RESUMO
BACKGROUND AND AIM: Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is the most serious adverse event of ERCP. Therefore, it is important to identify high-risk patients who require prophylactic measures. The aim of this study was to develop a practical prediction model for PEP that identifies high-risk patients. METHODS: Patients who underwent ERCP at three tertiary hospitals between April 2010 and September 2012 were enrolled. The dataset was divided into a training set (two centers) and validation set (one center). Using the training set, univariable and multivariable analyses were performed to identify predictive factors for PEP. We constructed a scoring system and evaluated reproducibility using the validation set. RESULTS: A total of 2719 ERCPs were analyzed. PEP developed in 133 cases (4.9%). Risk factors (adjusted odds ratios [OR]) in the training set were a history of PEP (OR: 4.2), intact papilla (OR: 2.4), difficult cannulation (OR: 1.9), pancreatic guidewire-assisted biliary cannulation (OR: 2.2), pancreatic injection (OR: 2.1), pancreatic intraductal ultrasonography (IDUS)/sampling from the pancreatic duct (OR: 2.2), and biliary IDUS/sampling from the biliary tract (OR: 2.8). A scoring system was constructed using these seven clinical variables. The areas under the receiver-operating characteristic curve of this model were 0.799 in the training set and 0.791 in the validation set. In the high-risk group at a score of 3 or higher, the incidence of PEP was 13.4%, and all severe/fatal cases were in the high-risk group. CONCLUSIONS: This scoring system helps to predict each patient's risk and select preventive measures.
RESUMO
A 54-year-old man presented with melena and was conservatively monitored for duodenitis. He developed epigastric pain, and dynamic computed tomography revealed abnormal blood flow in the pancreatic head. The endoscopic retrograde cholangiography revealed that the common bile and pancreatic ducts were simultaneously enhanced, thereby indicating the perforation of an arteriovenous malformation into both ducts. Despite medical treatment, the epigastric pain rapidly worsened and therefore, pancreatoduodenectomy was performed. The present report suggests that if the patient's general condition permits, surgical resection should be actively considered for the treatment of symptomatic pancreatic arteriovenous malformation.

OBJECTIVE: This study's objective was to assess outcomes of a totally conservative strategy for acute cholecystitis (AC) followed by delayed elective cholecystectomy. PATIENTS AND METHODS: Consecutive patients who underwent cholecystectomy for AC were divided into the Emergent and Elective cholecystectomy groups. Patients in the elective cholecystectomy group were divided into early, medium, and late groups according to time from symptoms onset. RESULTS: The success rate for conservative management reached 97.2%. Increased blood loss and a higher conversion rate were significantly associated with the emergent group. Patients in the late group had significantly lower operative time and tended to have lower blood loss and less frequent conversion to open surgery than those in the early and medium groups. CONCLUSIONS: Most AC cases could be managed conservatively, and elective cholecystectomy was performed safely regardless of the time. Elective cholecystectomy carried out in late phase was likely to be associated with decreased surgical difficulty.

BACKGROUND: The present study assessed conservative management of acute cholecystitis (AC) with a focus on percutaneous transhepatic gallbladder aspiration (PTGBA). METHODS: Consecutive 275 patients with AC who underwent PTGBA were reviewed. Patients aged ≥80 years and/or with American Society of Anesthesiologists score III to IV and/or performance status 3 to 4 were defined as high risk. Patients were classified according to duration from symptom onset to first PTGBA: within 3 days (early PTGBA) or over 3 days (late PTGBA). They were also classified according to duration from first PTGBA to surgery: within 30 days (early surgery) or over 30 days (late surgery). RESULTS: A total of 263 patients (95.6%) showed recovery after PTGBA. There were no significant differences in operating time, blood loss, operating procedure, conversion rate to open surgery, postoperative complications, or postoperative hospital stay between the early and late PTGBA groups or between the early and late surgery groups. No significant complications associated with PTGBA or surgery were observed, including in those at high risk. CONCLUSIONS: Percutaneous transhepatic gallbladder aspiration can be a useful alternative for most patients with AC, including those at high risk. Elective cholecystectomy can be performed safely regardless of the timing of PTGBA or surgery.

