Robotic surgery

Introduction

Dr. Srinivas Bojanapu, a highly acclaimed expert in Gastrointestinal and General Surgery with over 20 years of experience, is at the forefront of robotic liver transplantation. This cutting-edge approach is transforming the landscape of liver transplants by offering a sophisticated alternative to traditional open donor surgery. With the precision, dexterity, and enhanced visualization provided by robotic systems, Dr. Bojanapu can perform liver transplants with remarkable efficiency and minimal patient discomfort.

Rising Need for Liver Transplants

The incidence of liver diseases such as cirrhosis is increasing due to lifestyle factors like obesity, diabetes, non-alcoholic fatty liver disease, and excessive alcohol consumption. As liver damage progresses to liver failure—whether acute or chronic—liver transplantation becomes the only viable option to save a patient's life. Common causes of liver damage include viral hepatitis (A, B, C), alcoholic liver disease, genetic disorders like hemochromatosis and Wilson’s disease, biliary duct conditions, primary sclerosing cholangitis, liver cancer, and drug-induced damage. For patients whose liver damage is beyond repair, transplantation is the final recourse.

Liver Transplant Techniques

Deceased Donor Liver Transplant (DDLT): This involves harvesting a healthy liver from a brain-dead donor. Due to cultural and social factors, this type of transplant is not common, accounting for only 7-8% of cases in certain regions.

Live Donor Liver Transplant (LDLT): The liver's unique ability to regenerate allows a healthy person to donate a portion of their liver. The donated segment grows to full size in both the donor and recipient within a few months, making LDLT a viable and preferred option.

Robotic vs. Open Hepatectomy

In the past, open donor liver surgery was the standard approach, but it came with several drawbacks: increased postoperative pain, higher infection risk, longer recovery time, visible scarring, and extended hospital stays. Laparoscopic transplants, which involve minimally invasive techniques, were introduced to overcome some limitations of open surgery, but these also have drawbacks such as limited range of motion, challenging ergonomics, and longer learning curves for surgeons.

Advantages of Robotic Surgery

Dr. Srinivas Bojanapu utilizes state-of-the-art robotic systems, which offer significant benefits over both open and laparoscopic techniques:

• Precise Control and Dexterity: The robotic arms translate the surgeon's hand movements into precise actions at the surgical site, ensuring stability and control without any loss of accuracy.
• Superior 3D Visualization: High-resolution 3D imaging provides clear and stable views of the surgical field, allowing the surgeon to make more informed decisions during the procedure.
• Endo-Wrist Technology: The robotic arm's Endo-Wrist provides a 360-degree range of motion, enabling intricate maneuvers that are difficult to achieve with conventional instruments.
• Tremor Elimination: Robotic systems filter out any hand tremors, allowing for steadier movements during surgery.
• Ergonomics and Comfort: The surgeon operates from a console in a comfortable seated position, reducing fatigue during lengthy procedures.
• Potential for Remote Surgery: The robotic system enables the possibility of performing surgery from a remote location, broadening access to specialized care.

Procedure Overview

The process begins with thorough preparation for both the donor and recipient. The surgery is performed under general anesthesia, with the robotic arms inserted through small incisions to perform the necessary surgical steps. These include disconnecting the bile ducts, hepatic artery, and portal vein from the diseased liver, removing it, and transplanting the new liver segment. Once in place, the bile ducts and blood vessels are reconnected, and the incision is closed.

Postoperative Care and Recovery

Patients who undergo robotic liver transplantation generally experience faster recovery, reduced pain, and shorter hospital stays. Dr. Bojanapu ensures that patients receive comprehensive postoperative care, including guidelines for a swift and safe recovery.

The Future of Robotic Liver Transplants

Robotic liver transplantation is poised to become the standard in the future, with emerging advancements in artificial intelligence, machine learning, and bioengineered livers potentially enhancing outcomes. Dr. Bojanapu's pioneering work in this field is paving the way for more efficient, safer, and less invasive liver transplantation procedures.
