[Show abstract][Hide abstract] ABSTRACT: Sorafenib is the standard systemic therapy for patients with advanced hepatocellular carcinoma (HCC). We aimed to assess the efficacy and safety of sorafenib therapy in very elderly patients aged 80 years and older with advanced HCC.
In a retrospective multicenter study in Japan, we reviewed 185 patients (median age, 71 years; 82% male; 95% Child-Pugh class A) with advanced HCC who received sorafenib therapy. Data were compared between 24 (13%) patients aged 80 years and older and 161 (87%) patients aged less than 80 years. We used propensity score matching to adjust for differences between the two groups.
Median overall survival was 10.6 months in all patients: 11.7 months in patients aged 80 years and older and 10.5 months in those aged less than 80 years. There were no significant differences in overall survival, tumor response, and frequency and severity of drug-related adverse events between patients aged 80 years and older and those aged less than 80 years in both the entire study cohort and the propensity-matched cohort.
Sorafenib may be effective and well tolerated, even in patients with advanced HCC who are aged 80 years and older, as well as those aged less than 80 years.
[Show abstract][Hide abstract] ABSTRACT: The purpose of this retrospective study was to investigate the incidence of contrast-induced nephropathy (CIN) caused by transarterial chemoembolisation (TACE) in patients with hepatocellular carcinoma (HCC).
One hundred forty-one patients treated between 2005 and 2008 undergoing 305 consecutive sessions of TACE were enrolled. CIN was defined as an increase in the serum creatinine level of more than 0.5 mg/dl or more than 25 % from baseline within 3 days after TACE without any other identifiable cause of acute kidney injury.
CIN by the present definition was observed after 2.6 % of the TACE sessions. No patient showed clinical signs or symptoms of acute renal failure, or required haemodialysis. None of the patients with an estimated glomerular filtration rate of <60 ml/min/1.73 m(2) developed CIN.
The present study suggests that TACE is a relatively safe procedure in terms of the risk of CIN under vigorous periprocedural hydration and that the incidence of CIN is comparable to that of AKI associated with intravenous CM administration.
• CIN would be lower for non-coronary arterial intervention than for coronary intervention. • The present study suggests that the CIN rates following TACE are low. • The incidence of CIN is comparable to that after intravenous CM administration.

After inserting a Sengstaken-Blakemore tube, we performed endoscopic variceal ligation for ruptured esophageal varices. On the third day of admission, she developed septicemia and necrotizing fasciitis caused by Bacillus cereus. She was successfully treated with early debridement of both lower extremities and intravenous treatment with vancomycin, ciprofloxacin, and clindamycin. Although B. cereus is an attenuate bacterium, it can occasionally cause fatal infection in immuno-compromised individuals, such as those with liver cirrhosis.
[Show abstract][Hide abstract] ABSTRACT: Double-balloon enteroscope (DBE)-assisted endoscopic retrograde cholangiopancreatography (ERCP) is an effective endoscopic approach for pancreatobiliary disorders in patients with altered gastrointestinal anatomy. Endoscopic interventions via DBE in these postoperative settings remain difficult because of the lack of an elevator and the use of extra-long ERCP accessories. Here, we report the usefulness of direct cholangioscopy with an ultra-slim gastroscope during DBE-assisted ERCP. Three patients with choledocholithiasis in postoperative settings (two patients after Billroth II gastrojejunostomy and one patient after Roux-en-Y gastrojejunostomy) were treated. DBE was used to gain access to the papilla under carbon dioxide insufflation, and endoscopic sphincterotomy was performed with a conventional sphincterotome. For direct cholangioscopy, the enteroscope was exchanged for an ultra-slim gastroscope through an incision in the overtube, which was inserted directly into the bile duct. Direct cholangioscopy was used to extract retained bile duct stones in two cases and to confirm the complete clearance of stones in one case. Bile duct stones were eliminated with a 5-Fr basket catheter under direct visual control. No adverse events were noted in any of the three cases. Direct cholangioscopy with an ultra-slim gastroscope facilitates subsequent treatment within the bile duct. This procedure represents another potential option during DBE-assisted ERCP.

[Show abstract][Hide abstract] ABSTRACT: A 68-year-old man had been followed up since March, 1997 because of a cystic tumor of the pancreas head. The patient developed obstructive jaundice and was admitted to our hospital in June, 2007. The tumor size on CT scan had increased from 3.6 cm to 5.9 cm during the 10-year period. After endoscopic biliary drainage, pancreatoduodenectomy was performed. Pathological diagnosis of the resected specimen was serous cystadenoma. Serous cystadenoma of the pancreas is known as a benign tumor with indolent progression and is likely to be symptomatic if the tumor size exceeds 4 cm. However, biliary obstruction is a rare complication of serous cystadenoma. We report this rare case here with references to the literature.

