Abstract
OBJECTIVES High-fidelity simulation (HFS) calls heavily upon cognitive capacities and generates stress and anxiety. The objectives of this prospective, observational study were to assess trait anxiety and fear of negative evaluation (FNE) in anaesthesiology and critical care residents and appraise their state anxiety levels and cardiovascular responses during HFS training sessions. SUBJECTS AND METHODS First-year anaesthesiology and critical care residents completed the French-Canadian adaptation of the State-Trait Anxiety Inventory (IASTA Y-1: state anxiety, IASTA Y-2: trait anxiety) and the French adaptation of the Fear of Negative Evaluation Scale (FNE). Their heart rate (HR) and blood pressure (BP) were assessed before and after the training session. RESULTS Twenty-three residents (8 women, 15 men) were included in the study. IASTA Y-1 and Y-2 scores were low (respectively 40.2±9.9 and 39.7±8) and FNE scores were moderate (16.7±5.5). HR measurements before and after the training sessions were significantly higher than at rest (respectively 78±19, 80±17 and 63±9b/min; P<0.001). BP measurements before and after the HFS sessions were not significantly different. The IASTA Y-2 and FNE scores of female residents were significantly higher than those of male residents (respectively P=0.004 and P=0.049). CONCLUSION First-year anaesthesiology and critical care residents had low trait anxiety and FNE. HFS training increased their HR but not their BP. Their state anxiety also remained low. Several differences between individuals were noted, particularly between men and women.

Abstract
There is no standard treatment for patients with pleural malignancies. The aim of this prospective study was to investigate the toxicity and long-term results of a multimodality treatment consisting of surgery and intrathoracic chemohyperthermia (ITCH) for the treatment of patients with pleural malignancies. From January 1990 to August 2000, 24 patients with mesothelioma (n=17), fibrosarcoma (n=3), pleural adenocarcinoma (n=3) and thymoma (n=1) were included. The mesothelioma stages were T1 or T2 in 10 cases, and T3 or T4 in seven cases. After cytoreductive surgery, ITCH was carried out for over 60 min, at inflow temperatures less than 45 degrees C, either with mitomycin C (n=7) or cisplatin (n=5) or both (n=12). One patient died from major thoracic air leaks after major decortication and pleurectomy. Seven patients had complications, one pleural clotting necessitating reoperation. After a median follow-up of 89 months, the overall 1-year and 5-year survival rates were 74 and 27%, respectively. For T1 and T2 mesothelioma patients, the median survival was 41.3 months, and for T3 and T4 tumours, it was 4.5 months (P=0.001). The fibrosarcoma patients are alive with no evidence of recurrence at 24, 43 and 54 months. In the conclusion, the combination of surgery with ITCH with mitomycin and/or cisplatin is relatively safe. This procedure may offer unexpected long-term survival in a selected group of patients (T1 and T2 mesothelioma patients and fibrosarcoma patients).

Abstract
This paper proposes a program for continuous estimation of respiratory mechanics parameters in ventilated patients. This program can be used with any ventilator providing airway pressure and flow signals without additional equipment. Overall breathing resistance, dynamic elastance (E) and positive end expiratory pressure (P(0)) are periodically estimated by multiple linear regression on selected parts of breathing cycles. Experimental validation together with justification of the selection procedure are based on signals obtained while ventilating a lung mechanical analogue with various intensive care ventilators. Clinical validity has been tested on 12 ventilated patients. The quality of estimation has been assessed by mean square difference between measured and reconstituted pressure (MSE), coefficient of determination (R(2)) and the condition number (a confidence index), and by comparison of E and P(0) with corresponding static values. The high R(2) and the low MSE obtained on most clinical cycles indicate that selected parts of cycles obey closely the model underlying parameter estimation. Agreement between static and dynamic parameters demonstrates the clinical validity of our program.

