Virtual Educational Channel



  • Virtual Global interactive Staff Meetings around a clinical case


The constraints of the worldwide Covid-19 pandemic require OESO to adapt its educational structure.

A new initiative responds to this need: the OESO-SEMPIRE VIRTUAL EDUCATIONAL CHANNEL.


It is built on the basis, already operational, of the OESO-SEMPIRE Platform

coordinating the educational activities of a network of Pilot Centers of Excellence in Esophagology worldwide.


Like many of the previous ones, this approach is original, multi-disciplinary, and, from the outset, global.

Its implementation is made possible by use of the virtual techniques of communication available today.


Each time, one of the Pilot centers will propose a challenging clinical case open for interactive discussion, followed by the commentary of an invited expert.

The topic and time will be announced well in advance on the OESO website, with specification of the time to allow connection at a comfortable hour of the day.



Join us,

for an innovative series of international "Staff meetings" with experts from the five parts of the world.


The OESO-SEMPIRE virtual channel will welcome, in addition to the Pilot Centers of the network
able to connect, the contribution of

  • all the members of OESO,
  • other renowned specialists bringing their specific knowledge into the network, whatever their discipline,
  • and, more widely, members of the international scientific community.



  • Setting up a meeting


  • Transmitted from one of the Pilot Centers of the OESO-SEMPIRE Platform.
  • Intended for Pilot Centers in another part of the world, taking into account the time differences.
  • Chaired by the Scientific Director of the Center with a member of the junior faculty.
  • Short duration: 1-2 hours.



  • Presentation of a challenging case in esophagology, preferably involving several disciplines,
    – Exchange of views between the presenters,
    – Discussion with people connected in another part of the world with their audience
       (prior announcements made by the Centers to encourage attendance).
  • Invited commentary given by an internationally recognized expert who can also contribute his/her experience to the panel discussion.
    These experts don't have to belong to the OESO-SEMPIRE network.



  • Zoom type technology,
  • with announcement well in advance requiring prior signing up of potential participants.
  • Courses and discussions recorded and available on the OESO website.


  • Time zones                                                                                          > Chart download pdf


Each Pilot Center to choose a preferable time (7-9 am or 5-7 pm) for its program

and know the corresponding time for other Centers wishing to attend the meeting.

  • 3rd meeting: Saturday, October 3, 2020


Hosted by Russel White and Michael Mwachiro

From Tenwek Hospital (Bomet, Kenya)


Multidisciplinary Panel for discussion:

Matthew Read (Melbourne) – Kumwinder Dua (Milwaukee) 

  • Time: 7-9 am EAT (East African Time, GMT+3)
  • Zoom technology applied
  • Zones in a comfortable time to connect to the meeting:


Gist of the Case:

An unusual case of a 6 year old female involving a foreign body lodged in the esophagus for an extended period of time. The case required a multidisciplinary approach between surgeons and endoscopists to provide appropriate initial care for the patient, and for the complications which arose.


The patient complained of a persistent cough of at least three months duration. She had a chest radiograph performed which revealed the presence of a foreign body in the oesophagus at the level of the tracheal carina. Neither she nor her mother recalled the incident of ingesting the foreign body. The child was able to tolerate a normal diet without difficulty. She did not appear to be in any significant distress, but did have a persistent cough.


Upper GI endoscopy revealed a metallic foreign body, firmly wedged in the mid-esophagus. There appeared also to be a trachea-esophageal fistula present in the anterior surface of the esophagus.


Discussion points, with a panel of experts:

  • What would you do with this patient?
  • What would be your therapeutic strategy?
  • How would you proceed surgically?

Gist of the Case:

A challenging case of achalasia in the context of hypersensitivity and other comorbidities, with dilemmas in treatment and complications thereafter.

One of the most challenging cases of achalasia management that we have seen at Stanford and sure to stimulate conversation.

 • Physiology of achalasia

 • How to choose the initial line of therapy

 • Complications after surgical intervention

 • Treatment of reflux after achalasia therapy

 • When to consider esophagectomy0
