Abstract
INTRODUCTION Genital intraepithelial neoplasias (IEN) are precursors of squamous cell carcinoma. The ideal treatment must be efficacious, conservative and well-tolerated. CO2 laser is one of the recommended therapies, but its efficacy and safety have not been extensively studied. PATIENTS AND METHODS This was a retrospective single-center study. Sixteen patients (8 women and 8 men) treated with CO2 laser for genital IEN, whether high-grade or differentiated, were included. Surgical lateral margins of 3 to 5mm were taken macroscopically during treatment. The CO2 laser session, assessment of therapeutic response and follow-up were undertaken by a dermatologist at the University Hospital of Caen. RESULTS The mean patient age was 68.1 years and mean follow-up was 52.7 months (5-130). Lesions were isolated in 87.5% of patients. The recurrence rates of genital intraepithelial neoplasia after CO2 laser treatment were 58% for women and 40% for men. No impact on quality of life or on sexual activity was reported in over 90% of patients. CONCLUSION Whatever the treatment recommended for intraepithelial neoplasia, recurrence is frequent. CO2 laser is an effective and well-tolerated conservative therapeutic option. It enables rapid clinical remission, but as with all currently available treatments, long-term dermatologic follow-up remains necessary.

Abstract
BACKGROUND/OBJECTIVES Circulating phospholipids and sphingolipids are implicated in obesity-related comorbidities such as insulin resistance and cardiovascular disease. How bariatric surgery affects these important lipid markers is poorly understood. We sought to determine whether Roux-en-Y gastric bypass (RYGB), which is associated with greater metabolic improvement, differentially affects the phosphosphingolipidome compared with adjustable gastric banding (AGB). SUBJECTS/METHODS Fasting sera were available from 59 obese women (body mass index range 37-51 kg m-2; n=37 RYGB and 22 AGB) before surgery, then at 1 (21 RYGB, 12 AGB) and 3 months follow-up (19 RYGB, 12 AGB). HPLC-MS/MS was used to quantify 131 lipids from nine structural classes. DXA measurements and laboratory parameters were also obtained. The associations between lipids and clinical measurements were studied with P-values adjusted for the false discovery rate (FDR). RESULTS Both surgical procedures rapidly induced weight loss and improved clinical profiles, with RYGB producing better improvements in fat mass, and serum total cholesterol, low-density lipoprotein-cholesterol (LDL-C) and orosomucoid (FDR <10%). Ninety-three (of 131) lipids were altered by surgery-the majority decreasing-with 29 lipids differentially affected by RYGB during the study period. The differential effect of the surgeries remained statistically significant for 20 of these lipids after adjusting for differences in weight loss between surgery types. The RYGB signature consisted of phosphatidylcholine species not exceeding 36 carbons, and ceramides and sphingomyelins containing C22 to C25 fatty acids. RYGB also led to a sustained increase in unsaturated ceramide and sphingomyelin species. The RYGB-specific lipid changes were associated with decreases in body weight, total and LDL-C, orosomucoid and increased HOMA-S (FDR <10%). CONCLUSIONS Concomitant with greater metabolic improvement, RYGB induced early and sustained changes in phosphatidylcholines, sphingomyelins and ceramides that were independent of greater weight loss. These data suggest that RYGB may specifically alter sphingolipid metabolism, which, in part, could explain the better metabolic outcomes of this surgical procedure.

Abstract
PURPOSE Low-tie ligation in colorectal cancer surgery is associated with technical difficulties in left colic artery preservation. We aimed to evaluate and classify the anatomical and technical difficulties of left colic artery (LCA) preservation at its origin and along its route at the inferior border of the pancreas. METHODS A vascular reconstruction computed tomography prospective series of 113 patients was analyzed. The inferior mesenteric artery (IMA) branching pattern according to Latarjet's classification (Type I, separate LCA origin, Type II, fan-shaped branching pattern) and the distances between the IMA and the LCA origins and between the LCA and the Inferior mesenteric vein (IMV) at the inferior border of the pancreas were measured. RESULTS The IMA branching pattern was Type I in 80 (71 %) patients and Type II in 33 (29 %) patients. The IMA-LCA distance was 39.8 ± 12.2 mm. The LCA-IMV distance at the inferior border of the pancreas was 20.5 ± 21.7 mm. When classified based on this distance, 75 (66 %) patients were classified into the Near subgroup (<20 mm) (7.7 ± 4.1 mm) and 38 (34 %) into the Far subgroup (≥20 mm) (45.6 ± 20.4 mm, p < 0.001). A Type I subgroup F accounted for 27 % of the patients. CONCLUSIONS Left colic artery preservation is highly feasible at its origin in more than two-thirds of cases due to the separate origin. The addition of a high IMV ligation increases the risk of damage to the LCA at the inferior border of the pancreas because the distance to the IMV is less than 20 mm in two-thirds of cases.

