Local recurrence at hepaticojejunostomy 9 years after resection of bile duct cancer with superficial flat spread.

We report a male patient aged 45 years, who in 1993 had been diagnosed as having middle bile duct cancer and had received a pancreatoduodenectomy. Histopathology showed a nodular tumor with the main lesion in the middle bile duct and superficial spreading in both proximal and distal directions (which was not observed macroscopically), and residual tumor in the epithelium of the cut edge near the liver. The patient underwent follow-up without postoperative adjuvant therapy.

Duodenum-preserving resection of the head of the pancreas--modified procedures and long-term results-.

Background/aims: Relief of chronic pancreatitis can be accomplished surgically or with medication. Surgical treatment of pancreatitis should preserve the endocrine and exocrine function of the pancreas. This paper details the results of our modified procedure for resecting the head of the pancreas.

[Transendoscopic microvascular Doppler sonography for the assessment of hemodynamics of esophageal and gastric varices].

The importance of unravel hemodynamics at the stomach and esophagus in patients with portal hypertension has been described for understanding pathophysiology and treatment of varices associated with portal hypertension. Microvascular Doppler sonogrlaphy (MF20) is a pulse Doppler method with 20 MHz which is able to measure velocity and direction of blood flow in microvessel. We invented transendoscopic microvascular Doppler sonography (EMDS) by connecting a tiny probe of one mm in diameter with an endoscopy.

[Clinical study on reoperation for recurrent pulmonary metastasis].

Ninety seven patients with metastatic lung tumors were treated surgically in our department. Second pulmonary resections were performed in 13 patients. They consists of 9 males and 4 females, their age ranged from 12 to 75 years old (average 54.
