Laparoscopic anterior right hepatectomy (LARH) has been used in some hospitals. However, data on the feasibility and safety of this procedure are still limited, due to the demanding technical requirements. The primary objective of this study was to compare the clinical outcomes of LARH with those of laparoscopic conventional right hepatectomy (LCRH) in patients with large right hepatocellular carcinoma, as well as to confirm the safety and feasibility of LARH. Furthermore, the article presents a step-by-step description of the surgical procedures for LARH to help perform this surgery in the clinic. The principle of LARH is to first prioritize the hepatic inlet duct separation while separating the right hepatic perihepatic ligament after transecting the liver. From December 2015 to June 2022, 82 patients with large right hepatocellular carcinoma (maximum tumor diameter ≥ 5 cm), were recruited for the study. In this cohort, 54 and 28 patients underwent LARH and LCRH, respectively. The perioperative clinical data and survival outcomes of the two groups were compared. Compared with LCRH, LARH exhibited the advantages of less contact and extrusion, thereby leading to the achievement of superior results. Thus, we propose that LARH is the optimal choice for patients with large right hepatocellular carcinoma.

This case report and video demonstrate the technique of full-endoscopic J-shaped transforaminal L5 exiting nerve decompression in Bertolotti syndrome. Bertolotti syndrome, characterized by a congenital lumbosacral transitional vertebra, often results in mechanical lower back pain and nerve root compression. A 69-year-old male presented with progressive radiating pain in the right leg and tingling in the L5 dermatome.

Objective: To identify the risk factors for proximal junctional failure (PJF) after adult spinal deformity (ASD) surgery despite ideal sagittal correction according to age-adjusted alignment target.
Methods: The study included patients who underwent low thoracic to pelvic fusion for ASD and obtained ideal correction according to age-adjusted pelvic incidence minus lumbar lordosis. PJF was defined either radiographically as a proximal junctional angle (PJA) of >28° plus a difference in PJA of >22° or clinically as revision surgery for proximal junctional complications.

Background And Aims: Post-stroke dysphagia is highly prevalent and causes complication. While video games have demonstrated potential to increase patient engagement in rehabilitation, their efficacy in stroke patients with dysphagia remains unclear. This aim of this study was to explore the effectiveness of the artificial intelligence-based video-game (AI-VG) intervention in improving swallowing function among stroke patients with dysphagia.

Background: Lymphoma is a common hematological malignancy with diverse morphological and immunophenotypic characteristics that may affect treatment and outcomes. Thus, accurate differential diagnosis is crucial, and molecular genetic testing is valuable. We aimed to investigate the genetic characteristics of Korean patients with lymphoma using a next-generation sequencing (NGS)-based targeted panel.