Abstract
OBJECTIVES Despite the initial effectiveness of sleeve gastrectomy (SG), some patients who undergo this purely restrictive technique have inadequate weight loss or renewed weight gain and persistent obesity-related co-morbidities with their potentially lethal complications. In such patients, the conversion of SG by the addition of a malabsorptive technique may then be necessary. PATIENTS AND METHODS Conversion of SG to a mini gastric bypass (MGBP) was evaluated for failure of weight loss. An ante-colic end-to-side stapled gastro-jejunal anastomosis was performed laparoscopically, connecting the long narrow gastric tube to the jejunum at a point 200cm downstream from the ligament of Treitz. RESULTS Between October 2006 and February 2012, 651 laparoscopic MGBP were performed for morbid obesity. Twenty-three of these patients (3.5%) had previously undergone SG. The conversion from SG to MGPB was performed laparoscopically in 19 of the 23 patients (81%) at a mean interval of 26.3months (8.2-63.7). The 30-day postoperative mortality rate was zero and the morbidity rate was 9.5%. The mean BMI before MGBP was 44±7.7kg (35.8-55.4). Conversion of SG to MGBP resulted in additional weight loss, achieving a mean BMI of 39.9 with a 26.8% loss of excess BMI (EBL) at 3months, mean BMI of 36.5 with 37.2% EBL at 12months, mean BMI of 36.2 with 48.6% EBL at 18months, and mean BMI of 35.7 with EBL of 51.6% at 24months. The overall mean EBL was 57.3±19.5% (range: 25-82%) at 42.3months (range 16.7-60.8months). CONCLUSION Conversion of SG to MGBP is feasible, safe and effective, and results in significant additional weight loss. Definitive results at 2 and 5years are awaited for the long-term procedure validation.

Abstract
The subdiaphragmatic venous drainage of the embryo is provided by the two caudal cardinal veins to which is added the subcardinal vein system, draining the mesonephros, the perispinal supracardinal veins and the umbilical and vitelline venous system. The anastomosis of certain segments of the embryonic venous structures and the disappearance of others are at the origin of the inferior vena cava. Since the 19th century, three-dimensional reconstruction of solid models from histological sections were developed. At present, the development of computerized three-dimensional reconstruction techniques allowed to operate a multitude of techniques of image processing and modeling in space. Three-dimensional reconstruction is a tool for teaching and research very useful in embryological studies because of the obvious difficulty of dissection and the necessity of introducing time as the fourth dimension in the study of organogenesis. This method represents a promising alternative compared to previous three-dimensional reconstruction techniques including Born technique. The aim of our work was to create a three-dimensional computer reconstruction of the retrohepatic segment of the inferior vena cava of a 20mm embryo from the embryo collection of Saints-Pères institute of anatomy (Paris Descartes university, Paris, France) to specify the path relative to the liver and initiate a series of computerized three-dimensional reconstruction that will follow the evolution of this segment of the inferior vena cava and this in a pedagogical and morphological research introducing the time as the fourth dimension.

Abstract
In France, 1,000 obese persons per month undergo a bariatric operation. Obesity surgery requires coordination and monitoring of aftercare. The French public health-care insurer asked the medical associations involved in obesity management to provide guidelines for obesity surgery. The recommendations were developed by the national associations of Obesity, Nutrition and Diabetes: the Association Française d'Etudes et de Recherches sur l'Obésité (AFERO), member of the EASO and IASO; the Association de Langue Française pour l'Etude du Diabète et des Maladies Métaboliques (ALFEDIAM); the Société Française de Nutrition (SFN); and the Société Française de Chirurgie de l'Obésité (SOFCO). This article presents the short version of the guidelines.

Abstract
INTRODUCTION Verrucous epidermal nevus are benign epidermal hyperplasias. Their treatments are disappointing because of recurrences and anaesthetic scars. The aim of this study was to evaluate the efficacy of continuous carbon dioxide laser in the treatment of verrucous epidermal nevus. MATERIAL AND METHODS It was a retrospective study concerning all patients treated for epidermal verrucous nevus by carbon dioxide laser from 1991 to 2003. Several criteria were evaluated by the patients, a dermatologist and a staff (external observers). Aesthetic result, recurrences, pain due to treatment and global result were evaluated by the patients when they came back. RESULTS Twenty-one patients (12 F and 9 M), medium age 20.4, were evaluated with a 40.4 months follow-up (7 to 165 months). The epidermal verrucous nevus was situated on the neck or on the head for 62% of them (n = 13). Among these 21 patients, 86% (n = 19) estimated their skin as "cured" or "nearly normal" or "much improved". The rate was the same for the dermatologist. As for the staff, thanks to photos, only 53% of results were satisfying. The recurrences were never complete, but moderate in 38% of patients. Five patients, medium age 12,5, had hypertrophic scars. Among them, three were only partially hypertrophic. DISCUSSION A literature review has been made. Our satisfaction rates (nearly 90%) were slightly higher than other studies rates using carbon dioxide laser (74%) or other types of lasers (87%). The medium follow-up was longer than the one of other laser CO2 studies (26.7 months) or other lasers studies' (15.8 months). This study shows that continuous wave carbon dioxide laser is an easy and effective treatment of verrucous epidermal nevus. Aesthetic results are satisfying but moderate recurrences often occur. To prevent hypertrophic scars, we suggest to exclude teenagers.

