Introduction:

Temporary abdominal closure (TAC) refers to the techniques employed to provide temporary closure and support to the abdominal wall in situations where primary closure is not feasible or advisable. This comprehensive article aims to provide a deeper understanding of temporary abdominal closure techniques, including their indications, methods, and considerations. By gaining insights into TAC approaches, healthcare professionals can make informed decisions regarding the management of complex abdominal conditions and optimize patient outcomes.

Indications for Temporary Abdominal Closure:

Temporary abdominal closure techniques may be utilized in various clinical scenarios, including:

• Abdominal compartment syndrome (ACS): In cases of ACS, where increased intra-abdominal pressure compromises organ perfusion and function, TAC helps control intra-abdominal pressure and mitigate the effects of abdominal hypertension.
• Open abdomen: An open abdomen refers to a situation where the abdominal cavity is intentionally left open, often due to the need for repeated surgical interventions or to manage intra-abdominal infections or complications.
• Trauma or emergency surgeries: In cases of severe trauma or emergency surgeries, TAC may be employed when primary abdominal closure is not possible due to tissue loss, edema, contamination, or compromised wound healing.

Temporary Abdominal Closure Techniques:

Several techniques are commonly employed for temporary abdominal closure, including:

• Bogota bag or silo: This technique involves placing a large sterile plastic bag or sterile surgical drapes over the exposed abdominal contents and securing it with a suture or adhesive. The bag is gradually reduced in size over time as edema subsides, allowing for eventual primary closure.
• Negative pressure wound therapy (NPWT): NPWT utilizes a vacuum-sealed dressing applied to the open abdomen, which creates negative pressure and promotes wound healing by facilitating drainage, reducing edema, and promoting granulation tissue formation.
• Mesh or synthetic grafts: Mesh or synthetic grafts can be used to bridge the abdominal defect and provide mechanical support while preventing visceral adhesions. They may be combined with NPWT or other techniques for improved outcomes.
• Dynamic or adjustable closure devices: Dynamic closure devices, such as the Barker's vacuum pack or the Wittmann Patch, allow for customizable and adjustable closure, accommodating changes in abdominal volume and reducing the risk of fascial retraction.

Considerations for Temporary Abdominal Closure:

When implementing TAC techniques, healthcare professionals must consider the following:

• Timing of closure: The optimal timing for definitive abdominal closure should be assessed individually based on the patient's condition, intra-abdominal pressure, and the presence of any underlying infection or complications.
• Infection control: Strict aseptic techniques, appropriate antimicrobial therapy, and regular monitoring of the open abdomen are crucial to prevent or manage infections and reduce the risk of complications.
• Monitoring and management of intra-abdominal pressure: Regular measurement and monitoring of intra-abdominal pressure are essential to guide therapeutic interventions and prevent or manage complications related to abdominal hypertension.
• Nutritional support: Adequate nutritional support is vital to support wound healing, minimize catabolism, and optimize patient outcomes. Enteral or parenteral nutrition may be necessary in patients with open abdomens.

Conclusion:

Temporary abdominal closure techniques play a critical role in managing complex abdominal conditions when primary closure is not feasible or advisable. By understanding the indications, techniques, and considerations for temporary abdominal closure, healthcare professionals can make informed decisions and provide optimal care to patients. Individualized management, close monitoring, and timely intervention are key to achieving successful abdominal wall closure and promoting patient recovery.