Abstract
The instantaneous pressure applied by the respiratory muscles [Pmus(t)] of a patient under ventilatory support may be continuously assessed with the help of a model of the passive respiratory system updated cycle by cycle. Inspiratory activity (IA) is considered present when Pmus goes below a given threshold. In six patients, we compared IA with (i) inspiratory activity (IAref) obtained from esophageal pressure and diaphragmatic EMG and (ii) that (IAvent) detected by the ventilator. In any case, a ventilator support onset coincides with an IA onset but the opposite is not true. IA onset is always later than IAref beginning ((0.21 +/- 0.10 s) and IA end always precedes IAref end (0.46 +/- 0.16 s). These results clearly deteriorate when the model is not updated.

Abstract
PURPOSE To describe per and postoperative medical complications. STUDY DESIGN Prospective, observational study. PATIENTS Between July and December 1999, 59 patients scheduled for programmed orthognathic surgery were included. METHODS Anaesthetic and surgical procedures were standardised including patient information and training of surgical ward' nurses. During perioperative periods (in operative and recovery theater and in surgical ward), all the events were qualified on an anaesthetic spreadsheet for a qualitative analysis (description of events and treatment procedures). RESULTS Two main complications were described 1) one atelectasia due to blood inhalation during the recovery period and 2) local sepsis in surgical ward. These two events were medically treated and recovered. No need of blood transfusion or stay in ICU were noted. CONCLUSION Anaesthetic and surgical cooperation is associated with poor morbidity of this functional surgery performed in young subjects.

Abstract
OBJECTIVE To evaluate the efficiency of haemodynamic and respiratory monitoring system by a clinical analysis of the alarms. STUDY DESIGN Observational prospective study. PATIENTS 25 patients who presented acute respiratory distress syndrome and who were monitored with haemodynamic and respiratory monitoring. METHODS Each minute, a bedside clinical observer analysed alarms from the monitoring according to detection or absence to clinical events. Four situations were defined to statistical descriptive analysis: a) false positive (FP); b) true positive (TP); c) false negative (FN); and d) true negative (TN). True positive alarm which induced consequences on patients care were also analysed. RESULTS 15,013 minutes allowed the recordings of 3,665 alarms, 44% from arterial pressure, 17% from SpO2 and 12% from airways maximal pressure. 46% were false positive alarms inducing a noisy pollution. The positive predictive value PPV = TP/(TP + FP) of these alarms were respectively 51% for arterial pressure, 18% for SpO2 and 100% for Paw. Only 5% of true positive alarms induced consequences on patients care. CONCLUSION This protocol allowed the evaluation of monitoring efficiency. This kind of evaluation may help to improve monitoring capacity with reducing noisy pollution from false positive alarms.

Abstract
UNLABELLED The abdominal wall lift (AWL) has been proposed for laparoscopic cholecystectomy to reduce hemodynamic effects caused by carbon dioxide (CO2) and high intraabdominal pressures (IAP). Data concerning effects of AWL on respiratory mechanics are scant. We therefore used a noninvasive method to evaluate whether the AWL could offset these effects. The PETCO2, airflow, and airway pressure were continuously measured in nine patients undergoing laparoscopic cholecystectomy using an AWL with minimal CO2 insufflation. We used a least-squares method to calculate maximal airway pressure (Pmax), elastance (Ers), and resistances (Rrs) of the respiratory system. After CO2 insufflation, the initiation of AWL resulted in a significantly decreased IAP (from 13 to 6 mm Hg; P < 0.001) and Rrs (from 20.6 to 17.8 cm H2O.L(-1).s(-1); P = 0.029), whereas Ers was partly modified (34.0 to 33.3 cm H2O/L; not significantly different). With AWL, we hypothesized that the diaphragm remained flat and stiff, outweighing the beneficial effect of the decrease of IAP on Ers. PETCO2 significantly increased after AWL and at the end of the procedure. We conclude that AWL partly reverses the impairment of the respiratory mechanics induced by CO2 insufflation during laparoscopic surgery. IMPLICATIONS The abdominal wall lift (AWL), acting on the abdominal chest wall, had some benefits during laparoscopic surgery by limiting CO2 peritoneal insufflation and several side effects, such as hemodynamics. We examined the consequences of this technique on respiratory mechanics in nine patients undergoing laparoscopic cholecystectomy. Our findings suggest that the AWL decreases intraabdominal pressure and respiratory resistances without a significant effect on respiratory elastance.

