What is the surgical procedure called that involves connecting segments of the jejunum?

The surgical procedure that involves connecting segments of the jejunum is known as a jejunojejunostomy. This procedure is performed to bypass a section of the jejunum or to create an anastomosis (connection) between two segments of the jejunum in cases where a portion may have been resected due to disease or obstruction.

The jejunojejunostomy can be important in various surgical contexts, such as after a partial small bowel resection. It maintains continuity of the gastrointestinal tract and allows for normal digestive function by providing a pathway for the passage of intestinal contents.

Understanding the distinction between jejunojejunostomy and other procedures is critical. For example, esophagoduodenostomy involves the connection of the esophagus to the duodenum, which is entirely different from connecting segments of the jejunum. Vagotomy is a procedure involving the cutting of the vagus nerve, often done to reduce acid secretion in peptic ulcer disease, and pyloroplasty is a procedure that involves enlarging the pylorus to facilitate gastric drainage without creating jejunal connections. Thus, recognizing the specificity of jejunojejunostomy as the procedure focusing on the jejunum is essential.
