We present a new intraarterial infusion chemotherapy technique for the treatment of inoperable cancer in the body and tail of the pancreas. The spleen was embolized at its hilum with coils to infuse an anti-tumor agent selectively into the pancreatic parenchyma and a catheter was placed into the splenic artery and connected to the reservoir. 99mTc-macroaggregated albumin+diethylenetriaminepenta-acetic acid (MAA+DTPA) was injected into the reservoir and the body and tail of the pancreas were visualized on the image. For inoperable cancer in the body and tail of the pancreas, splenic artery embolization followed by the placement of a catheter into the splenic artery can deliver a highly concentrated anti-tumor agent to the tumor.

A case of abscess caused by a penetrating duodenal ulcer.

A case of abscess caused by a penetrating duodenal ulcer in a 34 year-old female patient is presented. She had a past history of duodenal ulcer and presented with a low grade fever which had persisted for 1 month. Abdominal ultrasound confirmed a hypoechoic mass and computed tomography revealed a low density area in the posterior side of the hepatoduodenal ligament. The common bile duct and portal vein were compressed. Mild peripheral enhancement was detected. Laparotomy was performed and an abscess in the posterior side of the hepatoduodenal ligament was confirmed. The abscess was firmly adhered to the lesser curvature side of the bulbus and a penetrating duodenal ulcer scar was noted. In conclusion, this report describes a rare event where penetrating duodenal ulcer formed an abscess with only mild complaints.

Treatment of spontaneous ruptured hepatocellular carcinoma.

BACKGROUND/AIMS: Spontaneous rupture with bleeding is a potentially life-threatening complication of hepatocellular carcinoma (HCC). We review our experience with treatments of ruptured HCC. METHODOLOGY: Between January 1988 and December 1997, 18 patients with ruptured HCC were admitted. The patients were divided into 4 groups according to the treatment type of ruptured HCC. Group 1 consisted of 10 patients treated by transarterial embolization (TAE) followed by elective hepatectomy. Group 2 consisted of 2 patients treated by only TAE. Group 3 consisted of 3 patients treated by emergency operation. Group 4 consisted of 3 patients who could not be treated by TAE or surgery. RESULTS: In Group 1, 4 of the 10 patients died; 3 from recurrent HCC and 1 from cerebral hemorrhage, and hospital mortality was absent. The 1-year survival rate was 87.5%. In Group 2, both patients recovered sufficiently well to be discharged. The 1-year survival rate was 50%. In Groups 3 and 4, hospital mortality rate was 100%. CONCLUSIONS: TAE followed by elective hepatectomy was an effective treatment in patients with ruptured HCC.

Adrenal metastasis from hepatocellular carcinoma (HCC): report of 3 cases.

Although autopsy reports show that the adrenal gland is the second most common organ of hematogeneous metastasis from hepatocellular carcinoma (HCC), paradoxically there is found to be a very scarce number of the adrenal metastasis in clinical practice. We have recently experienced rare patients with right adrenal metastasis from HCC. Case 1: A 51 year-old man with a 5-year history of chronic hepatitis was admitted with hematemesis to Nippon Medical School Hospital. CT revealed a main tumor associated with a few daughter tumors in the hepatic posterior segment and in addition another tumor located between the right hepatic lobe and right kidney. The diagnosis of HCC with a right adrenal gland metastasis was made, and hepatectomy and right adrenalectomy was performed. Twenty months after operation he was alive and free of disease. Case 2: A 78 year-old man underwent resection of the lateral segment of the left hepatic lobe for HCC. Twelve months later, recurrent foci in the residual liver were found and those were treated with transarterial embolization (TAE). Right adrenal metastasis was found on CT 26 months after hepatectomy. TAE was done for the hepatic recurrent tumors and adrenal metastasis. Twelve months after, he survived in good condition. Case 3: A 47 year-old man presented with liver cirrhosis with a long history. He was diagnosed as having HCC with multiple intrahepatic metastases and was treated with TAE 4 times. Follow-up CT revealed right adrenal metastasis. TAE was done for hepatic recurrent tumor and right adrenal metastasis. Three months later the patient died of liver failure.

Experience with intraarterial infusion of styrene maleic acid neocarzinostatin (SMANCS)-lipiodol in pancreatic cancer.

A 54 year-old man was admitted to our hospital and diagnosed with inoperable cancer in the body and tail of the pancreas. The spleen was embolized at its hilum with a coil to infuse an anti-tumor agent selectively into the pancreatic parenchyma and transcatheter intraarterial infusion (TAI) of styrene maleic acid neocarzinostatin (SMANCS)-Lipiodol, 3 mg, was performed. The computed tomography (CT) scan taken immediately after TAI revealed the incorporation of SMANCS-Lipiodol into the site of the pancreatic tail. At 2 weeks, a small amount of SMANCS-Lipiodol remained and clearness of the tumor margin was lacking in the pancreatic tail, but no remarkable change was noted in the body. As for the laboratory data, pancreatic enzyme level was not elevated immediately after TAI. At 2 weeks, tumor markers showed improvement in CEA (3.9-->2.6 ng/ml) and Elastase 1 (370-->230 ng/ml), but little change was seen in CA 19-9 (1600 U/ml: no change) and DUPAN-2 (730-->740 U/ml). In pancreatic cancer, SMANCS-Lipiodol could be infused from the splenic artery into the pancreatic parenchyma by the splenic arterial embolization.

