It is named after Dr. Dennis Connell, who described the technique in 1962. The Connell suture is specifically designed to evert the edges of the tissue being sutured, which can be particularly useful in areas where wound closure under tension is necessary or where maintaining luminal integrity is important.
Here's how the Connell suture technique is typically performed:
Placement of the first bite: The needle is inserted through one edge of the tissue to be sutured, such as the mucosa of the gastrointestinal tract or the bladder wall. It enters perpendicular to the tissue surface and exits on the opposite side, typically at a distance from the wound edge.
Formation of a loop: After exiting the tissue, the needle is re-inserted into the same edge of the tissue, but instead of exiting on the opposite side, it is passed through the loop formed by the suture material, creating a looped configuration.
Tightening: The suture is then tightened, causing the tissue edges to evert or flip outward. This eversion helps to ensure proper apposition of the tissue edges and reduces the risk of luminal narrowing or stricture formation.
Repeating the process: The process is repeated along the length of the wound, with each bite taken in a similar manner to the previous one, creating a continuous row of everted sutures.
Knotting: Once the desired length of the wound has been sutured, the ends of the suture material are tied securely to complete the closure.
The Connell suture technique is particularly useful in procedures involving hollow organs or tubular structures, where maintaining luminal patency is important. By everting the tissue edges, it helps to prevent inversion of the tissue into the lumen, reducing the risk of strictures or obstruction. Additionally, the everted edges provide better wound healing and reduce the likelihood of tissue ischemia or necrosis.
