Application of three dimensional reconstruction technique in selection of incision of thoracic surgical operation with robot.

ABSTRACT:

Objective

To evaluate a new method to plan the incisions of thoracic surgical operation with robot using three-dimensional (3D) reconstruction techniques.

Methods

Three-dimensional reconstruction techniques were used to reconstruct the chest CT of patients with the software OSIRIX (APPLE®). Tumor location, size and relationship with the vein and artery were unambiguously obtained. The location of the incision was predetermined prior to the surgery. The operation time, set up time and work time were evaluated to assess the efficacy of this preplanning methodology.

Results

A total of 4 cases are reported here. Tumors of different homogeneities were assessed, located in a 3D mode, and preplanned incisions successfully made to perform the procedure. This resulted in overall reduction of operation time and also provided effective visualization of the tumor during surgery.

Conclusion

Our results suggest that this method can show the location of tumor, help in planning of appropriate incisions and define 3D anatomical relationships.

Project description:Introduction and Objectives: Kidney autotransplantation can be performed in patients with complex renal or ureteral pathology not suitable for in situ reconstruction, such as renal vasculature anomalies, patients with proximal or long complex ureteral strictures, or complex oncological cases. Robot-assisted surgery allows for a high-quality vascular and ureteral anastomosis and faster patient recovery. Robot-assisted kidney autotransplantation (RAKAT) is performed in two phases: nephrectomy and pelvic transplantation. In-between, extraction of the kidney allows for vascular reconstruction or kidney modification on the bench and safe cold ischemia can be established. If no bench reconstruction is needed, total intracorporeal RAKAT (tiRAKAT) is feasible. One case report in Europe has been described; however, to our knowledge no surgical video is available. Methods: A 58 year-old woman suffered from right mid- and distal ureteral stenosis following pelvic radiotherapy 10 years prior for cervical cancer. A JJ stent was placed, but she suffered from recurrent urinary tract infections, and ultimately a nephrostomy was placed. Renogram demonstrated 43% relative right kidney function. As her bladder volume was low following radiotherapy, no Boari flap was possible and the patient refused life-long nephrostomy or nephrectomy. Therefore, tiRAKAT was performed using the DaVinci Xi system. Results: We describe our surgical technique including a video. Surgical time (skin-to-skin) was 5 h and 45 min. Warm ischemia time was 4 min, cold ischemia 55 min, and rewarming ischemia 15 min. The abdominal catheter and bladder catheter were removed on the first and second postoperative day, respectively. The JJ stent was removed after 4 weeks. The patient suffered from pulmonary embolism on the second postoperative day, for which therapeutic low molecular weight heparin was started. No further complications occurred during the first 90 postoperative days. After 7 months, overall kidney function remained stable, right kidney function dropped non-significantly from 27 to 25.2 mL/min (-6.7%) on renal scintigraphy. Conclusion: We demonstrated feasibility and, for the first time, a surgical video of tiRAKAT highlighting patient positioning, trocar placement, and intracorporeal cold ischemia technique.
