Simultaneous robot-assisted colorectal surgery for sigmoid colon cancer and portal vein embolization from the inferior mesenteric vein for intrahepatic cholangiocarcinoma: A case report and literature review.

INTRODUCTION AND

IMPORTANCE

The treatment of multiple cancers requires multidisciplinary expertise. In this case, we experienced a multiple cancers case, sigmoid colon cancer and intrahepatic cholangiocarcinoma that required preoperative portal vein embolization (PVE). PVE is often approached by trans-hepatic percutaneous approach or via ileocecal vein (ICV) or veins of the small intestine. In this case, the patient was scheduled to undergo robot-assist surgery for sigmoid colon cancer, and it was planned that the inferior mesenteric vein (IMV) would be cut. PVE from the IMV was performed with hope to reduce complications.

CASE PRESENTATION: This patient had intrahepatic cholangiocarcinoma and sigmoid colon cancer. A radical cure for intrahepatic cholangiocarcinoma was expected by left liver lobectomy. Because of concerns about postoperative liver failure, it was decided to perform PVE. PVE via IMV approach was performed simultaneously with robot-assisted surgery for sigmoid colon cancer. The patient was discharged without complications 12 days after surgery.

CLINICAL DISCUSSION: PVE is a very important technique for massive hepatic resection. Percutaneous trans-hepatic approach has the potential to damage vessels, bile duct, normal liver. Venous approaches, including via ICV, have the potential to damage vessels. In this case, we performed PVE from the IMV because we thought this approach would reduce the risk of complications. The patient successfully underwent PVE without complications.

CONCLUSION

PVE via IMV was successfully performed without complications. In multiple cancers case, this approach would be better approach than any other PVE approach like this case.
