BE-CALM: a clinical score to predict weight loss after conversion from sleeve gastrectomy to Roux-en-Y gastric bypass.

Background: Conversion from sleeve gastrectomy (SG) to Roux-en-Y gastric bypass (RYGB) may be indicated for patients due to insufficient weight loss or weight regain.

Objectives: To assess weight loss outcomes and factors predictive of improved weight loss in patients undergoing RYGB after SG and create an algorithm to estimate postoperative weight loss in these patients.

Setting: University Hospital.

Routine extended (30 days) chemoprophylaxis for patients undergoing laparoscopic sleeve gastrectomy may reduce Portomesenteric vein thrombosis rates.

Background: Venous thromboembolism (VTE), including Portomesenteric vein thrombosis (PMVT), is a major complication of sleeve gastrectomy (SG). We changed our practice in July 2021 to routinely discharge all SG patients postoperatively with extended chemoprophylaxis for 30 days.

Objectives: Evaluate the efficacy and safety of routine extended chemoprophylaxis compared to 2 prior timeframes using selective extended chemoprophylaxis.

Striking Size Reduction of Rapidly Growing Pancreatic Neuroendocrine Carcinoma Metastatic Nodal Conglomerate After Only 2 Cycles of 177 Lu-DOTATATE.

Peptide receptor radionuclide therapy (PRRT) with 177 Lu-DOTATATE has shown great treatment efficacy in patients with well-differentiated metastatic neuroendocrine tumors and a metastatic size reduction of ~20% for metastatic lesions <3 cm in size. We present a 66-year-old man with pancreatic neuroendocrine carcinoma, who had a rapidly growing metastatic nodal conglomerate, which measured close to 10 cm in size. After only 2 cycles of PRRT with 177 Lu-DOTATATE, the nodal conglomerate had a striking size reduction greater than 75%.

Thrombophilia prevalence in patients seeking laparoscopic sleeve gastrectomy: extended chemoprophylaxis may decrease portal vein thrombosis rate.

Background: Portomesenteric vein thrombosis (PMVT) may occur after laparoscopic sleeve gastrectomy (LSG). Previous studies have shown that PMVT patients may have undiagnosed thrombophilia. We recently changed our practice to check thrombophilia panel in every LSG patient preoperatively.
