Bleeding that recur or continues after hospital admission for an acutely bleeding peptic ulcer is the single most important factor adversely affecting prognosis. The endoscopic findings of stigmata of recent hemorrhage such as active bleeding, a visible vessel or fresh blood clots in peptic ulcer indicate relatively high rebleeding risk. 30 patients with stigmata of recent hemorrhage in bleeding peptic ulcers were treated by endoscopic alcohol injection therapy during the 3-year period from August 1989 to July 1992. 30 cases included 24 gastric ulcers, 4 duodenal ulcers, and 2 stomal ulcers. 8 of these were actively bleeding at the time of endoscopy and non-bleeding visible vessels were identified in 15 patients and fresh blood clots were present in 7. 12 of total 30 cases had rebleeding or continuous bleeding. 3 of 8 with active bleeding, 5 of 15 with non-bleeding bisible vessels, and 4 of 7 with fresh blood clots had rebleeding. Emergency operations were done in 4 cases. There was no complication such as perforation and mortality. We think that this modality of endoscopic hemostasis is safe and simple, but further randomized controlled trials will be needed to evaluate the efficacy of hemostasis by endoscopic alcohol injection therapy.

Neuroendocrine carcinoma of the colon is a very rare entity. However, this type of tumor is known to have aggressive progression and poor prognosis. A case of a 72-year-old male is presented in this report. A 3 cm sized tumor was found on the rectum with multiple liver metastases. The pathological findings including a positive immunohistochemical staining for synaptophysin and cytokeratin done with colonoscopic biopsy and liver biopsy confirmed the tumor as a neuroendocrine carcinoma. The nomenclature and definition of this disease still remains somewhat unclear, and not a small population of this disease may thus have been misdiagnosed and treated as other less aggressive entities, such as carcinoid tumor. The necessity to make an accurate differential diagnosis in such cases is thus emphasized because of different treatments and clinical courses. For its rarity and clinical significance, we report this case with a review of the literatures.

BACKGROUND/AIMS: The incidence of gastroesophageal reflux disease (GERD) is increasing in Korea. The aim of this study was to evaluate the relationship between GERD symptoms and dietary factors in Korea. METHODS: From January 2007 to April 2008, 162 subjects were enrolled (81 in GERD group and 81 in control group). They were asked to complete the questionnaires about GERD symptoms and dietary habits. The symptom severity score was recorded by visual analogue scale. RESULTS: Subjects with overweight or obesity had an increased risk for GERD (OR, 2.52; 95% CI, 1.18-5.39). Irregular dietary intake was one of the risk factors for GERD (OR, 2.33; 95% CI, 1.11-4.89). Acid regurgitation was the most suffering (2.85 +/- 2.95 by visual analogue scale) and frequent reflux-related symptom (57.5%) in GERD. Noodles (OR, 1.22; 95% CI, 1.12-1.34), spicy foods (OR, 1.09; 95% CI, 1.02-1.16), fatty meals (OR, 1.20; 95% CI, 1.09-1.33), sweets (OR, 1.42; 95% CI, 1.00-2.02), alcohol (OR, 1.16; 95% CI, 1.03-1.31), breads (OR, 1.17; 95% CI, 1.01-1.34), carbonated drinks (OR, 1.69; 95% CI, 1.04-2.74) and caffeinated drinks (OR,1.41; 95% CI, 1.15-1.73) were associated with symptom aggravation in GERD. Among the investigated noodles, ramen (instant noodle) caused reflux-related symptoms most frequently (52.4%). CONCLUSIONS: We found that noodles, spicy foods, fatty meals, sweets, alcohol, breads, carbonated drinks and caffeinated drinks were associated with reflux-related symptoms.

