Objective To analyze characteristics of solid pseudopapillary neoplasm (SPN) of pancreas and to discuss it’s diagnosis and treatment. Methods The clinicopathologic data of 39 patients with pathologically diagnosed as SPN from January 2012 to July 2017 in the First Affiliated Hospital to Xinjiang Medical University were collected, the clinical characteristics, imaging features, diagnosis and treatment methods, and prognosis were analyzed. Results Among the 39 patients, there were 27 benign SPNs and 12 malignant SPNs. There were no significant differences in the gender, age, blood type, clinical manifestations, distribution of tumor sites, morphological features, and proportions of combined calcification, intracapsular hemorrhage, and pancreatic ductal dilatation between the benign and malignant SPN patients (P>0.050). The maximum diameter of the tumor, the integrity of the capsule, and the ratio of the tumor cystic solidity had significant differences (P<0.050) between the benign and malignant SPN patients. That was, in patients with benign SPN, the largest tumor diameter was less than or equal to 5 cm, and the capsule was complete, and the tumor was mainly cystic and solid. Of the 27 patients with benign SPN, 6 underwent the tumor enucleation, 7 underwent the standard pancreatoduodenectomy, 2 underwent the middle pancreas resection, 5 underwent the standard caudal pancreatectomy, and 7 underwent the spleen-preserving caudal pancreatectomy. Of the 12 patients with malignant SPN, 8 underwent the standard pancreatoduodenectomy and 4 underwent the standard caudal pancreatectomy. All the patients were discharged after surgery and no intra-abdominal infection occurred. The pancreatic leakage occurred in 4 patients and recoved after the full drainage. The average follow-up was 24.5 months, no patient had the tumor metastasis or recurrence, and no patient died. Conclusions Incomplete capsule and the largest diameter >5 cm may suggest malignancy of SPN, and near-solid tumors may be indicative of benignancy. Surgery is a crucial and most effective treatment for SPN, and it is suggested that routine radical operation is performed for malignant SPN.
ObjectiveTo summarize experience of multidisciplinary team (MDT) in diagnosis and treatment of rare patient with circumscriptus intrahepatic pneumatosis and explore its clinical differentiation with other common types of intrahepatic pneumatosis.MethodThe clinicopathologic data of rare patient with circumscriptus intrahepatic pneumatosis admitted to the Occupational Disease Hospital of Xinjiang Uygur Autonomous Region were retrospectively analyzed.ResultsA 60-year old female patient was admitted to this hospital with " abdominal pain and septic shock”. After the MDT discussion and analysis, the treatment regimens were decided as follows: the early anti-shock treatment, corrections of electrolyte disorder and hypoalbuminemia, platelet transfusion, ultrasound guided percutaneous catheter drainage (200 mL gas and 10 mL pus, the pneumonic Klebsiella which proved by the bacterial culture). The drainage tube was removed on postoperative day 6. After 5 d of the anti-inflammatory treatment with imipenem and statin sodium injection, it was downgraded to the cefazoxime (the third-generation cephalosporin) injection, and the anti-inflammatory treatment was continued for 6 d as well as the blood glucose was controlled. On the 7th day after the treatment, the right upper abdomen pain was relieved and without positive sign. The abdominal CT showed the localized pneumoconiosis in the right lobe of the liver was completely absorbed. The result of laboratory examination was basically normal. The patient was discharged on the 12th day after the operation and had no discomfort symptoms on month 1 after the operation. The abdominal CT showed the liver was not abnormal.ConclusionSurgeons should be fully aware of various types of intrahepatic pneumatosis so as to sufficiently investigate pathophysiological clue of disease to improve cure rate and reduce complications.
