Colon & Rectal
Dr. Charbel and Dr. Kamal understand the fear, embarrassment, and concern many patients face, so they work compassionately and diligently to help you understand your specific condition, what’s at stake, options and recommended therapies.
Dr. Patel, Dr.Richardson, Dr.Ringley, Dr. Sugimoto, and Dr. Valdez are board certified general surgeons with a broad range of surgical experience and expertise.
Dr. Patel serves as Medical Director of Trauma at Covenant HealthCare, the region’s only Level II Trauma Center for adults and children. Dr. Richardson, Dr. Sugimoto, and Dr. Valdez assist with trauma care.
Dr. Valdez is fellowship trained in both Critical Care and Trauma & Acute Care Surgery. She provides surgical management of traumatically injured patients and those requiring emergency general surgery.
Our surgeons employ a variety of advanced surgical procedures. All are minimally invasive, which reduces pain, scarring, blood loss and recovery time for patients.
This surgical technique allows abdominal surgery to be performed through significantly smaller incisions (usually 0.5–1.5 cm) than those more traditionally used. Sometimes these surgeries are aided by images displayed on TV monitors mounted in the operating room for magnification purposes.
The instrument used to perform this surgery is called a laparoscope. The surgical procedure itself begins by filling the patient’s abdomen with carbon dioxide to blow it up like a balloon. This elevates the abdominal wall above the internal organs in a dome-like fashion creating both viewing and working space. The laparoscope, with an attached light source, is inserted through the small incision site and the surgical procedure is performed. When completed, the scope is removed, the site sutured, and the carbon dioxide – a natural bodily substance – is absorbed by surrounding tissues.
Transoral Incisionless Fundoplication (TIF)
TIF is an incisionless procedure appropriate for treating patients who suffer from acid reflux disease (also known as GERD). GERD is caused by a weakening of the valve between the esophagus. When the valve deteriorates from such things as excessive weight, poor diet and aging, its ability to function is compromised and GERD results. Heartburn is the most typical symptom of GERD.
TIF treats the underlying cause of GERD without incisions. During the procedure the anti-reflux valve is reconstructed and its natural ability to protect against reflux restored. TIF is safe, effective, has a rapid recovery time and minimal side effects. The majority of patients who have had the treatment report improved quality of life, reduction and/or elimination of heartburn symptoms, and the ability to eliminate daily medications for GERD.
As a low risk solution for GERD, TIF may be appropriate for those who:
- no longer adequately respond to or are dissatisfied with pharmaceutical therapies
- are increasingly experiencing heartburn and other bothersome symptoms of GERD
- are concerned about the long-term effects of taking medications
Robotic Assisted Surgery
Our patients now have the option of an effective alternative approach to the traditional open surgery and/or laparoscopy. The da Vinci Surgical System allows our surgeons to operate with the precision of a robot and the power of a three-dimensional microscope for excellent clinical outcomes. With this tool, surgeons are better able to visualize the anatomy of the patient to perform effective and efficient surgeries. In place of conventional laparoscopic surgery for a major operation, the daVinci surgery system operates with small instrumentation and smaller incisions. The benefit for patients is minimal pain before, during and after surgery and decreased recovery time.
