Emergent surgical management of malignant large bowel obstruction (LBO) carries a high rate of morbidity and mortality. Self-expanding metal stents have emerged as an alternative for palliation of malignant LBO. However, there are few long-term studies documenting the effect of surgical palliation or colonic stents on symptoms or quality of life (QoL). ⋯ Both stent placement and surgical diversion provide durable improvement in symptoms from LBO, as readily assessed by the Colon Obstruction Score. QoL is difficult to assess in terminal cancer patients, but colon stent placement is associated with improved overall QoL and QoL related to gastrointestinal symptoms.

This article outlines our current perioperative management of patients undergoing cystectomy and urinary diversion using advancements in perioperative care to allow for early institution of an oral diet and early hospital discharge. ⋯ Successful application of a fast track program has been applied to our patients undergoing radical cystectomy and urinary diversion, with the potential to use evidence-based modifications to reduce morbidity and improve recovery.

Management of severe traumatic lower extremity injuries remains a considerable challenge. Free tissue transfer is now a standard part of reconstruction for Gustilo IIIB and IIIC injuries. There is limited information on arterial injury patterns in this population. We undertook a review of our experience to gain insight on vascular injury patterns and surgical outcomes. ⋯ Angiography of severe lower extremity injuries requiring free flap reconstruction usually revealed arterial injury and is generally indicated. In our experience, the anterior tibial artery is most commonly injured and the posterior tibial artery is most likely to be spared and used as a recipient.

Comparative Study
Risk adjustment in the American College of Surgeons National Surgical Quality Improvement Program: a comparison of logistic versus hierarchical modeling.
Although logistic regression has commonly been used to adjust for risk differences in patient and case mix to permit quality comparisons across hospitals, hierarchical modeling has been advocated as the preferred methodology, because it accounts for clustering of patients within hospitals. It is unclear whether hierarchical models would yield important differences in quality assessments compared with logistic models when applied to American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) data. Our objective was to evaluate differences in logistic versus hierarchical modeling for identifying hospitals with outlying outcomes in the ACS-NSQIP. ⋯ When applied to ACS-NSQIP data, logistic and hierarchical models provided nearly identical results with respect to identification of hospitals' observed-to-expected events ratio outliers. As hierarchical models are prone to implementation problems, logistic regression will remain an accurate and efficient method for performing risk adjustment of hospital quality comparisons.
