How to Prevent Adhesions After Abdominal Surgery

Abdominal adhesions are a form of internal scar tissue that develops following surgical trauma, acting like fibrous bridges that connect organs or tissues that should remain separate. These pathological connections are a very common consequence of abdominal and pelvic procedures, occurring in a vast majority of patients who undergo open surgery. While many people remain asymptomatic, these internal scars can lead to serious health issues, including chronic abdominal pain and small bowel obstruction. Modern medicine has developed several strategies to interrupt this healing process and prevent the unwanted binding of internal structures.

Surgical Techniques to Minimize Tissue Trauma

The surgeon’s approach and meticulous care during the operation represent the first and most direct line of defense against adhesion formation. Since tissue injury triggers the inflammatory response that starts the scarring process, minimizing trauma to the delicate lining of the abdominal cavity is paramount. Minimally invasive approaches, such as laparoscopic surgery, use smaller incisions and cause less tissue manipulation than traditional open procedures, which often results in a reduced incidence of adhesion formation.

Gentle handling of the tissues is a fundamental principle, requiring surgeons to avoid excessive pulling, crushing, or drying out of the internal organs during the procedure. The presence of blood is highly inflammatory and acts as a biological glue that promotes scar tissue formation, making meticulous hemostasis, or the control of bleeding, necessary. Surgeons must also avoid introducing foreign materials into the abdomen, such as the starch powder found on some surgical gloves, which can provoke an intense inflammatory reaction.

At the conclusion of the operation, the surgical site is thoroughly irrigated with a warm saline solution to wash away any remaining blood clots, fibrin, or debris that could act as a scaffold for adhesion development. The choice of surgical instruments also plays a role, with energy devices like bipolar electrocautery or ultrasonic scalpels causing less thermal injury compared to older monopolar methods. These combined efforts reduce the overall inflammatory signal, lowering the likelihood that the body’s repair mechanism will result in internal binding.

Utilizing Specialized Physical Barriers

Beyond the precision of surgical technique, a second strategy involves placing specific materials designed to physically separate healing tissues during the initial, most vulnerable phase of recovery. These specialized physical barriers are placed over the injured sites at the end of the procedure to keep adjacent surfaces apart while the tissue regenerates. The goal is to provide a temporary shield that lasts long enough for the initial inflammatory period to pass, typically around five to seven days.

These barriers come in various forms, including thin films, sheets, gels, or viscous solutions, and are designed to be biocompatible and absorbed safely by the body over time. One common type is a film made of oxidized regenerated cellulose, which serves as a temporary partition on the injured tissue surfaces. Another type is a hyaluronate carboxymethylcellulose sheet that provides physical separation and is absorbed within days to weeks.

Liquid-based barriers, such as solutions containing icodextrin, are also used, particularly in minimally invasive procedures where they can be instilled to coat the abdominal surfaces. Regardless of the material, the function remains the same: to create a space between the injured peritoneal surface and a neighboring organ, preventing them from fusing together as the initial healing occurs. These products complement the meticulous surgical techniques used to prevent initial tissue trauma.

Post-Operative Recovery Strategies

While the surgical team employs techniques and materials during the procedure, the patient’s actions following surgery are the final layer of prevention. The most effective post-operative strategy the patient controls is early and progressive mobilization, meaning beginning to walk and move gently as soon as the medical team permits. Gentle movement encourages the natural gliding motion between internal organs, which can mechanically disrupt the early fibrin strands that form the basis of an adhesion.

Remaining stationary for extended periods allows injured tissues to rest in contact, providing conditions for initial fibrous connections to mature into permanent adhesions. Therefore, focusing on gradual increases in activity, like short, frequent walks, helps ensure that healing surfaces do not remain static and stuck together. This movement is a gentle encouragement of normal abdominal function and organ mobility.

Maintaining adequate hydration is also supportive of the healing process, as it helps maintain the natural fluid balance within the abdominal cavity, which is necessary for the proper function of the peritoneal lining. In some cases, patients may benefit from specific physical therapy, which can involve techniques aimed at promoting normal organ movement and enhancing blood flow to the recovering areas. By embracing early mobilization, the patient plays a direct and significant role in preventing the internal binding of tissues after an abdominal procedure.
