Gastric lipoma is a typical benign submucosal tumor that is usually asymptomatic and is generally detected incidentally when performing gastroscopy. However, depending on its size and location, an atypical gastrointestinal lipoma can cause abdominal pain, diarrhea, constipation, intestinal obstruction, intussuception and life-threatening gastrointestinal bleeding. We report herein a case of gastric lipoma with bleeding in a 43-year-old man. The gastroscopy showed a $4{\times}4$ cm ulcero-fungating submucosal mass at the anterior wall of the gastric antrum. Laparoscopic gastric wedge resection was performed and the lesion was diagnosed as gastric lipoma.

Gastrointestinal (GI) bleeding is not a single disease but a symptom and clinical manifestation of a broad spectrum of conditions in the GI tract. According to its clinical presentation, GI bleeding can be classified into overt, occult, and obscure types. Additionally, it can be divided into upper and lower GI bleeding based on the Treitz ligament. Variable disease entities, including vascular lesions, polyps, neoplasms, inflammation such as Crohn's disease, and heterotopic pancreatic or gastric tissue, can cause GI bleeding. CT and conventional angiographies and nuclear scintigraphy are all radiologic imaging modalities that can be used to evaluate overt bleeding. For the work-up of occult GI bleeding, CT enterography (CTE) can be the first imaging modality. For CTE, an adequate bowel distention is critical for obtaining acceptable diagnostic performance as well as minimizing false positives and negatives. Meckel's scintigraphy can be complementarily useful in cases where the diagnosis of CTE is suboptimal. For the evaluation of obscured GI bleeding, various imaging modalities can be used based on clinical status and providers' preferences.

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.

Objectives The purpose of this study is to report a case of iron deficiency anemia in a child with repetitive bleeding in the upper gastrointestinal tract caused by Helicobacter pylori infection, and summarize review of a western literature. Methods A 13-year-old patient, who were suffering from iron deficiency anemia from repetitive bleeding in the upper gastrointestinal tract, was administered by Ikwiseungyang-tang gamibang (益胃升陽湯加味方) and Samchulgeonbitang (蔘出健脾湯). After several tests, we realized that an iron deficiency anemia was related to Helicobacter pylori. Results By herb medication, the patient's symptoms were alleviated. Conclusions Helicobacter pylori infection is one of the reasons of refractory iron-deficiency anemia which is unresponsiveness to oral iron therapy. We report the findings of herb medication along with summarization of a western literature.

Introduction: Unexpected serious and lethal drug interactions can be occurred by polypharmacy for treatment-resistant psychiatric disorders. We report a case who has suspected upper gastrointestinal bleeding after the combination of clozapine and buspirone. Case : A 69-year-old woman with DSM-IV schizophrenia who was admitted to our hospital had no previous medical problems. Findings on physical exam, laboratory values, EEG, and a magnetic reso-nance imaging scans were no abnormality, except for slightly low level of hemoglobin at admission. Because of aggravating anxiety symptom, a trial of buspirone was begun from 15mg, in addition to olanzapine 30mg. And then olanzapine was switched to clozapine due to her treatment-refractory his-tory and poor response on this admission. Moreover, At the admission 11 weeks later, after 4 weeks of starting buspirone and clozapine, she was placed on a regimen of clozapine 300mg and buspirone 60mg. At this point, she started to complaint nonspecific abdominal pain for 4 days and then hematemesis, melena and hypotension were developed suddenly with negative findings in gastroduodenoscopy. After stopping all medication, the suspected upper gastrointestinal bleeding was subsided. After the regimen was switched back to clozapine only, psychotic symptoms were improved without the recurrence of the adverse events. Conclusion : We concluded that the upper gastrointestinal bleeding in this case was attributed to the drug interaction with clozapine and buspirone, although the definite mechanism is not clear. The clini-cians should be very cautious to prescribe the combination of clozapine and buspirone due to a possible lethal adverse effect.

Background: The symptoms of small bowel malignancies are mild and frequently nonspecific, thus patients are often not diagnosed until the disease is at an advanced stage. Moreover, the lack of sufficient studies and available data on small bowel cancer makes diagnosis difficult, further delaying proper treatment for these patients. In fact, only a small number of published studies exist, and there are no studies specific to Thailand. Radiologic and endoscopic studies and findings may allow physicians to better understand the disease, leading to earlier diagnosis and improved patient outcomes. Objective: To retrospectively analyze the clinical, radiologic, and endoscopic characteristics of small bowel cancer patients in Thailand's Siriraj Hospital. Materials and Methods: This retrospective analysis included 185 adult patients (97 men, 88 women; mean age = $57.6{\pm}14.9$) with pathologically confirmed small bowel cancer diagnosed between January 2006 and December 2013. Clinical, radiologic, and endoscopic findings were collected and compared between each subtype of small bowel cancer. Results: Of the 185 patients analyzed, gastrointestinal stromal tumor (GIST) was the most common diagnosis (39.5%, n=73). Adenocarcinoma was the second most common (25.9%, n = 48), while lymphoma and all other types were identified in 24.3% (n = 45) and 10.3% (n = 19) of cases, respectively. The most common symptoms were weight loss (43.2%), abdominal pain (38.4%), and upper gastrointestinal bleeding (23.8%). Conclusions: Based on radiology and endoscopy, this study revealed upper gastrointestinal bleeding, an intra-abdominal mass, and a sub-epithelial mass as common symptoms of GIST. Obstruction and ulcerating/circumferential masses were findicative of adenocarcinoma, as revealed by radiology and endoscopy, respectively. Finally, no specific symptoms were related to lymphoma.

