Predictive factors of success at the French National Ranking Examination (NRE) : a retrospective study of the student performance from a French medical school
Background
The national ranking examination (NRE) marks the end of the second cycle (6th university year) of French medical studies and ranks students allowing them to choose their specialty and city of residency. We studied the potential predictive factors of success at the 2015 NRE by students attending a French School of Medicine.
Methods
From March 2016 to March 2017, a retrospective study of factors associated with the 2015 NRE success was conducted and enrolled 242 students who attended their sixth year at the school of medicine of Reims. Demographic and academic data collected by a home-made survey was studied using univariate and then multivariate analysis by generalized linear regression with a threshold of p <â 0.05 deemed significant.
Results
The factors independently associated with a better ranking at the NRE were the motivation for the preparation of the NRE (gain of 3327â±â527 places, p <â 0.0001); to have participated in the NRE white test organized by la Revue du Praticien in November 2014 (gain of 869â±â426 places, p <â 0.04), to have participated in the NRE white test organized by la confĂ©rence Hippocrate in March 2015 (+â613 places ±297, pâ<â 0.04). The factors independently associated with poor NRE ranking were repeating the first year (loss of 1410 places ±286, pâ<â 0.0001), repeating a year during university course (loss of 1092 places ±385, p <â 0.005), attendance of hospital internships in 6th year (loss of 706 places ±298, p <â 0.02).
Conclusions
The student motivation and their white tests completion were significantly associated with success at the NRE. Conversely, repeating a university year during their course and attendance of 6th year hospital internships were associated with a lower ranking
2020 WSES guidelines for the detection and management of bile duct injury during cholecystectomy.
Bile duct injury (BDI) is a dangerous complication of cholecystectomy, with significant postoperative sequelae for the patient in terms of morbidity, mortality, and long-term quality of life. BDIs have an estimated incidence of 0.4-1.5%, but considering the number of cholecystectomies performed worldwide, mostly by laparoscopy, surgeons must be prepared to manage this surgical challenge. Most BDIs are recognized either during the procedure or in the immediate postoperative period. However, some BDIs may be discovered later during the postoperative period, and this may translate to delayed or inappropriate treatments. Providing a specific diagnosis and a precise description of the BDI will expedite the decision-making process and increase the chance of treatment success. Subsequently, the choice and timing of the appropriate reconstructive strategy have a critical role in long-term prognosis. Currently, a wide spectrum of multidisciplinary interventions with different degrees of invasiveness is indicated for BDI management. These World Society of Emergency Surgery (WSES) guidelines have been produced following an exhaustive review of the current literature and an international expert panel discussion with the aim of providing evidence-based recommendations to facilitate and standardize the detection and management of BDIs during cholecystectomy. In particular, the 2020 WSES guidelines cover the following key aspects: (1) strategies to minimize the risk of BDI during cholecystectomy; (2) BDI rates in general surgery units and review of surgical practice; (3) how to classify, stage, and report BDI once detected; (4) how to manage an intraoperatively detected BDI; (5) indications for antibiotic treatment; (6) indications for clinical, biochemical, and imaging investigations for suspected BDI; and (7) how to manage a postoperatively detected BDI
Post-hepatectomy liver failure: Should we consider venous outflow?
Introduction: Post-hepatectomy liver failure (PHLF) is one of the most serious complications of liver resection and is associated with high morbidity and mortality rates.
Presentation of case: We report a case of PHLF involving clinical presentation of posthepatectomy-related âsmall-for-sizeâ syndrome (SFSS) secondary to obstructed venous outflow in the liver remnant, following extended right hepatectomy.
Discussion: PHLF is similar to SFSS in liver transplantation (LT) in terms of pathogenesis, clinical presentation and outcomes. Although inflow hypertension is clearly implicated in the pathogenesis of SFSS some authors have suggested that outflow obstruction is a potential pathogenic factor.
