Minimally Invasive Colorectal Surgery
Our colorectal surgeons take a minimally invasive approach to each operation whenever appropriate. They are highly experienced in the use of robotic surgery, using advanced tools to operate through smaller incisions with exceptional precision. The result: less pain after surgery, smaller scars, and a quicker recovery than conventional open abdominal surgery.
Our surgeons try to avoid the need for an ostomy bag (a bag worn outside the abdomen to collect waste) whenever possible. Should you need a more extensive or complex operation or if you have multiple health problems, we can perform your surgery at NewYork-Presbyterian/Columbia University Irving Medical Center.
Helping You Recover
It may take a few days after your surgery for your bowel habits to resume. Our goal is to shorten your hospital stay and get you home so you can return to the activities you enjoy. Your team helps you recover by:
- Giving you dietary advice to restore your bowel activity
- Helping you get out of bed and moving again
- Avoiding narcotic painkillers (which can be constipating) whenever possible
If after your colorectal surgery you need a permanent colostomy or ileostomy, our ostomy nurses have the compassion and experience to support you as you adapt to life with an ostomy.