Abstract
OBJECTIVE To assess the accuracy of respiratory inductive plethysmography (RIP) waveforms to those obtained with whole body plethysmograph (BP) as this device gives a plethysmographic signal and a pneumotachograph (PNT). DESIGN Randomized controlled trial. SETTING Physiologic laboratory in a university hospital. PARTICIPANTS Eleven subjects from the laboratory staff. INTERVENTIONS This study was achieved during four consecutive periods in subjects breathing spontaneously and through different added resistive loads. Using the least square method calibration, two RIP waveforms, VRIP.BP(t) and VRIP.PNT(t), were simultaneously calculated with coefficients obtained from BP and from PNT volume waveforms, respectively VBP(t) and VPNT(t). For each recording, to compare volume waveforms, we calculated their differences in term of distances, DRIP-BP and DRIP-PNT, between the normalized RIP volume signal (respectively, VRIP.BP[t] and VRIP.PNT[t]) and its normalized reference (respectively, VBP[t] and VPNT[t]). We also calculated the distance DPNT-BP between the two normalized references VBP(t) and VPNT(t). RESULTS No significant effect of load or time on the distance occurred. Including all the recordings, the mean distance DRIP-BP (3.4+/-1.1%) appears significantly lower than both the mean distance DRIP-PNT (4.5+/-1.3%; p<0.04) and the mean distance DPNT-BP (4.6+/-0.9%; p<0.008). For each period or load level, DRIP-BP appears to be lower than DRIP-PNT and DPNT-BP. CONCLUSION The RIP seems reasonably accurate for analysis of respiratory waveform while subjects subsequently breathe against resistive loads.

Abstract
PURPOSE To estimate the leak between the endotracheal tube and the trachea in newborns in order to compensate for errors in airflow measurement and to monitor mechanical variables from pressure and flow signals. METHODS Assuming that the leak resistance (Rf) is constant during a respiratory cycle, the resistive properties of the endotracheal tube were evaluated. The method was validated in the intensive care unit with a mechanical test lung and assessed on recordings of three newborns during mechanical ventilation for RDS. We have used a least squares method for the estimation of positive end expiratory pressure (PEEP) on both newborns and simulated data. RESULTS Direct measurements of simulated leak resistances on the mechanical lung are in agreement with our estimation of leak resistances. In newborns, the success of flow correction is evidenced on end inspiratory pauses: corrected flow drops to zero while raw data show a constant nonzero flow. On the simulated lung, the PEEP underestimation with uncorrected flow ranges from 10 to 20 cm H20 while the corresponding, underestimation with corrected flow is less than 2 cm H2O. In newborns, the flow correction shifts the estimated PEEP from negative values (-0.3 +/- 1.3 cm H2O before correction) to positive values (3.6 +/- 0.7 cm H2O after correction) higher than the imposed PEEP (2 cm H2O). CONCLUSIONS The efficiency of this simple method has been demonstrated. It could be used successfully on adult patients, as there will not be flow correction in the absence of leaks.

Abstract
OBJECTIVE To assess the efficiency of corticosteroids and preoperative acute normovolaemic haemodilution (PANHD) in reducing postoperative inflammation after maxillofacial surgery. STUDY DESIGN Randomized clinical trial. PATIENTS Thirty-two patients scheduled to undergo maxillary osteotomy for facial dysmorphia were randomized into four groups of eight (PANHD or not; corticosteroids or not). METHODS PANHD decreased haematocrit to 30%. In the corticosteroid groups, methylprednisolone 1.5 mg.kg-1 was given intravenously at the beginning of surgery (after PANHD in haemodiluted group), and after surgery, 1.5 mg.kg-1 iv daily for three days. Postoperative inflammation was assessed with an X-Ray technique (radiotelemetry) providing data on tissue thickness (extent of facial oedema), and by measurement of plasma concentrations of four acute phase proteins during the first postoperative week. RESULTS No change in facial oedema and in acute phase proteins occurred with PANHD. Corticosteroids decreased postoperative oedema and acute phase proteins. CONCLUSION Corticosteroids decrease postoperative inflammation after maxillofacial surgery but not PANHD.

