discussion the cholecystojejunocolic anastomosis with intussuscepted valve surgery could be considered as a forthcoming approach in the treatment of intrahepatic cholestasis. case presentation an 11-year-old girl with the diagnosis of pfic underwent cholecystoappendicostomy with myotomy operation. because of anastomosis stricture, she was reoperated with cholecystojejunocolic anastomosis and in...

OBJECTIVE Low pelvic anastomoses are associated with a high leak rate. Loop ileostomies are commonly performed during ileoanal and coloanal anastomoses. This study was undertaken to review our experience with loop ileostomy closure after low anterior rectal resection and restorative proctocolectomy. PATIENTS AND METHODS One hundred sixty five patients undergoing loop ileostomy closure at a si...

We introduce additively-weighted straight skeletons as a new generalization of straight skeletons. An additively-weighted straight skeleton is the result of a wavefront-propagation process where, unlike in previous variants of straight skeletons, wavefront edges do not necessarily start to move at the begin of the propagation process but at later points in time. We analyze the properties of add...

OBJECTIVE The aim of this study was to compare short-term results obtained with transanal total mesorectal excision (TME) and laparoscopic surgery. BACKGROUND Transanal TME appears as an alternative in the treatment of rectal cancer and other rectal disease. Natural orifices transluminal endoscopic surgery using the rectum as access in colorectal surgery is intuitively better suited than othe...

We characterize the self-parallel (mitered) offsets of a general nonconvex polytope Q in 3-space and give a canonical algorithm that constructs a straight skeleton for Q.
