Q: When is minimally invasive surgery better than traditional surgery?

A: When the same operation can be done with a few small incisions, healing is quicker and easier.

Q: What are the advantages of endoscopic surgery?

A: Magnified high definition images enable very precise and delicate surgery.

Q: What questions should patients ask their surgeon about this approach?

A: Can my procedure be done with minimally invasive techniques, are the technical skills and equipment available to provide this type of surgery.

Q: What is your training?

A: I learned minimally invasive surgery in my Surgical Residency and have worked extensively in Minimally Invasive Surgery for the past 18 years.

Q: If MIS a "minor" surgery, does it require general anesthesia in every case?

A: Most abdominal Minimally Invasive procedures do require General Anesthesia but since we use local anesthesia and small incisions, less General Anesthesia is required.

Q: There are several terms for this type of surgery used- endoscopic, laparoscopic, minimally invasive - what are the differences in these medical terms, if any?

A: Endoscopic usually refers to scopes that look at the inside of the stomach and colon,  this is usually done with sedation.   Laparoscopic generally involves a scope that is placed through a small port into the abdomen,   Minimally invasive is similar to laparoscopic but may involve even smaller incisions.
