[Multifocal angiosarcoma of the gastrointestinal tract:a case report].

An 80-year-old man presented to our hospital with complaints of tarry stool and shortness of breath. A blood test confirmed marked anemia. On abdominal contrast-enhanced computed tomography, neither hemorrhagic lesions nor tumorous lesions could be pointed out.

[Neuroendocrine tumor of the terminal ileum observed by magnifying endoscopy with narrow-band imaging: a case report].

We report the case of an 88-year-old woman with localized intestinal obstruction caused by a midgut neuroendocrine tumor (NET) without endocrine symptoms. She was referred to our hospital for lower abdominal pain. Abdominal enhanced computed tomography revealed a thickened wall in the terminal ileum with dilated small bowel and multiple hepatic metastases upstream.

[Obstructive colitis following the ingestion of laxatives during bowel preparation for colonoscopy: a report of two cases].

The first case of obstructive colitis (OC) was observed in a 71-year-old man who presented to our hospital complaining of frank blood in the stool. After receiving a laxative for bowel preparation, he complained of lower abdominal pain. Colonoscopy revealed a circumferential tumor at the rectosigmoid junction.

A novel endoscopic papillectomy after a pancreatic stent placement above the pancreatic duct orifice: inside pancreatic stenting papillectomy.

Background: Although pancreatic stenting is recommended for the prevention of postprocedure pancreatitis during endoscopic papillectomy (EP), in some patients it is technically difficult to perform postprocedure insertion of a pancreatic stent after endoscopic resection.

Goals: This study assessed the feasibility of a novel EP for the purpose of reliable post-EP pancreatic stenting.

Study: We conducted a prospective pilot study involving 10 consecutive patients with tumor of the major duodenal papilla.

Use of antithrombin and thrombomodulin in the management of disseminated intravascular coagulation in patients with acute cholangitis.

Background/aims: To evaluate the usefulness and safety of treating disseminated intravascular coagulation (DIC) complicating cholangitis primarily with antithrombin (AT) and thrombomodulin (rTM).

Methods: A DIC treatment algorithm was determined on the basis of plasma AT III levels at the time of DIC diagnosis and DIC score changes on treatment day 3. Laboratory data and DIC scores were assessed prospectively at 2-day intervals.

Late Migration of Covered Metal Stent to the Stomach Through a Spontaneous Choledochoduodenal Fistula in a Patient With Malignant Biliary Obstruction.

We report a case in which a spontaneous choledochoduodenal fistula occurred after biliary covered self-expanding metal stent (SEMS) placement and a late transfistula migration of the stent in a patient with malignant distal biliary obstruction. A partially covered WallFlex biliary stent (Boston Scientific) was appropriately implanted in the common bile duct. Subsequently the patient received chemotherapy with gemcitabine.

[Gemcitabine therapy for unresectable pancreatic cancer in elderly patients].

We evaluated the therapeutic effect of gemcitabine (GEM) therapy in 153 unresectable pancreatic cancer (UPC) patients, divided into younger patients (under 65), early-stage elderly patients (age 65-74) and advanced-stage elderly patients (age 75 and over). Among those patients who received only best supportive care (BSC), the most common reasons to be selected for BSC were family requests in the advanced-stage elderly patients, and poor general condition in the rest. Among the patients who received GEM therapy, there were no significant differences in response rate, or adverse events including the rate of dose reduction, postponement or cessation of GEM administration due to toxicity.
