Gastroenterology visitation and reminders predict surveillance uptake for patients with adenomas with high-risk features.

Individuals diagnosed with colorectal adenomas with high-risk features during screening colonoscopy have increased risk for the development of subsequent adenomas and colorectal cancer. While US guidelines recommend surveillance colonoscopy at 3 years in this high-risk population, surveillance uptake is suboptimal. To inform future interventions to improve surveillance uptake, we sought to assess surveillance rates and identify facilitators of uptake in a large integrated health system. We utilized a cohort of patients with a diagnosis of ≥ 1 tubular adenoma (TA) with high-risk features (TA ≥ 1 cm, TA with villous features, TA with high-grade dysplasia, or ≥ 3 TA of any size) on colonoscopy between 2013 and 2016. Surveillance colonoscopy completion within 3.5 years of diagnosis of an adenoma with high-risk features was our primary outcome. We evaluated surveillance uptake over time and utilized logistic regression to detect factors associated with completion of surveillance colonoscopy. The final cohort was comprised of 405 patients. 172 (42.5%) patients successfully completed surveillance colonoscopy by 3.5 years. Use of a patient reminder (telephone, electronic message, or letter) for due surveillance (adjusted odds = 1.9; 95%CI = 1.2-2.8) and having ≥ 1 gastroenterology (GI) visit after diagnosis of an adenoma with high-risk features (adjusted odds = 2.6; 95%CI = 1.6-4.2) significantly predicted surveillance colonoscopy completion at 3.5 years. For patients diagnosed with adenomas with high-risk features, surveillance colonoscopy uptake is suboptimal and frequently occurs after the 3-year surveillance recommendation. Patient reminders and visitation with GI after index colonoscopy are associated with timely surveillance completion. Our findings highlight potential health system interventions to increase timely surveillance uptake for patients diagnosed with adenomas with high-risk features.

Early Aggressive Hydration Hastens Clinical Improvement in Mild Acute Pancreatitis.

OBJECTIVES: Early aggressive intravenous hydration is recommended for acute pancreatitis treatment although randomized trials have not documented benefit. We performed a randomized trial of aggressive vs. standard hydration in the initial management of mild acute pancreatitis. METHODS: Sixty patients with acute pancreatitis without systemic inflammatory response syndrome (SIRS) or organ failure were randomized within 4 h of diagnosis to aggressive (20 ml/kg bolus followed by 3 ml/kg/h) vs. standard (10 ml/kg bolus followed by 1.5 mg/kg/h) hydration with Lactated Ringer's solution. Patients were assessed at 12-h intervals. At each interval, in both groups, if hematocrit, blood urea nitrogen (BUN), or creatinine was increased, a bolus of 20 ml/kg followed by 3 ml/kg/h was given; if labs were decreased and epigastric pain was decreased (measured on 0-10 visual analog scale), hydration was then given at 1.5 ml/kg/h and clear liquid diet was started. The primary endpoint, clinical improvement within 36 h, was defined as the combination of decreased hematocrit, BUN, and creatinine; improved pain; and tolerance of oral diet. RESULTS: The mean age of the patients was 45 years and only 14 (23%) had comorbidities. A higher proportion of patients treated with aggressive vs. standard hydration showed clinical improvement at 36 h: 70 vs. 42% (P=0.03). The rate of clinical improvement was greater with aggressive vs. standard hydration by Cox regression analysis: adjusted hazard ratio=2.32, 95% confidence interval 1.21-4.45. Persistent SIRS occurred less commonly with aggressive hydration (7.4 vs. 21.1%; adjusted odds ratio (OR)=0.12, 0.02-0.94) as did hemoconcentration (11.1 vs. 36.4%, adjusted OR=0.08, 0.01-0.49). No patients developed signs of volume overload. CONCLUSIONS: Early aggressive intravenous hydration with Lactated Ringer's solution hastens clinical improvement in patients with mild acute pancreatitis.

Multiple Preoperative Endoscopic Retrograde Cholangiopancreatography and Large Common Bile Duct Diameter Predict the Need for Complex Surgery.

Endoscopic retrograde cholangiopancreatography (ERCP) is frequently used to clear the common bile duct (CBD) in patients with choledocholithiasis. While a single ERCP is usually effective, many patients undergo multiple ERCP attempts before cholecystectomy. Here we sought to identify preoperative factors predictive of surgical complexity beyond routine laparoscopic cholecystectomy after ERCP. Data were prospectively collected for all ERCPs between September 2010 and February 2012 at a public academic medical center including demographics, indication, stone presence, CBD diameter, sphincterotomy, stent placement, and ERCP number. A total of 124 ERCPs were attempted in 73 patients with choledocholithiasis, 10 per cent of whom presented with cholangitis. Fifty-six per cent of patients underwent one ERCP, whereas 16 per cent required ≥ 3 procedures. Laparoscopic cholecystectomy was performed in 58 (79%) patients whereas 15 (21%) patients required more complex operations including eight open CBD explorations and two hepaticojejunostomies. The likelihood of requiring more complex surgery correlated with increasing number of ERCPs with an adjusted odds ratio of 5.75 (95% confidence interval: 2.31-14.3, P ≤ 0.001). Increased CBD diameter also correlated with complex surgery with adjusted odds ratio of 1.5 (95% confidence interval: 1.10-2.06, P = 0.012) for each millimeter. The number of preoperative ERCPs and CBD diameter in choledocholithiasis patients are strong predictors of the need for open surgery and CBD exploration and should be considered in surgical planning and consent for patients requiring more than one ERCP procedure.
