Abstract

Background: The caudate lobe is located deep in the dorsal portion of the liver. Complete resection is an extremely demanding surgery due to the limited surgical field, especially in cases with severe intra-abdominal complications. A major concern of isolated caudate lobectomy is the difficulty associated with securing the contralateral visual field during parenchymal transection. To overcome this issue, we present a new technique for isolated caudate lobectomy that uses a modified hanging maneuver.

Methods: We performed an anatomical isolated caudate lobectomy via the high dorsal resection technique using our new modified hanging maneuver in two patients with HCC in November and December 2019.

Results: Patient 1 was severely obese, so the upper abdominal cavity was occupied by a large amount of great omental fat, and fibrous adhesions were observed around the spleen. Patient 2 had undergone six preoperative treatments, and a high degree of adhesion was observed in the abdominal cavity around the liver. It was difficult to secure the surgical field due to severe abdominal complications in both cases. The total operation times in these two cases were 617 and 763 min, respectively, while the liver parenchymal dissection times of the caudate lobe were 96 and 108 min, respectively. The resection margin was negative in both patients (R0). Neither patient had any complications after surgery; both were discharged on postoperative day 14.

Conclusion: Our modified hanging maneuver is useful, particularly in cases with a narrow surgical field due to severe adhesions, bulky tumors, and/or hypertrophy of the Spiegel lobe.
