Laparoscopic treatment of intestinal intussusception in Peutz-Jeghers syndrome: case report and review of literature.

A 47-year-old woman presented with an abdominal mass and nausea. Abdominal ultrasound and computed tomography (CT) showed a sausage-shaped mass with invagination. One polyp that appeared to exceed 3 cm was found in the sigmoid colon.

A case of primary small intestinal cancer diagnosed by laparoscopy.

The patient was a 61-year-old female who developed ileus. Physical findings showed abdominal distension but peritoneal irritation signs were not observed. After the conservative treatment by the ileus tube, encircling stenosis was observed in the jejunum at about 50 cm on the anal side from the Treitz ligament on contrast radiography of the small intestine through the ileus tube.

Effect of pouched reconstruction after total gastrectomy on ERCP and ENBD--report of two cases.

Endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic nasobiliary drainage (ENBD) are well known to be useful but these procedures are rarely indicated in patients after total gastrectomy, because the endoscopic approach is more difficult in the patients with standard reconstructions such as Roux-en-y esophagojejunostomy after total gastrectomy. Gastric replacement with various enteric reservoirs after gastrectomy has been used to improve the postprandial symptoms and nutrition of patients after total gastrectomy. We have been performing jejunal pouch double tract reconstruction (JPD) after gastrectomy and the patients' postoperative course has been satisfactory.

Undifferentiated spindle and giant cell carcinoma of the common bile duct.

Undifferentiated spindle and giant cell carcinoma of the common bile duct has not been reported previously. We present here a case of 71-year-old man with the undifferentiated spindle and giant cell carcinoma of the common bile duct, including immunohistochemical findings. A nodular infiltrating tumor was located at the lower portion of the extrahepatic bile duct, and measured 1.

Thrombospondin-1 expression as a prognostic predictor of pancreatic ductal carcinoma.

Pancreatic cancer is a malignant tumor with an extremely poor prognosis. Thrombospondin-1 (TSP-1) was suggested to be a potential regulator of tumor growth and metastasis. We examined TSP-1 expression in 77 cases of invasive ductal adenocarcinoma of the pancreas, and analyzed the correlation between the TSP-1 expression pattern and clinicopathological features in pancreatic cancer.
