The use of laparoscopic partial splenectomy has been limited due to the high risk of bleeding during surgery. Therefore, we introduce a laparoscopic method combined with microwave ablation to solve the problem of intraoperative bleeding.
The scope of our research is how to reduce BD and the postoperative complications in laparoscopic partial splenectomy. We found the microwave ablation to be an effective adjunct to hemostasis. The treatment of belying vein tumors is gradually treated with laparoscopic surgery, and the laparoscopic partial splenectomy is increasingly recognized because of its lack of trauma. Microwave ablation can quickly coagulate T-cells and reduce bleeding during parenchymal tumor resection, and is suitable for laparoscopic partial duodenectomy.
At present, there are still a few hospitals that use microwave ablation to assist in the laparoscopic partial splenectomy, and we have accumulated a lot of experience to make full use of this technique. We will further investigate whether microwave ablation is suitable for the surgical treatment of benign tumors of pancreas.
[Narrator] To begin, review the MRI image of the selected patient to assess the tumor's location, size, and nearby blood vessels. After placing seven French intravenous catheters and puncturing the radial artery on the anesthetized patient, use an ultrasonic knife to open the left gastrocolic ligament. Separate the gastrosplenic ligament to reveal the splenic portal while ligating the short gastric arteries during dissection. Isolate the lower pole branch of the spleen pedicle and ligate them with Hem-o-lok clamps. Dissect the splenic artery to identify the branches supplying blood to the tumor. Next, reveal the splenic hemangioma. Separate the splenocolic ligaments from the lower outer side of the spleen, and then separate the splenorenal ligaments from behind the spleen to fully free the target area. Identify the ischemic line between the normal spleen tissue and the fraction lacking blood supply. Next, insert a percutaneous microwave ablation needle. Coagulate the spleen tissue in phases with microwave ablation using 60 to 80 watts of power for three minutes. Ensure that the needle tip does not penetrate the spleen parenchyma, and that the ablation area remains on the same plane. Divide the spleen along the coagulation zone. Check for bleeding in the splenic section and observe the blood supply to the residual spleen. Finally, place the splenic fossa drainage tube. Hematoxylin and eosin staining showed splenic tissue with infarction, while CD34 immunohistochemistry staining confirmed the diagnosis of splenic hemangioma. Postoperative computed tomography scans one month after surgery showed good residual blood circulation in the spleen.
This study explores the use of microwave ablation as an adjunct to laparoscopic partial splenectomy to reduce intraoperative bleeding and postoperative complications. The findings suggest that this technique can enhance hemostasis during surgery.
