Prospective Evaluation of Ultrasonic Surgical Dissectors in Hepatic Resection: A Cooperative Multicenter Study

Blood loss is the major cause of postoperative mortality and morbidity associated with hepatic resection. A prospective multicenter study was conducted to determine if ultrasonic dissectors (USD) were useful in hepatic resection and could reduce this hemorrhagic risk. Forty-seven hepatic resections were performed in 42 consecutive patients during a two month period in 11 public, surgical centers. Twenty-one patients had primary or secondary malignancies, six had benign tumors, two had biliary cysts, one had cholangiocarcinoma, one had Caroli’s disease, and 11 had hydatid cysts of the liver. Two different USD devices were evaluated (CUSA System-Lasersonics and NIIC-DX 101 T). The hepatic resections tested included a wide range of procedures. Each surgeon had the possibility of choosing between the USD and his own usual technique for each operative step and according to local conditions. The average volume of blood infused, irrespective of the underlying pathology or the procedure performed, was 1.0 L (range 0-4.8 L). Fourteen patients required no transfusions. No operative or immediate postoperative deaths were recorded. Five major complications, all unrelated to the use of the USD, developed in three patients. Access to intra and extraparenchymal arterial and venous tributaries and particularly the control of the hepatic veins were facilitated by USD. While transection of hepatic parenchyma was neither easier nor faster than with conventional techniques, it was found to be less hemorrhagic. Overall appraisal was expressed on an analog scale; the USD was found to be helpful or very helpful in 75 percent of all resections. With regard to the pathology being treated, total or partial excision of hydatid cysts was greatly enhanced by the use of the USD while this benefit was not found for wedge resections of other hepatic lesions. With regard to user friendliness and maintenance, the NIIC-DX 101 T device was preferred. We conclude that the USD facilitates formal hepatic resections. Converging opinions emerging from various surgical centers reinforce this conclusion

Prostate cancer outcomes in France: treatments, adverse effects and two-year mortality

BACKGROUND: This very large population-based study investigated outcomes after a diagnosis of prostate cancer (PCa) in terms of mortality rates, treatments and adverse effects. METHODS: Among the 11 million men aged 40 years and over covered by the general national health insurance scheme, those with newly managed PCa in 2009 were followed for two years based on data from the national health insurance information system (SNIIRAM). Patients were identified using hospitalisation diagnoses and specific refunds related to PCa and PCa treatments. Adverse effects of PCa treatments were identified by using hospital diagnoses, specific procedures and drug refunds. RESULTS: The age-standardised two-year all-cause mortality rate among the 43,460 men included in the study was 8.4%, twice that of all men aged 40 years and over. Among the 36,734 two-year survivors, 38% had undergone prostatectomy, 36% had been treated by hormone therapy, 29% by radiotherapy, 3% by brachytherapy and 20% were not treated. The frequency of treatment-related adverse effects varied according to age and type of treatment. Among men between 50 and 69 years of age treated by prostatectomy alone, 61% were treated for erectile dysfunction and 24% were treated for urinary disorders. The frequency of treatment for these disorders decreased during the second year compared to the first year (erectile dysfunction: 41% vs 53%, urinary disorders: 9% vs 20%). The frequencies of these treatments among men treated by external beam radiotherapy alone were 7% and 14%, respectively. Among men between 50 and 69 years with treated PCa, 46% received treatments for erectile dysfunction and 22% for urinary disorders. For controls without PCa but treated surgically for benign prostatic hyperplasia, these frequencies were 1.5% and 6.0%, respectively. CONCLUSIONS: We report high survival rates two years after a diagnosis of PCa, but a high frequency of PCa treatment-related adverse effects. These frequencies remain underestimated, as they are based on treatments for erectile dysfunction and urinary disorders and do not reflect all functional outcomes. These results should help urologists and general practitioners to inform their patients about outcomes at the time of screening and diagnosis, and especially about potential treatment-related adverse effects

