More Information

Dr. Alessio Pigazzi specializes in minimally invasive colon and rectal surgery, including laparoscopic, robotic 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.

He also is skilled in robotic surgery for pelvic iatrogenic injuries, specifically recto-urethral and vaginal fistulas, and performs transvaginal colectomies for women seeking to avoid an abdominal scar.

In addition, Pigazzi 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.
