RESUMO
BACKGROUND: Surgery remains the dominant treatment for large-bowel obstruction, with emerging data on self-expanding metallic stents. OBJECTIVE: The aim of this study was to assess whether stent insertion improves quality of life and survival in comparison with surgical decompression. DESIGN: This study reports on a randomized control trial (registry number ACTRN012606000199516). SETTING: This study was conducted at Royal Prince Alfred Hospital, Sydney, and Western Hospital, Melbourne. PATIENTS AND INTERVENTION: Patients with malignant incurable large-bowel obstruction were randomly assigned to surgical decompression or stent insertion. MAIN OUTCOME MEASURES: The primary end point was differences in EuroQOL EQ-5D quality of life. Secondary end points included overall survival, 30-day mortality, stoma rates, postoperative recovery, complications, and readmissions. RESULTS: Fifty-two patients of 58 needed to reach the calculated sample size were evaluated. Stent insertion was successful in 19 of 26 (73%) patients. The remaining 7 patients required a stoma compared with 24 of 26 (92%) surgery group patients (p < 0.001). There were no stent-related perforations or deaths. The surgery group had significantly reduced quality of life compared with the stent group from baseline to 1 and 2 weeks (p = 0.001 and p = 0.012), and from baseline to 12 months (p = 0.01) in favor of the stent group, whereas both reported reduced quality of life. The stent group had an 8% 30-day mortality compared with 15% for the surgery group (p = 0.668). Median survival was 5.2 and 5.5 months for the groups (p = 0.613). The stent group had significantly reduced procedure time (p = 0.014), postprocedure stay (p = 0.027), days nothing by mouth (p = 0.002), and days before free access to solids (p = 0.022). LIMITATIONS: This study was limited by the lack of an EQ-5D Australian-based population set. CONCLUSIONS: Stent use in patients with incurable large-bowel obstruction has a number of advantages with faster return to diet, decreased stoma rates, reduced postprocedure stay, and some quality-of-life benefits.

INTRODUCTION: The aim of this study was to derive and internally validate a prediction rule for short stay admissions (SSAs) in trauma patients admitted to a major trauma centre. METHODS: A retrospective study of all trauma activation patients requiring inpatient admission at a single inner city major trauma centre in Australia between 2007 and 2011 was conducted. Logistic regression was used to derive a multivariable model for the outcome of SSA (length of stay ≤2 days excluding deaths or intensive care unit admission). Model discrimination was tested using area under receiver operator characteristic curve analyses and calibration was tested using the Hosmer-Lemeshow test statistic. Validation was performed by splitting the dataset into derivation and validation datasets and further tested using bootstrap cross validation. RESULTS: A total of 2593 patients were studied and 30% were classified as SSAs. Important independent predictors of SSA were injury severity score ≤8 (OR 7.8; 95% CI 5.0 to 11.9), Glasgow coma score 14-15 (OR 3.2; 95% CI 1.8 to 5.4), no need for operative intervention (OR 2.2; 95% CI 1.6 to 3.2) and age < 65 years. (OR 1.7; 95% CI 1.2 to 2.6). The overall model had an area under receiver operator characteristic curve of 0.84 (95% CI 0.82 to 0.87) for the derivation dataset. After bootstrap cross validation the area under the curve of the final model was 0.83 (95% CI 0.81 to 0.84). CONCLUSIONS: We report a prediction rule that could be used to establish admission criteria for a trauma short stay unit. Further studies are required to prospectively validate the prediction rule.
