Outcomes in the management of appendicitis and cholecystitis in the setting of a new acute care surgery service model: impact on timing and cost.

Background: The acute care surgery model is a novel notion in the provision of emergency general surgery. To date, several studies have analyzed the effects on patient health outcomes and timeliness of care for nontrauma patients within the scope of acute general surgery and emergencies, but none have assessed the cost benefits of this model.

Study Design: A retrospective analysis of patients undergoing appendectomy or cholecystectomy in the setting of acute abdomen was performed to compare data from 2 cohorts, the traditional model from July 2009 to June 2010 and the acute care surgery model from July 2010 to June 2011.

Tumor size and presence of calcifications on ultrasonography are pre-operative predictors of lymph node metastases in patients with papillary thyroid cancer.

Background And Objectives: Lymph node metastases in papillary thyroid cancer (PTC) are common and their presence can significantly alter the treatment for patients with PTC. We therefore sought to identify pre-operative predictors of lymph node metastases in patients with PTC.

Methods: A thyroid tumor database was queried to identify patients with a pre-operative diagnosis of PTC and underwent thyroidectomy between January 2006 and August 2009.

A prospective analysis of critical limb ischemia: factors leading to major primary amputation versus revascularization.

In our aging population, primary major amputations (AMP, below-knee or above-knee) continue to be performed despite advances in revascularization. We hypothesized that not only patient comorbidities but also the system of health-care delivery affected the treatment of patients with critical limb ischemia (CLI). A prospective analysis of patients presenting with CLI was undertaken to determine whether patient-specific factors or healthcare delivery factors (system-related) influenced treatment with primary AMP versus lower extremity revascularization (LER).
