The Comparison of Sequestrectomy and Conventional Discectomy for the Treatment of a Lumbar Disc
Herniation: A systematic review
country : Argentina

Abstract(Please copy/paste the abstract send to the congress) : Abstract
Study design. Systematic review
Objective. To compare effects of sequestrectomy versus conventional microdiscectomy for lumbar disc herniation.
Summary of Background data. Open surgery for LDH can be performed by sequestrectomy or conventional
discectomy. Generally, it has been assumed that the former is associated with higher risk of recurrence and less
radicular pain and low back pain after surgery.
Methods. We searched MEDLINE and EMBASE from 1980 to November 2014. We selected randomized controlled
trials (RCTs) and prospective studies that compared conventional discectomy versus sequestrectomy for adult
patients with LDH and evaluated the following primary outcomes: radicular pain or LBP as measured by a visual
analogue scale, neurological deficit of lower extremity. We also evaluated the following secondary outcomes:
complications of surgery, reherniation rate, duration of hospital stay, postoperative analgesic use, and health
related quality of life measures. Two authors independently reviewed citations and articles for inclusion. We
assessed the risk of bias as well as the level of evidence for each study, and we used standard methodological
procedures recommended by Cochrane Collaboration.
Results. We identified 5 studies (746 participants) that met our inclusion criteria comparing sequestrectomy versus
microdiscectomy. Comparison revealed that with low-quality evidence, there is no significant difference for
radicular pain, LBP, functional outcome, complications and hospital stay for two years. In addition, with moderatequality
evidence, there is no significant difference for recurrence rate. Meanwhile, there is very low-quality
evidence that analgesic consumption is lower in sequestrectomy than micro/discectomy.
Conclusion. Both interventions had similar effect on pain after surgery, recurrence rate, functional outcome, and
complications; however sequestrectomy may be superior in terms of post-operative analgesic consumption.

The Congress Reporting Form
How many volunteers were present at the Congress? : 1000
Delegates from which countries presented in the congress? : All over the world: USA, UK, Germany, Japan, China, Brazil.
Were the delegates of any other organizations present in the congress? : Yes
If yes, please write the names of the organizations in the box : NASS- North American Spine Society
What were the responses to your talking points? Were specific questions or concerns raised? : My presentation was e-poster. No specific question was performed. However, the study was a systematic review about comparison between sequestrectomy and discectomy with the level of evidence of 1A. Based on the extensive literature search, we found that there are 5 studies (746 participants) that met our inclusion criteria comparing sequestrectomy versus
microdiscectomy. Comparison revealed that with low-quality evidence, there is no significant difference for
radicular pain, LBP, functional outcome, complications and hospital stay for two years. In addition, with moderatequality
evidence, there is no significant difference for recurrence rate. Meanwhile, there is very low-quality
evidence that analgesic consumption is lower in sequestrectomy than micro/discectomy.
Conclusion. Both interventions had similar effect on pain after surgery, recurrence rate, functional outcome, and
complications; however sequestrectomy may be superior in terms of post-operative analgesic consumption.
If you met staff members, please list their full names & positions. : There was no one from Iran except me. I met most giants of the spine in the world.
Please inform us if there are any follow up actions we need to talk with the members of the congress : There is no follow up actions you need to talk with the members of the congress. However, our study was about an interesting title. You would give our study to the professors and residents of neurosurgery and spine surgery: To compare effects of sequestrectomy versus conventional microdiscectomy for lumbar disc herniation.

Your experiences about the travel processes(Providing ticket, accommodation,...) : Extremely difficult. The flight was from Frankfurt. In Emam Khomeini airport, the member of embassy of Germany informed us that we cannot go because of the lack of TRANSIT VISA from Germany, therefore, I bought another ticket from Qatar airline.
Please give a briefing of your own observations and outcomes of the congress: : Congress was in the highest level and fantastic. Presentation of lecture by cartoon and video by MG Fehlings was the highlight of the congress.
My study was an interesting subject and it was in the continuation of my previous systematic review published in Cochrane.
