Publications by the founder and his research group at Seoul National University Hospital.
HemoChat is built by Dr. Tae-Shin Kim, a neurosurgeon in the Department of Neurosurgery at Seoul National University Hospital. His peer-reviewed work focuses on spinal tumors (schwannoma classification, C1–C2 surgical decision-making) and on perioperative optimization of spine surgery (ERAS protocols, post-operative urinary retention, follow-up scheduling). The list below is drawn directly from PubMed — 2 first-author papers and 4 co-authored papers.
Summaries on this page are original paraphrases written by HemoChat; we do not host journal-owned abstracts or full text. Use the DOI link on each card for the journal version of record.

Evaluates incidence and risk factors for post-operative urinary retention (POUR) after oblique lumbar interbody fusion, and assesses the impact of a standardized bladder-management protocol (scan thresholds, intermittent catheterization, pharmacotherapy) on patient outcomes.

Proposes a nine-type classification system for spinal schwannomas based on the presumed nerve of origin inferred from preoperative MR imaging. Validated on 482 prospectively collected cases: the new system eliminates the 'unclassified' category present in older schemes (Eden, Sun-Pamir, Sridhar) and achieves an 88.0% gross-total-removal rate when used to plan the surgical approach.

Trains ML models to predict which post-cervical-laminoplasty patients need near-term outpatient review vs. can safely be pushed to a longer follow-up interval. Intended to reduce unnecessary visits for low-risk patients while preserving early detection for those at risk of complications.

Reports the staged 2003–2011 development and 2012 full roll-out of a comprehensive ERAS protocol covering every spine surgical procedure at a tertiary Korean centre. Interrupted-time-series analysis over 7,143 procedures shows a 22% reduction in length-of-stay and medical cost — more pronounced for primary spine tumors — with unchanged 30-day readmission, re-operation, and surgical-site-infection rates.

Single-centre retrospective review of 53 C1-C2 epidural schwannoma cases comparing tumor removal with vs. without laminectomy. Finds that the intradural portion's diameter — not the transverse diameter, craniocaudal length, or volume — is the single factor that dictates whether laminectomy is needed: tumors with a smaller intradural part can be removed without laminectomy, cutting operative time and without compromising gross-total-removal or complication rates.
