A preoperative cotininury test for abdominoplasty reduces peri-operative complications.

BACKGROUND: Smoking induces complications in plastic surgery, in particular wound healing delays. Despite a 4-weeks' abstinence asking before and after surgery, some patients denied or hid their consumption. The aim of this study was to evaluate the effectiveness of a cotininury detection test in terms of improvement in outcomes after an abdominoplasty. MATERIAL AND METHODS: This retrospective cohort study included patients who underwent an abdominoplasty with umbilical transposition and lipoaspiration. Current smokers were asked to stop smoking 4 weeks before and after surgery. After 2013, we performed a preoperative cotininury test for patients having abdominoplasty, with a cancellation of surgery in case of positive result. We analyzed the test's effectiveness on delayed healing and on other complications. RESULTS: Two hundred and thirty-five patients were included; 80 were tested and 21,3% had a positive test. There was significantly less delayed healing in the "screening" group than in the "no screening": 20,3% versus 41,5% (P=0,002). Alike, complications were significantly less frequent in the "screening" group than in the "no screening": 18,1% versus 42,3% (P<0,001). CONCLUSION: The routine use of the cotininury test in preoperative abdominoplasties significantly reduces risk of delayed healing and other serious complications. It is an objective test, which is simple, quick and non-invasive. Smoking cessation must be at least 4 weeks before and after the surgery. Following medical advice to cease smoking by the surgeon and anesthetist, referral to an appropriate tobacco-addiction specialist clinic may be helpful for the patient who has difficulty stopping smoking.

[Stretching and chylothorax]. / Stretching et chylothorax.

INTRODUCTION: Chylothorax is a rare cause of pleural effusion. The most common causes are iatrogenic or medical. We report an unusual and rare cause of bilateral chylothorax. CASE REPORT: A 73-year-old woman with no past history was admitted to the emergency department for sudden onset of dyspnoea. Chest X-ray and thoracic CT scan revealed large bilateral pleural effusions. Analysis of the fluid revealed a chylothorax. The patient was treated by chest tube drainage and a fat free (medium chain triglyceride) diet. This led to drying up of the effusions and rapid discharge. Complementary imaging examinations with chest-abdomen-pelvis CT, PET CT and pelvic MRI did not reveal any underlying cause. The final diagnosis was bilateral traumatic chylothorax caused by tearing of the thoracic duct during stretching exercises. CONCLUSION: Following a literature review, similar cases with the same clinical presentation were found. Combined treatment with thoracic drainage and medium chain triglyceride diet was effective in drying up the effusions. Our diagnosis was a diagnosis of exclusion. It is important to exclude a medical cause by thorough investigation.

[Thymomectomy by minimally invasive surgery. Comparative study videosurgery versus robot-assisted surgery]. / Traitement des thymomes par chirurgie mini-invasive. Étude comparative vidéochirurgie versus voie robot-assistée.

OBJECTIVES: To report the results of minimally invasive surgery in patients with stage I or II thymoma in the Masaoka classification. The reference technique is partial or complete thymectomy by sternotonomy. METHODS: A retrospective single-center study of a prospective database including all cases of thymoma operated from April 2009 to February 2015 by minimally invasive techniques: either videosurgery (VATS) or robot-assisted surgery (RATS). The surgical technique, type of resection, length of hospital stay, postoperative complications and recurrences were analysed. RESULTS: Our series consisted of 22 patients (15 women and 7 men). The average age was 53 years. Myasthenia gravis was present in 12 patients. Eight patients were operated on by VATS and 14 patiens by RATS. There were no conversions to sternotomy and no perioperative deaths. The mean operating time was 92min for VATS and 137min for RATS (P<0.001). The average hospital stay was 5 days. The mean weight of the specimen for the VATS group was 13.2 and 45.7mg for the RATS group. Twelve patients were classified Masaoka stage I and 10 were stage II. According to the WHO classification there were 7 patients type A, 5 type AB, 4 type B1, 4 type B2 4 and 2 type B3. As proposed by the Group ITMIG-IASLC in 2015 all patients corresponded to group I. The mean follow-up period was 36 months. We noted 3 major perioperative complications according to the Clavien-Dindo classification: one pneumonia, one phrenic nerve paralysis and one recurrent laryngeal nerve palsy. We observed one case of local recurrence at 22 months. Following surgery 4 patients were treated with radiotherapy and 2 patients with chemotherapy. CONCLUSIONS: The minimally invasive route is safe, relatively atraumatic and may be incorporated in the therapeutic arsenal for the treatment of Masaoka stage I and II thymoma as an alternative to conventional sternotomy. RATS and VATS are two minimally invasive techniques and the results in the short and medium term are acceptable. The clinical advantages of one over the other are sifficult to establish. RATS could handle larger and more complex lesions in view of the weight and size of the operating instrument.

