For submission of abstracts to JDDW, the transitional measures (allowing submission 1. In the case of the review by ethics committee is still under application 2. From facilities without ethics committee, if taking opt-out measures under the approval of the head of the facility) have been abolished.
Presentations that are required the ethical review must receive approval by the ethics committee in affiliated university hospitals, academic societies or medical association before your abstract submission.
A checklist regarding the ethics review is provided on the submission page. The checklist enables applicants to recognize the ethics policies for which compliance is obligatory. In the case that the abstract reviewers object to the declaration, your abstract will be verified by each society’s program committee. Please note that your abstract would be rejected if deemed inappropriate.
Please confirm here to find the category to which your abstract applies.

For the JDDW the following call for abstracts aims to make a definite distinction between the events and to increase the value of the program through the symposiums, panel discussion, and workshops.
JDDW has established the awards for outstanding abstracts and presentations.
Screening will be conducted by the JDDW steering committee.
The awards will be given for the first author or the presenters only.
When the first author or presenter is changed, the abstract will not be eligible for the awards.
For more details of each award, please refer to the following information.
Acceptance or rejection will be decided through consultation with the respective Chairperson of each session.

JDDW 2023 is subject to venue restrictions, limitations on time, and other constraints. For this reason, the following rules have been established in regards to the handling of case reports in digital poster abstracts for JDDW 2023 (these rules do not apply to the abstracts for the Japanese Society of Gastroenterological Surgery):
Please register via “Theme session abstract” on the registration screen. Please select your desired theme. You may register up to 3 presenters.
Persons making dual submission (submit first as a theme session abstract, but in the event that it is not accepted, it may be screened for digital poster session), please register using “Dual submission.” You will need to submit two abstracts: one for digital poster session and another for theme session. Two registration numbers will be issued: one for digital poster session and another for theme session. Please be sure you do not mix up these two numbers.
A total of three persons, including the lead presenter, may be registered for “Theme session abstract,” and up to 20 persons for “Digital poster session abstract.”
The word count limit for abstracts (combined total for title, body, speaker name and name of affiliated institution) is a maximum of 250 words. If using a chart/table, the maximum is 167 words.
If the maximum word count is exceeded, you will not be able to register it.
In the column for the body text, please enter only the main text of the abstract, and do not include the title, name of affiliated institution, name of author or index terms.
You can register a single file of figure/table. You may use whatever software you wish to create the figure/table. However, please ensure that the file size is small and uses as few colors as possible.
