Background: Radiofrequency ablation (RFA) is increasingly used for the local destruction of unresectable hepatic malignancies. There is little information on its optimal approach or potential complications. Methods: Since late 1997, we have undertaken 91 RFA procedures to ablate 231 unresectable primary or metastatic liver tumors in 84 patients. RFA was(More)
BACKGROUND The American College of Surgeons Oncology Group Z0011 trial has been lauded as practice changing. We sought to identify its impact on breast cancer surgery in the community hospital setting. METHODS A retrospective review was performed from 8 community hospitals identifying patients with invasive breast cancer meeting the Z0011 criteria. The(More)
BACKGROUND Most cytoreduction with hyperthermic intraperitoneal chemotherapy procedures are performed at academic tertiary referral centers with numerous surgical oncology faculty. The objective of this study was to review the postoperative morbidity and mortality data of our institution, a large community hospital. METHODS This was a retrospective cohort(More)
BACKGROUND Recent studies have shown a direct correlation between C-reactive protein (CRP) level and obesity. There has also been increasing evidence that elevated CRP level is a significant risk factor for cardiac events and stroke. We wanted to evaluate whether CRP is altered by gastric bypass surgery. In addition, we wanted to investigate whether there(More)
BACKGROUND The rate of recurrent appendicitis is low following nonoperative management of complicated appendicitis. However, recent data suggest an increased rate of neoplasms in these cases. METHODS The study was a retrospective review of patients with acute appendicitis at 2 university-affiliated community hospitals over a 12-year period. The primary(More)
BACKGROUND Distant metastases from colon cancer spread most frequently to the liver and the lung. Risk factors include positive lymph nodes and high grade tumors. Isolated metastases to the appendicular skeleton are very rare, particularly in the absence of identifiable risk factors. CASE REPORT The patient was a 55 year old male with no previous personal(More)
Background: Sentinel lymph node dissection (SLND) for small, early-stage breast cancer is well accepted. However, the role of SLND for large primary breast cancer is controversial. We investigated the feasibility and clinical applicability of SLND in patients with large (≥5 cm) breast cancers and clinically negative axillae. Methods: A prospectively entered(More)
Paraduodenal hernias are the most common forms of intraabdominal hernias, accounting for 53% of all internal hernias. However, these account for only 0.2% to 0.9% of all small intestinal obstructions overall. Patients usually report vague abdominal pains and discomfort lasting for many years. Furthermore, in-patient diagnosis and management can last up to(More)
Lymphatic mapping/sentinel lymphadenectomy (LM/SL) has become a routine part of our treatment algorithm for primary melanoma, yet its role in the management of thick (≥4-mm) lesions is unknown. One hundred twenty-one patients with thick primaries underwent LM/SL at our institute. Survival curves were constructed from Kaplan-Meier estimates and analyzed by(More)
BACKGROUND Radiofrequency ablation (RFA) of hepatic malignancies has been performed successfully via a percutaneous route or at laparotomy. We analyzed the efficacy and utility of laparoscopic intraoperative ultrasound and RFA in patients with unresectable hepatic malignancies. METHODS Between November 1997 and November 1999, 27 patients with unresectable(More)
