Pancreatitis causing abdominal distension and back pain should be treated in regular hospitals, and standardized treatments such as acid suppression, enzyme suppression, pain relief and anti-inflammation should be carried out. Acute pancreatitis is an inflammation caused by the abnormal activation of pancreatic digestive enzymes on the pancreas itself and the surrounding organs, radiating pain in the lower back and abdominal distension are the main clinical symptoms of acute pancreatitis. Clinical principles of early acute pancreatitis treatment are early fluid resuscitation, nutritional support, dynamic assessment of disease development, maintenance of water-electrolyte balance, organ function support, prevention and treatment of local and systemic complications. Fasting, gastrointestinal decompression, use of proton pump inhibitors (omeprazole, pantoprazole, etc.), pancreatic enzyme inhibitors (growth inhibitor, octreotide, etc.) to inhibit pancreatic enzyme secretion and activation should be carried out. At the same time, pethidine may be used for analgesia. When infection occurs, antibiotics (cefoperazone, moxifloxacin, etc.) should be used for treatment based on drug sensitivity test, etc. Some cases of severe pancreatitis also require surgical treatment to clean up the necrotic tissue and drain the fluid locally. When acute pancreatitis occurs and there is radiating pain in the lower back, it means that the inflammation is more serious at this time, and it is recommended to go to the hospital for treatment in time to avoid delaying the condition.
