The usefulness of E-cadherin immunostaining as a marker of malignancy in the body fluids was investigated in the present study. Thirty-three histologically proven cases of cell blocks from the pleural, peritoneal, and pericardial fluids were studied by immunocytochemistry for E-cadherin antibody using LSAB method. These cases were cytologically diagnosed as adenocarcinoma (25 cases) and atypical cells (8 cases). Tumor cells showed strong positive membranous staining for E-cadherin antibody in 21 out of 25 cases (84%) of adenocarcinoma. E-cadherin staining was not found in 6 of 8 cases of suspicious maligancy. The sensitivity and specificity were 84% and 75%, respectively. Reactive mesothelial cells and inflammatory cells scattered were all negative. In conclusion, E-cadherin is an useful adjunctive marker to distinguish reactive mesothelial cells from the carcinoma cells in the body fluids.

Peterson's hernia is an internal hernia that can occur after Roux-en-Y anastomosis. It often accompanies small bowel volvulus and is prone to strangulation. Reconstruction of intestinal continuity after massive small bowel resection in a patient who undergoes near total gastrectomy and Roux-en-Y anastomosis can be difficult. A 74-year-old man who had undergone a near total gastrectomy and Roux-en-Y gastrojejunostomy for stomach cancer presented with abdominal pain. The preoperative computed tomography showed strangulated small bowel volvulus. During the emergent laparotomy, we found a strangulated Peterson's hernia with small bowel volvulus. After resection of the necrotized intestine, we made a new Roux-en-Y anastomosis connecting the remnant stomach and the jejunum with a transverse colon segment. We were safely able to connect the remnant stomach and the jejunum by making a new Roux-en-Y anastomosis utilizing a transverse colon segment as a new Roux-limb by two stage operation.

PURPOSE: Measurement of colon transit time is well-known physiologic study for patients with chronic constipation. But information we get from it is frequently inconsistent with patient's complaint. This study was designed to ascertain the actual significance of that measurement. METHODS: The subjects included two groups of patients with chronic constipation. One group consists of 32 patients(group A), The other group 36 patients(group B). Colon transit time study and defecographic examinations were done using previously described methods. But the former study was a little modified in group A, in which sodium phosphate enema was given at the previous day of oral intake of radio-opaque markers. Findings of colon transit time study and their relations to the defecographic results were compared with each other. RESULTS: As for the 5th day-findings of colon transit time, 6 cases(18.7%) were abnormal in group A and 3 cases(8.4%) in group B(statistically not different). As for the 3rd day-findings, 15 cases(46.9%) were abnormal in group A and 7 cases(19.5%) in group B( statistically different, p=0.0163). Defecographic findings showed 7 cases(21.9%) of outlet obstruction pattern in group A and 9 cases(25%) in group B. Correlations between these findings and those of colonic transit time studies were not proven statistically. CONCLUSION: Colon transit time study with single marker bolus and the 5th day photography technique was considered not to reflect the actual conditions of patients with chronic constipation. But sodium phophate enema, given to patients before starting the study, seemed to enhance the accuracy of study.
