| Annals Surgical Oncology DOI ASO Laparoscopic Placement Hepatic Artery Infusion Pumps Technical Considerations and Early Results Jun Cheng PhD Dennis Hong Guojing Zhu Lee Swanstrom and Paul Hansen Background Laparoscopic hepatic artery infusion pump LHAIP placement novel treatment option for patients with colorectal liver metastases This study investigates technical difficulties with regard variant hepatic arteries and the preliminary outcomes for patients treated with LHAIP placement Methods Between March and January patients with colorectal metastases confined the liver who had prior systemic chemotherapy that failed were treated with LHAIP Results Twelve patients had LHAIP placement only and had pump placement combined with laparoscopic radiofrequency ablation LRFA patients and liver resection patients Variant hepatic arterial anatomy was present patients The presence variant did not increase pump complications operative time blood loss decrease the functional time pump use comparison with normal anatomy all patients with variant laparoscopic ligation the variant vessel and cannulation nongastroduodenal artery resulted complete hepatic perfusion Three misperfusions identified intraoperatively with use methylene blue injection were corrected laparoscopic ligation two postoperative angioembolization one Postoperative pump radionuclide flow studies confirmed isolated hepatic artery infusion all cases There was pump related complication rate During median follow months months .
