Randomized Controlled Trial for Paclitaxel-coated Balloon versus Plain Balloon Angioplasty in Dysfunctional Hemodialysis Vascular Access: 12-month Outcome from a Nonsponsored Trial.

Background: Plain balloon angioplasty is regarded as the mainstay of treatment for failing vascular access with high success rate, but the poor treatment durability creates significant workload and increases patient morbidity. The study aims to compare target lesion primary patency rate at 12 months between paclitaxel-coated balloon (DCB) versus plain old balloon angioplasty (POBA) for treatment of dysfunctional vascular access.

Methods: This nonsponsored-randomized trial enrolled 40 patients with dysfunctional dialysis access at a single center.

Prospective randomized comparative study of single incision laparoscopic cholecystectomy versus conventional four-port laparoscopic cholecystectomy.

Background: This study aimed to compare the outcomes of single-incision laparoscopic cholecystectomy (SILC) versus conventional 4-port laparoscopic cholecystectomy (LC).

Methods: From November 2009 to August 2010, 51 patients with symptomatic gallstone or gallbladder polyps were randomized to SILC (n = 24) or 4-port LC (n = 27).

Results: Mean surgical time (43.
