Henoch-Schonlein purpura (HSP) is a vasculitis involving small vessels of skin, joints, gastrointestinal (GI) tract, and kidneys. The patients typically show palpable purpura with one or more characteristic manifestations including abdominal pain, hematuria or arthritis. HSP shows gastrointestinal symptoms in 50~85% of patients, and in 14~40% of patients GI symptoms precede purpuric rash which makes the diagnosis of HSP difficult. We present a case of Henoch-Schonlein purpura with GI bleeding, septic shock by ileal microperforation, small bowel obstruction as a result of ileal stricture and psoas muscle abscess.

Lymphangioma is a benign vascular lesion with characteristics of subepithelial tumor which can proliferate in the lymphatic system. Lymphangioma of the small-bowel mesentery is rare, having been reported in less than 2% of all lymphangiomas. Lymphangioma does not require any specific treatment because it is absolutely a benign tumor. However, surgical exploration is rarely required for cases with disease-related symptoms or complications, or for those misdiagnosed as a malignant lesion. We recently experienced a case of mesenteric cavernous lymphangomas in a 53-year-old female who was misdiagnosed as having a liposarcoma. The final diagnosis was confirmed by a pathologic examination of the specimen that was obtained via laparoscopic exploration. Herein, we report a very rare case of mesenteric cavernous lymphangioma along with a brief review of relevant literature.

We report a case of a 61-year-old man who presented with a cough and abdominal discomfort. CT scan of the chest showed two lesions across both lungs, and an abdominal CT scan revealed multiple hypodense lesions in the spleen with cystic lesions on the splenic hilum. Upper gastrointestinal tract endoscopy found creamy yellowish discharge through a fistula between the stomach and splenic hilum. Under fluoroscopic guidance, forceps was inserted into the fistula tract, and forcep biopsy was done. The pathology was consistent with tuberculosis, and a nine-month anti-tuberculosis medication regimen was started. Imaging performed three months after finishing medication indicated improvement of splenic lesions, and the gastro-splenic tract was sealed off. This case is a very rare clinical example of secondary splenic tuberculosis with a gastro-splenic fistula formation in an immunocompetent patient.

Vasculopathy is rarely reported in neurofibromatosis type 1, but when it occurs it primarily involves the aorta and its main branches. Among vasculopathies, aneurysmal dilatation is the most common form. Although several case reports concerning aneurysms or pseudoaneurysms of visceral arteries in neurofibromatosis type 1 patients have been reported, there are no reports describing gastroduodenal artery aneurysms associated with neurofibromatosis type 1. We experienced a case of life-threatening duodenal ulcer bleeding from a ruptured gastroduodenal artery aneurysm associated with neurofibromatosis type 1. We treated our patient by transarterial embolization after initial endoscopic hemostasis. To our knowledge, this is the first reported case of its type. High levels of suspicion and prompt diagnosis are required to select appropriate treatment options for patients with neurofibromatosis type 1 experiencing upper gastrointestinal bleeding. Embolization of the involved arteries should be considered an essential treatment over endoscopic hemostasis alone to achieve complete hemostasis and to prevent rebleeding.

Duodenal diverticula are common, but perforated duodenal diverticulum is rare. Because of the disease rarity, there is no standard management protocol for perforated duodenal diverticulum. To properly manage this rare complication, a clear preoperative diagnosis and clinical disease severity assessment are important. An abdomino-pelvic CT is an unquestionably crucial diagnostic tool. Perforation is considered a surgical emergency, although conservative treatment based on fasting and broad-spectrum antibiotics may be offered in some selected cases. Herein, we report two cases of perforated duodenal diverticulum, one case managed with surgical treatment and one with conservative treatment.

The development of curvilinear EUS has enabled EUS-guided fine-needle aspiration of intra-abdominal mass lesions. With the introduction of interventional EUS, this technology has undergone several modifications in order to be applied to clinical medicine. One of the potential uses of interventional EUS is the EUS-guided local therapy of pancreatic tumors. Various treatment modalities such as fine-needle injection, radiofrequency ablation, photodynamic therapy, laser ablation, and brachytherapy have been tried under EUS guidance. Some of these modalities are being applied clinically. These methods for EUS-guided local therapy of pancreatic tumors will be reviewed in this article.

Pancreatic adenocarcinoma is one of the fatalist malignancies. A large proportion of patients are diagnosed with unresectable stage pancreatic cancer at the time of presentation. Gemcitabine is a standard chemotherapeutic agent since 1997, but survival benefit is not satisfactory. Recent clinical study proved that several new combination chemotherapy regimens are superior to gemcitabine single chemotherapy and extended overall survival. However, its prognosis still remains grim. Current research is taking a multidirectional approach in the hope of developing more effective treatments. This article reviews the major clinical trial data that is the basis for the current chemotherapy regimens used as first- and second-line treatments for advanced pancreatic adenocarcinoma. This article also reviews the current ongoing clinical trials, which include the use of molecular targeting agents and immune therapies.
