OBJECTIVE To determine rates and mechanisms of failure in 857 consecutive patients undergoing laparoscopic fundoplication for gastroesophageal reflux disease or paraesophageal hernia (1991-1998), and compare this population with 100 consecutive patients undergoing fundoplication revision (laparoscopic and open) at the authors' institution during the same(More)
SUMMARY BACKGROUND DATA To inform surgeons about the practical issues to be considered for successful integration of virtual reality simulation into a surgical training program. The learning and practice of minimally invasive surgery (MIS) makes unique demands on surgical training programs. A decade ago Satava proposed virtual reality (VR) surgical(More)
Primary laparoscopic hiatal hernia repair is associated with up to a 42% recurrence rate. This has lead to the use of mesh for crural repair, which has resulted in an improved recurrence rate (0–24%). However, mesh complications have been observed. We compiled two cases, and our senior author contacted other experienced esophageal surgeons who provided 26(More)
BACKGROUND Virtual reality (VR) training has been shown previously to improve intraoperative performance during part of a laparoscopic cholecystectomy. The aim of this study was to assess the effect of proficiency-based VR training on the outcome of the first 10 entire cholecystectomies performed by novices. METHODS Thirteen laparoscopically inexperienced(More)
A small but significant percentage of patients are considered failures after laparoscopic Nissen fundoplication (LNF). We sought to identify preoperative predictors of failure in a cohort of patients who underwent LNF more than 10 years ago. Of 312 consecutive patients undergoing primary LNF between 1992 and 1995, recent follow-up was obtained from 166(More)
BACKGROUND Previous randomized studies of laparoscopic appendectomy produced conflicting recommendations, and the adequacy of sample sizes is generally unknown. We compared clinical and economic outcomes after laparoscopic and open appendectomy in a sample of predetermined statistical power. METHODS A pre-study power analysis suggested that 200 randomized(More)
BACKGROUND AND OBJECTIVES Diarrhea-associated hemolytic uremic syndrome (D+HUS) is a common cause of acute kidney injury in children. Mutations in alternative pathway (AP) complement regulatory proteins have been identified in severe cases of thrombotic microangiopathy, but the role of the AP in D+HUS has not been studied. Therefore, we determined whether(More)
Background: Laparoscopic fundoplication has become the standard for operative treatment of gastroesophageal reflux disease (GERD). Methods: We reviewed our experience with 1,000 consecutive patients receiving laparoscopic fundoplication for GERD (n = 882) or paraesophageal hernia (n = 118) between October 1991 and July 1999. Patients with achalasia and(More)
OBJECTIVE The largest series in the literature dealing with redo fundoplication was presented and published in 1999 and included 100 patients. Herein we update this initial series of 100, with 207 additional patients who have undergone redo fundoplication (n = 307). SUMMARY BACKGROUND DATA Increasing numbers of patients are failing esophagogastric(More)