Abstract
A program for automatic and periodic determination of respiratory mechanics in artificially ventilated patients is described. Airway pressure and flow signals are obtained from the ventilator in the controlled ventilation mode with constant flow inflation and end-inspiratory pause. Periodically, the program records both signals for a given time and it delimits a ventilatory cycle and its components out of this record. Then, four mechanical parameters of the respiratory system are calculated: (1) Rinit, the resistance obtained with the end-inflation occlusion technique; (2) Ers, the elastance (inspiratory) calculated from the slope of the airway pressure profile during inflation; (3) tau, the expiratory time constant; (4) PEEP, the global positive end expiratory pressure. All parameter measurements have been evaluated in experimental conditions, and are in good agreement with reference values. The complete software includes the display of the signals and of the trends together with automatic disk file backups. An additional program allows one to display the trends again and to create table text files containing all the recorded data for further analysis. The system proved to work in ICU and anaesthesia patients with various ventilators.

Abstract
The place of preoperative acute normovolaemic haemodilution (haematocrit = 28%-32%) in reducing postoperative inflammation was evaluated after facial surgery. Thirty-two patients scheduled for mandibular osteotomy were randomized to a nonhaemodiluted group or to a haemodiluted group. The degree of postoperative inflammation was evaluated: first by an x-ray technique (radiotelemetry) providing measurements of the tissue thickness (quantitation of facial oedema), and second by the measurement of four acute phase protein plasma concentrations during the first postoperative week. Throughout the study, no changes in facial oedema or in variation of acute phase proteins were detected after haemodilution. It is concluded that acute normovolaemic haemodilution has no effect on the intensity of facial oedema and the biological inflammation process after facial surgery.

Abstract
Intraperitoneal chemo-hyperthermia with mitomycin C was used to treat 28 patients with far advanced digestive adenocarcinoma and histologically confirmed peritoneal carcinomatosis. Surgical resection of the primary tumor was possible in 17 cases. After closure of the abdominal wall, intraperitoneal chemo-hyperthermia was performed for 90 to 120 minutes under general anesthesia and 32 degrees C hypothermia, through 3 intraperitoneal drains forming a closed circuit, using 10 mg/l of mitomycin C in 6 liters of peritoneal dialysate heated to an inflow temperature of 46-49 degrees C. No mortality occurred, and there were 2 post-operative complications, with transitory biological side effects. In 9 out of 10 patients with preoperative malignant ascites, the ascites cleared after treatment. One-year survival rate was 54.2%. These encouraging preliminary results show that intraperitoneal chemohyperthermia with mitomycin C is a safe and reliable treatment for peritoneal carcinomatosis in far advanced digestive cancers.

Abstract
The abdominal pressure is a hydrostatic one, which can be measured in the bladder, the rectum and the stomach. In physiologic conditions, the abdominal pressure is variable, with peaks as high as 100 to 200 mmHg at the time of defecation, cough. The increase in abdominal pressure elicited by abdominal distension or compression acts directly on the abdominal compartment, indirectly on the thoracic compartment, and modifies the circulation and the ventilation. Venous return is decreased as the inferior vena cava is compressed. The systemic resistances are also increased as the abdominal vessels are compressed. Therefore the circulation is mainly distributed to the superior part of the body. Although the cardiac output is decreased, the usual haemodynamic parameters remain in the normal range: arterial pressure is increased, heart rate is unchanged, central venous pressure is increased, cardiac failure is unusual. The abdominal distension is also responsible for a restrictive respiratory syndrome, mainly due to the ascension of the diaphragm. The compression of the abdominal content explains renal effects and the decreased diuresis. A sustained increase in abdominal pressure occurs in several clinical conditions. During coelioscopy, abdominal pressure is a under control and the cardiovascular effects are minor. Insufflation with CO2 carries the risk of hypercapnia, gas embolism and pneumothorax. During abdominal tamponade, anuria is directly related to the level of pressures. At an abdominal pressure over 25 mmHg, anuria is common and decompression becomes essential. The G suit increases arterial pressure either by elevating vascular resistances or increasing blood content in the upper part of the body. Therefore cardiac tolerance can be decreased especially in cardiac patients. The adverse effects of abdominal pressure can also be observed in case of peritoneal dialysis and ascites. The risk of regurgitation associated with an increased abdominal pressure must also be kept in mind. The abdominal pressure plays an important role in anaesthesia as well as in surgery. Therefore its measurement, which is easy, should become a routine.

