The experience of the minimally invasive (MI) fellowship-trained (FT) hepatic-pancreatic and biliary (HPB) surgeon: could the outcome of MI pancreatoduodenectomy for peri-ampullary tumors be better than open?
Although early series focused on benign disease, minimally invasive pancreatoduodenectomy (MIPD) might be particularly suited for malignancy. Unlike their predecessors, fellowship-trained (FT) Hepatic-Pancreat...

Open AccessComparison between orogastric tube/bougie and a suction calibration system for effects on operative duration, staple-line corkscrewing, and esophageal perforation during laparoscopic sleeve gastrectomy
Placement of a bougie for sleeve sizing during laparoscopic sleeve gastrectomy (LSG) is recommended. We compared this standard with a suction calibration system (SCS) that performs all functions with one inser...