[Implementation of a robotic video-assisted thoracic surgical program]. / Mise en place d'un programme de chirurgie thoracique mini-invasive robot-assistée.

AIMS: Recent publications from North America have shown the benefits of robot-assisted thoracic surgery. We report here the process of setting up such a program in a French university centre and early results in a unit with an average treatment volume. METHODS: Retrospective review of a single institution database. The program was launched after a 6-month preparation period. RESULTS: From January 2012 to January 2013, totally endoscopic, full robot-assisted procedures were performed on 30 patients (17 males). Median age was 54 [Q1-Q3, 48-63] years and ASA score 2 [1,2]. Operative procedures included thymectomy (9 ; 30%), lobectomy with nodes resection (11 ; 38%), segmentectomy (4 ; 14%), lymphadenectomy (3 ; 10%), Bronchogenic cyst (2, 5%) and posterior mediastinal mass resection (1 ; 3%). No conversion was required. Median blood loss was 50mL [10-100]. Median operating time was 135 min (105-165) including 30 min [20-40] for docking, 90min for robot-assisted operating [70-120] and 15 min [10-15] for lesion extraction. CO2 insufflation was used in 28 cases (93%). Hospital stay was 4 days [4-6] with 6 minor complications (20%) (Grade 1 according to the Clavien-Dindo classification). After a median 4 months follow-up [2-7], all patients were alive and demonstrated a good quality of life. CONCLUSION: This series suggests that full robotic thoracic procedures are safe and effective treatment for various pathologies, with low morbidity and without a significant learning curve, even in a lower volume centre. This technology should accompany the development of minimally invasive thoracic surgery. The importance of robotic training should be emphasized to optimize procedures and costs.

Endoscopic injection of adrenaline for severe peptic ulcer haemorrhage in high surgical risk patients.

Endoscopic adrenaline-hypertonic injection was attempted in 40 patients admitted for oesophagogastroduodenal ulcer haemorrhage unresponsive to conventional medical treatment and presenting with severe underlying disease or advanced age (less than 80 years). The results were compared with our own historical controls (43 patients) treated by conventional therapy, meeting the same inclusion criteria. Permanent haemostasis was achieved in 32 patients in the injection group and 30 in the control group (NS) but emergency surgery was less frequent in the injection group (2 vs 25, p less than 0.001). Blood transfusion requirements were less in the injection group (8.5 +/- 6.2 vs 10.2 +/- 5.4, p less than 0.05) but length of hospital stay was not really different (15.7 days +/- 9.3 vs 20.9 +/- 14.4). Unfortunately, mortality was not reduced in the injection group (14/40 vs 17/43). Two lethal complications attributable to injection treatment occurred. This treatment could represent an alternative to conventional haemostatic treatment in high surgical risk patients with severe clinical bleeding, avoiding emergency surgery. In spite of the fact that we selected high-risk patients, endoscopic treatment was not able to lower the mortality (about 37%). Due to severe unpredictable side effects and potential risks of long-term massive rebleeding, this treatment should be performed electively in patients with severe clinical bleeding, as first line treatment when surgical risk factors exist or immediately before surgery in low risk patients.

Should the vagus nerves be isolated from the fundoplication wrap? A prospective study.