Abstract
The aim of this work is to estimate the 24-hour distribution and elimination of mitomycin C (MMC) during and after intraperitoneal chemohyperthermia (IPCH) in 18 patients (13 gastric adenocarcinoma, 3 pancreatic adenocarcinoma, 2 malignant mesothelioma) who received 60 mg MMC during 90-120 min in 6 liters of heating solution HS; (42 degrees C) or HS flowing at 0.4 liters/min in a closed circuit. MMC assay in the serum, urine, HS and in local biopsies were performed by high performance liquid chromatography. The amount of MMC in HS decreased by 54.1 +/- 13.6% during IPCH. The maximum MMC levels in serum reached 0.4 +/- 0.18 mg/l 45 min after the start of IPCH, then rapidly decreased. Only 1.77 +/- 0.93 mg were recovered in urine in 24 h. These data are consistent with a large and rapid absorption, mostly in local tissue, demonstrated by the level in 7 post-IPCH biopsies (8.3 +/- 7.6 mg/kg).

Abstract
The prognosis of malignant pleural tumors remains extremely unfavorable. The aim of this study is to evaluate the combination of intrathoracic intrapleural chemotherapy and intrapleural hyperthermia (ITCH) in these diseases. Under anesthesia, 5 men were studied. After pleurectomy for mesothelioma (3/5) or adenocarcinoma (2/5), ITCH is carried out for over 60 min, either with mitomycin C (4/5) or cisplatin (1/5). No pre- or postoperative death occurred. The maximal pleural temperature is 42.6 degrees C. The blood level of mitomycin C never reached the systemic toxic level. All the patients were discharged from the surgical ward, 3 are still alive 15 months later. Therefore, ITCH appears to be a safe and reliable therapy.

Abstract
Intraoperative chemohyperthermia is a new method in the treatment of peritoneal seedings from digestive cancers, which combines surgery, intraperitoneal chemotherapy (mitomycin C and/or cisplatyl) and peritoneal hyperthermia. After a brief reminder on the general principles concerning high temperature action, a review of literature is made: 5 teams have performed this technique. We differentiate the indications, design features and results of each team. The results show a mean survival after 2 years of 35% (in peritoneal carcinomatosis) up to 78% (in gastric serosal invasion, peritoneal seeding free). The best result of the method is the drying up of cancerous ascites, allowing a more comfortable survival.

Abstract
The biochemical changes in blood during intraperitoneal chemohyperthermia (IPCH) were examined by carrying out complete assessments before and after the operation. These assessments were made up of 23 parameters: Na, K, Cl, CO2, urea, creatinine, proteins, glucose, calcium, phosphates, magnesium, bilirubin, uric acid, lactic acid, CRP, ASAT, ALAT, CK, LDH, gamma-GT, ALP, lipase, and amylase. Only 5 of these parameters showed significant changes: proteins, urea, ALP, gamma-GT, lactic acid. The protein and urea levels decreased due to hemodilution induced by the perfusion of fluids. ALP and gamma-GT levels decreased, possibly due to localized inhibition of secretion. Lactic acid levels increased due to the movement of lactates from the heated fluid into the blood. The study of biochemical changes within the heated fluids was made using the following parameters: CA 125, CA 19-9, CEA, ASAT, ALAT, CK, LDH, gamma-GT, ALP, lipase, uric acid, phosphates, proteins, Na, K, Cl, urea, creatinine, and magnesium. Between the beginning and the end of IPCH, significant increases were found in the levels of CA 125 (+173%), proteins (+190%), ASAT (+130%), LDH (+103%), K+ (+232%), PO4 (+134%), and uric acid (+99%). These increases indicate the existence of a significant degree of cellular lysis.

