ABSTRACT

Cholangiocarcinoma (bile duct cancer) is classified into intrahepatic and extrahepatic cholangiocarcinoma (perihilar and distal cholangiocarcinoma) according to the anatomical location of the lesion. The incidence of extrahepatic cholangiocarcinoma has been relatively stagnant in recent decades, but intrahepatic cholangiocarcinoma is steadily increasing worldwide, requiring attention. Various classification systems based on gross growth patterns, histological findings, and tumor-derived cells, as well as classification based on existing anatomical location, have been proposed, however, the consensus has not been established yet. Intrahepatic cholangiocarcinoma is a carcinoma with an extremely poor prognosis. Complete tumor resection is the only curative treatment. The overall survival rate for 5 years after surgery is 15% to 40%, but recurrence after surgery is observed in 2/3 patients. Therefore, determining the right stage before surgery and selecting an appropriate treatment method through a multidisciplinary approach is a very important process in determining proper treatment. Systemic therapy may be used for locally advanced biliary tract cancer or metastatic biliary tract cancer where surgery is not possible. However, the effectiveness of traditional anticancer chemotherapeutic agents is rather pessimistic, therefore treatments using molecular biological properties have recently been attempted. Finding a way to increase the number of resectable cases through early diagnosis is one of the main challenges. In addition, it is also hoped that the selection of new therapeutic targets and therapeutics will be possible as a result of advanced research on gene expression profiles and mutations in cholangiocarcinoma.

ABSTRACT

A 51-year-old woman visited the emergency room with severe abdominal pain of acute onset. She had undergone a breast cancer operation one year previously and had been taking a half-dose (10 mg per day) of tamoxifen for 6 months. She was diagnosed with severe acute necrotizing pancreatitis. She had no other specific underlying disease or medical history. She did not drink alcohol and showed no gallstones on endoscopic ultrasound examination. Her blood triglyceride level had been normal before tamoxifen but had gradually increased to 2,534 mg/dL 6 months after beginning tamoxifen. Tamoxifen was regarded as a very likely causative factor for her necrotizing pancreatitis. After discontinuing the drug and receiving supportive care, she eventually recovered, and her blood triglyceride levels dropped to a normal range. Tamoxifen may be a useful drug for treating breast cancer, but doctors should pay attention to the patient's blood triglyceride level during the medication regimen.

ABSTRACT

BACKGROUND/AIMS: The aim of this study is to describe the outcome of the national survey and to determine the endoscopic retrograde cholangiopancreatography (ERCP) quality in Korea by comparing with the quality indicators. METHODS: We used the database of Health Insurance Review & Assessment Service and then performed anonymous national survey. RESULTS: Completed questionnaires were returned by 129 of 157 ERCP endoscopists. In Korea, annual ERCP rates have been consistently increased over years. Individual ERCP volume was high (>200 per year) in about half of ERCP endoscopists. Most ERCP endoscopists performed all of level I procedures. However, manometry, cholangiopancreatoscopy, and pancreatic procedures were performed mostly in institutions with high hospital volume. The rate of overall success was more than 90% in most ERCP endoscopists. However, the rate of precut sphincterotomy was high in more than a fourth of ERCP endoscopists. Twelve ERCP endoscopists experienced post-ERCP mortality within recent 1 year. ERCP training and radiation protection during ERCP did not meet the standard of quality indicators especially in institutions with low or moderate hospital volume. CONCLUSIONS: Technical issues during ERCP procedures in Korea fulfill the standard of quality indicators. However, a great effort is needed to improve issues about ERCP training and radiation protection.

ABSTRACT

Hypertriglyceridemia a major cause of acute pancreatitis, accounting for up to 10% of all cases. The pathophysiological mechanism of hypertriglyceridemia-induced acute pancreatitis (HTGP) is presumed to involve the hydrolysis of triglycerides by pancreatic lipase resulting in an excess of free fatty acids and elevated chylomicrons, which are thought to increase plasma viscosity and induce ischemia and inflammation in pancreatic tissue. Although the clinical course of HTGP is similar to other forms of acute pancreatitis, the clinical severity and associated complications are significantly higher in patients with HTGP. Therefore, an accurate diagnosis is essential for treatment and prevention of disease recurrence. At present, there are no approved guidelines for the management of HTGP. Different treatment modalities such as apheresis/plasmapheresis, insulin, heparin, fibric acids, and omega-3 fatty acids have been successfully implemented to reduce serum triglycerides. Following acute phase management, lifestyle modifications including dietary adjustments and drug therapy are important for the long-term management of HTGP and the prevention of relapse. Additional studies are required to produce generalized and efficient treatment guidelines for HTGP.