Abstract
INTRODUCTION Aim of the present study was to analyze the medicoeconomic impact of each treatment for obesity in France, taking into account morbid obesity-associated comorbidities from a health insurance perspective and to calculate the cost-effectiveness ratio of SAGB compared to the non-surgical treatment for various kinds of patients, as well as the budget impact on a given cohort of patients. METHODS The model studied surgery-eligible patients and compared the effectiveness of the SAGB treatment to the conventional treatment. The follow-up extended from 1 to 5 years. Costs analyzed were treatment-related direct medical costs, as well as potential comorbidities costs. The effectiveness is determined according to the BMI loss and its maintenance over time, together with the level of improved quality of life. RESULTS An evaluation on a series of 1,000 patients shows that the treatment with SAGB is dominant (less expensive, more effective in terms of loss of BMI and its duration) compared to the conventional treatment for patients suffering from type II diabetes or obstructive sleep apnea. The same evaluation in terms of QALYs shows that the treatment with SAGB is dominant compared to the conventional treatment for patients with a BMI >or= 35 kg/m(2) and a type II diabetes, as well as for patients whose BMI >or= 40 kg/m(2) (with or without type II diabetes mellitus).

Abstract
BACKGROUND Dermatomyositis is a rare inflammatory dermatosis for which an iatrogenic origin has been described in very few cases. We report a case of dermatomyositis occurring after fluvastatin intake. CASE REPORT A 76-year-old male patient sought medical attention for a photodistributed rash and considerable muscular weakness present for one month. Two months earlier, fluvastatin had been introduced following the discovery of dyslipidemia. Serum creatine phosphokinase levels were elevated. Histological examination of a muscle biopsy was consistent with a diagnosis of dermatomyositis. Investigation for neoplasia and associated autoimmune disease proved negative. All clinical and laboratory abnormalities diminished spontaneously without recourse to corticosteroids within one month of the final intake of fluvastatin. After a follow-up period of three years, no recurrence was observed and no signs of neoplasia or connectivitis were found. DISCUSSION Iatrogenic dermatomyositis has only been reported in rare cases. Certain drugs have been incriminated, notably D-penicillamine. Six cases of drug-induced dermatomyositis have been described with statins: simvastatin, atorvastatin, pravastatin and lovastatin. Of these cases, only one resolved spontaneously after withdrawal of the drug alone without use of corticosteroids. Our case concerns intake of fluvastatin, an HMG-CoA reductase inhibitor with rare though well-known muscular side effects: elevated serum CPK, myalgia and rhabdomyolysis. Six cases of polymyositis have also been reported. Ours is the first case of dermatomyositis described with this category of statins. It is also the second reported case showing improvement after withdrawal of the lipid-lowering agent and without corticosteroids. Thus in cases of dermatomyositis, this iatrogenic picture should be sought routinely.

Abstract
BACKGROUND The increasing prevalence of morbid obesity together with the development of laparoscopic approaches has led to a steep rise in the number of bariatric operations. These guidelines intend to define the comparative effectiveness and surrounding circumstances of the various types of obesity surgery. METHODS A consensus panel representing the fields of general/endoscopic surgery, nutrition and epidemiology convened to agree on specific questions in obesity surgery. Databases were systematically searched for clinical trial results in order to produce evidence-based recommendations. Following two days of discussion by the experts and a plenary discussion, the final statements were issued. RECOMMENDATIONS After the patient's multidisciplinary evaluation, obesity surgery should be considered in adults with a documented BMI greater than or equal to 35 and related comorbidity, or a BMI of at least 40. In addition to standard laboratory testing, chest radiography, electrocardiography, spirometry, and abdominal ultrasonography, the preoperative evaluation of obesity surgery patients also includes upper gastrointestinal endoscopy or radiologic evaluation with a barium meal. Psychiatric consultation and polysomnography can safely be restricted to patients with clinical symptoms on preoperative screening. Adjustable gastric banding (GB), vertical banded gastroplasty (VBG), Roux-en-Y gastric bypass (RYGB) and biliopancreatic diversion (BPD) are all effective in the treatment of morbid obesity, but differ in degree of weight loss and range of complications. The choice of procedure therefore should be tailored to the individual situation. There is evidence that a laparoscopic approach is advantageous for LAGB, VBG, and GB (and probably also for BPD). Antibiotic and antithromboembolic prophylaxis should be used routinely. Patients should be seen 3 to 8 times during the first postoperative year, 1 to 4 times during the second year and once or twice a year thereafter. Outcome assessment after surgery should include weight loss and maintainance, nutritional status, comorbidities and quality-of-life.

