Robotic surgical devices have developed beyond the investigational stage and currently are routinely used in minimally invasive general surgery, pediatric surgery, gynecology, urology, cardiothoracic surgery, and otorhinolaryngology. Robotic devices continue to evolve. As they become less expensive and more widely disseminated, these devices likely will(More)
BACKGROUND Indications for and results of laparoscopic adjustable gastric banding (LAGB) and laparoscopic gastric bypass (LGB) are still controversial, especially between Europe and the United States. The recent availability of gastric bandings in the United States made it necessary to compare the two techniques. STUDY DESIGN We compared a series of 456(More)
Recently we have shown that laparoscopic Toupet fundoplication is associated with a high degree of late failure when employed as a primary treatment for gastroesophageal reflux disease (GERD). This study defines preoperative risk factors that predispose patients to failure. Data from 48 patients with objective follow-up performed as part of a prospective(More)
BACKGROUND AND OBJECTIVES Mesh fixation in laparoscopic ventral hernia repair typically involves the use of tacks, transabdominal permanent sutures, or both of these. We compared postoperative pain after repair with either of these 2 methods. METHODS Patients undergoing laparoscopic ventral hernia repair at the Mount Sinai Medical Center were(More)
The aim of this study was to describe the occurrence and clinical characteristics of symptomatic internal hernias (IH) after laparoscopic bariatric procedures. We conducted a retrospective review of cases of IH after 1,064 laparoscopic gastric bypasses (LGB) and biliopancreatic diversions with duodenal switch (LBPD-DS) performed from September 1998 to(More)
We describe an in vivo method for the quantitative analysis of human necrotical anatomy. The technique allows unfolded regions of functional and morphological interest to be measured planimetrically. Two-dimensional cortical maps and surface area determinations derived from magnetic resonance images of monozygotic twins are presented. In addition,(More)
HYPOTHESIS Based on retrospective, uncontrolled studies, it has been claimed that Nissen fundoplication should be performed over an esophageal bougie to minimize postoperative dysphagia. We hypothesized that a surgeon experienced in laparoscopic fundoplication will have similar rates of postoperative dysphagia whether or not an esophageal bougie is used. (More)
BACKGROUND 10 to 25% of patients undergoing bariatric surgery will require a revision, either for unsatisfactory weight loss or for complications. Reoperation is associated with a higher morbidity and has traditionally been done in open fashion. The purpose of this study was to determine the safety and efficacy of reoperative surgery using a laparoscopic(More)
Biliopancreatic diversion with duodenal switch (BPD-DS) is a well-known emerging open procedure that appears to be as effective as other bariatric operations and has been shown to provide excellent long-term weight loss. Therefore we looked at the safety and efficacy of the laparoscopic BPD-DS procedure compared to open BPD-DS in superobese patients (body(More)
Background: Stereoscopic (3-D) monitors and head-mounted displays have promised to facilitate laparoscopic surgery by increasing positional accuracy and decreasing operative time. To test this hypothesis, we evaluated the performance of subjects using these displays to perform standardized laparoscopic dexterity drills. Methods: Fifty laparoscopic novices(More)