ABSTRACT

BACKGROUND/AIMS: Presence of enhanced mural nodules, which can be visualized using computed tomography (CT), is one of high-risk stigmata in branch-duct intraductal papillary mucinous neoplasms (BD-IPMNs). Conversely, the absence of enhanced mural nodules on preoperative imaging does not exclude malignant risk. The present study aimed to investigate other morphological features as predictors of malignancy in “pure” BD-IPMNs without enhanced mural nodules on CT. METHODS: This retrospective study included 180 patients with surgically confirmed “pure” BD-IPMNs of the pancreas and no enhanced mural nodules on preoperative CT. The study was conducted at 15 tertiary referral centers throughout South Korea. Univariate and multivariate analyses were used to identify significant predictors of malignancy. RESULTS: BD-IPMNs with low-grade (n=84) or moderate-grade (n=76) dysplasia were classified as benign; those with high-grade dysplasia (n=8) or invasive carcinoma (n=12) were classified as malignant. The multivariate analysis revealed that cyst size ≥30 mm (odds ratio, 8.6; p=0.001) and main pancreatic duct diameter ≥5 mm (odds ratio, 4.1; p=0.01) were independent risk factors for malignancy in “pure” BD-IPMNs without enhanced mural nodules on CT. Endoscopic ultrasound detected enhanced mural nodules (6/82) that had been missed on CT, and two IPMNs with enhanced mural nodules were malignant. CONCLUSIONS: In patients with “pure” BD-IPMNs who have no enhanced mural nodules on CT, cyst size ≥30 mm and main pancreatic duct diameter ≥5 mm may be associated with malignancy.

ABSTRACT

Endoscopic retrograde cholangiopancreatography (ERCP) is an invasive procedure carrying potential complication such as pancreatitis, hemorrhage, perforation and cholangitis. Most of those complications are mild and usually need a short additional hospitalization periods. Perforation, however, often requires surgical intervention and in this case, the rate of mortality is up to 10%. Prompt diagnosis and proper management are key determinants for successful outcome. For this, endoscopist should be aware of possibility of perforation before procedure especially in high risk patients with altered anatomy such as prior Billroth II or Roux-en-Y anastomosis. After diagnosis of perforation, multidisciplinary approach involving medical, surgical and radiologic interventional subspecialties, is essential. Usually, surgical treatment is needed for type I free wall perforation and medical and endoscopic treatments are recommended for type II-IV perforation. Recently, several anecdotal studies reported successful endoscopic treatment using new devices for type I duodenal wall perforation but it is not warranted that endoscopic treatments can substitute the surgical intervention.

ABSTRACT

BACKGROUND/AIMS: Complications by ingested foreign bodies are uncommon, since successful removal by endoscopy occurs in most cases. However, severe complications, such as perforation, can result in death. The aim of this study was to determine the risk factors associated with severe complications in patients with esophageal foreign bodies. METHODS: This study involved 298 patients who underwent successful removal of an esophageal foreign body between January 2001 and December 2014 at Dankook University Hospital. Medical records were reviewed retrospectively. Severe complications were defined as laceration, unstoppable bleeding with simple irrigation, or perforation. Risk factors for severe complications were analyzed using multivariate logistic regression. RESULTS: The most common foreign bodies in adults and pediatrics were fish bones (52.0%) and coins (61.0%). Complications included erosion, ulcer, laceration, bleeding, and perforation. Using multivariate analysis, the type (fish bone, odds ratio [OR] = 2.306, p = 0.004) and size (> 25 mm, OR = 2.614, p = 0.001) of the obstruction and duration of impaction (> 24 hours, OR = 1.887, p = 0.035) were risk factors for severe complications including laceration, bleeding, and perforation. For perforation, duration of impaction (> 24 hours, OR = 41.700, p = 0.005) was a statistically significant risk factor. In two patients, delayed perforation occurred despite successful endoscopic removal of the foreign body. CONCLUSIONS: Patients with esophageal fish bone foreign bodies, foreign bodies larger than 25 mm, and a duration of impaction longer than 24 hours should be treated carefully considering the possibility of severe complications. Specifically, patients with a duration of impaction longer than 24 hours should be closely observed due to increased risk of perforation and potential delayed perforation even after successful endoscopic removal.

