OBJECTIVES Many studies have shown laparoscopic distal pancreatectomy (LDP) to have benefits over open distal pancreatectomy (ODP). This institution made a unique abrupt transition from an exclusively open approach to a preference for the laparoscopic technique. This study aimed to compare outcomes in patients undergoing LDP and ODP, respectively, over the(More)
Despite the standardization of laparoscopic cholecystectomy (LC), the rate of bile duct injury (BDI) has risen from 0.2 to 0.5 %. Routine use of intraoperative cholangiography (IOC) has not been widely accepted because of its cost and a lack of evidence concerning its use in preventing BDI. Fluorescent cholangiography (FC), which has recently been advocated(More)
AIM To investigate national trends in distal pancreatectomy (DP) through query of three national patient care databases. METHODS From the Nationwide Inpatient Sample (NIS, 2003-2009), the National Surgical Quality Improvement Project (NSQIP, 2005-2010), and the Surveillance Epidemiology and End Results (SEER, 2003-2009) databases using appropriate(More)
Pulmonary embolism (PE) after venous procedures is fortunately rare. Our goal was to analyze the data of patients who developed PE after endovenous thermal ablation and phlebectomy for varicose veins and to review the literature on this subject. We report on three patients who developed PE after radiofrequency ablation of the great saphenous vein and mini(More)
Distal pancreatectomy is the therapeutic option of choice for patients with a benign or malignant lesion located in the body and/or tail of the pancreas when surgical intervention is indicated. With recent advances in and wide spread use of imaging studies, lesions of the pancreas are being diagnosed more commonly and it is likely that this will translate(More)
The small volume of the infant abdomen limits the application of laparoscopic procedures. We successfully repaired a duodenal atresia in a 2-kg female infant using a standard diamond-shaped anastomosis and intracorporeal suturing and knot-tying techniques. Anesthesia and positive pressure ventilation assured adequate gas exchange during pneumoperitoneum(More)
BACKGROUND Variable results regarding general surgery residency program (GSRP) impact on patient outcomes and charges are reported. The aim of this study was to determine any significant differences in patient outcomes and cost with a new GSRP. METHODS We analyzed all laparoscopic appendectomies (lap-ap), cholecystectomies (lap-chole), and inguinal hernia(More)
Weight gain or loss is determined by the difference between calorie intake and energy expenditure. The Mifflin metabolic equation most accurately predicts resting energy expenditure (REE) in morbidly obese patients. Hypometabolizers have a measured REE that is much less than predicted and pose the greatest challenge for weight loss induced by restriction of(More)
INTRODUCTION Modifications to conventional laparoscopic cholecystectomy are aimed to decrease abdominal pain and improve cosmetic results. Single-port robotic cholecystectomy is a safe and feasible approach that has been reported in adults, though reports are limited in children. This study aims to report our experience with single-port robotic(More)