OBJECTIVE: To assess whether careful dissection and isolation of vagus nerves from the three-quarter Nissen fundoplication wrap (a periesophageal posterior gastric wrap 270 degrees in circumference) could modify the postoperative outcome and reduce postoperative gastric emptying disturbances. DESIGN: Open randomized control trial. SETTING: University hospital. PATIENTS: Forty-two patients with proved esophageal reflux and indication for surgery, after informed consent. INTERVENTIONS: A three-quarter Nissen fundoplication with (21 cases) or without (21 cases) dissection and exclusion of vagus nerves from the wrap. MAIN OUTCOME MEASURES: Standard questionnaire, acid reflux test, and gastric emptying study before and 3 months after surgery. RESULTS: No difference was found between the groups. There was a correlation between preoperative and post-operative gastric emptying. CONCLUSION: Exclusion of the vagus nerves from the three-quarter Nissen fundoplication wrap provides no advantage on postoperative gastric emptying and does not affect outcome of reflux surgery.

Thoracoscopic splanchnicectomy for control of intractable pain in pancreatic cancer.

BACKGROUND: Pain is the most distressing feature of pancreatic cancer. Thoracoscopic splanchnicectomy, first performed in 1993, has caused a resurgence of interest in surgical treatment of such excruciating pain. METHODS: Twenty patients underwent splanchnicectomy for pancreatic cancer pain over a period of 50 months. All were opiate dependent and unable to pursue normal daily life activities. We evaluated the type of splanchnicectomy performed and the long-term results procured. RESULTS: The number of splanchnicectomies was 24: unilateral videothoracoscopic splanchnicectomy, n = 11; unilateral videothoracoscopic splanchnicectomy with associated vagotomy, n = 5; and bilateral videosplanchnicectomy, n = 4. There was no postoperative complication. Pain was totally relieved and drug addiction stopped in 16 patients: 10 with unilateral videothoracoscopic splanchnicectomy, 2 with unilateral videothoracoscopic splanchnicectomy and associated vagotomy, and 4 with bilateral videosplanchnicectomy. Pain was not relieved after 4 unilateral videothoracoscopic splanchnicectomies, but bilateralization was not attempted in that subgroup. CONCLUSIONS: Unilateral videothoracoscopic splanchnicectomy is the treatment of choice of intractable pancreatic pain, affording drug cessation and recovery of daily activity in most patients. Failure may be treated secondarily by bilateralization with excellent results. Bilateral videosplanchnicectomy need not be performed by first intention.

Roux-en-Y limb motility after total or distal gastrectomy in symptomatic and asymptomatic patients.

BACKGROUND: The aims of this study were to compare Roux-en-Y limb motor patterns after total or distal gastrectomy, and to identify possible motor differences between symptomatic and asymptomatic patients. The usefulness of preoperative recording was also investigated. STUDY DESIGN: Sixteen patients were enrolled in the study, 10 patients after total gastrectomy (TG group) and 6 patients after distal gastrectomy (DG group). In 6 of 10 patients in the TG group, recordings were obtained before and after operation. Manometric recordings in the limb lasted 6 hours in all patients, 3 hours during fasting, and 3 hours after a 750-kcal meal. An intravenous injection of trimebutine (100-mg i.v.) was systematically administered at the end of each recording session. Motor results of the patients were compared with those obtained in the intact jejunum of 20 healthy controls. RESULTS: After operation, when patients were compared with controls, phase III (ie, regular activity of the migrating motor complex) was more frequent and more often incompletely propagated (5 of 16 patients versus 1 of 20 controls, unadjusted p < 0.05) and was significantly slower (p < 0.01 versus controls). Intravenous trimebutine induced phase III in 12 of 16 patients within a mean of 8.8 +/- 1 (SEM) minutes, longer than in controls (delay < 2 minutes). The fed pattern was shorter than in controls in both TG and DG groups, and the postprandial area under the curve during successive 30-minute periods was reduced in the DG group compared with controls (p < 0.01). In patients investigated before gastrectomy, motor parameters were not different from those of controls. Surgery resulted in an increased number of phase IIIs and a decreased migration velocity (p < 0.01) of phase III, a longer delay in response after trimebutine (p < 0.0001), and a reduced postprandial motor response (p < 0.01). After the operation, 4 of 10 patients in the TG group and 5 of 6 patients in the DG group were symptomatic. Symptomatic patients had slower and more often incompletely propagated (p < 0.01) phase III compared with asymptomatic patients. CONCLUSIONS: Roux-en-Y limb reconstruction mainly disturbs phase III propagation and the motor response to a meal. Motor changes are more marked after DG than after TG. Disturbed phase III propagation is the main difference between symptomatic and asymptomatic patients. Successful induction of phase III with trimebutine after gastrectomy and Roux-en-Y reconstruction indicates maintenance of encephalinergic mechanisms.

