Abstract:

Pancreaticoduodenectomy (PD) has become the standard treatment for malignant tumors of the periampullary malignancies, and some benign pancreatic diseases and pancreatic injuries. Due to the large number of digestive organs involved in the surgery and the complexity of the operation, there are many postoperative complications, among which gastric emptying disorder is one of the most common complications after PD surgery. At present, the etiology and pathogenesis of gastric emptying disorders have not been fully elucidated. Some studies suggest that gastric emptying disorders after PD surgery may be related to the individual condition of the patient before surgery and surgical methods such as retaining or not retaining pyloric PD and gastrojejunostomy. Non surgical treatment is still the main treatment for gastric emptying disorders. Most of the patients recovered after receiving conservative treatment such as nutritional support treatment, gastrointestinal decompression， gastroprokinetic agent, acupuncture and moxibustion, gastric electrical stimulation, etc. This article mainly discusses the related factors of gastric emptying disorder after pancreatoduodenectomy and provide theoretical basis for prevention and treatment of gastric emptying disorder.
