BACKGROUND/AIMS: Quadruple therapy can be considered as a first-line therapy in areas where the resistance rate to clarithromycin is high. Comparison study of triple therapy and quadruple therapy for Helicobacter pylori (H. pylori) eradication is still lacking in Korea despite the increasing prevalence of antibiotic resistance. This study was conducted to compare the efficacy of triple and quadruple therapy as a first-line treatment in H. pylori infected patients with peptic ulcer. METHODS: Consecutive 149 cases of peptic ulcer disease associated with H. pylori infection were randomized either to proton pump inhibitor (PPI, bid), amoxicillin (1,000 mg, bid), and clarithromycin (500 mg, bid) (PAC group) or to PPI (bid), bismuth subcitrate (300 mg, qid), metronidazole (500 mg, tid), and tetracycline (500 mg, qid) (PBMT group) eradication treatments for 7 days. Outcome of eradication therapy was assessed by 13C-urea breath test performed 4-6 weeks after eradication. RESULTS: Eradication rates in PAC and PBMT group were 78.7% (59/75) and 71.6% (53/74) by intention to treat analysis, respectively (p=0.424). By per protocol analysis, eradication rates of PAC and PBMT group were 85.5% (59/69) and 85.5% (53/62), respectively (p=1.012). Adverse reactions occurred in 5 (6.6%) and 7 (9.5%) patients in PAC and PBMT group, respectively (p=0.346). CONCLUSIONS: One week-quadruple therapy as a first-line treatment for H. pylori infection does not offer any advantage over PPI-based triple therapy in Korean patients.

The first family of hereditary pancreatitis was described in 1952. The mode of inheritance is autosomal dominant trait with an 80% of penetrance rate. Although hereditary pancreatitis is rare, this disorder has provided valuable insights in understanding the pathophysiology of pancreatitis and pancreatic cancer. The causative gene of hereditary pancreatitis was identified in 1996 through mutational analysis of genes within chromosome 7q35. Most forms of hereditary pancreatitis are caused by one of two common mutations, R122H in the third exon or N29I in the second exon of the cationic trypsinogen gene (protease serine 1, PRSS1). R122H mutation is the most common PRSS1 mutation. Additional mutations of the cationic trypsinogen gene have been described. In Korea, first family of hereditary pancreatitis with cationic trypsinogen gene mutation revealed an arginine to histidine amino acid substitution at the residue 122. Patients with hereditary pancreatitis present with symptoms at an early age and have significant risk for the development of chronic pancreatitis and pancreatic cancer. The risk of pancreatic cancer is estimated to be 53-fold higher after the age of 50 years than the general population. The risk of pancreatic cancer is not related to the type of mutation. Since hereditary pancreatitis is a strong risk factor for pancreatic cancer, it is important to establish a diagnostic criteria for diagnosis and surveillance. However, there are potential benefits, risks and limitations in genetic testing for hereditary pancreatitis. It is difficult to provide the proper treatment, but recent developments in therapeutic approaches may be helpful in caring hereditary pancreatitis. This article includes the current status, pathogenesis, clinical features, and management of hereditary pancreatitis including the aspects of pancreatic cancer.

The management of pancreatitis remained controversial over the past decades, varying from conservative medical treatment to surgical treatment. However, in recent years, treatment of severe acute pancreatitis is shifting from an early surgical debridement and necrosectomy to an aggressive intensive medical care. While the treatment is conservative in the earlier phase of the disease, surgery might be considered in the later phase. In chronic pancreatitis and in pancreatic pseudocyst, various surgical approaches are available these days. Apart from the conventional open surgery, laparoscopic procedure became popular since it is minimally invasive and effective. In addition, with the great improvements in interventional radiology and endoscopic techniques, multidisciplinary approaches including medical, interventional, and surgical management become much more important in the proper treatment of pancreatitis. In this review, pancreatitis is classified into three categories (acute pancreatitis, chronic pancreatitis, and pancreatic pseudocyst) for convenience, and the surgical treatment is described in each category.

Chronic pancreatitis is a progressive disease without curative treatment. Abdominal pain is the most predominant symptom of chronic pancreatitis that initially brings most of the patients to the physician's attention. Some studies have correlated the course of pain in chronic pancreatitis in comparison with the duration of the disease, progressing exocrine and endocrine pancreatic insufficiency, and morphological changes such as pancreatic calcification and duct abnormalities. Furthermore, the course of pain has been studied after alcohol abstinence or surgery in some groups. However, there are only few well-performed and valid studies, and some of them even have produced diversing results, in part. Further controlled studies harvoring a large number of patients in a multicenter setting should be considered. Therapeutic efforts on chronic pancreatitis have focused on palliative treatment of pain which is present in about 80% of cases. Endoscopic treatment of pain in chronic pancreatitis is useful and feasible in many patients. Selecting candidate for endotherapy is mandatory. Main indication of pancreatic stent insertion in chronic pancreatitis is the presence of an obvious ductal stricture. Complications of chronic pancreatitis are also indications of endoscopic intervention. Exocrine and endocrine insufficiencies should be meticulously managed to prevent complications and to maintain good quality of life.