Abstract
The median arcuate ligament is a tendinous arch joining the two medial borders of the diaphragm crura together. In 10-50% of subjects it is responsible for significant angiographic celiac trunk compression. In severe cases, a decrease in hepatic arterial blood flow with subsequent artery caliber reduction and reverse vascularization via the gastroduodenal artery is present. In liver transplantation, small-caliber hepatic arteries are higher risk factors for hepatic arterial thrombosis and frequent graft loss. We report a case of celiac trunk compression in a living-related donor and the two-step strategy we developed to perform a safer liver transplantation via flow-induced enlargement of the donor hepatic artery. A 29-year-old father was selected as a living-related liver donor for his 4-year-old daughter. Angiography revealed celiac trunk compression by the median arcuate ligament with reverse vascularization of the middle hepatic artery via the gastroduodenal artery, a proper hepatic artery 2 mm in diameter irrigating the left lateral segment exclusively, and a right hepatic artery irrigating the right lobe and segment 4. First-step division of the median arcuate ligament and gastroduodenal artery ligation were performed. Repeat angiography at the third week showed a 50% enlargement of the middle hepatic artery (3 mm). Second-step left lobectomy was performed at the fifth week. The transplantation was achieved with an arterial anastomosis between the middle hepatic arteries of donor and recipient. This two-step strategy including median arcuate ligament division provided flow-induced enlargement of the donor middle hepatic artery for a safer transplantation with arteries of more suitable calibers.

Abstract
BACKGROUND Laparoscopic application of an adjustable gastric band (LAGB) is considered the least invasive surgical option for morbid obesity. It has the advantage of being potentially reversible and can improve quality of life. METHOD Between April 1997 and January 2001, 400 patients underwent LAGB. There were 352 women and 48 men with mean age 40.2 years (16-66). Preoperative mean body weight was 119 kg (85-195) and mean body mass index (BMI) was 43.8 kg/m2 (35.1-65.8). RESULTS Mean operative time was 116 minutes (30-380), and mean hospital stay was 4.55 days (3-42). There was no death. There were 12 conversions (3%). 40 complications required an abdominal reoperation (10%), for perforation (n = 2), gastric necrosis (n = 1), slippage (n = 31), incisional hernia (n = 2) and reconnection of the tube (n = 4). We noticed 7 pulmonary complications (2 ARDS, 5 atelectasis) and 30 minor problems related to the access port. At 2 years, mean BMI had fallen from 43.8 to 32.7 kg/m2 and mean excess weight loss (EWL) was 52.7% (12-94). CONCLUSION LAGB is a very beneficial operation with an acceptable complication rate. EWL is 50% at 2 years if multidisciplinary follow-up remains assiduous. Surveillance for late anterior stomach slippage within the band is essential.

Abstract
STUDY AIM Esophageal squamous cell carcinomas are frequently associated with head and neck cancers. This retrospective study was conducted to compare the long-term outcome of the patients with a double cancer and of the patients with a solitary esophageal cancer after curative management. PATIENTS AND METHODS From 1989 to 1999, 114 patients with an esophageal carcinoma were included in the study. Among them, 52 had an associated head and neck cancer (metachronous: n = 17 and synchronous: n = 35). Curative treatment was achieved in all patients. The patients were divided in "solitary" and "associated" group. RESULTS Age, sex distribution, tumor location and histological findings were similar in the two groups. The esophageal resection was an esopharyngolaryngectomy (n = 13), a subtotal esophagectomy with cervical anastomosis (n = 92) and a Lewis-Santy esophagectomy with thoracic anastomosis (n = 9). Operative mortality (8 versus 7.7%), anastomotic leaks rate (14.5 versus 21%) and pneumonia rate (21 versus 9.6%) were not significantly different in the two groups. The mean hospital stay was 27 days. The mean follow-up was 85 +/- 50 months. Five-year survival rates were not significantly different in the two groups (p = 0.6411). In univariate survival analysis the only significant predictive factors were the depth of esophageal tumor invasion (p = 0.0002) and node involvement (p = 0.0373). The presence of head and neck cancer did not affect survival after esophagectomy. CONCLUSION With an aggressive therapeutic plan, the survival of patients with an esophageal cancer associated to head and neck cancer was similar to the survival of patients with an isolated esophageal carcinoma. Long term esophageal survey seems to be useful to detect more superficial esophageal carcinomas in patients with head and neck cancer.

