Bariatric surgery in obese patients is a highly effective method of preventing or resolving type 2 diabetes mellitus (T2DM); however, the remission rate not same among different surgical procedures. We compared effects 20% weight loss induced by laparoscopic adjustable gastric banding (LAGB) Roux-en-Y bypass (RYGB) on metabolic response to mixed meal, insulin sensitivity, and β cell function nondiabetic adults. The meal ingestion was markedly after RYGB than LAGB surgery, manifested rapid...
Background Determination of intra-abdominal injury following blunt abdominal trauma (BAT) continues to be a diagnostic challenge. Ultrasound (US) has been described as potentially useful tool in this setting and is being used with increasing frequency centers. We determined the capability US evaluation BAT. Methods A retrospective analysis our database was performed over 30-month period. Computed tomographic scan, peritoneal lavage, or exploratory laparotomy confirmed presence injury....
Findings have shown that single-incision laparoscopic cholecystectomy (SILC) is feasible and reproducible. The authors pioneered a two-trocar SILC technique at the University of Texas Southwestern. Their results for 100 patients are presented. From January 2008 to March 2009, with symptomatic gallbladder disease underwent through 1.5- 2-cm umbilical incision using two-port (5-mm) technique. For nearly all patients, 30° angled scope was used. retracted, two or three sutures placed along...
We compared the impact of two-dimensional (2D) versus three-dimensional (3D) visualization on both objective and subjective measures laparoscopic performance using validated Fundamentals Laparoscopic Surgery (FLS) skill set.Thirty-three individuals with varying experience completed three essential drills from FLS set (peg transfer, pattern cutting, suturing/knot tying) in 2D 3D. Participants were randomized to begin all tasks either or Time completion number attempts required achieve...
The Medicare Coverage Advisory Committee recently concluded that evidence supports the safety and effectiveness of bariatric surgery in general adult population. However, more information is needed on role elderly. aim this study was to examine outcome elderly performed at academic centers. Using International Classification Diseases, 9th Revision diagnosis procedure codes, we obtained data from University HealthSystem Consortium Clinical Data Base for all (>60 years) nonelderly (19–60...
In Brief Background: Although laparoscopy now plays a major role in most general surgical procedures, little is known about the relative risk of venous thromboembolism (VTE) after laparoscopic compared with open procedures. Objective: To compare incidence VTE and surgery over 5-year period. Patients Interventions: Clinical data patients who underwent or appendectomy, cholecystectomy, antireflux surgery, gastric bypass between 2002 2006 were obtained from University HealthSystem Consortium...
To determine the utility of near-infrared spectroscopy in diagnosis lower extremity compartment syndrome (CS).Nine patients with CS confirmed by physical examination and elevated pressures (64 +/- 17 mm Hg) were evaluated before after fasciotomy. Control readings also performed on 33 surgical who had no evidence CS. The deltoid muscle was used as a reference value.The oxygen saturation (StO2) revealed mean = 84 17% prefasciotomy 83 12% postfasciotomy group. control group StO2 11%. In group,...
To determine the optimal method of wound closure for dirty abdominal wounds.The rate infection wounds is approximately 40%, but remains controversial. Three randomized studies comparing delayed primary (DPC) with (PC) have not conclusively shown any advantage one over other in terms infection.Fifty-one patients related to perforated appendicitis, viscus, traumatic injuries more than 4 hours old, or intraabdominal abscesses were enrolled. Patients stratified by cause (appendicitis vs. all...
Objective The effects of marked weight loss, induced by Roux‐en‐Y gastric bypass (RYGB) or sleeve gastrectomy (SG) surgeries, on insulin sensitivity, β‐cell function and the metabolic response to a mixed meal were evaluated. Methods Fourteen nondiabetic insulin‐resistant patients who scheduled undergo SG ( n = 7) RYGB procedures completed hyperinsulinemic‐euglycemic clamp procedure mixed‐meal tolerance test before surgery after losing ∼20% their initial body weight. Results Insulin...
Hypertension is a well-recognized and treatable risk factor for coronary heart disease one of the most common comorbidities associated with obesity. The aim this study was to characterize clinical outcome cohort patients documented hypertension who underwent laparoscopic gastric bypass.
