Primary Hepatic Carcinoid Tumor: A case report / 한국간담췌외과학회지

A case of primary carcinoid tumor of the liver with striking central fibrous scar in a 61-year-old male is reported. Tumor cells contained electron dense secretory granules with an average diameter 150~200 nm which demonstrated positive immunohistochemical reaction for neuron-specific enolase, synaptophysin and chromogranin. The stellate central scar was observed in various hepatic tumors including focal nodular hyperplasia, fibrolamellar carcinoma, or sclerosing hepatocellular carcinoma, but have not been reported in carcinoid tumor.

Analysis of the Risk Factors in Colorectal Injuries

PURPOSE: To evaluate factors that influence morbidity and mortality in colorectal injuries. METHODS: We reviewed the medical records of 59 patients who underwent emergency operation in JNUH from Jan. 1988 through Dec. 1997. Univariate and multivariate analyses were used to calculate the prognostic significance of the following variables: sex, age, time to operation, preoperative shock, penetrating abdominal trauma index (PATI), APACHE II score, site of injury, organ injury scale (OIS), Flint grade, associated intraabdominal injuries, the sum of transfusion during 48hours of preoperative and postoperative period and operative method. RESULTS: Univariate analysis showed that colorectal organ iujury scale, and operative method were related to the complication, and preoperative shock, APACHE II score, PATI, and transfusion in 48hrs of injury were related to the mortality of colorectal injury. Multivariate logistic regression analysis showed that colorectal organ injury scale (2 vs 1) was significant risk factor in the development of complication, and the odds ratios were 5.0 and 1.69 respectively. The sum of transfusion in 48hours of injury was a only significant risk factor in the mortality and the odds ratio was 1.5. CONCLUSIONS: We concluded that preoperative condition was very important and preservation of hemodynamic stability was critical in improvement of prognosis. We also concluded that the shortening of operative time and proper management of associated injury may reduce the development of complication and even death.
