Intestinal anastomosis - layers, nomenclature, phasis of healing, Lembert stitch, and Connell stitch
Hello, and welcome back to our channel where we talk about different medical procedures and surgical methods. Today we are going to dive deep into a crucial aspect of gastrointestinal surgery, intestinal anastomosis. Intestinal anastomosis is a surgical procedure that connects two parts of the intestine, allowing for the passage of food and other waste materials. In this video, we'll talk about the different types of anastomosis and the phases of healing after the operation. We'll also discuss the use of particular surgical suturing techniques, the Lembert stitch and the Connell stitch, and their benefits in gastrointestinal surgery.
There are different types of intestinal anastomosis, but the most common ones are end-to-end, side-to-side, and end-to-side. End-to-end anastomosis is the most widely used and involves connecting the cut ends of two intestine segments. The side-to-side anastomosis connects the side of one part to the side of another part, allowing a better flow of contents. End-to-side is a technique that involves connecting one end of a segment of the intestine to the side of another segment.
After an intestinal anastomosis has been performed, the healing process begins immediately. The healing process is divided into three phases: inflammatory, proliferative, and remodeling phase. During the inflammatory phase, the body's immune system responds to the surgical trauma, and the area becomes inflamed. The proliferative phase follows, where the body starts to produce new cells around the surgical area. Finally, the remodeling phase, where the body reorganizes the new tissues and regains the strength of the tissue.
The Lembert stitch is a type of suture used to join the intestine during anastomosis. It is named after French surgeon Xavier Lembert. The Lembert stitch is used to strengthen the intestinal wall, prevent leakage, and improve the blood supply in the joined intestine. It is a simple running stitch that penetrates the seromuscular layer of the intestine wall.
Connell stitch on the other hand is a special continuous suturing technique that is commonly used for the second and third layers of anastomosis
