BACKGROUND The BPD/DS has better resolution of diabetes and hypercholesterolemia, and the best long-term weight loss compared to the laparoscopic gastric band or the(More)
Minimally invasive surgical techniques decrease the length of hospitalization and the morbidity for general surgery procedures. Application of minimally invasive techniques to obesity surgery had previously been limited to stapled techniques used primarily for the Roux-en-Y gastric bypass and laparoscopic band placement. The authors present the technique(More)

Descriptive statistics were used for demographics of Whites, Blacks, or Hispanics undergoing RYGB with 1 year of follow-up, between June 2007 and October 2011. Multivariate logistic and normal(More)
BACKGROUND AND PURPOSE The use of the da Vinci robot is being investigated in the discipline of urologic surgery. We describe our experience with its use during radical cystoprostatectomy in two patients with organ-confined bladder cancer. PATIENTS AND METHODS Laparoscopic radical cystoprostatectomy with ileal conduit urinary diversion was performed using(More)
Despite the relative common incidence of accidental foreign body ingestion in the general population, foreign bodies are estimated to only infrequently result in intestinal perforation or other complications. Bowel perforations resulting from unintentional foreign body ingestion are exceedingly difficult to diagnose preoperatively, and often, the patient(More)

However, no normative data are available to aid the bariatric surgeon in assessing the adequacy of weight loss at each postoperative visit. The objective of the present study was to construct nomograms to aid in the assessment of weight loss. The setting was a university hospital in the(More)