Upper jejunal motility after pancreatoduodenectomy according to the type of anastomosis, pancreaticojejunal or pancreaticogastric.

BACKGROUND: The goal of this study was to compare upper jejunal motor patterns after Billroth II pancreatoduodenectomy according to the type of pancreatic anastomosis (pancreaticojejunostomy [PJA] or pancreaticogastrostomy [PGA]) and the presence or absence of postoperative symptoms. STUDY DESIGN: Manometric recordings during fasting and after a 750-kcal meal were performed in the afferent limb in 12 patients (7 PJA, 5 PGA) and in the efferent limb in 15 other patients (7 PJA, 8 PGA) with a postoperative delay of 15+/-6 days and 3.9+/-2.2 months respectively. Patient data were compared to those of 20 healthy controls. RESULTS: During fasting, the 2 main abnormal findings were a higher incidence (p < 0.05) and a slower migration velocity (p < 0.01) of incomplete phase III by comparison with that recorded in controls. No difference for phase III was observed between the 2 surgical procedures regardless of recording site. Trimebutine, 100 mg intravenously, induced a phase III in 89% (24 of 27) of the patients. Delay of motor response varied from 5 to 10 minutes without difference between the recording site; it was less than 2 minutes in 100% of controls. Trimebutine-induced phase III showed similar propagation abnormalities to the spontaneous phase III. Duration of the fed pattern (p < 0.001) and motor index (p < 0.001) were significantly lower than in controls after the meal, in both limbs, whatever the type of anastomosis. Differences between the 2 surgical procedures were a slower migration velocity of phase III (p < 0.01) and a lower postmeal motor index (p < 0.05) in the efferent limb after PJA than after PGA. Nine of 27 patients were symptomatic. In these 9 patients, mean phase III migration velocity was slower (p < 0.001), and mean area under the postprandial curve was higher (p < 0.01) than in asymptomatic patients. Propagated clusters of contractions were only found in symptomatic patients and in the afferent limb. CONCLUSIONS: Pancreatoduodenectomy is associated with significant motor disturbances, mainly slower phase III and a reduced fed pattern, in the upper jejunum, at least during the first 3 postoperative months. Few motor differences were observed between PGA and PJA pancreatic anastomosis. A lesser occurrence of postsurgical motor anomalies does not appear to be an argument for preferring PGA to PJA.

Pre-operative kinetic parameter determination of colorectal adenocarcinomas. Prognostic significance.

