This study was designed to provide a histopathological analysis focusing on fibrosis (staging) and necroinflammatory reaction (grading, hepatitis activity index: HAI) in noncancerous liver tissue, and mitotic index (MI) in cancerous liver tissue to predict prognosis in 81 patients with chronic hepatitis or cirrhosis who underwent hepatectomy for hepatocellular carcinoma (HCC). The incidence of grade 2/3 and higher HAI was higher in patients with viral hepatitis C. The incidence of grade 2/3 was associated with vascular invasion of HCC, postoperative liver dysfunction, and cancer recurrence. Higher MI (≥5) was significantly associated with vascular invasion, poor histological differentiation, and recurrence rate (P < 0.05). Multivariate analysis showed that higher grade was the factor strongly associated with cancer recurrence (odds ratio: 10.621, P = 0.006). Higher MI correlated with overall patient survival (P < 0.05) by univariate analysis. Grading and MI are the useful prognostic markers for predicting tumor recurrence and patient survival.

Background: The aim of this study is to determine whether gasless, video endoscopic transanal-rectal tumor excision (gasless VTEM) is a valid treatment for rectal carcinoid and laterally spreading tumors (LST). Methods: Eighty-four patients with an adenoma, adenocarcinoma (Tis/T1), or carcinoid tumor of the rectum were divided into three groups: (i) LST (n = 17 patients), (ii) carcinoid (n = 11), and (iii) control with other types of tumors (n = 56). Results: The LST group had a longer median operating time than in the control group, whereas the carcinoid group had a shorter operating time. Two patients (11.7%) in LST group developed peritoneal entry during the operation, while 2 patients (3.6%) in the control group experienced postoperative complications. During a median follow-up length of 55.2 months, one patient in the LST group developed a recurrence. Conclusions: Gasless VTEM is a simple, minimally invasive procedure used to treat LST and carcinoid tumors of the rectum. However, resection for the LST group had a high risk of peritoneal entry during operation.

To clarify the clinical usefulness of measuring branched chain amino acids and tyrosine ratio (BTR), which is correlated with Fischer's ratio, we examined the serum BTR level in 33 patients with liver diseases. Serum levels of branched-chain amino acids (BCAAs) and tyrosine were measured by the new enzymatic method, which costs inexpensive and is immediate compared to measuring Fischer's ratio. BTR was calculated as ratio of concentration of BCAA to tyrosine. BTR was correlated with levels of albumin, transaminase and cholinesterase and was lower in patients with chronic viral hepatitis, Child B cirrhosis and portal hypertension. In 19 patients who underwent hepatic resection included 8 for major hepatectomy, resected volume, blood loss, operation time and background of liver diseases were not associated with changes of BTR after hepatectomy. In patients with prolonged jaundice, postoperative BTR level was significantly lower between day 1 and 7 after hepatectomy. We concluded that serum BTR level was correlated with poor liver function and monitoring of BTR levels after hepatectomy may be useful to evaluate degree of hepatic damage after liver surgery.

This study was designed to provide an immunohistochemical analysis of tumor biological factors in 28 patients who underwent hepatectomy for cholangiocellular carcinoma (CCC). Analyzed factors were microvessel counts (stained by CD34) and proliferating cell nuclear antigen (PCNA). PCNA L.I. was correlated with serum level of CA19-9, which was correlated with a higher recurrence rate and shorter patient survivals. Microvessel counts were negatively correlated with tumor size. Furthermore, the microvessel count in CCC with mass-forming (MF) plus periductal infiltrating (PI) type associated with poorer survivals, was significantly lower compared to that of CCC with MF type or PI type. Neither microvessel counts nor PCNA L.I. were associated with any other clinicopathologic factors or cancer recurrence. The five-year overall and cancer-free survival rates were 26% and 13%, respectively. Patients with MF plus PI type, poorer differentiated carcinoma, stage 4A and higher CA19-9 level had shorter cancer-free and overall survivals after hepatectomy (p < 0.05). Cancer-free and overall survivals in patients with lower microvessel counts tended to be slightly worse but were not significantly different. Although tumor microvessel count and proliferating activity were correlated with prognostic clinicopathologic parameters, both factors might not be prognostic markers for predicting CCC recurrence and patient survival.

Management of a rectovaginal fistula (RVF) following low circular-stapled colorectal anastomosis is difficult and often unsatisfactory. We report herein the case of a 66-year-old woman who developed a RVF following low anterior resection using the double-stapling technique for rectal cancer. The RVF spontaneously closed with nonoperative treatment that included simple observation without dietary restrictions. The spontaneous closure occurred within approximately 25 days. Minimally symptomatic patients may be candidates for nonoperative treatment.

Background/Aims: We hypothesize that a subset of node-negative colorectal cancer patients exists that is at high risk for recurrence after curative surgery. Preoperative serum levels of sialyl Lewisa (CA19-9), sialyl Lewisx (SLX), sialyl Tn (STN), and carcinoembryonic (CEA) antigens were analyzed for their value in predicting for such a group. Methodology: One-hundred-forty-five patients with node-negative, T1-4, M0 colorectal cancers were divided into groups of low or high serum antigen levels. Disease-free interval served as the endpoint in evaluating the prognostic strength of each variable. Results: Twenty-seven patients (18.6%) were included in the high group for CA19-9 antigen, 11 (7.6%) for SLX, 13 (9.0%) for STN, and 51 (35.2%) for CEA. The median follow-up was 62.1 months. As compared to those with low levels, patients with elevated CA19-9 had a shorter disease-free interval (P=0.0026). No significant difference in disease-free interval was noted between low and high groups of SLX, STN, and CEA antigens. Cox regression analysis identified elevated serum CA19-9 level as a predictor for decreased disease-free interval, independent of T-stage or tumor location. Conclusions: Elevated preoperative serum levels of CA19-9 may serve as a useful marker in identifying patients with node-negative colorectal cancers at high risk for recurrence after surgery.

