Although hemangiomas are common vascular tumors that can occur anywhere in the body, they seldom involve the gastrointestinal tract. Hemangiomas of the gastrointestinal tract in infants and children are rare benign vascular tumors that most commonly present with gastrointestinal bleeding. We describe here the case of 2-year-old boy with intestinal bleeding caused by a large jejunal cavernous hemangioma, which was treated by laparoscopy-assisted resection of the affected portion of the jejunum.

Peptic ulcer bleeding is a common complication of peptic ulcer disease and the most common cause of upper gastrointestinal bleeding. Despite advances in drug usage and endoscopic modalities, no significant improvement is observed in the mortality rate of bleeding ulcers. The purpose of this review is to discuss various endoscopic hemostatic methods to treat peptic ulcer bleeding. Endoscopic hemostatic techniques can be classified into injection, mechanical, electrocoagulation, hemostatic powder, and endoscopic Doppler-guided hemostatic therapies (the last mentioned being a newly developed technique). Endoscopic hemostasis can be performed as mono or combination therapy using the aforementioned methods. Endoscopic hemostasis is the most important treatment for patients with peptic ulcer bleeding. Endoscopists should consider the treatment approach for peptic ulcer bleeding based on patient characteristics, the size and shape of the lesion, the endoscopist's expertise, and the resources and circumstances at each hospital. Follow-up studies are needed to evaluate the efficacy of newly developed hemostatic powder therapy and endoscopic Doppler-guided hemostasis.

Percutaneous endoscopic gastrostomy (PEG) is a common method for providing long-term enteral nutrition to patients. PEG tube placement and removal are relatively safe; generally, a PEG tube can be removed using gentle traction, and excessive bleeding is rare. The over-the-scope clip system is a new device that can be used for gastrointestinal hemostasis and for closing gastrointestinal fistulae. In the present case, a 68-year-old male patient had to remove the PEG tube because of persistent leakage around the PEG tube. Although it was gently removed using traction, incessant bleeding continued, with a Rockall score of 5 points, even after hemocoagulation was attempted. An over-the-scope clip device was used to achieve hemostasis and fistula closure.

Gastrointestinal (GI) hemangiomas are relatively rare benign vascular tumors. The choice of an appropriate diagnostic method depends on patient age, anatomic location, and presenting symptoms. However, GI hemangiomas are not a common suspected cause of GI bleeding in children because of their rarity. Based on medical history, laboratory results, and imaging study findings, the patient could be treated with either medication or surgery. Herein, we report 3 cases of GI hemangioma found in the small bowel, rectum, and GI tract (multiple hemangiomas). Better knowledge and understanding of GI hemangioma could help reduce the delayed diagnosis rate and prevent inappropriate management. Although rare, GI hemangiomas should be considered in the differential diagnosis of GI bleeding.

Adverse events such as hemoptysis and gastrointestinal hemorrhage during tyrosine kinase inhibitor treatment are relatively rare, but the severity of the bleeding can be higher than other common adverse events. It is necessary to educate patients about its possibility so that they can be found early. In this case report of radioiodine refractory thyroid cancer patient, hemoptysis and gastrointestinal bleeding has occurred following lenvatinib administration. Drug interruption and dose modification and dose interruption were required in addition to management for bleeding itself. It is necessary to confirm the high risk of bleeding before the administration of tyrosine kinase inhibitors, and to appropriately control the follow-up interval and drug dosage accordingly.

Purpose: The aims of our study were to evaluate the blood urea nitrogen to creatinine ratio (BUN/Cr ratio) for distinguishing between an upper and lower gastrointestinal bleeding (GIB), and differentiating between the two most common causes of upper gastrointestinal bleeding (UGIB) presenting with melena in children. Methods: Retrospective data of patients with GIB presenting with melena were analyzed. The data from 60 cases were reviewed including demographics, laboratory findings, diagnostic modalities and results, treatments, and transfusions. Results: Among the 60 cases, UGIB and lower gastrointestinal bleeding (LGIB) were found in 35 cases (58.3%) and 14 cases (23.3%), respectively. The two common causes of UGIB were varices (37.1%), and peptic ulcer diseases (PUD) (31.4%). The BUN/Cr ratio of 30 or greater was higher in UGIB than LGIB (odds ratio [OR], 6.9; 95% confidence interval [95% CI], 1.3-37.2). In UGIB, the BUN/Cr ratio of the varices group was higher than that of the PUD group (p=0.015). The OR for the BUN/Cr ratio appeared as 1.2 per unit increase in the varices group than the PUD group (95% CI, 1.03-1.3). There was no difference between the PUD group and Meckel's diverticulum group. Conclusion: The BUN/Cr ratio was not uneven in differentiating UGIB from LGIB of children with melena in our study. This suggests that BUN/Cr ratio should be interpreted carefully.