Conclusion: The present case support the hypothesis that outflow obstruction could lead symptoms similar to SFSS
Collections postopératoires aprÚs hépatectomie: facteurs de risque et impact à long terme
International audienceIntroduction: Postoperative collection (PC) can occur after liver surgery, but little is known on their impact on short and long-term outcomes. The aim of this study was to analyse factors predicting the occurrence of PC, the need of drainage and their impact on oncologic outcomes.Methods: This single-center, cohort-study included adult patients undergoing liver surgery between 2008 and 2017. The primary objective was to determine variables associated with PC occurrence defined by fluid collection on postoperative day-7 CT scan. Secondary objectives were factors predicting drainage requirement, and predictors of overall survival.Results: During the study period 395 patients were included: 53.6% of them (n = 210) developed a PC with 12% (n = 49) requiring drainage. Variables associated to the occurrence of PC were body mass index > 35 kg/m2 (OR 8.09, 95%CI (1.50,43.60) P = 0.015) and extension of liver surgery (major vs. minor, OR 1.96, 95% CI (1.05,3.64) P 35 kg/m2 have an increased risk to develop a PC: this target population need a systematic imaging in the postoperative period, even if the indication for drainage should be guided by clinical symptoms. Last, the presence of PC requiring treatment has a negative impact on overall survival among patients treated for malignant disease.Introduction: Lâimpact des collections postopĂ©ratoires aprĂšs hĂ©patectomie sur le plan clinique et oncologique est mal connu. Le but de cette Ă©tude Ă©tait dâanalyser les facteurs prĂ©dictifs de dĂ©velopper une collection, de la nĂ©cessitĂ© dâun drainage et de leur impact sur les rĂ©sultats oncologiques.Methodes: Il sâagit dâune Ă©tude de cohorte française monocentrique sur 10 ans (2008â2017) sur des patients adultes ayant bĂ©nĂ©ficiĂ© dâune hĂ©patectomie. Lâobjectif principal Ă©tait de dĂ©terminer les variables associĂ©es Ă la prĂ©sence dâune collection aprĂšs hĂ©patectomie dĂ©finie par une collection liquidienne sur le scanner au 7e jour post-opĂ©ratoire. Les objectifs secondaires Ă©taient les facteurs prĂ©dictifs de drainage et les prĂ©dicteurs de la survie globale.RĂ©sultats: Au cours de la pĂ©riode dâĂ©tude, 395 patients ont Ă©tĂ© inclus: 53,6 % dâentre eux (n = 210) ont dĂ©veloppĂ© une collection, dont 12 % (n = 49) nĂ©cessitant un drainage.Les variables associĂ©es Ă la survenue dâune collection Ă©taient un index de masse corporelle> 35 kg/m2 (OR 8,09, IC Ă 95 % (1,50, 43,60) p = 0,015) et une hĂ©patectomie majeure (OR 1,96, IC Ă 95 % (1,05, 3,64) p 35 kg/m2 ont un risque accru de dĂ©velopper une collection: cette population cible nĂ©cessite une imagerie post-opĂ©ratoire systĂ©matique, mĂȘme si lâindication de drainage doit ĂȘtre guidĂ©e par la symptomatologie clinique. Enfin, la prĂ©sence dâune collection nĂ©cessitant un traitement a un impact nĂ©gatif sur la survie des patients traitĂ©s pour cancer

Developmental anatomy of the liver from computerized three-dimensional reconstructions of four human embryos (from Carnegie stage 14 to 23)
International audienceBACKGROUND & AIM:Some aspects of human embryogenesis and organogenesis remain unclear, especially concerning the development of the liver and its vasculature. The purpose of this study was to investigate, from a descriptive standpoint, the evolutionary morphogenesis of the human liver and its vasculature by computerized three-dimensional reconstructions of human embryos.MATERIAL & METHODS:Serial histological sections of four human embryos at successive stages of development belonging to three prestigious French historical collections were digitized and reconstructed in 3D using software commonly used in medical radiology. Manual segmentation of the hepatic anatomical regions of interest was performed section by section.RESULTS:In this study, human liver organogenesis was examined at Carnegie stages 14, 18, 21 and 23. Using a descriptive and an analytical method, we showed that these stages correspond to the implementation of the large hepatic vascular patterns (the portal system, the hepatic artery and the hepatic venous system) and the biliary system.CONCLUSION:To our knowledge, our work is the first descriptive morphological study using 3D computerized reconstructions from serial histological sections of the embryonic development of the human liver between Carnegie stages 14 and 23
Portal Inflow Modulation by Somatostatin After Major Liver Resection: A Pilot Study
: Major hepatectomy (MH) can lead to an increasing portal vein pressure (PVP) and to lesions of the hepatic parenchyma. Several reports have assessed the deleterious effect of a high posthepatectomy PVP on the postoperative course of MH. Thus, several surgical modalities of portal inflow modulation (PIM) have been described. As for pharmacological modalities, experimental studies showed a potential efficiency of Somatostatin to reduce PVP and flow. To our knowledge, no previous clinical reports of PIM using somatostatin are available. Herein, we report the results of PIM using somatostatin in 10 patients who underwent MH with post-hepatectomy PVP > 20 mmHg. Our results suggest Somatostatin could be considered as an efficient reversible PIM when PVP decrease is above 2.5 mmHg
PDE-5i Management of Erectile Dysfunction After Rectal Surgery: A Systematic Review Focusing on Treatment Efficacy
Erectile dysfunction (ED) is one of the main functional complications of surgical resections of the rectum due to rectal cancers or inflammatory bowel disease (IBD). The present systematic review aimed at revising ED management strategies applied after rectal resections and their efficacy in terms of improvement of the International Index of Erectile Function (IIEF) score. A literature search was conducted on Medline, EMBASE, Scopus, and Cochrane databases by two independent reviewers following the PRISMA guidelines. Randomized and nonrandomized controlled trials (RCTs, NRCTs), case-control studies, and case series evaluating medical or surgical therapies for ED diagnosed after rectal surgery for both benign and malignant pathologies were eligible for inclusion.Out of 1028 articles initially identified, only five met the inclusion criteria: two RCTs comparing oral phosphodiesterase type-5 inhibitor (PDE-5i) versus placebo; one NRCT comparing PDE-5i versus PDE-5i + vacuum erection devices (VEDs) versus control; and two before-after studies on PDE-5i. A total of 253 (82.7%) rectal cancer patients and 53 (17.3%) IBD patients were included. Based on two RCTs, PDE-5i significantly improved IIEF compared to placebo at 3 months (SMD = 1.07; 95% CI [0.65, 1.48]; p < .00001; I2 = 39%). Improved IIEF was also reported with PDE-5i + VED at 12 months. There is a paucity of articles in the literature that specifically assess efficacy of ED treatments after rectal surgery. Many alternative treatment strategies to PDE-5is remain to be investigated. Future studies should implement standardized preoperative, postoperative, and follow-up sexual function assessment in patients undergoing rectal resections
