Introduction/Background The main surgical goal in ovarian cancer is achieving an optimal cytoreduction with no gross disease.

Upper abdominal debulking procedures demand higher surgical effort, several studies described up to 40% of improvement in optimal cytoreduction rate. Besides, it is recognized that complete cytoreduction is related with higher survival rates.

The dissection of the porta hepatis region is challenging, due to the risk of injury of the portal vein, the hepatic artery and the common bile duct.

Methodology We want to show throw this video a successful porta hepatis tumor resection. We will show anatomical marks, anatomical images and a step by step procedure, correlating the tumor load with RMI pictures of the patient.

- Supracolic omentectomy. Kocher Maneuver. Exposure of duodenum and pancreas. Exposure of the hepatoduodenal ligament. Peritonectomy of the hepatoduodenal ligament. Bile duct is individualized, a vessel-loop is useful to mark and move the structures. Dissection of the proper hepatic artery. Dissection of the common hepatic artery. Dissection of the portal vein. Resection of lymph nodes, anterior resection and retroportal nodes.

Results Traditionally porta hepatis disease was related with non-resectability.

Tumor debulking at porta hepatis region is feasable for some patients with low morbidity.

Anatomical knowledge and meticulous surgical technique should be mandatory.

Unresected tumor of porta hepatis may cause pain, obstructive jaundice and bowel obstruction.

Conclusion Surgical expertise in upper abdominal debulking techniques increase the optimal cytoreduction rate in ovarian cancer.

Managing porta hepatis debulking procedures increase our chances of accomplishing no gross residual disease, therefore, disease-free survival and overall survival of our patients may increase.
