Predictive Factors of Mortality From Nonvariceal Upper Gastrointestinal Hemorrhage: A Multicenter Study

OBJECTIVES:From an Italian Registry of patients with upper gastrointestinal hemorrhage (UGIH), we assessed the clinical outcomes and explored the roles of clinical, endoscopic, and therapeutic factors on 30-day mortality in a real life setting.METHODS:Prospective analysis of consecutive patients endoscoped for UGIH at 23 community and tertiary care institutions from 2003 to 2004. Covariates and outcomes were defined a priori and 30-day follow-up obtained. Logistic regression analysis identified predictors of mortality.RESULTS:One thousand and twenty patients were included. A total of 46 patients died for an overall 4.5% mortality rate. In all, 85% of deaths were associated with one or more major comorbidity. Sixteen of 46 patients (35%) died within the first 24 h of the onset of bleeding. Of these, eight had been categorized as ASA class 1 or 2 and none of them was operated upon, despite a failure of endoscopic intention to treatment in four. Regression analysis showed advanced age, presence of severe comorbidity, low hemoglobin levels at presentation, and worsening health status as the only independent predictors of 30-day mortality (P < 0.001). The acute use of a PPI exerted a protective effect (OR 0.23, 95% CI 0.09–0.73). Recurrent bleeding was low (3.2%). Rebleeders accounted for only 11% of the total patients deceased (OR 3.27, 95% CI 1.5–11.2).CONCLUSIONS:These results indicate that 30-day mortality for nonvariceal bleeding is low. Deaths occurred predominantly in elderly patients with severe comorbidities or those with failure of endoscopic intention to treatment.

Predicting Mortality in Non-Variceal Upper Gastrointestinal Bleeders: Validation of the Italian PNED Score and Prospective Comparison With the Rockall Score

OBJECTIVES:We sought (i) to validate a new prediction rule of mortality (Progetto Nazionale Emorragia Digestiva (PNED) score) on an independent population with non-variceal upper gastrointestinal bleeding (UGIB) and (ii) to compare the accuracy of the Italian PNED score vs. the Rockall score in predicting the risk of death.METHODS:We conducted prospective validation of analysis of consecutive patients with UGIB at 21 hospitals from 2007 to 2008. Outcome measure was 30-day mortality. All the variables used to calculate the Rockall score as well as those identified in the Italian predictive model were considered. Calibration of the model was tested using the χ2 goodness-of-fit and performance characteristics with receiver operating characteristic (ROC) analysis. The area under the ROC curve (AUC) was used to quantify the diagnostic accuracy of the two predictive models.RESULTS:Over a 16-month period, data on 1,360 patients were entered in a national database and analyzed. Peptic ulcer bleeding was recorded in 60.7% of cases. One or more comorbidities were present in 66% of patients. Endoscopic treatment was delivered in all high-risk patients followed by high-dose intravenous proton pump inhibitor in 95% of them. Sixty-six patients died (mortality 4.85%; 3.54–5.75). The PNED score showed a high discriminant capability and was significantly superior to the Rockall score in predicting the risk of death (AUC 0.81 (0.72–0.90) vs. 0.66 (0.60–0.72), P<0.000). Positive likelihood ratio for mortality in patients with a PNED risk score >8 was 16.05.CONCLUSIONS:The Italian 10-point score for the prediction of death was successfully validated in this independent population of patients with non-variceal gastrointestinal bleeding. The PNED score is accurate and superior to the Rockall score. Further external validation at the international level is needed.

Long-term efficacy of vacuum-assisted therapy (Endo-SPONGE®) in large anastomotic leakages following anterior rectal resection

Background: The aim of our study was to test the long-term efficacy of Endo-SPONGE® therapy in a group of patients treated in our center with vacuum-assisted therapy because of anastomotic leakages after colorectal surgery. Methods: Eleven patients [male: 6; mean age: 71 (range: 44-82) years] who had anastomotic leakage treated with Endo-SPONGE® placement were included in the study. Patient records were examined retrospectively. All patients with documented anastomotic leakage on abdominal computed tomography following an anterior resection of the rectum for rectal cancer underwent sigmoidoscopy to determine the extent of the anastomotic defect and the size of the presacral abscess. Results: Ten of the 11 patients (90.9%) showed closure of the anastomotic leakage after a mean of 16 sponge changes. During follow up [mean: 29 (range: 6-64) months], we observed two cases of anastomotic stricture. Treatment failure was observed in one patient who presented an increased size of dehiscence after 23 sessions of endoscopic treatment, despite an initial good response. Conclusions: Our study substantially confirms previous conclusions and reaffirms that Endo-SPONGE® treatment for colorectal anastomotic leakages, performed in suitable patients, represents a successful and safe approach. The reduction in wound closure time, mild-to-moderate discomfort and possibly shorter hospitalization suggest that Endo-SPONGE® treatment can be a prominent therapeutic regimen with adequate patient acceptance.

Esophagitis dissecans is most often idiopathic, but it can be associated with use of nonsteroidal anti-inflammatory drugs or bisphosphonates, consumption of hot beverages, celiac disease, or autoimmune bullous dermatoses (2). Histological features include the following: parakeratosis, intraepithelial splitting at varying degrees above the basal layer, occasional association with intraepithelial bullae and minimal or no inflammatory component, and unusually long, detached fragments of superficial epithelium (3).
