Our office provides a variety of services from routine colorectal cancer screenings to management of patients with liver disease, cirrhosis and those who may be interested in non-surgical weight loss balloon.


Routine Colorectal cancer screening

Colon cancer is one of the most preventable types of cancer.

Guidelines recommend cancer screenings beginning at age 50 and even earlier for those at higher risk.

Liver disease

This may include patients with "fatty liver," hepatitis, cirrhosis and ascites.


Complex conditions

We also treat complex GI conditions such as

-Crohn's/ Ulcerative Colitis


-Peptic Ulcer Disease

-Barrett's Esophagus

-Other conditions within the gastrointestinal system.

No more ointments, creams or suppositories. With onset occurring after the age of 30, hemorrhoids affect more than half the population at some point in their lives.

Unlike other techniques that use a metal clamp to grasp the hemorrhoid during banding, we use a smaller, gentler, single use and disposable suction device to minimize discomfort and complications.

The CRH O'Regan System is a simple painless and highly effective procedure (99.1%) that can be preformed in less than a minute. How simple?  Dr Mastali will place a tiny rubber band around the internal hemorrhoid to cut of its bloody supply. The hemorrhoid then shrinks and falls off within a day or so, usually without you noticing and that's it. Once the hemorrhoid is gone, so are your symptoms. The CRH O'Regan System is the only hemorrhoid removal treatment that requires no pain medication and virtually no recovery time. In fact, many of our patients with office jobs return to work following the appointment. Other rest at                                                                                                                             home afterwards and resume normal activities the next day.

                               Hemorrhoid Classification:

           Grade 1- Hemorrhoid bleeds but doesn't prolapse outside of the anal canal

           Grade 2- Prolapses, usually with defecation, but retracts spontaneously

           Grade 3- Requires manual reduction into the anal canal after prolapsing

           Grade 4 Prolapsing tissue cannot be manually replaced and may be strangulated or thrombosed.
