Pancreatic resection surgery is a surgical procedure used to remove part or all of the pancreatic tissue 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 approach varies depending on the extent of resection, including total pancreatectomy, pancreaticoduodenectomy, and others, selected based on the lesion location and the patient's overall health. Modern techniques often incorporate laparoscopic or robotic-assisted methods to reduce trauma and accelerate recovery.
Pancreatic resection can be classified into "Head Resection" and "Body and Tail Resection." The former targets lesions in the pancreatic head, often involving removal of part of the duodenum and bile duct; the latter addresses mid- and posterior segment lesions, potentially preserving some pancreatic function. The mechanism involves thorough removal of diseased tissue to prevent cancer cell spread or organ failure due to chronic inflammation.
In robotic-assisted surgeries, surgeons operate through minimally invasive incisions with precise instruments, reducing tissue damage and enhancing 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 (IPMN), and malignant transformation of pancreatic cysts. Surgery is also necessary for recurrent acute pancreatitis or severe trauma leading to pancreatic rupture.
Additionally, certain hereditary pancreatic diseases such as hereditary pancreatitis, or when lesions invade surrounding 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 conducted to evaluate lesion location and patient metabolic status. Total pancreatectomy necessitates postoperative nutritional support plans.
Pancreaticoduodenectomy involves reconstructing the digestive tract, including suturing the pancreas, bile duct, and intestine, requiring high precision to prevent anastomotic leaks. Postoperative hospital stay typically lasts 7-14 days, adjusted according to recovery progress.
Main benefits include:
Compared to conservative treatments, surgery directly removes diseased tissue, preventing malignant metastasis. 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. Surgery is contraindicated in patients with severe coagulopathy or systemic failure. 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 residual disease. Postoperative oral medications are temporarily halted, with parenteral nutrition provided instead.
Patients who have undergone radiotherapy 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, survival is approximately 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.
Chronic pancreatitis patients may opt for partial resection or neurolysis to relieve pain rather than complete removal. However, these alternatives may not cure malignant conditions.
Most patients require long-term dependence on insulin after pancreatic resection because the surgery may affect the insulin-secreting beta cells of the pancreas. Doctors will adjust the dosage based on residual pancreatic function and blood glucose control. Some patients may gradually regain some insulin secretion, but most need long-term subcutaneous injections or insulin pump therapy. Regular blood glucose monitoring and communication with healthcare providers are essential.
What foods should be avoided after surgery?Initially after surgery, high-fat, high-fiber, and刺激性 foods such as fried foods, whole grains, and spicy foods should be avoided to reduce the risk of indigestion or diarrhea. A low-fat, high-protein diet is recommended, divided into 5-6 small meals daily. Consulting a nutritionist for a personalized diet plan is advised 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 generally 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 heavy bending, lifting, or strenuous activities for at least 6 weeks, and regularly monitor 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 supplementation if needed. Regular ultrasound or blood glucose tests should be performed to assess functional compensation.
What is the frequency and scope of postoperative follow-up examinations?In the first year after surgery, abdominal imaging (such as CT or MRI) and tumor marker tests are recommended every 3-6 months, then adjusted to annually based on condition. Blood tests including blood glucose, liver function, and pancreatic enzymes should be monitored every 3-6 months. Immediate medical attention is required if symptoms such as abdominal pain or digestive abnormalities occur. Long-term follow-up helps detect complications or recurrence early.