Abstract
PURPOSE To evaluate if T2-weighted high-spatial-resolution magnetic resonance (MR) imaging (117 microm per pixel) can help accurate classification of atherosclerotic plaques. MATERIALS AND METHODS Thirty human arteries and 11 carotid endarterectomy specimens from 31 patients underwent T2-weighted MR imaging (2-T magnet; repetition time, 2,000 msec; echo time, 50 msec) at room temperature. After imaging, Bouin fixative was used to fix 26 arteries, and the other 15 arteries were fixed by means of freezing. Specimens were stained with hematoxylin-eosin and safranin or Sudan lipid stain. MR images and histologic slices were classified independently by two radiologists and a pathologist, respectively, on the basis of the American Heart Association classification. RESULTS Results with MR imaging were the following: type I-II plaques, sensitivity of 67% and specificity of 100%; type IV-Va plaques, sensitivity of 74% and specificity of 85%; type Vb plaques, sensitivity of 90% and specificity of 100%; type Vc plaques, sensitivity of 80% and specificity of 90%. No type III plaque was diagnosed in the study. The overall kappa value was 0.68. CONCLUSION High-spatial-resolution MR imaging with T2 weighting alone can help accurate classification of fibrocalcic plaques (type Vb), but it is subject to limitations for the classification and analysis of other types of atherosclerotic plaques.

Abstract
STUDY AIM Laparoscopic gastric banding for morbid obesity is noninvasive and reversible. The aim of this prospective study was to report the preliminary results of this procedure in the first 300 patients. PATIENTS AND METHODS From April 1997 to January 2000, 300 patients were laparoscopically operated for severe obesity: 266 women, 34 men, with a mean age of 40.1 years (range: 16-66). The mean preoperative weight was 118 kg (range: 85-195) and the mean body mass index (BMI) was 43.6 kg/m2 (range: 35.1-65.8). This is a recent and complete series with a mean follow-up of 10 months (range: 3-31). The primary endpoint was excessive weight loss (EWL) and the secondary endpoints were tolerance and morbidity. RESULTS There were no postoperative deaths. The mean operating time was 129 minutes (range: 50-380). A conversion to laparotomy was necessary in 11 patients. The mean hospital stay was 4.76 days (range: 3-42). There were 29 complications (9.6%), 16 among the first 50 procedures: 14 patients underwent an abdominal reoperation (2 perforations, 3 early slippages, 7 late slippages, 2 incisional hernias); 6 had respiratory complications with 2 ARDS and 9 developed a complication related to the port. At one year, BMI decreased from 43.6 to 33.7 kg/m2 and EWL reached 44.2%; 80% of the patients lost 60% of their excess weight. CONCLUSION Our experience is encouraging with an acceptable complication rate (5%) after 50 procedures. Slippage remains the main reason for close surveillance. Half of the excess weight can be comfortably lost in one year when the whole medical and surgical staff provide close support for each patient.

Abstract
Brainstem auditory evoked potentials (BAEP) are used routinely in clinical practice to evaluate the normality of the lower auditory system. The objective of this review is to describe the functional anatomy of the structures implicated in BAEP generation (cochlear nerve and the auditory brainstem nuclei). Indications and results of BAEP in clinical practice are presented and correlated with auditory structures, which generate each waveform of BAEP.

Abstract
OBJECTIVES The laparoscopic approach for gastroplasty is gaining widespread acceptance for morbid obesity. Less invasive and potentially reversible, this gastroplasty guarantees better quality of life. We thus evaluated perioperative complications in our consecutive series of 300 patients and followed the excessive weight loss (EWL) for the first 150. PATIENTS AND METHODS Between April 1997 and January 2000, 300 patients underwent laparoscopic gastroplasty for severe obesity according to the NIH criteria: 266 women, 34 men, mean age 40.1 years (16-66 years). Mean preoperative weight was 118 kg (85-195 kg) and mean body mass index (BMI) was 43.4 kg/m2 (31.5-65.8). Two hundred one patients had 1.3 comorbidity due to excess weight. The first 150 patients were followed 15.5 months (12-31) without any lost to follow-up. Medical, dietary and psychological data were recorded every 3 months for 18 months. The main evaluation criteria was EWL; others were tolerance and morbidity. RESULTS There was no death. Mean operative time was 129 minutes (50-380), mean hospital stay was 4.76 days (3-42). There were 11 conversions (3.6%). There were 29 complications (9.6%): 11 were postoperative (5 underwent an abdominal operation for 2 perforations, 3 early slippages; and 6 respiratory problems with 2 ARDS) and 18 were late complications (7 late slippages, 2 incisional hernias and 9 port problems). Follow-up of the first 150 patients was complete: at one year, BMI fell from 43.6 to 33.8 kg/m2 and EWL reached 50.5% at 18 months. CONCLUSION Our experience is recent, but in light of the danger of the spontaneous course of morbid obesity, the results are encouraging due to the absence of mortality and the low rate of complications after the first 50 procedures. Half of the excess weight can be lost in one and a half years. Patient comfort remains quite acceptable with the active support of the surgery and medical teams.

