Objective To evaluate the safety and efficacy of endoscopic retrograde cholangiopancreatography (ERCP) for the diagnosis and treatment of pancreas divisum(PD) associated with recurrent acute pancreatitis(RAP) in children and teenagers. Methods Data of patients with symptomatic PD associated with RAP under 18 years old who were diagnosed and treated with ERCP from January 2011 to January 2015 were retrospectively analyzed. Patients with complete pancreas divisum underwent endoscopic minor sphincterotomy combined with dorsal duct stenting ( ESCS ) , and those with incomplete pancreas divisum underwent bi?papilla endoscopic sphincterotomy combined with dorsal duct stenting ( Bi?ESCS ) . ERCP?related data, complications were recorded. Long?term follow?up was conducted for procedure related complications. Results Nine patients with symptomatic PD associated with RAP were firstly diagnosed. A total of 18 ERCP procedures were performed in these patients, with success rate of 100. 0% ( 18/18) in the minor papilla cannulation, and mild ERCP?related complication rate of 11. 1% ( 2/18) . One was acute mild pancreatitis and the other was hyperamylasemia. During follow?up from 3 to 60 months, all patients had pain relief, among whom 7 were asymptomatic, with no onset of acute pancreatitis. Dorsal ducts of all patients were not obviously dilated in MRCP or CT scan. All patients gained weight and presented normal physical and intelligence development. Conclusion Symptomatic PD associated with RAP can be completely diagnosed with ERCP . ESCS and Bi?ESCS are safe and effective endoscopic treatment techniques for pediatric cases.

BACKGROUND:
The incidence and the mortality of lung cancer rank first among all malignant tumors and it seriously affects human health. The common types of non-small cell lung cancer (NSCLC) are adenocarcinoma and squamous carcinoma with clinical research and more attention, while adenosquamous carcinoma is a rare pathological subtype of lung cancer, which clinical features and prognostic factors are not yet fully understood. The purpose of this study is to analyze the clinical features and prognosis of lung adenosquamous carcinoma, and construct a nomogram to predict the patients' prognosis.
METHODS:
We obtained the data of adenosquamous carcinoma patients diagnosed between 2010 and 2015 in the Surveillance, Epidemiology, and End Results (SEER) database of the United States, and compared their clinical features and prognosis with those of lung adenocarcinoma and lung squamous cell carcinoma patients in the same period. Then we used univariate and multivariate analyses to explore the independent prognostic factors of adenosquamous carcinoma. Finally, we constructed and validated a nomogram to visually predict the outcomes of lung adenosquamous carcinoma.
RESULTS:
1,453 patients with lung adenosquamous carcinoma were finally included. Compared with patients with lung adenocarcinoma and lung squamous cell carcinoma, the distributions of lung adenocarcinoma patients in most of the variables were medium between lung adenocarcinoma and squamous cell carcinoma. The prognosis of adenosquamous carcinoma was better than that of lung squamous cell carcinoma, but worse than that of lung adenocarcinoma. Multivariate analysis showed that age, differentiation, tumor-node-metastasis (TNM), surgery, and chemotherapy were independent prognostic factors (all P were less than 0.001). We constructed a nomogram with a C-index of 0.783 (0.767-0.799). The distinction test and consistency test showed that the nomogram could predict the patient's prognosis effectively.
CONCLUSIONS
Lung adenosquamous carcinoma has unique clinical, pathological, and prognostic characteristics. Age, differentiation, T, N, M, surgery, and chemotherapy status are independent predictors of prognosis in patients with adenosquamous carcinoma. Our nomogram can efficiently predict the prognosis of patients.