BACKGROUND: The aim of this study was to test the prognostic value of pre-operative assessment of tumour kinetics in colorectal adenocarcinoma. METHODS: The study of tumour kinetics was performed using an in vivo injection of bromodeoxyuridine. Endoscopic biopsies were obtained from the tumour and analysed using flow cytometry. This procedure enables calculation of the in vivo S-phase fraction labelling index (LI), the duration of S-phase (Ts) and the potential tumour doubling time (Tpot). Disease-free survival curves were calculated by a Kaplan-Meier method. The statistical significance between curves was tested by the log rank test. A multivariate analysis was performed using the Cox's proportional hazards model to determine the effect of pathological staging (lymph node involvement), ploidy and kinetic parameters. RESULTS: Thirty-eight colorectal carcinomas were studied without prior chemotherapy or radiation therapy. In univariate analysis, lymph node involvement, labelling index > 10% and Tpot < 5 days were associated with poor prognosis, with P= 0.0006, 0.049 and 0.029 respectively; no significant differences were found in Ts (P = 0.214), and ploidy (P= 0.095). In multivariate analysis, lymph node involvement, ploidy and Tpot were found to be independent factors of colorectal cancer prognosis (P= 0.028, 0.032 and 0.035 respectively) in all tumours. Tpot was considered a independent prognostic factor in diploid tumours (P= 0.047) but not in aneuploid tumours (P= 0.345). CONCLUSIONS: These results suggest that kinetic parameters determined by pre-operative biopsies of colorectal adenocarcinoma represent a prognosis factor, independent of pathological staging, particularly in diploid tumours.

Effect of radiation therapy on the potential doubling time of tumours in colorectal cancers.

OBJECTIVE: The aim of the present study was to investigate the effects of standard fractionated radiation therapy on the kinetic parameters of colorectal adenocarcinomas. METHODS: The study of tumour kinetics involved in vivo injection of bromodeoxyuridine. Endoscopic biopsies were obtained from the tumour and analysed with flow cytometry. This procedure provides a rapid calculation of qualitative parameters such as ploidy and quantitative parameters such as the in vivo S-phase fraction labelling index which indicates the percentage of cells that have entered into the cycle, the duration of S-phase (Ts) and the potential tumour doubling time (Tpot). RESULTS: Thirty-eight colorectal carcinomas were studied without prior chemotherapy or radiation therapy (group 1) and ten rectal carcinomas were studied following radiation therapy (group 2). In diploid tumours, the labelling index was significantly lower in the post-radiotherapy group than in the pre-radiotherapy group (2.7 +/- 1.1% versus 6.4 +/- 4.2%, respectively; P= 0.01), and the Tpot was significantly longer after radiotherapy (group 2) (22.0 +/- 7.0 days versus 8.6 +/- 6.0 days, P = 0.002). Standard fractionated radiation therapy also appears to result in a longer Tpot in diploid adenocarcinomas of the colon and rectum. This effect was not observed in aneuploid tumours. CONCLUSIONS: The effectiveness of hyperfractionated schedules of radiation therapy for aneuploid rectal tumours with short Tpot warrants further investigation in a larger patient population.

Laparoscopic treatment of pancreatic pseudocysts.

BACKGROUND: A multicentric study was performed to evaluate the clinical results after laparoscopic treatment of pancreatic pseudocysts (PP). METHODS: We collected the data of 17 patients presenting with PP and operated on by laparoscopy between 1996 and 2001. There were nine men and eight women with a median age of 42 years (range 30-72). In 15 patients the PP developed after acute pancreatitis and the median delay between the acute onset and surgery was 7 months (range: 2-24). In two patients the PP was associated with chronic pancreatitis. All the patients had a single PP with a median diameter of 9 cm (range: 5-20). RESULTS: According to the location of the PP, a cystogastrostomy was performed in 10 patients and a cystojejunostomy in seven patients. The median operative time was 100 min (range: 80-300). Laparoscopic PP surgery was completed successfully in 16 patients and the median size of the cystoenterostomy was 3 cm (range: 2-5). Necrotic debris was present within the PP in 11 patients. The median postoperative hospital stay was 6 days (range: 4-24). No mortality and no immediate morbidity were recorded. However, two patients were readmitted within the first 3 postoperative weeks because of secondary PP infection. The first patient had an early closure of cystogastrostomy and was treated by endoscopic placement of a stent. The second represented with a right retrocolic abscess after cystojejunostomy and was treated by percutaneous drainage. One patient was lost for follow-up 2 months after surgery. The others had regular clinical and radiological controls. With a median follow-up of 12 months (range: 6-36), no recurrence of PP was observed. CONCLUSIONS: The laparoscopic treatment of PP was associated with a low postoperative complication rate and an effective permanent result. That approach avoided some difficulties, particularly bleeding that is classically linked with endoscopic internal drainage.

