ABSTRACT
Occasionally it is difficult to preoperatively confirm the bleeding focus in acute lower gastrointestinal bleeding patients. Therefore, many diagnostic evaluations are needed - for example, colonoscopy, selective mesenteric angiography and Tc-99m RBC scintigraphy. However, if the bleeding focus remains unconfirmed preoperatively when the patient's state is unstable hemodynamically, the surgeon must inevitably perform exploratory laparotomy, followed by intraoperative endoscopy. We herein propose a new method of intraoperative endoscopy using Trocar(R) (Ethicon). Trocar(R) (Ethicon) was used in laparoscopic operation. This method has the merits of no air leakage, no contamination, fewer complicatons and ease of evaluation. We recommend that the use of Trocar(R) (Ethicon) in intraoperative endoscopy is essential in emergency operations for acute lower gastrointestinal bleeding.

OBJECTIVES: To predict of the survival of patients with epithelial ovarian cancer, multivariable analysis was done to identify variables with independent prognostic factors. Based on materials from 191 clinical trials performed by Department of Obstetrics and Gynecology, Hanyang University Hospital, we constructed a prognostic index (Pp with considerable predictive power for long-term survival of patients with epithelial ovatian cancer treated with cis-platin based combination chemotherapy, METHODS: On identifying variables with independent prognostic value, statistical analysis were performed with clinicopathologic variables including age, FIGO stage, histologic subtype, histologic grade, residual tumor, presence of ascites, pretreatment levels of hemoglobin, platelet, and tumor markers(CA 125, CA 19-9). We also analyzed biological variables using immunohistochemical staining for GST-pie (glutathione-s-transferase-pie), p-glycoprotein, and MT (metallothinein) as a drug resistance and uPA (urokinase type plasminogen activator), PAI-1 (plasminogen activator inhibitor-l), nm23 (nonmetastatic gene 23) as a tumor invasion and metastasis. In addition, univariable analysis was performed followed by multivariable analysis using Coxs proportional hazards model to identify variables predictive of poor prognosis. Prognostic index (PI) was calculated based on sum of individual beta-coefficient of the most important independent prognostic value. RESULTS: With univariable analysis, age, FIGO stage, histologic grade, histologic subtype, presence of ascites, residual tumor, initial value of CA 125, MT, uPA, and PAI-1 were found to predict of patients survival. In the multivariable analysis and proportional hazard model, the pretreatment characteristics needed for the calculation of the PI are the age, the site of metastases expressed as stage, the histologic subtype, the size of residual tumor, the histological grade, and the presence of ascites. In the subgroup comprising the 10% of the patients with the best prognosis, 5-year survival rate was 78.9%, whereas in the subgmup comprising the 10% with the poorest prognosis, 5-year survival rate was 7.1%, which illustrates the large variability of the prognosis among patients. CONCLUSIONS: The PI was found to retain its value after response was achieved. The information provided by the PI can be expected to be useful in treatment planning and the proper stratification of patients in clinical trials.

A xanthoma is a localized collection of tissue histiocytes containing lipid and is usually associated with hyperlipidemia. Tendinous and tuberous xanthomatosis have been found in association with familial hypercholesterolemia, Type III hyperlipidemia, beta-sitosterolemia and cerebrotendinous xanthomatosis. Tendinous and tuberous xanthomatosis without hyperlipidemia have been reported very rarely. Especially tendinous xanthomatosis without hyperlipidemia have not been reported at all in korea. We are reporting a patient with tendinous and tuberous xanthomatosis accompanied by normal plasma lipids

Succinylcholine induces a small increase in serum K+ (0.3~0.5mEq/l) in normal patients, but it may produce fatal increases in sensitive conditions, including severe burn, massive trauma, tetanus and neuromuscular disorders. Recently, interest has been focussed on the role of the adrenergic system in extrarenal potassium hemeostasis. According to this concept, beta-adrenergic stimulation enhances and conversely a blockade imparis celluar uptake of potassium. Meanwhile propranolol, a beta-adrenergic blocker, is an incresingly, common drug among surgical patients. Therefore, the present experiment was carried out on 66 patients in order to determine whether propranolol augments or prolongs the increases in serum K+ following succinylcholine injection(2mg/kg, I.V.). Serum K+ and Na+ levels were measured just prior to induction and at 3,5,10,30,60,90 minutes following succinylcholine administration. The patients were divided into three groups: Group 1: 26 patients without propranolol treatment, Group 2: 20 patients pretreat with divided doses of propranolol (320 mg b.i.d. p.o.). and Group 3: 20 patients on chronic propranolol therapy. The results were as follows. 1) Baseline K+ valuses were significantly higher in propranolol treated patients(Groups 2 and 3) than in non-treated patients(Group 1). 2) The magnitude of maximum increases in serum K+ following succinylcholine was 0.19mEq/l, 0.16mEq/l and 0.21mEq/l in group 1,2 and 3, respectively. 3) The time to peak increases in K+ was 30min, 5min and 3 min following succinylcholine in group 1,2 and 3, respectively. 4) Serum Na+ decreased significantly following succinylcholine administration in all groups, but there was no significant difference among the groups at other times. These results indicate that propranolol neither augments nor prolongs increases in serum K+ following succinylcholin injection. Thus succinylcholine can be used safely in the presence of a beta-adrenergic blockade.