ABSTRACT

Until 2012, a total of 48 cases of diphyllobothriasis had been reported in Korea, all of which were morphologically identified as Diphyllobothrium latum. However, some of these specimens were analyzed by nucleotide sequencing of the mitochondrial cox1 gene, which showed that all were D. nihonkaiense, not D. latum. After that, 3 further cases of diphyllobothriasis were confirmed as D. nihonkaiense. In the present study, 3 new cases of D. nihonkaiense were detected from 2011 through 2013. The hosts were infected through consumption of salmonid fishes, such as the trout or salmon, and 2 of them experienced severe diarrhea prior to proglottid passage. All of the tapeworms were confirmed to be D. nihonkaiense by genetic identification. This proved again that most diphyllobothriasis in Korea have been caused by D. nihonkaiense.

ABSTRACT

BACKGROUND/AIMS: Epithelial-mesenchymal transition (EMT)-related proteins may exhibit differential expression in intestinal type or pancreatobiliary type ampulla of Vater carcinomas (AVCs). We evaluated the expression of E-cadherin, beta-catenin, and S100A4 in intestinal and nonintestinal type AVCs and analyzed their relationships with clinicopathological variables and survival. METHODS: A clinicopathological review of 105 patients with AVCs and immunohistochemical staining for E-cadherin, beta-catenin, and S100A4 were performed. The association between clinicopathological parameters, histological type, and expression of EMT proteins and their effects on survival were analyzed. RESULTS: Sixty-five intestinal type, 35 pancreatobiliary type, and five other types of AVCs were identified. The severity of EMT changes differed between the AVC types; membranous loss of E-cadherin and beta-catenin was observed in nonintestinal type tumors, whereas aberrant nonmembranous beta-catenin expression was observed in intestinal type tumors. EMT-related changes were more pronounced in the invasive tumor margin than in the tumor center, and these EMT-related changes were related to tumor aggressiveness. Among the clinicopathological parameters, a desmoplastic reaction was related to overall survival, and the reaction was more severe in nonintestinal type than in intestinal type AVCs. CONCLUSIONS: Dysregulation of E-cadherin, beta-cadherin, and S100A4 expression may play a role in the carcinogenesis and tumor progression of AVCs.

ABSTRACT

A bezoar is a mass formed by the accumulation of digested food. A biliary bezoar, namely a bezoar formed in the bile duct, is rare, which occurs mostly in patients who formerly underwent cholecystectomy. It appears that incompetent sphincter produces occasional reverse flow of foreign bodies including undigested food from the alimentary canal into the bile tract. Surgical treatment is used for huge biliary bezoar which is too huge to be removed by nonsurgical treatment. Extracorporeal shock wave lithotripsy (ESWL) is mostly used to fragment renal or urinary calculi, but may be sparingly used against biliary calculi. This is to report the rare case of a patient with biliary bezoar who formerly underwent open cholecystectomy and choledocoduodenostomy. The patient's huge biliary bezoar was removed by ESWL and the successive execution of endoscopic retrograde cholangio pancreatography (ERCP). ESWL is expected to be a comparatively safe and convenient solution to huge biliary bezoars.

