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.

Intraoperative video consultation expedites and improves surgical care. Here, we present a case where intraoperative video consultation between a rural hospital and an academic hepatobiliary surgeon facilitated immediate diagnosis of bile duct transection during laparoscopic cholecystectomy, direct to operating room transfer between centers, and injury repair with robotic-assisted Roux-en-Y hepaticojejunostomy.
FAQs
Real-time internal views let clinicians compare what they see inside a hollow organ, duct, or surgical site with findings from the external operative field. This immediate information can reveal lesions, leaks, bleeding, or other issues while correction remains possible. The technique therefore supports decisions during the procedure rather than relying only on postoperative investigations.
The access route and the area requiring inspection help determine the instrument used. A flexible endoscope may be introduced through a natural opening, while a rigid endoscope may be used through a surgical access point. Both provide camera-based visualization, but their differing forms allow clinicians to match the examination approach to the operative site.
The examination can help identify lesions, locate bleeding, and detect leaks that may not be apparent from outside the organ or surgical field. It can also assess surgical margins and anastomoses, meaning connections created between tissues, and help confirm whether the intended procedure achieved its immediate technical result.
During the operation, clinicians establish access through a natural opening or surgical entry point, introduce the selected endoscope, and inspect the relevant interior region with its camera. They then interpret the findings in relation to the surgical field, use the information to guide or adjust the intervention when needed, and reassess procedural success.
Intraoperative Endoscopy is especially useful when important anatomy or procedural results cannot be adequately evaluated from the external operative field alone. Direct inspection can clarify suspected leaks, bleeding, lesions, margins, or anastomoses during surgery. Its value is greatest when immediate confirmation can influence ongoing management and potentially reduce the need for additional postoperative investigations.
After the main surgical steps, clinicians can use internal visualization to examine the treated area and check findings such as anastomotic integrity, surgical margins, or persistent bleeding. This provides immediate evidence about the procedure's result before the operation ends. Such confirmation can support timely correction when the findings do not match the intended outcome.