[Show abstract][Hide abstract] ABSTRACT: A 62-year-old woman presented with a markedly increased serum ALP level of skeletal origin during a regular follow-up of chronic hepatitis C. Serum calcium, phosphorus, and intact-PTH levels were normal and bone turnover markers were increased. Her generalized bone density was diffusely increased. These findings were consistent with hepatitis C-associated osteosclerosis (HCAO). She underwent cholecystectomy, as gallbladder cancer was suspected; however, histopathological findings demonstrated xanthogranulomatous cholecystitis. After cholecystectomy, serum ALP level and bone turnover markers were gradually decreased. This may indicate the existence of a novel osteogenic factor in the gallbladder in HCAO.

[Show abstract][Hide abstract] ABSTRACT: A 65-year-old man was admitted because of epigastralgia and body weight loss. A 50-mm tumor found at the lesser curvature of the gastric antrum was histologically diagnosed as endocrine carcinoma. A computed tomography (CT) scan showed liver metastasis and multiple lymph node metastasis. We started chemotherapy with irinotecan and cisplatin every 4 week. After three courses of treatment, the primary lesion was estimated PR, the metastasis CR, and the synthesis PR. Then we performed distal gastrectomy with lymph node dissection. Histological findings revealed no cancer cells.

[Show abstract][Hide abstract] ABSTRACT: Histopathologically, early lesions of primary biliary cirrhosis (PBC) are focal within the liver and there is segmental involvement of the bile ducts. In addition, the development of PBC is variable within the liver. PBC is characterized by the following laparoscopic findings: reddish patch, mesh-like white marking and gentle undulation, etc.In the present study, we analyzed the correlation between the laparoscopic findings and the histological stage as per Scheuer's classification in 22 patients with PBC. The results of this study are summarized as follows:1) Reddish patch was frequently observed in the early stage of PBC. 2) Mesh-like white marking was observed in cases of stage I, II and III. 3) Gentle undulation was seen in stage II and III. The absence of this finding is useful in the diagnosis of stage I. 4) In stage IV, these three findings were not observed. 5) From these three findings, it was difficult to differentiate stage II or III. But the presence of portal hypertension and increased vascularity of the liver capsule were observed in accordance with the progression of the disease. Indications of portal hypertension were seen even in the early stage and in some asymptomatic cases of PBC.In conclusion, the laparoscopic findings such as reddish patch, mesh-like white marking, gentle undulaion and portal hypertension are very valuable for stage diagnosis and the evaluation of prognosis in patients with PBC.
[Show abstract][Hide abstract] ABSTRACT: Pancreaticopleural fistulas are a rare complication of acute or chronic pancreatitis, and are usually treated by surgery. We report three patients whose pancreaticopleural fistulas were successfully treated by endoscopic retrograde cholangiopancreatography and drainage (stenting, nasopancreatic drainage). In one patient a pancreatic pseudocyst persisted despite successful initial closure of the leak using this method and, as it was also suspected to be infected, additional drainage of the pseudocyst was required. Endotherapy of pancreaticopleural fistulas could obviate the need for surgery when conventional medical treatment has failed in this condition.
[Show abstract][Hide abstract] ABSTRACT: Thirty-four untreated hepatocellular carcinomas (HCCs) with known growth rates were classified into 5 groups on a tumor profile chart based on their doubling time (DT), Ki-67-positive index (Ki-67-PI), apoptotic index (Apo-I), and histologic grade. The slow-growing HCCs (DT > 100 days) consisted of well-differentiated tumors with slight cell kinetic imbalance and were divided into groups A and B. Group A had Apo-I values <3%, and most tumors had Ki-67-PI values <10%, whereas group B had Apo-I values of 3 per thousand to 10 per thousand and Ki-67-PI values of 10% to 20%. The HCCs with intermediate growth rates, which had Ki-67-PI values similar to those of the tumors in group B, were divided into groups C and D based on differences in cell kinetics: group C consisted of well-differentiated tumors, most of which had Apo-I values <3 per thousand, and group D consisted of moderately or poorly differentiated tumors with Apo-I values between 10 per thousand and 20 per thousand. The rapidly growing tumors (DT < 50 days, group E) had higher Ki-67-PI values than other groups and a wide range of Apo-I values. Rapidly growing tumors were mostly moderately or poorly differentiated, with a large cell kinetic imbalance in favor of cell production. This grouping system is useful for approximating the growth rate of HCCs in a clinical setting, even when only histologic parameters are available.
