Roux-en-Y gastric bypass surgery (RYGB) is an effective treatment for patients with type 2 diabetes (T2DM). Tight glycaemic control immediately after RYGB for T2DM may improve long-term glycaemic outcomes, but is also associated with a higher risk of hypoglycaemia. We designed a treatment algorithm to achieve optimal glycaemic control in patients with insulin-treated T2DM after RYGB and evaluated its feasibility, safety and efficacy. ⋯ The protocol-driven management proved to be feasible, safe and effective in achieving targeted glycaemic control in T2DM after RYGB. The next step will be to scrutinise the efficacy of protocol-driven management in a randomised controlled clinical trial.

Thromboelastography is a technique that surveys the properties of viscoelastic blood clot. The purpose of this paper was to evaluate the hypercoagulability state and the effect of antithrombotic prophylaxis on thromboelastogram (TEG) results in bariatric surgery. ⋯ Our patients presented a tendency to hypercoagulability determined most by MA and GI. Comparison between TEGs indicates that low-molecular-weight heparin not titrated on weight is able to determine a reduction of hypercoabulable tendency in the early postoperative period with few effects on increasing MA and GI.

An increasing number of morbidly obese patients with end stage renal disease (ESRD) are sequentially undergoing bariatric surgery followed by renal transplantation. Discrepancies between the nutritional recommendations for obesity and chronic kidney disease (CKD) are often confusing for the obese patient in renal failure. However, when recommendations are structured according to stage and treatment of disease, a consistent plan can be clearly communicated to the patient. Therefore, to optimize patient and graft outcomes we present nutritional recommendations tailored to three patient populations: obese patients with ESRD, patients post Roux-en-Y gastric bypass (RYGBP) with ESRD, and patients post RYGBP and post renal transplantation.

Comparative Study
Impact of bariatric fellowship training on perioperative outcomes for laparoscopic Roux-en-Y gastric bypass in the first year as consultant surgeon.
There have been few reports of improved perioperative outcomes for laparoscopic gastric bypass in the surgeon's independent practice following completion of fellowship training but none from outside of USA. The aim was to evaluate the impact of fellowship training on perioperative outcomes for gastric bypass in the first year as consultant surgeon. Data of all patients undergoing primary bariatric procedures by the author were extracted from prospectively maintained database. ⋯ As compared with host training institution, the OS-MRS distribution and perioperative outcomes of the author did not differ significantly from that of mentors' post-learning curve results. Bariatric fellowship ensured skills acquisition for the author to safely and effectively perform gastric bypass without any learning curve and with surgical outcomes similar to that of experienced mentor at host training institution. Fellowships should be an essential part of bariatric training worldwide.

Comparative Study Clinical Trial
Incisional hernia prophylaxis in morbidly obese patients undergoing biliopancreatic diversion.
The development of incisional hernia after open bariatric surgery is a major cause of morbidity and hospital readmission. The use of prosthetic material in clean-contaminated procedures remains controversial and correlated to high rate of local complications. A prospective observational clinical study on two different surgical techniques used to close the abdominal wall has been performed to better assess the safety (primary end point) and the efficacy (secondary end point) of polypropylene mesh placement to prevent incisional hernia in morbidly obese patients undergoing biliopancreatic diversion (BPD). ⋯ The mesh placement in clean-contaminated bariatric surgery seems to be safe (primary end point) and effective (secondary end point) at 1-year follow-up.