A 54-year-old woman exhibited pancreatic calcification on abdominal ultrasonography. Diagnostic imaging revealed a 20-mm mass with a 12-mm calcification in the tail of the pancreas. The mass was weakly enhanced in the early phase of contrast-enhanced CT. We performed pancreatectomy and splenectomy. Histopathological diagnosis was a nonfunctioning pancreatic neuroendocrine tumor (PNET), grade 2. This is a rare case of PNET with extensive calcification.

OBJECTIVE: Early cholecystectomy is currently the gold standard treatment for acute cholecystitis (AC). However, the acceptability and safety of this strategy remain in dispute. The aim of this study was to clarify the role of percutaneous transhepatic gallbladder aspiration (PTGBA) in the early management of AC in a single center. METHODS: A total of 147 consecutive patients who were treated with PTGBA for AC from 2008 to 2012 were included in the study. The therapeutic outcomes and adverse events were evaluated. RESULTS: A single PTGBA was adequate for 96 (65.3%) patients with AC. Of the remaining 51 patients, 43 (29.3%) showed an improvement after repeated PTGBA and/or percutaneous transhepatic gallbladder drainage (PTGBD), while semi-emergency cholecystectomy was needed in eight patients. Although five patients experienced adverse events (intra-abdominal hemorrhage in two, bile leakage in two and gallbladder hemorrhage in one), no patient died of treatment-related complications. Subsequently, 87 (59.2%) patients underwent cholecystectomy after PTGBA (a single PTGBA in 48 and repeated PTGBA and/or PTGBD in 39 patients). No significant differences were observed in the conversion rate from laparoscopic surgery to open cholecystectomy, operative time or intraoperative hemorrhage volume between the two groups. CONCLUSIONS: The present study demonstrated the safety and acceptability of treatment with PTGBA for AC at our center. This elective treatment strategy may be a useful alternative option in the treatment of AC.

A 54-year-old man exhibited a pancreatic mass on abdominal ultrasonography. Diagnostic imaging with endoscopic ultrasonography, computed tomography, and magnetic resonance imaging revealed that the mass comprised various internal structures and was not connected to the pancreatic duct. Over a period of 4 years and 2 months, the mass increased from 22mm to 32mm in diameter. Laparoscopic enucleation was performed, and a histopathological diagnosis of a lymphoepithelial cyst (LEC) of the pancreas was obtained. LEC is rare and seldom reported in the literature. Although it is considered to be benign, most case reports indicate that they tend to increase in size. This indicates that LEC should be carefully monitored if surgery is not performed after diagnosis.

OBJECTIVES: The requirements of biliary stents used in the palliation of malignant biliary obstruction are a long duration of patency and minimal adverse effects. Covered self-expandable metal stents (SEMSs) have been shown to prevent tumor ingrowth, which is the most frequent complication of uncovered SEMSs. However, because they are prone to migration, the superiority of covered SEMS has yet to be convincingly demonstrated. The aim of this study was to evaluate the superiority of covered over uncovered SEMSs in the palliation of distal biliary obstruction due to unresectable pancreatic carcinoma, using both stent types with relatively low axial force and uncovered flared ends to prevent their migration. METHODS: From April 2009 to December 2010, 120 patients who were admitted to 22 tertiary-care centers because of distal biliary obstruction from unresectable pancreatic carcinomas were enrolled in this prospective randomized multicenter study. Patients were randomly assigned to receive a covered or uncovered SEMS deployed at the site of the biliary stricture during endoscopic retrograde cholangiopancreatography. Stent patency time, patient survival time, patient survival time without stent dysfunction (time to stent dysfunction or patient death), cause of stent dysfunction (ingrowth, overgrowth, migration, or sludge formation), and serious adverse events were compared between covered and uncovered SEMS groups. RESULTS: Patient survival time in the two groups did not significantly differ (median: 285 and 223 days, respectively; P=0.68). Patient survival time without stent dysfunction was significantly longer in the covered than in the uncovered SEMS group (median: 187 vs. 132 days; P=0.043). Stent patency was also significantly longer in the covered than in the uncovered SEMS group (mean±s.d.: 219.3±159.1 vs. 166.9±124.9 days; P=0.047). Reintervention for stent dysfunction was performed in 14 of 60 patients with covered SEMSs (23%) and in 22 of 60 patients with uncovered SEMSs (37%; P=0.08). Stent dysfunction was caused by tumor ingrowth, tumor overgrowth, and sludge formation in 0 (0%), 3 (5%), and 11 (18%) patients in the covered SEMSs group, and in 15 (25%), 2 (3%), and 6 (10%) patients in the uncovered SEMSs group, respectively. Stent migration was not observed in either group. Rates of tumor overgrowth and sludge formation did not significantly differ between the two groups, whereas the rate of tumor ingrowth was significantly lower in the covered than in the uncovered SEMS group (P<0.01). Acute pancreatitis occurred in only one patient in the covered SEMS group. Acute cholecystitis occurred in one patient in the covered SEMS group and in two patients in the uncovered SEMS group. There was no significant difference between the two groups in the incidence of serious adverse events. CONCLUSIONS: By preventing tumor ingrowth and migration, covered SEMSs with an anti-migration system had a longer duration of patency than uncovered SEMSs, which recommends their use in the palliative treatment of patients with biliary obstruction due to pancreatic carcinomas.