Abstract
OBJECTIVE The purpose of this study was to assess three-dimensional (3D) gadolinium-enhanced MR angiography, used alone or in association with duplex Doppler sonography, with a fast acquisition time (8 sec) for evaluating the extracranial carotid arteries. SUBJECTS AND METHODS In this prospective study, 48 successive patients with carotid artery stenoses were examined with 3D gadolinium-enhanced MR angiography and 3D time-of-flight MR angiography. Of the 44 eligible patients, conventional angiography was available in 33 and duplex sonography in 27. We used the North American Symptomatic Carotid Endarterectomy Trial technique to quantify stenosis on all angiograms, and a 250 cm/sec threshold at duplex sonography to diagnose stenoses greater than 70%. Image quality of 3D gadolinium-enhanced MR angiography and 3D time-of-flight MR angiography was assessed, as well as sensitivity and specificity for each technique alone and in combination with duplex sonography. Conventional angiography was the gold standard. RESULTS Three-dimensional gadolinium-enhanced MR angiography yielded good image quality in 90% of cases. When used alone, it yielded a sensitivity and a specificity of 94% and 85%, respectively, in screening stenoses greater than 70% (70-99%). When combined with duplex Doppler sonography, it provided a 100% sensitivity and specificity for detection of stenoses between 70% and 99% and would have obviated 61% of conventional angiography. In comparison, 3D time-of-flight MR angiography used alone yielded a sensitivity of 88% and a specificity of 94%. In combination with duplex Doppler sonography, its use would have obviated conventional angiography in 74% of cases. Three-dimensional gadolinium-enhanced MR angiography provided accurate results in the diagnosis of occlusions and ulcers and can visualize distant stenoses. CONCLUSION Used alone, 3D gadolinium-enhanced MR angiography is not accurate enough to replace conventional angiography in the evaluation of extracranial carotid arteries. In association with duplex Doppler sonography, however, it is accurate and may obviate a significant number of conventional angiographic examinations.

Abstract
OBJECTIVES Reduction of the weight in obese patients is a pre-condition for the aesthetic improvement of obesity or its after effects by plastic surgery. The aim of this study was to evaluate the effectiveness and advantages of gastric banding, using a ring positioned under laparoscopic guidance. PATIENTS AND METHODS Thirty-nine patients with morbid obesity were operated on. For the first nine patients, gastric restriction was obtained by Mason's traditional technique. In the remaining thirty, a Kuzmak ring was positioned a few centimeters under the cardia, under laparoscopic guidance. The study concerned the evolution of weight, associated pathologies, and complications. RESULTS Three months after surgery, all patients had lost weight (mean loss: 15 kg). At six months, a mean weight loss of 26 kg was observed. At one year, the mean weight loss was 35 kg. Two patients experienced postprandial vomiting that justified widening of the ring; one ring was poorly tolerated and was removed 10 days after surgery. CONCLUSION This new surgical technique is effective for reducing the weight of obese patients. The laparoscopic approach to the stomach reduces parietal complications and enables subsequent abdominal plastic surgery to be performed.

Abstract
An anastomosis between the common trunk of the middle and left hepatic veins of the receiver and the cranial portion of the inferior vena cava of the donor is one of the techniques for restoration of hepato-caval continuity in orthotopic liver transplantation. This technique avoids dissection of the retrohepatic vena cava and total caval clamping. The aim of this study was to define the feasibility of this technique by a morphologic and biometric study of the common trunk of the middle and left hepatic veins on the basis of 64 injection-corrosion hepatic specimens and 21 fresh subjects. A common trunk for the middle and left hepatic veins was present in 54 of 64 cases (84%) with a length of 3 to 17 mm. The diameter of the new ostium constructed by section 0.5 cm proximal to the junction of the middle and left hepatic veins was 23.9 +/- 2.3 mm, which approximated to that of the vena cava where it traversed the diaphragm (24.4 +/- 2.0 mm). These findings confirmed that restoration of hepato-caval continuity by anastomosis between the common trunk of the middle and left hepatic veins of the receiver and the cranial portion of the vena cava of the graft is possible without incongruence. This study makes no assumptions about the hemodynamic effects associated with the smallest diameter of the true ostium of the common trunk at its opening into the inferior vena cava. In this study, the morphology of the common trunk was comparable to that observed by Nakamura. Further, we propose an anatomo-clinical classification allowing evaluation of the facility of vascular control of the common trunk in terms of the number and location of the collateral veins.

