Youngstown Minimally Invasive Surgeon

Surgeon Dr. Dennis Orr

Minimally Invasive Surgery (MIS) is surgery performed through small incisions with specialized instruments and a small camera. Youngstown Minimally Invasive Surgeon Dr. Dennis Orr performs surgery with robotic precision, literally. The image is magnified and projected on widescreen for superior visualization of the anatomy.

It is the best choice for many surgical procedures including gallbladder removal, hernia repair, colon removal, spleen removal, & antireflux (GERD) treatment. When compared to traditional open surgery, MIS offers many benefits including less pain, better cosmetic incisions, quicker return to normal activity, fewer wound infections, & post-operative hernias.

While many general surgeons perform laparoscopic procedures, a “minimally invasive” or “laparoscopic surgeon” who is fellowship-trained, spent an additional year of training at large-volume, tertiary care centers specializing in these procedures. Based on the surgeon’s skill, more advanced surgeries may be performed laparoscopically and basic procedures may be successfully completed laparoscopically without converting to a traditional, open incision. Conversion is usually done when the surgeon is not progressing with the surgery or can not complete the procedure safely.

Colonoscopy is a procedure where a surgeon passes a flexible camera about the size of your index finger in the anus and passes throughout the colon. It is usually performed under moderate sedation where the patient is sleeping but able to breathe on their own.

Esophageal Motility Disorders

Normal swallowing causing pressure waves to move down the esophagus to propel food and water into the stomach. In contraction, esophageal motility disorders may include simultaneous contraction, loss of contraction, and abnormally high or low contractions.

Inguinal (Groin) Hernia

Inguinal hernia is a defect (space) in the groin in which the inner lining of the abdomen in its contents bulges through. This may cause pain. The blood supply can get choked off, resulting in death and perforation of the intestinal contents, which may be life-threatening.


Hyperparathyroidism is a condition where the body produces too much parathyroid hormone. The parathyroid hormone pulls calcium out of the body and elevates the levels in the blood. This leads to lower levels in the bones, and higher levels in the blood and urine.
