A surgical anastomosis is an artificial connection made by a surgeon to link two structures together. This procedure may be necessary when an artery, vein, or part of the intestine is blocked. The surgeon removes the blocked portion in a procedure called resection. The two remaining ends are then joined together, or anastomosed, and are sewn or stapled to restore continuity.
Antrectomy, also known as distal gastrectomy, is a surgical procedure that involves the removal of the lower 30% of the stomach, known as the antrum. This type of surgery is a form of partial gastrectomy, meaning only a portion of the stomach is removed, rather than the entire organ. Distal gastrectomy is commonly performed to treat stomach cancer and other conditions affecting the lower part of the stomach.
In general surgery, a Roux-en-Y anastomosis, commonly referred to as Roux-en-Y, is a type of surgical connection (anastomosis) that joins the end of one section of the bowel to the side of another section. This technique is used to reconstruct the gastrointestinal tract. Typically, this procedure involves connecting the stomach to a part of the small intestine that is further down the gastrointestinal tract, beyond the cut end. This method is often employed to ensure proper digestive function after sections of the stomach or intestine have been removed.
Surgery is the most common treatment for colorectal cancer. It can range from minimally invasive procedures, such as removing a polyp during a colonoscopy, to more extensive operations, such as removing the entire colon in rare cases. Many colorectal cancer surgeries involve removing the tumor, the section of the colon where the tumor was found, surrounding normal tissue, and nearby lymph nodes. This comprehensive approach helps ensure that all cancerous cells are removed and reduces the risk of recurrence
