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,
- on the APDW website to attend the congress and participate in the discussion.
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.
Details on program and time will be announced on the OESO website and in the next Newsletter.

High grade dysplasia
A 65 year old, white male patient.
- Heartburn and regurgitations for 20 years
- No dysphagia, no respiratory symptoms
- Regular use of PPI – 60 m Dexalanzoprazol for the last 3 years
- No weight loss. (BMI = 25 Kg/m2)
2 cm hiatal hernia
C4M6 Barrett’s esophagus (Prague classification)
Nodular area with microvascular patterns alterations
- Biopsies: High grade dysplasia in Barrett’s epithelium
- CT scan and Echo-endoscopy: no remarkable findings
- ESD / resection of the lesion and 60% of the columnar epithelium.
- Histology: moderately differentiated adenocarcinoma (T1a)
Invasion till the mucosa
Lateral and deep margins free of adenocarcinoma
- Follow-up endoscopy 3 months after ESD:
3 cm hiatal hérnia (Type I)
Ulcer in distal esophagus on the previous site of ESD
Recurrent columnar epithelium in distal esophagus
- Biopsies: Barrett’s epithelium with intestinal metaplasia without dysplasia
Surveillance endoscopy planned for 2 months, with biopsies/Seattle protocol,
and RFA ablation of the Barrett epithelium.
Due to COVID 19 pandemic, the patient returned to our department
only after 14 months, complaining of mild dysphagia.
Elevated lesion on the anterior wall of distal esophagus. Biopsies (A)
Ulcer-infiltrative lesion at the right posterolateral wall of the distal esophagus. Biopsies (B)
3 cm hiatal hernia (Type I).
A: Invasive, moderately differentiated adenocarcinoma at the squamous-columnar junction
B: Poorly differentiated carcinoma at the squamous-columnar junction with intestinal metaplasia and high grade dysplasia in the adjacent columnar mucosa
- PET-CT scan: 2-3cm lesion at the GEJ (SUV max 11,2).
No suspicious lymph nodal invasion.
- Subtotal esophagectomy with lymphadenectomy and gastric pull-up.
- Histology: poorly differentiated adenocarcinoma at the squamo-columnar junction with intestinal metaplasia and high grade dysplasia in the adjacent columnar mucosa (pT3pN2M0).
- Postoperative chemotherapy
- 6 months after surgery, disease-free patient without any complication.
