Herbert F Gretz MD performs Robotic Surgery at Greenwich Hospital.


Greenwich Hospital is setting a new standard for minimally invasive surgical care using robotic assisted technology with the da Vinci Surgical System. Robotic technology offers patients an alternative to both traditional open surgery and conventional laparoscopy.

Traditional open surgery often requires incisions between 6-12 inches. Laparoscopic surgery, which involves the use of smaller incisions, can be effective for many routine procedures but has limitations when patients require more complex surgery. Robotic assisted technology allows surgeons to perform complex procedures with increased precision through tiny incisions, 1-2 cm long, using a console, high-definition monitor and four interactive robotic arms.

Advanced robotic technology is used primarily for urological and gynecological surgery.

Robotic technology offers patients an alternative to both traditional open surgery and conventional laparoscopy. The potential benefits include: Shorter hospital stay, Faster recovery, Less pain, Less scarring, Less blood loss and fewer transfusions, Fewer complications, Quicker return to normal activities, Better clinical outcomes in certain procedures

Greenwich Hospital surgeons and staff specialize in minimally invasive surgical techniques for a wide range of procedures, across virtually all surgical disciplines. Surgeries that once required extensive hospital stays and long periods for recovery and recuperation are now routinely done with this less invasive approach, often on an outpatient basis.

Using laparoscopic technology, specialized equipment and, at times, robotic assistance, the surgeons at Greenwich Hospital make tiny, precise movements through very small incisions. These innovative techniques cause minimal trauma to the body and offer significant advantages to surgical patients.



Our physicians are leading the way in global robotics development.With ever changing technology, you need someone on your side who knows how to treat complex problems.