BACKGROUND: We aimed to clarify the lifestyle factors associated with erosive esophagitis and non-erosive reflux disease (NERD) in a Japanese population. METHODS: Among 886 subjects who underwent health screening, we selected, according to their scores on the FSSG (frequency scale for symptoms of gastroesophageal reflux disease; GERD) questionnaire and the findings of upper gastrointestinal endoscopy, 138 subjects with erosive esophagitis (EE), 148 subjects with NERD (absence of esophagitis, FSSG score ≥8, and acid reflux-related symptoms score ≥4), and 565 control subjects (absence of esophagitis and FSSG score ≤7). We compared clinical characteristics and various lifestyle factors in these three groups. RESULTS: The lifestyle factors significantly associated with NERD compared with findings in the control group were intake of egg (odds ratio [OR] 1.89, 95% confidence interval [CI] 1.01-3.50), sleep shortage (OR 2.44, 95% CI 1.54-3.88), and strong psychological stress (OR 1.77, 95% CI 1.18-2.62). In male subjects, current smoking (OR 2.06, 95% CI 1.13-3.74; OR 1.87, 95% CI 1.09-3.20) was a significant risk factor for both NERD and EE. Moreover, alcohol >200 kcal/day (OR 3.99, 95% CI 1.03-15.55) and intake of a large quantity of food at supper (OR 7.85, 95% CI 1.66-37.05) were significant risk factors for EE in subjects with hiatal hernia. Intake of a large quantity of food at supper (OR 2.09, 95% CI 1.06-4.13) was more common in the NERD group than in the EE group. CONCLUSIONS: There were differences in the associated lifestyle factors between patients with NERD and those with EE, and there was also a gender-related difference between these groups.

A 50-year-old man was admitted to our hospital with a chief complaint of melena. An emergency upper gastrointestinal endoscopic study revealed arterial bleeding from a duodenal submucosal tumor, 1.5cm in diameter and about 2cm in an oral direction from the papilla of Vater. Because it was not possible to stop the bleeding, an emergency resection of the tumor was performed. Macroscopically, the ulcerated tumor was approximately 1.5cm in diameter. Histopathologically, the tumor was determined to be located in the accessory papilla of the duodenum. We report here a rare case of bleeding from the accessory duodenal papilla and discuss the literature.

BACKGROUND: No study has compared covered metallic stents with Tannenbaum stents. We evaluated the efficacy of the DoubleLayer stent (DLS) and Covered Wallstent (CWS) in patients with pancreatic head cancer (PHC). PATIENTS & METHODS: This was a multicenter, prospective randomized study. Between October 2005 and December 2007, we enrolled 113 patients (58 DLS, 55 CWS) with unresectable PHC with distal biliary obstructions and observed them for at least 6 months. RESULTS: No significant difference in patient survival was found between groups, with a median survival of 231 and 248 days in the DLS and CWS groups, respectively. The cumulative stent patency was significantly higher (P = 0.0072) in the CWS group. The respective mean and median stent patency was 202 and 133 days in the DLS group and 285 and 419 days in the CWS group. The incidence of DLS occlusion (53.5%) was significantly higher than that of CWS (23.6%; P = 0.0019). The respective causes of occlusion were tumor overgrowth (0, 1), ingrowth (0, 2), sludge (24, 2), food impaction (3, 5), kinking bile duct (2, 0), and other (2, 3). Other complications were cholecystitis (0, 4), pancreatitis (0, 1), migration (1, 5), liver abscess (2, 0), and other (1, 2). No significant difference in the incidence of complications between groups was observed. CONCLUSION: CWS had significantly longer patency than DLS for the management of PHC with obstructive jaundice. The incidence of complications other than stent occlusion was higher in CWS, but this difference did not reach significance.

