Minimally invasive interventional treatment for pancreatic carcinoma induced intestinal obstruction
2021
Abstract Intestinal obstruction is one of the common complications of pancreatic cancer, which is closely related to the location of the tumor and the degree of metastasis. On the one hand, the tumor tissue invades the antrum, duodenum, jejunum, and transverse colon by partial infiltration and compression, leading to local intestinal stenosis and obstruction. On the other hand, it invades the reticular membrane by lymphatic and intraperitoneal sowing. The pelvic peritoneum leads to different degrees of stenosis and obstruction in the small intestine and colorectal lumen. Intestinal obstruction caused a sharp decline in the quality of life of patients, and the body rapidly depleted. The treatment of intestinal malignant stenosis has traditionally appealed to surgery, but for patients who are not suitable for surgery, actively adopt various antitumor treatments that are suitable for the specific situation of patients, and use catheter stent technology to clear the intestines. At present, the more mature stenting of gastric antrum, duodenal obstruction, and colorectal obstruction refers to the application of endoscopic or X-ray-guided interventional techniques to retrograde the metal stent into the gastric antrum through the oral cavity or anus. This chapter focuses on X-ray-guided internal stent placement.
