General surgery is a surgical specialty that focuses on abdominal contents including the esophagus, stomach, small bowel, colon, liver, pancreas, gallbladder, appendix and bile ducts, and often the thyroid gland. A general surgeon performs a wide range of abdominal surgeries for many forms of intestinal and abdominal wall neoplasms, gallbladder disease, gastric and pancreatic disease. They follow the patient through critical care and surgical recovery all the way to outpatient care. 

Bariatric surgery is a medical term for surgical procedures used to manage obesity and obesity-related conditions. Long term weight loss with bariatric surgery may be achieved through alteration of gut hormones, physical reduction of stomach size, reduction of nutrient absorption, or a combination of these. Surgeons trained in this specialty are known as bariatric surgeons. 

Attributing his success to his genuine and profound concern for his patients, Dr. Pirrello emphasizes their well-being as his top priority.
