OBJECTIVE The aim of this study was to investigate the effect of postoperative peritoneal infection on proliferation, migration, and invasion capacities of cancer cells lines in vitro after surgery for colorectal cancer. BACKGROUND Anastomotic leakage is associated with higher rates of recurrence after surgery for colorectal cancer. However, the(More)
BACKGROUND Anastomotic leakage is associated with higher rates of recurrence after surgery for colorectal cancer. However, the mechanisms responsible are unknown. The aim was to investigate the inflammatory and angiogenic responses in patients undergoing surgery for colorectal cancer who had postoperative intra-abdominal infection, and to compare the(More)
INTRODUCTION Recto-urethral fistula is an uncommon complication after radical prostatectomy, occurring in less than 2% of patients.
