Final answer:
The abdominal wall after open surgery for rectal cancer is typically closed using a layered suturing technique that includes closing the peritoneum, fascia, and skin to minimize the risk of complications.
Step-by-step explanation:
The most appropriate method for closure of the abdominal wall after a low anterior resection for rectal cancer performed as open surgery is typically by suturing the muscular and fascial layers in a method that provides strong closure and minimizes the risk of complications such as infection or hernia. In many cases, the method of choice involves a layered closure, where each layer of the abdominal wall is reapproximated and sutured sequentially. This includes the peritoneum, the fascia, and the skin.
One common technique for the fascial layer is the use of non-absorbable or slowly absorbable sutures to close the incision in a continuous or interrupted pattern. After the fascia is closed, the subcutaneous tissue may be approximated, and finally, the skin can be closed with sutures or staples. In some instances, surgical mesh may be used to reinforce the closure, especially if the patient is at a higher risk for developing an incisional hernia.
