Laparoscopic Surgery for Advanced Gastric Cancer: Current Status and Future Perspectives
Ichiro Uyama,Koichi Suda,Seiji Satoh 대한위암학회 2013 Journal of gastric cancer Vol.13 No.1
Laparoscopic gastrectomy has been widely accepted especially in patients with early-stage gastric cancer. However, the safety and oncologic validity of laparoscopic gastrectomy for advanced gastric cancer are still being debated. Since the late 90s’, we have been engaged in developing a stable and robust methodology of laparoscopic radical gastrectomy for advanced gastric cancer, and have established laparoscopic distinctive technique for suprapancreatic lymph node dissection, namely the outermost layer-oriented medial approach. In this article, We present the development history of this method, and current status and future perspectives of laparoscopic gastrectomy for advanced gastric cancer based on our experience and a review of the literature.

Objective: The application of the da Vinci Surgical System in neurosurgery is limited due to technical difficulties requiring precise maneuvers and small instruments. This study details the advantages and disadvantages of robotics in neurosurgery and the reachable range of the transoral approach to lesions of the skull base and upper cervical spine. Methods: In a cadaver study, the da Vinci Xi robot, lacking haptic feedback, was utilized for sagittal and coronal approaches on 5 heads, facilitating dura suturing in 3, with a 30°-angled drill for bone removal. Results: Perfect exposure of all the nasopharyngeal sites, clivus, sellar, and choana, including the bilateral eustachian tubes, was achieved without any external incisions using this palatal split approach of transoral robotic surgery. The time required to perform a single stitch, knot, and complete single suture in robotic suturing of deep-seated were significantly less compared to manual suturing via the endonasal approach. Conclusion: This is the first report to show the feasibility of suturing the dural defect in deepseated lesions transorally and revealed that the limit of reach in the coronal plane via a transoral approach with incision of the soft palate is the foramen ovale. This preclinical investigation also showed that the transoral robotic approach is feasible for lesions extending from the sellar to the C2 in the sagittal plane. Refinement of robotic instruments for specific anatomic sites and future neurosurgical studies are needed to further demonstrate the feasibility and effectiveness of this system in treating benign and malignant skull base lesions.

Background: Minimally invasive liver resection including laparoscopic and robotic liver resection is a rapidly developing field withthe greatest potential. However, the spatial disorientation is one of the biggest issues that would increase the risk of dangerousbleeding and bile leakage. To overcome this issue, it is of crucial importance to standardize anatomical liver resection with extrahepaticGlissonean pedicle-first approach and to use advanced 3D liver simulation software that can visualize the Glissoneansystem.Methods: We proposed a novel concept of liver anatomy based on Laennec’s capsule that can standardize the extrahepaticGlissonean pedicle approach. Whereas Synapse 3D® is the first simulation software to use face recognition technology for clinical3D simulation and visualization of the Glissonean system are available since version 4.4.Results: Owing to the novel concept of liver anatomy, anatomical liver resection with extrahepatic Glissonean pedicle-first approachwas standardized and target area was well recognized prior to parenchymal dissection with minimal bleeding and bileleakage from the resecting plane. Preoperative 3D simulation and intraoperative navigation contributed to perform systematicanatomical liver resection without spatial disorientation even for the cases with anatomical abnormalities such as right-sidedligamentum teres.Conclusion: Minimally invasive liver resection including laparoscopic and robotic resection became safe and curable procedureswith the novel concept of liver anatomy and advanced 3D liver simulation.
