Robot-Assisted Surgery

Laparoscopic & Robot-Assisted Surgery

Robot-assisted weight loss surgery is the latest technique in laparoscopic surgery. Many refer to laparoscopic and robot-assisted surgery as “minimally-invasive” surgery because it is performed through very small incisions in the abdomen, to differentiate it from traditional open abdominal surgery through an upper abdominal incision. Benefits of minimally-invasive laparoscopic and robot-assisted surgery include less chance of infection and hernias, less post-operative pain and faster recovery, enabling patients to leave the facility within a day and return to work faster. Surgery has evolved considerably in the past 10 years, from traditional open surgery to laparoscopic and robot-assisted surgery.

Laparoscopic Surgery
Dr. Srikanth has performed more than 3,000 laparoscopic weight loss surgeries. The laparoscopic approach allows the surgeon to perform surgery through a few small, half inch incisions. Small tubes called “trocars” are introduced which guide long chopstick-like instruments into the abdomen. Visibility is provided through a magnified image generated on a monitor by a long telescope.

Robot-Assisted Surgery
The robot-assisted approach is the latest technique in laparoscopic surgery. The “robot” is a four-armed “surgical machine” that is incapable of independent function, meaning it’s under the complete control of the surgeon. The surgeon works through a console with the help of a specially-trained surgical assistant and crew. Surgery is performed using small incisions and metallic trocars which provide precisely-controlled three-dimensional movement.  The camera has dual optic channels and zoom capabilities which provide a highly magnified true 3D-HD vision within the abdomen. Robotic instruments have a miniature wrist that works much like the human hand—except they can rotate 570 degrees and can work tirelessly. This allows for remarkable dexterity, precision and the ability to sew around corners.

The “robot” combines the benefits of laparoscopic surgery (small incisions, less post-op discomfort and faster recovery) with the advantages of traditional open surgery (freedom of movement and improved dexterity for the operator) which results in an overall outstanding surgical experience for our patients.

Dr. Srikanth is one of the few surgeons in the Pacific Northwest who performs the robot-assisted duodenal switch. This surgery has well-documented success rates (>90%) for excellent long-term weight loss and diabetes control.
