Oncological Surgery - For cancers involving highly vascular organs like the liver or pancreas, or where tumors are located near critical structures, AI can provide immediate access to oncological databases, past case studies, and suggestions for intraoperative decisions based on real-time findings.
Surgeon: ChatGPT, I need the latest guidelines for intraoperative management of a hepatocellular carcinoma that's invading the right hepatic vein.
ChatGPT: The current guidelines recommend considering a partial hepatectomy with vascular reconstruction if the tumor involves major hepatic veins. Would you like details on the reconstruction techniques or postoperative care recommendations?
Surgeon: Start with the reconstruction techniques.
ChatGPT: For vascular reconstruction of the hepatic vein, options include using an autologous vein graft from the saphenous or internal jugular vein. Anastomosis can be performed using a continuous suturing technique with 5-0 Prolene to ensure patency. Monitoring for early signs of venous outflow obstruction is crucial in the immediate postoperative period.
Surgeon: What's the success rate for these reconstructions?
ChatGPT: Success rates for hepatic vein reconstructions vary, but generally, patency rates are about 90% at one year post-operation. The overall 5-year survival rate for patients undergoing this procedure for similar stages of hepatocellular carcinoma is approximately 60%, depending on the tumor's initial staging and margin status after resection.
Surgeon: And what about handling the tumor if it's adherent to surrounding structures?
ChatGPT: If the tumor is adherent to surrounding structures, it’s advisable to proceed with en bloc resection when feasible, to ensure clear margins. Intraoperative ultrasound should be used to assess the extent of invasion and to aid in precise dissection. Do you need guidance on specific dissection techniques or tools that could be effective in this scenario?
Surgeon: Yes, could you suggest the best dissection tool for a tumor adherent to the diaphragm?
ChatGPT: For dissection near the diaphragm, using an ultrasonic scalpel is advisable. It offers precision and minimizes thermal spread, which is crucial near delicate structures. Additionally, maintaining a clear surgical field with frequent irrigation can help in identifying tissue planes more clearly during dissection.
Surgeon: Let's say I encounter unexpected bleeding. What are the first steps I should take?
ChatGPT: For immediate management of unexpected bleeding, first, apply direct pressure. Assess the source of bleeding. If it's from a hepatic artery or smaller venous branches, temporary clamping can help in identifying the bleeding point. Consider using topical hemostatic agents such as Floseal or Surgicel. If bleeding persists, surgical revision of the vessels may be necessary. Would you like to prepare anything specific in case this occurs?
Surgeon: Prepare 5-0 Prolene and ensure the hemostatic agents are ready. Thanks, ChatGPT.
ChatGPT: You’re welcome! I’ll keep the information ready and continue to monitor the procedure. Let me know if there's anything else you need.

Surgeon: ChatGPT, confirm the protocol for margin assessment during a pancreaticoduodenectomy for a ductal adenocarcinoma.
ChatGPT: For a pancreaticoduodenectomy, intraoperative frozen section margin assessment is recommended. Ensure that margins from the pancreatic neck, bile duct, and duodenal stump are sent for histopathology. Do you need the details on handling the specimens or how to interpret possible results?
Surgeon: Yes, outline the procedure for specimen handling, please.
ChatGPT: After resection, the specimen should be oriented and labeled accurately before sending to pathology. Mark the surgical margins with ink—different colors for each margin can be helpful. Keep the specimen moist and send it immediately to avoid desiccation. Would you like to know the turnaround time for frozen sections?
Surgeon: That would be great, thanks.
ChatGPT: Typically, the turnaround time for intraoperative frozen sections is about 20-30 minutes, depending on the pathology lab's workflow. It’s advisable to coordinate with the pathology team ahead of time to ensure they are prepared for the specimen arrival to minimize waiting time.
Surgeon: What are the implications if the frozen section comes back positive for malignant cells at the margin?
ChatGPT: If the frozen section reveals positive margins, the recommendation is to resect more tissue, if feasible, aiming for a negative resection margin. This may involve further dissection around the pancreas or adjacent structures, depending on where the positive margin was detected. Would you like guidance on resection strategies or techniques in case of positive margins?
Surgeon: Yes, provide recommendations for extending the resection posteriorly.
ChatGPT: When extending resection posteriorly, carefully dissect along the plane behind the pancreas to avoid injury to the superior mesenteric artery and vein. Use blunt dissection and stay close to the pancreatic tissue to minimize risk to adjacent vascular structures. Consider using laparoscopic ultrasound to help identify the vascular anatomy and tumor margins more clearly.
Surgeon: What if I encounter significant fibrosis making dissection difficult?
ChatGPT: In cases of significant fibrosis, slow and meticulous dissection is crucial. Use sharp dissection techniques to better define the planes. Consider adjusting the angle of dissection and periodically reassess the anatomy with ultrasound. If bleeding occurs, maintain clear visualization by frequent suction and consider temporary packing to allow for better control.
Surgeon: Alright, set up the ultrasound for continuous feedback and notify pathology about the incoming specimens.
ChatGPT: Understood. Ultrasound will be ready for use, and I’ll inform pathology to expect the specimens shortly. Let me know if there’s anything else you need during the procedure.