Abstract
Portal hypertension is characterised by the development of a collateral portocaval circulation. Among these venous reroutings, some are situated posteriorly in the left subphrenic compartment. These are the spontaneous splenorenal and gastrorenal anastomoses. Their incidence is estimated at around 16%. On the one hand, there are the direct shunts, which anastomose the spelling v. to the left renal v., of an anecdotal nature, and on the other the spontaneous indirect splenorenal shunts, characterised by the presence of a complete neurovascular pedicle traversing the gastrophrenic ligament. This relates to the gastric collateral v., which is connected to the left renal v. via the inferior v. of the left crus of the diaphragm and the middle capsular v., hence the name "gastro-phreno-capsulo-renal shunt". At an advanced stage of portal hypertension these splenorenal shunts may acquire a major caliber and behave like actual surgical shunts.

Abstract
Congenital dilatation of the bile duct is an uncommon lesion requiring surgical treatment. Complete excision of the diseased bile duct prevents development of carcinoma of the bile duct. We report three cases of congenital dilatation of the biliary three, each illustrating a particular aspect of the therapeutic strategy. One patient had an unusual anomaly of the pancreaticobiliary junction that required pancreaticoduodenectomy. Another patient developed carcinoma of the bile duct 15 years after an internal derivation of a choledochal cyst. The last patient had dilatations of the common and intrahepatic bile ducts associated with congenital hepatic fibrosis.

Abstract
From January 1989 to December 1996, 56 consecutive patients underwent emergency surgery for occlusive cancer of the left colon. Excepting 12 patients whose symptomatology and radiographic presentation required medial laparotomy, the elective procedure was initial colostomy. There were 11 men and 33 women, mean age 76 years (range 50-97). Two patients in poor general status (ASA III) died during the postoperative period. Among the 42 survivors, the second procedure was not performed because of poor general status or disease progression in 6. Mean delay to the second procedure for resection was 11.5 days; during the same hospitalization for 32 out of 36 patients. The second procedure was segmentary colectomy in 34 cases and limited to exploratory laparatomy because of inextricable lesions in 2. Among the 34 re-operations with segmentary colectomy, the ostomy was removed in 28 at the second procedure and a third procedure was required in 6 cases. All the anastomoses in this series were sutured manually. Mortality for re-operation was nil. Pathology results (Duke's classification) in the 36 reoperated patients was: stage B = 3, stage C = 19, stage D = 14. In this series, operative mortality only concerned those patients whose condition was incompatible with selective surgery for colostomy. This risk cannot be lowered by any, other surgical approach. For the 34 resection-anastomosis elective operations, no major complications or deaths were observed. These results led us to recommend two stage surgery as routine strategy since survival of all those patients capable of sustaining an elective colostomy in an emergency setting can be assured.

Abstract
Total proctocolectomy followed by ileo-anal anastomosis with a reservoir is the operation of choice for the treatment of familial adenomatous polyposis and of certain forms of hemorrhagic proctocolitis. Vascular section is sometimes necessary to enable the extremity of the reservoir to reach the anal sphincter without traction. The aim of this study was to compare the gain in length obtained by two different techniques of vascular section and to assess in terms of the vascular anatomy of the last small intestinal loop which technique best preserved the vascularisation of the reservoir as a whole. Twenty-two fresh cadavers had an ileal J-shaped reservoir of 18 cm fashioned from the last loop of small intestinal loop after section of the root of the mesentery. The gains in length so obtained were measured after section of the ileocolic a. at its origin (group A) or section between the two vascular arches of the last small intestinal loop (group B); the superior mesenteric vessels were then injected with colored resin. The gain in length obtained by these two methods was identical (2.3 +/- 1.1 cm for group A as against 2.18 +/- 0.9 cm for group B), but only if the section of the ileocolic a. was accompanied by section of the mesenteric peritoneum up to the vascular arch formed by the anastomosis between the terminal branch of the superior mesenteric a. and the ileocolic a. The constancy of this anastomosis always allowed section of the ileocolic a. while preserving good vascular distribution to the entirety of the reservoir. Section between the two arches was difficult when the distance separating them was small.

