Utilisation du laser CO2 dans le traitement endoscopique des diverticules pharyngo-œsophagiens de Zenker : Expérience à propos de 33 cas

Microendoscopic treatment of hypopharyngeal (Zenker's) diverticulum was performed in 31 patients during the period 1990-1995. The CO2 laser combined with the operating microscope has been used. 33 endoscopic procedures were performed (2 procedures were needed for 2 patients). The average age of the patients was 70.3 years (46-86 years). The average length of the general anesthesia was 48 minutes; the average length of the endoscopic procedure was 20 minutes. No major complication occurred for 32/33 cases (97%). Mediastinitis occurred for 1 case (3%) and was successfully treated by surgical and IV antibiotherapy. The average duration of hospitalization was 5 days (3-5 days) (patient with mediastinitis excluded): the average follow-up was 19 months (1-62 months). 28/31 patients (90.3%) were highly or fairly satisfied. Considering the external approach microendoscopic CO2 laser diverticulotomy offers comparable functional results. Moreover, this procedure is quick, requires a shorter hospitalization stay and is followed by a very low percentage of complications. Additionally, no visible scar is noted. Optimal management of Zenker's diverticulum remains controversial. However, we advocate that microendoscopic CO2 laser diverticulotomy should be considered as a first-line treatment option for patients with hypopharyngeal diverticulum

Nuclear physics midterm plan at Legnaro National Laboratories (LNL)

International audienceThe next years will see the completion of the radioactive ion beam facility SPES (Selective Production of Exotic Species) and the upgrade of the accelerators complex at Istituto Nazionale di Fisica Nucleare – Legnaro National Laboratories (LNL) opening up new possibilities in the fields of nuclear structure, nuclear dynamics, nuclear astrophysics, and applications. The nuclear physics community has organised a workshop to discuss the new physics opportunities that will be possible in the near future by employing state-of-the-art detection systems. A detailed discussion of the outcome from the workshop is presented in this report