Gastrointestinal stromal tumors (GISTs) are the most common primary mesenchymal tumors of the digestive tract. They have been commonly observed in adults but have been rarely described in children. They arise typically from the intestinal wall and rarely in the mesentery, omentum, or retroperitoneum. GISTs originate from the interstitial cell of Cajal and are characterized by overexpression of the receptor tyrosine kinase c-kit. Up to 94% of these tumors express the CD117 on immunohistochemical stain. Surgery is the main modality of treatment for primary resectable GIST. Completely resectable GIST with low risk has excellent prognosis after primary surgical intervention, with over 90% of the 5-year survival. We report a case of 10-year-old girl presenting with an upper gastrointestinal bleeding caused by gastrointestinal stromal tumor.

Background/Aims: Gastric varices (GVs) are a major cause of upper gastrointestinal bleeding in patients with liver cirrhosis. The current treatments of choice are balloon-occluded retrograde transvenous obliteration (BRTO) and the placement of a transjugular intrahepatic portosystemic shunt (TIPS). We aimed to compare the efficacy and outcomes of these two methods for the management of GV bleeding. Methods: This retrospective study included consecutive patients who received BRTO (n=157) or TIPS (n=19) to control GV bleeding from January 2005 to December 2014 at a single tertiary hospital in Korea. The overall survival (OS), immediate bleeding control rate, rebleeding rate and complication rate were compared between patients in the BRTO and TIPS groups. Results: Patients in the BRTO group showed higher immediate bleeding control rates (p=0.059, odds ratio [OR]=4.72) and lower cumulative rebleeding rates (logrank p=0.060) than those in the TIPS group, although the difference failed to reach statistical significance. There were no significant differences in the rates of complications, including pleural effusion, aggravation of esophageal varices, portal hypertensive gastropathy, and portosystemic encephalopathy, although the rate of the progression of ascites was significantly higher in the BRTO group (p=0.02, OR=7.93). After adjusting for several confounding factors using a multivariate Cox analysis, the BRTO group had a significantly longer OS (adjusted hazard ratio [aHR]=0.44, p=0.01) and a longer rebleeding-free survival (aHR=0.34, p=0.001) than the TIPS group. Conclusions: BRTO provides better bleeding control, rebleeding-free survival, and OS than TIPS for patients with GV bleeding.

Gastric hemangioma in the neonatal period is a very rare cause of upper gastrointestinal bleeding. We present a case of hemangioma limited to the gastric cavity in a 10-day-old infant. A huge, erythematous mass with bleeding was observed on the lesser curvature side of the upper part of the stomach. Surgical resection was ruled out because the location of the lesion was too close to the gastroesophageal junction. Medical treatment with intravenous $H_2$ blockers, octreotide, packed red blood cell infusions, local epinephrine injection at the lesion site, application of hemoclip, and gel-form embolization of the left gastric artery did not significantly alter the transfusion requirement. Hemostasis was achieved with endoscopic argon plasma coagulation (APC). After two sessions of APC, complete removal of the lesion was achieved. APC was a simple, safe and effective tool for hemostasis and the ablation of gastric hemangioma without significant complications.

This is a rare case of a 73-year-old male patient who presented with hematochezia and was treated using transcatheter arterial embolization following upper gastrointestinal bleeding in the third portion of the duodenum. The cause of the bleeding was not found on gastrointestinal endoscopy and CT. On the third day of hospitalization, the hemoglobin level continued to decrease. A technetium-99m-labeled red blood cell scan revealed suspicious bleeding in the diverticulum of the third portion of the duodenum. Superior mesenteric artery angiography showed active bleeding from the posteroinferior pancreaticoduodenal artery, which was embolized with N-butyl cyanoacrylate. The patient was discharged on the seventh day after embolization without re-bleeding or complication. We report a rare case of a patient with active bleeding from a duodenal diverticulum that was difficult to diagnose using routine modalities. Herein, we report a rare case of a patient with active bleeding from a duodenal diverticulum that was difficult to diagnose using routine modalities. We also conducted a relavant literature review.