Medical management of acute pancreatitis relies on supportive care such as fluid resuscitation and pain control. Prophylactic antibiotics can reduce the opportunity of infection in severe pancreatitis. The effect of somatostatin or protease inhibitors still needs to be evaluated through further study. Early endoscopic retrograde cholangiopancreatography (ERCP) can ameliorate the course of severe biliary pancreatitis. Although sterile pancreatic necrosis, acute fluid collection, and pseudocyst usually resolve spontaneously, endoscopic or percutaneous drainages are needed when these complications are infected.

Acute pancreatitis is an inflammatory disease of pancreas which come from various etiologies. The pathologic spectrum of acute pancreatitis varies from mild edematous pancreatitis to severe necrotizing pancreatitis. To diagnose and to predict severity in acute pancreatitis, various biochemical marker, imaging modalities and clinical scoring sytstem are needed. Ideal parameters should be accurate, be performed easily and enable earlier assess. Unfortunately, no ideal parameter is available up to date. Serum amylase and lipase are still useful for the diagnosis but meaningless in predicting severity. C-reactive protein and inflammatory cytokines are promising single parameters to predict the severity. CT finding is also an useful determinant of severity, but is expensive and is delayed in assessment.

Pancreatic inflammatory disease can be classified as acute pancreatitis (AP) and chronic pancreatitis (CP) primarily by clinical criteria, with an obvious difference by restoration of normal function in the former or by permanent residual damage in the latter. Gallstones and alcohol are the most common causes of AP. Recent investigations have established that AP from all cause may disrupt normal stimulus-secretion coupling function within the acinar cell. This disruption within the acinar cell leads to an event termed 'co-localization' in which the digestive and lysosomal enzymes merge resulting in a premature activation of proteases. The mechanisms of inflammatory cells which adhere to endothelial cell are determined by a variety of mediators of cytokines released at the site of tissue damage. Cytokines hold the key for both local and systemic inflammatory response in AP. Besides, CP is a debilitating disease characterized by progressive and irreversible destruction of pancreatic tissue leading to exocrine and endocrine insufficiencies. Alcohol intake is the most common cause of CP. Mutations in the cationic trypsinogen gene were identified as causative gene for hereditary pancreatitis. The recognition of frequent cystic fibrosis transmembrane conductance regulator (CFTR) mutations and serine protease inhibitor, Kazal type 1 (SPINK1) mutations in idiopathic CP has hightened the awareness of importance of genetic mutations in CP. Pancreatic stellate cells represent the main cellular source of extracellular matrix in CP and play a key role in pancreatic fibrosis.

Dieulafoy lesion is an abnormally large calibered submucosal artery associated with a minute mucosal defect in the gastrointestinal mucosa. It is a rare cause of profuse, but intermittent gastrointestinal bleeding. The lesion is usually located in the stomach, although it may occur anywhere in the gastrointestinal tract. Dieulafoy lesion is extremely rare in the neonates. We report two newborn infants with a gastric Dieulafoy lesion which was treated by endoscopic epinephrine injection therapy without complication and recurrence.

Pancreatic metastases are found in up to 40% of patients with small cell lung cancer, but metastasis-induced acute pancreatitis is rare. Treatment of metastasis-induced acute pancreatitis is initially supportive, but failure of conservative management are common. There are few reports on aggressive treatment with chemotherapy which lead to rapid clinical improvement and prolongation of survival in patients with metastasis-induced acute pancreatitis. We experienced a case of metastasis-induced acute pancreatitis in a patient with small cell lung cancer. Despite conservative treatment with dietary restriction and intravenous fluid supply, serum amylase levels increased persistently with severe abdominal pain. After chemotherapy with irinotecan and carboplatin, abdominal pain and serum amylase levels resolved dramatically.

Angiosarcoma is a rare malignant tumor which occurs frequently in the skin and soft subcutis. Moreover, primary gastrointestinal angiosarcomas are very rare. This tumor manifests as non-specific symptoms such as gastrointestinal bleeding, abdominal pain and nausea. The diagnosis is often made at an advanced stage. Surgery, chemotherapy and radiotherapy are the mainstay of treatment. However, the prognosis is very poor. We report a case of primary angiosarcoma of the small intestine presenting as recurrent gastrointestinal bleeding. A 54-year-old man was admitted with recurrent gastrointestinal bleeding. An abdominal CT scan revealed an ileo-ileal intussusception. Segmental resection was performed with ileo-ileal anastomosis. The ileal mass was diagnosed as angiosarcoma on immunohistochemical stain. He received 3 cycles of chemotherapy, but died 5 months after the diagnosis.