Cell proliferation in colorectal adenocarcinomas: comparison between Ki-67 immunostaining and bromodeoxyuridine uptake detected by immunohistochemistry and flow cytometry.

We compared three different means of assaying tumor proliferative activity in 30 human colorectal adenocarcinomas labeled in vivo with bromodeoxyuridine (BrdUrd). The labeling indices (LI) of BrdUrd obtained both by flow cytometry (FCM) and immunohistochemistry (IH) were also compared with the labeling index of Ki-67. These methods were then related to tumor ploidy and pathological features. Flow cytometry was performed in accordance with Begg's method after intravenous infusion of BrdUrd four hours before surgery. Immunohistology was carried out on paraffin-embedded sections with monoclonal antibodies against BrdUrd and Ki-67. A positive correlation was found between BrdUrd LI obtained by both FMC and IH (p<0.0001), a finding that complies with the literature. However, we report on a correlation between Ki-67 LI and BrdUrd LIs in colorectal tumors (p=0.012). The results were valid for all tumors when they were subdivided into diploid and aneuploid groups. The labeling indices were significantly higher in the aneuploid tumor group than in the diploid group (p=0.047). No relationship between proliferation parameters and tumor stage or grade was found. To our knowledge, this is the first report on a positive correlation between tumor proliferation indices in BrdUrd LIs and Ki-67 in colorectal carcinomas. This finding validates the value of Ki-67 immunostaining, which, however, should be confirmed in a larger series under the same technical conditions.

Resection of the aorta for leiomyosarcoma of the inferior vena cava.

Two cases of infra renal vena cava leiomyosarcoma are reported. Their locoregional extension resulted in a joint resection of the aorta and the vena cava. The follow-up of the two cases is of respectively 34 months and 32 months. We think that large resections are necessary, due to the microscopic characteristics of such tumors in order to try to improve the prognosis.

Achalasia: the case for primary laparoscopic treatment.

Laparoscopic Heller myotomy offers the best-known surgical therapy for esophageal achalasia. Nevertheless, this procedure continues to compete with alternative endoscopic treatment and is often considered only as a secondary resort. In this study, the authors performed a review of the results of laparoscopic Heller myotomy and an evaluation of the impact of previous endoscopic treatment regarding perioperative complications and late results. Twenty-seven patients with achalasia confirmed by a manometry examination underwent a primary laparoscopic Heller myotomy (group 1, n = 14) or experienced endoscopic treatment failure (group 2, n = 13). A dysphagia score (0-4) was obtained before and after surgery. Clinical course was reviewed at 2 months and then every 6 months after surgery. In December 1999, patients answered a questionnaire regarding surgery satisfaction, postoperative reflux, and dysphagia for statistical analysis. There were no deaths. Mean hospital stay was 5.6 days. Three perforations occurred in group 2 (25%) versus one in group 1 (6%) (not statistically significant). At a mean 27-month follow-up, the dysphagia score was significantly (P < 0.001) improved in both groups but more significantly in group 1 versus group 2 (not statistically significant). Only one patient in group 2 reported heartburn. All patients in group 1 (100%) were satisfied with surgery as opposed to 10 of 13 patients (75%) in group 2 (P < 0.10). Primary laparoscopic Heller myotomy appears to be the treatment of choice for achalasia. Previous endoscopic treatment increases intraoperative complications and may affect long-term results.

[Collis's operation for brachyesophagus. (49 patients)]. / L'opération de Collis pour brachyoesophage. (49 patients).

