Pyogenic liver abscesses secondary to carcinoma of the sigmoid colon: a case report and clinical features of 20 cases in Japan.

We report a case of liver abscesses associated with sigmoid colon cancer in an 81-year-old woman. The patient was referred to our hospital because of a tumorous lesion of the sigmoid colon. Five days before the scheduled operation, she presented abdominal pain, fever and chill.

Emergency operation for phlegmonous gastritis.

Phlegmonous gastritis is a rare inflammatory lesion in which bacterial infection occurs in the gastric wall. A case of phlegmonous gastritis producing an intramural filling defect in the stomach is presented. Endoscopy showed edematous and reddened gastric mucosa with a mass lesion in the gastric body and antrum.

Operated hepatocellular carcinoma in two HIV- and HCV-positive hemophilic patients.

Some hemophilic patients in Japan suffer from infections with both human immunodeficiency virus (HIV) and hepatitis virus because they received contaminated nonheated blood products. Coinfection with HIV appears to accelerate the course of chronic hepatitis. Although powerful antiviral therapy was introduced as HIV treatment and the prognosis of HIV patients was dramatically improved, the risk of rapid progression of hepatitis and carcinogenesis remains for the patients.

Treatment strategy of limited surgery in the treatment guidelines for gastric cancer in Japan.

Surgical practice for gastric cancer in Japan is based on the Gastric Cancer Treatment Guidelines issued in 2001 by the Japanese Gastric Cancer Association. These recommendations list options for treatment of each stage of cancer, with clear distinctions between interventions recommended for routine use and those that should be confined to trial settings until further evidence for their curative potential becomes available. In this review, we discuss standard surgery, local resection, segmental resection, and pylorus-preserving gastrectomy (PPG) as examples of limited resection and describe in detail the indications for limited lymph-node dissection in cases of early-stage gastric cancer.

Clinicopathological study for gastric cancer with liver metastasis.

Clinicopathological characteristics, stromal volume (Vvf), nuclear DNA content and cell protein were retrospectively analyzed in order to scrutinize the risk factors of hepatic metastasis from carcinoma of the stomach. We conducted a clinicopathological study of 327 patients with gastric cancer, including 34 patients with liver metastasis (synchronous, 22; metachronous, 12) and 294 patients without liver metastasis. Univariate analysis revealed significant inter-group differences in tumor size (p<0.

Is tumor size a prognostic indicator for gastric carcinoma?

Background: Retrospective studies using multivariate analysis of clinical and pathological features in gastric cancer have identified a number of high-risk, independent prognostic factors. In these clinical features, tumor size can be measured easily before or during the operation without the requirement of any special equipment, but its prognostic value in patients with gastric cancer is unclear. The aim of this study was to review the experience at our institution of gastric adenocarcinoma to determine the influence of tumor size on outcome.

Minute pancreatic carcinoma with initial symptom of acute pancreatitis.

We experienced a case of minute pancreatic carcinoma in a 59-year-old man who complained of upper abdominal pain after drinking alcohol. Abdominal ultrasonography (US) revealed dilatation of the main pancreatic duct (MPD). Abdominal computed tomography (CT) and magnetic resonance cholangiopancreatography (MRCP) showed slight dilatation of the MPD and its obstruction near the portal vein.

Early and late recurrences after gastrectomy for gastric cancer: a multiple logistic regression analysis.

Purpose: Although many studies have focused on clinical risk factors for prognosis of patients with surgically treated gastric cancer, little information is available regarding the timing of recurrent malignant disease. The purpose of this study was to determine the factors that are predictive of early and late recurrences after gastrectomy.

Patients And Methods: We reviewed the hospital records of patients with hisotological proof of gastric cancer who were admitted to Sendai National Hospital during the period from 1985 to 1995.