Peptic ulcer bleeding (PUB) is the most common cause of non-variceal upper gastrointestinal bleeding, and its frequency has been declining over the past decades. However, mortality from PUB persists, and it is still a serious challenge in clinical practice. Although endoscopic intervention is the basic treatment modality for PUB, pharmacological therapy is an important adjunct. The emergence of proton pump inhibitors (PPIs) enables maintenance of intragastric pH >6, which greatly helps in the treatment of PUB. Continuous intravenous infusion of high-dose PPI reduces the re-bleeding rate, thereby helping avoid additional surgery in patients with high-risk stigmata. Moreover, administration of PPIs prior to endoscopy may reduce the need for additional endoscopic intervention. Recently introduced gastric acid suppressants, such as potassium-competitive acid blockers, have shown promising results in further treatment of PUB.

위장관 출혈은 단일 질환이 아니라 광범위한 위장 질환의 증상 및 임상적 발현이다. 임상적 양상에 따라 명백한 출혈, 잠재 출혈, 원인 불명 출혈로 나눌 수 있으며, 출혈 위치에 따라 Treiz 인대를 기준으로 상부 또는 하부 위장관 출혈로 분류할 수 있다. 혈관 질환, 용종, 종양, 크론병, 이소성 췌장 및 이소성 위조직 등 다양한 질환이 위장관 출혈을 일으킬 수 있다. 명백한 출혈을 위한 영상 검사기법은 CT 혈관조영술, 고식적 혈관조영술 및 핵의학적 검사 등이 사용된다. 잠재 위장관 출혈을 평가하기 위한 영상검사로는 CT 소장조영술이 주로 사용되며, 위장관을 적절히 팽창해서 영상을 획득해야 위음성 혹은 위양성을 최소화하여 진단능을 높일 수 있다. CT 소장조영술에서 진단이 확실하지 않은 경우, Meckel scan이 보완적으로 사용될 수 있다. 원인 불명 위장관 출혈에 대한 검사는 임상 양상과 임상의 혹은 영상의학과 의사의 선호도에 따라 다양한 검사가 시행될 수 있으며, 이에 대한 추가적인 연구가 필요하다.

Upper gastrointestinal (GI) bleeding (UGIB) is the most common GI emergency, and it is associated with significant morbidity and mortality. Early identification of low-risk patients suitable for outpatient management has the potential to reduce unnecessary costs, and prompt triage of high-risk patients could allow appropriate intervention and minimize morbidity and mortality. Several risk-scoring systems have been developed to predict the outcomes of UGIB. As each scoring system measures different primary outcome variables, appropriate risk scores must be implemented in clinical practice. The Glasgow-Blatchford score (GBS) should be used to predict the need for interventions such as blood transfusion or endoscopic or surgical treatment. Patients with GBS ${\leq}1$ have a low likelihood of adverse outcomes and can be considered for early discharge. The Rockall score was externally validated and is widely used for prediction of mortality. The recently developed AIMS65 score is easy to calculate and was proposed to predict in-hospital mortality. The Forrest classification is based on endoscopic findings and can be used to stratify patients into high- and low-risk categories in terms of rebleeding and thus is useful in predicting the need for endoscopic hemostasis. Early risk stratification is critical in the management of UGIB and may improve patient outcome and reduce unnecessary health care costs through standardization of care.

Introduction: This case report addressed the effect of Korean medicine treatments on a patient with hemorrhagic anemia due to lower gastrointestinal bleeding. Case report: An 83-year-old male with lower gastrointestinal bleeding was treated with Korean medicine, including the herbal medication Subi-jeon. We evaluated the improvements of symptoms by hemoglobin levels and numbers of transfusions. From the 6^th day of taking the herbal medicine to discharge, a hemoglobin level of 7 g/dL or higher was maintained and the patient did not require blood transfusion. Conclusions: This clinical case study suggests that Subi-jeon might be effective in cases of hematosis of lower gastrointestinal bleeding.
