Benefits of Robotic Surgery

Robotic surgery offers many benefits to patients compared to open surgery, including:

  •  Shorter hospitalization
  •  Reduced pain and discomfort
  •  Faster recovery time and return to normal activities
  •  Smaller incisions, resulting in reduced risk of infection
  •  Reduced blood loss and transfusions
  •  Minimal scarring


Major advantages for surgeons using robotic surgery include:

  •  Greater visualization
  •  Enhanced dexterity
  •  Greater precision

Robotic surgery is an advanced form of minimally invasive or laparoscopic (small incision) surgery where surgeons use a computer-controlled robot to assist them in certain surgical procedures. The robot’s “hands” have a high degree of dexterity, allowing surgeons the ability to operate in very tight spaces in the body that would otherwise only be accessible through open (long incision) surgery.

Compared to open surgery (traditional surgery with incisions), robotic and minimally invasive surgery results in smaller incisions resulting in less pain and scarring.

Robotic surgery allows surgeons to perform complex surgical tasks through tiny incisions using robotic technology. Surgical robots are self-powered, computer-controlled devices that can be programmed to aid in the positioning and manipulation of surgical instruments. This provides surgeons with better accuracy, flexibility and control.

When performing robotic surgery using the da Vinci Surgical System:

  •  The surgeon works from a computer console in the operating room, controlling miniaturized instruments mounted on three robotic arms to make tiny incisions in the patient.
  •  The surgeon looks through a 3-D camera attached to a fourth robotic arm, which magnifies the surgical site.
  •  The surgeon’s hand, wrist and finger movements are transmitted through the computer console to the instruments attached to the robot’s arms. The mimicked movements have the same range of motion as the surgeon allowing maximum control.
  •  The surgical team supervises the robot at the patient’s bedside.

Dr. Ashish Vashistha is trained and experienced robotic & laparoscopic surgeon who performs the following general surgery procedures:

General Surgical procedures for the digestive tract –

Gastrointestinal tract surgical procedures

1. Bariatric Surgery ( Weight loss surgery)

Robotic bariatric surgical procedures are offered to patient with high Body Mass Index (BMI) and other medical conditions related to obesity. Also good results are seen in revisional bariatric surgery cases.

The main advantages of Robotic system are seen with Gastric by pass.

  •  A 3D HD View inside our body
  •  Wristed instruments that bend and rotate far greater than human hand.
  •  Enhanced vision, precision and control
  •  Low rate of gastro intestinal leaks.
  •  Better stoma size.
  •  Avoidance of stapler costs
  •  No wound infection.

Colectomy surgery: Robotic-assisted colectomy surgery removes part or all of the colon, or large intestine, to treat conditions including colorectal cancer, small growths called polyps, diverticular disease and inflammatory bowel diseases.

Gastrectomy: Robotic-assisted gastrectomy surgery is partial or complete removal of the stomach. This surgical procedure may be performed to remove benign (non-cancerous) or malignant (cancerous) tumors or treat bleeding or inflammation of the stomach lining.

Heller myotomy: Robotic-assisted heller myotomy is a surgical procedure used to treat achalasia, a disorder of the esophagus that makes it difficult to swallow solids or liquids. This procedure improves swallowing by relaxing the sphincter between the esophagus and the stomach.

Nissen fundoplication: One of the treatments for gastroeshphageal reflux disease (GERD), Nissen fundoplication with surgical robots reinforces the sphincter between the esophagus and stomach to reduce acid backup from the stomach into the esophagus.

Rectopexy: Robotic rectopexy surgery repairs rectal prolapse, a condition in which tissue from the rectal wall protrudes through the anus. No bowel resection is required.

2. Solid Organ Surgery

Adrenalectomy: Located above each kidney, the adrenal glands produce hormones such as epinephrine, estrogen and cortisol. Robotic adrenalectomy surgery removes one or both of the adrenal glands.

Liver and bile duct resection: Robotic-assisted liver and bile duct resection may be used to remove malignant (cancerous) growths from the liver or bile ducts. Benign (non-cancerous) growths may also need to be removed if they cause blockages or other problems.

Nephrectomy: Robotic nephrectomy is the removal of all or part of a kidney due to cancer, disease or severe damage.

Pancreatectomy: Conditions including pancreatic cancer, benign tumors and pancreatitis may be treated by robotic-assisted pancreatectomy to remove part or all of the pancreas.

Robotic cholecystectomy: The gallbladder is a pear-shaped organ under the liver that helps digest fat. If it becomes inflamed, infected, diseased or blocked, robotic-assisted cholecystectomy can be used to remove the gallbladder.

3. Robotic Hernia Surgery

An incisional or ventral hernia occurs when part of an organ, usually the intestine, protrudes through a weakness in the abdominal wall caused by a previous incision. Robotic laparoscopic surgery can repair ventral and incisional hernias without open surgery, and significantly reduces the likelihood of hernia recurrence.
