Virtual Educational Channel

OESO and the OESO-SEMPIRE Platform of Excellence in Esophagology

continue to be a trail blazer

in all fields of Esophagology.


A new model of Education has come forward

with the OESO-SEMPIRE Virtual Educational Channel.


Indeed, going beyond the traditional series of presentations one after the other,

the clinical case of a patient becomes the focal point of interest: it becomes
the starting point of a two hour intense educational interaction between top experts,

punctuated by comments and questions by a worldwide floor.


10th meeting:

Hosted by Prof. L. Bonavina, Milan

Wednesday, May 26, 2021


Details and time will be announced soon

Presentation of the case:

  • Stéphane Bonnet (IMM)

A 68-year-old patient, with intermittent dysphagia to liquids and solids,

painful thoracic spasms and intermittent vomiting. Loss of weight around 15 kg.


Diagnosis process:

  • CT scan: 5cm long circumferential thickening of the mid thoracic esophagus.
  • Endoscopy: pseudo tracheal aspect of the esophagus («trachealization») with multiple rings and no peristalsis.
  • Biopsies: normal without eosinophilic esophagitis.
  • PET/CT: suspicious 12cm long esophageal fixation (SUV max 15,6).
  • Echo-endoscopy: thickening and fusion of wall layers, 36 to 39cm from dental arch.
  • High-resolution manometry: impaired relaxation of LES, pan esophageal pressurization pattern.


Therapeutic process:

  • After multidisciplinary discussions,
    a first series of Botox injections was performed with slight beneficial effect on pain.
  • ​Considering the atypical outcome,
    a new echo-endoscopy was performed showing a corkscrew aspect of the esophagus and a pseudo diverticulization between 30 to 42cm from dental arch.
  •  Following a new board discussion,
    a myotomy, achieved by thoracoscopic approach in prone position, was performed.


Follow-up: Six months later, the patient eats normally, with no pain, and is gaining weight.


Discussion points: the difficult problems of diagnostic and therapeutic approach regarding atypical dysphagia.

  • Pre-treatment imaging and endoscopic workup and its interpretation,
  • Choice of management (endoscopic or surgical approach),
  • Long-term results.


​Discussion led by Brice Gayet and Stéphane Bonnet, IMM, Paris

with a top level panel currently being assembled.


Panel for discussion:

  • Robert Bechara, Kingston, Canada
  • Stefan Mönig, Geneva, Switzerland
  • Marcelo Vela, Mayo Clinic, Scottsdale, AZ, USA
  • Bruno Zilberstein, Sao Paulo, Brazil


Registration is free, but mandatory.

The next 10th Clinical case coming up for discussion on May 2021 will be proposed by
Prof. Luigi Bonavina from Milan.


Details and time will be announced on the OESO website and in the next Newsletter.






In the framework of its cooperation with the New York Academy of Sciences, OESO is pleased to announce to the international scientific community the publication (Wiley Publ.) of the 15th and 16th volumes of its Encyclopedia of Esophagology.


These two books, which follow the 15th OESO World Congress in Beijing, contain 39 Review Articles in two consecutive special issues of the Annals of the New York Academy of Sciences.


These 39 papers, like the congress they follow, cover topics related to the various disciplines represented in OESO, and each of them is the result of the work of teams of international specialists of the highest level in their fields.



These 2 volumes are available on the 2 links provided here below:


multi-disciplinary, updated information of the highest interest.



These two issues of Annals of the New York Academy of Sciences (Volumes 1481 and 1482) further the mission of the OESO (World Organization for Specialized Studies on Diseases of the Esophagus): dissemination of knowledge and the sharing of information in the field of the foregut.


The work of the OESO is in line with the UNESCO Constitution and directed toward state-of-the art clinical evaluations of patients from worldwide teams of experts in the nineteen disciplines represented in its scientific committees.


Since its founding, the OESO has fostered a close relationship with Annals of the New York Academy of Sciences that has resulted in several special issues published over the past decade.

The newly created OESO-Stanford SEMPIRE Platform of Excellence in Esophagology, in cooperation with Stanford Medicine, plans to initiate a multidisciplinary educational program that includes discussions of clinical cases and access to second opinion.