Background/Aims: The aim of this study was to clarify long-term outcomes of endoscopic mucosal resection (EMR) using a modified Buess technique for mucosal gastric cancer. Methods: The procedure included en bloc mucosal resection using a Buess-type rectoscope into the gastric lumen via a temporary gastrostomy under video camera guidance. We reviewed 5 patients who underwent this procedure between 1995 and 1997 with a single mucosal cancer of the stomach that was unsuitable for en bloc excision by endoscopic snare diathermy. Results: All tumors were superficial elevated types (type 0-IIa) located in the middle third and posterior wall of the stomach. Median maximum tumor diameter was 2.2 (range 1.1-3.5) cm. There was no operative mortality. One patient developed a hemorrhagic gastric ulcer postoperatively. All tumors histologically showed curative potential of the mucosal resection without margin involvement. During a median follow-up period of 64 (50-77) months, none of the patients developed local recurrence. One patient had an early gastric cancer that metachronously developed at another stomach site. Conclusion: Intragastric EMR using a modified Buess technique appears to be a useful treatment for cure of mucosal gastric cancer for a limited group of patients unsuitable for complete en bloc excision by endoscopic snare diathermy.

This study compares surgical outcomes for local resection of rectal tumors by two approaches: (1) gasless, video-endoscopic transanalrectal tumor excision (gasless VTEM); and (2) a conventional posterior approach. Gasless VTEM involves a modification of transanal endoscopic microsurgery (TEM) that incorporates a standard laparoscopic video camera without a CO 2 insufflation system. A series of 42 patients with 45 rectal tumors (9 adenomas, 36 adenocarcinomas) who underwent gasless VTEM between 1993 and 2000 were studied prospectively. The control group consisted of 26 similar patients who underwent conventional surgery (transsacral or transsphincteric approach) between 1985 and 1993. Age, gender ratio, tumor localization, maximum tumor diameter, and histology for the cases and the controls were similar, whereas operating time and blood loss were significantly greater in the control group (p < 0.001 and p < 0.001, respectively). The postoperative intervals until able to walk, urinary catheter removal, solid food intake, and discharge from hospital were significantly shorter in the gasless VTEM group (p < 0.001, p = 0.002, p < 0.001, and p < 0.001, respectively); analgesic requirements were significantly less (p < 0.001). There was no operative mortality in either group. Postoperative complications developed significantly less frequently in the gasless VTEM group than in the control group (7.1% vs. 38.5%; p = 0.003). During the median follow-up length of 73.3 months, no patient developed tumor recurrence in the gasless VTEM group, whereas one patient did in the control group. In conclusion, gasless VTEM is less invasive and allows shorter hospitalizations and reduced complications than the conventional posterior approach, thereby providing an attractive alternative for selected patients.

A 76-year old man with a history of chronic viral hepatitis and obstinate constipation was admitted to our hospital with severe abdominal distension. The patient had no remarkable abdominal pain or signs of any inflammatory disorders. An abdominal X-ray film showed massive intra-abdominal free-air, but no signs of ulceration or perforation were found in an upper GI series. However, a 3cm multi-cystic lesion was found in the lower intestines, protruding into the abdominal cavity next to the site of the massive free-air, ascites observed on CT images. Pneumatosis cystoides intestinalis (PCI) was thought to be the most probable diagnosis, and an emergency laparoscopy was performed to rule out the possibility of intestinal perforation and relieve the patient's symptoms. A laparoscopy examination revealed multiple cystic lesions in the terminal ileum, ascites, and a liver with the appearance of chronic hepatitis; no evidence of intestinal perforation was seen even in the area of the multiple cystic lesions. Other PCI in the colon was observed by postoperative colonoscopy. The patient recovered without any complications. Although conservative therapy has been described as a common initial treatment for patients with PCI, our experience suggests that performing a laparoscopy examination may be useful not only for confirming the diagnosis, but for reducing the massive pneumoperitoneum resulting from severe constipation in patients with PCI.

The author has experienced to practice the clinical works of cadaveric liver transplantation at a single transplantation center in Australia between 1999 and 2000. Hepatic arterial thrombosis causes higher rates of morbidity and mortality after liver transplantation. To know the associated factors, pathogenesis and patient outcome, data of 99 adult patients who underwent liver transplantation by the database for past two years were analysed. Ten patients (10%) had hepatic arterial thrombosis (HAT group). In donor demographics, brain death caused by cerebral stroke in the HAT group (90%) was significantly more than that in the non HAT group (49%) (p < 0.05). The mean amount of blood transfusion in the HAT group (26665ml) was significantly greater than that in the control group (15606ml) (p < 0.05). The mean hepatic arterial flow measured by Doppler flowmeter in the HAT group (214ml/min.) was lower than that in the control group (399ml/min) (p < 0.01). The rate of in-hospital death or retransplantation caused by severely biliary abscess with hepatic infarction or graft failure in the HAT group (40%) tended to be higher compared to the control group (13%) (p=0.053). In conclusion, decrease of bleeding and blood transfusion, and obtaining the adequate arterial blood flow during operation were important to prevent hepatic arterial thrombosis causing higher morbidity and mortality after liver transplantation.
