OBJECTIVE To evaluate the safety and efficacy of primary repair of colon injuries. MATERIALS AND METHODS A literature review was made of 35 publications containing 5,400 colon injuries in retrospective and prospective studies. RESULTS There were 62 (2.4%) failures in 2,627 primary repairs based on surgeon discretion or absence of risk factors. In(More)
OBJECTIVE Isolated renal artery aneurysms are rare, and controversy remains about indications for surgical repair. Little is known about the impact of endovascular therapy on selection of patients and outcomes of renal artery aneurysms. METHODS We identified all patients undergoing open or endovascular repair of isolated renal artery aneurysms in the(More)
During the 2-year period from January 1, 1987 to December 31, 1988, 656 emergency appendectomies were performed on the Pediatric Surgery Service at the Los Angeles County-USC Medical Center. Of these, 398 patients were 12 years of age or less, and 227 appendices (57%) were perforated or gangrenous. The records of 167 of those patients with perforated or(More)
BACKGROUND To date, reports on outcomes after robotic-assisted pulmonary resection have been confined to small, single-institution case series. Furthermore, no comparison has been made between robotic, open, and video-assisted thoracic surgery (VATS) procedures. We sought to compare the outcomes between these approaches using the State Inpatient Databases(More)
BACKGROUND Fetal and neonatal ovarian cysts are detected frequently by ultrasonography. The presence of these lesions can result in adnexal torsion in utero with autoamputation. Historically, these have been removed at laparotomy. METHODS Retrospective chart review was performed at a single children's hospital from October 1996 to September 2001. (More)
Minimally invasive colon surgery (MIS) has been shown to minimize pain and decrease overall recovery time. No studies have shown a clear oncologic benefit. Some literature suggests that the time to administration of chemotherapy can be important to improve outcomes for advanced colon cancer. The goal of this study is to evaluate the effect of minimally(More)
This study was performed to compare the standard open Swenson pull-through (OSP) with the laparoscopic Swenson pull-through (LSP) for Hirschsprung's disease. The Swenson pull-through was performed on eight patients with a rectosigmoid transition zone, during a 14-month period, using one camera port and three working ports. The results were compared with(More)
The Swenson abdominoperineal pull-through is the authors' preferred treatment for children with Hirschsprung's disease. The present study was performed to determine whether this procedure's principles could be applied to laparoscopic techniques. The operations were performed in 13 mongrel dogs--first to optimize techniques, and second to observe(More)
PURPOSE Patients on total parenteral nutrition (TPN) commonly have hepatobiliary dysfunction. Interruption of the enterohepatic circulation (EHC) and gallbladder stasis are part of the pathogenesis. Cholecystokinin-octapeptide (CCK-OP), by emptying the gallbladder, stimulates the EHC. This study was performed to determine whether daily CCK-OP infusions can(More)
OBJECTIVE Readmission is associated with high mortality, morbidity, and cost. We used the American College of Surgeons National Surgery Quality Improvement Program (ACS-NSQIP) to determine risk factors for readmission after lower extremity bypass (LEB). METHODS We identified all patients who received LEB in the 2011 ACS-NSQIP database. Multivariable(More)
