Laparoscopic Caudal Approach of the Inferior Vena Cava for Isolated Segment 1 Liver Resection.
Abstract Introduction:Isolated segment 1 laparoscopic liver resection is a very challenging procedure. Very few references are available about this laparoscopic technique, so the aim of this article is to show the main technical aspects of laparoscopic caudal approach for segment 1.Material and Methods: A 64 years old woman with a past medical history of a breast cancer previously operated (pT1N0M0, with positive hormonal receptors). Adjuvant treatment was done with radiotherapy and hormone-therapy (Tamoxifen). After 12 months of follow-up, a 18 mm single liver metastasis was detected in the segment 1, suggestive of metastatic disease. A complementary study was done with Magnetic Resonance Image, Computed Tomography and Positron Emission Tomography, without other lesions proven. Result:A laparoscopic resection of isolated liver segment 1 is performed with a caudal approach of the inferior vena cava. All the steps are carefully described. The surgery time was 120 minutes and the blood loss was less than 100 ml. No postoperative complications were registered. The patient was discharged on the third postoperative day.Conclusion:Liver 1 segment resection by laparoscopy with a caudal approach of the inferior vena cava is a secure technique in selected patients and it should be performed in experienced liver surgery and advanced laparoscopy centers, because of its high complexity.