Abstract
The aim of the present work is to investigate in vivo cytokine production during chemohyperthermia. 11 patients suffering from gastric adenocarcinoma (n = 6), ovarian adenocarcinoma (n = 4) or malignant mesothelioma (n = 1) were studied. Patients received 60 mg mitomycin or 100 mg cisplatin per square meter during 2 h in 6 liters of a heating solution (temperature 42 degrees C, flow rate 200 ml/min in a closed circuit) after previous surgical resection. Tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) were measured at 0, 30, 45, 60 and 90 min, both in the blood stream and in the heating solution circulating intraperitoneally. We observed a slight increase in plasma IL-6 occurring as soon as 30 min, a dramatic rise in IL-6 in the heating solution. TNF-alpha values were only slightly augmented. In addition, the importance of various factors in the induction of IL-6 and TNF-alpha production during chemohyperthermia (temperature, mitomycin C, cisplatin) were studied using a whole blood ex vivo model.

Abstract
Intra Peritoneal Chemo Hyperthermia (IPCH) with Mitomycin C (MMC) or Cisplatinum (CP) was used to treat 32 patients with far advanced digestive or ovarian cancers and peritoneal carcinomatosis. Surgical resection of the primary tumor has been possible in 18 cases. After closure of the abdominal wall, a 90 minutes IPCH as performed under general anaesthesia and 32 degrees C general hypothermia, through 3 intraperitoneal drainages realizing a closed circuit, using 10 mg/l of MMC or 15 to 25 mg/l of CP in 6 l of peritoneal dialysate heated at the inflow temperature of 46 to 49 degrees C. The mortality rate was 3% and the morbidity rate was 3%. In 11 out of 12 patients with preoperative malignant ascites, no more ascites could be found after IPCH. For peritoneal carcinomatosis from digestive origin, median survival was 11.2 months and 1 year survival rate was 46.9%. These encouraging preliminary results show that IPCH is a safe and reliable treatment for peritoneal carcinomatosis in far advanced digestive or ovarian cancers.

Abstract
Tolerance of intraperitoneal chemohyperthermia (IPCH) with mitomycin C (2 mg/kg) by irrigation of the peritoneal cavity via a closed circuit system was evaluated in Beagle dogs for possible use in the management of human peritoneal carcinomatosis. Of dogs, 24 underwent three digestive anastomoses each. They were randomized into three groups: control (n = 6), intraperitoneal hyperthermia (n = 8) and IPCH (n = 10). Peritoneal temperatures were maintained between 41-43 degrees C for 60 min. Tolerance was evaluated through clinical follow-up, biological samples (serum electrolytes, blood counts and serum enzymes), histological examinations and post-mortem macro- and microscopic controls of anastomosis. Mortality and morbidity rates were not different in the three groups. No anastomotic leakage occurred. Evidence of biological toxicity was minimal. Histological examinations showed no definitive tissue damage. IPCH appears to be a safe and reliable device in dogs. Plans to combine IPCH with MMC in surgical resection of patients with peritoneal carcinomatosis are underway.

Abstract
Normothermic cardiopulmonary bypass (CPB) is used in cardiac surgery at some institutions. To compare hemodynamic and hormonal responses to hypothermic (29 degrees C) and normothermic nonpulsatile CPB, 20 adults undergoing coronary artery bypass graft and/or aortic valve replacement were studied. Hemodynamic measurements and plasma hormone concentrations were obtained from preinduction to the third postoperative hour. The two groups were given similar amounts of anesthetics and vasodilators. Systemic vascular resistance increased only during hypothermic CPB, and heart rate was higher at the end of hypothermic CPB. Postoperative central venous pressure and pulmonary capillary wedge pressure were lower after hypothermic CPB. Oxygen consumption decreased by 45% during hypothermic CPB, did not change during normothermic CPB, but increased similarly in the two groups after surgery; mixed venous oxygen saturation (SvO2) was significantly lower during normothermic CPB. Urine output and composition were similar in the two groups. In both groups, plasma epinephrine, norepinephrine, renin activity, and arginine vasopressin concentrations increased during and after CPB. However, epinephrine, norepinephrine, and dopamine were 200%, 202%, and 165% higher during normothermic CPB than during hypothermic CPB, respectively. Dopamine and prolactin increased significantly during normothermic but not hypothermic CPB. Atrial natriuretic peptide increased at the end of CPB and total thyroxine decreased during and after CPB, with no difference between groups. This study suggests that higher systemic vascular resistance during hypothermic CPB is not caused by hormonal changes, but might be caused by other factors such as greater blood viscosity. A higher perfusion index during normothermic CPB might have allowed higher SvO2.