A 60-year-old man presented with diarrhea and weight loss. Colonoscopy revealed multiple reddish polypoid lesions throughout the gastrointestinal tract and was diagnosed as Cronkhite-Canada syndrome (CCS). Prednisolone therapy caused regression of polyps. Some of them were suspected to be early colon cancers and adenomas. We endoscopically performed mucosal resection for 15 polyps after prednisolone therapy. Histological examination of one of polyps showed invasion of the submucosal layer and colon resection was performed. This case suggests that diagnosis and treatment are important in polyps of CCS.

OBJECTIVE: Endoscopic sphincterotomy (ES) is a well-established standard method for treating common bile duct stones. However, biliary sphincter function is impaired after the treatment, and this may influence the long-term outcomes. In this study, we aimed to compare the long-term outcomes after ES with those after endoscopic papillary balloon dilation (EPBD) because the latter procedure is expected to preserve biliary sphincter function better than ES. DESIGN: A prospective follow-up of the original cohort in a previously randomized, controlled trial to compare the early outcomes after ES and EPBD. SETTING: Eleven centers, including 6 clinical practices and 5 academic institutions. PATIENTS: A total of 282 patients with common bile duct stones were randomly selected to undergo ES (n = 144) or EPBD (n = 138) in the previous study. INTERVENTIONS: ES or EPBD. MAIN OUTCOME MEASUREMENTS: Complications after ES or EPBD occurring during long-term follow-up. RESULTS: The patients were followed up annually after the treatment. The median duration of the follow-up was 6.7 years. Morbidity was observed in 36 (25.0%) and 14 (10.1%) of the patients who underwent ES and EPBD, respectively (P = .0016). Kaplan-Meier analysis revealed a significantly higher incidence of biliary complications in the ES group than in the EPBD group (P = .0011). Multivariate analysis showed that ES, periampullary diverticulum, and in situ gallbladder stones were independent risk factors for stone recurrence. CONCLUSIONS: During long-term follow-up, patients who underwent ES had significantly more biliary complications than those who underwent EPBD. The biliary sphincter dysfunction after ES results in additional late complications.

A 60-year-old man was admitted to our department for further evaluation of main pancreatic duct dilatation detected on ultrasonography. Endoscopic retrograde cholangiopancreatography showed stenosis of the main pancreatic duct at the junction of the pancreatic head and body. Brush cytology revealed pancreatic ductal carcinoma. Histological examination of the resected pancreas showed a 15-mm in length intraductal growth of carcinoma in situ in the main pancreatic duct, 10mm of which showed microinvasion. There was also atypical hyperplasia at a branch pancreatic duct near the lesion. It was suspected to be an initial stage of pancreatic ductal carcinoma. Intraductal progression type and non-progression type are often suspected in a case showing progression of carcinoma in situ to pancreatic ductal carcinoma, and this case was thought to be intraductal progression.

OBJECTIVE: Recently, guidelines for the treatment and prevention of ulcers induced by non-steroidal anti-inflammatory drugs (NSAIDs) were established. This study investigated the association between the current adherence to the guidelines and the incidence of gastric mucosal lesions caused by NSAIDs. METHODS: This study included 254 NSAIDs users (128 regular and 126 on-demand users) who had undergone upper gastrointestinal endoscopy. The patients were characterized as high risk based on the following: age 65 years or older, history of peptic ulcers, concurrent use of corticosteroids or anticoagulants, and high-dose NSAIDs use. Adherence was defined as the prescription of NSAIDs with proton pump inhibitors, prostaglandin analogues, or high-dose histamine 2 receptor antagonists in high-risk NSAIDs user. The severity of gastric mucosal lesions was evaluated using the modified LANZA score (MLS). RESULTS: Seventy-nine (61.7%) of the regular NSAIDs users and 65 (51.6%) of the on-demand NSAIDs users met our definition of high-risk patients. Adherence in the regular NSAIDs users and on-demand NSAIDs users was 25 (31.7%) and 16 (24.6%), respectively. The incidence of gastric mucosal lesions (MLS ⧠1) was significantly higher in the nonadherence group than in the adherence group for both regular NSAIDs users (59.3 vs. 28.0%, P = 0.01) and on-demand NSAIDs users (63.3 vs. 25.0%, P = 0.01). Gastric ulcers in the regular NSAIDs users were more frequently observed in the nonadherence group than in the adherence group (29.6 vs. 4.0%, P < 0.01). CONCLUSION: Nonadherence was associated with a high prevalence of NSAIDs-induced gastric mucosal lesions.

