To identify significant prognostic factors in patients undergoing simple hysterectomy in the presence of invasive cervical cancer, the records of 45 patients who had taken such a procedure between 1993 and 1997 were reviewed. Overall relapse-free survival and 5-year survival rates were 91.1 and 92.1%, respectively. Factors found to be significantly related to survival were the retrospectively determined stage(p=0.0000), the presence of residual disease(p=0.0001), and cell type(p=0.0000). By multivariate analysis, factor emerging as significantly detrimental to survival was the cell type. The presence of residual disease was a marginally significant factor(p=0.067). The expectations for survival of patients with residual tumor mass and/or with adenocarcinoma after simple hysterectomy appear to be markedly worse than those with others, so radical reoperation should be considered in those patients.

Gastritis cystica profunda (GCP) is an uncommom hyperplastic lesion, which is located within the submucosa. GCP may occur several years after previous gastric surgery. In some reported cases, it was a premalignant condition and may lead to carcinoma of the stomach. We report a case of a 54-year-old man with epigastric pain and dyspepsia. He had undergone peritoneal dialysis for end stage renal disease about 13 years prior. An Upper gastrointestinal endoscopy showed elevated lesion at the gastric antrum, looking like an advanced gastric cancer or gastrointestinal stromal tumor. Endoscopic biopsy results were tubular adenoma with low-grade dysplasia. When followed up 9 months later, the lesion had increased in size and symptoms remained. We therefore performed a subtotal gastrectomy. The final biopsy was adenocarcinoma arising in GCP.

Ultrasonography is a predominantly accurate, relatively simple unique diagnsotic method of obstructive jaundice. The ultrasonographic findings of obstructive jaundice are dilated intra- and extrahepatic duct with intraluminal hyperreflective echo or mass in and/or around the bile duct. The superiority of high resolution real time ultrasonography for the diagnosis of obstructive jaundice is based on the easy detectability of extra-and intrahepatic bile ducts by its multiple sectional images in a short time, the flexibility of probe and the small crystal size. Author evaluated real time sonographic findings 46 obstructive jaundice patients confirmed by surgery or radiographical examinations. The results were: 1. Diameter of extrahepatic duct in obstructive jaundice were varied from normal to 4.0 cm, mostly 8 to 10 mm in diameter (26%). Degree of dilatation of biliary duct appeared more prominent in cancer patients than any other causes of obstruction. 2. The site of obstruction was detected in85% (39/46) and its common site was common bile duct in 63% (29/46). 3. The diagnostic accuracy of choledocholithiasis and cancer was 82% (22/27) and 44% (4/9), respectively. Diagnostic accuracy of the real time ultrasonography in obstructive jaundice was over all 75% (34/46).

PURPOSE: The role of peritoneal washing cytology in determining further treatment strategies after surgery for gastric cancer remains unclear. One reason for this is the fact that optimal procedures to increase the accuracy of predicting peritoneal metastasis have not been established. The aim of this study was to evaluate the efficacy of cytology using samples harvested from two different abdominal cavity sites during gastric cancer surgery. MATERIALS AND METHODS: We prospectively recruited 108 patients who were clinically diagnosed with locally advanced gastric cancer (higher than cT1 stage disease). Peritoneal washing fluids were collected from the pouch of Douglas and the subphrenic area. Patients were prospectively followed up for 2 years to determine the recurrence and survival rates. RESULTS: Thirty-three patients dropped out of the study for various reasons, so 75 patients were included in the final analysis. Seven patients (9.3%) showed positive cytology findings, of whom, three showed peritoneal recurrence. Tumor size was the only factor associated with positive cytology findings (P=0.037). The accuracy and specificity of cytology for predicting peritoneal recurrence were 90.1% and 94.2%, respectively, whereas the sensitivity was 50.0%. The survival rate did not differ between patients with positive cytology findings and those with negative cytology findings (P=0.081). CONCLUSIONS: Peritoneal washing cytology using samples harvested from two different sites in the abdominal cavity was not able to predict peritoneal recurrence or survival in gastric cancer patients. Further studies will be required to determine whether peritoneal washing cytology during gastric cancer surgery is a meaningful procedure.

From May 1991 to December 1993, 30 male bladder cancer patients with 34 to 68 years old age (mean age 52.4 years) underwent bladder replacement with the ileocolic neobladder. A divided segment of ileum and colon was used to create a neobladder after radical cystectomy with a cecourethral anastomosis to provide volitional voiding with continence. Urodynamic studies were followed up 3, 6, l2 and 18 months postoperatively. The mean maximal reservoir capacity was 420+/-87.7, 553+/-65.3, 565+/-60.3, 563+/-53.5ml, mean maximal reservoir pressure was 33.2+/-7.5, 24.2+/-6.1, 24.0+/-5.9, 23.1+/-6.3cmH2O, mean maximal urethral closure pressure was 57.9+/-9.5, 61.3+/-7.6, 61.0+/-7.3, 61.5+/-6.9cmH2O, maximal flow rate was 23.2+/-7.2, 24.3+/-5.8, 24.0+/-6.1, 24.1+/-5.4ml/s and residual urine was 40.0+/-10.3, 35.0+/-7.8, 24.0+/-6.1, 24.1+/-5.4ml/s. The daytime continence rate was 100% and the nighttime continence rate was 93% at 6 months postoperatively. With its very good functional results and its ease of performance, ileocolic neobladder may be one of the ideal urinary diversion for bladder substitution after radical cystectomy.

Gastric emptying in patients after several upper gastrointestinal surgeries was studied using the acetaminophen method. The subjects consisted of 23 gastric cancer patients, 2 duodenal ulcer patients, 5 periampullary cancer patients and 4 normal subjects. As an indicator of the gastric emptying rate, the serum acetaminophen concentration was measured by fluorescence polarization immunoassay, in units of g/ml, at 0, 30, 60, 120, and 180 minutes after ingestion of a liquid meal with 1.5 g of acetaminophen. In the normal subjects, the acetaminophen concentrations were 0, 16.35+/-5.06, 18.71+/-5.58, 16.38+/-4.82, and 11.09+/-3.62 g/ml at time 0, 30, 60, 120, and 180 min, respectively. The concentration peaked at 60 min after ingestion of the test meal in the normal subjects. We observed significant delayed gastric emptying after pancreas preserving pancreaticoduodenectomy (PPPD) and a standard Whipple's operation in the early postoperative period. In all patients with a subtotal gastrectomy, a truncal vagotomy was done. However, in patients with a pancreaticoduodenectomy, the vagus nerves were preserved. The gastric emptying pattern was different between the patients with a subtotal gastrectomy and the patients with a pancreaticoduodenectomy, despite similar reconstructions of the gastroenterostomy (Billroth I or Billroth II type reconstruction). There was more rapid gastric emptying in patients with a truncal vagotomy and pyloroplasty than in the normal subjects. Hence, we speculate that the truncal vagotomy was the main cause of the different gastric emptying between the patients with a pancreaticoduodenectomy and the patients with a subtotal gastrectomy.
