RESUMEN
BACKGROUND AND AIM: Upper gastrointestinal bleeding (UGIB) has a high mortality rate and requires efficient and directed acute management. This project aimed to assess patient outcomes following changes to UGIB management protocols at Northern Hospital, Victoria, Australia. Changes involved streamlining management under a single inpatient unit, earlier endoscopy, blood transfusion thresholds, and risk stratification. METHODS: This was a cohort study of 400 patients aged ≥18 years admitted to Northern Hospital who underwent endoscopy for acute UGIB. Data of preprotocol changes (Group 1) and prospectively postprotocol changes (Group 2) were collected retrospectively. Primary outcomes were inpatient mortality, rebleeding, radiologic or surgical intervention, and endoscopic reintervention. Secondary outcomes included length of stay (LOS) ≥4 days and blood units transfused. Univariate analyses were conducted comparing groups and associations between variables and outcomes, followed by multivariate analyses for each outcome. RESULTS: There was no difference in mortality on multivariate analysis (P = 0.95). Rebleeding reduced by 4% (adjusted odds ratio [AOR] 0.48; P = 0.03), LOS ≥4 days reduced by 15.1% (AOR 0.46; P < 0.00) and median blood units transfused decreased with adjusted incidence rate ratio of 0.81 (P = 0.00). Early endoscopy (i.e. ≤12 h) for all patients increased by 15% (P < 0.00) and there were 12% more high-risk patients (i.e. Glasgow-Blatchford score ≥ 12) in Group 2 (P = 0.01). CONCLUSION: Following changes to UGIB protocols at this Australian hospital, endoscopic times decreased with reductions in rebleeding, LOS ≥4 days, and blood transfusion rates. These findings demonstrate improved outcomes after the implementation of new treatment targets focusing on streamlined care of patients presenting with UGIB.
RESUMEN
BACKGROUND AND AIM: Dietary restrictions contribute to the unpleasantness of bowel preparation for colonoscopy. We compare the effectiveness and tolerability of a low residue diet of white-colored foods ("White Diet") with a clear-fluid diet the day prior to colonoscopy in an endoscopist-blinded randomized non-inferiority trial. METHODS: Adults undergoing outpatient colonoscopy were randomized with stratification by procedure timing to a White Diet or clear-fluid diet. All received a 2-L polyethylene glycol lavage solution with ascorbate, sodium sulfate, and electrolytes, the day-before for morning and as a split-dose for afternoon procedures. The primary end-point was successful bowel preparation (A or B on the Harefield Cleansing Scale). Regimen tolerance/acceptance was assessed by questionnaire. An intention-to-treat analysis with a predefined non-inferiority margin of 15% was used to compare efficacy. RESULTS: A total of 226 patients (average age 52 years, 51% male) were randomized (111 clear diet, 115 White Diet). Bowel preparation was successful in 91% on the clear-fluid diet vs 84.4% on the White Diet, difference being -6.6% (lower one sided 95% CI -13.8%), with no difference according to diet. The split-dose regimen (in 55%) had a higher success rate than day-before regimen (96% vs 80%, p < 0.001). The White Diet was preferred with less hunger and interference with daily activities (p < 0.001). Procedural/withdrawal time and polyp/adenoma detection were similar between groups. CONCLUSIONS: The White Diet was preferred and better tolerated by patients without detriment to the success of bowel preparation or colonoscopy performance, especially with the split-dose regimen.

Increasing interest in identifying an effective strategy for decreasing the burden of esophageal adenocarcinoma (EAC) has been fuelled by the rising EAC rates worldwide, the morbidity associated with esophagectomy, and the development of endoscopic methods for curing early-stage EAC. In the face of this enthusiasm, however, we should be cautious about continuing our current evidence-free approach to screening and one with unclear benefits and unclear costs to the community. The literature is increasingly recognizing that the value of traditional endoscopy for screening and surveillance of Barrett esophagus may be more limited than initially believed. A better understanding of the risk factors for Barrett esophagus and progression to dysplasia and a more individualized risk calculation will be useful in defining populations to consider for Barrett screening. The development of novel, nonendoscopic screening techniques and of less expensive endoscopic techniques holds promise for a cost-effective screening and surveillance method to curtail the increasing rates of EAC.
RESUMEN
BACKGROUND & AIMS: Bleeding is the main complication of wide-field endoscopic mucosal resection (WF-EMR) for large colonic lesions. Few studies have examined bleeding outcomes after WF-EMR, and there are no evidence-based guidelines for management of bleeding in this group. We analyzed outcomes of patients with clinically significant post-EMR bleeding (CSPEB) and present a management algorithm based on our findings. METHODS: In a prospective study, we collected data from WF-EMR of sessile colorectal polyps 20 mm or larger from 1039 patients who participated in the Australian Colonic Endoscopic resection multicenter study from July 2008 through May 2012. Data included patient and lesion characteristics and procedural, clinical, and histologic outcomes. Patients participated in a structured telephone interview 14 days after the procedure; independent predictors of a moderate or severe outcome by American Society of Gastrointestinal Endoscopists criteria, or any intervention for hemostasis, were identified. RESULTS: Sixty-two patients had CSPEB (6.0%); 34 were managed conservatively (55%) and 27 underwent colonoscopy (44%). One patient had primary embolization. Endoscopic therapy was applied in 21 cases; 14 had active bleeding. Two of the conservatively managed cases underwent colonoscopy for rebleeding after discharge. On multivariable analysis, moderate or severe bleeding events were associated with hemodynamic instability (odds ratio, 12.3; P = .046) and low level of hemoglobin at presentation (odds ratio, 0.50 per 1.0 g/dL; P = .005). Intervention for hemostasis was associated with hourly or more frequent hematochezia (odds ratio, 36.7; P = .001), American Society of Anesthesiologists grade 2 or higher (odds ratio, 20.1; P < .001), and transfusion (odds ratio, 18.7; P = .003). CONCLUSIONS: Based on a multicenter prospective study, CSPEB resolves spontaneously in 55% of patients. We developed a risk factor-based algorithm that might assist physicians in the management of bleeding. Patients responding to initial resuscitation can be observed, with a lower threshold for intervention in those with the identified risk factors.
