The tissue removed during a pancreaticoduodenectomy Whipple surgery. The most common technique of a pancreaticoduodenectomy consists of the en bloc removal of the distal segment (antrum) of the stomach, the first and second portions of the duodenum, the head of the pancreas, the common bile duct, and the gallbladder.
For this purpose, the stomach is removed as previously described; the dissected stomach lumen is then anastomosed onto the front wall of the duodenum. [ 9 ] Usually, an oblique incision should be made on the duodenal front wall so that the incision level starts from oral–medial and goes to aboral–lateral. [ 9 ]
The small intestine is involved in both the absorption and digestion of nutrients, whereas the large intestine is responsible for the elimination of wastes . The small intestine consists of 3 parts: duodenum, jejunum and ileum. [3] The duodenum is the first part of the small intestine and is connected to the stomach via the pyloric valve. The ...
Cancerous tumours arising from the CBD, the ampulla, or the portion of the duodenum near the ampulla can result in distal CBD obstruction. When the masses are incapable of being surgically removed, CDD can be performed. In some cases where the growing tumour occludes the new pathway, CDD will only provide palliative relief.
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.
The operation can sometimes be performed at the same time as a partial gastrectomy (the removal of part of the stomach). Gastroenterostomy was in the past typically performed to treat peptic ulcers , but today it is usually carried out to enable food to pass directly to the middle section of the small intestine when it is necessary to bypass ...

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.