Abstract
After an experimental study in dogs, authors report a new therapeutic device for peritoneal seedings (Intra-Peritoneal Chemo-Hyperthermia) and their preliminary results in five patients. They observed no mortality and no morbidity with this protocol using Mitomycin as antimitotic and hyperthermia as sensibilisation agent. This new technique means important technological and time investment but preliminary results appear to be encouraging and authors intend to standardize the present apparatus in order to go on using this device and obtain more experience.

Abstract
One new case of post-traumatic hematobilia due to an arteriobilary fistula is reported. This etiology is relatively rare, and its diagnosis is sometimes difficult if the three signs: pain, bleeding and jaundice are not observed. The most effective paraclinical examination still is selective arteriogrpahy, which makes the diagnosis possible, accurately locates the fistula and sometimes allows hyperselective embolization, as it did in this case. The use of embolization for the treatment of post-traumatic hematobilia due to an arteriobiliary fistula reduces operative mortality for this disease, which still has a poor prognosis.

Abstract
Since November 1985, we have performed 54 Intra-Operative Radiation Therapy (IORT) interventions, essentially in gastric cancer (20 patients) and in pancreatic cancer (22 patients). Mortality, morbidity, and average of survival rates were compared with a non-randomized control group: mortality and morbidity rates were similar in the two groups, with or without IORT. The follow-up period was too short for any valid conclusions about IORT in gastric cancer to be reached. However, in the case of unresectable pancreatic cancer, a significant difference was observed in survival rates when patients were treated by surgery alone or surgery and IORT (4.7 months), and when they were treated by surgery, IORT and external postoperative radiotherapy (8.9 months) (p less than 0.05). The study also examined the relief of abdominal and back pain in patients with unresectable pancreatic cancer: in our experience, survival was longer and more comfortable for patients treated with surgery and IORT. In conclusion, it appears that today IORT is without doubt a good palliative treatment for unresectable pancreatic cancer, but more experience is needed before a conclusion can be reached regarding resectable pancreatic cancer and gastric cancer.

Abstract
The authors describe their first experience of IP hyperthermochemiotherapy using mitomycin C under hypothermic coverage at 32 degrees C, in a female patient with peritoneal carcinosis secondary to stomach cancer. Postoperative complications were not observed. Tested mitomycin blood levels evidenced good absorption via the peritoneal route. 4 months later, the patient is doing well and the authors are propounding the method be started in a series of patients, in order to assess its long-term efficacy.

Abstract
Since November 1985, we performed Intra Operative Radiation Therapy in 53 cases, essentially in gastric cancer (20 patients) and in pancreatic cancer (22 patients). Mortality and morbidity were not increased by the use of Intra Operative Radiation Therapy. Our follow up is too short to get any valid conclusions about IORT in gastric cancer. However, for unresectable pancreatic cancer, we observed an improvement of the survey when patients were treated by "Surgery, IORT and External post operative radiotherapy". We also studied the relief of abdominal and back pain of unresectable pancreatic cancer: in our experience, the survey was longer and more confortable for patients treated with surgery and IORT. In conclusion it appears that today IORT is surely a good palliative treatment for unresectable pancreatic cancer, and longer experience is needed to conclude for resectable pancreatic cancer and for gastric cancer.

Abstract
Infection caused by Corynebacterium JK (CJK) has been recently described in immunocompromised patients. To evaluate the frequency of CJK infection among surgical and trauma intensive care patients, all patients with CJK isolations at clinical sites were reviewed. The criteria used were the presence of bacterial infection symptoms, isolation from significant sites and the efficiency of a vancomycin treatment. Eight patients were studied; 3 of them were considered infected, while 5 were judged only colonized. It is concluded that CJK infections can be a clinical problem in surgical trauma patients.
