Repeated robotic pancreatectomy for recurrent pancreatic metastasis of mesenchymal chondrosarcoma: A case report

Abstract

AbstractMesenchymal chondrosarcoma is a rare subset of sarcomas accounting for 3%–10% of all cases of chondrosarcomas. Radical resection is the only curative strategy, even in patients with metastatic tumors. However, data regarding treatment strategies remain limited owing to the small number of cases. Herein, we report a patient who underwent repeated robotic pancreatectomy for recurrent pancreatic metastasis originating from extraskeletal mesenchymal chondrosarcoma of the pelvis. First, robotic pancreaticoduodenectomy with a reconstruction of pancreaticogastrostomy was performed for synchronous pancreatic metastasis 5 months after the primary resection of mesenchymal chondrosarcoma. Ten months after robotic pancreaticoduodenectomy, tumor recurrence was observed at the tail end of the pancreas, which was removed by reperforming robotic distal pancreatectomy. Given the precise tissue manipulation that can be achieved with robotic articulated forceps, the peripheral splenic artery and pancreas were easily isolated and divided in close proximity to the tumor. The central part of the pancreas was preserved. Robotic surgery allowed safe and effective resection of the reconstructed remnant pancreas. The patient survived for 28 months after primary tumor resection. Repeated pancreatectomy with minimally invasive techniques is a feasible and curative treatment for metastatic mesenchymal chondrosarcoma.
