Predictors of type-2 diabetes remission following bariatric surgery after a two-year follow-up.

PURPOSE: Bariatric surgery is evolving as a successful tool for managing morbid obesity and T2DM. This study aimed to identify predictors of diabetes remission after two types of bariatric procedures. METHODS: This prospective study enrolled 172 patients with morbid obesity associated with T2DM scheduled for bariatric surgery. Two laparoscopic bariatric procedures were done; single anastomosis gastric bypass (SAGB, n = 83) and sleeve gastrectomy (LSG, n = 68). Lipid accumulation product index (LAP) and quantitative insulin sensitivity check index (QUICKI) were used to evaluate lipid profile and insulin sensitivity. Two years after surgery condition of DM was evaluated as complete remission (CR), partial remission (PR), or improvement. The primary outcome measure was predictors of diabetes remission. RESULTS: Two years after surgery, 151 patients were available for evaluation, where 75 patients (49.7%) achieved CR, while PR was found in 36 (23.8%). CR was significantly associated with younger age, shorter duration of DM (p < 0.001, for both), higher C-peptide and GLP-1 levels (p < 0.001 and p = 0.002, respectively), and bypass surgery (p = 0.027). On multivariate analysis, shorter duration of DM, lower BMI, and higher C-peptide levels were the independent factors predicting CR. CONCLUSION: Complete remission of T2DM can be achieved in nearly half of the patients two years after SG or SAGB. The duration of diabetes and preoperative BMI and C-peptide levels are the independent factors predicting complete remissions.

Study of factors affecting Small for Size Syndrome Post-Adult living donor liver transplantation.

AIM: Recently, increasing evidence showed that small-for-size syndrome (SFSS) is a multifactorial disease which is precipitated by various perioperative factors other than graft size. We conducted the current work to evaluate perioperative effectors, which can increase the risk of SFSS following adult living-donor liver transplantation (LDLT). METHODS: This is a retrospective study on 110 adult cirrhotic cases (mean age of 48.4 ± 6.9 years old) who underwent adult LDLT. Most cases were males (89%). Cases were categorized into two groups based on the occurrence of SFSS. The groups were compared regarding preoperative (gender, age, comorbidities, baseline investigations), intraoperative (mean blood pressure and glucose; mean operation time; number of packed red cells, plasma, platelets, and cryoprecipitate units; time of cold and warm ischemia, and anhepatic phase; preclamping and post-reperfusion portal pressures), and postoperative factors (relevant investigations, hospital stay). RESULTS: Postoperatively, 23 patients developed SFSS (20.9%). SFSS group had significantly lower preoperative graft recipient weight ratio (GRWR) (0.76 ± 0.1% versus 1.03 ± 0.15, respectively; p < 0.001), and elevated MELD scores (19 ± 2.1 versus 17.9 ± 4; p = 0.024). Preclamping and post-reperfusion portal pressures of ≥22.5 and 17.5 mmHg, exhibited a sensitivity of 95.7% and 91.3% and specificity of 87.4% and 88.9% respectively, for SFSS prediction. CONCLUSION: SFSS risk is significantly linked to GRWR, MELD score, and intraoperative portal haemodynamics. Intraoperative portal haemodynamics exhibited good diagnostic accuracy for SFSS prediction and represented promising indicators for the prediction of SFSS.
