Tele-robot-assisted minimally invasive esophagectomy using a double-surgeon cockpit on a cadaver.

We conducted this study to evaluate the efficacy of robot-assisted minimally invasive esophagectomy (RAMIE) on cadavers in the prone position, utilizing telesurgical support through the double-surgeon cockpit (double SC) of the novel Japanese-made surgical robot system, hinotori (Medicaroid, Kobe, Japan). The Cadaveric Anatomy and Surgical Training Laboratory (CAST Lab) at Hokkaido University and Kushiro City General Hospital (KCGH) are interconnected by a dedicated 1 Gbps internet line, spanning 300 km. An operation unit and double SC were installed at CAST Lab, whereas the double SC proctor was installed at KCGH.

Real-time computed tomography fluoroscopy-guided dye marking prior to robotic pulmonary resection.

Background: The detection of tumor localization is difficult in robotic surgery because surgeons have no sense of touch and rely on visual information. This study aimed to evaluate the efficacy of preoperative CT-guided dye marking of lung nodules prior to robotic surgery.

Methods: Patients undergoing CT-guided dye marking prior to robotic surgery at our hospital between September 2019 and April 2024 were retrospectively analyzed.

Impact of COVID-19 on hospital visit behaviour in cancer patients in Japan: a nationwide study.

Objectives: Lockdowns and outing restrictions during the COVID-19 pandemic may have altered attitudes towards hospital visits. This study aimed to investigate changes in long-distance visits outside of secondary healthcare service areas (SHSA) among cancer patients in Japan.

Design: Retrospective observational study.

C5 palsy following one- or two-level anterior cervical discectomy and fusion: Incidence and neurological recovery in a retrospective neurosurgical multicenter study.

Background: C5 palsy is a frequent complication following cervical spine surgery, particularly after posterior approaches. Although several risk factors have been proposed, the incidence of C5 palsy after anterior cervical discectomy and fusion (ACDF) remains less well understood. This study aims to elucidate the risk factors and neurological recovery associated with C5 palsy following ACDF.
