Biportal endoscopic transforaminal thoracic interbody fusion for the treatment of thoracic myelopathy.

Background: Biportal endoscopic spine surgery independently controls two hands, similar to microscopic surgery, and utilizes a broader working space that is not disturbed by retractors under clear-magnified endoscopic vision. These advantages facilitate successful neural decompression and safe transforaminal interbody fusion, even in patients with thoracic spondylotic myelopathy.

Methods: A wide laminectomy and precise total facetectomy, in conjunction with partial pediculotomy, establish a secure transforaminal space for cage insertion.

Incidence of superficial left hepatic vein and its usability for graft hepatic vein venoplasty in pediatric liver transplantation.

Backgrounds: The anatomy of the left hepatic vein (LHV) is variable; thus, it should be considered for graft hepatic vein (GHV) venoplasty for left lateral section (LLS) and left liver grafts. This study assessed the incidence of superficial LHV (sLHV) branches according to LHV anatomy and its usability for GHV venoplasty in pediatric liver transplantation (LT).

Methods: This study consisted of three parts: (1) anatomical classification of LHV variations and the incidence of sLHV branches; (2) morphometric simulative analysis of GHV reconstruction and (3) clinical application based on LHV anatomy.

Outflow vein venoplasty of left lateral section graft for living donor liver transplantation in infant recipients.

The orifice size of the LHV trunk in LLS grafts is often too small for direct anastomosis. Several methods were developed to enlarge the graft and recipient hepatic vein orifices. This study described our surgical techniques to secure hepatic vein reconstruction in infant recipients and analyzed the patency outcomes.

Portal vein reconstruction using side-to-side unification technique for infant-to-infant deceased donor whole liver transplantation.

Backgrounds/aims: Infant-to-infant whole liver transplantation (I2I-WLT) has been rarely performed in Korea. We analyze clinical sequences of our 7 cases of I2I-WLT and present evolution of surgical techniques to prevent PV stenosis.

Methods: A total of 7 cases of I2I-WLT were performed at our institution during last 13 years, which represented 0.

Neurodevelopmental Prognostic Factors in 73 Neonates with the Birth Head Injury.

Objective: The objective of this study was to reinterpret the neurodevelopmental prognostic factors that are associated with birth head injury by performing a long-term follow-up.

Methods: Seventy-three neonates with head injuries were retrospectively analyzed after a duration of 10.0±7.

Anomalous hepatic vein anatomy of left lateral section grafts and customized unification venoplasty for pediatric living donor liver transplantation.

In liver transplantation, a left lateral section (LLS) graft may have an unusual variant left hepatic vein (LHV) anatomy. This study was designed to analyze the incidence of unusual LHV variants and to determine technical methods for effective reconstruction in infant recipients weighing approximately 10 kg or less. The study comprised 3 parts: an LHV variation analysis, a simulation-based design for the technical modification of graft LHV venoplasty, and its clinical application.
