What technique is ideal for suturing a perforated ulcer during surgery?

The purse string suture technique is ideal for suturing a perforated ulcer during surgery due to its ability to effectively close the defect while minimizing tension on the surrounding tissue. This technique is particularly advantageous when dealing with circular or oval defects, which are common in perforated ulcers.

By encircling the defect with the suture and then tightening it to bring the edges together, the purse string suture allows for a secure closure that reduces the risk of leakage and promotes healing. Additionally, this method is useful in situations where the surrounding tissue may be fragile or when there is a need for a quick closure to minimize contamination from the abdominal cavity.

In contrast, the other techniques, such as overlapping sutures or continuous horizontal mattress sutures, are generally not as effective in addressing the specific challenges posed by a perforated ulcer, where a more tailored approach like the purse string suture can provide both security and tissue preservation. Simple continuous sutures, while straightforward, might not offer the same degree of tension distribution and sealing needed in these cases.
