The common bile duct and the duct of Wirsung cojoin at the level of the duodenum, forming the major. papilla of Vater. Existence of a double major papilla, i.e., two neighboring independent papillary structure:, is infrequent. In our endoscopy unit we have experienced one case of double papilla of Vater wherein canulation of the common bile duct and pancreatic duct could be accom plished through either orifice independently.

The athors have presented recently treated 4 cases of malignant tumors of the eye and adnexa. 1. All of them were rapidly aggrevated after previous incompleted surgical management (3 cases) or postponement 01 operation (1 case). 2. Three cases of them except adenoid cystic Ca. were recurred after orbital exenteration. 3. The authors were concluded that the poor prognosis is due to its nature of malignancy and delayed radical surgical management.

Authors experienced a 59-year-old male patient with the lymphoma of the small iritestine which involved the adjoining mesenteric lymph nodes, the parietaI pleura, and the skin. The skin lesions, simulating necrotizing angiitis, were deep purple colored, asymptomatic, tense, hemorrhagic bullae with soft consistency on the both thighs and left infraorbital area. He had extranodal type, and diffuse, poorly differentiated lymphocytic lymphoma by the Rappaport classification, and stage IV by the Ann Arbor staging classification. After about 50 days of clinical manifestations, he was died mainly due to massive intestinal bleeding.

We tried to analyze the status of 10 units of frozen thawed apheresis platelet concentration by 6% DMSO method for the evaluation of practical applicability. The platelet concentrations were transferred to PL-732(Baxter, USA) cryopreservation bag, and DMSO is added to those bag at slow rate until expected final 6% concentration is achieved, thereafter those were directly placed to -80 degrees C refrigerator for freezing. Someday later from I week to 1 month, those were thawed at 37 degrees C water bath, and then washed by same volume of ABO matched plasma. In the course of cryopreservation, about 7% of platelets were lost and the mean recovery rate of platelet was 93% compared with those of unfrozen status. LDH, the values of platelet lysis, and pH were within normal limits, whereas platelet aggregation test shows decreased aggregation to collagen and ristocetine compared with those of unfrozen status(p<0.05) but they were clinically acceptable. We suggest that the frozen platelets may be useful in a some clinical situation such as hematologic malignancy and solid tumor by autologous transfusion.

The authors observed clinically typical case of unilateral coloboma of the optic disc. This patient, 5 years old Korean boy, visited to our clinic with the chief complaints of visual disturbance and intermittant exotropia of left defecting eye. The optic disc was enlarged about 2.5 times of normal optic disc diameter excavated about 7.0 Diopters in depth. The vision of colombomatous left eye was 20/50(n.c.) but the cause of defective vision was not evaluated certainely whether it might be due to coloboma itself or slight posterior subcapsular opacity of the lens.

Patients undergoing thoracotomy experience severe postoperative pain and marked respiratory impairment. Analgesics(narcotics or loeal anesthetics) administered via epidural catheter in epidural space have been shown to provide postoperative analgesia and improve respiratory mechanics after thoracotomy. Several different methods have been utilized in an attempt to reduce pain and pulmonary mechanics after thoracotomy. These include epidural blocks using local anesthetics, epidural narcotics, ketamine, steroid, and clonidine. These methods have been shown to provide pain relief with relative preservation of lung volumes in the postoperative period, but have disadvantages. Especially epidural local anesthetics may cause hypotension and motor blockade of lower extremities, and epidural narcotics may cause pruritus, nausea and vomiting, urinary retension and respiratory depression. In an attempt to provide excellent analgesia and improve pulmonary mechanics after thoracotomy and to decrease the side effects associated with the intermittent bolus administration of epidural narcotics or local anesthetics, we performed a study of continuously administered epidural infusion of small concentration of fentanyl combined with low concentration of bupivacaine. Twenty eight patients undergoing thoracotomy were randomized into groups based upon a postoperative pain regimen as indicated: Group I: intermittent intramuscualr injection of nalbuphine 0.2 mg/kg(n=13), Group II: continuous epidural injection of mixtures of 0.2/ bupivacaine and fentanyl 3 ug/ml(n= 15). Two, 8, 24 and 48 hours postoperative, the following indices were measured: visual analogue pain scale, vital capacity, tidal volume, arterial blood gas analysis(pH, PaCo2, PaO2), side effects, and 24 hour urine 17-ketosteroids. The results were as follows: 1) Pain score was evaluated by visual analogue pain scale postoperatively and the pain scores significantly decresed in group II as compaired with those in group L 2) Vital capacity and tidal volume in group II were more improved than group I. 3) There was no difference in arterial blood gas analysis except for decreased PaO2 at 2 hour and 24 hour compared with preoperative value in group L 4) Major complications in group II were two cases of nausea and vomiting, one case of urinary retension, whereas only I patient in group I complained of nausea and vomiting. 5) No significant difference occurred in 24 hour urine l7-ketosteroid at 24 hour and 48 hour postoperatively in group I and group II, which were within normal limits.

