Efficacy of Goal-Directed Fluid Therapy via Pleth Variability Index During Laparoscopic Roux-en-Y Gastric Bypass Surgery in Morbidly Obese Patients.
There is no well-recognized guideline for intraoperative fluid management in bariatric surgery. Goal-directed fluid therapy (GDFT) is a new concept of perioperative fluid management which was shown to improve patients' prognoses. Dynamic indicators may better predict fluid response compared to static indicators. In this study, we aimed to assess effects of administering GDFT protocol via Pleth Variability Index (PVI) in morbidly obese patients undergoing laparoscopic Roux-en-Y gastric bypass (RYGB) surgery. ⋯ There is no need to administer extra volume of fluid to obese patients undergoing laparoscopic bariatric surgery. Use of dynamic indicators like PVI helps to decrease intraoperative volume of infused fluids with no effects on either intraoperative or postoperative lactate levels in laparoscopic bariatric interventions.

Randomized Controlled Trial
Laparoscopic Sleeve Gastrectomy Versus Banded Roux-en-Y Gastric Bypass for Diabetes and Obesity: a Prospective Randomised Double-Blind Trial.
There are very few randomised, blinded trials comparing laparoscopic sleeve gastrectomy (LSG) versus laparoscopic Roux-en-Y gastric bypass (LRYGB) in achieving remission of type 2 diabetes (T2D), particularly silastic ring (SR)-LRYGB. We compared the effectiveness of (LSG) versus SR-LRYGB among patients with T2D and morbid obesity. ⋯ Despite significantly greater weight loss after SR-LRYGB, there was similar T2D remission and psychosocial improvement after LSG and SR-LRYGB at 1 year.

An increasing number of surgeons worldwide are now performing one anastomosis/mini gastric bypass (OAGB/MGB). Lack of a published consensus amongst experts may be hindering progress and affecting outcomes. This paper reports results from the first modified Delphi consensus building exercise on this procedure. ⋯ OAGB/MGB experts achieved consensus on a number of aspects concerning this procedure but several areas of disagreements persist emphasising the need for more studies in the future.

Laparoscopic sleeve gastrectomy (LSG) is widely used, and it is important to examine its physiologic and psychological efficacy among adolescents. We assessed LSG's efficacy for weight loss, its short- and long-term effects on resolving and improving obesity-related comorbidities, and its psychological outcomes among morbidly obese adolescents. ⋯ LSG significantly ameliorated short- and long-term obesity-related comorbidities and body image dissatisfaction among Qatari adolescents.

Clinical Trial
Visual Liver Score to Stratify Non-Alcoholic Steatohepatitis Risk and Determine Selective Intraoperative Liver Biopsy in Obesity.
Non-alcoholic fatty liver disease (NAFLD) and its progressive form, non-alcoholic steatohepatitis (NASH), are endemic in obesity. We aimed to evaluate the diagnostic accuracy and reproducibility of a simple intraoperative visual liver score to stratify the risk of NASH and NAFLD in obesity and determine the need for liver biopsy. ⋯ A simple, structured tool based on liver appearance can be a useful and reliable tool for NAFLD risk stratification and identification of patients who would most and least benefit from a biopsy. A normal liver appearance reliably excludes significant liver disease, avoiding the need for liver biopsy in patients otherwise at high clinical risk of NASH.
