Attenuated familial adenomatous polyposis (AFAP) is a variant of familial adenomatous polyposis with fewer than one hundred colorectal polyps and a later age of onset of the cancer. Here, we report two cases of AFAP within family members. Each patient demonstrated the same novel germ line mutation in exon 15 of the adenomatous polyposis coli (APC) gene and was successfully managed with sulindac after refusal to perform colectomy: a 23-year-old man with incidentally diagnosed gastric adenoma and fundic gland polyps underwent colonoscopy, and fewer than 100 colorectal polyps were found; a 48-year-old woman who happened to be the mother of the 23-year-old man also showed fewer than 100 colorectal polyps on colonoscopy. Genetic analysis revealed a novel frameshift mutation in exon 15 of the APC gene. The deletion of adenine-guanine with the insertion of thymine in c.3833-3834 resulted in the formation of stop codon 1,287 in both patients. The patients were treated with sulindac due to their refusal to undergo colectomy. The annual follow-up upper endoscopy and colonoscopy in the following 2 years revealed significant regression of the colorectal polyps in both patients.

Mesenteric panniculitis (MP) is non-specific inflammation of the adipose tissue that primarily involves the small bowel mesentery. Omental involvement has been rarely reported but we report a case of 25 years old woman with isolated lesser omental panniculitis. This patient was diagnosed by CT findings and recovered completely with conservative treatment. Invasive diagnostic methods or surgical exploration has been used to diagnose MP. However, all six reported cases of omental panniculitis including the current case showed a benign course; therefore, awareness of the CT findings is essential for the best diagnosis and management of omental panniculitis.

Upper gastrointestinal bleeding is a common condition and has various clinical courses and prognosis. End stage renal disease (ESRD) patients receiving hemodialysis have a high risk of vascular complications and increased risk of ischemic colitis. A 59-year-old male patient with ESRD receiving hemodialysis visited due to hematemesis. After admission, he showed recurrent hematemesis and hypovolemic shock. Upper esophagogastroduodenoscopy revealed gastric ulcer bleeding and endoscopic hemostasis was successfully performed. Blood transfusion and norepinephrine was administered for hypovolemic shock during initial 3 days. Ten days later, he exhibited hematochezia. Sigmoidoscopy revealed necrotic ischemic colitis in sigmoid colon and segmental colectomy was performed. However, recurrent leakage and ischemia were developed in colon as well as small bowel, and he finally died after 55 hospital days in spite of additional operations. Here, we report a case of peptic ulcer bleeding in patient with ESRD who suffered a severe form of ischemic colitis with transmural necrosis.

BACKGROUND/AIMS: The eradication rate of Helicobacter pylori (H. pylori) has been decreasing recently in Korea due to antibiotics resistance. The aim of this study was to investigate the trend of eradication rate and clinical factors affecting the eradication rate of H. pylori in the last 10 years in west Gyeonggi-do, Korea. METHODS: The trends of eradication rate of H. pylori, gender, age, concomitant mediations, and clinical factors were retrospectively evaluated in patients with H. pylori infection between 2006 and 2015 (n=2,485). RESULTS: The overall H. pylori eradication rate for the standard triple therapy was 82.5%. The annual eradication rates from 2006 to 2015 were 90%, 77.9%, 75.8%, 83.2%, 85.6%, 90.1%, 81.3%, 81.1%, 78.7%, and 78.8%, respectively, showing a significant decrement during the last five years (p < 0.001). Higher eradication rate was observed in males than in females (p < 0.001). Esomeprazole showed a higher eradication rate compared with pantoprazole between 2006 and 2010 (p < 0.022). Age and the use of probiotics and mucosal protective agents played no significant role in the H. pylori eradication rate. The overall eradication rate for bismuth-based quadruple therapy was 94.4%. CONCLUSIONS: The eradication rate of H. pylori over the last 10 years for first-line therapy ranged from 75.8 to 90.1%; the eradication rate for triple therapy has declined. However, the eradication rate for quadruple therapy has remained unchanged over the last 10 years.

BACKGROUND/AIMS: Peptic ulcer bleeding (PUB) is the most common cause of upper gastrointestinal bleeding in Korea but there has been no research done using big data. This study evaluates the optimal operational definition (OD) for big data research by analyzing clinical characteristics of PUB. METHODS: We reviewed the clinical characteristics of 92 patients with PUB confirmed on endoscopy in Wonkwang University Sanbon Hospital (January 2013 to December 2014). We calculated sensitivity and positive predictive value (PPV) to detect confirmed PUB patients using ODs developed by combining clinical features of patients with PUB. RESULTS: The mean patient age was 63 years. Men had higher prevalence of PUB than women. Bleeding gastric ulcer was proportionately common in the age range of 40s to 60s in men, while a significantly higher rate of bleeding occurred in women older than 70s. The rate of drug-induced ulcer was 28.2%, whereas the prevalence of Helicobacter pylori was 47.8%. Among the hospitalized patients with diagnostic code of PUB, we ruled out patients with endoscopic removal of gastric adenoma or peritonitis, and selected patients who had been administered intravenous proton pump inhibitor. The sensitivity in this setting was 82.6%, and PPV was 88.4%. CONCLUSIONS: PUB was more common in older patients, and there was a clear gender difference in gastric ulcer bleeding by age. With a proper OD using PUB diagnostic codes, we can identify true patients with sufficiently high sensitivity and PPV.