Background/Aims: Few studies have investigated the long-term outcomes of endoscopic resection for early gastric cancer (EGC) in very elderly patients. The aim of this study was to determine the appropriate treatment strategy and identify the risk factors for mortality in these patients. Methods: Patients with EGC who underwent endoscopic resection from 2006 to 2017 were iden-tified using National Health Insurance Data and divided into three age groups: very elderly (≥85 years), elderly (65 to 84 years), and non-elderly (≤64 years). Their long- and short-term outcomes were compared in the three age groups, and the survival in the groups was compared with that in the control group, matched by age and sex. We also evaluated the risk factors for long- and short-term outcomes. Results: A total of 8,426 patients were included in our study: 118 very elderly, 4,583 elderly, and 3,725 non-elderly. The overall survival and cancer-specific survival rates were significantly lower in the very elderly group than in the elderly and the non-elderly groups. Congestive heart failure was negatively associated with cancer-specific survival. A significantly decreased risk for mortality was observed in all groups (p<0.001). The very elderly group had significantly higher readmission and mortality rates within 3 months of endoscopic resection than the non-elderly and elderly groups. Furthermore, the cerebrovascular disease was associated with mortality within 3 months after endoscopic resection. Conclusions Endoscopic resection for EGC can be helpful for very elderly patients, and it may play a role in achieving overall survival comparable to that of the control group.

Granular cell tumor (GCT), first described by Abrikossoff in 1926, is relatively uncommon, usually benign and solitary neoplasm. The most frequently involved organs include the tongue, skin, breast, and digestive tract. Until now, less than 200 cases of GCTs of the digestive tract have been reported in the esophagus, and less than 50 cases in the large intestine, stomach, biliary tract in the world. Only less than 20 cases of GCT of the rectum have been reported in the world. It is believed that there have been no reported cases of GCT of the rectum in Korea. Recently, the incidence of granular cell tumor has been slowly rising since endoscopy has been used more commonly as a diagnostic tool. We report a case of granular cell tumor in the rectum in a 49-year-old male patient, which was confirmed by microscopic examination after colonoscopic polypectomy.

The Korean Society of Neurogastroenterology and Motility first published guidelines for chronic constipation in 2005 and was updated in 2011. Although the guidelines were updated using evidence-based process, they lacked multidisciplinary participation and did not include a diagnostic approach for chronic constipation. This article includes guidelines for diagnosis and treatment of chronic constipation to realistically fit the situation in Korea and to be applicable to clinical practice. The guideline development was based upon the adaptation method because research evidence was limited in Korea, and an organized multidisciplinary group carried out systematical literature review and series of evidence-based evaluations. Six guidelines were selected using the Appraisal of Guidelines for Research & Evaluation (AGREE) II process. A total 37 recommendations were adopted, including 4 concerning the definition and risk factors of chronic constipation, 8 regarding diagnoses, and 25 regarding treatments. The guidelines are intended to help primary physicians and general health professionals in clinical practice in Korea, to provide the principles of medical treatment to medical students, residents, and other healthcare professionals, and to help patients for choosing medical services based on the information. These guidelines will be updated and revised periodically to reflect new diagnostic and therapeutic methods.

BACKGROUND/AIMS: Recently, early detection and treatment of early colon cancer (ECC) has increased, and the concept of de novo carcinogenesis of colon cancer was introduced. However there were few studies in Korea. So we tried to find the incidence of ECC and the possibility of de novo colon cancer (DCC) in Korea. METHODS: From Jun 1995 to Jun 2003, 3072 patients who first treated as colon cancer at Samsung Medical Center were enrolled. We selected ECC by medical record review, and pathologic slides and endoscopic photos were reviewed to evaluate the underlying tissue of cancer focus and morphologic characteristics of ECCs. ECC was defined as the cancer confined to mucosa or submucosa, and DCC was defined as the cancer lesser than 1 cm but had no adenoma component. RESULTS: The 192 patients (6.3%) had 196 cases of ECC. The ratio of mucosal and submucosal (SM) cancers was 36.7%:63.3%. The protruded type was the most frequent type (82.1%). The depressed type was the smallest (12.9+/-6.3 mm), in size and 100% showed and SM involvement. It has significantly higher rate of the cancer without underlying adenoma component (57.1%, p<0.001). The DCC were 6 cases and all were SM cancer and had 3 cases of protruded and depressed type each other. CONCLUSIONS: The most common shape of ECC was protruded type. However, depressed type was smaller and had higher rate of SM involvment and no adenoma component around the cancers. And we found some of DCC although the frequency was very low.