A 51-year-old woman with an unresectable pancreatic tumor that was histologically diagnosed as an adenosquamous carcinoma underwent chemoradiotherapy with 5-fluourouracil (FU) and low-dose cisplatin (low-dose FP). Because we recognized a partial response to the chemoradiotherapy, we subsequently administered combined chemotherapy with S-1 and cisplatin. After one course of this combined chemotherapy, the tumor was further reduced in size and became difficult to discern on abdominal computed tomography (CT). We have continued to administer the S-1 and cisplatin combined chemotherapy, and the patient is still alive. After 20 months of treatment, the tumor has not recurred (as assessed by abdominal CT). Additionally, we have not seen elevation of tumor markers. This report presents the successful use of chemoradiotherapy with low-dose FP and additional combined chemotherapy with S-1 and cisplatin for unresectable pancreatic adenosquamous carcinoma.

To evaluate ambulatory patient cancer chemotherapy, the clinical response, toxicities and survival time were analysed among 19 patients with non-curative or recurrent colorectal cancer who were treated by Uracil/Tegafur (UFT) plus oral Leucovorin (UZEL) for the past 2 years. The patients were administered UFT (300 mg/m2/day) and UZEL (75 mg/body/day) for 28 days with a one-week interval every 35 days as one course.A partial response (PR) was observed in 6 patients (31.6%) and stable disease (SD) in 8. The median survival time was 16 months. Although nausea/vomiting, diarrhea and leucopenia were noted, no severe side effects were observed. These results suggested that UFT plus Leucovorin therapy might be a useful cancer chemotherapy for ambulatory patients with advanced colorectal cancer.

A 62-year-old man had been followed because of an elevated serum level of carcinoembryonic antigen without the detection of any cancer lesions. However, there was a sudden increase in the serum level of carcinoembryonic antigen, and abdominal imagings showed a hepatic tumor with peripheral intrahepatic bile duct dilatation, and a submucosal tumor at the sigmoid colon with intact mucosa. Histopathological findings showed that the hepatic tumor had perineural invasion, suggesting an intrahepatic cholangiocarcinoma, and that the colon tumor infiltrated the submucosa, while its mucosa was intact. Both tumors showed similar pathological features and were positive for cytokeratin 20 and 7. These findings suggested intrahepatic cholangiocarcinoma with metastatic sigmoid colon cancer.

BACKGROUND: Endoscopic papillary balloon dilatation may be an alternative to endoscopic sphincterotomy in the treatment of bile duct stones. However, there is a controversy as to the effectiveness and safety of endoscopic papillary balloon dilatation. METHODS: Two hundred eighty-two patients with bile duct stones were enrolled and randomized to an endoscopic sphincterotomy or endoscopic papillary balloon dilatation group. The success rate for duct clearance as well as the frequency and types of complications were evaluated prospectively. Endoscopic sphincterotomy was performed in a standard manner. Endoscopic papillary balloon dilatation was carried out with gradual inflation of a 4-, 6-, or 8-mm diameter balloon. RESULTS: Complete duct clearance was achieved in 100% in the endoscopic sphincterotomy group and 99.3% in the endoscopic papillary balloon dilatation group (not significant). Complications occurred in 11.8% of patients in the endoscopic sphincterotomy group and 14.5% of those in the endoscopic papillary balloon dilatation group (not significant). No complication was severe; there was no mortality. The frequency of acute pancreatitis was higher in the endoscopic papillary balloon dilatation group than the endoscopic sphincterotomy group (respectively, 10.9% vs. 2.8%; p < 0.045). Hemorrhage occurred only in the endoscopic sphincterotomy group. CONCLUSIONS: Endoscopic sphincterotomy and endoscopic papillary balloon dilatation were approximately equal in terms of successful clearance of bile duct stones. They were also similar with respect to overall complications. Endoscopic papillary balloon dilatation is an alternative to endoscopic sphincterotomy as a treatment of bile duct stones.
