Why Choose Johns Hopkins for Colorectal Surgery?
Multidisciplinary Care
Our multidisciplinary care team consists of surgeons, nurses and other healthcare providers across multiple divisions to create the best treatment plan. We specialize in treating patients of all ages diagnosed with any colorectal disease.
Treatment for all Anal, Colon and Rectal Conditions
Johns Hopkins is one of the few institutions that offers the 5x5 protocol, a comprehensive treatment for rectal cancer. We provide advanced surgical treatment including robotic-assisted and laparoscopic surgery for all anal, colon and rectal conditions.
Convenient and Accessible Care
We offer patients timely access to care by scheduling appointments within one to two weeks as well as providing care through telemedicine.
Our Advanced Surgical Treatments
Your physician will talk with you about the best treatment option for your condition. We provide the following surgical treatments for colorectal cancer and diseases:

Our colorectal surgeons at Johns Hopkins continue to lead innovation in surgical advancements aimed at colon and rectal cancer therapies.
What is the 5x5 protocol?
The 5x5 protocol administers 5 grays (Gy) of radiation for five days for a total of 25 Gy in combination with full-dose chemotherapy for advanced rectal cancer. As a result, patients receive a more consolidated dose of chemotherapy and radiation therapy prior to surgery. This systemic approach is a break from the more conventional method of delivering radiation over a longer five-week period.
Advantages of the 5x5 protocol
- A shorter, more aggressive approach to rectal cancer treatment
- Ability to deliver chemotherapy prior to surgery
- More convenient for patients
The future of the 5x5 protocol
Johns Hopkins researchers will soon publish the results from a 5x5 protocol study and the outcomes of 30 to 40 patients who have undergone this procedure, nationally.
Your surgeon will work with you to determine the best treatment plan based on your diagnosis and circumstance.

Cytoreductive surgery (CRS), also known as tumor debulking, and hyperthermic intraperitoneal chemotherapy (HIPEC) involves the surgical removal of the tumor followed by delivering heated chemotherapy drugs into the abdomen.
This surgical technique provides more treatment options for patients diagnosed with late stage cancers.

We provide several minimally-invasive surgical techniques which can reduce the risk of infection, pain and shorten your recovery time. One minimally-invasive technique we practice is laparoendoscopic surgery which can remove failing organs through one small incision through the skin.

We offer robotic-assisted surgery which allows surgeons to perform less invasive and more precise surgical procedures through the use of a console which controls the surgeons movements.

Transanal endoscopic microsurgery (TEM) allows surgeons to remove a polyp or superficial lesion through the anus, without making an incision.
