluded patients with invasive carcinoma from the SR cohort. Primary outcomes were 12-month adverse event (AE) rate, length of stay (LOS), and costs. SR outcomes over a 3-year period (2011-2013) were compared with the overlapping ER cohort. RESULTS: Over the 11-year period, 359 patients (mean [± SD] age 64 ± 11 years) underwent SR (58% laparoscopic) for complex polyps. In total, 17% experienced an AE, and 3% required additional surgery; 12-month mortality was 1%. Including readmissions, median LOS was 5 days (IQR 4-7 days), and costs were $14,528. When an AE occurred, costs ($25,557 vs $14,029; P < .0001) and LOS (11 vs 5 days; P < .0001) significantly increased. From 2011 to 2013, 198 patients were referred for ER, and 73 underwent primary SR (70% laparoscopic). There was a lower AE rate for ER versus primary SR (10% vs 18%; P = .09). ER costs (including rescue SR, when required) were lower than those of primary SR ($2152 vs $15,264; P < .0001). CONCLUSIONS: AEs occur in approximately one-sixth of patients after SR for complex polyps. ER-accounting for rescue SR caused by malignancy, AEs, or incomplete resection-is associated with markedly lower costs than SR. These data should be used when counseling patients about treatment options for complex polyps.

INTRODUCTION: Colonoscopies and fecal immunochemical tests (FITs) are the preferred modalities for colorectal cancer (CRC) screening. In addition to proper patient selection, appropriate fecal immunochemical testing requires that negative tests be repeated annually, positive tests lead to a diagnostic colonoscopy, and FIT not be performed within 5 years of a colonoscopy with adequate bowel preparation. We sought to study the frequency of inappropriate FITs at the Veterans Affairs Pittsburgh Health Care System in Pennsylvania. METHODS: A retrospective quality assurance study was undertaken of veterans undergoing FIT in a 3-year period (2015-2017). We calculated the rate of a negative initial FIT in 2015/2016 followed by a second FIT in 2016/2017 in a random selection of veterans (3% SE, 95% CI). Demographics were compared in an equal random number of veterans that did and did not have a follow-up FIT (5% SE, 95% CI of all negative FIT). We also calculated the rate of completing colonoscopy following a positive FIT in a random selection of veterans (3% SE, 95% CI). Finally, we investigated use of FIT following a colonoscopy for all veterans in the study period. RESULTS: A total of 6,766 FITs were performed; 4,391 unique veterans had at least 1 negative FIT, and 709 unique veterans had a positive FIT. Of 1,742 veterans with at least 1 negative FIT, 870 were eligible for repeat testing during the study period, and only 543 (62.4%) underwent at least 2 FITs. There was no significant demographic difference in veterans that had only 1 or at least 2 FITs. Of 410 veterans with a positive FIT, 113 (27.5%) did not undergo a subsequent colonoscopy within 1 year due to patient refusal, or failure to schedule or keep a colonoscopy appointment. Of 832 veterans who had both a FIT and colonoscopy in the interval, 108 veterans underwent colonoscopy with a subsequent FIT (1.6% of total FITs performed). Of these, 95 (88%) were judged to be inappropriate. Thirteen instances of FIT following colonoscopy were appropriate based on patient preference to undergo fecal immunochemical testing for CRC screening modality after undergoing colonoscopy with an inadequate bowel preparation. CONCLUSIONS: Veterans underwent inappropriate testing due to failure to undergo serial FIT after a negative result (37.6%), failure to complete colonoscopy following a positive FIT (27.5%), and undergoing inappropriate FIT following a recent colonoscopy (88%). Efforts are still required to improve both patient and provider education and adherence to appropriate fecal immunochemical testing and CRC screening guidelines.
RESUMO
A subset of patients with alcoholic hepatitis present with atypical imaging resembling hepatic tumor infiltration. Our case involves a patient who was initially thought to have multiple large hepatic metastases, ultimately found to have alcoholic hepatitis. It is essential to ask about alcohol use when clinical suspicion is high.
RESUMO
PURPOSE: African Americans (AA) have the highest incidence of colorectal cancer compared with other U.S. populations and more proximal colorectal cancers. The objective is to elucidate the basis of these cancer disparities. EXPERIMENTAL DESIGN: Of note, 566 AA and 328 non-Hispanic White (NHW) colorectal cancers were ascertained in five Chicago hospitals. Clinical and exposure data were collected. Microsatellite instability (MSI) and BRAF (V600E) and KRAS mutations were tested. Statistical significance of categorical variables was tested by the Fisher exact test or logistic regression and age by the Mann-Whitney U test. RESULTS: Over a 10-year period, the median age at diagnosis significantly decreased for both AAs (68-61; P < 0.01) and NHWs (64.5- 62; P = 0.04); more AA patients were diagnosed before age 50 than NHWs (22% vs. 15%; P = 0.01). AAs had more proximal colorectal cancer than NHWs (49.5% vs. 33.7%; P < 0.01), but overall frequencies of MSI, BRAF and KRAS mutations were not different nor were they different by location in the colon. Proximal colorectal cancers often presented with lymphocytic infiltrate (P < 0.01) and were diagnosed at older ages (P = 0.02). Smoking, drinking, and obesity were less common in this group, but results were not statistically significant. CONCLUSIONS: Patients with colorectal cancer have gotten progressively younger. The excess of colorectal cancer in AAs predominantly consists of more proximal, microsatellite stable tumors, commonly presenting lymphocytic infiltrate and less often associated with toxic exposures or a higher BMI. Younger AAs had more distal colorectal cancers than older ones. These data suggest two different mechanisms driving younger age and proximal location of colorectal cancers in AAs.
