Brunner's gland hamartomas are rare tumors of duodenum, they are often discovered incidentally during esophagogastroduodenoscopy or upper gastrointestinal series. These tumors arise mainly in the duodenal bulb and can present with gastrointestinal hemorrhage and intestinal obstruction. Most of Brunner's gland hamartomas are located within the range of the standard esophagogastroduodenoscope. However, they are rarely located below the third portion of duodenum. As well known, the small intestine, including the 4th portion of duodenum, jejunum, and ileum, is relatively inaccessible with routine endoscopy. Thus, the diagnosis of Brunner's gland hamartoma in these area can be delayed up to several months after onset of symptoms. We report a case of Brunner's gland hamartoma which was located in the fourth portion of the duodenum and presented as obscure gastrointestinal hemorrhage. Radiologic, surgical, and pathologic appearances are presented.

Amyloidosis is a disorder characterized by extracellular deposition of amyloid in various tissues and organs. Gastrointestinal manifestations including gastroparesis, constipation, malabsorption, intestinal pseudo-obstruction, and bleeding are common. GI bleeding is a rare initial symptom which can be fatal in some cases. Absence of systemic symptoms and nonspecific endoscopic findings in amyloidosis may make diagnosis difficult. Therefore, amyloidosis-induced GI bleeding should be considered in patients with an obscure hemorrhage. Recently, we experienced a 65-year-old woman who presented with massive hematochezia as a manifestations of amyloidosis. Colonoscopy and SMA angiography showed massive bleeding in the small and large intestine. Colonoscopic biopsy established amyloidosis. We report this case with a review of the relevant literatures.

Eosinophilic enteritis is a rare disease characterized by tissue eosinophilia, which can affect different layers of bowel wall. Normally, the disease presents as colicky abdominal pain, and rarely as an acute intestinal obstruction or perforation. In this paper, we report a case of eosinophilic enteritis, hitherto unreported, presenting as an ileal obstruction, and followed by jejunal bleeding, which was visualized by capsule endoscopy. A 62-year-old man received a 15 cm single segmental ileal resection at a point 50 cm from the IC valve due to symptoms of obstruction, which were diagnosed as eosinophilic enteritis. Seventeen days after operation, intermittent abdominal pain occurred again, and subsided upon 30 mg per day treatment with prednisolone. Fourteen days after this pain attack, the patient exhibited hematochezia, in spite of continuous prednisolone treatment. Capsule endoscopy showed fresh blood spurting from the mid-to-distal jejunum, in the absence of any mass or ulcer. This hematochezia rapidly disappeared following a high-dose steroid injection, suggesting it was a manifestation of jejunal eosinophilic enteritis.

The clinical manifestations of intestinal tuberculosis are non-specific. But, abdominal pain, low grade fever, weight loss, anorexia, and diarrhea are major symptoms of intestinal tuberculosis. Massive bleeding has been reported as a rare manifestation of intestinal tuberculosis. Massive hematochezia from intestinal tuberculosis has rarely been reported in the medical literature. Also, most of them were treated with anti-tuberculosis medication only or with surgery. We treated a case of intestinal tuberculosis presenting massive hematochezia with colonoscopic coagulation therapy and anti-tuberculosis medication. Here, we report a Korean man who presented with massive hematochezia from ileal tuberculosis and treated by endoscopic coagulation therapy.

BACKGROUND/AIMS: Little information is available on the rate and predictive factors of rebleeding of unknown cause, which is very important in deciding further investigations on obscure-overt gastrointestinal bleeding. The aim of this study was to evaluate the rebleeding rate and related factors in obscure-overt gastrointestinal bleeding patients who revealed normal gastroscopic and colonoscopic findings. METHODS: A total of 69 patients with negative first-line gastroscopy and colonoscopy were enrolled in this study as obscure-overt gastrointestinal bleeding cases. The relationships between rebleeding and clinical characteristics were analyzed retrospectively. RESULTS: The causes of obscure-overt gastrointestinal bleeding were confirmed in 30 cases among the 69 cases. Small bowel tumors (14 cases) were the most common cause, followed by vascular lesions (6 cases). The mean follow-up period was 28 months and rebleeding was noticed in 19 patients (27.5%). Among these rebleeding patients, 14 cases (73.7%) occurred within 6 months. The past experience of previous bleeding was significantly related with rebleeding (p=0.0009). CONCLUSIONS: Close observation and detailed investigations are needed for obscure-overt gastrointestinal bleeding patients with bleeding history, especially during 6 months follow-up.

To analyze the clinical features and prognosis of ulcerative colitis(UC)complicated with acute massive lower gastrointestinal bleeding(LGIB). Methods Eleven patients hospitalized in Peking Union Medical College Hospital from January 2006 to December 2017 for treatment of UC,suffering from acute massive LGIB,were enrolled and descriptively analyzed. Results The proportion of UC patients with acute massive LGIB was 0.7% among all 1486 UC patients hospitalized during the study period.The disease was moderately or severely active in these 11 patients,among whom 9 patients(81.8%)had chronic relapsing pancolitis.Cytomegalovirus infection was present in 5 patients,among whom 4 patients received antiviral treatments.All the 11 patients received treatments including food and water fasting,rehydration,blood transfusion,and use of somatostatin.Four patients received emergency surgical treatment after the first episode of massive bleeding,and 3 of them suffered from re-bleeding after the surgery.Among the remaining seven patients,two underwent emergency total colectomy+subtotal rectectomy+ileostomy and three received elective total resection of colon and rectum or total colectomy+subtotal rectectomy+ileostomy.Thus,9 patients underwent emergency surgery,1 patient did not receive surgey during follow-up,and 1 patient was lost to follow-up. Conclusions Acute massive LGIB is a manifestation of active UC and can be associated with poor prognosis.Optimized perioperative management is important for improving the outcomes of such patients.

The stomach is the most frequent site of gastrointestinal stromal tumor (GIST). The common clinical manifestation of GIST are melena and hematochezia caused by gastointestinal bleeding. However, hemoperitoneum due to GIST rupture is a very rare condition. We describe a 33-year-old man with gastric GIST causing hemoperitoneum. A preoperative CT scan demonstrated large amount of fluid collection and extraluminal mass lesion in gastric antral area. He underwent an emergent laparotomy. The antral mass was polypoid shaped and showed ruptured focus. We performed a distal gastrectomy. The tumor was revealed as GIST with intermediate malignant risk by pathologic examination. The patient had an uneventful postoperative course and remains well.

Meckel's diverticulum is an embryonic derivative of the omphalomesenteric duct and the most commonly encountered congenital anomaly of the gastrointestinal tract. Its incidence records about 2%. Among them, only 5% are symptomatic with complications-bleeding, intestinal obstruction, inflammation, and perforation. In particular, bleeding is a common complication and has always been caused by an ulceration of the ileal mucosa adjacent to the acid-producing ectopic mucosa in a Meckel's diverticulum. Wireless capsule endoscopy is a new method enabling non-invasive diagnostic endoscopy of the entire small intestine. We experienced a case of Meckel's diverticulum detected by wireless capsule endoscopy in a 34 year-old man who presented with chronic obscure gastrointestinal bleeding.

The majority of patients with scleroderma have gastrointestinal involvement, and a few experience gastrointestinal hemorrhage, however, gastrointestinal hemorrhage due to Mallory-Weiss syndrome is very rare. We report upon a 24-year-old pregnant woman with scleroderma who had gastrointestinal hemorrhage due to Mallory-Weiss syndrome.