ABSTRACT

BACKGROUND/AIMS: Acute hepatitis A (HAV) is markedly increasing recently on. Some patients with acute hepatitis A show severe clinical course. The seroprevalence rate of IgG anti-HAV has been changing with the regions and the times. Vaccination and seroconversion rate of HAV are not well known. In this study, we aimed to study the difference of seroprevalence rate of IgG anti-HAV according to various clinical factors and to know the vaccination rate and seroconversion rate below 10 years old in the central region of South Korea including Cheonan city. METHODS: Seven hundred seventy two subjects were included in the study from January to September 2009. We analyzed seroprevalence rate of IgG anti-HAV according to sex, age, region, and other viral markers. We interviewed the history of vaccination(1st, 2nd) and analyzed seroconversion rate according to vaccination time below 10 years old. RESULTS: The total seroprevalence rate of IgG anti-HAV was 65.3%. The seroprevalence rate of IgG anti-HAV rate in 2nd, 3rd, and 4th decade was very low (1.9%, 18.8%, 44.8%). The vaccination rate of children was about 50%. The seroconversion rate after 1st, and 2nd vaccination were 85%, 96%. CONCLUSIONS: Catch-up vaccination for teenagers and young adults is needed. Immunizing children with HAV vaccine as a routine schedule should be considered.

ABSTRACT

BACKGROUND/AIMS: An ectopic opening of the common bile duct (CBD) into the duodenal bulb is known to cause biliary tract diseases or peptic ulcer. Yet such a case is extremely rare and the clinical significance of this malformation has not yet been clarified. METHODS: Ten patients with an ectopic opening in the duodenal bulb and who were treated at 4 hospitals in the Chungcheong province area were enrolled. Their clinical and radiographic features and the treatment for their combined biliary diseases were retrospectively analysed. RESULTS: The mean age of the ten patients was 73 years (range: 38~84 years, 8 men, 2 women) Eight of 10 patients had clinical signs and symptoms (RUQ abdominal pain: 5, epigastric pain: 3, fever: 3, Melena: 1). The two patients without symptoms were incidentally found to have an ectopic orifice during the evaluation for bile duct dilatation and a regular health check-up, respectively. Nine had duodenal ulcer scars or bulb deformities. Four had active duodenal ulcers and one of them had bleeding from the active duodenal ulcer, which was treated by endoscopic sclerotheraphy. Six of the 10 patients (60%) had biliary tract diseases (CBD stones: 4, cholangitis without CBD stone: 1, IHD stone: 1). Cholangiography was used for evaluation in 9 patients, and it showed dilatation of the CBD or IHD in 7 (78%), a tapered common bile duct at the distal CBD in 7 (78%) and a hook-shaped distal CBD in 8 (89%). Six patients' biliary tract diseases were treated endoscopically (ERCP: 4, PTCS: 2). Duodenal perforation occurred in 1 (10%), who was successfully managed by medical treatment. CONCLUSIONS: An ectopic opening of the CBD in the duodenal bulb is frequently associated with recurrent duodenal ulcer and biliary tract disease. Combined biliary tract disease can be successfully treated endoscopically.

ABSTRACT

Granular cell tumor is relatively uncommon, it is usually benign and it can be located anywhere throughout the body. It is uncommon in the digestive tract, and especially in the colon and rectum. The endosonographic features of granular cell tumor are usually a relatively hypoechoic, heterogenous lesion in the submucosa, but this tumor has rarely been reported in the colon. We report here on two cases of granular cell tumors of the colon that were observed by using endoscopic ultrasonograpy for making the differential diagnosis of a submucosal tumor and these tumors were confirmed by microscopic examinations after endoscopic mucosal resection.

ABSTRACT

Acalculous hemorrhagic cholecystitis is a rare complication of acute cholecystitis and is associated with a high mortality rate. We present a case of acalculous hemorrhagic cholecystitis with hematoma in the gallbladder lumen, which was diagnosed using magnetic resonance imaging (MRI). The T1- & T2-weighted MRI revealed gallbladder distension with a hypointense intraluminal hematoma. The excellent tissue contrast provided by MRI is useful for detecting hematomas in the cases of hemorrhagic cholecystitis.

ABSTRACT

The jaundice in hepatocellular carcinoma patient can be found when the tumor progresses or hepatic function deteriorates. Rarely, it can be occurred when the bile duct is obstructed. The main reason of obstructive jaundice in hepatocellular carcinoma is bile duct invasion of tumor, tumor thrombus, blood clot of hemobilia and direct bile compression by tumor or metastatic lymph node. Although the tumor thrombi among them is difficult to think, prompt diagnosis and treatment should be done because the symptom and prognosis can be improved by removal of the tumor thrombus. We experienced a case of hepatocellular carcinoma patient associated with obstructive jaundice caused by tumor thrombus after transarterial chemoembolization (TACE). The tumor thrombus was removed by endoscopic retrograde cholangiopancreatography (ERCP) and confirmed as degenerated hepatocellular carcinoma cell.