BACKGROUND: There has been a study reporting those cases with elevated blood pressure (BP) above 140/90 mmHg on admission and normotension on ward showed more increase in mean arterial pressure(MAP) and pressure-pulse product than the normotensive or hypertensive patients in both situations. But the mean ages of the groups were different each other. This study was done to see if the same results would come without age differences. METHODS: One hundred and sixty-two patients between the age of 45 and 64 were divided into three groups. The patients with BP below 140/90 mmHg on admission and on ward were included in group 1(N=66) and those with BP above 140/90 mmHg on admission and below 140/90 mmHg on ward, in group 2(N=42) and those with BP above 140/90 mmHg in both situations were included in group 3(N=54). Preiinduction BP, PR, the changes of BP, PR during operation, incidence of hypertension at post-anesthesia room(PAR), and the number of cases who needed the use of inotropics or antihypertensives perioperatively were checked. RESULTS: As for the increase of BP just before induction the group 2 showed the greatest, group 1 was the next, and group 3 showed the least compared to ward value. Just after induction group 1 showed the greatest, group 2 the next, and group 3 the least amount increase. As for the increase of preinduction pressure-pulse product(PPP) group 2 showed the greatest, group 3 the next, and group 1 the least compared to ward value. Just after induction group 1 showed the greatest, group 2 the next,and group 3 the least amount increase. CONCLUSIONS: Intensive anesthetic care is needed also at periinduction period for the patients who showed hypertensive BP on admission and normotension on ward thereafter.

Thoracic epidural anesthesia has been used to manage intraoperative and postoperative pain for thoracic surgical patients with general anesthesia recently, And this combined anesthesia has been associated with less sedation, earlier ambulation, blunting of the stress response and better pain control in the post-operative period. But the effects of thoracic epidural anesthesia on pulmonary shunt, pulmonary vasoactivity and oxygenation are still unknown. The author has investigated the effects of thorarcic epidural anesthesia on pulmonary hypertension induced by acute diffuse alveolar hypoxia and N(W) -nitro-L-arginine(L-NNA) in 12 mongrel dogs. Acute diffuse alveolar hypoxia which is similar to the early stage of acute respiratory failure may induce the pulmonary hypertension. And L-NNA, inhibitor of endothelium derived relaxing factor(EDRF), may also induce pulmonary hypertension under hypoxic state. The measurements were made three times, the first was baseline at room air ventilation. Following baseline recordings, saline 4 ml(group A, n=6) or 2% lidocaine 4 ml(group B, n=6) was injected through the epidural catheter and ventilation was started with hypoxic gas mixture(10% O2, 90% N2). The seeond measurements was made 30 min after the hypoxic ventilation and third was 20 min after infusion of L-NNA(50 mg/kg mixed with distill water 50 ml, infusion rate is 50 ml/20min) under the continuous ventilation with hypoxic gas mixture. The results were as follows: 1) There were significant changes in mean pulmonary arterial pressure, pulmonary vascular resistance in group A(p<0.05) and in arterial and mixed venous oxygen tension, arterial and mixed venous oxygen content, intrapulmonary shunt in both groups(p<0.05) 30 minutes after hypoxia but there were not significant differences between groups. 2) There were significant changes in mean pulmonary arterial pressure, in group B (p<0.05) and pulmonary vascular resistance, systemic vascular resistance and mixed venous oxygen tension and content in both groups (p<0.05) 20 miniutes after infusion of L-NNA under the continuous ventilation with hypoxic gas mixture but there were not significant differences between groups. But there were significant changes in central venous pressure in group B(p<0.05) and significant differences between groups(p<0.05) at 20 miniutes after infusion of L-NNA. These results indicate that thoracic epidura1 anesthesia does not influence the pulmonary hypertension directly and does not praduce any unfavorable hemodynamic events during pulmonary hypertension induced by acute diffuse alveolar hypoxia and N(W)-nitro-L-arginine. Therefore thoracic epidural anesthesia shoud be valuable assistant to the general anesthesia for pulmonary hypertensive patients.
