Pancreatic resection surgery is a surgical procedure used to remove part or all of the pancreas to treat related diseases or prevent disease progression. This surgery is primarily indicated for pancreatic malignant tumors, severe injuries, or chronic inflammation, aiming to improve patient prognosis by precisely excising diseased tissue.
The surgical methods vary based on the extent of resection, including total pancreatectomy, pancreaticoduodenectomy, and others, selected according to the location of the lesion and the patient's overall health. Modern techniques often incorporate laparoscopic or robotic-assisted surgery to reduce trauma and accelerate recovery.
Pancreatic resection can be classified into "Head of pancreas resection" and "Body and tail resection." The former targets lesions in the pancreatic head and involves removal of part of the duodenum and bile duct; the latter targets mid to posterior lesions and may preserve some pancreatic function. The mechanism focuses on completely removing diseased tissue to prevent cancer cell spread or organ failure caused by chronic inflammation.
In robotic-assisted surgeries, surgeons operate precise instruments through minimally invasive incisions, reducing tissue damage and improving suturing accuracy. After total pancreatectomy, patients require lifelong insulin and digestive enzyme supplementation due to complete loss of pancreatic function.
Main indications include pancreatic cancer, intraductal papillary mucinous neoplasm, and malignant transformation of pancreatic cysts. Surgery is also necessary for recurrent acute pancreatitis or severe trauma leading to pancreatic rupture.
Additionally, genetic pancreatic diseases such as hereditary pancreatitis, or cases where the lesion has invaded surrounding blood vessels and organs, may warrant extended resection to ensure complete treatment.
The procedure requires general anesthesia and is performed in an operating room, with duration ranging from 6 to 12 hours depending on the extent of resection. Preoperative imaging and biochemical tests are necessary to evaluate lesion location and patient metabolic status. Total pancreatectomy requires postoperative nutritional support planning.
Pancreaticoduodenectomy involves reconstructing the digestive tract, including suturing the pancreas, bile duct, and intestines. This step demands high precision to avoid anastomotic leaks and other complications. Postoperative hospitalization typically lasts 7-14 days, adjusted according to recovery progress.
Main advantages include:
Compared to conservative treatments, surgery directly removes diseased tissue, preventing metastasis of malignant tumors. For pancreatic trauma patients, surgery can immediately stop bleeding and prevent infection spread.
Common short-term risks include:
Long-term risks include diabetes mellitus, malabsorption, and nutritional deficiencies. Severe complications such as anastomotic leaks may lead to sepsis, requiring emergency reoperation.
Preoperative assessment of cardiac, pulmonary, and metabolic functions is essential. Patients with severe coagulopathy or systemic failure are contraindicated. Diabetic patients must have strict blood glucose control to reduce infection risk.
Contraindications include:
Pancreatic resection is often combined with chemotherapy or radiotherapy, such as adjuvant chemotherapy to eliminate microscopic lesions. Postoperative oral medications are temporarily halted, replaced with parenteral nutrition support.
Patients who have undergone radiation therapy may have increased tissue fibrosis, complicating surgery. Surgeons need to adjust suturing techniques to reduce complication risks.
Pancreaticoduodenectomy for early pancreatic cancer can achieve a 5-year survival rate of 20-30%, while for locally advanced tumors, it is about 5-10%. Clinical studies show that robotic-assisted surgery reduces complication rates by 30% compared to traditional open surgery.
For pancreatic cysts, surgical removal has a recurrence rate below 5%, indicating high curative potential. However, total pancreatectomy results in a 100% incidence of diabetes, requiring lifelong insulin therapy.
Early pancreatic cancer may consider neoadjuvant therapy to shrink tumors before surgery. Pancreatic cysts can be initially managed with endoscopic retrograde cholangiopancreatography (ERCP) drainage and observation.
Patients with chronic pancreatitis may opt for partial resection or neurolysis to relieve pain rather than complete removal. However, these alternatives may not cure malignant lesions.
Most patients require long-term insulin dependence after pancreatic resection because the surgery may affect the β-cells in the pancreas that produce insulin. Doctors will adjust the dosage based on residual pancreatic function and blood sugar control. Some patients may gradually regain some insulin secretion capacity, but most need long-term subcutaneous injections or insulin pump therapy. Regular blood sugar monitoring and communication with healthcare providers are essential.
What foods should be avoided after surgery?Initially after surgery, avoid high-fat, high-fiber, and irritating foods such as fried foods, whole grains, and spicy foods to reduce the risk of indigestion or diarrhea. A low-fat, high-protein diet with 5-6 small meals per day is recommended. Consult a nutritionist to develop a personalized diet plan to prevent blood sugar fluctuations or digestive issues caused by enzyme deficiency.
When can I resume normal activities after surgery? What should I pay attention to during rehabilitation?Light activities can typically begin 2-4 weeks post-surgery, following medical advice. Early rehabilitation includes walking and deep breathing exercises, gradually increasing upper limb movements to restore abdominal muscle strength. Avoid strenuous bending, lifting heavy objects, and similar activities for at least 6 weeks, and regularly evaluate the healing of abdominal sutures.
How to manage pancreatic insufficiency after surgery?If residual pancreatic tissue cannot produce enough digestive enzymes, doctors may prescribe pancreatic enzyme supplements (such as pancreatic enzyme replacements), taken with meals to improve fat absorption. Monitoring fat-soluble vitamin absorption is also necessary, with vitamin supplementation if needed. Regular ultrasound or blood glucose tests are recommended to assess functional compensation.
What is the frequency and scope of follow-up examinations after surgery?In the first year post-surgery, imaging tests (such as CT or MRI) and tumor marker assessments are recommended every 3-6 months, then adjusted to annually based on the condition. Blood tests including blood glucose, liver function, and pancreatic enzymes should be monitored every 3-6 months. Immediate medical attention is necessary if abdominal pain or digestive abnormalities occur. Long-term follow-up helps detect complications or recurrence early.
