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.

In this video, fertilized zebrafish embryos are dechorionated under a stereo microscope and then exposed to a cholesterol synthesis inhibitor, leading to the development of blood vessel ruptures and brain hemorrhages in the larvae. Hemorrhagic larvae, identifiable by distinct red spots, are subsequently separated under a microscope for further analysis.

FAQs
Bleeding becomes difficult to contain when vessel disruption exceeds the body’s coagulation response. The clinical effect depends on which vessel is injured, how much blood is lost, and whether underlying disease or medications impair clotting. The operation itself also matters because its tissue disruption and surgical conditions influence the ability to achieve effective hemostasis.
Blood loss reduces the circulating support needed to maintain tissue perfusion and oxygen delivery. As these decrease, patient stability may deteriorate, making prompt recognition and correction essential. The seriousness of the event therefore depends not only on visible bleeding, but also on its effects on hemodynamic status and the adequacy of oxygen supply to tissues.
Severity is influenced by the injured vessel, the nature of the operation, underlying disease, and medications that affect the coagulation response. These factors may limit the body’s ability to contain bleeding or make surgical control more difficult. Considering them during perioperative care helps the clinical team interpret blood loss and respond before instability worsens.
Recognition combines continuous observation of the operative field with estimation of blood loss, hemodynamic monitoring, and laboratory assessment. No single observation provides the complete picture: visible bleeding shows the local problem, while physiologic and laboratory findings indicate its effect on the patient and coagulation status. Together, these measures support timely decisions about control and replacement.
Management centers on prompt surgical hemostasis, meaning direct control of the bleeding source, together with fluid and blood-product replacement when needed. Clinicians also correct coagulation abnormalities that prevent effective clot formation. Coordinating these measures addresses both the immediate source of blood loss and the physiologic or coagulation consequences that can sustain instability.
Ongoing hemodynamic and laboratory monitoring helps determine whether interventions are restoring stability and correcting coagulation problems. Blood-loss estimation and operative-field observation show whether bleeding remains active, while physiologic and laboratory findings reveal its broader consequences. This information guides replacement, further hemostatic measures, and safer perioperative management in medicine.