Endoscopic variceal ligation (EVL) combined with partial splenic embolization (PSE).

BACKGROUND/AIMS: The effectiveness of reducing the recurrence rate of esophageal varices by combining partial splenic embolization (PSE) with endoscopic variceal ligation (EVL) was investigated. METHODOLOGY: Patients with complete eradication of esophageal varices were collected as study cases with the following results: 31 cases with PSE and EVL (PSE+EVL group), 25 cases with EVL alone (EVL group), and 33 cases with EIS alone (EIS group). The cumulative recurrence rates were obtained by observing new varices. RESULTS: The cumulative recurrence rates at 6 months were 21.1% in the PSE+EVL group, 58.1% in the EVL group and 32.5% in the EIS group. Those at 1 year were 37.0%, 70.7% and 50.2%, respectively, and those at 2 years were 58.1%, 80.4% and 73.0%, respectively. For all 3 time periods, recurrence rates of the PSE+EVL group were significantly lower than those of the EVL group (p=0.042). Cumulative rates in the PSE+EVL group tended to be lower than those in the EIS group. Further analysis was made on the comparative recurrence rates of the 3 groups, according to Child's classification. The cumulative recurrence rates in Child A cases did not significantly differ between the 3 groups. Cumulative rates in Child B cases were significantly lower in the PSE+EVL group than in the EVL group (p=0.032), and those in the PSE+EVL group tended to be lower than those in the EIS group. These trends were observed between the PSE+EVL group and the EVL group in Child C cases, while cumulative rates did not show differences between the PSE+EVL group and the EIS group. CONCLUSIONS: It was inferred that PSE-combined EVL therapy is a very effective therapy for achieving long-term complete eradication of esophageal varices.

Correlation between angiographic features of esophageal varices and recurrence after endoscopic treatment.

BACKGROUND/AIMS: In spite of complete eradication of esophageal varices by endoscopic treatment, early recurrence or rebleeding is very common. Recurrence following endoscopic treatment for esophageal varices is considered to be affected by various clinical factors. However, it is unclear what parameters have significant impact on recurrence. We focused on angiographic features to investigate the correlation of the hemodynamic status to recurrence rate in esophageal varices. METHODOLOGY: Forty-five Japanese cirrhotic patients with risky esophageal varices were treated by Endoscopic Injection Sclerotherapy (EIS) after examination of selective left gastric arteriography or venography. We analyzed the correlation of the angiographic features before EIS and the cumulative recurrence rate using the log-rang test. RESULTS: Features of the angiographies were classified into 2 types: Extending type (E-type): the image of the esophageal varices extended from the pericardiac venous plexus to the middle or upper esophagus; Disappearing type (D-type): the image disappeared in the portion of the abdominal esophagus. Of the 45 patients in this study, 20 (44.4%) fell into the E-type category and, 24 (53.3%) fell into the D-type category. The Cumulative variceal recurrence rate of the E-type was significantly lower than that of the D-type (log-rank test, p = 0.011). As regards background characteristics, no significant differences were found between the 2 groups. CONCLUSIONS: Angiographic features classified into the E- and D-type categories by pre-treatment varicerography are a useful predictor of variceal recurrence after EIS.

Synchronous carcinoma of the gallbladder in a patient with intrahepatic bile duct carcinoma.

An 83-year-old woman, diagnosed as having cholelithiasis, was admitted to the Department of Surgery, Nippon Medical School, with right hypochondrial pain. Ultrasonography and computed tomography revealed a mass in the gallbladder fundus and a hypovascular tumor in the anterior segment of the liver. Magnetic resonance imaging showed stenosis of the intrahepatic bile duct and dilatation of its proximal portion. She was diagnosed as having intrahepatic bile duct carcinoma combined with gallbladder carcinoma. At laparotomy, there was evidence of multiple peritoneal metastases and intraoperative histological examination of the gallbladder tumor revealed adenocarcinoma. Accordingly, only cholecystectomy and needle biopsy of the liver tumor was performed. Histological examination of the gallbladder revealed papillary adenocarcinoma invading the muscularis propria with medullary growth or intermediate stroma. There was no microvessel invasion, no perineural invasion and no lymph node involvement. On the other hand, the liver tumor was a cholangiocarcinoma with a well-differentiated tubular pattern. Therefore, this was a rare case of synchronous carcinoma of the gallbladder associated with intrahepatic bile duct carcinoma.

Colonic varices ruptured via drainage catheter after extended right hepatectomy.

Extended right hepatectomy was performed on a 69-year-old woman with bile duct carcinoma of the hepatic hilum. Three weeks after the operation, an abscess was detected at the resected surface and a drainage catheter was inserted. The patient was discharged with the drainage catheter in place and followed-up at a local hospital. Three months later, the drainage catheter was removed. Bleeding immediately occurred through the fistula, and fistulography revealed varices. Angiography demonstrated right colonic varices, and the fistula was embolized with coils. There was no further bleeding. In conclusion, colonic varices that ruptured via a fistula of a drainage catheter were embolized through the fistula. Embolization of the fistula was useful in stopping the bleeding.
