BACKGROUND The surgical management of acute complicated diverticulitis has evolved to avoid emergency surgery in favor of elective resection. The optimal manner to accomplish this goal remains debatable. OBJECTIVE The purpose of this study was to examine the efficacy of nonoperative management of acute diverticulitis with abscess or perforation. DESIGN(More)
BACKGROUND Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the treatment of choice for patients with ulcerative colitis and familial adenomatous. This study examined the impact of the surgical approach (laparoscopic versus open) to IPAA on short-term outcomes and time to ileostomy closure in 2-stage restorative proctocolectomies. (More)
The significance of lateral pelvic lymph nodes (LPLN) in rectal cancer remains unclear. The purpose of this study was to determine the outcome of patients with LPLNs identified on pretherapy imaging who were treated with neoadjuvant therapy followed by proctectomy without LPLN dissection. Pretherapy imaging of patients with stage III rectal cancer was(More)
Lung transplantation is the treatment of choice for end-stage pulmonary diseases. A limited donor supply has resulted in 4,000 patients on the waiting list. Currently, 10-20% of donor organs offered for transplantation are deemed suitable under the selection criteria, of which 15-25% fail due to primary graft dysfunction (PGD). This has spawned efforts to(More)
BACKGROUND Patients requiring an ileostomy following colorectal surgery are at risk for increased health-care utilization after discharge. Prior studies evaluating postoperative ileostomy care may underestimate health-care utilization by reporting only "same-institution" readmission rates. OBJECTIVE The aim of this study was to determine the rates of(More)
OBJECTIVES Ischemia-reperfusion injury after lung transplantation is associated with significant morbidity and mortality. The activation of the transcription factor nuclear factor kappaB is central to the 2 important pathways that characterize ischemia-reperfusion injury, namely the inflammatory response and apoptosis. The purpose of this study was to(More)
Lung transplantation is the only viable treatment option that can improve survival and enhance the quality of life of patients with end-stage lung diseases such as emphysema, cystic fibrosis, idiopathic pulmonary fibrosis, and primary pulmonary hypertension. However, the long-term survival of lung allografts is still limited by the development of(More)
Experimental gene therapy is a promising strategy to prevent ischemia-reperfusion (I/R) injury and allograft rejection after lung transplantation, and methods will eventually be needed to characterize pulmonary transgene expression in vivo in humans. Therefore, we studied positron emission tomography (PET) as a means of performing in vivo molecular imaging(More)
BACKGROUND AND OBJECTIVES Guidelines on the management of colon cancer state that extensive colectomy should be "considered" for patients of young age (<50). This study aimed to compare the risk of metachronous cancer, overall recurrence and mortality between segmental and extended colon resections in patients under the age of 50 with sporadic CRC. (More)
HuR is a ubiquitous nucleocytoplasmic RNA-binding protein that exerts pleiotropic effects on cell growth and tumorigenesis. In this study, we explored the impact of conditional, tissue-specific genetic deletion of HuR on intestinal growth and tumorigenesis in mice. Mice lacking intestinal expression of HuR (Hur (IKO) mice) displayed reduced levels of cell(More)
