Peer-reviewed research behind HemoChat

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.

Postoperative urinary retention after oblique lumbar interbody fusion under the systematic management protocol

Lim J, Lim J, Khan A, Lee C-H, Kim J-H, Choi S, Kim T-S, Choi Y, Chung CK, Yoon ST, Kim K-T, Kim CH

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.

Spinal Schwannoma Classification Based on the Presumed Origin With Preoperative Magnetic Resonance Images

Kim T-S, Kuh JH, Kim J, Yuh WT, Han J, Lee C-H, Kim CH, Chung CK

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.

Machine-learning-based models for the optimization of post-cervical spinal laminoplasty outpatient follow-up schedules

Seo Y, Jeong S, Lee S, Kim T-S, Kim J-H, Chung CK, Lee C-H, Rhee JM, Kong HJ, Kim CH

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.

The iterative implementation of a comprehensive enhanced recovery after surgery protocol in all spinal surgery in Korea

Yuh WT, Kim J-H, Han J, Kim T-S, Won Y-I, Choi Y, Noh HJ, Lee C-H, Kim CH, Chung CK

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.

Is laminectomy necessary for C1-C2 epidural schwannomas?

Kim T-S, Yuh WT, Han J, Kim J-H, Lee C-H, Kim CH, Chung CK

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.

Surgical treatment of spondylolisthesis by oblique lumbar interbody fusion and transpedicular screw fixation

Han J, Ha CM, Yuh WT, Ko Y-S, Kim J-H, Kim T-S, Lee C-H, Lee S

Retrospective series on treating lumbar spondylolisthesis with oblique lumbar interbody fusion combined with transpedicular screw fixation — reports clinical and radiographic outcomes and compares them with other established fusion approaches.
