RESUMO
BACKGROUND: Metabolic surgery is now considered as a therapeutic option in type 2 diabetes (T2D). However, few data are available regarding perioperative management of T2D. OBJECTIVES: To assess current practice among bariatric teams regarding perioperative management of T2D in order to propose guidelines. METHODS: A two-round Delphi method using online surveys was employed among bariatric teams experts (surgeons, diabetologists, anesthetists, nutritionists): first round, 63 questions covering 6 topics (characteristics of experts/teams, characteristics of patients, operative technique, pre/postoperative management, diabetes remission); second round, 44 items needing clarification. They were discussed within national congress of corresponding learned societies. Consensus was defined as ≥66% agreement. RESULTS: A total of 170 experts participated. Experts favored gastric bypass to achieve remission (76.7%). Screening for retinopathy, cardiac ultrasound, and reaching an HbA1c<8% are required in the pre-operative period for 67%, 75.3% and 56.7% of experts, respectively. After surgery, insulin pump should not be stopped, basal insulin should be halved, and bolus insulin should be stopped except if severe hyperglycemia. DPP-IV inhibitors and metformin are preferred after surgery. Patients should be seen by a diabetologist within one month if on oral antidiabetic agents (71.8% of experts), 2 weeks if on injectable treatments (77.1% of experts), and immediately after surgery if on insulin pump (93.5% of experts). Long-term monitoring of HbA1c is necessary even if diabetes remission (100%). CONCLUSION: Rapid postoperative modifications of blood glucose require a close monitoring and a prompt adjustment of diabetes medications.

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.

PURPOSE: There is confusion regarding the names, the number, and the exact location of the colonic arterial arches which provide connections between the superior and inferior (IMA) mesenteric arteries at the level of the left colic angle. The aim of this review was to delineate the "true" colic arches arising in the meso of the left colic angle and to describe their surgical implications. METHODS: A systematic review of the literature was performed using the MEDLINE database. The search included only human studies between 1913 and 2018. All dissection, angiographic, arterial cast and corrosion studies were analyzed. RESULTS: The terms "Riolan arch", "marginal artery of Drummond", "meandering mesenteric artery" and "Villemin's arch" must no longer be used in the scientific literature. Three arterial arches were found at the level of the left colic angle, permitting the communication between the two arterial mesenteric systems: (1) the Marginal Artery (the most peripheral, found in 100% of cases); (2) the "V" termination of the ascending branch of the left colic artery (LCA), existing in more than 2/3 of cases; and (3) the inter-mesenteric trunk, found more centrally located and existing in less than 1/3 of cases. CONCLUSIONS: Three arterial arches exist at the level of the left colic angle: (1) the Marginal Artery, (2) the "V" termination of the ascending branch of the LCA, and (3) the inter-mesenteric trunk. The knowledge of this anatomy is essential for performing colorectal surgeries involving ligation of the IMA.

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.

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.

Pelvic floor disorders include urogenital and anorectal prolapse, urinary and faecal incontinence. These diseases affect 25% of patients. Most of time, treatment is primarily surgical with a high post-operative risk of recurrence, especially for pelvic organ prolapse. Vaginal delivery is the major risk factor for pelvic floor disorders through levator ani muscle injury or nerve damage. After vaginal delivery, 20% of patients experiment elevator ani trauma. These injuries are more common in case of instrumental delivery by forceps, prolonged second phase labor, increased neonatal head circumference and associated anal sphincter injuries. Moreover, 25% of patients have temporary perineal neuropathy. Recently, pelvic three-dimensional reconstructions from RMI data allowed a better understanding of detailed levator ani muscle morphology and gave birth to a clear new nomenclature describing this muscle complex to be developed. Radiologic and anatomic studies have allowed exploring levator ani innervation leading to speculate on the muscle and nerve damage mechanisms during delivery. We then reviewed the levator ani muscle anatomy and innervation to better understand pelvic floor dysfunction observed after vaginal delivery.

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.

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.

BACKGROUND: Most dermatological conditions can be evaluated using validate clinical scores, no such tool is available for irritant contact dermatitis (ICD). OBJECTIVE: To create and validate a grid-based ICD severity score. METHODS: Three dermatologists developed the SCOre de REparation de l'EPIderme (SCOREPI) grid. Two studies were conducted to validate the SCOREPI. A cross-sectional study assessed the intra- and inter-observer error associated with using the SCOREPI. Each investigator received 15 min of training on proper use of the SCOREPI. A computer displayed a series of 20 photos of ICD, each of which were repeated three times in a randomized order. The prospective study assessed the correlation between SCOREPI with the severity of clinical symptoms as well as the sensitivity of the score to changes in ICD in response to topical treatment. RESULTS: The SCOREPI took an average of 35 ± 5 s to be completed and was characterized by an excellent intra-observer and moderate inter-observer reproducibility (intra-class correlation coefficient = 0.93 and 0.74, respectively). Significant divergence was observed between the physicians' assessment of estimated surface (P = 0.04), the presence of erythema (P < 0.0001) and the number of deep cracks (P = 0.0008). In the prospective analysis of patients, SCOREPI was correlated with tightness (r = 0.45; P < 0.0001), pain (r = 0.45; P < 0.0001), burning (r = 0.42; P < 0.0001), and pruritus (r = 0.28; P = 0.0055). SCOREPI decreased considerably during follow-up from 10.45 ± 4.61 to 4.82 ± 4.15 (P < 0.0001). CONCLUSION: The SCOREPI is easy to use, sensitive to change, and characterized by high intra- and moderate inter-observer reliability.

