Omentum and Small both have adhered to the anterior abdominal wall for which adhesiolysis was performed single-handed.

A hernia is the protrusion of tissue or part of an organ through the bone, muscular tissue, or the membrane by which it is normally contained. Hernias can be classified as internal or external and as abdominal or thoracic.

Abdominal wall hernias can occur spontaneously (presumably from congenital defects) or after surgery. When they occur after surgery, they are called incisional hernias, which can range from small defects to extremely large ones

Abdominal incisional hernia is a common complication after open abdominal operations. Laparoscopic procedures have obvious mini-invasive advantages for surgical treatment of abdominal incisional hernia, especially to cases with big hernia defect. Laparoscopic repair of incisional hernia has routine mode but the actual operations will be various according to the condition of every hernia. Key points of these operations include design of the position of trocars, closure of defects and fixation of meshes. The details of these issues and experiences of perioperative evaluation and treatment will be talked about in this article.

Laparoscopic surgery has revolutionized hernia repair by minimizing postoperative pain, reducing hospital stay, and accelerating recovery. Among various laparoscopic techniques, single instrument dissection for incisional hernia repair represents an innovative approach that simplifies the procedure while maintaining safety and efficacy.

Understanding Incisional Hernia

An incisional hernia occurs when abdominal contents protrude through a weakness at the site of a previous surgical incision. Patients often present with a visible bulge, discomfort, or pain, particularly when lifting heavy objects or during physical activity. Traditional open repair involves extensive dissection and larger incisions, leading to prolonged recovery and higher risk of wound complications.

Advantages of Laparoscopic Repair

Laparoscopic repair of incisional hernia has multiple benefits:

Smaller incisions → less postoperative pain and better cosmetic results

Reduced risk of wound infection

Quicker return to normal activity

Enhanced visualization of the abdominal wall and hernia defect

Single Instrument Dissection Technique

Traditionally, laparoscopic hernia repair requires multiple instruments for dissection, mesh placement, and suturing. Single instrument dissection streamlines this process. The key features of this technique include:

Minimal Instrumentation: Using one primary laparoscopic dissector or energy device, the surgeon can carefully separate adhesions, reduce the hernia sac, and prepare the defect for mesh placement.

Precision Dissection: Advanced laparoscopic instruments allow delicate tissue handling, reducing trauma to surrounding structures such as bowel loops and blood vessels.

Efficient Mesh Placement: Once the defect is prepared, a prosthetic mesh can be positioned and fixed using tacks, sutures, or adhesives, depending on the surgeon’s preference.

Reduced Operative Time: With fewer instruments to manage, the procedure becomes more streamlined, potentially shortening the duration of surgery.

Indications and Patient Selection

Single instrument dissection is suitable for:

Small to moderate-sized incisional hernias

Patients without dense adhesions or complex previous surgeries

Individuals seeking minimally invasive options with faster recovery

Patients with extremely large hernias or complicated abdominal histories may still require traditional multi-instrument laparoscopic repair or open surgery.

Outcomes and Safety

Studies and clinical experience indicate that single instrument laparoscopic repair is:

Safe and reproducible

Associated with lower postoperative pain

Comparable recurrence rates to conventional laparoscopic repair

Economical, as fewer instruments are required

Conclusion

Single instrument dissection in laparoscopic incisional hernia repair represents a significant step forward in minimally invasive surgery. By simplifying the procedure, minimizing trauma, and maintaining excellent outcomes, this technique offers surgeons a practical and effective alternative to traditional multi-instrument approaches. Continued research and refinement will further enhance its role in modern hernia surgery.