ABSTRACT

BACKGROUND/AIMS: Cyclooxygenase-2 (COX-2) inhibitors reportedly inhibit the growth of hepatocellular carcinoma (HCC) via caspase-dependent or caspase-independent apoptosis, which is due to COX-2 being associated with hepatocarcinogenesis. Survivin is highly expressed in most human cancers, but the mechanism regulating survivin expression remains unclear. We investigated the regulatory expression of survivin in selective-COX-2-inhibitor-induced growth inhibition of hepatoma cells. METHODS: After treatment with NS-398 (a selective COX-2 inhibitor) at various concentrations (10, 50, 100, 150, and 200 micrometer), the growth inhibition of Hep3B hepatoma cells was assessed by an MTT cell-viability assay, DNA fragmentation gel analysis, and flow cytometry. The expression of survivin transcript was analyzed by reverse-transcription polymerase chain reactions. RESULTS: NS-398 inhibited the growth of hepatoma cells by an amount dependent on the concentration and the time since treatment. Apoptotic DNA ladder and flow-cytometry shifting to the sub-G1 phase were revealed in NS-398-induced growth inhibition of hepatoma cells. NS-398 suppressed the expression of the survivin gene in a concentration- and time-dependent manner. CONCLUSIONS: Survivin was down-regulated in the growth inhibition of hepatoma cells induced by a selective COX-2 inhibitor, NS-398, in a concentration- and time-dependent manner. These results suggest the therapeutic inhibition of COX-2 via suppression of survivin in HCC.

ABSTRACT

BACKGROUND/AIMS: Focal nodular hyperplasia (FNH) is mandatory to be differentiated from other hepatic tumorous conditions such as hepatocellular carcinoma and adenoma. The purpose of this study was to explore the clinical, radiological and pathological features of FNH cases reported in Korea. METHODS: We have searched the journals from the web site "http://koreamed.org" using keywords "focal nodular hyperplasia" and "liver" - total of 38 cases of FNH, 37 cases from 17 published articles and one case from our experience confirmed histologically, were reviewed and analyzed. RESULTS: Thirty eight cases were diagnosed between gestational age of 36 weeks and 67 years. Seventeen female patients (45%) had no history of taking oral contraceptives. Twenty cases (52.6%) experienced clinical symptoms such as abdominal pain and palpable mass. Computed tomography revealed contrast-enhancement in 34 nodules (85%) and typical central stellate scar in 9 (22.5%) of 40 nodules. Magnetic resonance imaging showed T1 weighted low signal in 18 (60%) and T2 weighted high signal in 22 (73.3%) of 30 nodules. Six (60%) of 10 cases showed hypervascular staining on hepatic angiography. Among 38 cases, 32 (84.2%) cases had single nodule and their mean size was 3.9 cm (0.5-16 cm). Pathologically, fibrous septa, proliferation of bile ductules and arterial wall thickening were seen in most cases. CONCLUSIONS: Of all the FNH cases reported in Korea, there were some differences in clinical aspects of sex ratio, accompanying clinical symptoms, and relationship with oral contraceptives, compared with previous reports. Further prospective studies are needed by means of nation-wide clinical survey and analysis.

ABSTRACT

Lamivudine is widely used for the treatment of chronic hepatitis B infection because of it's remarkable antiviral efficacy and safety. We report a case of severe skin eruption caused by lamivudine. A 47-year-old female was admitted because of jaundice and itching sensation. She was diagnosed as chronic hepatitis B infection a few years ago but did not receive any specific treatment. Laboratory data showed acute deterioration of chronic hepatitis B infection. We prescribed lamivudine as a rescue therapy. Her general condition improved and lab data showed improvement in liver function test thereafter. However, she complained of severe skin eruption and itching sensation a few days after the discharge. We stopped lamivudine because the symptoms did not improve despite the use of anti-histamine. Skin biopsy showed interface dermatitis. After stopping lamivudine, her symptoms improved. However, the skin eruption developed again after lamivudine was restarted. Adefovir was used instead, and the patient did not experience any further skin problems since then.