BACKGROUND: There is no demonstrated benefit of high-tie versus low-tie vascular transections in colorectal cancer surgery. OBJECTIVE: The aim of this study was to compare the effects of high-tie and low-tie vascular transections on colonic length after oncological sigmoidectomy, the theoretical feasibility of colorectal anastomosis at the sacral promontory, and straight or J-pouch coloanal anastomosis after rectal cancer surgery with total mesorectal excision. DESIGN: This study is an anatomical study on surgical techniques. SETTINGS: This study was conducted in a surgical anatomy research unit. PATIENTS: Thirty fresh nonembalmed cadavers were randomly assigned to high-tie and low-tie groups (n = 15). INTERVENTIONS: Oncological sigmoidectomy followed by total mesorectal excision was performed. MAIN OUTCOME MEASURES: The distances from the proximal colon limb to the lower edge of the pubis symphysis were recorded after each step of vascular division. RESULTS: The successive mean gains in length in high-tie vs low-tie vascular transections were 2.9±1.2 cm vs 3.1 ± 1.8 cm (p = 0.83) after inferior mesenteric artery division, 8.1 ± 3.1 cm vs 2.5 ± 1.2 cm (p = 0.0016) after inferior mesenteric vein division at the lower part of the pancreas, 8.1 ± 3.8 cm vs 3.3 ± 1.7 cm (p = 0.0016) after sigmoidectomy. The mean cumulative gain in length was significantly higher in high-tie vs low-tie vascular transections (19.1 ± 3.8 vs 8.8 ± 2.9 cm, p = 0.00089). After secondary left colic artery division, the gain in length was similar to that of the high-tie group (17 ± 3.1 vs 19.1 ± 3.8 cm) (p = 0.089). Colorectal anastomosis at the promontory and straight and J-pouch coloanal anastomosis feasibility rates were 100% in the high-tie group, 87%, 53%, and 33% in the low-tie group, but 100%, 100%, and 87% after secondary left colic artery division. LIMITATIONS: This anatomical study, based on cadavers rather than live patients, does not evaluate colon limb vascularization. CONCLUSIONS: The gain in colonic length is 10 cm greater for high-tie vascular transections. With low-tie vascular transections, high inferior mesenteric vein division produced a small additional gain in length, and secondary left colic artery division produced the same length gain as high-tie vascular transections.

The presence of a left hepatic artery (LHA) is an anatomical variation related to the persistence after fetal maturation of one of the two embryonic hepatic arteries, who disappear in the modal liver arterial vascularisation (liver vascularisation by a unique hepatic artery originating from the celiac trunk). When present, LHA is originating from the left gastric artery and runs through the pars condensa of the lesser omentum. Its frequency is varying from 12 to 34% according to the different study methods: 14 to 27% in anatomical series, 12 to 20% in angiographic studies and 12 to 24% in liver transplantation series. Laparoscopic detection has the highest sensitivity with reported rates from 18 to 34% of cases. LHA is irrigating a variable liver territory from a part of the left lobe to the whole liver in less than 1% of cases. A satisfactory knowledge of these anatomical variations is mandatory in liver surgery and during liver transplantation but also each time the pars condensa is approached during gastric surgery, hiatal surgery for gastroesophageal reflux and for bariatric surgery. Due to existing anastomosis between liver arteries, LHA ligation is feasible in most cases with a subsequent and transitory elevation of liver enzymes. On the contrary, in case of a unique LHA for the whole liver, the safety of its ligation is not demonstrated.

BACKGROUND: We compared pressure and volume-controlled ventilation (PCV and VCV) in morbidly obese patients undergoing laparoscopic gastric banding surgery. METHODS: Thirty-six patients, BMI>35 kg m(-2), no major obstructive or restrictive respiratory disorder, and Pa(CO(2))<6.0 kPa, were randomized to receive either VCV or PCV during the surgery. Ventilation settings followed two distinct algorithms aiming to maintain end-tidal CO(2) (E'(CO(2))) between 4.40 and 4.66 kPa and plateau pressure (P(plateau)) as low as possible. Primary outcome variable was peroperative P(plateau). Secondary outcomes were Pa(O(2)) (Fi(O(2)) at 0.6 in each group) and Pa(CO(2)) during surgery and 2 h after extubation. Pressure, flow, and volume time curves were recorded. RESULTS: There were no significant differences in patient characteristics and co-morbidity in the two groups. Mean pH, Pa(O(2)), Sa(O(2)), and the Pa(O(2))/Fi(O(2)) ratio were higher in the PCV group, whereas Pa(CO(2)) and the E'(CO(2))-Pa(CO(2)) gradient were lower (all P<0.05). Ventilation variables, including plateau and mean airway pressures, anaesthesia-related variables, and postoperative cardiovascular variables, blood gases, and morphine requirements after the operation were similar. CONCLUSIONS: The changes in oxygenation can only be explained by an improvement in the lungs ventilation/perfusion ratio. The decelerating inspiratory flow used in PCV generates higher instantaneous flow peaks and may allow a better alveolar recruitment. PCV improves oxygenation without any side-effects.

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.

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).

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.
