Comparative Study Observational Study
Comparison of Repeat Sleeve Gastrectomy and Roux-en-Y Gastric Bypass in Case of Weight Loss Failure After Sleeve Gastrectomy.
Few series are available on the results of repeat sleeve gastrectomy (re-SG) and Roux-en-Y gastric bypass (RYGB) performed to manage the failure of primary sleeve gastrectomy (SG). The objective of this study was to compare the short- and medium-term outcomes of re-SG and RYGB after SG. ⋯ Re-SG and RYGB as revisional surgery for SG are feasible with acceptable outcomes and similar results on weight loss on the first postoperative year.

Randomized Controlled Trial
Apneic Oxygenation During Prolonged Laryngoscopy in Obese Patients: a Randomized, Double-Blinded, Controlled Trial of Nasal Cannula Oxygen Administration.
Obese patients have a propensity to desaturate during induction of general anesthesia secondary to their reduced functional residual capacity and increased oxygen consumption. Apneic oxygenation can provide supplemental oxygen to the alveoli, even in the absence of ventilation, during attempts to secure the airway. In this study, we hypothesized that oxygen administration through a nasopharyngeal airway and standard nasal cannula during a simulated prolonged laryngoscopy would significantly prolong the safe apneic duration in obese patients. ⋯ In obese patients, oxygen insufflation at 15 L/min through a nasopharyngeal airway and standard nasal cannula can significantly increase the safe apneic duration during induction of anesthesia.

Bariatric surgery reduces atherosclerotic cardiovascular disease (ASCVD) risk. However, the comparative effect of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) on 10-year and lifetime ASCVD risk, as defined by the American College of Cardiology/American Heart Association (ACC/AHA), remains unknown. ⋯ Although RYGB and SG significantly lower 10-year and lifetime cardiovascular disease risks by 1 year after surgery, patients who undergo RYGB may experience greater cardiovascular risk reduction relative to counterparts who undergo SG.

To compare non-fatal cardiovascular (CV) events and metabolic outcomes, among obese patients with insulin-treated type 2 diabetes who underwent bariatric surgery compared with a propensity-matched non-bariatric cohort. ⋯ Among obese insulin-treated patients with type 2 diabetes, bariatric surgery is associated with significant reductions in non-fatal CHD and PAD events, lower body weight, HbA1c, BP and a greater likelihood of insulin independency during 10 years of follow-up.

Internal hernia is a rare but a potentially fatal complication of laparoscopic Roux-En-Y gastric bypass (LRYGB). The aims of this study are to determine the impact of mesenteric defects closure on the incidence of internal hernia after LRYGB and to determine the symptoms, characteristics, and management of internal hernias after LRYGB. ⋯ The closure of mesenteric defects during LRYGB is recommended because it is associated with a significant reduction in the incidence of internal hernia.
