The Dieulafoy's lesion is a rare cause of recurrent massive gastrointestinal bleeding in children. The bleeding results from an abnormally large submucosal artery that protrudes through a small mucosal defect. The lesion is commonly found on proximal stomach. Surgical intervention was believed to be the best treatment in the past, but recent advancement in endoscopy has made effective hemostasis possible. We report a case of a 9-year-old boy with underlying mycoplasma pneumonia with effusion who presented with massive upper gastrointestinal bleeding. Bleeding was controlled with endoscopic treatment by epinephrine and ethanol injection and the patient was successfully treated.

We report a 10-year-old girl with the blue rubber bleb nevus syndrome (BRBNS) who had chronic severe anemia caused by chronic occult bleeding in the gastrointestinal (GI) tract. The patient was admitted to the hospital frequently for recurrent pallor and fatigue since the age of 7 years. Gastroduodenoscopy and capsule endoscopy revealed multiple venous malformations with blood oozing in the stomach, small bowel and colon. The patient was treated by aggressive surgical resection of the 23 vascular malformations in the GI tract. The patient is well without anemia 15 months post surgery.

Gastric volvulus is an uncommon clinical entity. There are three types of gastric volvulus; organoaxial, mesenteroaxial and combined type. This condition can lead to a closed-loop obstruction or strangulation. Traditional surgical therapy for gastric volvulus is based on an open approach. Here we report a successful case of a patient with chronic gastric volvulus with a laparoscopic treatment. A 79-year-old woman came to the emergency department with epigastric pain accompanied by nausea for 2 weeks. Abdominal computed tomography revealed markedly distended stomach with transposition of gastroesophageal Junction and gastric antrum. Barium meal study revealed presence of the antrum was folded over 180 degrees that was located above gastroesophageal junction. We attempted an endoscopic reduction, but it was unsuccessful. The patient got laparoscopic anterior gastropexy. Based on our result, laparoscopic gastropexy can be considered as a good choice of the treatment for gastric volvulus.

Cryptococcus neoformans infection usually occurs in patients with advanced human immunodeficiency virus (HIV) infection or with a CD4 T lymphocyte count of <100 cells/µL. Pulmonary and central nervous system infections are the most frequently encountered forms of cryptococcosis; however, colonic cryptococcosis is uncommon. We describe the case of a 41-year-old antiretroviral-naïve man with HIV infection diagnosed eight years prior and intermittent diarrhea for 4 months who presented to the emergency department with a 1-day history of low-grade fever and confusion. Brain magnetic resonance imaging and cerebrospinal fluid analysis revealed normal results; however, he was diagnosed with Pneumocystis jirovecii pneumonia based on chest computed tomography and bronchoalveolar lavage analysis. Trimethoprim-sulfamethoxazole administration was initiated followed by antiretroviral treatment. Although his condition gradually improved, he developed fever and abdominal discomfort, and the diarrhea worsened. Endoscopy revealed a small ulcer in the distal transverse colon. Histopathological examination of a colon tissue sample revealed cryptococcal infection. He improved substantially during liposomal amphotericin B and fluconazole treatment. We encountered a rare case of colonic cryptococcosis that caused chronic diarrhea in a patient with advanced HIV infection. Colonic cryptococcosis should be considered when patients with acquired immune deficiency syndrome present with gastrointestinal symptoms.

The object of this study is to measure the transit time and passage rate of capsule endoscopy (CE) in the gastrointestinal tract in medium sized beagle dogs ($7{\sim}13\;kg$). Animals were divided into four groups: only capsule (group 1, n=10), capsule+water (group 2, n=10), mettoclopramide+capsule (group 3, n=10), metoclopramide +capsule+water (group 4, n=10). The capsule transit times through the stomach and small bowel were evaluated by radiography findings. Gastric transit time (GTT), small intestinal transit time (SITT) and complete passage rate were measured in four groups. GTT's for each group were as follows; $45{\pm}20\;min$ (group 1), $117{\pm}35\;min$ (group 2), $150{\pm}40\;min$ (group 3), and $154{\pm}65\;min$ (group 4), while SITT's were $75{\pm}20\;min$ (group 1), $195{\pm}55\;min$ (group 2), $70{\pm}15\;min$ (group 3), and $76{\pm}15\;min$ (group 4). The complete passage rates were 20% (group 1), 40% (group 2), 20% (group 3), 50% (group 4). In all groups, if CE could pass through the pylorus, it passed all small intestinal tracts within 8 hours (battery life). Administration of water helped CE to pass pylori, except in case of metoclopramide administration. These results indicate that CE could be an useful tool for examining gastrointestinal diseases in the veterinary medicine.

Purpose: Crohn's disease (CD) can involve any site of the gastrointestinal tract (GIT). However, the characteristics of upper GIT involvement in CD are unclear, especially in the Eastern pediatric population. This study aimed to estimate the prevalence of upper GIT involvement and identify the clinical features of Korean children with CD. Methods: This was a retrospective multicenter cohort study that included 52 pediatric patients with CD who underwent esophagogastroduodenoscopy and biopsy. The clinical symptoms and endoscopic and histologic features of the upper GIT were identified according to the presence or absence of upper gastrointestinal symptoms. Results: Among the 52 patients, upper GIT involvement was noted in 50.0% (26/52). The mean age at CD diagnosis was $14.1{\pm}2.1$ years. Gastric ulcer was the most common lesion (19.2%) found on upper GIT endoscopy, followed by duodenal ulcers (15.4%). Chronic inflammation was the most common histopathologic feature (75.0%), followed by gastric erosion (17.3%). Granuloma was found in 9.6% of patients. Helicobacter pylori infection was identified in 5.8% of patients. Endoscopic and histologic findings were not significantly different, but the mean values of erythrocyte sedimentation rate ($60.7{\pm}27.1$ vs. $43.0{\pm}27.6mm/h$, p=0.037) and C-reactive protein ($16.5{\pm}28.2$ vs. $6.62{\pm}13.4mg/dL$, p=0.014) were significantly different between patients with and without upper gastrointestinal CD symptoms. Conclusion: Upper GIT involvement was relatively common in pediatric patients with CD irrespective of upper gastrointestinal symptoms, and H. pylori infection was relatively uncommon. The results of this study should aid the establishment of regional guidelines for upper GIT examination.

