title: Laparoscopic placement of hepatic artery catheter for regional chemotherapy infusion: technique, benefits, and complications.
abstract: Approximately 15% to 18% of patients diagnosed with colorectal cancers present with metastases confined to the liver. Although many may undergo a liver resection procedure, some will not be candidates for surgery or will have recurrence of liver disease within the first 2 years after liver metastasis resection. For this subset of patients, regional hepatic chemotherapy, including intra-arterial chemotherapy, has been shown to improve control of the disease and, in some cases, prolong survival. With the advent of laparoscopic surgery and its application to more and more advanced procedures, the possibility of laparoscopic placement of a chemotherapy infusion catheter in the hepatic artery with all the advantages of a minimally invasive approach appears to be a viable alternative in our hands. From November 1993 through February 2002, 20 patients (12 male, 8 female) successfully underwent laparoscopic placement of a hepatic artery infusion catheter at the Texas Endosurgery Institute. Correct placement of the catheter was confirmed by methylene blue injections via the hepatic artery catheter at the time of surgery. Chemotherapy was generally initiated in the immediate postoperative period. Mean age was 68.3 years (range, 46-82). Twelve of the patients (60%) had previously undergone abdominal surgery. There were 27 major laparoscopic procedures performed at the time of hepatic artery catheter placement. There were no conversions to an open procedure. Mean operative time was 186 minutes (range, 125-280), and mean blood loss was 132 mL (range, 20-300). These values include the 27 major concurrent laparoscopic procedures performed at the time of catheter placement, including 18 cholecystectomies, 7 colectomies, and 2 liver resections. Median hospital stay was 3 days (range, 3-25), with a median return to regular diet of 3 days. There were no intraoperative complications and no deaths secondary to catheter placement. There were 2 late complications, for an overall rate of 10%. For all 17 patients with residual hepatic disease whose chemotherapy was successfully instituted, regression of the metastases was evident by abdominal computed tomographic criteria and CEA levels. Laparoscopic hepatic artery catheterization is both feasible and safe. It incurs all the benefits of a minimally invasive procedure and can be performed at the time of laparoscopic colectomy to avoid the necessity of a second procedure.
