Czerny intestinal suture is a surgical technique for creating an anastomosis between the two ends of a damaged section of the intestine during the process of its repair. This method was developed by the German surgeon Christian Czerny in 1838 and is one of the most common methods of connecting damaged areas of the intestine. Czerny was highly respected among his colleagues for his achievements in the field of medicine. He also made significant contributions to the development of medical theory and practice. Today, after several decades, the Cherny intestinal suture remains a reliable method of connecting damaged parts of the intestine, especially when the patient has a difficult time going through this intervention. To better understand how this method works, let's look at the anatomical structure of the intestine and its function. The intestine is the main human digestive tube, which begins in the stomach and ends in the rectum. There is no feces from the intestinal lumen, but the intestinal canal in a living person is very often damaged due to severe abdominal surgery. Therefore, after complex interventions, intestinal restoration becomes one of the priorities. Anatomically, the intestine consists of many segments with different functions. However, there is often a need to restore the continuity of the intestinal mucosa between two damaged areas. In this case, surgeons resort to a method called “black intestinal suture”. This method uses a special needle-and-thread tool, also known as an intestinal needle. This technique involves inserting a needle and thread through both sides of the affected area and pulling the thread through both ends of the piece of intestine being sutured. This allows you to create an anastomosis or, more simply, sew the ends together. When restoring the mucous membrane and performing an intestinal suture, the following points must be taken into account: 1. Maintain parallelism of the damaged surfaces of the intestines connected to each other. Otherwise, the tissue structure of the intestine may be disrupted, which will lead to obstruction or other dangerous consequences. 2. Consider the location of the muscular layers of the intestinal wall. If we advance the thread in front of the muscle membrane, then the resulting scar may turn out to be a weak area where it can be destroyed due to stretching of the organ. To avoid this, it is necessary to correctly distribute the direction of tension of the connective tissue. 3. Create an additional scar at the cross-section of the threads. An intestinal suture made incorrectly can lead to intussusception, and such a scar will separate the connecting areas and prevent the destruction of the restorative Thus, black intestinal sutures are used in various medical fields and in many operations on the abdominal cavity to create a reliable connection between various structures and tissues. They continue to be used successfully in modern medicine and remain essential to ensure safe and successful treatment.
