12 fat intestinal ectopic pancreatic symptoms?

summary

Ectopic pancreas is also called labyrinthine pancreas or accessory pancreas. Any isolated pancreatic tissue that grows outside the pancreas itself and has no anatomical or vascular connection with normal pancreatic tissue is called ectopic pancreas. It belongs to a congenital malformation. About 90% of the ectopic pancreas is located in the upper digestive tract, mainly in the stomach (usually located in the greater curvature within 5 cm from the pylorus), duodenum and jejunum. The common bile duct, duodenal papilla, liver, ileum, mesentery, greater omentum, lung, Meckel diverticulum, colon, appendix, diaphragm, lung and esophagus were rare sites. Most of them are single, and multiple cases are rare. 12 fat intestinal ectopic pancreatic symptoms? Let's talk about it.

12 fat intestinal ectopic pancreatic symptoms?

1. Obstructive ectopic pancreas growing in the digestive tract can cause the compression or stenosis of the organ, resulting in obstructive symptoms. Pyloric obstruction can be caused if it is located in the gastric antrum; Bile duct obstruction may occur in the ampulla of Vater; It can cause intestinal obstruction or intussusception.

2. Hemorrhagic ectopic pancreas is easy to cause gastrointestinal bleeding, which may be caused by congestion and erosion of gastrointestinal mucosa around ectopic pancreas, or invasion of gastrointestinal mucosal vessels.

3. Ulcerative ectopic pancreas located in gastrointestinal tract can secrete trypsin and form ulcer due to stimulation of digestive juice; The ectopic pancreas located under the mucosa can compress the upper mucosa, cause mucosal atrophy, and then ulceration.

matters needing attention

Surgical treatment should be performed when the secondary pathological changes of ectopic pancreas cause obvious symptoms. Such as subtotal gastrectomy, intestinal resection, diverticulectomy, etc. If the lesion is small, partial resection of gastric wall or intestinal wall can be performed, and then the gastric wall or intestinal tube can be sutured. Endoscopic endarterectomy (ESD) is not a routine procedure for simple dissection of ectopic pancreatic tissue from the stomach and intestinal wall. If ectopic pancreas is occasionally found in other operations, and the patient has no symptoms caused by ectopic pancreas before operation, it should be removed at the same time as far as possible without affecting the original operation and it is not difficult to remove the ectopic pancreas. Frozen section should be made during operation. If there is canceration, the scope of resection should be expanded or radical operation should be performed.
