Minimally Invasive Pancreatic Surgery

The introduction of Minimally Invasive Pancreatic Surgery has revolutionised the surgical management of pancreatic cancer. Generally, pancreatic surgeries consist of large incisions and a long post-operative recovery due to the organ's deep and complex location. Surgeons can now perform these complex resections with laparoscopic and robotic-assisted techniques through a few tiny incisions. This approach focuses on accuracy while causes less physical trauma to the body.

This article will cover the types of minimally invasive procedures performed, the advanced technology that enables these procedures and their unique benefits with respect to recovery and long-term results. At Gleneagles Hospitals, these advanced methods will be used as a core component of a patient-centred strategy to combat pancreatic disease in the optimised treatment approach.

The pancreas is one of the most complex organs to operate on due to its position behind the stomach and its proximity to major blood vessels, the spleen, and the small intestine. Open surgery was the only definite technique to achieve complete tumour removal, and it had been used for decades.

This has changed significantly with the advent of minimally invasive techniques. Surgeons can now navigate the limited spaces of the abdomen with as much control and clarity as with high-definition cameras and specialised surgical instruments, achieving outcomes comparable to traditional open surgery in carefully selected patients. These modern methods allow for the same thoroughness as open surgery but with much less physical impact on the body.

Surgeons typically categorise minimally invasive pancreatic surgery based on the tumour's location and the specific technique used.

1. Laparoscopic Pancreatic Surgery

A laparoscopic surgery involves a few small holes, commonly referred to as ports, made by the surgeon. A laparoscope is a thin tube with a camera that provides a live video feed to a monitor in the operating room. Then the surgeon uses long, thin instruments to perform the surgery. This technique is very useful in distal pancreatectomies, in which the tail or body of the pancreas is excised.

2. Robotic-Assisted Pancreatic Surgery

Robotic surgery is an advanced type of minimally invasive surgery. The surgeon sits at a console and operates robot arms which carry the surgical tools.

• 3D Vision: The robotic system allows a surgeon to observe the operating area in three dimensions, enlarged, enabling the surgeon to examine nerves and arteries in minute detail.
• Wristed Instruments: Robotic tools provide enhanced range of motion, allowing more flexibility than the human wrist or traditional laparoscopic instruments. This is very useful for suturing a difficult Whipple surgery.

Surgery is also necessary in the treatment of pancreatic cancer, especially if the tumour is confined and has not spread extensively. In certain cases, minimally invasive pancreatic surgery is used to safely remove the cancer using these procedures. The treatment is based on factors: size, location, and stage of the cancer.

Common procedures include:

• Distal pancreatectomy: This surgery entails the excision of the body and tail of the pancreas.
• Pancreaticoduodenectomy (Whipple procedure): This is a surgical procedure that involves removing the head of the pancreas, along with parts of the bile duct, small intestine, and sometimes the stomach.
• Total pancreatectomy: Removal of the entire pancreas in specific cases

Minimally invasive techniques are more commonly used for distal pancreatic resections, although robotic systems have expanded the feasibility of performing complex procedures, such as the Whipple procedure, in selected patients. The ultimate goal is the elimination of the cancer with clean margins and lowering the risk to the patient.

Successful outcomes depend on careful planning and the use of built-in medical technology.

Pre-Surgical Mapping

Before surgery, a surgical team uses cutting-edge imaging, such as 3D CT reconstructions, to map the patient's interior organs. This allows the surgeon to plan the safest surgical approach while avoiding major blood vessels, yet removing the cancer completely.

During the Surgery

The patient is placed under general anaesthesia for the surgery.

• Access: The surgeon places the ports and inflates the abdomen with carbon dioxide to create a clear working space.
• Dissection: The surgeon carefully removes the damaged section of the pancreas from the surrounding organs and blood supply.
• Removal: The tissue can be removed using one of the slightly enlarged port sites in a small surgical bag.
• Reconstruction: If part of the digestive tract was removed, the surgeon would reconstruct the connections using fine sutures or staples.

There are several significant benefits associated with a minimally invasive approach, which lead to an improved experience overall:

• Less Post-Operative Pain: A small incision causes significantly less damage to the abdominal wall and muscles, minimising the need for strong painkillers.
• Reduced Blood Loss: The enhanced magnification enables precise control of blood vessels, resulting in minimal blood loss during the procedure.
• Lower Risk of Infection: Smaller wounds are easier to keep clean and heal much faster than large open wounds.
• Quick Recovery: The patients tend to spend less time in the hospital and return to a normal diet and daily activities.

Minimally invasive surgery cannot be done for all patients with pancreatic cancer. There are multiple considerations made by doctors before recommending this method:

• Size and location of the tumour
• Involvement of adjacent blood vessels.
• Stage of cancer
• General medical fitness and health condition.
   

Minimally invasive procedures are more likely to be suitable for patients with early-stage pancreatic cancer and those with tumours that are accessible. Each case is assessed by a multidisciplinary team of surgeons, oncologists, and radiologists to determine the most appropriate treatment plan.

The Gleneagles Hospitals offer a specialised pancreatic care unit that offers a specialised environment that consists of:

• Advanced Robotic Platforms: Access to the most advanced robotic surgical machines capable of performing highly precise procedures in the human body.
• Specialised Surgical Teams: Experienced laparoscopic and robotic surgeons with extensive training and expertise in pancreatic excision.
• Comprehensive Oncology Support: This is a multidisciplinary team that combines surgery with other treatments like chemotherapy or radiation.
• Specialised Nursing Care: Nurses who have received particular training to care for pancreatic patients following surgery.
