BACKGROUND We report our short-term experience with peroral endoscopic myotomy (POEM) and compare perioperative outcomes with laparoscopic Heller myotomy (LHM) for achalasia. METHODS Patients from an institutional review board-approved protocol underwent POEM and were followed prospectively. Comparisons were made, in a prospective esophageal database,(More)
The advent of laparoscopic ventral hernia repair (LVHR) not only reduced the morbidity associated with open repair but also led to a decrease in the hernia recurrence rate. However, the rate continues to remain significant. A retrospective observational study was conducted on 193 patients who were treated with LVHR by two minimally invasive surgeons in a(More)
We consider how to avoid unsolicited e-mail – so called spam – in a stronger adversarial model than has previously been considered. Our primary concern is the proposal of an architecture and of protocols preventing against successful spamming attacks launched by a strong attacker. This attacker is assumed to control the communication media and to be capable(More)
BACKGROUND The advent of single incision laparoscopic surgery has brought renewed attention to cholecystectomy due to the promise of improved cosmesis and less parietal trauma. Small series have demonstrated the feasibility of single incision laparoscopic cholecystectomy (LC). Our series adds to the literature by demonstrating a variety of ancillary(More)
The purpose of this study was to demonstrate the feasibility of performing peroral endoscopic myotomy (POEM) in the management of recurrent achalasia after failed myotomy. Eight patients presented to our institution between October 2010 and June 2013 with recurrent/persistent symptoms after prior laparoscopic Heller myotomy. Three patients underwent redo(More)
Parastomal hernia (PH) is a frequent complication of stoma formation, occurring in 35–50 % of patients. Recurrence after repair is common, ranging from 24 to 54 % of cases. We hypothesized that repair using a laparoscopic modified Sugarbaker technique (SB) would result in a superior recurrence rate when compared with other repairs. An Institutional Review(More)
BACKGROUND Parastomal hernia (PH) is a frequent complication of stoma formation, and recurrence after repair is common. A laparoscopic modified Sugarbaker technique (SB) may decrease the recurrence of PH compared with other methods. METHODS A retrospective review, approved by the institutional review board, of patients who underwent PH repair between 2004(More)
BACKGROUND Little is known about the incidence of and associated management outcomes of occult hemothorax in blunt trauma patients. The increased use of computed thoracic tomography for the evaluation of the multiply injured blunt trauma patient has led to an increase in the identification of these hemothoraces and management dilemmas.