MYH7 p.(Arg1712Gln) is pathogenic founder variant causing hypertrophic cardiomyopathy with overall relatively delayed onset

Introduction: The MYH7 c.5135G &gt; A p.(Arg1712Gln) variant has been identified in several patients worldwide and is classified as pathogenic in the ClinVar database. We aimed to delineate its associated phenotype and evaluate a potential founder effect.Methods: We retrospectively collected clinical and genetic data of 22 probands and 74 family members from an international cohort.Results: In total, 53 individuals carried the MYH7 p.(Arg1712Gln) variant, of whom 38 (72%) were diagnosed with hypertrophic cardiomyopathy (HCM). Mean age at HCM diagnosis was 48.8 years (standard deviation: 18.1; range: 8–74). The clinical presentation ranged from asymptomatic HCM to arrhythmias (atrial fibrillation and malignant ventricular arrhythmias). Aborted sudden cardiac death (SCD) leading to the diagnosis of HCM occurred in one proband at the age of 68 years, and a family history of SCD was reported by 39% (5/13) probands. Neither heart failure deaths nor heart transplants were reported. Women had a generally later-onset disease, with 14% of female carriers diagnosed with HCM at age 50 years compared with 54% of male carriers. In both sexes, the disease was fully penetrant by age 75 years. Haplotypes were reconstructed for 35 patients and showed a founder effect in a subset of patients.Conclusion: MYH7 p.(Arg1712Gln) is a pathogenic founder variant with a consistent HCM phenotype that may present with delayed penetrance. This suggested that clinical follow-up should be pursued after the seventh decade in healthy carriers and that longer intervals between screening may be justified in healthy women &lt; 30 years.</p

Current challenges in providing bariatric surgery in France

International audienceBariatric surgery is a well-accepted procedure for severe and massive obesity management. We aimed to determine trends, geographical variations, and factors influencing bariatric surgery and the choice of procedure in France in a large observational study.The Health Insurance Fund for Salaried Workers (Caisse National Assurance Maladie Travailleurs Salariés) covers about 86% of the French population. The Système National d'Information Inter-régimes de l'Assurance Maladie database contains individualized and anonymized patient data on all reimbursements for healthcare expenditure. All types of primary bariatric procedures (Roux-en-Y gastric bypass [RYGB] or omega loop, adjustable gastric banding [AGB], or longitudinal sleeve gastrectomy [LSG]) performed during 2011 to 2013 were systematically recorded. Surgical techniques performed by region of residence and age-range relative risks with 95% confidence intervals of undergoing LSG or RYGB versus AGB were computed.In 2013, LSG was performed more frequently than RYGB and AGB (57% vs 31% and 13%, respectively). A total of 41,648 patients underwent a bariatric procedure; they were predominantly female (82%) with a mean (±standard deviation) age of 40 (±12) years and a body mass index ≥40 kg/m for 68% of them. A total of 114 procedures were performed in patients younger than 18 years and 2381 procedures were performed in patients aged 60 years and older. Beneficiaries of the French universal health insurance coverage for low-income patients were more likely to undergo surgery than the general population. Large nationwide variations were observed in the type choice of bariatric surgical procedures. Significant positive predictors for undergoing RYGB compared to those for undergoing AGB were as follows: referral to a center performing a large number of surgeries or to a public hospital, older age, female gender, body mass index ≥50 kg/m, and treatment for obstructive sleep apnea syndrome, diabetes, or depression. Universal health insurance coverage for low-income patients was inversely correlated with the probability of RYGB.Differences in access to surgery have been observed in terms of the patient's profile, geographical variations, and predictors of types of procedures. Several challenges must be met when organizing the medical care of this growing number of patients, when delivering surgery through qualified centers while assuring the quality of long-term follow-up for all patients

Optimal trocar placement for ergonomic intracorporeal sewing and knotting in laparoscopic hiatal surgery