Abstract
Laparoscopic techniques currently constitute an alternative proposed for the repair of hernias of the inguinofemoral region. Nerve injuries have led some teams to recommend technical principles based on the anatomical relations of these nerves with the subperitoneal fascia transversalis and inguinal fossae. An anatomical study consisting of dissection of nonembalmed cadavres, allowed, after evisceration, dissection of the lumbar plexus and its terminal branches, particularly those supplying the inguinofemoral region: iliohypogastric and ilio-inguinal nerves, the genitofemoral nerve, the femoral nerve and the lateral cutaneous nerve of the thigh. Via transperitoneal laparoscopy, the posterior surface of the anterior abdominal wall is centered on the deep inguinal ring, containing testicular vessels and the vas deferens. This deep inguinal ring receives the genitofemoral nerve. Medially, the anterior parietal peritoneum describes three folds formed by the outline of the epigastric artery, umbilical artery and urachus on the midline. The outline of Hesselbach's ligament separates the deep inguinal ring from Hesselbach's triangle, the zone of weakness of direct inguinal hernia. The iliac psoas muscle pass laterally underneath the inguinal ligament, while the external iliac vessels, subsequently becoming the femoral vessels, are located medially. Pectineal ligament lies on the posterior surface of the femoral ring between the umbilical artery and the epigastric artery. Installation of an abdominal wall prosthesis, either transperitoneally or retroperitoneally, must be centered on the deep inguinal ring, and its solid sutures are located medially to the pectineal ligament and anterior abdominal wall. On the other hand, the nerves at risk of being damaged are situated laterally: the ilio-inguinal and ilio-hypogastric nerves in the plane between external oblique and internal oblique above the anterior superior iliac spine, lateral cutaneous nerve of the thigh under the inguinal ligament close to the anterior superior iliac spine, genitofemoral nerve with the spermatic cord in the deep inguinal ring and femoral nerve underneath the inguinal ligament with the psoas muscle lateral to the external iliac artery. No stapling must be performed under the plane of the inguinal ligament to avoid damage to the femoral vessels and lateral to the deep inguinal ring to avoid nerve damage.

Abstract
Acalculous cholecystitis, a recognized manifestation of acquired immune deficiency syndrome (AIDS), causes abdominal pain which can be relieved by cholecystectomy. The indications for cholecystectomy have remained undefined, however, because the cholecystitis is usually accompanied by generalized cholangitis and it is difficult to distinguish the relative clinical importance of the two problems. Since 1985, we have performed cholecystectomy on 8 patients with AIDS who had clinical manifestations of acute cholecystitis associated with a thickening of the gallbladder wall by 5 mm to 12 mm. Two of the 8 had gallstones and 4 had associated cholangitis. All had been treated with antibiotics for 20 to 180 days before surgery, but physical deterioration had progressed in every case. At the moment of surgical intervention, 4 patients had multiple organ failure. One patient died 3 days postoperatively, but the rest recovered rapidly with resolution of the abdominal pain and sepsis. Two patients died 20 days after surgery due to complications of AIDS. The remaining 5 died due to AIDS at 6, 9, 10, 12, and 14 months after surgery. Two of this group developed progressive cholangitis with raised serum alkaline phosphatase. Our experience indicates that cholecystectomy should be considered for the treatment of severe and persistent symptoms of hepatobiliary manifestations of AIDS notwithstanding the presence of cholangitis.

Abstract
Cephalic pancreatoduodenectomy (CPD) with pylorus preservation has been suggested to improve the functional and nutritional result of surgery. At operation, the first two centimeters of the duodenum are preserved, the vascular arch of the lesser gastric curvature is saved and the right gastroepiploic artery is resected at its origin. The aim of this study on 15 fresh cadavers was to determine the origin of the vascularization of the remaining duodenum and also the possibilities of preserving an optimal vascularization after CPD and pylorus preservation. All of the arteries supplying the remaining duodenum and arising either from the right gastric artery or the right gastroepiploic artery were identified. The distances between the origin of the infrapyloric artery and the termination of the gastroduodenal artery on the cranial and ventral pancreaticoduodenal artery and the left gastroepiploic artery were measured. At CPD with pylorus preservation, the study demonstrated that: 1) the cranial side of the remaining duodenum remains vascularized in 80% of the cases by one or two supraduodenal branches coming from the right gastric artery; 2) ligation of the right gastroepiploic artery eliminates all vascular supply to the caudal side of the remaining duodenum in almost half of the cases; 3) in these cases, the dissection of the bifurcation of the gastroduodenal artery and the vascular section beyond the origin of the infrapyloric artery allowed a direct vascular supply to the remaining duodenum to be preserved.
