- OBJECTIVE: To evaluate the incidence and prognostic importance of micrometastatic disease in regional lymph nodes from Dukes' B colorectal carcinomas.DESIGN: Retrospective study.SETTING: University hospital, Sweden.SUBJECTS: 100 patients operated on for primary colorectal carcinoma, classified as Dukes' B lesions.INTERVENTIONS: The regional lymph nodes were re-examined immunohistochemically using monoclonal antibodies against cytokeratin.OUTCOME MEASURES: Incidence and prognostic importance of micrometastases.RESULTS: Micrometastases were found in 39% (39/100) of the patients. The number of positive cells in the lymph nodes examined varied from 1 to over 100. They appeared as single cells or small clusters of cells located within the capsule or in the peripheral sinus of the lymph node. At least three sections from each of three lymph nodes had to be examined to identify 95% of the patients with lymph node micrometastases. The outcome of the patients with micrometastases was not significantly different from that of patients with no epithelial cells in the lymph nodes.CONCLUSION: Micrometastases in regional lymph nodes are a interesting phenomenon but clinically seem to be of only weak prognostic value.

- Objective: To assess the impact of a standard moderately severe surgical operation on the mucosal amino acid content of the duodenum and the colon.Design: Open study.Setting: University hospital, Sweden.Subjects: Nine patients who were to undergo elective open cholecystectomy.Interventions: Endoscopically obtained biopsy specimens from the intestinal mucosa. Main outcome measures: Changes in the content of free amino acids in the duodenum and colon at three days postoperatively.Results: The concentration of glutamine in the duodenum increased by 27% and that of glutamic acid by 34% after operation, whereas their content in colon remained unaltered. The concentration of branched chain amino acids increased by 26% in the duodenal mucosa after operation and by 24% in the colonic mucosa. The total concentration of amino acids (excluding taurine) increased by 9% in the duodenum, but remained unaltered in the colon.Conclusion: This study shows characteristic and consistent alterations in the free amino acid content of the intestinal tract after a moderately severe operation.

- Objective: To find out if there is a correlation between AB0 type and the amount of blood lost at operation. Design: Retrospective study. Setting: One county and one university hospital, Sweden. Subjects: 540 patients who underwent primary prosthetic hip replacement under regional anaesthesia. Albumin (n = 298) or dextran (n = 242) were used as plasma substitutes. Main outcome measures: Estimated blood loss and number of units of red cell concentrates transfused. Results: The characteristics of the study groups were similar. In patients given albumin, the mean (SD) intraoperative loss with blood group 0 (n = 100) was 718 (413) ml and 2.7 (1.9) red cell units were given. Those with other blood groups (n = 198) lost 713 (469) ml and were given 2.5 (2.0) units. In patients given dextran with blood group 0 (n = 82), the intraoperative blood loss was 650 (337) ml, the postoperative loss 480 (222) ml and they received 2.1 (2.1) units. The corresponding values in the patients with other blood groups (n = 160) were 665 (351), 498 (208) and 2.5 (2.1) units. Conclusion: Blood group 0 was not associated with increased blood loss.
