Dutch Snapshot Research Group

A national surgical network

Welcome!

Welcome to the website of the Dutch Snapshot Research Group (DSRG): a national surgical network aiming to initiate and coordinate large-scale collaborative research projects using the Snapshot study design in the Netherlands. Our network currently consists of 506 surgeons, surgical residents, PhD students, physician assistants and research nurses employed in 75 out of 76 Dutch hospitals. Since 2016, twenty articles were published by the DSRG.

On this website, more information about the DSRG, its projects, and publications can be found. Instructions on how to submit new research ideas are listed under ‘New research ideas’. READ MORE

New Snapshot study: Rectal cancer 2016-2020

A new snapshot study will start this summer. This will be the second snapshot rectal cancer. Repeating this Snapshot study with a 5 years window, gives us the opportunity to evaluate the changes in time. Changes between 2011 and 2016 were a guideline change in 2014 (alter in indication of radiotherapy), realisation of population screening in 2014, further implementation of minimal invasive and organ-sparing surgery. This study also gives the opportunity to investigate the variation in diagnosis and treatment of enlarged lateral lymph nodes. Reassessment of the MRIs of high-risk tumors will reveal which patients had enlarged lateral lymphondes and reassessment of the radiation fields of patients with enlarged lateral lymph nodes will clarify whether these lymph nodes were irrediated.

Tenth publication Snapshot Rectal cancer

The tenth Snapshot study on Rectal cancer has been recently published by Journal of Surgical Oncology. In this study, the effects of preoperative lymph node understaging on postoperative local recurrence rate were investigated. Understaging of lymph nodes is not uncommon, 15% of the included patients were underestimated. The overall 3-year local recurrence rate was 5%.  However, clincal lymph node understaging had no significant impact on the local recurrence rate or overall survival. 

Many thanks to all collaborators!

Second publication Snapshot Acute left-sided obstructive colon cancer

“The second Snapshot study on acute left-sided obstructive colon cancer has been recently published by the Journal of the National Comprehensive Cancer Network (JNCCN). In this study, national practice regarding the treatment of acute left-sided obstructive colon cancer was evaluated, alongside an evaluation of the implementation and effects of the Dutch and European guidelines of 2014. This study demonstrated a trend towards a decrease in emergency resections and an increase in stent placements after 2014, with an ongoing increase in decompressing stoma construction. Overall, more laparoscopic resections were observed after 2014, with more 2-stage procedures and fewer permanent stomas in the stoma group specifically compared to patients treated before 2014. However, 90-day morbidity and 90-day mortality remained relatively high.

Many thanks to all collaborators!
