[Tissue concentration of 5-FU following pre-operative administration of FT-207].
Forty patients with gastric cancer and 30 patients with colon cancer were administered FT-207 prior to the operation. The relation between a total dose (4-88g) and tissue concentration of 5-FU was investigated and the following results were obtained. (5-FU concentration was measured with the method of Gas chromatography mas fragmentography) 1) The relation between total doses of FT-207 (x) and concentration of 5-FU in the tissue (y) was demonstrated by the formula: y = 0.00317x + 0.025 (gastric cancer) r = 0.519, p = 0.0001 y = 0.0019x + 0.043 (colon cancer) r = 0.641, p = 0.0001 2) In most of the patients with rectal cancer who received radiation therapy prior to the operation, 5-FU concentration in the tissue was extremely low. 3) 5-FU concentration showed no difference between the normal and metastatic lymph nodes, or among the lymph node groups. Administration methods (oral intake or suppository) had no influence on the concentration of 5-FU. 4) Among the organs, 5-FU concentration was higher in the following orders: liver, normal mucosa, lymph node, tumor, normal serosa. 5) In five autopsy cases, 5-FU concentration of the tissue show a great difference among them, and some cases showed 10 times as high concentration as others in the tissue of every organ.

Injection sclerotherapy of esophageal varices for patients undergoing emergency and elective surgery.
From October 1977 to September 1981, 68 patients with esophageal varices (30 emergency cases of bleeding and 38 elective cases) were treated by injecting 5% ethanolamine oleate into varices, using an esophagofiberscope. Esophageal bleeding was successfully controlled in 29 of 30 patients who had emergency surgery. None of the 38 patients who underwent elective operation had bleeding after treatment. When recurrence occurred 1 or 2 years after treatment, the same procedure was repeated. Pleuritis occurred in one of the patients who had emergency surgery, and bleeding (300 to 400 ml) from the esophagocardial junction occurred in two patients who underwent elective operation. These patients were treatment conservatively.

Choledocholithotomy by Yag laser with a choledochofiberscope: case reports of two patients.
The Neodymium-Yag laser was successfully used with a choledochofiberscope for choledocholithotomy in two patients. The bile duct stones were crushed with the Yag laser and removed or pushed into the duodenum without causing any injury. This procedure is highly recommended for treatment of some patients with bile duct stones.

Resection combined with intraoperative radiation therapy (IORT) for stage IV (TNM) gallbladder carcinoma.
From October 1976 to May, 1990, a total of 86 patients with stage IV (TNM) gallbladder cancer were treated at Tsukuba University Hospital. Twenty-seven of the 86 patients underwent tumor resection; 43 patients received palliative surgery. The remaining 16 were too advanced to have surgery. Of 27 patients who had tumor resection, 9 had resection alone, 17 had intraoperative radiation therapy (IORT) +/- postoperative external radiotherapy (ERT), and 1 had postoperative ERT. The procedures used were: extended right hepatic lobectomy plus hepaticobiliary resection (HBR) (n = 2), hepatic segmentectomy (SIVb, SV) plus HBR (n = 9), hepatic segmentectomy (SIV, V, VI) with HBR (n = 1), hepatic segmentectomy (SIV, V) plus HBR with pancreaticoduodenectomy (PD) (n = 3), PD plus HBR (n = 1), cholecystectomy with wedge resection of the gallbladder fossa plus HBR (n = 3), and cholecystectomy plus HBR (n = 3), and cholecystectomy (n = 4). Regional lymph node dissections were performed in every patient and 17 of 27 patients underwent additional resections of adjacent organs such as the stomach, duodenum, colon, and abdominal wall. A single dose of 20-30 Gy was delivered intraoperatively for 17 patients. A mean total dose of 36.4 Gy (1.8/fraction) was added to IORT for 10 patients. The three-year cumulative survival rate was 10.1% for resection plus IORT but 0% for resection alone. The longest survivor is alive and well at 3 years and 3 patients are alive 16, 13, and 4 months after tumor resection followed by IORT plus ERT.

Reevaluation of spiral CT cholangiography: basic considerations and reliability for detecting choledocholithiasis in 80 patients.
PURPOSE: The purpose of this work was to reevaluate the characteristics and diagnostic accuracy of spiral CT cholangiography (CTC) for detecting biliary calculi. METHOD: Spiral CTC was performed in 133 patients with suspected biliary or pancreatic diseases. All source images were reviewed by two radiologists who were unaware of final diagnoses. Attenuation values of bile were correlated with biochemical data and visualization of anatomic detail. The statistical measures in detecting the presence of choledocholithiasis were calculated in 80 patients with confirmed diagnoses. RESULTS: Statistically significant correlations were found between the degree of biliary enhancement and both serum bilirubin and alkaline phosphatase levels. Of the 80 patients, 18 (23%) had choledocholithiasis and 62 did not. Observers diagnosed them with a sensitivity of 89% and a specificity of 98%. A mild adverse reaction to contrast material was observed in three (2.3%) patients. CONCLUSION: Spiral CTC is a reliable, noninvasive, and accessible technique for detecting choledocholithiasis.

Definitive proton beam radiation therapy for inoperable gastric cancer: a report of two cases.
Proton beam radiation therapy using 250 MeV protons was carried out on two patients with early gastric cancer (T1, N0, M0). One patient was an 85-year-old man with early gastric cancer of type IIa + IIc. The other one was a 70 year old man with early gastric cancer of type IIc. In both cases histological examination of biopsy specimens showed differentiated adenocarcinoma; distant metastasis was not found by other examinations. Both patients were considered inoperable due to their poor cardiac and/or respiratory functions. Therefore, it was decided to treat them by definitive proton irradiation, delivering total doses of 86 Gy and 83 Gy, respectively. In both patients, skin erythema that did not require any special treatment was found in the irradiation field. Hematobiological examinations did not show any abnormality. Although endoscopic examination at two years after irradiation in the former case and at seven months in the latter case showed persistent gastric ulcer at the site of the cancerous lesions, cancer cells were not found histologically. Therefore, we concluded that proton irradiation therapy was useful for inoperable early gastric cancers.

Schmidt syndrome due to idiopathic accessory nerve paralysis.
A patient with Schmidt syndrome due to idiopathic accessory neuropathy has had paralysis of soft palate and larynx as well as trapezius and sternocleidomastoid muscles, reflecting involvement of cranial and spinal roots, respectively. In addition to vocal cord paralysis on the laryngoscopy, videofluoroscopy confirmed diminished mobility of the soft palate. Electrodiagnosis showed accessory neuropathy at the proximal segment. Furthermore, the accessory nerve innervated not only upper but also middle and lower portions of the trapezius muscles.

Prevention of postoperative pericardial adhesions with a defibrinogenating agent.
Pericardial adhesions pose a major problem during re-operative cardiac surgical procedures. The purpose of this study was to determine the effect of Batroxobin, a fibrinogen depleting agent, on the incidence of experimental pericardial adhesions. Twenty-four rabbits were divided into 3 groups of 8 rabbits each and pericardial mesothelial injury was induced by abrasion. Group A included rabbits receiving no further treatment, Group B included rabbits receiving intrapericardial injection of Ringer's solution, and Group C included rabbits receiving intrapericardial injection of Batroxobin. Three weeks after surgery, the incidence of adhesions in Groups B and C was compared with that in Group A. Pericardial adhesions found in 80% of the rabbits in Groups A and B. However, only 14% of the rabbits in Group C had pericardial adhesions (p < 0.05). Our findings demonstrated that intrapericardial Batroxobin reduced the incidence of pericardial adhesions in an animal model.
