[A case of gastrointestinal stromal tumor of the duodenum with a huge abscess].

A 36-year-old man admitted for upper abdominal pain and fever. Enhanced abdominal computed tomography showed a cystic tumor with an air fluid level, measuring 140mm in size, along the side of the first and second portions of the duodenum. The common bile duct, portal vein, and proper hepatic artery were displaced by the tumor.

[A case of advanced rectal cancer responding to neoadjuvant chemotherapy with CPT-11, 5-FU and l-LV after coronary artery bypass graft].

A 75-year-old man was referred to our hospital with a diagnosis of lower rectal cancer. Unstable angina attack occurred after admission and cardiac angiography revealed stenosis of three coronary arteries which were treated by percutaneous transluminal coronary angioplasty unsuccessfully. Coronary artery bypass graft was performed after colostomy.

[A long-term survival case after resection for umbilical metastasis from gastric cancer treated with weekly paclitaxel].

We report a patient with umbilical metastasis of gastric cancer (Sister Mary Joseph' s nodule) who has been treated by weekly paclitaxel for 16 months after resection of an umbilical tumor. A 61-year-old man who underwent total gastrectomy for cytology-positive advanced gastric cancer in March 2002 and received TS-1 after surgery for 2 years, complained of abdominal pain in May 2004. Physical examination and computed tomography showed an umbilical nodule about 20 mm in diameter.

Hepatic resection for colorectal metastases in the caudate lobe of the liver.

Although hepatic resections for colorectal metastases have become established procedures, there is still only a small number of reports of hepatic resections for such metastases in the caudate lobe. From 1993 to 2001, seven patients underwent eight hepatic resections for colorectal metastases in the caudate lobe at our department. The patients were five men and two women, and their ages were from 53 to 73 years.

Hepatectomy following transarterial chemotherapy for a metastasis in the caudate lobe.

We describe a solitary liver metastasis in the caudate lobe from a colon cancer treated with a hepatic resection following transarterial chemotherapy. A 73-year-old male was admitted with a complaint of melena. The findings from endoscopic examination of the colon showed a type 3 cancer at the hepatic flexure.

Direct retroperitoneal open drainage via a long posterior oblique incision for infected necrotizing pancreatitis: report of three cases.

Although several surgical approaches have been advocated for patients with infected necrotizing pancreatitis, there is still a high incidence of morbidity and mortality. We used a new approach of direct retroperitoneal open drainage after various other treatments, for three patients with necrotizing pancreatitis and extended infection with multiple-organ failure. Long oblique incisions were made from the root of the 12th rib to the anterior superior spina iliaca on the left or right side of the back, or both, to approach the retroperitoneal area of infected necrosis.

A giant retention cyst of the pancreas (cystic dilatation of dorsal pancreatic duct) associated with pancreas divisum.

We describe a rare case of pancreas divisum associated with a giant retention cyst (cystic dilatation of the dorsal pancreatic duct), presumably formed following obstruction of the minor papilla. The patient was treated by pancreatico(cysto)jejunostomy. A 50-year-old man was admitted with complaints of increasing upper abdominal distension and body weight loss.
