The Two-Step Treatment for Giant Hepatic Hemangiomas

Area of Science:

• Hepatobiliary Surgery
• Interventional Radiology
• Vascular Anomalies

Background:

• Giant hemangiomas (GH), defined as exceeding 10 cm in maximum diameter, present significant surgical challenges.
• Traditional treatment often involves upfront surgical resection, which can be complex and associated with substantial morbidity.

Purpose of the Study:

• To evaluate the feasibility and impact of a two-step treatment strategy for giant hemangiomas.
• This strategy combines transarterial embolization (TAE) with subsequent laparoscopic liver resection (LLR).

Main Methods:

• A retrospective analysis compared 10 patients with GH treated with TAE followed by LLR (Group A) to 10 matched patients treated with upfront LLR (Group B).
• Outcomes assessed included successful embolization, operative time, blood loss, complications, and length of hospital stay.

Main Results:

• Successful embolization was achieved in all Group A patients, with no immediate complications post-TAE.
• The TAE + LLR group showed statistically significant reductions in intraoperative blood loss (250 vs. 400 mL), operative time (245 vs. 420 min), and length of stay (5 vs. 8 days) compared to Group B.
• No conversions to laparotomy were required in the TAE + LLR group.

Conclusions:

• The two-step approach of TAE followed by LLR is a safe and effective option for managing giant hemangiomas (>10 cm).
• This combined strategy offers potential advantages in reducing surgical morbidity and improving patient outcomes.
