OBJECTIVES: We sought to clarify the clinical utility of diffusion-weighted magnetic resonance imaging (DWI) for differentiating autoimmune pancreatitis (AIP) from pancreatic cancer. METHODS: Thirteen AIP patients underwent DWI before therapy, and six them after steroid therapy. The extent shape high-intensity areas were compared with those 40 cancer patients. Apparent diffusion coefficient (ADC) values calculated in area therapy a normal body. RESULTS: On DWI, detected as high-signal...
Autoimmune pancreatitis (AIP) and Mikulicz's disease have recently been recognized as pancreatic or salivary gland lesions of IgG4-related systemic disease. These are frequently associated with elevated serum IgG4 levels. This study aimed to clarify clinical implications serial changes levels in diseases.Serial were examined patients diseases. Patients Serial 44 patients: AIP (n=24), (n=8), cancer (n=5), bile duct (n=1), sclerosing cholangitis hypereosinophilic syndrome chronic thyroiditis...
To examine the short-term and long-term clinical courses of patients with autoimmune pancreatitis (AIP) who underwent different treatments identify predictive factors for relapse AIP after steroid therapy.Clinical 50 followed up more than 1 year (median 40 months, range: 12-173 months) were examined. Patients subdivided according to initial as follows: surgical procedures in 10 patients, supportive therapy 11 29 patients.Of surgically treated two later because progressive extensive...
Autoimmune pancreatitis (AIP) is frequently associated with various extrapancreatic lesions. The distribution and frequency of lesions preceding or subsequent to AIP are unknown. aim this study was investigate metachronous AIP.Extrapancreatic were examined clinically, radiologically, histologically in 56 patients.Extrapancreatic 25 (45%) patients. Twenty-nine detected synchronously 18 patients, metachronously 11 Fourteen patients had more than 2 There no significant difference serum IgG4...
Abstract Background Although cardiac fibroma has been regarded as benign tumor, it presents various symptoms and may lead to death. Unfortunately, only a few studies have reported the epidemiology, embryology, histopathology of factors predicting poorer outcome are still obscured. Methods In July 2011 we searched for English Japanese cases using PubMed IgakuChuoZasshi databases. We then extracted sampled raw data from selected publications in accordance with Preferred Reporting Items...
Because the prevalence of carcinoma is high in main-duct intraductal papillary mucinous neoplasms (IPMNs) pancreas, surgical resection recommended for all type IPMNs. This study aimed to investigate clinical predictors malignancy and natural history IPMNs.Preoperative characteristics reliably correlated with 26 surgically resected patients IPMN, long-term outcome 20 conservatively followed IPMN was examined.Age at diagnosis significantly older than patients. Main pancreatic duct (MPD)...
AIM:To clarify the strategy for early diagnosis of pancreaticobiliary maljunction (PBM) without biliary dilatation and to pathologically examine gallbladder before cancer develops. METHODS:The anatomy union pancreatic bile ducts was assessed by using endoscopic retrograde cholangiopancreatography (ERCP).Patients with a long common channel in which communication between maintained even during sphincter contraction were diagnosed as having PBM.Of these, patients maximal diameter duct less than...
The aim of this study was to assess prevailing treatment pancreatolithiasis in Japan.We surveyed clinical data from 1834 patients (1479 men and 355 women) at 125 hospitals.Extracorporeal shock-wave lithotripsy (ESWL) performed alone 103 (5.6%), ESWL plus an endoscopic procedure 446 (24.3%), 261 (14.2%), surgery 167 (9.1%). Other treatments were given 358 (19.5%), whereas 499 (27.2%) received no treatment. Symptoms relieved 85.7% after ESWL, 80.8% alone, 92.8% surgery. Early complication...
Stent-induced ductal change is a complication of endoscopic treatment the main pancreatic duct in chronic pancreatitis. Most previous reports have been based on morphological changes observed via pancreatography. Here, we describe case stent-induced which course mucosal was through peroral pancreatoscopy with videoscopy. The patient presented alcoholic Main stenosis head identified and 10-Fr plastic stent inserted. Follow-up pancreatography revealed focally elevated approximately 4.5 mm at...
The purpose of this study is to clarify the amount and distribution scattered radiation in portable dynamic chest radiography (DCR) compared conventional (CCR), consider appropriate operation methods. Using a X-ray unit, we evaluated imaging time characteristics DCR obtained dose distributions CCR. was measured 200 cm from irradiation field center, varying (5, 10, 15 s). Scattered at 48 points between 100-300 center for CCR (10 (15 s) values were calculated measurements. s each value 10 s....
To evaluate the efficacy of combined endoscopic lithotomy and extracorporeal shock wave lithotripsy (ESWL), additional electrohydraulic (EHL) as needed, for treatment pancreatic duct stones, we retrospectively evaluated 98 patients with chronic pancreatitis lithiasis.For management main (MPD) stones in patients, performed (ET)/ESWL therapy first option. When ET/ESWL was unsuccessful, EHL SpyGlass Direct Visualization system or X-ray guided performed. Outpatient ESWL reserved one final...
Background/Aims In recent years, endoscopic snare papillectomy has been performed to treat tumors of the ampulla Vater. This procedure requires accurate preoperative evaluation. this study, we diagnosed focal extension such by using ultrasonography (EUS) and intraductal (IDUS), examined indications for papillectomy. Methods The subjects were 48 patients with a papillary tumor (13 patients, surgical resection; 35 papillectomy) who evaluated preoperatively EUS IDUS. tumor-node-metastasis...
To clarify the features of acute or chronic pancreatitis and pancreatic tumors associated with complete incomplete pancreas divisum.Clinical diseases (n = 54) 50) divisum were examined.Acute occurred more frequently in patients (22.2%: 12/54, 18.5%: 10/54, respectively) than controls (5.6%: 183/3,246, 4.9%: 159/3,246, respectively; p < 0.01). In 8 pancreatitis, dorsal duct was irregularly dilated from orifice to tail, whereas ventral not (isolated pancreatitis). None 12 consumed heavy...
AIM:To clarify the characteristic features of biliary lesions in patients with autoimmune pancreatitis (AIP) and compare them those primary sclerosing cholangitis (PSC). METHODS:The clinicopathological characteristics 34 (SC) associated AIP were compared 4 PSC.RESULTS: SC occurred predominantly elderly men.Obstructive jaundice was most frequent initial symptom AIP.Only had elevated serum IgG4 levels, diseases more these patients.SC responded well to steroid therapy.Segmental stenosis lower...
AIM:To identify pancreatographic findings that facilitate differentiating between autoimmune pancreatitis (AIP) and pancreatic cancer (PC) on endoscopic retrograde cholangiopancreatography (ERCP) magnetic resonance (MRCP). METHODS:ERCP of 48 AIP 143 PC patients were compared.Diagnostic accuracies for by ERCP MRCP compared in 30 patients. RESULTS:The following suggested a diagnosis rather than PC.Obstruction the main duct (MPD) was more frequently detected (P < 0.001).Skipped MPD lesions only...
Abstract Background and Aim Stent‐induced ductal change is a complication of endoscopic pancreatic stent placement for chronic pancreatitis, potentially leading to irreversible changes that may contribute dysfunction. This study aimed examine the long‐term outcomes stent‐induced evaluate factors correlate with development changes. Methods Between January 2008 December 2022, 52/223 patients pancreatitis in whom an S‐type plastic was successfully placed from main papilla duct stricture were...
