|Full paper||Not Available|
Objectives: To evaluate short-term effects of low anterior resection using either open or laparoscopic approach on erectile function (EF) and sexual performance of rectal cancer patients. Patients & Methods: The study included 60 male patients with mean age of 57.9±5.6 years; 45 had TO tumors, while 15 patients had TI tumors and 51 patients had NO and 9 patients had NI nodal involvement. All patients had low anterior rectal resection (RR) according to the standard total mesorectal excision (TME) with identification of the hypogastric and autonomic nerves using either laparoscopic (Lap RR) or open (Open RR) approach. All patients underwent evaluation of EF using the International Index of Erectile Function (IIEF-5) and sexual function and performance using the Brief Male Sexual Function Inventory (BMSFI) preoperatively and at 6 postoperative (PO) months.
