The 5-year postoperative survival rate for duodenal adenocarcinoma is about 50%.
Among all small bowel tumors, adenocarcinoma accounts for about half of them, among which duodenal adenocarcinoma is the most common.
Clinical manifestations of duodenal adenocarcinoma include abdominal pain, weight loss, nausea and vomiting, etc. Anemia with intermittent jaundice is often indicative of duodenal cancer. The treatment is mainly surgical, and the survival rate is about 50% in 5 years after surgery.
Surgery for duodenal adenocarcinoma is pancreaticoduodenectomy, which needs to remove all the invaded tissues, and the distal and proximal ends of the resection need to be more than 10cm away from the edge of the lesion. If the extent of tumor invasion is relatively large, short-circuit anastomosis or biliary bypass surgery can be chosen to relieve the obstruction.
After duodenal adenocarcinoma surgery, the prognosis varies among different people due to various factors such as physical condition, prognosis of recovery, etc. The earlier the treatment, the better the prognosis.
