Severe abdominal adhesions are fibrous bands that form between organs and tissues within the abdominal cavity, often as a result of previous surgeries, infections, inflammation, or trauma. These adhesions can cause chronic abdominal pain, intestinal obstruction, infertility, and complicate future surgeries. Traditional open surgery for severe adhesions carries significant risks, including inadvertent injury to the bowel, blood vessels, or other organs, and often leads to the formation of new adhesions.

The advent of Da Vinci robotic surgery has transformed the management of complex abdominal adhesions. With enhanced precision, superior visualization, and advanced instrument dexterity, robotic surgery allows surgeons to perform safe, meticulous adhesiolysis even in cases where conventional laparoscopy or open surgery would be highly challenging. Dr. R. K. Mishra, a globally recognized expert in minimally invasive and robotic surgery, has pioneered robotic techniques for the safe management of severe abdominal adhesions.

Causes and Consequences of Severe Abdominal Adhesions

Abdominal adhesions are a natural response to tissue injury, but in some cases, they become dense, vascular, and fibrotic, creating significant surgical challenges. Common causes include:

Previous abdominal or pelvic surgeries, particularly multiple laparotomies

Peritonitis or intra-abdominal infections

Endometriosis and chronic pelvic inflammation

Trauma or injury to abdominal organs

Foreign materials such as sutures or talc from gloves

The consequences of severe adhesions can be profound:

Intestinal obstruction – adhesions are a leading cause of small bowel obstruction

Chronic abdominal or pelvic pain – due to restricted organ mobility

Infertility – adhesions affecting fallopian tubes or reproductive organs

Complicated reoperations – dense adhesions increase the risk of intraoperative injuries

Advantages of Da Vinci Robotic Surgery

Robotic surgery offers several unique advantages over traditional open or laparoscopic surgery in the management of severe adhesions:

Enhanced Visualization – The robotic system provides a 3D, high-definition view of the abdominal cavity, allowing precise identification of adhesion planes.

Superior Dexterity – Articulating instruments mimic the human wrist with seven degrees of freedom, enabling delicate dissection in confined spaces.

Reduced Risk of Organ Injury – Fine instrument control and magnified visualization minimize inadvertent damage to bowel, bladder, ureters, and major blood vessels.

Minimally Invasive Approach – Smaller incisions lead to reduced postoperative pain, faster recovery, and lower infection risk.

Ergonomic Comfort for Surgeons – Surgeons can operate from a console, reducing fatigue during complex and prolonged adhesiolysis procedures.

Surgical Technique: Step by Step
Patient Preparation and Positioning

The patient is placed under general anesthesia in the supine or lithotomy position, depending on the location of adhesions. Proper positioning facilitates optimal exposure of the abdomen and pelvis.

Port Placement and Docking

Small incisions (5–12 mm) are created for the robotic trocars. The camera port is usually placed near the umbilicus, while other ports accommodate robotic arms and assistant instruments. The Da Vinci robot is docked carefully to ensure instrument mobility without clashing.

Systematic Exploration

The surgeon performs a thorough inspection of the abdominal cavity using the robotic camera. Dense adhesions are carefully identified, noting their location, vascularity, and involvement of organs.

Adhesiolysis

Robotic instruments allow meticulous dissection of adhesions:

Sharp dissection is preferred for dense fibrous bands

Blunt dissection is used for loose adhesions

Energy devices like bipolar cautery or ultrasonic shears may be employed to achieve hemostasis while minimizing thermal injury

Surgeons maintain constant awareness of underlying bowel, ureters, and vessels to prevent inadvertent injury

Restoration of Anatomy

Once adhesions are lysed, organs are carefully repositioned in their normal anatomical locations. The surgeon ensures that tissue planes are free and mobile, reducing the risk of recurrence.

Hemostasis and Closure

After completing adhesiolysis, the robotic instruments are used to achieve meticulous hemostasis. Ports are removed, and small incisions are closed with absorbable sutures, leaving minimal scarring.

Adhesion Prevention Strategies

Dr. R. K. Mishra emphasizes that prevention of new adhesions is as important as their removal. Strategies include:

Gentle tissue handling to minimize trauma

Meticulous hemostasis to reduce fibrin deposition

Use of adhesion barriers such as hyaluronic acid-carboxymethylcellulose membranes

Minimizing foreign body exposure from sutures or gloves

Laparoscopic or robotic approach to reduce peritoneal desiccation

Outcomes and Benefits

Reduced Postoperative Pain – Smaller incisions and minimal tissue trauma

Faster Recovery – Patients can often resume normal activities sooner than with open surgery

Lower Complication Rates – Precise robotic dissection minimizes inadvertent injury

Preservation of Organ Function – Especially important in reproductive-age women

Reduced Recurrence – Meticulous technique and adhesion prevention strategies help prevent future adhesion formation

Conclusion

Da Vinci robotic surgery has revolutionized the management of severe abdominal adhesions by combining minimally invasive techniques with unmatched precision and control. Surgeons like Dr. R. K. Mishra demonstrate that even dense, complex adhesions can be safely lysed, restoring organ function and reducing patient morbidity.

By integrating advanced surgical technology with meticulous technique and adhesion prevention strategies, robotic adhesiolysis provides patients with safer outcomes, faster recovery, and improved quality of life, establishing a new standard for complex abdominal surgery.