BACKGROUND: Trocar placement presently is mostly empiric. Our goal was to define simple distances from bony landmarks to locate the optimal ergonomic placement of manipulation trocars for access to the lower esophagus and hiatal orifice, for suture placement, and knotting of the gastric fundus and crura. Hypothesizing that the ideal ergonomic principles of a manipulation angle of 60 degrees, an elevation angle (alpha(e)) of 30 degrees to 60 degrees, and an intracorporeal/extracorporeal length ratio (TIE) of working instruments close to 1:1 are interrelated by simple trigonometric functions, the variations of each of these parameters were calculated in a dependent manner for 2 standard lengths of needle holders: 48.5 cm and 58.5 cm. RESULTS: Trocar placement can be calculated easily according to simple formulas dependent on the alpha(e), the distance from the sternoxiphoid junction to the median of the intertrocar span (d) and the vertical distance from the stenoxiphoid junction to the average distance between the apex of the hiatal orifice and the anterior aspect of the esophagus (XH’): when the alpha(e) is 30 degrees: d is XH’ root 2 and when alpha(e) is 45 degrees, d is XH’/root 2. Likewise, when alpha(e) is 30 degrees the intertrocar span (LR) is 2XH’, half on either side of the optical axis (d), and when alpha(e) is 45 degrees, LR is XH’ root 2, XH’/root 2 on either side of the optical axis. The most ergonomic solution is to work with an alpha(e) of 40 degrees to 45 degrees by placing the 2 working (manipulation) trocars, between 10 and 14 cm caudad from the sternoxiphoid junction, between 10 and 12 cm on either side of the longitudinal axis corresponding to the optic-target axis. The shorter needle holder works best in this configuration because the I/E ratio will be between .8 and 1. If, however, the surgeon wants to work with an alpha(e) closer to 30 degrees, then the longer needle holder should be used, and the trocars should be placed between 20 and 21 cm from the sternoxiphoid junction, 14.5 to 15 cm on either side of the optical axis. The I/E ratio will vary between 1 and 1.1. When a 1/1 I/E ratio was prioritized, the alpha(e) would be 40 degrees and 32 degrees, for the shorter and longer instruments, respectively. The deeper crural closure requires increasing the alpha(e) by 2 degrees and 3 degrees, respectively. Hyperlordosis, as obtained by placing a cushion under the patient’s back, shortens the distances, allowing placement of the trocars closer to the sternoxiphoid junction. CONCLUSIONS: Based on ergonomic principles (manipulation angle, 60 degrees; alpha(e), 40 degrees-45 degrees; and an I/E ratio of working instruments, close to 1:1), simple trigonometric considerations allow easy calculation of the ideal placement of trocars corresponding to working instruments in hiatal surgery necessary for ergonomic dissection, suturing, and intracorporeal knotting. Ideal trocar placement is dependent only on the vertical depth of the target organ. (C) 2010 Elsevier Inc. All rights reserved

Results of the FUSE Evaluation Project in France

International audienceBackgroundThe Federation of Visceral and Digestive Surgery (FCVD) is in charge in France of the continuing medical education of digestive surgeons. Since 2016 and in collaboration with SAGES, it has offered the Fundamental Use of Surgical Energy (FUSE) program as part of the continuing education for surgeons including eLearning and hands-on workshops.MethodsThe aim of this study was to evaluate the impact of the FUSE program on the participants by participating in a knowledge test and completing a survey.Results485 participants fully completed the knowledge test of 18 questions. Post-test assessment showed an increase in the mean score with respect to pre-test assessment, and the surgeons who have participated to the hands-on workshops had a better score. 304 participants filled the survey of 6 questions. The majority were satisfied by the FUSE program and felt that the objectives were achieved.ConclusionsThe FUSE program developed by SAGES and adopted by the FCVD in France was very much appreciated by the participants and achieved its educational objectives. Our goal is to spread it as widely as possible to all members of the operating room team
