In early gastric cancer, the aim of surgery is to precisely remove the distal stomach including the primary tumor. To do this, accurate localization of the tumor is crucial, especially in totally laparoscopic surgery. This protocol describes a procedure for intraoperative gastroscopy in totally laparoscopic subtotal gastrectomy.

We describe here the use of a pH-sensitive green fluorescent protein variant, pHluorin, to study the spatio-temporal dynamics of axon guidance receptors trafficking at the cell surface. The pHluorin-tagged receptor is expressed both in cell culture and in vivo, using electroporation of the chick embryo.
FAQs
Adaptation comes from treating intra-operative information as an ongoing reference rather than a one-time plan. As tissue position or condition changes, updated imaging, anatomical landmarks, navigation information, or physiological monitoring can help clinicians reassess localization and targeting. This feedback supports decisions that remain aligned with the anatomy and its condition at that stage of the operation.
Surgical navigation primarily supports localization, while intra-operative imaging can provide information about tissue during the operation. Anatomical landmarks offer reference points, and physiological monitoring adds feedback about changing bodily conditions. Because these inputs address different aspects of the surgical situation, combining them can give clinicians a more complete basis for judging target position, tissue status, and proximity to critical structures.
Real-time feedback matters because the operative environment can change as tissue moves or its condition evolves. Guidance tools help clinicians re-evaluate where a target lies and how closely the planned action remains aligned with surrounding anatomy. That capability can support precise tissue targeting, help avoid critical structures, and make minimally invasive procedures more controlled.
Integration begins with surgical planning and continues as the procedure progresses. Clinicians use anatomical landmarks and navigation to maintain orientation, consult intra-operative imaging to reassess tissue, and consider physiological monitoring as conditions change. The resulting cycle of localization, assessment, and decision-making helps the team adjust its actions instead of treating the initial plan as fixed.
Clinicians may apply these approaches when accurate tissue targeting, limited access, or protection of nearby critical structures is important. They are particularly relevant to minimally invasive procedures, where precise orientation can support careful decision-making. The broader medical context includes use across specialties, with the specific combination of guidance tools shaped by the procedure and its anatomical demands.
The medical value extends beyond a single operative decision. By supplying feedback during surgery, guidance can connect the original plan with the patient’s changing anatomy or tissue condition. This may strengthen procedural safety and precision while contributing to more personalized treatment. Continued development is also relevant to improving surgical planning, especially when decisions must be refined during the operation.
