Kocher figured out that by loosening it, the duodenum could be moved like it was in the early stages of development. [3] Kocher also knew that the duodenum and pancreas are initially hanging freely in the belly, connected by a mesentery. The Kocher maneuver brings these organs back to their original position in the belly.
Resection is sometimes a part of a treatment plan, [2] but duodenal cancer is difficult to remove surgically because of the area that it resides in—there are many blood vessels supplying the lower body. Chemotherapy is sometimes used to try to shrink the cancerous mass. Other times intestinal bypass surgery is tried to reroute the stomach to ...
Surgery may follow neoadjuvant chemotherapy, which aims to shrink the tumor and increase the likelihood of complete resection. [8] Post-operative death and complications associated with pancreaticoduodenectomy have become less common, with rates of post-operative mortality falling from 30 to 10% in the 1980s to less than 5% in the 2000s.
A bowel resection or enterectomy (enter-+ -ectomy) is a surgical procedure in which a part of an intestine (bowel) is removed, from either the small intestine or large intestine. Often the word enterectomy is reserved for the sense of small bowel resection, in distinction from colectomy , which covers the sense of large bowel resection.
Malignant cell growth, such as a pancreatic head tumor, [3] can prevent proper repositioning of the duodenum to be in close contact with the bile duct. [5] Performing a CDD may lead to a tension-filled surgical anastomosis, leading to bile leakage and jaundice. [6] There is also the possibility of active tumour growth obstructing the CBD.
Billroth I, more formally Billroth's operation I, is an operation in which the pylorus is removed and the distal stomach is anastomosed directly to the duodenum. [1] [2] The operation is most closely associated with Theodor Billroth, but was first described by Polish surgeon Ludwik Rydygier. [2] The surgical procedure is called a ...
The duodenal switch (DS) procedure, also known as a gastric reduction duodenal switch (GRDS), is a weight loss surgery procedure that is composed of a restrictive and a malabsorptive aspect. The restrictive portion of the surgery involves removing approximately 70% of the stomach (along the greater curvature) and most of the duodenum .
For severe duodenal ulcers, it may be necessary to remove the lower portion of the stomach and the upper portion of the small intestine. If there is a sufficient portion of the upper duodenum remaining, a Billroth I procedure is performed, where the remaining portion of the stomach is reattached to the duodenum before the common bile duct.
