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

Robotic esophagectomy for locally advanced distal esophageal cancer


A 52 year old man with a locally advanced adenocarcinoma of the distal esophagus.


  • Two-month abdominal pain associated with symptoms of gastro-esophageal reflux. Absence of dysphagia.
  • Upper gastrointestinal endoscopy: exophytic and ulcerated tumor, not stenosing, extended from 27 cm to 35 cm from upper incisors, occupying 2/3 of the circumference.
  • Biopsy: poorly differentiated adenocarcinoma.
  • Ultrasound-endoscopy staging: uT3 uN+ (peritumor lymph nodes).
  • Thoraco-abdominal computed tomography (CT SCAN): distal esophagus tumor, with peritumor lymph nodes, no distant metastasis.
  • PET-CT: positive FDG up-take, distal esophageal carcinoma with no evidence of distant metastasis.
  • Tumor markers: CA 19-9 7.2 U/ml; CEA 2.0 U/ml
  • Clinical staging: uT3uN+cM0


Discussion at Tumor Board, with indication of neoadjuvant therapy.

  • CROSS regimen from 18.01.2021 to 17.02.2021 (36/41.4 Gy).
    Radiotherapy was not well tolerated, due to progressive radio-induced esophagitis. The patient therefore required home parenteral nutrition.



  • Upper gastrointestinal endoscopy: not stenosing exophytic tumor, in partial regression.
    Thoraco-abdominal computed tomography (CT SCAN):
    regression of the esophageal parietal thickness.
    No evidence of distant metastasis.


Surgical treatment decided at Tumor Board meeting:

  • Robotic assisted Ivor-Lewis esophagectomy with 2-field lymphadenectomy
  • Uneventful post-operative period. Patient discharged in 8 days.


Final pathology:

  • ypT0, ypN0 (0/33), L0, V0, Pn0, R0 (complete histopathological response).
  • Clinical, radiologic and endoscopic follow up with no evidence of recurrence or distant metastasis so far.


Presentation of the case:

  • Prof. Peter Grimminger (Mainz)


Discussion points:

  • The role of totally robotic assisted surgery in the treatment of locally advanced tumors of distal esophagus,
  • Tailored treatment of advanced esophageal carcinoma.


Panel of experts for discussion:

  • Philip Chiu (Hong Kong)
  • Klaus Emmanuel (Salzburg)
  • Caterina Froiio (Milan)
  • Magnus Nilsson (Stockholm)
  • Richard Van Hillegersberg (Utrecht)


Registration is free, but mandatory.

At the time of the tremendous Asian Pacific Digestive Week (APDW)

(Kuala Lumpur, August 19-22),


OESO has been invited to organize a particular session which, in the scientific program of this big event, would take place respecting the original, specific OESO format of sharp questions followed by replies in no more than 5 minutes each.


The Congress organizers have made it possible for OESO to have a virtual booth in the virtual exhibit of the Conference.


You will find below the brochure OESO has drawn up for this occasion: it offers a very brief synthesis of the history of our Organization and, especially, its prospects for the years to come.


We hope that you will connect,


  • on the following brochure which comprises the program of this OESO session,

OESO brochure

  • on the APDW website to attend the congress and participate in the discussion.

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.