Purpose: Familial Mediterranean fever (FMF) is an auto inflammatory disease characterized by periodic fever, synovitis and serositis. Patients may be admitted to gastroenterology units due to gastrointestinal symptoms. In this study; we aimed to analyze endoscopic findings and diagnostic utility of endoscopic procedure in children with FMF. Methods: Patient with FMF that was performed endoscopy for the gastrointestinal symptoms were included to the study (39 of 164 patients, 53 procedure). A control group was randomly designed as age and gender matched four endoscopic procedures per one endoscopic procedure of patients with FMF (n=212). Results: No different was found between the patients and control group in esophagogastroscopy findings. However, the diagnosis of gastrointestinal pathology was made by esophagogastroscopy in 46.2% patients. Colonoscopic examination revealed that the frequency of inflammatory bowel disease (IBD) was higher in undiagnosed patients compared to both the control group (50.0% vs. 6.9%, p<0.05, odds ratio [OR]:13.4 and 95% confidence inteval [95% CI]: 2.1-84.3) and the patients under colchicine treatment (50.0% vs. 8.3%, p<0.05, OR: 11 and 95% CI: 0.8-147.8). Colonoscopic procedure that was made after the diagnosis was found to provide contribution by 16.7% in determining the etiology of the additional symptoms. Conclusion: Patients with FMF may be admitted to pediatric gastroenterology outpatient clinic prior to diagnosis or during the follow-up period. The frequency of IBD is high in undiagnosed patients with FMF. Endoscopic procedures may be helpful in these patients for the diagnosis accompanying mucosal lesions.

Purpose: To understand the epidemiology of different upper gastrointestinal (UGI) tract related abnormalities through endoscopic data analysis. Materials and Methods: A retrospective study of three years from January 2009 to December 2011 was conducted with data from endoscopic surveillance of upper GI tract problems, collected from the Gastroenterology Unit, Osmania General Hospital, Hyderabad. MS excel and Medcalc software (comparison of proportions) were used for data analysis. Results: A total of 10,029 (6,468 in males and 3,561 in females) endoscopies were performed during this three-year period. The male to female ratio was 1.8:1. Overall, ~30% of endoscopies evaluated showed patients with acid peptic disorders, 13.6% with vascular-related abnormalities, 10.6% showed structural abnormalities, followed by 6.3% with malignancies. Burden of malignancies was mostly observed in the older age group (60-69 years). Esophageal cancer cases decreased (p=0.0001) whereas stomach cancers increased over this period (p=0.0345). We also observed an increased incidence of acid peptic disease (APD) (p=0.0036) and gastroesophageal reflux disease (GERD) (p=0.0002) cases during this period. Conclusions: Endoscopic diagnosis is useful for early detection of UGI anomalies and helpful for physicians to manage and treat varied kinds of UGI disorders. Analysis of data revealed changing trends in the incidence of various pathologies of the UGI tract. Functional dyspepsia and GERD definitely reduce the quality of life of the individual. The role of our diverse dietary habits and lifestyle associated with these problems have not yet been established, though there have been reports on the effect of coffee, spicy food, wheat-based diet, screening of UGI pathologies along with collection of complete personal and medical history details, can h elp in correlating the patients' condition with various aspects of lifestyle and diet.

A 14-year-old, castrated male, domestic shorthair cat was referred for gastrointestinal (GI) signs, including nausea, regurgitation, anorexia, and weight loss. Abdominal ultrasonography revealed thickening of the wall of the gastric and proximal duodenum, moderately enlarged mesenteric lymph nodes, and coarse echotexture of the splenic parenchyma. The results of the feline leukemia virus test were positive. Based on gastrointestinal endoscopic characteristics and histopathological examinations, low-grade alimentary lymphoma was identified in multiple regions of the gastrointestinal tract. The patient was treated with oral prednisolone and chlorambucil chemotherapy, and the clinical signs resolved gradually. During serial follow-up, ultrasonographic findings demonstrated decreases in the duodenal wall thickness and size of the abdominal lymph nodes over a period of 550 days. Survival time was 886 days with prednisolone and chlorambucil chemotherapy. This report describes clinical features, imaging findings, endoscopic characteristics, histopathological features, and long-term management with chlorambucil chemotherapy in a case of feline low-grade alimentary lymphoma.

We report here a case of a gastrointestinal stromal tumor (GIST) in the stomach that was diagnosed by endoscopic ultrasound-guided fine needle aspiration cytology (EUS-FNA). A 67 year old male patient underwent regular check-ups for five years due to the presence of a submucosal tumor that was found in the fundus of the stomach incidentally. EUS-FNA was performed to evaluate the tumor, which had increased in size from 1 cm to 2.8cm. A cytologic smear revealed cohesive sheets or clusters of spindle cells with elongated nuclei. Immunohistochemical staining revealed a strong positive reaction for c-kit and CD34, without any reaction for smooth muscle actin and Ki-67. Therefore, a diagnosis of GIST was made.