The results of infradiaphragmatic Collis' gastroplasty for the treatment of gastroesophageal reflux associated with acquired short brachyesophagus (Barrett's esophagus) were prospectively studied in 49 patients (50 operations). Clinical and endoscopic findings, and 3-hour postprandial pH measurement including Kaye's score were evaluated at short (3 to 8 months), medium (1 to 4 years), and long-term (more than 4 years) for all patients. Postoperative morbidity was 16 percent; there were 3 deaths (6 percent). Short term results, evaluated in 45 patients, were considered satisfactory in 30, poor (pyrosis and esophagitis) in 2, and incomplete (pyrosis without esophagitis in 2, dysphagia in 5, mild esophagitis in 6) in 13. Long term results (32 patients) were satisfactory in 24, poor in 5, and incomplete in 3 (pyrosis without esophagitis in one, gastric outlet disorder in 2). Long term pH measurements were obtained in 21 patients: 3 out of 6 patients with high scores had clinical or endoscopic signs of esophagitis. Analysis of late results showed that: a) satisfactory short term outcome was maintained in all but 2 patients (deterioration was observed in one patient 4 years later because of aggressive treatment for terminal bronchopulmonary carcinoma; the other was observed 5 years later after steroid therapy for aspergilloma with severe asthma); b) pH scores were variable in 11 patients. This variability and discordance of pH measurements was most likely due to the presence of acid secretion above the new esogastric junction, which was observed in half of the cases. We conclude that Collis' gastroplasty provided good results in Barrett's esophagus and might be compared to duodenal diversion in ulterior studies in this setting.

[Neuroma of the common bile duct: a rare cause of jaundice]. / Névrome de la voie biliaire principale: une cause rare d'ictère.

We report a case of neuroma of the main bile duct arising twenty years after cholecystectomy. The patient, a 82-year-old woman, was admitted for jaundice. Endoscopic retrograde cholangiography showed a regular stenosis of the main bile duct. Histologic examination demonstrated neuroma. Based on the analysis of this and 15 other previously published cases, the following features of bile duct neuroma were outlined: a) variable interval between cholecystectomy and the onset of jaundice (6 months to 35 years); b) the generally complicated postoperative course, c) the various localizations on the biliary tree (cystic, main bile duct, intrahepatic bile duct) and, d) the circumstances of onset.

[Inflammatory abdominal aortic aneurysm. Role of corticosteroid therapy]. / Anévrismes inflammatoires de l'aorte abdominale. Place de la corticothérapie.

For more than 20 years it has been generally acknowledged that operation for inflammatory abdominal aortic aneurysm (IAAA) using the common in-lay-graft procedure will induce the regression of peri-aortic fibrosis. However in prospective studies, after a 2 years follow-up, no regression appeared in approximated 8% of the cases (table I). Moreover in some IAAA a corticosteroid treatment (CS) was prescribed and it produced a regression of fibrosis and therefore facilitated the operation. Nevertheless the usefulness of the CS remains debated. We report 4 new cases of IAAA with CS. Based on our cases and an analysis of the literature we conclude that when there is no urgency to operate (diameter inferior to 50 mm) CS is the best option in IAAA with either severe inflammation or ureter involvement. Due to the regression of the fibrosis it can facilitate the surgical procedure. However it needs to be conducted with an adequate dose and duration. Finally the CS is the only possibility when the inflammation persist following the treatment of the IAAA.

["Natural history" of arterial surgical restoration below the inguinal region]. / "Histoire naturelle" des restaurations artérielles chirurgicales à l'étage sous-inguinal.

Infra-inguinal endarterectomy and by-pass (PSI) are the oldest and more frequently done restorative arterial operations. Here are described the evolution of patients, limbs and PSI and the factors that could interfere with them from the facts gathered since 30 years in literature. Prognosis is serious.

[Multiple intracranial aneurysms in relation to Recklinghausen's disease. Report of a case]. / Anévrysmes intracraniens multiples en rapport avec une maladie de Recklinghausen. A propos d'un cas.

Recklinghausen disease which usually appears by tumors of the nervous system peripheral and central can present anomalies of other systems, particularly vascular anomalies. The damage of renal arteries is well known. Intracerebral aneurysms are rare. Multiple intracerebral aneurysm has been reported in only four cases. We report a case of a patient presenting three intracerebral aneurysms. The patient died of a meningial haemorrhage. This leads us to search for intracerebral aneurysms in Recklinghausen's disease, specially in presence of arterial hypertension.
