A 70-year-old female presented with bilateral numbness in her upper limbs. She was diagnosed with cervical spondylotic myelopathy and underwent cervical laminoplasty. However, there was no significant improvement in sensory disturbance, and at 6 months after surgery, she developed subacute motor and gait disturbance in four extremities.

Preventing an 8-mm Port Site Hernia in Robot-Assisted Laparoscopic Surgery: Insights From Two Rare Cases and Future Preventive Measures.

Port-site incisional hernia (PIH) is an uncommon complication that can arise subsequent to a laparoscopic procedure, potentially leading to severe adverse effects such as intestinal obstruction. We currently present two cases of incarcerated hernia that occurred at an 8-mm trocar site after robot-assisted laparoscopic surgery (RALS). While occurrences of an 8-mm port-site incisional hernia are infrequent, it is imperative to note that most PIH cases are due to inadequate fascial closure of the port site.

Surgical Strategy in Bouveret's Syndrome: Report of a Case With One-Stage Surgery.

Bouveret's syndrome is a rare condition caused by a gallstone that impacts the duodenum via a cholecystoduodenal fistula and obstructs the gastric outlet. Despite its high mortality rate, the treatment strategy for Bouveret's syndrome is debatable and frequently challenging. The main issue is whether cholecystectomy and fistula repair following stone extraction should be performed concurrently with one-stage surgery.

Favorable prognosis in posterior circulation ischemic stroke: Insights from a nationwide stroke databank.

Introduction: Clinical trials have historically underrepresented patients with posterior circulation ischemic stroke (PCIS). This study aimed to comprehensively assess the clinical characteristics and outcomes of PCIS patients compared to those with anterior circulation ischemic stroke (ACIS).

Methods: A retrospective analysis was conducted using data from the Japan Stroke Data Bank, encompassing 20 years across 130 stroke centers.

Cardiac Damage in Degenerative Mitral Regurgitation Treated With Transcatheter Mitral Edge-to-Edge Repair.

Background: The extent of cardiac damage and its association with clinical outcomes in patients undergoing transcatheter edge-to-edge repair (TEER) for degenerative mitral regurgitation remains unclear. This study was aimed to investigate cardiac damage in patients with degenerative mitral regurgitation treated with TEER and its association with outcomes.

Methods: We analyzed patients with degenerative mitral regurgitation treated with TEER in the Optimized Catheter Valvular Intervention-Mitral registry, which is a prospective, multicenter observational data collection in Japan.

Long-term prognostic value of the HFPEF score in patients undergoing transcatheter aortic valve implantation.

Aims: A considerable proportion of candidates for transcatheter aortic valve implantation (TAVI) have underlying heart failure (HF) with preserved ejection fraction (HFpEF), which can be challenging for diagnosis because significant valvular heart disease should be excluded before diagnosing HFpEF. This study investigated the long-term prognostic value of the pre-procedural HFPEF score in patients with preserved ejection fraction (EF) undergoing TAVI.

Methods And Results: Patients who underwent TAVI between October 2013 and May 2017 were enrolled from the Optimized CathEter vAlvular iNtervention-Transcatheter Aortic Valve Implantation Japanese multicentre registry.

Polymer-based drug-eluting stent treatment extends the time to reintervention for patients with symptomatic femoropopliteal artery disease: clinical evidence and potential economic value.

Use long-term follow-up data from the IMPERIAL study to determine whether drug-eluting polymer-based nitinol stent treatment can delay the time to repeat intervention for femoropopliteal artery disease and how such a delay may result in cost savings in a value-based episode of care. The IMPERIAL randomized controlled trial was an international study of a paclitaxel-eluting polymer-coated stent (Eluvia, Boston Scientific, MA, USA) versus a polymer-free paclitaxel-coated stent (Zilver PTX, Cook Corporation, IN, USA) for treating lesions of the femoropopliteal arterial segment. Study patients (n = 465) had symptomatic lower limb ischemia.

Outcomes of left bundle branch area pacing compared to His bundle pacing and right ventricular apical pacing in Japanese patients with bradycardia.

Background: His bundle pacing (HBP) and left bundle branch area pacing (LBBAP) emerge as better alternatives to right ventricular apical pacing (RVAP) in patients with bradycardia requiring permanent cardiac pacing. We aimed to compare the clinical outcomes of LBBAP, HBP, and RVAP in Japanese patients with bradycardia.

Methods: A total of 424 patients who underwent successful pacemaker implantation (HBP,  = 53; LBBAP,  = 75; and RVAP,  = 296) were retrospectively enrolled in this study.

Predicting interindividual response to theta burst stimulation in the lower limb motor cortex using machine learning.

Using theta burst stimulation (TBS) to induce neural plasticity has played an important role in improving the treatment of neurological disorders. However, the variability of TBS-induced synaptic plasticity in the primary motor cortex prevents its clinical application. Thus, factors associated with this variability should be explored to enable the creation of a predictive model.
