Summary of Research of Hepatic Hilar Region Lymph Node Resection in Cytoreductive Surgery for Advanced Ovarian Cancer

	Number of Patients	Incidence of PH/HCL Disease	Diagnosis Method	Surgery Related Morbidity	Complications Directly Related to Resection of Disease at the Porta Hepatis	DFS/OS
Martinez et al5	28	53.6% (celiac nodes) 67.9% (porta hepatis)	Intraoperative palpation	35.7%	One lateral common bile duct injury occurred during resection of tumor at the porta hepatis, and primary suture with drainage followed by intraoperative cholangiography to was performed.	NA
Song et al10	155	7.1% (11/155)	Preoperative physical examination and an abdominopelvic and chest CT	36.4%	Intraoperative complications specific for tumor resection at the porta hepatis, such as hemorrhage by injury to the hepatic artery or portal vein, bile leakage, and liver damage were not observed.	Five of 11 patients had recurrent disease at median 8 months (range, 1–13) after the surgery with a median follow-up of 8 months (range, 3–21 months).
Raspagliesi et al6	37	67% (25/37)	Total body CT scan: with PET scan performed if clinically indicated +intraoperative findings	21.6%	2/25 (1 bleeding due to liver damage and 1 due to left gastric artery injury)	NA
Tozzi et al7	216	14.3% (31/216)	CT scan and exploratory laparoscopy	29.2%	None	19 months/42 months
