More Information

Dr. Alessio Pigazzi is a UC Irvine Health surgeon who specializes in minimally invasive colon and rectal surgery, including laparoscopic, robot-assisted and endoscopic techniques. He performed the world's first robot-assisted total mesorectal resection for rectal cancer, a procedure that results in faster recovery, better cosmesis and improved preservation of sexual function.

Pigazzi also is skilled in robot-assisted surgery for pelvic iatrogenic injuries, specifically recto-urethral and vaginal fistulas, and he performs transvaginal colectomies for women seeking to avoid an abdominal scar. In addition, he is an expert in hyperthermic intraperitoneal chemotherapy for peritoneal carcinomatosis. The procedure, combined with cytoreductive surgery, is an important and difficult-to-find option for patients with this complicated disease.

He earned a joint medical degree and PhD in biochemistry at Boston University School of Medicine. He completed an internship and residency in general surgery at New York-Presbyterian/Weill Cornell Medical Center, New York, N.Y. He completed a fellowship in minimally invasive surgery at Hackensack Medical Center in Hackensack, NJ, and a fellowship in colorectal surgery at UC Irvine Medical Center.
