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.

Gastrointestinal (GI) bleeding is one of the most common conditions among patients visiting emergency departments in Korea. GI bleeding is divided into upper and lower GI bleeding, according to the bleeding site. GI bleeding is also divided into overt and occult GI bleeding based on bleeding characteristics. In addition, obscure GI bleeding refers to recurrent or persistent GI bleeding from a source that cannot be identified after esophagogastroduodenoscopy or colonoscopy. The small intestine is the largest part of the alimentary tract. It extends from the pylorus to the cecum. The small intestine is difficult to access owing to its long length. Moreover, it is not fixed to the abdominal cavity. When hemorrhage occurs in the small intestine, the source cannot be found in many cases because of the characteristics of the small intestine. In practice, small-intestinal bleeding accounts for most of the obscure GI bleeding. Therefore, in this review, we introduce and describe systemic approaches and examination methods, including video capsule endoscopy and balloon enteroscopy, that can be performed in patients with suspected small bowel bleeding in clinical practice.

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.

Juvenile polyps are the most common types of polyps in children, and patients usually present with lower gastrointestinal (GI) bleeding as the predominant symptom. These lesions, which are referred to as hamartomas, usually measure approximately 2 cm in size and are benign tumors located mainly in the rectum and sigmoid colon. The most common symptom of a juvenile polyp is mild intermittent rectal bleeding. It is rare for anemic patients because the amount of blood loss is small and often not diagnosed immediately. We present the case of a 6-year-old girl with a juvenile polyp in the distal transverse colon, who developed hypovolemic shock due to massive lower GI bleeding. Pediatricians must perform colonoscopy for thorough evaluation of polyps, because their location and size can vary and they can cause massive bleeding.

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.

In Crohn's disease, mild gastrointestinal bleeding often occurs; however massive gastrointestinal hemorrhage, which can have a dramatic effect on a patient's vital sign, is rare. This could result in potentially life-threatening complications, which can lead to death. Massive hemorrhagic Crohn's disease is not well known and for this reason, they are a diagnostic and therapeutic challenge. Various diagnostic and therapeutic methods are currently being developed and used. The surgical method is often used only as a last measure since this approach has the risk of serious complications that may endanger patients. However, if massive bleeding continues even after all therapeutic methods are used, the surgical method must be implemented. In this case, all therapeutic methods were found to be ineffective; therefore, surgery was used as a last option. Ultimately, the surgical method was found to be successfully used to treat life-threatening hemorrhagic Crohn's disease.

Although Dieulafoy lesion can occur in any part of the gastrointestinal tract, its occurrence in the rectum is rare. Rectal Dieulafoy lesions have been associated with advanced age, renal failure, burns, liver transplantation and cirrhosis. Here, we report on a case of massive bleeding from a rectal Dieulafoy lesion after lung decortication surgery in a 57-year-old male patient with alcoholic cirrhosis. Although rare, a rectal Dieulafoy lesion should be included in the differential diagnosis of massive lower gastrointestinal bleeding in a patient with cirrhosis.

Objective: To investigate the diagnostic yield of contrast-enhanced computed tomography (CT) in Crohn's disease (CD) patients presenting with acute severe lower gastrointestinal bleeding (LGIB), and the role of CT in predicting the risk of rebleeding. Materials and Methods: A consecutive series of 110 CD patients presenting with acute severe LGIB between 2005 and 2016 were analyzed. Among them, 86 patients who had undergone contrast-enhanced CT constituted the study cohort. The diagnostic yield of CT for detecting contrast extravasation was obtained for the entire cohort and compared between different CT techniques. In a subgroup of 62 patients who had undergone CT enterography (CTE) and showed a negative result for extravasation on CTE, the association between various clinical and CTE parameters and the risk of rebleeding during subsequent follow-up was investigated using Cox regression analysis. Results: The diagnostic yield of CT was 10.5% (9 of 86 patients). The yield did not significantly differ between single-phase and multiphase examinations (p > 0.999), or between non-enterographic CT and CTE (p = 0.388). Extensive CD (adjusted hazard ratio [HR], 3.27; 95% confidence interval [CI], 1.09-9.80; p = 0.034) and bowel wall-to-artery enhancement ratio (adjusted HR, 2.81; 95% CI, 1.21-6.54; p = 0.016) were significantly independently associated with increased rebleeding risks, whereas anti-tumor necrosis factor-${\alpha}$ therapy after the bleeding independently decreased the risk of rebleeding (adjusted HR, 0.26; 95% CI, 0.07-0.95; p = 0.041). Conclusion: The diagnostic yield of contrast-enhanced CT was not high in CD patients presenting with acute severe LGIB. Nevertheless, even a negative CTE may be beneficial as it can help predict the risk of later rebleeding.

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.
